Description

Molding equipment and molding methods for manufacturing radomes

[0001] This invention is based on and claims priority to the CN applications with application number CN202510127691.X, filed on February 4, 2025 and CN202510523174.4, filed on April 23, 2025. The disclosure of the CN applications is incorporated herein by reference in its entirety. Technical Field

[0002] This disclosure relates to the field of base station antennas. More specifically, this disclosure relates to molding equipment and molding methods for manufacturing radomes. Background Technology

[0003] Currently, extrusion molding is used to produce radomes. In this method, thermoplastic is heated and pressurized in an extruder, forcing it through a die and a shaping mold of a predetermined shape. The plastic then solidifies directly, producing a product with a fixed cross-section and a certain length. During extrusion, the thermoplastic is softened by thermocouples in the extruder, forming a specific shape in the die. It is then rapidly cooled in a cooling and shaping sleeve, and finally, through drawing, cutting, and inspection, becomes the finished product. This method allows for the continuous production of radomes with specific cross-sectional shapes, offering high production efficiency and making it suitable for producing large-sized radomes with relatively simple shapes.

[0004] In extrusion molding, if only a die and a shaping die of a defined shape are used to obtain a radome with a defined cross-sectional shape, then for radomes with different cross-sectional shapes, a matching die and a shaping die are required for each radome with a specific cross-sectional shape. This significantly increases costs and involves considerable time consumption during die changes. Furthermore, in conventional extrusion molding processes, the characteristics of the die and the plastic material make it difficult to mold structures with sharp edges. Therefore, there is an urgent need for molding equipment and methods for manufacturing radomes that provide the possibility of producing radomes with various specific cross-sectional shapes with less cost. In addition, the molding equipment and methods should also be able to produce structures with sharp edges. Summary of the Invention

[0005] Therefore, the object of this disclosure is to provide molding equipment and methods for manufacturing radomes, which enable the production of radomes with various specific cross-sectional shapes at a lower cost. Furthermore, the molding equipment and methods can produce structures with sharp edges.

[0006] Therefore, according to a first aspect of this disclosure, a molding apparatus for manufacturing a radome is provided, the molding apparatus comprising: a die configured to output a radome-molded part capable of having a longitudinal structure extending in a longitudinal direction; a cooling device arranged downstream of the die and configured to cool the radome-molded part; a traction device arranged downstream of the cooling device and configured to pull the radome-molded part; and a reprocessing device fixedly arranged upstream of the cooling device or fixedly arranged downstream of the cooling device and upstream of the traction device, the reprocessing device being configured to process the initial longitudinal structure of the radome-molded part by subtractive processing to obtain a final longitudinal structure, thereby manufacturing a radome-molded part with the final longitudinal structure.

[0007] In this disclosure, by providing an additional reprocessing unit, subtractive processing can be performed on the radome-molded part output from the die. This allows for adaptation to different specific cross-sectional shapes, particularly different longitudinal structures, by changing the arrangement and construction of the reprocessing unit. Compared to changing the die and its matching mold, using an additional reprocessing unit is less costly and requires less time to switch the arrangement and construction of the reprocessing unit. Furthermore, this reprocessing unit can employ subtractive processing techniques, thereby producing structures with sharp edges. Additionally, by providing an additional reprocessing unit, higher precision longitudinal structures can be obtained through subtractive processing with higher accuracy. Moreover, in this disclosure, the reprocessing unit is located on the production line, enabling "in-line" radome processing. Compared to post-processing after the radome has cured, this "in-line" radome subtractive processing causes less damage to the radome and is more advantageous for precision control. Furthermore, "in-line" radome subtractive processing also achieves lower costs.

[0008] In some embodiments, the reprocessing apparatus is configured to produce a final longitudinal structure that can alter the wind load characteristics of the radome-molded part or facilitate cooperation with a corresponding mating structure. The final longitudinal structure of this disclosure can achieve different purposes depending on its structure and arrangement, such as altering the wind load characteristics of the radome-molded part or facilitating cooperation with a corresponding mating structure.

[0009] In some embodiments, the reprocessing apparatus is arranged upstream or downstream of the cooling apparatus such that the radome-molded part can be processed by the reprocessing apparatus while it is not fully cured. Subtractive processing of the radome-molded part while it is not fully cured causes less damage to the radome and is also more advantageous for precision control.

[0010] In some embodiments, the reprocessing unit is arranged upstream or downstream of the cooling unit. This allows for a more suitable degree of stiffness in the radome-molded part.

[0011] In some embodiments, the reprocessing apparatus includes a tool assembly, wherein the output orifice of the die is shaped such that the initial longitudinal structure has a section where the material thickness changes, wherein the section where the material thickness changes in the initial longitudinal structure includes a thickness transition portion with machining allowance, and the tool assembly is arranged at a position corresponding to the initial longitudinal structure and configured to machine at least a portion of the thickness transition portion of the section where the material thickness changes in the initial longitudinal structure of the radome-formed part, to obtain the corresponding final longitudinal structure. Thus, the task of obtaining the final longitudinal structure can be assigned to the die and the tool assembly of the reprocessing apparatus, wherein the die is responsible for forming the main body of the longitudinal structure, while the reprocessing apparatus is responsible for machining the critical thickness transition portion. This division of labor achieves good cost and precision control not only for the die but also for the reprocessing apparatus, and can meet the requirements for the formed shape and the machining accuracy requirements of the thickness transition surface. Furthermore, by using the tool assembly, structures with sharp edges can be machined.

[0012] In some embodiments, the output port of the die is shaped such that an initial longitudinal structure is formed on the side and / or front and / or back of the radome-molded part, and the cutting tool assembly is arranged and configured to process the initial longitudinal structure on the side and / or front and / or back of the radome-molded part. Thus, when the initial longitudinal structure is formed on the side and / or front of the radome-molded part, targeted processing by a subsequent reprocessing device can achieve favorable wind load characteristics, and when the initial longitudinal structure is formed on the back of the radome-molded part, targeted processing by a subsequent reprocessing device can achieve a good fit with the mating structure.

[0013] In some embodiments, the shape of the die's output port is configured such that the initial longitudinal structure exiting the die's output port is symmetrically or asymmetrically constructed about a central plane on both sides of the radome-formed part, and the tooling assemblies are correspondingly arranged symmetrically or asymmetrically about the central plane, which is parallel to the sides of the radome-formed part and extends through the center of the radome-formed part. Thus, a symmetrical or asymmetrical arrangement of the longitudinal structure can be adopted according to actual needs.

[0014] In some embodiments, the tooling assembly includes: a single-sided tool with a cutting head having two cutting edges and a cutting tip, configured to machine a thickness transition portion of a section where the material thickness of the initial longitudinal structure changes, to obtain the corresponding final longitudinal structure; and / or a double-sided tool with two opposing cutting heads, each having two cutting edges and a cutting tip, configured to simultaneously machine two thickness transition portions of a section where the material thickness of the initial longitudinal structure changes, to obtain the corresponding final longitudinal structure. Thus, single-sided or double-sided tools can be flexibly used for different situations. Single-sided tools offer greater flexibility and can meet various machining requirements, while double-sided tools are more advantageous for the thickness transition portions on both sides of a protruding structure, better ensuring the machining accuracy of the thickness transition portions on both sides of the protruding structure. Furthermore, by using the aforementioned single-sided and double-sided tools, structures with sharp edges can be machined.

[0015] In some embodiments, the plane formed by the two cutting edges of the respective cutter head is perpendicular to the longitudinal central axis of the radome-formed part. This allows for a smooth subtractive manufacturing process.

[0016] In some embodiments, in the corresponding cutter head, the two corresponding cutting edges are perpendicular to each other, form acute angles with each other, or form obtuse angles with each other; and / or the corresponding cutting tips are constructed at right angles, are convex arcs, are inclined, are concave arcs, are acute angles, or are obtuse angles. Therefore, for single-sided and / or double-sided cutters, the corresponding cutting tip shape and cutting edge form can be selected according to the actual situation, such as the desired wind load characteristics or the mating structure to be used, to meet different application requirements. This is more cost-effective and flexible compared to changing the die. Furthermore, changing different cutter heads or cutters does not require excessive time.

[0017] In some embodiments, a cutting tip constructed at a right angle can process the corresponding thickness transition portion of a section in the initial longitudinal structure where the material thickness changes into a thickness transition portion that is at least partially right-angled; or a cutting tip constructed with an outwardly convex arc shape can process the corresponding thickness transition portion of a section in the initial longitudinal structure where the material thickness changes into a thickness transition portion that is at least partially concave arc shape; or a cutting tip constructed at an angle can process the corresponding thickness transition portion of a section in the initial longitudinal structure where the material thickness changes into a thickness transition portion that is at least partially angled. The tool tip can be used to process the thickness transition section of the initial longitudinal structure where the material thickness changes into at least a partially convex arc-shaped thickness transition section; or, using a tool tip with an acute angle, it can process the thickness transition section of the initial longitudinal structure where the material thickness changes into at least a partially acute angle thickness transition section; or, using a tool tip with an obtuse angle, it can process the thickness transition section of the initial longitudinal structure where the material thickness changes into at least a partially obtuse angle thickness transition section. Thus, thickness transition sections of various suitable shapes can be machined according to requirements.

[0018] Here, the acute or obtuse angle of the cutting tip can be a concave acute or obtuse angle, thereby machining a thickness transition portion with an outward convex acute or obtuse angle; or the acute or obtuse angle of the cutting tip can also be an outward convex acute or obtuse angle, thereby machining a thickness transition portion with a concave acute or obtuse angle.

[0019] In some embodiments, the output port of the die is shaped such that the initial longitudinal structure has at least two protrusions extending longitudinally along the radome-molded part, protruding on a straight side region of the radome-molded part. The first protrusion smoothly transitions to the arcuate corner region of the radome-molded part on one side and forms a first thickness transition portion with machining allowance on the other side. The second protrusion forms second thickness transition portions with machining allowance on both sides. Thus, an initial longitudinal mechanism suitable for improving the wind load characteristics of the radome can be provided by a die of a specific shape, forming a groove-protrusion composite structure.

[0020] In some embodiments, the die's output opening is shaped such that a first protrusion is near the front of the radome-molded part, and a second protrusion is near the back of the radome-molded part. Thus, a favorable initial longitudinal structure suitable for improving the wind load characteristics of the radome can be provided through a die of a specific shape.

[0021] In some embodiments, the shape of the die's output port is configured such that a first protrusion is located in the front transition region where the radome-formed part transitions from a straight side region to a front curved corner region, while a second protrusion is located near the rear transition region where the radome-formed part transitions from a straight side region to a rear curved corner region. Thus, a favorable initial longitudinal structure suitable for improving the wind load characteristics of the radome can be provided by a die of a specific shape.

[0022] In some embodiments, the tooling assembly is arranged and configured to machine the first thickness transition portion of the first protrusion with a single-sided tool to obtain the final first thickness transition portion, and to machine the second thickness transition portions on both sides of the second protrusion with a double-sided tool or a combination of two single-sided tools to obtain the final second thickness transition portions, thereby obtaining the corresponding final longitudinal structure. Thus, based on an initial longitudinal structure suitable for improving the wind load characteristics of the radome provided by the die, a final longitudinal structure with improved wind load characteristics of the radome is obtained by subtractive machining of the individual thickness transition portions of the initial longitudinal structure. Furthermore, for the second thickness transition portions on both sides of the second protrusion, a double-sided tool or a combination of two single-sided tools can be used as needed, provided that accuracy requirements are met, to satisfy different machining requirements or requirements for the shape of the thickness transition portions.

[0023] In some embodiments, the respective blade tips of the single-sided and / or double-sided blades of the blade assembly are shaped such that the final first thickness transition is at least partially right-angled, convex, inclined, concave, acute, or obtuse; and the final second thickness transition is at least partially right-angled, convex, inclined, concave, acute, or obtuse. Thus, different blade tip shapes can be used depending on the specific wind load characteristics to be met.

[0024] In some embodiments, the output port of the die is shaped such that the initial longitudinal structure has a third protrusion extending longitudinally along the radome-molded part, protruding on a straight side region of the radome-molded part, and a fourth protrusion extending longitudinally along the radome-molded part, protruding from the third protrusion. The third protrusion has a third thickness transition portion with machining allowance on both sides, and the fourth protrusion has a fourth thickness transition portion with machining allowance on both sides. Thus, a die of a specific shape can provide another initial longitudinal mechanism suitable for improving the wind load characteristics of the radome, forming a boss-protrusion composite structure.

[0025] In some embodiments, the shape of the die's output opening is configured such that the third protrusion extends along the entire straight side region of the radome-molded part. This allows for the provision of an advantageous initial longitudinal structure suitable for improving the wind load characteristics of the radome through a die of a specific shape.

[0026] In some embodiments, the output port of the die is shaped such that a fourth protrusion is located at the end of the third protrusion, such that a third thickness transition portion of the third protrusion and a fourth thickness transition portion of the fourth protrusion merge at that end of the third protrusion to form a fifth thickness transition portion. Thus, a favorable initial longitudinal structure suitable for improving the wind load characteristics of the radome can be provided by a die of a specific shape.

[0027] In some embodiments, the output port of the die is shaped such that the fourth protrusion is located at the end of the third protrusion near the rear arcuate corner region of the radome-molded part. Thus, a favorable initial longitudinal structure suitable for improving the wind load characteristics of the radome can be provided by a die of a specific shape.

[0028] In some embodiments, the tooling assembly is arranged and configured to machine, with corresponding single-sided tools, the remaining third thickness transition of the third protrusion, the remaining fourth thickness transition of the fourth protrusion, and the fifth thickness transition formed by the third thickness transition of the third protrusion and the fourth thickness transition of the fourth protrusion, thereby obtaining the final third thickness transition, the final fourth thickness transition, and the final fifth thickness transition to obtain the corresponding final longitudinal structure. Thus, based on an initial longitudinal structure provided by the die suitable for improving the wind load characteristics of the radome, a final longitudinal structure with improved wind load characteristics of the radome is obtained by subtractive machining of the individual thickness transitions of the initial longitudinal structure.

[0029] In some embodiments, the tooling assembly is arranged and configured to machine the third thickness transition portions on both sides of the third protrusion with a single-sided tool to obtain the final third thickness transition portion, and to machine the fourth thickness transition portions on both sides of the fourth protrusion with a double-sided tool or a combination of two single-sided tools to obtain the final fourth thickness transition portion, thereby obtaining the corresponding final longitudinal structure. Thus, based on an initial longitudinal structure suitable for improving the wind load characteristics of the radome provided by the die, a final longitudinal structure with improved wind load characteristics of the radome is obtained by subtractive machining of the individual thickness transition portions of the initial longitudinal structure. Furthermore, for the fourth thickness transition portions on both sides of the fourth protrusion, a double-sided tool or a combination of two single-sided tools can be used as needed, provided that accuracy requirements are met, to satisfy different machining requirements or requirements for the shape of the thickness transition portions.

[0030] In some embodiments, the blade tip of the corresponding single-sided blade of the blade assembly is shaped such that the final third thickness transition is at least partially right-angled, convex, inclined, concave, acute, or obtuse; the final fourth thickness transition is at least partially right-angled, convex, inclined, concave, acute, or obtuse; and / or the final fifth thickness transition is at least partially right-angled, convex, inclined, concave, acute, or obtuse. Thus, different blade tip shapes can be used depending on the specific wind load characteristics to be met.

[0031] In some embodiments, the tip size of the single-sided tool used for the fifth thickness transition section is larger than the tip size of the corresponding single-sided tool used for the third or fourth thickness transition section. Therefore, a single-sided tool of a specific size can be used specifically for the fifth thickness transition section.

[0032] According to a second aspect of this disclosure, a molding apparatus for manufacturing an radome is provided, the molding apparatus comprising: a die configured to output an radome-molded part; a cooling device disposed downstream of the die and configured to cool the radome-molded part; a traction device disposed downstream of the cooling device and configured to pull the radome-molded part; and a reprocessing device configured to reprocess the radome-molded part in the production line, wherein the reprocessing device is at least partially fixedly disposed upstream of the cooling device or disposed downstream of the cooling device and above the traction device. The reprocessing apparatus includes a rotary tool assembly configured to perform subtractive machining on the initial longitudinal structure of the radome-formed part generated by the die through its own rotational motion; or the reprocessing apparatus is configured to perform additive machining on the surface of the radome-formed part to produce a final longitudinal structure; and / or the reprocessing apparatus includes a machining head rotatable about the radome-formed part, the machining head configured to perform subtractive or additive machining on the surface of the radome-formed part while rotating about the radome-formed part, in combination with the pulling motion of the traction device to produce a final helical structure.

[0033] In this disclosure, when a longitudinal structure is manufactured using subtractive machining, a rotary tool assembly can be used to perform subtractive machining on the radome-formed part output from the die through its own rotational motion, thereby appropriately manufacturing a radome with a final longitudinal structure of suitable size and sharp edges. For manufacturing different longitudinal structures, using a rotary tool assembly with rotational motion is less costly than changing the die and its mating mold, and the time required for changing the arrangement and structure of the rotary tool assembly is also less. Furthermore, by setting up a rotary tool assembly, a higher precision longitudinal structure can be obtained by using subtractive machining measures with higher precision. Similarly, when a longitudinal structure is manufactured using additive machining, a radome with a final longitudinal structure of suitable size and sharp edges can also be appropriately manufactured. For manufacturing different longitudinal structures, using an additive reprocessing apparatus is less costly than changing the die and its mating mold, and different longitudinal structures can be manufactured simply by adjusting the machining parameters and / or arrangement of the additive reprocessing apparatus. Furthermore, when using subtractive or additive manufacturing to produce a helical structure, a suitable helical structure can be produced using a machining head that rotates around the radome-molded part. The rotational speed of the machining head rotating around the radome-molded part and the traction speed of the traction device can be adjusted in combination to produce a helical structure with a suitable pitch and helix angle. This machining head can also produce helical structures with sharp edges and high precision. Moreover, in this disclosure, the reprocessing device is located within the production line, thus enabling "in-line" radome machining. Compared to subtractive machining performed after the radome has cured, this "in-line" radome subtractive machining causes less damage to the radome when using subtractive machining, or even no damage when using additive machining. Both "in-line" machining methods are also more advantageous for precision control. Furthermore, lower costs can be achieved through "in-line" radome subtractive or additive machining.

[0034] In some embodiments, the reprocessing apparatus is configured to produce a final longitudinal structure and / or a final helical structure in conjunction with the pulling motion of the traction device, the final longitudinal structure and / or the final helical structure being capable of altering the wind load characteristics of the radome-molded part or facilitating its mating with a corresponding pairing structure. The final longitudinal structure and / or the final helical structure of this disclosure can achieve different purposes depending on their own structure and arrangement, such as altering the wind load characteristics of the radome-molded part or facilitating its mating with a corresponding pairing structure.

[0035] In some embodiments, for subtractive processing, the reprocessing device is arranged upstream or downstream of the cooling device so that the radome-molded part can be processed by the reprocessing device before it is fully cured; for additive processing, the reprocessing device is arranged upstream of the cooling device so that the additive material applied to the radome-molded part can be cured by the cooling device. Subtractive processing of the radome-molded part before it is fully cured causes less damage to the radome and is also more advantageous for precision control. Furthermore, cooling after additive processing allows the same cooling device to simultaneously achieve curing and overall cooling functions, thus enabling the reuse of the cooling device.

[0036] In some embodiments, the reprocessing device is arranged upstream or downstream of the cooling device. This allows for a more suitable degree of stiffness in the radome-molded part.

[0037] In some embodiments, the shape of the output port of the die is configured such that an initial longitudinal structure is formed on the side and / or front and / or back of the radome-molded part, and the reprocessing apparatus for processing the final longitudinal structure is arranged and configured to process the initial longitudinal structure on the side and / or front and / or back of the radome-molded part. Thus, when the initial longitudinal structure is formed on the side and / or front of the radome-molded part, targeted processing by the subsequent reprocessing apparatus can achieve favorable wind load characteristics, and when the initial longitudinal structure is formed on the back of the radome-molded part, targeted processing by the subsequent reprocessing apparatus can achieve a good fit with the mating structure.

[0038] In some embodiments, the shape of the die's output port is configured such that the initial longitudinal structure emerging from the die's output port is symmetrically or asymmetrically constructed about a central plane on both sides of the radome-formed part, and the reprocessing apparatus for producing the final longitudinal structure is correspondingly arranged symmetrically or asymmetrically about a central plane, wherein the central plane is parallel to the sides of the radome-formed part and extends through the center of the radome-formed part. Thus, a symmetrical or asymmetrical arrangement of the longitudinal structure can be adopted according to actual needs.

[0039] In some embodiments, the reprocessing apparatus further includes a stationary fixed tool assembly for subtractive machining of the initial longitudinal structure. The fixed tool assembly includes: a single-sided tool with a cutting head having two cutting edges and a tip, configured to subtract material from one side of the initial longitudinal structure; and / or a double-sided tool with two opposing cutting heads, each having two cutting edges and a tip, configured to simultaneously subtract material from both sides of the initial longitudinal structure. Thus, the additional fixed tool assembly enables more suitable machining of the initial longitudinal structure, resulting in better machining of structures with sharp edges.

[0040] In some embodiments, the initial longitudinal structure is generated by a die, wherein the shape of the die's output opening is configured such that the initial longitudinal structure has a section where the material thickness changes. This section of the initial longitudinal structure includes a thickness transition portion with machining allowance. The rotary tool assembly is positioned corresponding to the initial longitudinal structure and configured to machine at least a portion of the thickness transition portion of the section where the material thickness changes in the initial longitudinal structure of the radome-formed part. Thus, obtaining the final longitudinal structure can be assigned to the die and the rotary tool assembly of the reprocessing device. The die is responsible for forming the main body of the longitudinal structure, while the reprocessing device is responsible for machining the critical thickness transition portion. This division of labor achieves good cost and precision control not only for the die but also for the reprocessing device, and meets the requirements for the formed shape and the machining accuracy of the thickness transition surface.

[0041] In some embodiments, the rotary tool assembly includes: a cylindrical end mill with a first milling head rotatable about a first milling rotation axis extending perpendicular to the surface of the radome-formed part for subtractive machining of the initial longitudinal structure; and / or a hob with at least one second milling head rotatable about a second milling rotation axis extending parallel to the surface of the radome-formed part and orthogonal to the longitudinal axis of the radome-formed part for subtractive machining of the initial longitudinal structure. Thus, cylindrical end mills and / or hobs can be flexibly used for different situations. Cylindrical end mills offer greater flexibility in meeting various machining requirements, while hobs are more advantageous for the thickness transition portions on both sides of a protruding structure, better ensuring the machining accuracy of these thickness transition portions. Furthermore, by using the aforementioned cylindrical end mills and hobs, structures with sharp edges can be machined.

[0042] In some embodiments, the initial longitudinal structure includes a protrusion, wherein at least two cylindrical end mills are provided for the protrusion, arranged sequentially along the extension direction of the protrusion, and positioned on both sides of the protrusion for subtractive machining of the two sides of the protrusion; and / or, for the protrusion, a hobbing cutter has two second milling heads that mate with the protrusion, positioned on both sides of the protrusion for subtractive machining of the two sides of the protrusion. Thus, cylindrical end mills and / or hobbing cutters can be flexibly used for cases with protrusions. By using the above-described cylindrical end mills and hobbing cutters, protrusions with sharp edges can be machined.

[0043] In some embodiments, the output port of the die is shaped such that the initial longitudinal structure has at least two protrusions extending longitudinally along the radome-molded part, protruding on a straight side region of the radome-molded part. The first protrusion smoothly transitions to the arcuate corner region of the radome-molded part on one side and forms a first thickness transition portion with machining allowance on the other side. The second protrusion forms second thickness transition portions with machining allowance on both sides. Thus, an initial longitudinal mechanism suitable for improving the wind load characteristics of the radome can be provided by a die of a specific shape, forming a groove-protrusion composite structure.

[0044] In some embodiments, the shape of the output port of the die is configured such that...

[0045] The first protrusion is located near the front of the radome-molded part; and / or

[0046] The second protrusion is located near the back of the radome-molded part; and / or

[0047] The first protrusion is located in the front transition region of the radome-molded part, where it transitions from a straight side region to a front curved corner region, while the second protrusion is located in the rear transition region, near the rear curved corner region of the radome-molded part. Thus, an advantageous initial longitudinal structure suitable for improving the wind load characteristics of the radome can be provided through a die of a specific shape.

[0048] In some embodiments, the tooling assembly is arranged and configured to machine the first thickness transition portion of the first protrusion with a single cylindrical end mill and / or a hob cutter, thereby obtaining the final first protrusion, and to machine the second thickness transition portions on both sides of the second protrusion with a combination of two cylindrical end mills and / or two second milling heads of a hob cutter, thereby obtaining the final second protrusion, to obtain the corresponding final longitudinal structure. Thus, based on an initial longitudinal structure suitable for improving the wind load characteristics of the radome provided by the die, a final longitudinal structure with improved wind load characteristics of the radome is obtained by subtractive machining of the individual thickness transition portions of the initial longitudinal structure. Furthermore, cylindrical end mills and / or hob cutters can be used here as needed, provided that accuracy requirements are met, to satisfy different machining requirements.

[0049] In some embodiments, the output port of the die is shaped such that the initial longitudinal structure has a third protrusion extending longitudinally along the radome-molded part, protruding on a straight side region of the radome-molded part, and a fourth protrusion extending longitudinally along the radome-molded part, protruding from the third protrusion. The third protrusion has a third thickness transition portion with machining allowance on both sides, and the fourth protrusion has a fourth thickness transition portion with machining allowance on both sides. Thus, a die of a specific shape can provide another initial longitudinal mechanism suitable for improving the wind load characteristics of the radome, forming a boss-protrusion composite structure.

[0050] In some embodiments, the shape of the die's output opening is configured such that the third protrusion extends along the entire straight side region of the radome-molded part. This allows for the provision of an advantageous initial longitudinal structure suitable for improving the wind load characteristics of the radome through a die of a specific shape.

[0051] In some embodiments, the output port of the die is shaped such that a fourth protrusion is located at the end of the third protrusion, such that a third thickness transition portion of the third protrusion and a fourth thickness transition portion of the fourth protrusion merge at that end of the third protrusion to form a fifth thickness transition portion. Thus, a favorable initial longitudinal structure suitable for improving the wind load characteristics of the radome can be provided by a die of a specific shape.

[0052] In some embodiments, the output port of the die is shaped such that the fourth protrusion is located at the end of the third protrusion near the rear arcuate corner region of the radome-molded part. Thus, a favorable initial longitudinal structure suitable for improving the wind load characteristics of the radome can be provided by a die of a specific shape.

[0053] In some embodiments, the tooling assembly is arranged and configured to machine, with a corresponding individual cylindrical end mill, the remaining third thickness transition of the third protrusion, the remaining fourth thickness transition of the fourth protrusion, and the fifth thickness transition formed by the third thickness transition of the third protrusion and the fourth thickness transition of the fourth protrusion, thereby obtaining the final third and final fourth protrusions to obtain the corresponding final longitudinal structure. Thus, based on an initial longitudinal structure provided by a die suitable for improving the wind load characteristics of the radome, a final longitudinal structure with improved wind load characteristics of the radome is obtained by subtractive machining of the individual thickness transitions of the initial longitudinal structure.

[0054] In some embodiments, the tooling assembly is arranged and configured to machine the third thickness transition portions on both sides of the third protrusion with a single cylindrical end mill to obtain the final third protrusion, and to machine the fourth thickness transition portions on both sides of the fourth protrusion with a combination of two cylindrical end mills and / or two second milling heads of a hob to obtain the final fourth protrusion, thus obtaining the corresponding final longitudinal structure. Thus, based on an initial longitudinal structure suitable for improving the wind load characteristics of the radome provided by the die, a final longitudinal structure with improved wind load characteristics of the radome is obtained by subtractive machining of the respective thickness transition portions of the initial longitudinal structure. Furthermore, cylindrical end mills and / or hobs can be used here as needed, provided that accuracy requirements are met, to satisfy different machining requirements.

[0055] In some embodiments, the reprocessing apparatus includes a first additive processing nozzle positioned in place, configured to apply additive material to the surface of the radome-formed part, thereby forming a final longitudinal structure in conjunction with the pulling motion of a traction device. Thus, a final longitudinal structure of suitable size and shape can be suitably produced using the first additive processing nozzle.

[0056] In some embodiments, the first additive manufacturing nozzle is arranged and configured, or in combination with a die, such that at least two final protrusions extending longitudinally along the radome-molded part are machined on a straight side region of the radome-molded part. These at least two final protrusions include a final first protrusion and a final second protrusion, with the final first protrusion smoothly transitioning to an arcuate corner region of the radome-molded part on one side. Thus, a final longitudinal structure suitable for improving the wind load characteristics of the radome can be machined using a specifically arranged and configured first additive manufacturing nozzle, forming a groove-protrusion composite structure.

[0066] In some embodiments, the machining head, which can rotate around the radome-formed part, can rotate around the radome-formed part along a circular or non-circular trajectory via a rotary mechanism to process the radome-formed part with a circular or non-circular cross-section to form a final helical structure. Thus, suitable machining heads rotating around the radome-formed part along different trajectories can be used for circular or non-circular, such as chamfered rectangular or elliptical radome-formed parts.

[0067] In some embodiments, the rotary mechanism includes a rotary component arranged around the radome-formed part, wherein the rotary component is configured to perform circular rotary motion, and the processing head is fixedly mounted on the rotary component, thereby enabling the processing head to perform circular rotational motion; or the rotary component is configured to perform circular rotary motion, and the processing head is movably mounted on the rotary component in the radial direction, thereby enabling the processing head to perform circular or non-circular rotary motion as needed; or the rotary component is configured to perform non-circular rotary motion, and the processing head is fixedly mounted on the rotary component, thereby enabling the processing head to perform non-circular rotary motion. Thus, different combinations of rotary component and processing head arrangements can be used to allow the processing head, used for machining helical structures, to perform either circular or non-circular rotary motion as needed.

[0068] In some embodiments, the rotating component for performing circular rotational motion is constructed as a hollow annular rotating component. Thus, circular rotational motion can be achieved using a simple and reliable rotating component.

[0069] In some embodiments, the machining head achieves radial mobility along the rotating component through at least one of the following mechanisms:

[0070] - Linear motor drive mechanism;

[0071] - Robotic arm;

[0072] - Gear-rack mechanism;

[0073] - Lead screw mechanism.

[0074] In some embodiments, the rotating component for implementing non-circular rotary motion is constructed as a flexible transmission component, which is capable of cyclic rotary motion within a non-circular guide portion. Thus, non-circular cyclic rotary motion can be suitably achieved using a flexible transmission component.

[0075] In some embodiments, the flexible transmission component is constructed as a chain or belt, especially a synchronous belt.

[0076] In some embodiments, the rotary mechanism further includes a drive gear for driving the rotary component to rotate, and a plurality of spaced-apart openings are provided on the inner and / or outer sides of the circumference of the rotary component, or a plurality of spaced-apart openings are provided through the circumference of the rotary component, wherein the drive gear engages with the openings to drive the rotary component to rotate. Thus, the rotation of the rotary mechanism can be suitably achieved by utilizing the engagement of the drive gear with the openings of the rotary component.

[0077] In some embodiments, the clearance is constructed as a tooth gap, a through hole, or a gap between chains. Thus, different forms of clearance can be used depending on the actual structure that mates with the drive gear.

[0078] In some embodiments, the non-circular trajectory is constructed as an elliptical trajectory or a rectangular trajectory with chamfers, depending on the shape of the radome-molded part. The non-circular trajectory can adopt a corresponding trajectory form according to the actual shape of the radome-molded part.

[0079] In some embodiments, the machining head rotatable around the radome-formed part is configured as a grooving tool, which can machine helical grooves in the surface of the radome-formed part through a combination of rotational motion around the radome-formed part and pulling motion of a traction device. Thus, suitable helical grooves can be machined using the grooving tool through a combination of rotational motion around the radome-formed part and pulling motion of a traction device.

[0080] In some embodiments, the machining head rotatable around the radome-molded part is configured as a second additive machining nozzle, which can machine helical protrusions in the surface of the radome-molded part through rotational motion around the radome-molded part combined with the pulling motion of a traction device. Thus, suitable helical grooves can be machined using the second additive machining nozzle through rotational motion around the radome-molded part combined with the pulling motion of the traction device.

[0081] In some implementations, the slewing mechanism and the traction device work together and are configured to enable the production of a final helical structure with a constant or variable pitch.

[0082] In some embodiments, the ratio of the pitch of the final helical structure to the average diameter of the radome-molded part is 3 to 5. This allows for the fabrication of a final helical structure with a suitable pitch.

[0083] In some embodiments, the molding apparatus further includes a shaping mold disposed downstream of the die and before the cooling device and configured to perform initial shaping of the radome-molded part, the shape of the shaping mold corresponding to the shape of the die, wherein when a reprocessing device is disposed upstream of the cooling device, the reprocessing device is disposed between the shaping mold and the cooling device.

[0112] The molding apparatus for manufacturing a radome according to the present disclosure is first described with reference to FIG1. ​​This molding apparatus is configured to manufacture a radome by pultrusion or extrusion molding. As shown in FIG1, the molding apparatus includes: a die 1 configured to output a radome-molded part 7, the radome-molded part 7 having a longitudinal structure extending in the longitudinal direction; a shaping die 2 disposed downstream of the die 1 and configured to perform initial shaping on the radome-molded part 7; a cooling device 3 disposed downstream of the shaping die 2 and configured to cool the radome-molded part 7; a traction device 4 disposed downstream of the cooling device 3 and configured to pull the radome-molded part 7; and a reprocessing device 5, as shown in FIG1, fixedly disposed downstream of the cooling device 3 and upstream of the traction device 4. The reprocessing apparatus 5 is configured to process the initial longitudinal structure 71 of the radome-molded part 7 through subtractive processing to obtain the final longitudinal structure 72, thereby manufacturing the radome-molded part 7 with the final longitudinal structure 72 (see Figures 2 to 7). In embodiments not shown, the shaping mold 2 may not be provided when the die 1 meets sufficient shape accuracy requirements for the longitudinal structure. Furthermore, in embodiments not shown, the reprocessing apparatus 5 may also be arranged upstream of the cooling device 3, wherein if the shaping mold 2 is provided, the reprocessing apparatus 5 is arranged between the shaping mold 2 and the cooling device 3, and if the shaping mold 2 is not provided, the reprocessing apparatus 5 is arranged between the die 1 and the cooling device 3. For the arrangement of the reprocessing apparatus 5 upstream or downstream of the cooling device 3, the radome-molded part 7 needs to be processed by the reprocessing apparatus 5 while not fully cured. As previously described, suitable softness and hardness of the radome-molded part 7 can be obtained in this incompletely cured state, which is beneficial for "in-line" subtractive processing. In this case, the reprocessing device 5 can be arranged close to the cooling device 3, either upstream or downstream of the cooling device 3.

[0113] In this disclosure, the reprocessing apparatus 5 is configured to produce a final longitudinal structure 72 that can alter the wind load characteristics of the radome-molded part 7 or can be fitted with a corresponding mating structure. The final longitudinal structure 72, extending in the longitudinal direction, can meet corresponding performance requirements, such as wind load characteristics and assembly fit requirements, under different arrangement positions and specific structural shapes.

[0114] As shown in Figure 1, the reprocessing apparatus 5 includes a tool assembly 6. The output opening of the die 1 is shaped such that the initial longitudinal structure 71 has a section where the material thickness changes, wherein the section where the material thickness changes in the initial longitudinal structure 71 includes a thickness transition portion with machining allowance. The tool assembly 6 is arranged and configured to machine at least a portion of the thickness transition portion of the section where the material thickness changes in the initial longitudinal structure 71 of the radome-formed part 7 to obtain the corresponding final longitudinal structure 72. To achieve suitable machining accuracy, as shown in Figure 1, the tool assembly 6 can be at a 90° angle to the machining surface of the radome-formed part 7.

[0115] Some embodiments of the tool assembly 6 are described below with reference to Figures 2 to 8. As shown in Figures 2 to 8, in these embodiments, the tool assembly 6 includes a double-sided tool 62 with two opposing cutting heads, each having two cutting edges 63 and a cutting tip 64. The double-sided tool 62 is configured to simultaneously process two thickness transitions in a section of the initial longitudinal structure 71 where the material thickness changes, to obtain the corresponding final longitudinal structure 72. This double-sided tool 62 is suitable for processing thickness transitions on both sides of a protruding structure—especially those with a smaller width. Here, in the respective cutting heads, the respective two cutting edges 63 are perpendicular to each other, and the respective cutting tips 64 are constructed at right angles. Thus, the right-angled cutting tips 64 can process the corresponding thickness transitions in a section of the initial longitudinal structure 71 where the material thickness changes into at least partially right-angled thickness transitions. For example, an originally inclined thickness transition can be processed into at least partially right-angled thickness transitions by the right-angled cutting tips 64. In another embodiment, the initial thickness transition of this initial longitudinal structure 71 may also have a form different from that of the inclined structure. Furthermore, it can be clearly seen from the corresponding figures that the plane formed by the two cutting edges 63 of the corresponding cutter head is perpendicular to the longitudinal central axis of the radome-formed part 7, thereby achieving a good subtractive machining process.

[0116] In this disclosure, the tool assembly 6 is fixedly arranged, and the radome-formed part 7 moves along the production line under the pull of the traction device 4 and thereby moves relative to the tool assembly 6. Through this relative movement, the tool assembly 6 can perform subtractive processing on the radome-formed part 7.

[0117] Figures 2 through 8 show a double-sided cutting tool 62 with a right-angled cutting tip 64 and its machining method. Besides this type of double-sided cutting tool 62, other forms of double-sided cutting tools 62 can be envisioned to meet different needs. Other forms of double-sided cutting tools 62 are described below with reference to Figures 9 through 12.

[0118] As shown in Figure 9, in some embodiments, in each of the respective blades of the double-sided cutter 62, the two corresponding cutting edges 63 are perpendicular to each other, and the corresponding blade tip 64 is constructed in an outwardly convex arc shape. In this case, the blade tip 64, constructed in an outwardly convex arc shape, can process the corresponding thickness transition portion of the section of the initial longitudinal structure 71 where the material thickness changes into a thickness transition portion that is at least partially concave arc shape.

[0119] As shown in Figure 10, in some embodiments, in each of the respective blades of the double-sided cutter 62, the two corresponding cutting edges 63 are perpendicular to each other, and the corresponding blade tips 64 are constructed at an angle. In this case, the angled blade tips 64 can process the corresponding thickness transitions of the sections of the initial longitudinal structure 71 where the material thickness changes into at least partially angled thickness transitions.

[0120] As shown in Figure 11, in some embodiments, in each of the respective blades of the double-sided cutter 62, the two corresponding cutting edges 63 are perpendicular to each other, and the corresponding blade tip 64 is constructed in a concave arc shape. In this case, the blade tip 64 constructed in a concave arc shape can process the corresponding thickness transition portion of the section of the initial longitudinal structure 71 where the material thickness changes into a thickness transition portion that is at least partially convex arc shape.

[0121] As shown in Figure 12, in some embodiments, in each of the respective blades of the double-sided cutter 62, the two corresponding cutting edges 63 are at acute angles to each other, and the corresponding blade tip 64 is constructed at an acute angle (especially an outwardly convex acute angle). In this case, the blade tip 64, constructed at an acute angle, can process the corresponding thickness transition portion of the section of the initial longitudinal structure 71 where the material thickness changes into a thickness transition portion that is at least partially acute (especially an inwardly concave acute angle).

[0122] In addition to the aforementioned double-sided cutting tool 62, as shown in Figures 13 to 17, the cutting tool assembly 6 may also include a single-sided cutting tool 61. This single-sided cutting tool 61 has a cutting head with two cutting edges 63 and a cutting tip 64. The single-sided cutting tool 61 is configured to machine a thickness transition portion of the initial longitudinal structure 71 where the material thickness changes, to obtain the corresponding final longitudinal structure 72. Similarly, in the cutting head of the single-sided cutting tool 61 shown in Figure 13, the corresponding two cutting edges 63 are perpendicular to each other, and the corresponding cutting tip 64 is constructed at a right angle. In the cutting head of the single-sided cutting tool 61 shown in Figure 14, the corresponding two cutting edges 63 are perpendicular to each other, and the corresponding cutting tip 64 is constructed in an outwardly convex arc shape. In the cutting head of the single-sided cutting tool 61 shown in Figure 15, the corresponding two cutting edges 63 are perpendicular to each other, and the corresponding cutting tip 64 is constructed at an angle. In the cutting head of the single-sided cutting tool 61 shown in Figure 16, the corresponding two cutting edges 63 are perpendicular to each other, and the corresponding cutting tip 64 is constructed in an inwardly concave arc shape. Furthermore, in the cutting head of the single-sided cutting tool 61 shown in Figure 17, the corresponding two cutting edges 63 are at acute angles to each other, and the corresponding cutting tip 64 is constructed at an acute angle (especially an outwardly convex acute angle). The cutting tip 64 of the single-sided cutting tool 61, with its corresponding construction, can also process the corresponding thickness transition portion of the initial longitudinal structure 71 in sections where the material thickness changes into a right angle, a concave arc, an inclined shape, an outwardly convex arc, or an acute angle (especially a concave acute angle) thickness transition portion.

[0123] It should be noted that the combination of the blade 63 and the tip 64 described above is illustrative. To obtain different wind load characteristics, other combinations of blade 63 and other shaped tips 64 can be envisioned in the embodiments not shown. For example, blades 63 at acute angles to each other can be paired with inclined or curved tips 64, which will not be listed here. Furthermore, the thickness transition can be machined by the combined action of the blade 63 and the tip 64, or it can be machined using only the tip 64.

[0124] The following describes, with reference to Figures 18 to 22, some embodiments of forming and processing of the radome-formed part using the die 1 and reprocessing apparatus 5 according to the present disclosure. Figure 18 shows a section of the radome-formed part 7 cut off after the entire processing is completed, serving as the radome. In order to process such a radome-formed part 7, in some embodiments, the shape of the outlet of the die 1 is configured such that an initial longitudinal structure 71 is formed on the side of the radome-formed part 7, and the tool assembly 6 is arranged and configured to process the initial longitudinal structure 71 on the side of the radome-formed part 7. This longitudinal structure on the side of the radome-formed part 7 thus processed can be used in particular to change the wind load characteristics of the radome. Here, in order to obtain more favorable wind load characteristics, the shape of the outlet of the die 1 is configured such that the initial longitudinal structure 71 exiting from the outlet of the die 1 is symmetrically constructed about a central plane on both sides of the radome-formed part 7, and the tool assembly 6 is correspondingly symmetrically arranged about a central plane, wherein the central plane is parallel to the side of the radome-formed part 7 and extends through the center of the radome-formed part 7. Of course, in embodiments not shown, to meet specific wind load characteristics, the shape of the output port of the die 1 can also be configured such that the initial longitudinal structure 71 exiting from the output port of the die 1 is asymmetrically constructed about the central plane on both sides of the radome-formed part 7, and the tool assembly 6 can be correspondingly arranged asymmetrically about the central plane. Besides the side arrangement, it is also conceivable that the shape of the output port of the die 1 is configured such that the initial longitudinal structure 71 is formed on the front side of the radome-formed part 7, and the tool assembly 6 is arranged and configured to machine the initial longitudinal structure 71 on the front side of the radome-formed part 7. This initial longitudinal structure 71 on the front side can also benefit wind load characteristics. Alternatively, it is also conceivable that the shape of the output port of the die 1 is configured such that the initial longitudinal structure 71 is formed on the back side of the radome-formed part 7, and the tool assembly 6 is arranged and configured to machine the initial longitudinal structure 71 on the back side of the radome-formed part 7. This arrangement of the longitudinal structure on the back side can facilitate cooperation with other mating components.

[0125] As can be clearly seen from Figures 20 to 22, the final longitudinal structure forms a groove-protrusion composite structure, which is formed by two protrusions. This final longitudinal structure 72, as shown in Figures 20 to 22, achieves good wind load characteristics. Of course, to obtain this final groove-protrusion composite structure, the initial longitudinal structure 71 of the radome-molded part 7 output from the output port of the die 1 must also form a groove-protrusion composite structure. Therefore, the shape of the output port of the die 1 is configured such that the initial longitudinal structure 71 has at least two protrusions extending along the longitudinal direction of the radome-molded part 7, protruding on the straight side region of the radome-molded part 7. The first protrusion 81 smoothly transitions to the arc-shaped corner region of the radome-molded part 7 on one side and forms a first thickness transition portion with machining allowance on the other side, while the second protrusion 82 forms second thickness transition portions with machining allowance on both sides. In some embodiments, the first protrusion 81 is located near the front side of the radome-molded member 7, and the second protrusion 82 is located near the back side of the radome-molded member 7. Specifically, in the embodiments shown in Figures 20 to 22, the first protrusion 81 is disposed in the front transition region of the radome-molded member 7 where it transitions from a straight side region to a front arcuate corner region, while the second protrusion 82 is disposed near the rear transition region of the radome-molded member 7 where it transitions from a straight side region to a rear arcuate corner region.

[0126] To produce the final longitudinal structure 72 as shown in Figures 20 to 22, the tool assembly 6 is arranged and configured to machine the first thickness transition portion of the first protrusion 81 with a single-sided tool 61 to obtain the final first thickness transition portion 91, and to machine the second thickness transition portions on both sides of the second protrusion 82 with double-sided tools 62 or a combination of two single-sided tools 61 to obtain the final second thickness transition portions 92, thereby obtaining the corresponding final longitudinal structure 72. That is, the single-sided tool 61 of the tool assembly 6 is arranged on the production line at a position corresponding to the first protrusion 81 and machines the first thickness transition portion on one side of the first protrusion 81 under a specific orientation or machining angle, while the double-sided tool 62 or a combination of two single-sided tools 61 of the tool assembly 6 is arranged on the production line at a position corresponding to the second protrusion 82 and machines the second thickness transition portions on both sides of the second protrusion 82 under a specific orientation or machining angle. Here, the corresponding cutting tips 64 of the single-sided cutting tool 61 and / or double-sided cutting tool 62 of the cutting tool assembly 6 are shaped such that the final first thickness transition portion 91 is at least partially constructed at a right angle, and the final second thickness transition portion 92 is also constructed at a right angle. Here, the single-sided cutting tool 61 of the cutting tool assembly 6 can be a single-sided cutting tool 61 with a right-angled cutting tip 64 as described above, and the double-sided cutting tool 62 of the cutting tool assembly 6 can be a double-sided cutting tool 62 with a right-angled cutting tip 64 as described above.

[0127] In addition to machining the final first thickness transition portion 91 and second thickness transition portion 92 with a right angle structure using specific single-sided cutter 61 and / or double-sided cutter 62 of the cutter assembly 6 as shown in Figures 20 to 22, other forms of single-sided cutter 61 and / or double-sided cutter 62 can also be used to machine other forms of the final first thickness transition portion 91 and second thickness transition portion 92. These other forms of the final first thickness transition portion 91 and second thickness transition portion 92 can also achieve good wind load characteristics. As shown in Figures 23 to 26, in different embodiments, the corresponding cutter tip 64 shape of the single-sided cutter 61 and / or double-sided cutter 62 of the cutter assembly 6 can also be configured such that the final first thickness transition portion 91 and second thickness transition portion 92 are respectively (as shown in Figure 23) concave arc-shaped, (as shown in Figure 24) inclined, (as shown in Figure 25) concave arc-shaped, and (as shown in Figure 26) acute angle structured. Therefore, the first thickness transition portion and the second thickness transition portion can be respectively equipped with a single-sided cutting tool 61 and / or a double-sided cutting tool 62 with a cutting head having a concave arc shape (for the embodiment shown in FIG. 23), an inclined shape (for the embodiment shown in FIG. 24), a concave arc shape (for the embodiment shown in FIG. 25), and an acute angle shape (for the embodiment shown in FIG. 26).

[0128] The following describes some other embodiments of forming and processing of the radome molding part according to the die 1 and the reprocessing apparatus 5 according to the present disclosure, with reference to Figures 27 to 29. As can be clearly seen from Figures 27 to 29, the final longitudinal structure forms a boss-protrusion composite structure, which is also formed by two protrusions, one of which is a boss-type protrusion, and the other is constructed on the boss-type protrusion to form a protrusion-type protrusion. This final longitudinal structure 72 shown in Figures 27 to 29 can also achieve good wind load characteristics. Of course, in order to obtain this final groove-protrusion composite structure, the initial longitudinal structure 71 of the radome-molded part 7 output from the output port of the die 1 must also form a groove-protrusion composite structure. Therefore, the shape of the output port of the die 1 is configured such that the initial longitudinal structure 71 has a third protrusion 83 that protrudes from the straight side area of ​​the radome-molded part 7 and extends in the longitudinal direction of the radome-molded part 7, and a fourth protrusion 84 that protrudes from the third protrusion 83 and extends in the longitudinal direction of the radome-molded part 7. The third protrusion 83 has a third thickness transition portion with machining allowance on both sides, and the fourth protrusion 84 has a fourth thickness transition portion with machining allowance on both sides. The fourth protrusion 84 is located at the end of the third protrusion 83 near the rear arc-shaped corner area of ​​the radome-molded part 7, and the fourth protrusion 84 is located at the end of the third protrusion 83. Thus, a third thickness transition portion of the third protrusion 83 and a fourth thickness transition portion of the fourth protrusion 84 merge at the end of the third protrusion 83 to form a fifth thickness transition portion. Here, the shape of the output port of the die 1 is configured such that the third protrusion 83 extends along the entire straight area of ​​the side of the radome-molded part 7.

[0129] To machine the final longitudinal structure 72 as shown in Figures 27 and 28, the tool assembly 6 is arranged and configured to machine the remaining third thickness transition portion of the third protrusion 83, the remaining fourth thickness transition portion of the fourth protrusion 84, and the fifth thickness transition portion formed by the third thickness transition portion of the third protrusion 83 and the fourth thickness transition portion of the fourth protrusion 84, thereby obtaining the final third thickness transition portion 93, the final fourth thickness transition portion 94, and the final fifth thickness transition portion 95, thus obtaining the corresponding final longitudinal structure 72. Here, different single-sided tools 61 can be used for the third thickness transition portion, the fourth thickness transition portion, and the fifth thickness transition portion. Since the fifth thickness transition portion is larger, the size of the cutting tip 64 of the single-sided tool 61 used for the fifth thickness transition portion is larger than the size of the cutting tip 64 of the corresponding single-sided tool 61 used for the third thickness transition portion or the fourth thickness transition portion. In order to machine the corresponding thickness transition portions, the shape of the corresponding cutting tip 64 of the corresponding single-sided cutting tool 61 of the tool assembly 6 is configured such that the final third thickness transition portion 93, fourth thickness transition portion 94 and fifth thickness transition portion 95 are respectively constructed at right angles. Here, the single-sided cutting tool 61 of the tool assembly 6 can be the single-sided cutting tool 61 with the right-angled cutting tip 64 described above.

[0130] In addition to machining the final third thickness transition portion 93, fourth thickness transition portion 94, and fifth thickness transition portion 95 at right angles using a specific single-sided cutter 61 of the cutter assembly 6 as shown in Figures 27 to 29, other forms of single-sided cutters 61 can also be used to machine other forms of the final third thickness transition portion 93, fourth thickness transition portion 94, and fifth thickness transition portion 95. These other forms of the final third thickness transition portion 93, fourth thickness transition portion 94, and fifth thickness transition portion 95 can also achieve good wind load characteristics. As shown in Figures 30 to 33, in different embodiments, the cutting head shape of the corresponding single-sided cutter 61 of the cutter assembly 6 can also be configured such that the final third thickness transition portion 93, fourth thickness transition portion 94, and fifth thickness transition portion 95 are respectively (as shown in Figure 30) concave arc-shaped, (as shown in Figure 31) inclined, (as shown in Figure 32) concave arc-shaped, and (as shown in Figure 33) acute angled. Therefore, for the third thickness transition section, the fourth thickness transition section, and the fifth thickness transition section, a single-sided cutting tool 61 with a cutting head having a concave arc structure (for the embodiment shown in FIG. 30), an inclined structure (for the embodiment shown in FIG. 31), a concave arc structure (for the embodiment shown in FIG. 32), and an acute angle structure (for the embodiment shown in FIG. 33) can be respectively adopted.

[0131] In an embodiment not shown, the tool assembly 6 may also be arranged and configured to machine the third thickness transition portions on both sides of the third protrusion 83 with a single-sided tool 61 to obtain the final third thickness transition portion 93, and to machine the fourth thickness transition portions on both sides of the fourth protrusion 84 with a double-sided tool 62 or a combination of two single-sided tools 61 to obtain the final fourth thickness transition portion 94, thereby obtaining the corresponding final longitudinal structure 72.

[0132] It should be noted that the shape configurations of the various thickness transition portions shown in Figures 20 to 33 are schematic. Each thickness transition portion can have a specific shape individually to meet specific wind load characteristics. That is, thickness transition portions with different shapes can be combined to form the final longitudinal structure 72. Furthermore, for each protrusion, in addition to the arrangement structure mentioned above, it is conceivable that the positions of the first protrusion 81 and the second protrusion 82 can be interchanged. Furthermore, it is conceivable that the fourth protrusion 84 is positioned close to the front of the radome-formed part 7. In some embodiments, the aforementioned cutting head is substantially entirely machined with the cutting tip 64 to form the corresponding final thickness transition portion, thereby making the corresponding final thickness transition portion substantially, for example, substantially arc-shaped or substantially inclined. It is conceivable that in other embodiments, only a portion of the thickness transition portion may be machined with the cutting tip 64, while the remaining thickness transition portion is machined with the cutting edge 63. Furthermore, different final thickness transition portions from the aforementioned embodiments can be machined by combining different types of cutting edges 64 and different shapes of cutting tips 64.

[0133] The following describes a molding method for manufacturing a radome, performed by the molding apparatus according to the present disclosure. The molding method includes the following steps: outputting a radome-molded part and stretching the radome-molded part; outputting the radome-molded part via a die through pultrusion or extrusion molding; the radome-molded part being capable of having a longitudinal structure extending in the longitudinal direction; cooling the radome-molded part; and further processing the radome-molded part, wherein the initial longitudinal structure of the radome-molded part is processed by subtractive processing to obtain a final longitudinal structure, thereby manufacturing a radome-molded part with the final longitudinal structure. The step "further processing the radome-molded part" is performed before or after the step "cooling the radome-molded part." Furthermore, the radome-molded part undergoes initial shaping before cooling. In this molding method, the radome-molded part with the longitudinal structure is output using the die of the molding apparatus according to the present disclosure, and the initial longitudinal structure of the radome-molded part is processed into the final longitudinal structure using the further processing apparatus of the molding apparatus according to the present disclosure.

[0134] Next, some embodiments of the molding apparatus for manufacturing radomes according to the present disclosure are described with reference to Figures 1 and 34. The molding apparatus in these embodiments is configured to manufacture radomes by pultrusion or extrusion molding. As shown in Figure 1, the molding apparatus includes: a die 1 configured to output a radome-molded part 7; a shaping die 2 disposed downstream of the die 1 and configured to initially shape the radome-molded part 7; a cooling device 3 disposed downstream of the shaping die 2 and configured to cool the radome-molded part 7; a traction device 4 disposed downstream of the cooling device 3 and configured to pull the radome-molded part 7; and a reprocessing device 5, as shown in Figure 1, at least partially fixed in position downstream of the cooling device 3 and upstream of the traction device 4. The reprocessing device 5 is configured to perform subtractive processing on the initial longitudinal structure 71 of the radome-molded part 7 produced by the die 1 through its own rotational motion. This allows for the fabrication of the radome-molded part 7 with the final longitudinal structure 72, as shown in Figures 18 to 22, 27, and 28. In embodiments not shown, the shaping mold 2 may be omitted when the die 1 meets sufficient shape accuracy requirements for the longitudinal structure. Furthermore, in embodiments not shown, the reprocessing device 5 may be arranged upstream of the cooling device 3, wherein if the shaping mold 2 is provided, the reprocessing device 5 is arranged between the shaping mold 2 and the cooling device 3; otherwise, the reprocessing device 5 is arranged between the die 1 and the cooling device 3. For the arrangement of the reprocessing device 5 upstream or downstream of the cooling device 3, the radome-molded part 7 needs to be processed by the reprocessing device 5 before complete curing. As previously described, suitable softness and hardness of the radome-molded part 7 can be obtained in this incompletely cured state, which is beneficial for "in-line" subtractive processing. In this case, the reprocessing device 5 can be arranged close to the cooling device 3, upstream or downstream of the cooling device 3.

[0135] As shown in Figure 34, in some embodiments, the reprocessing apparatus 5 may include a rotary tool assembly 6 configured to remove material from the initial longitudinal structure 71 of the radome-formed part 7 by its own rotational motion, thereby performing subtractive processing on the initial longitudinal structure 71 of the radome-formed part 7. Alternatively, the reprocessing apparatus 5 may also include a fixed tool assembly 5, which may include a single-sided tool and / or a double-sided tool, wherein the single-sided tool can process one side of the initial longitudinal structure, while the double-sided tool can process both sides of the initial longitudinal structure simultaneously. The specific structure of the rotary tool assembly 6 will be described below with reference to Figure 34. The structure of the fixed tool assembly 5 can be found in the description of the tool assembly above.

[0136] For subtractive machining of the longitudinal structure, the shape of the output port of the die 1 is configured such that the initial longitudinal structure 71 has a section where the material thickness changes, wherein the section where the material thickness changes in the initial longitudinal structure 71 includes a thickness transition portion with machining allowance. The rotary tool assembly 6 is arranged and configured to machine at least part of the thickness transition portion of the section where the material thickness changes in the initial longitudinal structure 71 of the radome-formed part 7 to obtain the corresponding final longitudinal structure 72.

[0137] To produce this radome-formed part 7, in some embodiments, the output port of the die 1 is shaped such that an initial longitudinal structure 71 is formed on the side of the radome-formed part 7, and the rotary tool assembly 6 is arranged and configured to machine the initial longitudinal structure 71 on the side of the radome-formed part 7. This longitudinal structure on the side of the radome-formed part 7, thus produced, can be used to modify the wind load characteristics of the radome. Here, to obtain more favorable wind load characteristics, the output port of the die 1 is shaped such that the initial longitudinal structure 71 exiting the output port of the die 1 is symmetrically constructed about a central plane on both sides of the radome-formed part 7, and the rotary tool assembly 6 is correspondingly symmetrically arranged about a central plane, which is parallel to the side of the radome-formed part 7 and extends through the center of the radome-formed part 7. Of course, in embodiments not shown, to meet specific wind load characteristics, the shape of the output port of the die 1 can also be configured such that the initial longitudinal structure 71 exiting from the output port of the die 1 is asymmetrically constructed about the central plane on both sides of the radome-formed part 7, and the rotary tool assembly 6 can be correspondingly arranged asymmetrically about the central plane. Besides the side arrangement, it is also conceivable that the shape of the output port of the die 1 is configured such that the initial longitudinal structure 71 is formed on the front side of the radome-formed part 7, and the rotary tool assembly 6 is arranged and configured to machine the initial longitudinal structure 71 on the front side of the radome-formed part 7. This initial longitudinal structure 71 on the front side can also benefit wind load characteristics. Alternatively, it is also conceivable that the shape of the output port of the die 1 is configured such that the initial longitudinal structure 71 is formed on the back side of the radome-formed part 7, and the rotary tool assembly 6 is arranged and configured to machine the initial longitudinal structure 71 on the back side of the radome-formed part 7. This arrangement of the longitudinal structure on the back side can facilitate cooperation with other mating components.

[0138] As can be seen from Figure 34, to machine a groove-protrusion composite structure, the rotary tool assembly 6 may include multiple cylindrical end mills 61 and one hob cutter 62. Each cylindrical end mill 61 has a first milling head 611, which is rotatable about a first milling rotation axis extending perpendicular to the surface of the radome-formed part 7, in order to perform subtractive machining on the initial longitudinal structure 71. The hob cutter 62 has at least one second milling head 612, which is rotatable about a second milling rotation axis extending parallel to the surface of the radome-formed part 7 and orthogonal to the longitudinal axis of the radome-formed part 7, in order to perform subtractive machining on the initial longitudinal structure 71. In addition, as shown in Figure 34, a fixed tool assembly 5 is also present. Therefore, the cylindrical end mills 61 and the hob cutter 62 in the fixed tool assembly 5 and the rotary tool assembly 6 are used in combination. Of course, it is also conceivable to provide only the cylindrical end mills 61 or the hob cutter 62.

[0139] As shown in Figure 34, a single cylindrical end mill 61 can essentially machine one side, while a combination of two cylindrical end mills 61 can machine both sides of a protrusion. These two cylindrical end mills 61 can, for example, be arranged sequentially back and forth along the extension direction of the protrusion, and are positioned on both sides of the protrusion. The hobbing cutter 62 can be equipped with multiple second milling heads 612 as needed; one second milling head 612 can be used to machine one side, while a combination of two second milling heads 612 can machine both sides of the protrusion.

[0140] In some embodiments, the longitudinal structure ultimately obtained by combining the rotary tool assembly 6 with the fixed tool assembly 5 forms a groove-protrusion composite structure, which is formed by two protrusions. As shown in Figures 18 to 22, this configuration, the final longitudinal structure 72 of the groove-protrusion composite structure, achieves good wind load characteristics. To obtain this final groove-protrusion composite structure, the initial longitudinal structure 71 of the radome-molded part 7 output from the output port of the die 1 also forms a groove-protrusion composite structure. For this purpose, the shape of the output port of the die 1 is configured such that the initial longitudinal structure 71 has at least two initial protrusions extending along the longitudinal direction of the radome-molded part 7, protruding on the straight side region of the radome-molded part 7. The first protrusion 81 smoothly transitions to the arcuate corner region of the radome-molded part 7 on one side and forms a first thickness transition portion with machining allowance on the other side, while the second protrusion 82 forms a second thickness transition portion with machining allowance on both sides. In some embodiments, the first protrusion 81 is located near the front side of the radome-molded member 7, and the second protrusion 82 is located near the back side of the radome-molded member 7. Specifically, the first protrusion 81 is disposed in the front transition region of the radome-molded member 7 where it transitions from a straight side region to a front arcuate corner region, while the second protrusion 82 is disposed near the rear transition region of the radome-molded member 7 where it transitions from a straight side region to a rear arcuate corner region.

[0141] To produce the final longitudinal structure 72 shown in Figures 18 to 22, the tool assemblies can be arranged as shown in Figure 34. For the first protrusion 81, it can be machined sequentially along the production line direction using one single-sided tool from the fixed tool assembly 5, one cylindrical end mill 61 from the rotary tool assembly 6, and one second milling head 612 of the hobbing cutter 62 from the rotary tool assembly 6. For the second protrusion 82, it can be machined sequentially along the production line direction using two single-sided tools from the fixed tool assembly 5, two cylindrical end mills 61 from the rotary tool assembly 6, and two second milling heads 612 of the hobbing cutter 62 from the rotary tool assembly 6. The spacing between these corresponding pairs of tools determines the width of the second protrusion 82. Specifically, in the embodiment shown in FIG34, the fixed tool assembly 5 and the rotary tool assembly 6 are arranged and configured to machine the first thickness transition portion of the first protrusion 81 with a single-sided tool, a cylindrical end mill 61 and one of the second milling heads 612 of the hob cutter 62 to obtain the final first protrusion 81, and to machine the second thickness transition portions on both sides of the second protrusion 82 with a combination of two single-sided tools 61, a combination of two cylindrical end mills 61 and a combination of two of the second milling heads 612 of the hob cutter 62 to obtain the final second protrusion 82, thereby obtaining the corresponding final longitudinal structure 72. That is, one single-sided tool of the fixed tool assembly 5 and one of the second milling heads 612 of the cylindrical end mill 61 and hob end mill 62 of the rotary tool assembly 6 are arranged on the production line at a position corresponding to the first protrusion 81 and machine the first thickness transition portion on one side of the first protrusion 81 under a specific orientation or machining angle, such as a vertical angle. Meanwhile, the two single-sided tools of the fixed tool assembly 5 and two of the second milling heads 612 of the cylindrical end mill 61 and hob end mill 62 of the rotary tool assembly 6 are arranged on the production line at a position corresponding to the second protrusion 82 and machine the second thickness transition portions on both sides of the second protrusion 82 under a specific orientation or machining angle, such as a vertical angle. The final longitudinal structure 72 shown in Figures 18 to 22 can be machined by combining the fixed tool assembly 5 and the rotary tool assembly 6. Of course, in other embodiments, it is also conceivable to use only the rotary tool assembly 6 to machine the first protrusion 81 and the second protrusion 82, wherein the first protrusion 81 and the second protrusion 82 can be machined using only the cylindrical milling cutter 61, or only the hobbing cutter 62, or a combination of the cylindrical milling cutter 61 and the hobbing cutter 62.When machining the second protrusion 82 using a cylindrical end mill 61, if the width of the second protrusion 82 to be machined is narrow, causing the upper main body of the two cylindrical end mills 61 to interfere with each other, the two cylindrical end mills 61 can be arranged sequentially and spaced apart from each other along the production line direction.

[0142] In addition to the groove-protrusion composite structure shown in Figures 18 to 22, an antenna radome-molded part 7 with a boss-protrusion composite structure can also be manufactured using molding equipment according to some embodiments of the present disclosure. This boss-protrusion composite structure is also formed by two protrusions, however, one of which is a boss-type protrusion, while the other is constructed on the boss-type protrusion to form a protrusion-type protrusion. To obtain this final boss-protrusion composite structure, the initial longitudinal structure 71 of the antenna radome-molded part 7 output from the output port of the die 1 also needs to form a boss-protrusion composite structure. Therefore, the shape of the output port of the die 1 is configured such that the initial longitudinal structure 71 has a third protrusion 83 that protrudes from the straight side area of ​​the radome-molded part 7 and extends in the longitudinal direction of the radome-molded part 7, and a fourth protrusion 84 that protrudes from the third protrusion 83 and extends in the longitudinal direction of the radome-molded part 7. The third protrusion 83 has a third thickness transition portion with machining allowance on both sides, and the fourth protrusion 84 has a fourth thickness transition portion with machining allowance on both sides. The fourth protrusion 84 is located at the end of the third protrusion 83 near the rear arc-shaped corner area of ​​the radome-molded part 7, and the fourth protrusion 84 is located at the end of the third protrusion 83. Thus, a third thickness transition portion of the third protrusion 83 and a fourth thickness transition portion of the fourth protrusion 84 merge at the end of the third protrusion 83 to form a fifth thickness transition portion. Here, the shape of the output port of the die 1 is configured such that the third protrusion 83 extends along the entire straight area of ​​the side of the radome-molded part 7.

[0143] To machine the final longitudinal structure 72 shown in Figures 27 and 28, in some embodiments, the rotary tool assembly 6 can be arranged and configured to machine the remaining third thickness transition of the third protrusion 83, the remaining fourth thickness transition of the fourth protrusion 84, and the fifth thickness transition formed by the third thickness transition of the third protrusion 83 and the fourth thickness transition of the fourth protrusion 84 together with corresponding cylindrical end mills 61, thereby obtaining the final third protrusion 83 and the fourth protrusion 84, and thus obtaining the corresponding final longitudinal structure 72. Here, different cylindrical end mills 61 can be used for the third thickness transition, the fourth thickness transition, and the fifth thickness transition. In an embodiment not shown, when the fourth protrusion 84 is arranged on the third protrusion 83 in the non-end region of the third protrusion 83, the rotary tool assembly 6 can also be arranged and configured to machine the third thickness transition on both sides of the third protrusion 83 with a combination of two cylindrical end mills 61 or two second milling cutters 612 of a hob cutter 62 to obtain the final third protrusion 83, and to machine the fourth thickness transition on both sides of the fourth protrusion 84 with a combination of another two cylindrical end mills 61 or two additional second milling cutters 612 of another hob cutter 62 to obtain the final fourth protrusion 84, thereby obtaining the corresponding final longitudinal structure 72.

[0144] In alternative embodiments, a combination of rotary tool assembly 6 and fixed tool assembly 5, or a different arrangement of cylindrical end mill 61 and hobbing end mill 62 in rotary tool assembly 6, can be used to machine the final longitudinal structure 72, which is a boss-protrusion composite structure as shown in Figures 27 and 28.

[0145] As shown in Figure 35, in the second embodiment, the reprocessing apparatus can also be configured to perform additive processing on the surface of the radome-molded part 7 to form the final longitudinal structure 72. The reprocessing apparatus may include a first additive processing nozzle 9 with a fixed position, configured to apply additive material to the surface of the radome-molded part 7, thereby forming the final longitudinal structure 72 in conjunction with the pulling motion of the traction device 4. The first additive processing nozzle 9 may be arranged upstream of the cooling device 3 along the production line direction, particularly between the forming mold 2 and the cooling device 3. In the second embodiment, since subtractive processing is not performed on the radome-molded part 7, the die 1 can be configured to form a smooth-surfaced radome-molded part 7 without protrusions. The first additive processing nozzle 9 can then perform additive processing on the surface of the radome-molded part 7. In other aspects, the arrangement of the second embodiment of the molding equipment can be found in the corresponding description of some embodiments of the molding equipment.

[0146] To produce the final longitudinal structure 72, which is a groove-protrusion composite structure as shown in Figures 18 to 22, the first additive manufacturing nozzle 9 can be arranged and configured such that at least two final protrusions extending longitudinally along the radome-molded part 7 are formed on the straight side region of the radome-molded part 7. These at least two final protrusions include a final first protrusion 81 and a final second protrusion 82, with the final first protrusion 81 smoothly transitioning to the arcuate corner region of the radome-molded part 7 on one side. Alternatively, it is conceivable that an initial longitudinal structure is first formed using the die 1, and then the corresponding side portions of the initial first protrusion 81 and the second protrusion in the initial longitudinal structure are additively processed using the first additive manufacturing nozzle 9 to produce the final longitudinal structure 72. Here, the first additive manufacturing nozzle 9 is arranged and configured such that the final first protrusion 81 is close to the front of the radome-molded part 7; and / or the final second protrusion is close to the back of the radome-molded part 7; and / or the final first protrusion 81 is located in the front transition region of the radome-molded part 7 where it transitions from the side straight region to the front arc corner region, while the final second protrusion is located in the rear transition region of the radome-molded part 7 where it transitions from the side straight region to the rear arc corner region.

[0147] Alternatively, it is conceivable that the first additive manufacturing nozzle 9 is arranged and configured such that a third protrusion 83 extending longitudinally along the radome-molded part 7 and a fourth protrusion 84 extending longitudinally along the radome-molded part 7 are formed on the straight side region of the radome-molded part 7, thereby producing the final longitudinal structure 72 with a boss-protrusion composite structure as shown in Figures 27 and 28. It is also conceivable that an initial longitudinal structure is first formed using the die 1, and then the corresponding side portions of the initial third protrusion 83 and fourth protrusion 84 in the initial longitudinal structure are additively processed using the first additive manufacturing nozzle 9 to produce the final longitudinal structure 72. Here, the first additive manufacturing nozzle 9 can be arranged and configured such that the third protrusion 83 extends over the entire straight area of ​​the side of the radome-molded part 7; and / or the fourth protrusion 84 is disposed at the end of the third protrusion 83; and / or the fourth protrusion 84 is disposed at the end of the third protrusion 83 near the rear arcuate corner area of ​​the radome-molded part 7.

[0148] Next, further embodiments of the molding apparatus of this disclosure will be described with reference to Figures 36 to 38. The molding apparatus in these further embodiments includes a processing head rotatable about a radome-molded part 7, the processing head being configured to perform subtractive or additive machining on the surface of the radome-molded part 7 while rotating around it, in combination with the pulling motion of the traction device 4 to form a final helical structure 11. The processing head rotatable about the radome-molded part 7 is configured as a grooving tool 10, which is capable of forming helical grooves in the surface of the radome-molded part 7 by combining the rotational motion around it with the pulling motion of the traction device 4. As shown in Figures 37 and 38, the processing head rotatable about the radome-molded part 7 can rotate around it along a circular trajectory via a rotary mechanism to process the radome-molded part 7, which has a circular cross-section, to form the final helical structure 11. The rotary mechanism includes a rotary component 12 arranged around the radome-formed part 7. The rotary component 12 is configured to perform circular rotary motion, and a machining head, configured as a grooving tool 10, is fixedly mounted on the rotary component 12. This allows the machining head to perform circular rotational motion, thereby performing subtractive machining on the radome-formed part 7. Combined with the pulling motion of a pulling device, a spiral groove structure is ultimately machined. Here, the rotary component 12 for performing circular rotary motion is configured as a hollow annular rotary component 12. Furthermore, the rotary mechanism includes a drive gear 13 for driving the rotary component 12 to rotate, and a plurality of spaced-apart gaps are provided on the outer periphery of the rotary component 12. The drive gear 13 engages in these gaps to drive the rotary component 12 to rotate. This drive gear 13 can be driven, for example, by an electric motor. Here, a toothed structure is provided on the outer periphery of the rotary component 12, and the gaps are configured with tooth gaps 14. For the open section, it is also possible to imagine multiple through holes spaced apart from each other, and pins can be arranged between each through hole as a transmission structure.

[0149] In embodiments not shown, the machining head, configured as a grooving tool 10, which is rotatable around the radome-formed part 7, can also rotate around the radome-formed part 7 via a rotary mechanism along a non-circular trajectory, such as an elliptical trajectory or a chamfered rectangular trajectory, to machine the radome-formed part 7 with a non-circular, elliptical, or chamfered rectangular cross-section to form a final helical groove structure. For this purpose, the rotary mechanism includes a rotary member 12 arranged around the radome-formed part 7, configured to perform circular rotary motion, and the machining head is movably disposed on the rotary member 12 in the radial direction, so that the machining head can perform non-circular rotary motion as needed; or the rotary member 12 is configured to perform non-circular rotary motion, and the machining head is fixedly disposed on the rotary member 12, so that the machining head can perform non-circular rotary motion. The rotary member 12 for performing circular rotary motion can also be configured as a hollow annular rotary member 12. Here, the machining head achieves radial mobility along the rotating component 12 through at least one of the following mechanisms: a linear motor drive mechanism; a robotic arm; a gear-rack mechanism; or a lead screw mechanism. The rotating component 12, used to perform non-circular rotary motion, can be configured as a flexible transmission component capable of cyclic rotary motion within a non-circular guide section. The flexible transmission component is configured as a chain or belt, particularly a synchronous belt. Here, a drive gear 13 can also be provided to drive the rotating component 12 in rotary motion. The chain can be rotated via the drive gear 13. For the belt, teeth can be provided as gaps, or through holes can be provided. Therefore, depending on the specific structure, the gaps can be configured as tooth gaps, through holes, or gaps between chains.

See also the arrangement of the molding equipment in the second embodiment for other aspects.

[0151] Further embodiments of the molding apparatus of this disclosure are described below with reference to FIG. 39. In these further embodiments, the processing head rotatable about the radome-molded part 7 can be configured as a second additive processing nozzle 15, which can form helical protrusions in the surface of the radome-molded part 7 by a combination of rotational movement about the radome-molded part 7 and pulling movement of the traction device 4.

Therefore, reference can be made to the relevant description of the other embodiments regarding aspects relating to the form of movement of the processing head and the related implementation mechanism. The second additive processing nozzle 15 can be arranged upstream of the cooling device 3, so that the applied material can be solidified in the cooling device 3 after additive processing.

[0152] Here, the slewing mechanism and the traction device 4 work together and are configured to form a final helical structure 11 with a constant or variable pitch. The ratio of the pitch of the final helical structure 11 to the average diameter of the radome-formed part 7 is 3 to 5.

[0153] In this disclosure, the reprocessing apparatus is configured to cooperate with the pulling motion of the traction device 4 to form a final longitudinal structure 72 and / or a final helical structure 11, which can change the wind load characteristics of the radome-formed part 7 or can cooperate with corresponding mating structures. The final longitudinal structure 72 and the final helical structure 11 can meet corresponding performance requirements, such as wind load characteristics and assembly requirements, under different arrangement positions and specific structural shapes.

[0154] Finally, a molding method for manufacturing a radome is described, which is performed by the molding apparatus according to the present disclosure. The molding method includes the following steps: outputting a radome-molded part and stretching the radome-molded part; outputting the radome-molded part via a die through pultrusion or extrusion molding; cooling the radome-molded part; and performing subtractive processing on the initial longitudinal structure of the radome-molded part or additive processing on the surface of the radome-molded part by means of a fixed-position reprocessing device through its rotational motion to form a final longitudinal structure; and / or performing subtractive or additive processing on the surface of the radome-molded part by means of a processing head rotatable around the radome-molded part while rotating around the radome-molded part, to form a final helical structure in conjunction with the stretching motion of the traction device. In the case of subtractive processing, the step "reprocessing the radome-molded part" is performed before or after the step "cooling the radome-molded part"; in the case of additive processing, the step "reprocessing the radome-molded part" is performed before the step "cooling the radome-molded part". In addition, the radome-molded part is initially shaped before cooling.
