Description

Technical Field

[0001] This invention relates to the field of tapered roller technology, specifically to a mechanism and method for forming a radome workpiece roll plate. Background Technology

[0002] A tapering machine is a specialized piece of equipment used for rolling and shaping metal sheets or other sheet materials, or for surface treatment. It is widely used in machinery manufacturing, automotive industry, aerospace, and architectural decoration, and is particularly valuable in the processing of radome workpieces. A traditional tapering machine typically includes a frame, upper and lower rollers, a drive unit, and a clamping mechanism. The relative rotation of the upper and lower rollers drives the sheet material to move and complete the rolling process.

[0003] In existing tapering machines, the power transmission chain needs to be disconnected or a complex electromagnetic clutch mechanism needs to be used when adjusting the roller gap by raising and lowering the upper roller. This results in cumbersome operation and is prone to power connection problems, affecting the continuity of processing. During the tapering process of sheet metal, friction powder needs to be supplied to the processing area to reduce frictional resistance, lower processing temperature and improve surface quality. However, existing equipment mostly uses manual powder application or fixed flow supply, which cannot automatically adjust the amount of powder according to the processing conditions, resulting in powder waste or insufficient supply, which affects the processing quality. The transmission connection between the upper and lower rollers is prone to jamming or unstable transmission when the roller gap changes. Summary of the Invention

[0004] This application provides a radar dome workpiece roll forming mechanism and method, the main purpose of which is to achieve three-roll synchronous transmission under single motor drive, continuous transmission when the roller spacing is adjusted, and adaptive matching of friction powder supply.

[0005] To achieve the above objectives, a first aspect of this application provides a single-motor fully driven cone reel with displacement adaptive processing function, including a base and a processing box; and further including:

[0006] A drive motor is disposed inside the processing box;

[0007] An upper conical roller is rotatably disposed outside the processing box;

[0008] The lower conical roller is rotatably disposed outside the processing box and cooperates with the upper conical roller to form a processing gap for processing the sheet metal;

[0009] A hydraulic lifting mechanism is provided above the processing box and connected to the upper conical roller. The mechanism is used to drive the upper conical roller to move up and down to adjust the roller spacing between the upper and lower conical rollers.

[0010] A transmission assembly, which is connected to the drive motor and the upper conical roller, is used to maintain the continuity of the transmission connection when the hydraulic lifting mechanism adjusts the roller spacing;

[0011] A friction powder supply mechanism, which is mounted on the processing box, is used to supply friction powder to the surface of the plate.

[0012] The friction powder supply mechanism includes a release amount adjustment component, which is mechanically linked to the hydraulic lifting mechanism to automatically adjust the output amount of friction powder according to the change in the roller spacing.

[0013] In one feasible implementation, the transmission assembly includes an intermediate transmission assembly and a displaceable transmission assembly. The intermediate transmission assembly includes a multi-output transmission box, a first universal joint drive component, and a longitudinal transmission assembly slot. The multi-output transmission box is connected to the output shaft of the drive motor. The multi-output transmission box has at least three power output ends, two of which are connected to the two lower tapered rollers respectively via the first universal joint drive component. The longitudinal transmission assembly slot is disposed on the third power output end of the multi-output transmission box.

[0014] In one feasible implementation, the displaceable transmission assembly includes a polygonal power input shaft and a second universal joint drive component. The polygonal power input shaft is a hexagonal shaft. One end of the polygonal power input shaft is slidably inserted into the longitudinal transmission assembly groove, and the other end is connected to the input end of the upper conical roller through the second universal joint drive component, so that the polygonal power input shaft can slide axially while transmitting torque to compensate for the displacement of the upper conical roller.

[0015] In one feasible implementation, the multi-output transmission box also forms a fourth power output terminal, which is connected to a pressure generating mechanism. The pressure generating mechanism includes an air pump head, an air inlet, and an exhaust port. The input end of the air pump head is connected to the fourth power output terminal or the output end of the drive motor. The air pump head draws in outside air through the air inlet and discharges compressed air through the exhaust port, providing pneumatic power for the delivery of friction powder.

[0016] In one feasible embodiment, the friction powder supply mechanism includes a storage box, a powder output pipe, and a release mechanism. The top of the storage box is sealed with a lid, the bottom of the storage box is connected to the release mechanism through the powder output pipe, the storage box is fixed inside the processing box by a support frame, and an air inlet filter is provided on the top of the storage box.

[0017] In one feasible implementation, the release adjustment assembly includes a lifting beam, a horizontal moving rod, an adjustment hole, an inclined connecting rod, and a fastening seat. The lifting beam is vertically arranged and its top end is fixedly connected to the lifting block of the hydraulic lifting mechanism. The horizontal moving rod is horizontally fixed to the bottom of the lifting beam. The adjustment hole is provided with a gradually changing diameter along the length direction of the horizontal moving rod and is opened through the end of the horizontal moving rod. The upper end of the inclined connecting rod is hinged to the end of the horizontal moving rod away from the adjustment hole, and the lower end is hinged to the lifting beam. The fastening seat is fixedly sleeved on the outside of the inlet of the powder output pipe. When the lifting beam moves up and down with the lifting block, the inclined connecting rod drives the horizontal moving rod to slide back and forth in a direction perpendicular to the powder output pipe, thereby changing the overlapping area of ​​the adjustment hole and the powder output pipe.

[0018] In one feasible embodiment, the release mechanism includes release rods and release nozzles. Both release rods are hollow tubular structures. The release rods extend outside the processing box and face the feed contact sides of the upper and lower cone rollers with the plate, respectively. Multiple release nozzles are evenly distributed along the length of the release rods. The release nozzles are atomizing nozzles. The release rods are connected to the outlet of the powder output pipe, so that the friction powder is evenly sprayed onto the surface of the plate through the release nozzles.

[0019] In one feasible embodiment, the hydraulic lifting mechanism includes a hydraulic cylinder, a connecting member, and a lifting block. The hydraulic cylinder is vertically disposed on the top of the processing box, and the output end of the hydraulic cylinder extends downward and is fixedly connected to the lifting block through the connecting member. The upper conical roller is rotatably disposed inside the lifting block. The side wall of the lifting block is provided with a guide groove, and the inner walls of both sides of the processing box are vertically provided with guide rods. The guide rods slide in cooperation with the guide grooves to limit the movement trajectory of the lifting block and prevent the lifting block from deviating during the lifting process.

[0020] In one feasible implementation, there are two lower conical rollers, which are symmetrically arranged on the lower outer side of the processing box. The upper conical roller is arranged above the two lower conical rollers and between them. The three rollers cooperate to form a three-roller conical forming area.

[0021] A processing method for a radar dome workpiece rolling forming mechanism, applied to the aforementioned radar dome workpiece rolling forming mechanism, includes the following steps:

[0022] S1. Feed the sheet material to be processed into the three-roll conical forming area formed by the upper conical roller and the two lower conical rollers; according to the thickness of the sheet material, start the hydraulic lifting mechanism, drive the lifting block to move up and down along the guide groove through the hydraulic cylinder, and drive the upper conical roller to move to adjust to the appropriate roller spacing.

[0023] S2. In step S1, while the lifting block is displaced, the lifting block drives the lifting beam of the release amount adjustment component to move up and down synchronously. The displacement of the lifting beam is converted into the sliding of the transverse rod along the direction perpendicular to the powder output pipe through the tilting link, which mechanically changes the overlapping cross-sectional area of ​​the adjustment hole and the powder output pipe: when the plate is thicker and the upper cone roller is raised higher, the overlapping cross-sectional area is larger, and vice versa, thus completing the adaptive pre-adjustment of the friction powder output cross-section.

[0024] S3. Start the drive motor, and its power input is distributed to the multi-output transmission box: three power paths are transmitted to the lower cone roller and the upper cone roller respectively through the first cross universal transmission component and the displacement transmission component, driving the cone roller to rotate and roll the board; at the same time, the fourth power path of the multi-output transmission box synchronously drives the air pump head of the air pressure generating mechanism to operate, drawing in outside air and outputting it to the surface of the board through the powder output pipe.

[0025] This application provides a radome workpiece rolling forming mechanism and method. The radome workpiece rolling forming mechanism employs single-motor full-drive technology. A multi-output transmission box distributes the power of the drive motor to multiple output ends, achieving synchronous drive of the upper conical roller and two lower conical rollers. This ensures consistent linear speed of the three rollers and prevents slippage or stretching deformation of the sheet metal during processing. Simultaneously, the polygonal power input shaft of the displaceable transmission component, in conjunction with the longitudinal transmission assembly groove, achieves variable center distance transmission. The polygonal power input shaft can slide axially while transmitting torque, adapting to changes in center distance during the lifting and lowering of the upper conical roller, ensuring smooth and uninterrupted transmission. The structure is compact and the transmission is reliable. Combined with the multi-link linkage structure of the release adjustment component, friction is achieved... The adaptive adjustment of powder supply, with the lifting beam, transverse rod, and tilting linkage forming a linkage mechanism, converts the lifting displacement of the upper conical roller into a change in the overlapping area of ​​the adjustment hole and the powder output pipe, achieving matching of friction powder flow rate with the thickness of the sheet material, and avoiding powder waste or insufficient supply affecting processing quality. In addition, the pneumatic conveying mechanism is connected to the fourth power output end of the multi-output transmission box through the air pressure generation mechanism, realizing pneumatic conveying of friction powder. When the drive motor is running, it synchronously drives the air pump head to work, generating compressed air which is conveyed to the Venturi tube through the conveying pipe. The Venturi tube uses the Venturi effect to generate negative pressure to draw in the friction powder and mix and convey it, avoiding powder blockage or poor conveying. The overall structure is compact and simple, and the operation mechanism is reliable and smooth, meeting the processing conditions of sheets of different thicknesses. Attached Figure Description

It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0038] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element. The term "two or more" includes two or more cases.

[0039] Please see Figures 1 to 10 As shown, in a first aspect, the present invention provides a radar dome workpiece roll forming mechanism, including a base 10 and a processing box 20; it also includes: a drive motor 21, an upper conical roller 50, a lower conical roller 60, a hydraulic lifting mechanism 40, a transmission assembly, and a friction powder supply mechanism 30.

[0040] Specifically, the drive motor 21 is located inside the processing box 20, providing power to the entire machine. The upper conical roller 50 is rotatably mounted outside the processing box 20. The lower conical roller 60 is rotatably mounted outside the processing box 20, cooperating with the upper conical roller 50 to form a processing gap for processing the sheet material 80. The hydraulic lifting mechanism 40 is located above the processing box 20 and connected to the upper conical roller 50, used to drive the upper conical roller 50 up and down to adjust the roller spacing between the upper and lower conical rollers 60. The transmission assembly is connected to the drive motor 21 and the upper conical roller 50, maintaining the continuity of the transmission connection when the hydraulic lifting mechanism 40 adjusts the roller spacing. The friction powder supply mechanism 30 is located on the processing box 20, used to supply friction powder to the surface of the sheet material 80. The friction powder supply mechanism 30 includes a release amount adjustment component 36, which is mechanically linked to the hydraulic lifting mechanism 40, automatically adjusting the output amount of friction powder according to changes in the roller spacing.

[0041] This embodiment discloses the core structure of a radar dome workpiece rolling forming mechanism. Its purpose is to achieve synchronous transmission of three rollers under a single motor drive, adaptive adjustment of the roller spacing, and automatic matching of the friction powder supply. Specifically, the roller spacing is adjusted by driving the upper conical roller 50 up and down via a hydraulic lifting mechanism 40 to accommodate the processing requirements of plates 80 of different thicknesses. Simultaneously, the transmission assembly maintains continuous transmission connection during the displacement of the upper conical roller 50, ensuring uninterrupted power transmission. As the roller spacing changes, the release amount adjustment component 36 automatically adjusts the friction powder output through a purely mechanical linkage, achieving adaptive matching between processing conditions and lubrication supply. This avoids waste or insufficient supply of friction powder, which could cause slippage in thicker metal plates with stronger anti-bending capabilities during rolling, affecting processing quality.

[0042] Please see Figure 2 , Figure 9 As shown, in some examples, the transmission assembly further includes an intermediate transmission assembly 22 and a displaceable transmission assembly 24. The intermediate transmission assembly 22 includes a multi-output transmission box 221, a first universal joint 222, and a longitudinal transmission assembly slot 223. The multi-output transmission box 221 is connected to the output shaft of the drive motor 21. The multi-output transmission box 221 has at least three power output ends, two of which are connected to two lower tapered rollers 60 respectively through the first universal joint 222. The longitudinal transmission assembly slot 223 is provided on the third power output end of the multi-output transmission box 221.

[0043] This example further specifies the internal structure and power distribution mechanism of the intermediate transmission assembly 22. In the specific implementation of the scheme, the multi-output transmission box 221 adopts a gear transmission structure to distribute the power input from the drive motor 21 to multiple output ends. The two outputs of the first cross universal joint transmission component 222 are respectively connected to the two lower conical rollers 60 to realize synchronous and same-speed drive of the two lower conical rollers. The longitudinal transmission assembly groove 223 extends vertically to form the installation and sliding space of the displaceable transmission assembly 24. The third power output end of the multi-output transmission box 221 is connected to the longitudinal transmission assembly groove 223 to transmit power to the upper conical roller 50. When the hydraulic lifting mechanism 40 drives the upper conical roller 50 to move up and down, the displaceable transmission assembly 24 slides in the longitudinal transmission assembly groove 223 to compensate for changes and achieve a sliding transmission effect, thereby ensuring smooth and non-jamming transmission, and maintaining synchronous transmission function after position change.

[0044] Please see Figure 6 , Figure 9As shown, in some examples, the displaceable transmission assembly 24 further includes a polygonal power input shaft 241 and a second universal joint 242. The polygonal power input shaft 241 is a hexagonal shaft. One end of the polygonal power input shaft 241 is slidably inserted into the longitudinal transmission assembly groove 223, and the other end is connected to the input end of the upper tapered roller 50 through the second universal joint 242, so that the polygonal power input shaft 241 can slide axially to compensate for the displacement of the upper tapered roller 50 while transmitting torque.

[0045] This example further specifies the structure and displacement compensation mechanism of the displaceable transmission component 24. In the specific implementation of the scheme, the polygonal power input shaft 241 adopts a hexagonal cross-section structure and is inserted into the hexagonal mating groove of the longitudinal transmission assembly groove 223. The mating of the hexagonal shaft and the hexagonal groove allows axial sliding while transmitting torque, realizing axial displacement compensation. The second universal joint transmission component 242 adopts a universal joint structure with a cross shaft, including a cross shaft, bearing housing and connecting flange, which can transmit torque within a certain angle range and compensate for axial and angular deviations. When the hydraulic lifting mechanism 40 drives the upper conical roller 50 to move up and down, the polygonal power input shaft 241 slides axially in the longitudinal transmission assembly groove 223, while the second universal joint transmission component 242 compensates for angular deviations, realizing continuous power transmission during the displacement process of the upper conical roller 50, thereby avoiding transmission interruption or jamming and ensuring processing continuity.

[0046] Please see Figure 9 As shown, in some examples, the multi-output transmission box 221 further includes a fourth power output terminal, which is connected to a pressure generating mechanism 23. The pressure generating mechanism 23 includes an air pump head 231, an air inlet 232, and an exhaust port 233. The input end of the air pump head 231 is connected to the fourth power output terminal. The air pump head 231 draws in outside air through the air inlet 232 and discharges compressed air through the exhaust port 233, providing pneumatic power for the delivery of friction powder.

[0047] This example further specifies the driving method and air circuit structure of the air pressure generating mechanism 23. In the specific implementation of the scheme, the fourth power output end of the multi-output transmission box 221 is connected to the input end of the air pump head 231 through a transmission shaft or coupling, and the air pump head 231 is driven to work synchronously when the drive motor 21 is running. A piston or diaphragm is provided inside the air pump head 231, and the piston or diaphragm reciprocates under the drive of the fourth power output end. The air inlet 232 is connected to the outside atmosphere and is equipped with a one-way valve, which only allows air to enter the air pump head 231. The exhaust port 233 is connected to the venturi tube 235 through the delivery pipe 234. When the drive motor 21 starts, the air pump head 231 operates synchronously, drawing in outside air through the air inlet 232 and compressing it, and outputting compressed air from the exhaust port 233. The compressed air is transported to the Venturi tube 235 through the delivery pipe 234, and the negative pressure generated by the Venturi effect is used to draw in the friction powder and mix and transport it, so as to realize the pneumatic transport of the friction powder and ensure a stable supply.

[0048] Please see Figure 4 and Figure 5 As shown, in some examples, the friction powder supply mechanism 30 further includes a storage tank 31, a powder output pipe 35, a release mechanism 70, a delivery pipe 234, and a venturi tube 235. The top of the storage tank 31 is sealed with a cover 32. The bottom of the storage tank 31 is connected to the release mechanism 70 through the powder output pipe 35. The exhaust port 233 is connected to the venturi tube 235 through the delivery pipe 234. The venturi tube 235 is connected to the powder output pipe 35. The storage tank 31 is fixed inside the processing tank 20 by a support frame 34. An air inlet filter 33 is provided on the top of the storage tank 31.

[0049] This example further specifies the overall structure of the friction powder supply mechanism 30 and the powder conveying method. In the specific implementation of the scheme, the storage tank 31 is made of metal or plastic and has sufficient capacity to store the friction powder. The friction powder can be graphite powder, talc powder, molybdenum disulfide, or other powder materials with lubricating and friction-reducing effects. The cover 32 is placed on the top of the storage tank 31 for easy feeding and sealing, and is designed to be detachable or hinged for easy opening and feeding. The air inlet filter 33 is set on the top of the storage tank 31 to balance the air pressure inside and outside the storage tank 31, and at the same time prevent impurities and dust from entering the storage tank 31 and contaminating the powder. The support frame 34 is used to fix the storage tank 31 inside the processing tank 20, and is fixed by welding or bolt connection. The compressed air output from the exhaust port 233 is delivered to the venturi tube 235 via the delivery pipe 234. The venturi tube 235 uses the venturi effect to generate negative pressure, which draws in the friction powder at the bottom of the storage box 31 and mixes it with the airflow. The mixture is then delivered to the release mechanism 70 via the powder output pipe 35, thereby realizing the pneumatic delivery of the friction powder and avoiding powder blockage or poor delivery.

[0050] Please see Figure 6 As shown, in some examples, the release adjustment assembly 36 further includes a lifting beam 361, a transverse rod 362, an adjustment hole 363, an inclined connecting rod 364, and a fastening seat 365. The lifting beam 361 is vertically arranged and its top end is fixedly connected to the lifting block 43 of the hydraulic lifting mechanism 40. The transverse rod 362 is horizontally fixed to the bottom of the lifting beam 361. The adjustment hole 363 is provided with a gradually changing diameter along the length direction of the transverse rod 362 and is opened through the end of the transverse rod 362. The upper end of the inclined connecting rod 364 is hinged to the end of the transverse rod 362 away from the adjustment hole 363, and the lower end is hinged to the lifting beam 361. The fastening seat 365 is fixedly sleeved on the outside of the inlet of the powder output pipe 35. When the lifting beam 361 moves up and down with the lifting block 43, the inclined connecting rod 364 drives the transverse rod 362 to slide back and forth in a direction perpendicular to the powder output pipe 35, thereby changing the overlapping area of ​​the adjustment hole 363 and the powder output pipe 35.

[0051] This example further specifies the multi-link linkage structure and flow regulation mechanism of the release volume adjustment component 36. In the specific implementation of the scheme, the lifting beam 361 is vertically set, with its top end fixedly connected to the lifting block 43, and moves up and down synchronously with the lifting block 43. The horizontal moving rod 362 is horizontally fixed to the bottom of the lifting beam 361, and the diameter of the adjusting hole 363 gradually changes along the length direction of the horizontal moving rod 362, that is, the diameter of the adjusting hole 363 gradually increases or decreases from one end to the other. The upper end of the inclined connecting rod 364 is hinged to the end of the horizontal moving rod 362 away from the adjusting hole 363, and the lower end is hinged to the lifting beam 361, forming a reversing push-pull structure. The fastening seat 365 is fixedly sleeved on the outside of the inlet of the powder output pipe 35, and the outlet of the powder output pipe 35 is correspondingly set with the adjusting hole 363. When the hydraulic lifting mechanism 40 drives the upper conical roller 50 to rise to process thicker plates 80, the lifting block 43 rises, causing the lifting beam 361 to rise. Through the pushing and pulling action of the inclined connecting rod 364, the transverse rod 362 slides along a direction perpendicular to the powder output pipe 35, increasing the overlap area between the adjusting hole 363 and the powder output pipe 35, thus increasing the friction powder flow rate. Conversely, when processing thinner plates 80, the overlap area decreases, and the friction powder flow rate decreases. Through the gradual diameter design of the adjusting hole 363 and the coordination of the transverse rod 362's displacement, the friction powder output cross-section is adaptively adjusted, thereby matching the friction powder flow rate with the plate thickness and avoiding powder waste or insufficient supply.

[0052] Please see Figure 7As shown, in some examples, the release mechanism 70 further includes a release support rod 71 and a release nozzle 72. Both release support rods 71 ​​are hollow tubular structures. The release support rods 71 ​​extend outside the processing box 20 and face the feed contact side of the upper cone roller 50 and the lower cone roller 60 with the plate 80, respectively. Multiple release nozzles 72 are evenly distributed along the length of the release support rod 71. The release nozzles 72 are atomizing nozzles. The release support rod 71 is connected to the outlet of the powder output pipe 35, so that the friction powder is evenly sprayed onto both surfaces of the plate 80 through the two release nozzles 72.

[0053] This example further specifies the structure of the release mechanism 70 and the method of releasing the friction powder. In the specific implementation of the scheme, both release supports 71 are hollow tubular structures made of metal or plastic tubing. The release supports 71 extend outside the processing box 20 and face the feed contact side of the upper conical roller 50 and lower conical roller 60 with the plate 80, respectively, ensuring that the friction powder can be sprayed onto the contact area between the plate 80 and the roller surface. Multiple release nozzles 72 are evenly distributed along the length of the release supports 71. The release nozzles 72 are atomizing nozzles that mix the friction powder with compressed air and then atomize it, so that the friction powder is evenly distributed on the surface of the plate 80. The release supports 71 are connected to the outlet of the powder output pipe 35. Compressed air pushes the friction powder through the release supports 71 and sprays it out from the release nozzles 72. Through the even distribution and atomization of multiple nozzles, the friction powder is evenly covered on the surface of the plate 80, thereby reducing frictional resistance, lowering the processing temperature, and improving the surface quality and tapering accuracy of the plate.

[0054] Please see Figure 2 , Figure 6 As shown, in some examples, the hydraulic lifting mechanism 40 further includes a hydraulic cylinder 41, a connecting member 42, and a lifting block 43. The hydraulic cylinder 41 is vertically mounted on the top of the processing box 20. The output end of the hydraulic cylinder 41 extends downward and is fixedly connected to the lifting block 43 through the connecting member 42. The upper conical roller 50 is rotatably mounted inside the lifting block 43. The side wall of the lifting block 43 is provided with a guide groove. The inner walls of both sides of the processing box 20 are vertically provided with guide rods. The guide rods slide in cooperation with the guide grooves to limit the movement trajectory of the lifting block 43 and prevent the lifting block 43 from deviating during the lifting process.

[0055] This example further specifies the structure and guiding and limiting mechanism of the hydraulic lifting mechanism 40. In the specific implementation of the scheme, the hydraulic cylinder 41 is vertically installed on the top of the processing box 20, and a single-acting or double-acting hydraulic cylinder is used. The hydraulic cylinder 41 is supplied with pressurized oil through an external hydraulic station or a manual hydraulic pump. One end of the connecting piece 42 is connected to the output end of the hydraulic cylinder 41, and the other end is fixedly connected to the lifting block 43. The lifting block 43 is a block-shaped or plate-shaped structure, and the roller shaft of the upper conical roller 50 is rotatably connected to the lifting block 43 through bearings to achieve relative rotation. The guide groove is set on the side wall of the lifting block 43, and the guide rod is vertically set on the inner walls of both sides of the processing box 20, with the guide rod slidingly engaged with the guide groove. When the hydraulic cylinder 41 drives the lifting block 43 to move up and down, the engagement of the guide rod and the guide groove restricts the movement trajectory of the lifting block 43, preventing the lifting block 43 from tilting or rotating during the lifting process, thereby ensuring the parallelism of the upper conical roller 50 and the lower conical roller 60, improving the accuracy of the tapering process and the stability of the equipment operation.

[0056] Please see Figure 1 As shown, in some examples, there are two lower conical rollers 60, which are symmetrically arranged on the lower outer side of the processing box 20. The upper conical roller 50 is arranged above the two lower conical rollers 60 and between them. The three rollers cooperate to form a three-roller conical forming area.

[0057] This example further specifies the structure of the three-roller layout and the conical forming area. In the specific implementation of the scheme, two lower conical rollers 60 are symmetrically arranged on the lower outer side of the processing box 20, and the two ends of the roller shaft are fixed to the base 10 through bearing seats. The upper conical roller 50 is arranged above the two lower conical rollers 60 and between the two lower conical rollers 60, forming an inverted triangular layout. The roller surfaces of the three rollers can be set as smooth surfaces, patterned surfaces, conical surfaces, or forming surfaces with specific contours, depending on the processing requirements. For the conical processing of radar dome workpieces, the roller surface is usually set as conical or with a contour with progressive curvature. The sheet metal 80 is fed from the feed side between the upper conical roller 50 and the two lower conical rollers 60, and the conical forming is completed under the joint action of the three rollers. Through the three-roller layout, the sheet metal 80 is uniformly stressed and smoothly conveyed, thereby avoiding the sheet metal 80 from skewing, wrinkling, or stretching deformation during processing, improving the conical forming accuracy and product quality.

[0058] In a second aspect, based on the first aspect, this embodiment further describes in detail the processing method of the radar dome workpiece roll forming mechanism.

[0059] Please see Figures 1 to 10 As shown, a processing method for a radar radome workpiece rolling forming mechanism, applied to the radar radome workpiece rolling forming mechanism provided in the first aspect, includes the following steps:

[0060] S1. Feed the sheet material 80 to be processed into the three-roll conical forming area formed by the upper conical roller 50 and the two lower conical rollers 60; according to the thickness of the sheet material 80, start the hydraulic lifting mechanism 40, and drive the lifting block 43 to move up and down along the guide groove through the hydraulic cylinder 41, thereby moving the upper conical roller 50 to adjust to a suitable roller spacing.

[0061] S2. In step S1, while the lifting block 43 is displaced, the lifting block 43 drives the lifting beam 361 of the release amount adjustment component 36 to move up and down synchronously. The displacement of the lifting beam 361 is converted into the sliding of the transverse rod 362 along the direction perpendicular to the powder output pipe 35 through the inclined connecting rod 364, which mechanically changes the overlapping cross-sectional area of ​​the adjustment hole 363 and the powder output pipe 35: when the plate is thicker and the upper cone roller 50 is raised higher, the overlapping cross-sectional area is larger, and vice versa, thus completing the adaptive pre-adjustment of the friction powder output cross-section.

[0062] S3. Start the drive motor 21, and its power input is distributed to the multi-output transmission box 221: three of the power sources are transmitted to the lower cone roller 60 and the upper cone roller 50 respectively through the first cross universal transmission component 222 and the displacement transmission component 24, driving the cone rollers to rotate and roll the sheet 80; at the same time, the fourth power source of the multi-output transmission box 221 synchronously drives the air pump head 231 of the air pressure generating mechanism 23 to operate, drawing in outside air and outputting it to the surface of the sheet through the powder output pipe 35.

[0063] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
