Description

Technical Field

[0001] This invention relates to the field of radio frequency feeder cable manufacturing technology, and in particular to an apparatus for processing corrugated outer conductors of radio frequency feeders. Background Technology

[0002] In the manufacturing process of RF feeder cables, the corrugated outer conductor is a critical component, and its forming quality directly affects the cable's electrical performance (such as VSWR, attenuation, and characteristic impedance) and mechanical properties. Currently, this field faces the following long-standing and significant challenges: First, the short lifespan of traditional molds severely restricts production efficiency and costs. Existing molds are generally made of high-hardness mold steel, but during continuous copper strip rolling, the mold's working surface is subjected to intense friction and cyclic stress, leading to rapid wear. Specifically, critical molds have a lifespan of only 3 to 7 days. Frequent mold replacements not only result in high direct mold procurement costs but also lead to frequent production line adjustments, causing significant capacity losses and labor maintenance costs.

[0003] Secondly, frequent mold changes and adjustments lead to significant additional costs and quality fluctuations. Each mold change requires tedious process adjustments to meet product standards again. This adjustment process consumes large quantities of expensive copper strips as adjustment materials, resulting in high costs. Furthermore, manual adjustment is time-consuming and labor-intensive, and it's difficult to guarantee consistent results each time. Moreover, during the adjustment process, issues such as weak welding, weld penetration, water ingress, or saponification liquid damage frequently occur, directly affecting the product's electrical performance and significantly reducing the overall product pass rate and operational efficiency.

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The following is a reference appendix. Figure 1-8 An apparatus 100 for processing corrugated outer conductors for radio frequency feed lines according to an embodiment of the present invention is described.

[0025] First, the processing apparatus 100 for the corrugated outer conductor of the radio frequency feeder includes: a welding mold 10, a winding mold 20, a horn mold 30, and a sizing mold 40. When processing the radio frequency feeder cable, the copper strip 200 is first wound by the winding device to form a cylindrical structure. Then, the copper strip 200 is processed into the radio frequency feeder cable by passing through the horn mold 30, the welding mold 10, and the sizing mold 40 in sequence.

[0026] Reference Figure 1 , Figure 2 and Figure 3According to a first aspect embodiment of the present invention, a processing apparatus 100 for processing corrugated outer conductors of radio frequency feed lines has a processing groove extending through both sides of the processing apparatus 100 along a first direction, the first direction being the direction of cable movement, and the wall of the processing groove is provided with a nano-coating 50.

[0027] The present invention provides an apparatus 100 for processing corrugated outer conductors of radio frequency (RF) feed lines. A nano-coating 50 is provided in the processing tank. When the RF feed line cable moves from front to back in the processing tank, the surface of the RF feed line cable will rub against the surface of the processing tank. Due to the effect of the nano-coating 50, the nano-coating 50 can reduce the friction between the RF feed line cable and the processing tank, thereby reducing damage to the wall of the processing tank, thus increasing the service life of the processing apparatus 100 and reducing maintenance costs. At the same time, the reduced wear on the wall of the processing tank can ensure the accuracy of the processing apparatus 100, thereby ensuring the processing quality of the RF feed line.

[0028] Furthermore, the processing device 100 can maintain relatively stable accuracy for a long time without the need for frequent replacements, thus effectively ensuring the production efficiency of the processing device 100. At the same time, it can also reduce the pre-production debugging costs and labor costs caused by replacing the processing device 100, thereby reducing processing costs. In addition, if the processing accuracy of the same batch of RF feeder cables is improved, the connection strength, waterproof and anti-interference performance of the entire RF feeder cable can be guaranteed, thereby effectively improving the electrical performance of the RF feeder cable.

[0029] According to an embodiment of the present invention, a processing apparatus 100 for corrugated outer conductor of radio frequency feeder is provided with a nano-coating 50 on the inner wall of the processing tank. The nano-coating 50 can reduce the friction between the radio frequency feeder cable and the nano-coating 50, thereby reducing damage to the wall of the processing tank. At the same time, it can improve the wear resistance of the processing apparatus 100, thereby increasing the service life of the processing apparatus 100, reducing maintenance costs, and ensuring the processing quality of the radio frequency feeder cable.

[0030] According to some embodiments of the present invention, with reference to Figure 1 , Figure 2 and Figure 3 An apparatus 100 for processing corrugated outer conductors of radio frequency feed lines includes: a welding mold 10, wherein a processing groove is formed in the welding mold 10 as a welding groove 11, and the welding groove 11 is along a first direction (e.g., Figure 2 The welding groove 11 has a nano-coating 50 on the walls of the welding mold 10, which extends through both sides of the welding mold 10 in the front-back direction shown.

[0031] In this way, a nano-coating 50 is provided inside the welding groove 11. When the RF feed cable moves from front to back inside the welding groove 11, the surface of the RF feed cable will rub against the surface of the welding groove 11. Due to the effect of the nano-coating 50, the nano-coating 50 can reduce the friction between the RF feed cable and the nano-coating 50, thereby reducing the damage to the wall of the welding groove 11, which can improve the service life of the welding mold 10 and reduce maintenance costs. At the same time, the reduced wear on the wall of the welding groove 11 can ensure the accuracy of the welding mold 10, thereby ensuring the processing quality of the RF feed cable.

[0032] For example, such as Figure 1 , Figure 2 and Figure 3 As shown, the welding mold 10 extends through the front and rear surfaces of the welding mold 10 in the front-back direction, and adjacent cables are welded at the outlet of the welding tank 11. The wall of the welding tank 11 is provided with a nano-coating 50.

[0033] According to some embodiments of the present invention, with reference to Figure 1 and Figure 2 The welding groove 11 has an inlet 111 and an outlet 112 at its two ends, and the welding mold 10 has chamfers at both the inlet 111 and the outlet 112. Therefore, when the RF feeder cable enters the welding groove 11 from the inlet 111 and flows out of the welding groove 11 from the outlet 112, scratches on the RF feeder cable can be prevented, thereby improving the processing quality of the RF feeder cable.

[0034] For example, such as Figure 1 and Figure 2 As shown, the front end of the welding groove 11 forms an inlet 111, and the rear end of the welding groove 11 forms an outlet 112. The inlet 111 and the outlet 112 are both chamfered.

[0035] According to some embodiments of the present invention, with reference to Figure 1 and Figure 2 The chamfer radius of the inlet 111 is between 0.8mm and 1.2mm. Therefore, the chamfer radius of the inlet 111 is reasonably set, which can facilitate processing and ensure that the inlet 111 does not damage the cable.

[0036] For example, such as Figure 1 and Figure 2 As shown, the chamfer radius of the inlet 111 can be 0.8mm, 0.9mm, 1mm, 1.1mm, and 1.2mm.

[0037] Furthermore, the chamfer radius of the outlet 112 is between 1.3mm and 1.7mm. Therefore, the chamfer radius of the outlet 112 is reasonably set, which facilitates processing while ensuring that the outlet 112 does not damage the cable.

[0038] For example, such as Figure 1 and Figure 2 As shown, the chamfer radius of the outlet 112 can be 1.3mm, 1.4mm, 1.5mm, 1.6mm, and 1.7mm.

[0039] According to some embodiments of the present invention, with reference to Figure 1 and Figure 2 The welding mold 10 has an inlet 111 at one end (e.g., Figure 1 The front end of the welding mold 10 shown has a clearance portion 12, which is formed along a first direction (e.g., Figure 1 (As shown in the front-back direction) extends away from the inlet 111, and the interior of the clearance part 12 defines a clearance groove 121. The clearance groove 121 is connected to the inlet 111, and the diameter of the clearance groove 121 is larger than the diameter of the inlet 111.

[0040] In this way, the clearance section 12 defines the clearance groove 121, eliminating the need for additional processing of the clearance groove 121 and reducing processing steps. At the same time, the clearance groove 121 effectively prevents the RF feeder cable from rubbing against the area around the inlet 111 when the cable flows out of the outlet 112 of the welding groove 11, thereby effectively protecting the RF feeder cable. In addition, the diameter of the clearance groove 121 is reasonably set, which can effectively prevent the RF feeder cable from rubbing against the welding mold 10 and causing damage.

[0041] For example, such as Figure 1 and Figure 2 As shown, the front end of the welding mold 10 forms a clearance portion 12, which extends forward in the front-back direction and extends in a ring shape along the circumference of the inlet 111. The clearance portion 12 defines a clearance groove 121 inside the clearance portion 12. The rear end of the clearance groove 121 is connected to the inlet 111 of the welding groove 11. The diameter of the clearance groove 121 is larger than the diameter of the inlet 111.

[0042] According to some optional embodiments of the present invention, refer to Figure 1 and Figure 2 The number of clearance parts 12 is two, and the two clearance parts 12 are arranged at the inlet 111 in the second direction (e.g., Figure 2 On both sides (as shown in the left and right directions), a clearance groove 121 is defined between the two clearance portions 12, and the second direction and the first direction (as shown in the left and right directions) Figure 2 (as shown in the front-to-back direction) is perpendicular. Therefore, the two clearance parts 12 have a simple structure and are easy to set up, which facilitates the fabrication of the welding mold 10.

[0043] According to some optional embodiments of the present invention, refer to Figure 1 and Figure 2 The end of the clearance section 12 is away from the inlet 111 (e.g.) Figure 2The front end of the clearance portion 12 shown is chamfered. This prevents the end of the clearance portion 12 from scratching the surface of the RF feeder cable, thereby effectively protecting the RF feeder cable and improving the quality of RF feeder cable processing.

[0044] According to some embodiments of the present invention, with reference to Figure 1 , Figure 3 and Figure 4 The apparatus 100 for processing corrugated outer conductors of radio frequency feed lines includes: a winding die 20, which is located upstream of the welding die 10 and is used to wind up the cable; a processing groove is formed on the winding die 20 as an upwardly opening U-shaped groove 21, the U-shaped groove 21 being along a first direction (e.g., Figure 3 The U-shaped groove 21 (shown in the front-to-back direction) penetrates the winding die 20, with the two ends being a first end 211 and a second end 212, respectively. The second end 212 is located downstream of the first end 211. The cross-sectional area of ​​the first end 211 is larger than that of the second end 212. The first end 211 is located in the second direction (as shown in the front-to-back direction). Figure 3 The two sides of the second end 212 (shown in the left and right directions) are chamfered, and the two sides of the second end 212 are chamfered in the second direction.

[0045] In this way, the copper strip 200 passes through the U-shaped groove 21, which can wind the long strip of copper strip 200 into a hollow cylinder. This makes it easy for the copper strip 200 to be combined with the inner conductor to form an RF feeder cable. At the same time, the cross-sectional area of ​​the first end 211 and the second end 212 is set in a reasonable way, which can effectively wind the copper strip 200 into a hollow cylinder. In addition, the chamfer can prevent the copper strip 200 from being scratched in the U-shaped groove 21, thereby effectively improving the processing quality of the RF feeder cable.

[0046] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the winding mold 20 is located upstream of the welding mold 10. The U-shaped groove 21 penetrates the winding mold 20 in the front-back direction and penetrates the upper surface of the winding mold 20. The front end of the U-shaped groove 21 is the first end 211, and the rear end of the U-shaped groove 21 is the second end 212.

[0047] According to some embodiments of the present invention, with reference to Figure 1 , Figure 3 and Figure 4 The diameter of the chamfer at the first end 211 is 1.8mm-2.2mm. Therefore, the diameter of the chamfer at the first end 211 is reasonably set, which facilitates the chamfering process. At the same time, limiting the diameter of the chamfer at the first end 211 can prevent damage to the surface of the RF feeder cable during the processing, thereby improving the processing quality.

[0048] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the diameters of the chamfers at the first end 211 are 1.8mm, 1.9mm, 2mm, 2.1mm and 2.2mm.

[0049] According to some embodiments of the present invention, with reference to Figure 1 , Figure 3 and Figure 4 The diameter of the chamfer at the second end 212 is 0.8mm-1.2mm. Therefore, the chamfer diameter at the second end 212 is reasonably set, which facilitates the chamfering process and prevents damage to the surface of the RF feeder cable during processing, thereby improving processing quality.

[0050] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the diameters of the chamfers at the second end 212 are 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, and 1.2 mm.

[0051] According to some embodiments of the present invention, with reference to Figure 1 , Figure 3 and Figure 4 The first end 211 is in the second direction (e.g.) Figure 3 The length (shown in the left-right direction) is 16mm-118mm. Therefore, the width of the first end 211 can be adjusted according to actual needs, ensuring that the winding die 20 can process cables of various sizes.

[0052] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the length of the first end 211 in the left-right direction can be 16mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm and 118mm.

[0053] According to some embodiments of the present invention, with reference to Figure 1 , Figure 3 and Figure 4 U-shaped groove 21 in the second direction (e.g. Figure 3 The copper strip 200 has a first edge 213 and a second edge 214 on both sides (as shown in the left-right direction). The first edge 213 and the second edge 214 extend in a straight line towards each other in the direction from the first end 211 to the second end 212. Thus, the first edge 213 and the second edge 214 can guide the winding direction of the copper strip 200, thereby ensuring that the copper strip 200 can be wound into the required structural shape, and thus ensuring the processing quality of the copper strip 200.

[0054] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the left edge of the U-shaped groove 21 is the second edge 214, and the right edge of the U-shaped groove 21 is the first edge 213. In the direction from front to back, the first edge 213 and the second edge 214 extend in opposite directions.

[0055] According to some embodiments of the present invention, with reference to Figure 1 , Figure 3 and Figure 4 The first edge 213 and the second edge 214 in the first direction (e.g.) Figure 3 The copper strip 200 is arranged symmetrically in the front-to-back direction (as shown). This ensures that the copper strip 200 can be wound evenly, and that the edges of the copper strip 200 can be tightly connected in the left-to-right direction, thereby further improving the quality of cable processing.

[0056] According to some embodiments of the present invention, with reference to Figure 1 , Figure 3 and Figure 4 The angle between the first edge 213 and the second edge 214 is within the range of 18°-19°. Therefore, the angle between the first edge 213 and the second edge 214 is set reasonably, which can ensure that the copper strip 200 can be wound normally.

[0057] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the angle between the first edge 213 and the second edge 214 is within the range of 18°, 18.1°, 18.2°, 18.3°, 18.4°, 18.5°, 18.6°, 18.7°, 18.8°, 18.9° and 19°.

[0058] According to some embodiments of the present invention, with reference to Figure 1 , Figure 3 and Figure 4 The first edge 213 includes a first segment 2131 and a second segment 2132 connected together, one end of the first segment 2131 (e.g. Figure 3 The left end of the first segment 2131 shown is connected to the bottom wall of the U-shaped groove 21, and the other end of the first segment 2131 (as shown) is connected to the bottom wall of the U-shaped groove 21. Figure 3 The right end of the first segment 2131 shown extends upward away from the U-shaped groove 21 and curves away from the second edge 214. One end of the second segment 2132 (as shown) Figure 3 The lower end of the second segment 2132 shown) and the other end of the first segment 2131 (as shown) Figure 3 The right end of the first segment 2131 shown is connected, and the other end of the second segment 2132 (as shown) is connected. Figure 3 The upper end of the second segment 2132 shown extends vertically in the up-down direction.

[0059] In this way, the first segment 2131 extends along the curve, which can prevent the copper strip 200 from being scratched at the corners of the first edge 213 in the U-shaped groove 21. At the same time, the second segment 2132 extends in a reasonable direction, which can prevent the copper strip 200 from coming out of the U-shaped groove 21, thereby ensuring the efficiency of copper strip 200 processing.

[0060] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the left end of the first segment 2131 is connected to the bottom wall of the U-shaped groove 21, the right end of the first segment 2131 extends to the right and upward in a curved manner, the lower end of the second segment 2132 is connected to the right end of the first segment 2131, and the upper end of the second segment 2132 extends vertically upward in the up-down direction.

[0061] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, the second edge 214 includes a connected third segment 2141 and a fourth segment 2142, one end of the third segment 2141 (as shown) Figure 3 The right end of the third segment 2141 shown is connected to the bottom wall of the U-shaped groove 21, and the other end of the third segment 2141 (as shown) Figure 3 The left end of the third segment 2141 shown extends upward away from the U-shaped groove 21 and curves away from the first edge 213. One end of the fourth segment 2142 (as shown) Figure 3 The lower end of the fourth segment 2142 (as shown) is connected to the other end of the third segment 2141, and the other end of the fourth segment 2142 (as shown) Figure 3 The upper end of the fourth segment 2142 shown extends vertically in the up-down direction.

[0062] In this way, the third segment 2141 extends along the curve, which can prevent the copper strip 200 from being scratched at the corners of the second edge 214 in the U-shaped groove 21. At the same time, the fourth segment 2142 extends in a reasonable direction, which can prevent the copper strip 200 from coming out of the U-shaped groove 21, thereby ensuring the efficiency of the copper strip 200 processing.

[0063] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the right end of the third segment 2141 is connected to the bottom wall of the U-shaped groove 21, the left end of the first segment 2131 extends to the left and upward in a curved manner, the lower end of the fourth segment 2142 is connected to the left end of the first segment 2131, and the upper end of the fourth segment 2142 extends vertically upward in the up-down direction.

[0064] According to some optional embodiments of the present invention, refer to Figure 1 , Figure 3 and Figure 4The surfaces of the first edge 213 and the second edge 214 facing each other are provided with a nano-coating 50. As a result, the nano-coating 50 can reduce the friction between the RF feed cable and the nano-coating 50, thereby reducing damage to the wall of the welding groove 11, which in turn can improve the service life of the welding mold 10, reduce maintenance costs, and ensure the processing quality of the RF feed cable U-shaped groove.

[0065] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the surfaces of the first edge 213 and the second edge 214 facing each other are provided with a nano-coating 50. When the cable passes through the U-shaped groove 21, the RF feed cable rubs against the wall of the nano-coating 50 in the U-shaped groove 21, thereby reducing the friction between the cable and the inner wall of the U-shaped groove 21.

[0066] According to some optional embodiments of the present invention, refer to Figure 1 , Figure 3 and Figure 4 The winding die 20 is a cuboid, and all its edges are chamfered. This prevents workers from being scratched by the sharp edges of the winding die 20 during manual operation.

[0067] According to some embodiments of the present invention, with reference to Figure 1 and Figure 7 The apparatus 100 for processing corrugated outer conductors of radio frequency feed lines includes: a horn mold 30, which is disposed upstream of the welding mold 10; a processing groove is formed on the horn mold 30 as a horn groove 31; the horn groove 31 is along a first direction (e.g., Figure 7 The front and rear directions shown) penetrate the horn mold 30, and the horn groove 31 has a nano-coating 50 on the surface of both ends in the first direction.

[0068] In this way, the speaker mold 30 can further wind the cable into a cylindrical structure, thereby improving the processing quality of the cable. At the same time, the RF feeder cable can come into contact with the nano-coating 50 in the speaker groove 31, thereby protecting the speaker groove 31 and the speaker mold 30, effectively extending the service life of the speaker mold 30.

[0069] For example, such as Figure 1 and Figure 7 As shown, the horn mold 30 is located on the upstream side of the welding mold 10. The horn groove 31 extends through the horn groove 31 in the front-to-back direction. The horn groove 31 has an inlet end and an outlet end. Both the inlet end and the outlet end of the horn groove 31 are provided with a nano-coating. The diameter of the inlet end of the horn groove 31 is larger than the diameter of the outlet end. The nano-coating 50 is thicker, which can prevent the cable from contacting the wall of the horn groove 31 inside the horn groove 31, thereby protecting the surface of the RF feeder cable.

[0070] Preferably, the nano-coating 50 inside the horn mold 30 can be rotated, which can prevent the nano-coating 50 from being damaged by scratches caused by long-term use during long-term use.

[0071] According to some embodiments of the present invention, with reference to Figure 1 and Figure 8 The apparatus 100 for processing corrugated outer conductors of radio frequency feed lines further includes: a sizing die 40, which is disposed downstream of the welding die 10, and a processing groove is formed on the sizing die 40 as a sizing groove 41, the sizing groove 41 being along a first direction (e.g., Figure 8 The sizing mold 40 (shown in the front-back direction) passes through the sizing groove 41, and the surface of the sizing groove 41 is provided with a nano-coating 50. The sizing mold 40 is used to promote the longitudinal wrapping of copper strip.

[0072] In this way, the sizing groove 41 can not only correct the diameter of the cable and improve the quality of the cable, but also allow the RF feeder cable to come into contact with the nano-coating 50 inside the sizing groove 41, thereby protecting the sizing groove 41 and the sizing mold 41, effectively extending the service life of the sizing mold 41.

[0073] For example, such as Figure 1 and Figure 8 As shown, the sizing mold 40 is located on the downstream side of the welding mold 10, and the sizing groove 41 extends through the sizing mold 40 in the front-to-back direction. The surface of the sizing groove 41 is provided with a nano-coating 50.

[0074] According to some embodiments of the present invention, with reference to Figure 1 and Figure 8 The diameter of the sizing groove 41 is in the range of 6.7mm-47mm. Therefore, the diameter of the sizing groove 41 can be adjusted according to actual needs, thereby ensuring that the radio frequency feeder corrugated outer conductor processing device 100 can process cables of various specifications.

[0075] For example, such as Figure 1 and Figure 8 As shown, the diameter of the sizing groove 41 can be 6.7mm, 10mm, 20mm, 30mm, 40mm and 47mm.

[0076] The following is for reference. Figures 1-8 An apparatus 100 for processing corrugated outer conductors for radio frequency feed lines according to an embodiment of the present invention is described.

[0077] According to an embodiment of the present invention, an apparatus 100 for processing corrugated outer conductors of radio frequency feed lines, such as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the processing apparatus 100 for corrugated outer conductors of radio frequency feed lines includes: a welding die 10, a winding die 20, a horn die 30, and a sizing die 40. The welding die 10 has a welding groove 11, the winding die 20 has a U-shaped groove 21, the horn die 30 has a horn groove 31, and the sizing die 40 has a sizing groove 41. The winding die 20, the horn die 30, the welding die 10, and the sizing die 40 are arranged sequentially from front to back.

[0078] When processing RF feeder cables using the RF feeder corrugated outer conductor processing apparatus 100, the copper strip 200 is wound through the U-shaped groove of the winding die 20. The copper strip 200 contacts the nano-coating 50 in the U-shaped groove 21. Then, the copper strip 200 further forms a hollow cylindrical structure in the horn groove 31, and the copper strip 200 contacts the nano-coating 50 in the horn groove 31. Then, the copper strip 200 is welded in the welding groove 11, and the copper strip 200 contacts the nano-coating 50 in the welding groove 11. Finally, the copper strip 200 enters the sizing groove 41 from the welding groove 11, and the copper strip 200 contacts the nano-coating 50 in the sizing groove 41. Thus, the processing of the RF feeder cable is completed.

[0079] The RF feeder corrugated outer conductor processing apparatus 100 of this embodiment has a nano-coating 50 on the inner wall of the processing tank. The nano-coating 50 can reduce the friction between the RF feeder cable and the nano-coating 50, thereby reducing damage to the wall of the processing tank. At the same time, it can improve the wear resistance of the processing apparatus 100, thereby increasing the service life of the processing apparatus 100, reducing maintenance costs, and ensuring the processing quality of the RF feeder cable.
