Description

Technical Field

[0001] This invention relates to the field of cable corrugation technology, specifically to a segmented corrugation device for radio frequency coaxial cables. Background Technology

[0002] In existing feeder production processes, the spiral corrugation method for the outer conductor of mobile communication radio frequency coaxial cables is generally divided into two types: eccentric corrugation and concentric corrugation. Concentric spiral corrugation involves installing a corrugating plate on the corrugating head, with the axis of the corrugating plate bending and coinciding with the axis of the welded pipe being processed. During the corrugating process, the working area of ​​the corrugating plate simultaneously acts on the welded pipe. The concentric corrugating device has the following drawbacks: 1. The corrugating die is a single piece, the working area diameter of the corrugating plate cannot be changed, and the corrugating depth is not adjustable. Therefore, process adjustments cannot be made based on the actual characteristic impedance of the cable during outer conductor corrugation production; 2. Due to the high friction between the corrugating plate and the welded pipe being processed, the arc of the corrugating plate's working area wears quickly, resulting in a short service life for the corrugating die, with a single corrugating plate yielding only about 10 km; 3. The rapid wear of the working area arc of the corrugating die necessitates frequent replacement to ensure that the actual characteristic impedance of the cable meets product requirements, increasing the consumption of raw materials during continuous production. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a segmented corrugating device for radio frequency coaxial cables. The corrugating depth can be adjusted according to processing requirements, and the distance between the corrugated sheets can be adjusted to solve the impact of side wear in the friction working area, thereby adjusting the corrugating pitch and improving the corrugating effect.

[0004] The objective of this invention is achieved through the following technical solution: a segmented corrugating device for radio frequency coaxial cables, comprising a corrugating machine and a corrugating die.

The inlet rolling sheet, correction rolling sheet, and forming rolling sheet are respectively mounted on three adjustment seats. The inlet rolling sheet, correction rolling sheet, and forming rolling sheet are arranged alternately along the axial direction of the annular mounting seat. The correction rolling sheet and the forming rolling sheet have the freedom to move along the axial direction of the annular mounting seat.

[0010] In some embodiments, both the adjusting seat for the correcting rolled sheet and the adjusting seat for the forming rolled sheet are provided with shaft locking mechanisms. The shaft locking mechanism includes a fixed locking block and a movable locking block. The end face of the adjusting seat away from the annular mounting seat has a circular hole and a rectangular cavity sequentially formed along the direction close to the annular mounting seat. Bearings are fitted on the first lead screw and the second lead screw, and the bearings are installed in the circular hole. Fixed locking blocks and movable locking blocks are arranged at radial intervals along the annular mounting seat in the rectangular cavity. The first lead screw and the second lead screw both extend between the fixed locking block and the movable locking block. The opposite end faces of the fixed locking block and the movable locking block are provided with arc-shaped locking grooves. The diameters of the first lead screw and the second lead screw are both smaller than the diameter of the arc-shaped locking grooves. The movable locking block is slidably disposed in the rectangular cavity. A screw is rotatably connected to the end of the movable locking block away from the fixed locking block, and the screw is threaded through the adjusting seat.

[0011] In some embodiments, a bidirectional threaded screw is rotatably disposed within the annular cavity. The bidirectional threaded screw is radially parallel to the annular mounting base. Clamping and limiting plates are threaded onto the two threaded sections of the bidirectional threaded screw with opposite directions. A limiting ring is coaxially fixed to the bottom of the internal gear ring. The two clamping and limiting plates are located on the outer and inner sides of the limiting ring, respectively. Friction plates are fixed to the opposite end faces of the two clamping and limiting plates.

[0012] In some embodiments, a drive seat is fixed on the embossing machine platform, and a central hole is opened through the middle of the drive seat.

[0014] The beneficial effects of this invention are:

[0015] 1. The corrugated forming assembly is segmented and staggered along the cable conveying direction, so that each segment of the corrugated forming assembly has radial movement space along the annular mounting base. When the straightening spiral teeth and forming spiral teeth are worn, the diameter of the corrugated working area can be changed by adjusting the movement of the adjusting base, so that the corrugation depth can be adjusted according to actual needs, increasing the service life of the corrugated forming assembly and reducing mold costs.

[0016] 2. Considering that the friction between the straightening spiral teeth and the forming spiral teeth occurs not only at their ends but also on their sides, resulting in varying degrees of wear on the sides of both teeth, and that both the straightening and forming plates can move axially along the annular mounting base, the distance between the straightening plate and the inlet plate, and between the straightening plate and the forming plate can be adjusted. This solves the problem of side wear in the friction working area, ensuring that the pitch of the rolled pattern is not affected. The corresponding pitch can be adjusted according to the rolling pattern requirements, resulting in a better rolling pattern effect.

[0017] 3. The spiral teeth are heated by an electric heating wire, which in turn heats the cable sheath. The heated sheath is more likely to deform, thereby reducing the friction between the spiral teeth and the sheath, which in turn reduces the wear of the spiral teeth and extends the service life of the corrugated assembly.

Detailed Implementation

[0028] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0029] like Figures 1 to 9As shown, a segmented corrugating device for radio frequency coaxial cables includes a corrugating machine 1 and a corrugating die 2. The corrugating die 2 includes an annular mounting base 3 and a corrugating forming assembly. The annular mounting base 3 is rotatably mounted on the corrugating machine 1 with its axis horizontal. Three adjusting seats 7 are slidably disposed on the end face of the annular mounting base 3. The three adjusting seats 7 are evenly distributed along the circumference of the annular mounting base 3 and have the freedom to move radially along the annular mounting base 3. The corrugating forming assembly is a split disc and includes an inlet strip 4, a correction strip 5, and a forming element, which are equally divided along their own circumference. The inner walls of the rolling mill 6, the inlet rolling mill 4, the straightening rolling mill 5, and the forming rolling mill 6 are respectively provided with introducing spiral teeth 8, straightening spiral teeth 9, and forming spiral teeth 10. The inlet rolling mill 4, the straightening rolling mill 5, and the forming rolling mill 6 are respectively set on three adjusting seats 7. The inlet rolling mill 4, the straightening rolling mill 5, and the forming rolling mill 6 are arranged alternately along the axial direction of the annular mounting seat 3. The straightening rolling mill 5 and the forming rolling mill 6 both have the freedom to move along the axial direction of the annular mounting seat 3. The introducing spiral teeth 8, the straightening spiral teeth 9, and the forming spiral teeth 10 are all made of high-strength alloy steel and have high anti-friction performance. The corrugating assembly is configured as a segmented structure, consisting of an inlet plate 4, a straightening plate 5, and a forming plate 6. These three plates form an annular structure for corrugating the cable. Within this annular structure, an introductory spiral tooth 8, a straightening spiral tooth 9, and a forming spiral tooth 10 create a spiral corrugated structure. The inlet plate 4, straightening plate 5, and forming plate 6 are respectively mounted on three movable adjusting seats 7. These adjusting seats 7 can move radially along the annular mounting base 3, thereby adjusting the diameter of the annular structure. Furthermore, when the corrugating assembly is worn or different corrugation depths are required, the corrugation depth can be changed by adjusting the diameter of the annular structure. During the process, the forming spiral teeth 10 are embedded in the cable sheath to create patterns. Therefore, in addition to the wear caused by the ends of the forming spiral teeth 10 and the straightening spiral teeth 9 contacting the cable sheath, the sides of the straightening spiral teeth 9 and the sides of the forming spiral teeth 10 also contact the cable sheath and experience wear. The wear on both sides affects the pattern pitch and the patterning effect. However, both the straightening plate 5 and the forming plate 6 can move axially along the annular mounting base 3, which can adjust the distance between the straightening plate 5 and the inlet plate 4, and the distance between the straightening plate 5 and the forming plate 6. This solves the problem of wear on the sides of the friction working area, ensuring that the patterning pitch is not affected and improving the patterning effect.

[0030] Furthermore, such as Figure 1As shown, a drive seat 49 is fixed on the corrugating machine base 1. A central hole is opened through the middle of the drive seat 49. An annular mounting seat 3 is rotatably installed in the central hole through a drive bearing. An external gear ring 41 is fitted on the outer wall of the annular mounting seat 3. A geared motor 42 is installed on the drive seat 49. A pinion 43 is installed on the output shaft of the geared motor 42. The pinion 43 meshes with the external gear ring 41. Cable reels are set at both ends of the corrugating machine base 1. One cable reel rotates to release the cable. The cable passes through the central hole and is wound around the corrugating forming component on the other cable reel. At the same time, the geared motor 42 drives the annular mounting seat 3 to rotate through the meshing of the pinion 43 and the external gear ring 41, thereby driving the corrugating forming component to rotate. Through the rotational degree of freedom of the corrugating forming component, combined with the linear traction degree of freedom of the cable, the corrugating forming component performs corrugation treatment on the cable sheath to form a spiral pattern.

[0031] In some embodiments, such as Figures 1 to 6 As shown, a threaded post 11 is fixed to the inner wall of the inlet lamination 4. A heating post 12 is coaxially fixed to the end of the threaded post 11 away from the inlet lamination 4. An electric heating wire is built into the heating post 12. The diameter of the threaded post 11 is larger than the diameter of the heating post 12. An internal threaded hole 13 and a heating hole 14 are sequentially opened on the outer wall of the guide spiral tooth 8 along its own center direction. The heating post 12 is adapted to the heating hole 14, and the threaded post 11 is threaded into the internal threaded hole 13. The guide spiral tooth 8 is heated by the electric heating wire, and the guide spiral tooth 8 heats the cable sheath. The heated sheath is more likely to deform, thereby reducing the cost. The friction between the helical teeth 10 and the sheath reduces the wear of the forming helical teeth 10, thereby extending the service life of the texturing forming assembly. Through the adaptation of the threaded post 11 and the internal threaded hole 13, the inlet helical teeth 8 can be detachably installed on the inlet strip 4. Similarly, the straightening helical teeth 9 and the forming helical teeth 10 are installed by threaded connection. When the straightening helical teeth 9 and the forming helical teeth 10 are severely worn and texturing cannot be performed by adjusting the diameter of the annular structure, the straightening helical teeth 9 and the forming helical teeth 10 are replaced, thereby partially replacing the texturing forming assembly and reducing replacement costs.

[0032] In some embodiments, such as Figures 1 to 4As shown, an annular mounting base 3 has an annular cavity 15 coaxially arranged inside. An internal gear ring 16 is rotatably arranged inside the annular cavity 15. Three adjusting shafts 17 are evenly distributed around the circumference of the annular cavity 15. The adjusting shafts 17 are rotatably connected to the annular mounting base 3. Gears 18 and precision gears 19 are mounted on the adjusting shafts 17. Gear 18 meshes with the internal gear ring 16, and precision gear 19 meshes with a spur rack 20. The spur rack 20 slides through the annular mounting base 3. The annular mounting base 3 has a radial groove 21 corresponding to the position of the adjusting seat 7. The radial groove 21 connects to the annular cavity 15. The spur rack 20 is fixedly connected to a connecting plate 22. The connecting plate 22 passes through the radial groove 21 and connects to the adjusting seat 7. One of the adjusting shafts 17 An internal threaded nut 52 is fixed to the annular mounting base 3. Using a wrench to turn the internal threaded nut 52, the corresponding adjusting shaft 17 is rotated. The adjusting shaft 17 drives the gear 18 and precision gear 19 on it to rotate. The gear 18 drives the internal gear ring 16 to rotate. The internal gear ring 16 drives the remaining gears 18 to rotate, so that the three adjusting shafts 17 rotate synchronously. The adjusting shaft 17 drives the precision gear 19 to rotate. The precision gear 19 drives the rack 20 to move. The rack 20 drives the adjusting base 7 to move. By rotating the internal threaded nut 52 in both directions, the adjusting base 7 moves away from or closer to the center of the annular mounting base 3, thereby adjusting the diameter of the annular structure and changing the groove depth. Because the strength of the contact sleeve between the correcting helical teeth 9 and the forming helical teeth 10 is different, the degree of wear is also different. Therefore, the synchronous movement of the three adjusting seats 7 in the above structure cannot be adjusted according to the degree of wear. For this reason, the precision gear 19 is not connected to the adjusting shaft 17 by a key. An elastic friction sleeve is fixed to the inner wall of the precision gear 19. The inner diameter of the elastic friction sleeve is smaller than the diameter of the adjusting shaft 17. Deformation is generated by compressing the elastic friction sleeve, allowing it to be interference-fitted onto the adjusting shaft 17 through its own deformation. Two shoulders are fixed on the adjusting shaft 17, and the two ends of the precision gear 19 abut against the two shoulders respectively. Under normal circumstances... In this situation, the adjusting shaft 17 rotates, and the friction generated by the elastic friction sleeve drives the precision gear 19 to rotate. The movement of the adjusting seat 7 is restricted by the tooling fixture or other limiting device. At this time, as the torque increases, the adjusting shaft 17 will overcome the friction generated by the elastic friction sleeve and rotate relative to the precision gear 19. Under the condition that the movement of the adjusting seat 7 is restricted, the adjusting shaft 17 can rotate normally without interference. The adjusting seat 7, whose degree of freedom of movement is not restricted, can move normally, so that the inlet rolling sheet 4, the correction rolling sheet 5, and the forming rolling sheet can move different distances. It can be adjusted according to the degree of wear, so that the adjustment accuracy is higher.

[0033] In some embodiments, such as Figures 1 to 3As shown, a first lead screw 23 is rotatably connected to the adjusting seat 7 for setting the correction sheet 5. The correction sheet 5 is threaded onto the first lead screw 23. The end of the first lead screw 23 away from the adjusting seat 7 is rotatably connected to a first mounting plate 24. A first slide rod 25 slides through the correction sheet 5. The two ends of the first slide rod 25 are respectively fixedly connected to the adjusting seat 7 and the first mounting plate 24. A second lead screw 26 is rotatably connected to the adjusting seat 7 for setting the forming sheet 6. The forming sheet 6 is threaded onto the second lead screw 26. The end of the second lead screw 26 away from the adjusting seat 7 is rotatably connected to a second mounting plate 27. A second slide rod 28 slides through the forming sheet 6. The two ends of the second slide rod 28 are respectively fixedly connected to the second mounting plate 27 and the adjusting seat 7. The first lead screw 23 passes through the first mounting plate 24 and is fixed to a first turntable 29. The second lead screw 26 passes through the second mounting plate 27 and is fixed to a second turntable 30. Indicator arrows 31 are provided on the side walls of both the first turntable 29 and the second turntable 30. The first mounting plate 24 is surrounded by... The first lead screw 23 is equipped with a first angle scale, and the second mounting plate 27 is equipped with a second angle scale around the second lead screw 26. By rotating the first turntable 29, the first lead screw 23 is driven to rotate. Since the correction plate 5 is slidably sleeved on the first slide rod 25, the rotational freedom of the correction plate 5 is restricted, causing the correction plate 5 to move axially along the annular mounting base 3. When the correction spiral tooth 9 is worn, the first turntable 29 is rotated to move the correction plate 5 closer to the inlet plate 4, adjusting the pitch between the inlet spiral tooth 8 and the correction spiral tooth 9. Then, the second turntable 30 is rotated to drive the second lead screw 26 to rotate. The rotational freedom of the forming plate 6 is restricted by the sliding fit between the forming plate 6 and the second slide rod 28, causing the forming plate 6 to move axially along the annular mounting base 3. After the position of the correction plate 5 is adjusted, the forming plate 6 is moved closer to the correction plate 5, changing the pitch between the forming spiral tooth 10 and the correction spiral tooth 9, thereby compensating for the wear on the side of the corrugated forming assembly.

[0034] In some embodiments, such as Figures 1 to 8As shown, both the adjusting seat 7 for setting the correction sheet 5 and the adjusting seat 7 for setting the forming sheet 6 are equipped with shaft locking mechanisms. The shaft locking mechanisms include a fixed locking block 37 and a movable locking block 38. A circular hole 34 and a rectangular cavity 35 are sequentially opened on the end face of the adjusting seat 7 away from the annular mounting seat 3 along the direction close to the annular mounting seat 3. Bearings 36 are fitted onto both the first lead screw 23 and the second lead screw 26. The bearings 36 are installed in the circular hole 34. Fixed locking blocks 37 and movable locking blocks 38 are arranged radially at intervals within the rectangular cavity 35 along the annular mounting seat 3. Both the first lead screw 23 and the second lead screw 26 extend between the fixed locking block 37 and the movable locking block 38. Both the end faces of block 37 and the movable locking block 38 are provided with arc-shaped locking grooves 39. The diameters of the first lead screw 23 and the second lead screw 26 are smaller than the diameter of the arc-shaped locking grooves 39. The first lead screw 23 contacts the arc-shaped locking groove 39 of the corresponding fixed locking block 37, and similarly, the second lead screw 26 contacts the arc-shaped locking groove 39 of the corresponding fixed locking block 37. The movable locking block 38 is slidably disposed in the rectangular cavity 35. The end of the movable locking block 38 away from the fixed locking block 37 is rotatably connected to a screw 40, which is threaded onto the adjusting seat 7. Due to the large interaction strength between the corrugating forming component and the cable sheath during the corrugating process, in order to ensure that during the corrugating process... The straightening sheet 5 and the forming sheet 6 will not move abnormally. After the straightening sheet 5 and the forming sheet 6 are adjusted, the first lead screw 23 and the second lead screw 26 are locked respectively by the shaft locking mechanism. Taking the locking of the first lead screw 23 as an example, after the axial position of the straightening sheet 5 is adjusted, the screw 40 is rotated. The screw 40 moves on the adjusting seat 7 by screwing in. Through the rotational connection between the screw 40 and the moving locking block 38, the moving locking block 38 will not rotate with the screw 40, but the screw 40 will drive the moving locking block 38 to move closer to or away from the fixed locking block 37 in a straight line. When locking, the moving locking block 38 moves closer to the fixed locking block 37. The arc-shaped locking groove 39 of the movable locking block 38 presses against the first lead screw 23, thereby pressing the first lead screw 23 against the fixed locking block 37 and the movable locking block 38, thus restricting the rotational freedom of the first lead screw 23, and locking the position of the correction rolling sheet 5 to ensure that there is no accidental movement during the rolling process and to ensure the stability of the rolling. When it is necessary to adjust the axial position of the correction rolling sheet 5, the movable locking block 38 moves away from the first lead screw 23 and separates from the first lead screw 23, so that the first lead screw 23 can rotate normally. Thus, the correction rolling sheet 5 can be moved and adjusted by rotating the first lead screw 23. Similarly, the adjustment method of the forming rolling sheet 6 is the same as the adjustment method of the correction rolling sheet 5.By setting the indicator arrow 31, the first angle scale, and the second angle scale, the rotation angles of the first lead screw 23 and the second lead screw 26 are visualized. When the first lead screw 23 rotates one revolution, the correction sheet 5 moves a distance of one pitch, which is the pitch of the first lead screw 23. Similarly, when the second lead screw 26 rotates one revolution, the forming sheet 6 moves a distance of one pitch, which is the pitch of the second lead screw 26. Therefore, by controlling the rotation angles of the first lead screw 23 and the second lead screw 26, the movement distance of the correction sheet 5 and the forming sheet 6 can be precisely controlled, making the adjustment more accurate and still achieving a good texturing effect after adjustment.

[0035] In some embodiments, such as Figures 1 to 4 As shown, a bidirectional threaded screw 44 is rotatably installed inside the annular cavity 15. The bidirectional threaded screw 44 is radially parallel to the annular mounting base 3. Clamping and limiting plates 45 are threaded onto the two oppositely threaded sections of the bidirectional threaded screw 44. A limiting ring 46 is coaxially fixed to the bottom of the internal gear ring 16. The two clamping and limiting plates 45 are located on the outer and inner sides of the limiting ring 46, respectively. Friction plates 47 are fixed to the opposite end faces of the two clamping and limiting plates 45, and the bottom of the clamping and limiting plates 45 contacts the bottom of the annular cavity 15 to restrict the rotational freedom of the clamping and limiting plates 45. One end of the bidirectional threaded screw 44 protrudes from the outer wall of the annular mounting base 3 and is fixed with an adjusting nut. To prevent the three rolling plates in the rolling assembly from accidentally moving radially along the annular mounting base 3 during the rolling process, a... The locking mechanism of the internal gear ring 16 is as follows: when locking, the adjusting nut is turned by a wrench, which drives the bidirectional threaded screw 44 to rotate. Since the spiral directions of the two clamping limit plates 45 are opposite, the movement directions of the two clamping limit plates 45 are opposite. The two clamping limit plates 45 are respectively pressed against the outer ring and inner ring of the limit ring 46. The friction plate 47 increases the friction between the clamping limit plates 45 and the limit ring 46, thereby locking the rotational freedom of the limit ring 46, and thus locking the rotational freedom of the internal gear ring 16, so that the position of the adjusting seat 7 is locked and will not move radially along the annular mounting seat 3. In summary, before the texturing operation, it is necessary to ensure that the internal gear ring 16, the first screw 23 and the second screw 26 are locked so that the texturing forming assembly can stably perform the texturing operation.

[0036] In some embodiments, such as Figure 1 and Figure 9As shown, a cooling cylinder 48 is fixed on the corrugating machine base 1. The corrugating forming component is located between the drive base 49 and the cooling cylinder 48. An annular cooling cavity 50 is formed on the inner and outer walls of the cooling cylinder 48. Several cold air holes 51 are evenly opened on the inner wall of the cooling cylinder 48. The cold air holes 51 are connected to the annular cooling cavity 50. The cooling cylinder 48 is connected to a chiller through a pipe. After the cable is corrugated, it first passes through the cooling cylinder 48 and then is wound and stored. Since the cable is heated, in order to ensure that the performance of the cable sheath is not affected and that the subsequent processing of the cable is not affected, the cable sheath needs to be cooled in time. The chiller introduces cold air into the annular cooling cavity 50 of the cooling cylinder 48. The cold air is sprayed onto the cable sheath through the cold air holes 51, thereby cooling the cable and ensuring that the performance of the cable is not affected.
