Description

Technical Field

[0001] This invention relates to the field of drawing devices, and in particular to a drawing device for processing radio frequency feeder cables. Background Technology

[0002] Radio frequency (RF) cables are special cables used to transmit electromagnetic energy in the radio frequency band. They consist of an inner conductor, an outer conductor, and a supporting medium arranged coaxially. The inner conductor is generally made of copper-clad aluminum, copper tubing, or copper wire. Its characteristic impedance, transmission loss, and other key electrical parameters directly determine the signal transmission performance. In the production process of RF cables, the inner conductor needs to be stretched to the diameter required by the process to ensure electrical performance. Therefore, a special RF feeder cable processing and pulling device is required to complete this critical process.

[0003] During the drawing process of the inner conductor of the RF feeder cable, although the existing drawing equipment has the function of emergency production stop when the inner conductor breaks, after the wire breaks, the mold needs to be replaced. Usually, the mold is fixed on the processing table to avoid shaking during processing, which makes the mold replacement time long. As the inner conductor loses tension, it will sag and is very likely to come into contact with the processing table or surrounding parts, which will cause scratches on the surface of the inner conductor, structural deformation or impurity contamination, seriously reducing the subsequent processing accuracy of the inner conductor, and ultimately affecting the key electrical performance of the RF cable such as characteristic impedance and transmission loss. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a pulling device for processing radio frequency feeder cables.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A pulling device for processing radio frequency feeder cables includes two processing tables. A positioning shell is fixed in the middle of the two processing tables. An inner conductor is disposed in the middle of the positioning shell. A mold for processing the inner conductor is disposed between the positioning shell and the inner conductor. A lifting mechanism for driving the mold to move up and down is disposed between the positioning shell and the mold. The lifting mechanism includes a stepper motor fixed outside the positioning shell and an adjustment plate fixed inside the positioning shell. A protective frame for storing the mold is disposed on the side of the adjustment plate away from the processing table. A lifting mechanism for driving the protective frame to move up and down is disposed between the stepper motor and the adjustment plate. A wire clamping mechanism for clamping the inner conductor is disposed on the side of the protective frame. The wire clamping mechanism includes a first wire assembly for driving the inner conductor to move laterally and a second wire assembly for positioning the inner conductor.

[0007] In a preferred embodiment of the present invention, the lifting mechanism includes a transmission rod fixed to the output shaft of a stepper motor. A control lever is fixed to the end of the transmission rod away from the stepper motor. A main baffle and a secondary baffle are respectively provided at both ends of the control lever. A main slider is fixed to the end of the main baffle away from the control lever, and a secondary slider is fixed to the end of the secondary baffle away from the control lever. A cross groove is provided on the side of the adjustment disc near the control lever to facilitate the sliding of the main slider and the secondary slider. A secondary connecting rod is also fixed to the end of the main slider away from the control lever. The secondary connecting rod is Z-shaped, and the control lever is U-shaped. The main slider is positioned below the secondary slider. The end of the secondary connecting rod away from the main slider is fixed to the protective frame. The width of the main baffle and the secondary baffle is greater than the width of the stepper motor. The width of the cross-shaped slide groove is specified. A limiting groove is also provided in the middle of the cross-shaped slide groove. The limiting groove is cross-shaped. The main slider and the auxiliary slider are slidably connected in the cross-shaped slide groove. The auxiliary connecting rod passes through the limiting groove and is fixed to the outer wall of the protective frame. The output shaft of the stepper motor drives the transmission rod to rotate 90 degrees. The transmission rod drives the control lever to rotate 90 degrees. The control lever drives the main baffle and the auxiliary baffle to rotate. The main baffle drives the main slider to move vertically up and down in the cross-shaped slide groove. The auxiliary baffle drives the auxiliary slider to move horizontally in the cross-shaped slide groove. The main slider drives the auxiliary connecting rod to move from the bottom of the cross-shaped slide groove to the middle of the cross-shaped slide groove. The auxiliary connecting rod drives the protective frame to move from the inside of the positioning shell to the top of the positioning shell.

[0008] As a preferred embodiment of the present invention, a main connecting rod is fixed to the end of the auxiliary slider away from the auxiliary baffle. The end of the main connecting rod away from the auxiliary slider is connected to the first wire harness assembly. The main connecting rod is Z-shaped and is located between the auxiliary connecting rod and the adjusting plate. The auxiliary connecting rod passes through the limiting groove and is fixed to the first wire harness assembly. When the auxiliary slider moves laterally along the cross groove, the auxiliary connecting rod drives the first wire harness assembly to move along the outer wall of the inner conductor, causing the first wire harness assembly to move away from the protective frame.

[0009] As a preferred embodiment of the present invention, the first wire harness assembly includes a first wire harness block fixed to the end of the secondary connecting rod away from the secondary slider. Two first wire clamping plates are provided on the side of the first wire harness block near the protective frame. A support rod is also fixed to the bottom of the first wire harness block. The end of the support rod away from the first wire harness block is inserted into the interior of the positioning housing. The two first wire clamping plates are provided with grooves adapted to the inner conductor on their opposite sides. When the secondary connecting rod moves laterally, the secondary connecting rod drives the first wire harness block to move laterally, and the first wire harness block drives the first wire clamping plates to move laterally along the outer wall of the inner conductor.

[0010] As a preferred embodiment of the present invention, two first fixing rods are fixed between the first wire bundle block and the two first clamping plates, and two first springs are fixed between the first wire bundle block and the two first clamping plates. The two first clamping plates are inclinedly arranged on the side of the first wire bundle block near the protective frame. When the first wire bundle block drives the first clamping plates to move along the outer wall of the inner conductor, and the first wire bundle block drives the first clamping plates to move away from the protective frame, the two first clamping plates are affected by friction, which increases the gap between the two first clamping plates. The two first clamping plates move laterally along the outer wall of the inner conductor. When the first wire bundle block drives the first clamping plates to move towards the side closer to the inner conductor, the first clamping plates are affected by friction and the elastic force of the first springs, which causes the opposing sides of the two first clamping plates to contact each other, thus limiting the two first clamping plates to each other. The grooves opened in the first clamping plates drive the inner conductor and the two first clamping plates to move synchronously towards the side closer to the protective frame, so that the inner conductor is inserted into the interior of the mold.

[0011] As a preferred embodiment of the present invention, two insert rods are provided at the end of the first wire bundle block away from the first clamping plate. Two cleaning blocks for wiping dust from the surface of the inner conductor are provided at the ends of the two insert rods away from the first wire bundle block. Two threaded sleeves are rotatably connected to opposite sides of the two cleaning blocks. A limiting rod is also provided between the two cleaning blocks and the first wire bundle block. A threaded portion is provided on the side of the insert rod away from the first wire bundle block. The threaded portion is screwed onto the end of the threaded sleeve away from the cleaning block. The top of the two threaded sleeves is provided with insertion holes that are adapted to the limiting rods. By rotating the threaded sleeves, the threaded sleeves cooperate with the threaded portion, causing the two threaded sleeves to move to opposite sides, so that the two cleaning blocks fit together, and the outer wall of the inner conductor is wiped by the two cleaning blocks.

[0012] As a preferred embodiment of the present invention, the second wire harness assembly includes two second wire harness blocks sleeved on the outside of the inner conductor. Two second wire clamping plates are provided on the side of the two second wire harness blocks away from the protective frame to clamp the inner conductor. Two second fixing rods and two second springs are also provided between the two second wire harness blocks. The two second wire clamping plates are provided with positioning slots adapted to the inner conductor on the opposite side. When the two first wire clamping plates drive the inner conductor to move laterally, the inner conductor passes through the second wire harness blocks and the second wire clamping plates. The elastic force of the second springs pulls the two second wire clamping plates to move to the opposite side, so that the positioning slots of the two second wire clamping plates clamp the inner conductor, thereby fixing the inner conductor.

[0013] As a preferred embodiment of the present invention, a blocking block is further provided below the two second wire bundle blocks. The blocking block is fixed on the side of the positioning housing away from the support rod. A lifting plate is inserted in the middle of the blocking block. Two wedge blocks are fixed on the top of the lifting plate. The bottom of the two second wire bundle blocks is provided with wedge grooves that are adapted to the wedge blocks. A locking rod for positioning the lifting plate is also provided on the side of the blocking block. Several locking holes adapted to the locking rod are provided in the middle of the lifting plate. Pulling the locking rod moves the locking rod to the outside of the blocking block. The lifting plate moves downward under the influence of gravity. The lifting plate drives the wedge blocks to move downward. The wedge blocks separate from the second wire bundle blocks, and the two second wire bundle blocks are disassembled from the outside of the inner conductor, which facilitates the subsequent cleaning and daily maintenance of the second wire bundle blocks.

[0014] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0015] 1. This invention, through the cooperation of a lifting mechanism, a first wire assembly, an adjusting disc, a transmission rod, a control rod, a main baffle, a main slider, and a first wire clamping plate, moves the protective frame from the bottom to the top of the outer shell, directly expanding the operating space around the mold, significantly shortening the time spent on mold replacement and maintenance, reducing equipment downtime, and the first wire clamping plate can effectively clamp the inner conductor after the wire breaks, preventing the inner conductor from drooping due to loss of tension, preventing it from contacting the processing table and surrounding parts, causing surface scratches, structural deformation, and impurity contamination, and ensuring the stability of the subsequent processing accuracy of the inner conductor;

[0016] 2. This invention adjusts the relative distance between the broken part of the inner conductor and the clamping plate through the cooperation of structures such as the secondary baffle, secondary slider, secondary connecting rod, first wire bundle block and first clamping plate, avoiding docking difficulties caused by the positional offset of the broken end, so that the staff does not need to adjust the posture of the inner conductor, and directly prepares the positioning for subsequent insertion of a new mold, reducing the complexity of operation.

[0017] 3. Through the cooperation of the first wire assembly, the second wire assembly, the first clamping plate and the second clamping plate, the present invention can intermittently fix and move the broken inner conductor. When fixed, it can firmly clamp the inner conductor to prevent shaking and scratching. When moved, it only drives the inner conductor to move smoothly, avoiding the roughness and deformation of the broken end of the inner conductor caused by continuous hard pulling or movement without fixation. It ensures that the inner conductor always maintains a regular shape, laying the foundation for subsequent insertion of new molds and maintaining the pulling accuracy, without affecting the characteristic impedance and transmission loss of the radio frequency cable.

[0018] 4. Through the cooperation of the first wire bundle block, insert rod, threaded sleeve, cleaning block and support rod, the present invention allows the cleaning block to adhere to the outer wall of the inner conductor to wipe away dust, effectively removing dust, oil and other impurities attached to the surface of the inner conductor after wire breakage. This prevents these impurities from getting stuck in the gap between the mold and the inner conductor when the inner conductor is inserted into the new mold, causing surface scratches or accelerating the wear of the inner wall of the mold, thereby maintaining the surface smoothness and diameter accuracy of the inner conductor after drawing, and ensuring the quality of subsequent processing.

[0019] 5. Through the cooperation of the second wire assembly, the second wire block, the second fixing rod, the second spring and the second clamping plate, the present invention can quickly clamp the inner conductor at the moment the inner conductor breaks after stretching, effectively preventing the inner conductor from falling due to loss of tension, avoiding surface scratches and structural deformation caused by contact with the processing table, mold or surrounding parts, and reducing the product defect rate.

[0020] 6. This invention, through the cooperation of structures such as the second wire bundle block, lifting plate, blocking block and locking rod, can directly and quickly separate the two second wire bundle blocks from the outside of the inner conductor without disassembling the overall structure of the device or using complex tools, thus greatly shortening the disassembly time.

The auxiliary baffle 508 drives the auxiliary slider 509 to move horizontally in the cross slide groove. The main slider 507 drives the auxiliary connecting rod 511 from the bottom of the cross slide groove to the middle of the cross slide groove. The auxiliary connecting rod 511 drives the protective frame 503 from the inside of the positioning shell 2 to the top of the positioning shell 2.

[0038] refer to Figure 4 , Figure 5 and Figure 6As shown, a main connecting rod 510 is fixed to one end of the auxiliary slider 509 away from the auxiliary baffle 508. The end of the main connecting rod 510 away from the auxiliary slider 509 is connected to the first wire harness assembly 61. The main connecting rod 510 is Z-shaped and is located between the auxiliary connecting rod 511 and the adjusting plate 502. The auxiliary connecting rod 511 passes through the limiting groove and is fixed to the first wire harness assembly 61. When the auxiliary slider 509 moves laterally along the cross groove, the auxiliary connecting rod 511 drives the first wire harness assembly 61 to move along the outer wall of the inner conductor 3, causing the first wire harness assembly 61 to move away from the protective frame 503.

[0039] refer to Figure 7 , Figure 8 and Figure 9 As shown, the protective frame 503 is also provided with a wire clamping mechanism 6 for clamping the inner conductor 3 on its side. The wire clamping mechanism 6 includes a first wire assembly 61 that drives the inner conductor 3 to move laterally. The first wire assembly 61 includes a first wire block 611 fixed to the end of the auxiliary connecting rod 511 away from the auxiliary slider 509. Two first wire clamping plates 614 are provided on the side of the first wire block 611 near the protective frame 503. A support rod 618 is also fixed to the bottom of the first wire block 611. The end of the support rod 618 away from the first wire block 611 is inserted into the inside of the positioning housing 2. The two first wire clamping plates 614 are provided with grooves that are adapted to the inner conductor 3 on the opposite side.

The two first clamping plates 614 are inclinedly arranged on the side of the first wire bundle block 611 near the protective frame 503. When the first wire bundle block 611 drives the first clamping plates 614 to move along the outer wall of the inner conductor 3, and the first wire bundle block 611 drives the first clamping plates 614 to move away from the protective frame 503, the two first clamping plates 614 are affected by friction, causing the two first clamping plates 614 to move away from the protective frame 503. The gap between the first clamping plates 614 increases, and the two first clamping plates 614 move laterally along the outer wall of the inner conductor 3. When the first bundle of wires 611 drives the first clamping plates 614 to move closer to the inner conductor 3, the first clamping plates 614 are affected by friction and the elastic force of the first spring 613, causing the opposing sides of the two first clamping plates 614 to contact each other, thus limiting the two first clamping plates 614 to each other. Through the groove opened in the first clamping plates 614, the inner conductor 3 and the two first clamping plates 614 move synchronously to the side closer to the protective frame 503, so that the inner conductor 3 is inserted into the interior of the mold 4.

The insertion rod 615 is provided with a threaded part on the side away from the first wire bundle block 611. The threaded part is screwed to the end of the threaded sleeve 616 away from the cleaning block 617. The top of the two threaded sleeves 616 is provided with insertion holes that are adapted to the limit rod 619.

When the two clamping plates 614 drive the inner conductor 3 to move laterally, the inner conductor 3 passes through the second wire blocks 621 and the second clamping plates 624. The elastic force of the second springs 623 pulls the two clamping plates 624 to move to the opposite side, so that the positioning slots of the two clamping plates 624 clamp the inner conductor 3, thereby fixing the inner conductor 3.

[0045] refer to Figure 10 and Figure 11As shown, a blocking block 626 is also provided below the two second wire bundle blocks 621. The blocking block 626 is fixed on the side of the positioning housing 2 away from the support rod 618. A lifting plate 625 is inserted in the middle of the blocking block 626.

A locking rod 627 for positioning the lifting plate 625 is also provided on the side of the blocking block 626. Several locking holes that match the locking rod 627 are provided in the middle of the lifting plate 625. Pulling the locking rod 627 moves the locking rod 627 to the outside of the blocking block 626. The lifting plate 625 moves downward under the influence of gravity. The lifting plate 625 drives the wedge blocks to move downward. The wedge blocks separate from the second wire bundle blocks 621, and the two second wire bundle blocks 621 are disassembled from the outside of the inner conductor 3, which facilitates the subsequent cleaning and daily maintenance of the second wire bundle blocks 621.

[0046] The two first clamping plates 614 drive the inner conductor 3 to move laterally. The inner conductor 3 passes through the second bundle block 621 and the second clamping plate 624. The elastic force of the second spring 623 pulls the two second clamping plates 624 to move to opposite sides, so that the positioning slots of the two second clamping plates 624 clamp the inner conductor 3, thereby fixing the inner conductor 3.

The control lever 505 drives the main baffle 506 and the auxiliary baffle 508 to rotate. The main baffle 506 drives the main slider 507 to move vertically up and down along the cross groove. The auxiliary baffle 508 drives the auxiliary slider 509 to move horizontally along the cross groove. The main slider 507 drives the auxiliary connecting rod 511 from the bottom of the cross groove to the middle of the cross groove. The auxiliary connecting rod 511 drives the protective frame 503 from the inside of the positioning shell 2 to the top of the positioning shell 2, which facilitates the quick replacement of the mold 4.

[0049] Simultaneously, when the first wire bundle block 611 drives the first clamping plate 614 to move along the outer wall of the inner conductor 3, and the first wire bundle block 611 drives the first clamping plate 614 to move away from the protective frame 503, the two first clamping plates 614 are affected by friction, which increases the gap between the two first clamping plates 614. The two first clamping plates 614 move laterally along the outer wall of the inner conductor 3. When the first wire bundle block 611 drives the first clamping plate 614 to move closer to the inner conductor 3, the first clamping plate 614 is affected by friction and the elastic force of the first spring 613, which causes the opposing sides of the two first clamping plates 614 to contact each other, thus limiting the two first clamping plates 614 to each other. Through the groove opened in the first clamping plate 614, the inner conductor 3 and the two first clamping plates 614 move synchronously to the side closer to the protective frame 503, so that the inner conductor 3 is inserted into the interior of the mold 4.

[0050] The two first clamping plates 614 drive the inner conductor 3 to move laterally. The inner conductor 3 passes through the second bundle block 621 and the second clamping plate 624. The elastic force of the second spring 623 pulls the two second clamping plates 624 to move to the opposite side, so that the positioning slots of the two second clamping plates 624 clamp the inner conductor 3, thereby fixing the inner conductor 3.

[0051] Finally, pull the locking lever 627 to move it to the outside of the blocking block 626. The lifting plate 625 moves downward under the influence of gravity, and the lifting plate 625 drives the wedge block to move downward. The wedge block separates from the second wire bundle block 621, and the two second wire bundle blocks 621 are disassembled from the outside of the inner conductor 3, which facilitates the subsequent cleaning and daily maintenance of the second wire bundle blocks 621.

[0052] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
