Before actual use, rust, oxide scale, etc. will appear on the surface of the plate and strip, and the surface of the plate and strip needs to be brushed by a brush roller.

[0015] Preferably, the wire folding cavity has a guide assembly for guiding the wire to pass into the wire hole, the guide assembly includes two opposing guide plates, a guide groove for guiding the wire to pass into the wire hole is formed between the two guide plates, a guide drive is connected to one of the guide plates, when the upper wire folding part and the lower wire folding part act on the two strands of wire to pass into the wire hole respectively, the guide drive drives the corresponding guide plate to move in a radial direction away from the brush disc, so that the corresponding guide plate is away from the other guide plate to avoid the two strands of wire overlapping each other; while guiding the wire to pass into the wire hole, the guide assembly takes into account the problem of the guide plate avoiding the strands of wire when folding the wire, to prevent the two strands of wire from interfering with the guide plate when folded.

[0019] The wire folding member in the present invention has a wire folding end, and the wire folding end is divided into an upper wire folding part and a lower wire folding part by the strip groove used to accommodate the brush plate. After the wire hole of the brush plate is inserted into the wire hole, the wire folding member is driven to move by the driving assembly, so that the upper wire folding part and the lower wire folding part fold the stranded wire on both sides of the brush plate outward. The upper wire folding part and the lower wire folding part are equivalent to two "fingers" for folding the stranded wire outward. The operation is simple and labor-saving, and workers do not need to fold the wire repeatedly, thereby improving the wire folding efficiency.

[0020] Under ideal conditions, when the upper and lower wire folding parts act on the separated wire strands, the upper push-pull assembly and the lower push-pull assembly need to move, and extend the movable pressure rod on the wire pressing disk to compress the separated wire strands; but under actual conditions, if a single driving cylinder is used to drive the wire folding parts, it is difficult for the upper and lower push-pull cylinders to move completely synchronously with the single driving cylinder, which can easily cause the wire folding ends to collide and interfere with the movable pressure rod. Therefore, the driving assembly in the present invention includes a first driving cylinder and a second driving cylinder for driving the wire folding parts to move in steps, so that the wire folding parts move first and make room for the movable pressure rod to extend outward. After the movable pressure rod compresses the separated wire strands, the wire folding parts continue to move and completely separate from the wire bundle, thereby ensuring that the wire folding work is carried out normally.

[0021] The piston rod of the first driving cylinder and the piston rod of the second driving cylinder are opposite to each other and connected to each other. This design can save layout space while ensuring that the first driving cylinder or the second driving cylinder can leverage each other and form a step-by-step drive for the folded wire piece when it is in action. The design is ingenious and kills two birds with one stone. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0025] The specific implementation methods of the present invention are as follows: like Figure 1-9 As shown, this embodiment provides a tow fixing device, comprising: The brush plate 9 has a plurality of wire holes 91 evenly distributed along the circumferential direction on the end surface of the brush plate 9. A predetermined length of wire is passed through the wire holes 91. The wire is divided by the brush plate 9 into two strands of wire located at the upper and lower sides of the brush plate 9. The plurality of wire holes 91 form a pair of areas on the end surface of the brush plate 9. The wire pressing assembly 63 includes two wire pressing discs 631 located on both sides of the brush disc 9 and matched in the corresponding matching area up and down. A plurality of radial slide grooves 631b corresponding to the wire holes 91 are evenly distributed on the outer circumference of the wire pressing disc 631. A movable pressure rod 633 is slidably connected in the radial slide groove 631b. A radial guide groove 632 is provided on the end surface of the wire pressing disc 631 facing away from the brush disc 9. A protrusion 634 is connected to the movable pressure rod 633. The protrusion 634 is slidably connected in the radial guide groove 632 and exceeds the corresponding end surface of the brush disc 9. Push-pull mechanism; the push-pull mechanism includes an upper push-pull assembly 34 and a lower push-pull assembly 35 respectively located on the upper and lower sides of the brush plate 9, the upper push-pull assembly 34 includes an upper push-pull member 341, and the upper push-pull member 341 is connected to an upper driving member; the lower push-pull assembly 35 includes a lower push-pull member 351, and the lower push-pull member 351 is connected to a lower driving member; the upper driving member and the lower driving member can respectively drive the upper push-pull member 341 and the lower push-pull member 351 to move synchronously in a radial direction away from or close to the brush plate 9; the upper push-pull member 341 and the lower push-pull member 351 are located on the inner side of the corresponding protrusion 634; When the two strands of wire are overlapped outward to form a wire bundle 8, the upper push-pull member 341 and the lower push-pull member 351 move synchronously in the radial direction away from the brush plate 9 and act on the protrusion 634, so that the movable pressure rod 633 extends radially and presses the two strands of wire, thereby fixing the wire bundle 8.

[0026] Furthermore, it also includes a support frame 3, an upper push-pull assembly 34 and a lower push-pull assembly 35 are arranged on the support frame 3, and in order to facilitate the folding of the wire inserted into the wire hole 91 outward, there is a folding wire assembly 37 arranged on the support frame 3 between the upper push-pull assembly 34 and the lower push-pull assembly 35, and the folding wire assembly 37 includes a driving assembly and a folding wire member 371, and the folding wire member 371 has a folding wire end at the head, and a strip groove 375 extending laterally to the inner side of the folding wire member 371 for allowing the brush plate 9 to be inserted is provided on the folding wire end, and the folding wire member 371 has a strip groove 375 for corresponding to the wire hole 91 on the brush plate 9. The wire folding cavity passes through the wire folding piece 371 from top to bottom, so that the material wire can be inserted into the corresponding wire hole 91 along the longitudinal direction; the strip groove 375 divides the wire folding end into an upper wire folding part 375a and a lower wire folding part 375b; the driving assembly can drive the wire folding piece 371 to move in a radial direction away from the brush plate 9, so that the upper wire folding part 375a and the lower wire folding part 375b respectively act on the two strands of material wire inserted into the wire hole 91, so as to stack the two strands of material wire outwardly into a wire bundle 8; the whole operation process is simple and labor-saving, eliminating the process of manually stacking the wire bundle 8, and improving the work efficiency of the wire folding process.

[0027] Furthermore, the specific structure of the wire folding assembly 37 is as follows: the wire folding assembly 37 includes a linkage assembly, which includes a first support plate 374a and a second support plate 374b spaced apart, a first cross bar 377 is connected between the first support plate 374a and the second support plate 374b, and the wire folding member 371 is arranged on the first support plate 374a; in an ideal state, when the upper wire folding portion 375a and the lower wire folding portion 375b act to separate the strands of the wire, the upper push-pull assembly 34 and the lower push-pull assembly 35 need to be moved, and the movable pressing rod 633 on the wire pressing disk 631 is extended. In order to compress the divided wire strands; however, in actual conditions, if a single driving cylinder is used to drive the wire folding member 371, it is difficult for the upper push-pull cylinder 342 and the lower push-pull cylinder 353 to move completely synchronously with the single driving cylinder, which may easily cause the wire folding end to collide and interfere with the movable pressure rod 633. Therefore, the driving assembly in this embodiment includes a first driving cylinder 376 and a second driving cylinder 379 for acting on the second support plate 374b. The first driving cylinder 376 and the second driving cylinder 379 drive the wire folding member 371 to move in a step-by-step manner. Specifically, the first The piston rod of the driving cylinder 376 is extended and retracted and drives the wire folding member 371 to move in the radial direction away from the brush plate 9, so as to make room for the movable pressure rod 633 to extend in the radial direction; at this time, the wire folding member 371 is not completely separated from the wire bundle 8; when the movable pressure rod 633 extends and presses the stranded wire, the piston rod of the second driving cylinder 379 is extended and retracted and drives the wire folding member 371 to continue to move in the radial direction away from the brush plate 9, so that the wire folding member 371 is completely separated from the wire bundle 8; the first driving cylinder 376 and the second driving cylinder 379 of this design can be used to control the second support plate 3 74b forms a step-by-step drive to compensate for the response time difference between the drive assembly and the upper push-pull cylinder 342 and the lower push-pull cylinder 353, so that when the piston rod of the first drive cylinder 376 is extended and retracted to make room for the corresponding movable pressure rod 633, the two strands of wire are still stuck in the strip groove 375 of the wire folding member 371 instead of spreading outwards. After the movable pressure rod 633 compresses the strands of wire, the piston rod of the second drive cylinder 376 is extended and retracted to completely disengage from the formed wire bundle 8, ensuring that after the wire folding mechanism is finished, the corresponding movable pressure rod 633 can smoothly compress the wire bundle.

[0028] Furthermore, the wire hole 91 of the brush disc 9 is close to the outer peripheral edge of the brush disc 9, so that the two strands of wire can be folded in half to form a wire bundle 8 that extends beyond the outer periphery of the brush disc, and after the wire bundle 8 is formed, the length of the stranded wire attached to the end surface of the brush disc 9 is smaller than the length of the stranded wire that extends beyond the brush disc 9. Therefore, to correspond to these two lengths, the telescopic stroke of the piston rod of the first drive cylinder 376 is smaller than the telescopic stroke of the piston rod of the second drive cylinder 379. Specifically, when the piston rod of the first drive cylinder 376 is telescoped and drives the wire folding member 371 to move in a radial direction away from the brush disc 9 and make room for the movable pressure rod 633 to extend radially, the wire folding end only needs to just leave the end surface of the brush disc 9, so the movable range of the wire folding member 371 is shorter at this time; afterwards, the wire folding member 371 needs to completely separate from the wire bundle 8, and the required movable range is longer, so the telescopic length of the piston rod of the second drive cylinder 379 is longer.

[0029] Furthermore, if the first drive cylinder 376 and the second drive cylinder 379 are arranged side by side to drive the folding wire member 371 in steps, then when the first drive cylinder 376 or the second drive cylinder 379 is extended or retracted, the piston rod of the other cylinder will inevitably be driven to move, affecting the smoothness of the movement of the folding wire member 371. Therefore, in order to meet the purpose of driving the folding wire member 371 in steps, the first drive cylinder 376 is arranged on the first support plate 374a, and the second drive cylinder 379 is arranged on the first longitudinal plate 378 close to the side of the first support plate 374a, and the piston rod of the first drive cylinder 376 and the piston rod of the second drive cylinder 379 are relative and connected together; specifically, there is a shaft sleeve between the piston rod of the first drive cylinder 376 and the piston rod of the second drive cylinder 379, and the piston rod of the first drive cylinder 376 and the piston rod of the second drive cylinder 379 are inserted into the shaft sleeve and locked by screws; thereby, while satisfying the step-by-step drive of the folding wire member 374, the layout space of the drive component is saved.

[0030] Furthermore, at the outer peripheral position of the wire pressing disk 631, a limiting portion 631a is formed between every two adjacent radial slide grooves 631b, and the movable pressure rod 633 has two opposite side extension portions 633a on both sides. When the movable pressure rod 633 is retracted, the two side extension portions 633a are abutted against the corresponding limiting portions 631a to prevent the entire movable pressure rod 633a from being completely retracted into the radial slide groove 631b.

[0031] Furthermore, the bottom end of the movable pressure rod 633 has a limiting groove 635. After the movable pressure rod 633 is extended, the stranded wire is within the limitation of the limiting groove 635, thereby preventing the stranded wire from spreading to both sides.

[0032] Furthermore, a plurality of weight-reducing holes 631c are provided on the end surface of the wire pressing disc 631 and are evenly distributed along the circumferential direction, so that the structure of the entire wire pressing disc 631 is lightweight.

[0033] Furthermore, the wire folding mechanism in the present embodiment needs to pass the material wire from top to bottom into the wire hole 91 of the brush plate 9 corresponding to the wire folding cavity before folding the wire. The wire threading method can be manual threading or equipment-assisted threading. The wire threading method assisted by equipment is adopted in the present embodiment to pull the material wire into the wire hole 91. Specifically, an alternating wire transport mechanism 33 is provided above the support frame 3. The alternating wire transport mechanism 33 includes an upper wire transport mechanism 31 and a lower wire transport mechanism 32. The upper wire transport mechanism 31 includes an upper wire transport block and an upper wire transport cylinder that drives the upper wire transport block to move up and down. The upper wire transport block has a first guide groove for threading the material wire, and the upper wire transport block is provided with an upper clamping cylinder. The piston rod of the upper clamping cylinder passes through the first guide groove to clamp the material wire; the lower wire transport mechanism 32 includes a lower wire transport block and a lower wire transport cylinder that drives the lower wire transport block to move up and down. The first guide groove corresponds to the second guide groove, and the lower wire transport block is provided with a lower clamping cylinder, the piston rod of the lower clamping cylinder penetrates into the second guide groove to clamp the wire; the lower end of the second guide groove is connected with a catheter, and the catheter is located above the wire folding cavity of the wire folding piece 371 to correspond to the corresponding wire hole 91 on the brush plate 9; the support frame 3 is provided with an avoidance hole 343 to avoid the movement of the catheter; when transporting the wire, the piston rod of the lower clamping cylinder extends out and clamps the wire, and then the lower wire transport cylinder drives the lower wire transport block and the catheter to move to the vicinity of the wire folding cavity to prepare for wire transport; when transporting the wire, the piston rod of the upper clamping cylinder extends out and clamps the wire, and under the drive of the upper wire transport cylinder, a small length of the wire is transported downward, and then the piston rod of the lower clamping cylinder extends out and clamps the wire, the piston rod of the upper clamping cylinder retracts and resets upward, alternating back and forth until the wire of a predetermined length is inserted into the wire hole 91.

[0034] Furthermore, after the wire transportation is completed, it is necessary to use the wire cutting mechanism 36 on the support frame 3 to cut the wire of a predetermined length that passes through the wire hole 91; specifically, the wire cutting mechanism 36 includes a fixed cutter 361 and a movable cutter 363 that are arranged on the support frame 3 and correspond to the position of the wire. The movable cutter 363 is driven by a wire cutting cylinder 362 arranged on the support frame 3. When the wire of a predetermined length passes through the wire hole 91, the wire cutting cylinder 362 controls the movable cutter 362 to approach the fixed cutter 361 to cut the wire between the fixed cutter 361 and the movable cutter 363.

[0035] Further, after the wire threading and wire cutting are completed, the wire folding member 371 needs to be driven by the driving assembly and fold the two strands of wire. To ensure that the wire folding member 371 can move stably in the horizontal direction, the wire folding member 371 is connected to a first support plate 374a, and the first support plate 374a is connected to a first guide assembly. The first guide assembly includes a first longitudinal plate 378 arranged on the support frame 3, and the first longitudinal plate 378 is provided with a first guide hole. A first guide hole is slidably connected to the first support plate 374a. A cross bar 377, specifically, two first guide holes are arranged at intervals on the first longitudinal plate 378, and the two first cross bars 377 are inserted into the corresponding first guide holes; the driving component drives the first cross bar 377 to slide in the first guide hole, thereby driving the wire folding member 371 to move in the radial direction away from the brush plate 9; the first guide component can provide active guidance for the wire folding member 371, so that the upper wire folding part 375a and the lower wire folding part 375b of the wire folding member 371 can stably bend the two strands of material wire inserted into the wire hole 91.

[0036] Furthermore, when threading the wire, since the wire extending out of the conduit is still at a certain distance from the wire hole 91 in the wire folding cavity of the wire folding member 371, in order to prevent the wire extending out of the conduit from spreading, the wire folding cavity is provided with a guide assembly for guiding the wire to pass through the wire hole 91, and the guide assembly includes two opposing guide plates 372, and a guide groove 373 for guiding the wire to pass through the wire hole 91 is formed between the two guide plates 372, and one of the guide plates 372 is connected to a guide drive member, and the guide drive member is a guide cylinder 374, and the piston rod of the guide cylinder 374 passes through the wire folding cavity and is connected to the corresponding guide plate 372; the piston rod of the guide cylinder 374 has a fast extension speed and a sensitive response, and has a good driving effect on the corresponding guide plate 372; in this embodiment, one of the stationary guide plates 372 is connected to the inner side of the wire folding end, The guide plate 372 connected to the guide drive is connected to the piston rod of the guide cylinder 374.
