Description

Technical Field

[0001] This invention relates to the field of stranding machine technology, and more specifically to stranding machines for large-section cables. Background Technology

[0002] A wire stranding machine is a mechanical device used to twist multiple wires together in a certain pattern. It is widely used in the wire and cable processing industry. Its main function is to twist multiple wires into a single strand to meet the process requirements of cables. It is one of the main pieces of equipment in wire harness production and processing.

[0003] Traditional stranding machines can only process cables with small cross-sectional areas, not those with large cross-sectional areas. A traditional stranding machine consists of a rotating stranding head and clamps, symmetrically positioned. The cable head is fixed to the stranding head, and the end is fixed to the clamp. If the cable's cross-sectional area is too large, the stress is concentrated at the cable's front end. During processing, this localized stress is unstable, resulting in inconsistent and significant differences in the strand pitch, affecting the overall stability of the stranded cable and reducing the overall quality of the process. Summary of the Invention

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] For stranding machines for large square cables, please refer to [link / reference]. Figure 1-8 As shown, it includes: a stranded wire head 100, a first drive device 200, a track 300, a wire clamp assembly 400, a movable platform assembly 500, a second drive device 600, and a cabinet 800.

[0024] The stranded head 100 has a clamping groove 101 for clamping the cable 00. The stranded head 100 is driven to rotate by the first driving device 200. The stranded head 100 mainly serves to clamp the cable 00. At the same time, when the stranded head 100 rotates, it realizes the twisting between multiple cables 00.

[0025] Track 300 extends horizontally outward; The wire clamp assembly 400 can clamp the cable 00. The wire clamp assembly 400 is installed on the track 300 and can move linearly along the track 300. The wire clamp assembly 400 mainly serves to clamp the cable 00. The above-mentioned twisted wire head 100 is the front end that clamps the cable 00, while the wire clamp assembly 400 is the end that clamps the cable 00.

[0026] The movable platform assembly 500 is mounted on the track 300 and driven to move linearly along the track 300 by the second drive device 600. The movable platform assembly 500 is provided with a cable hole 501 for the cable 00 to pass through. like Figure 1 As shown, the twisted wire head 100, the wire clamp assembly 400 and the movable table assembly 500 are arranged in a straight line. When large square cables need to be twisted, the front end of the large square cable is clamped to the twisted wire head 100 and the end is clamped to the wire clamp assembly 400. During the process of the first drive device 200 driving the stranded head 100 to rotate, the second drive device 600 drives the movable table assembly 500 along... Figure 1 Moving in the direction of the arrow, since cable 00 passes through the cable hole 501 of the movable table assembly 500, the movable table assembly 500 restricts cable 00. When cable 00 rotates, the main thing is to first twist the part of the cable between the twisted head 100 and the movable table assembly 500. During the uniform rotation of the stranded wire head 100, the movable table assembly 500 moves at a uniform speed in the direction of the arrow, thus achieving uniform twisting pitch of the cable during stranding. If the twist pitch needs to be adjusted, the moving speed of the movable table assembly 500 can be adjusted. With the rotation speed of the twisted wire head 100 remaining constant, the greater the moving speed of the movable table assembly 500, the greater the twist pitch, and the smaller the moving speed of the movable table assembly 500, the smaller the twist pitch.

[0027] Here, twist pitch refers to the distance between two twisted points on the cable.

[0028] In one implementation, such as Figure 7-8 As shown, the stranded head 100 includes: a rotating member 110 with a toothed ring 111, a first component 120 fixedly assembled to the rotating member 110, and a second component 130 installed on the first component 120. The first component 120 is provided with a U-shaped groove, and the second component 130 is installed in the U-shaped groove, so that the clamping groove 101 is formed between the first component 120 and the second component 130.

[0029] Specifically, such as Figure 8 As shown, the rotating component 110 is arranged in a ring shape, and a toothed ring 111 is provided on its back side. The first component 120 is fixedly installed on the rotating component 110 and rotates with the rotating component 110. The first component 120 has a U-shaped groove 121 in its middle, and the second component 130 is also U-shaped. The cross-sectional area of ​​the second component 130 is smaller than the cross-sectional area of ​​the U-shaped groove 121. Figure 7 As shown, after the second component 130 is installed in the U-shaped groove 121, it also forms the clamping groove 101; Furthermore, the stranded head 100 also includes: a screw 140 passing through the first component 120 and the second component 130 and a handle 150 for mounting the top of the screw 140. The handle 150 pulls the screw 140 upward, causing the second component 130 to move upward to clamp the cable 00. After the front end of the cable 00 is inserted into the clamping groove 101, the second component 130 is pulled up by the screw 140 to clamp the cable 00. Then, the handle 150 is pressed down to lock the screw 140, thus locking the second component 130 and finally keeping the cable 00 clamped.

[0030] In one embodiment, the first drive device 200 is a speed reducer; the first drive device 200 includes: a motor 210 and a gear 220, the gear 220 is connected to the output shaft of the motor, and the gear 220 meshes with the gear ring 111 to drive the stranded head 100 to rotate.

[0031] In one implementation, such as Figure 5 As shown, the wire clamp assembly 400 includes: a first slider 410, a first bracket 420 mounted on the first slider 410, and at least two wire clamps 430 mounted on the first bracket 420. The wire clamps 430 can clamp the end of the cable 00. The first slider 410 is mounted on the track 300. During the twisting process of the cable 00, the straight length of the cable 00 will become shorter. Therefore, during the twisting process, the reverse force of the cable 00 pulls the wire clamp assembly 400 to move along the track 300, that is, to move towards the twisted end 100.

[0032] Furthermore, during the cable 00's winding process, although the movable platform assembly 500 limits the twisted portion of the cable, some stress still acts on the portion of the cable between the movable platform assembly 500 and the clamp assembly 400. Therefore, this technical solution sets the clamp 430 as a rotatable structure, and the rotation of the clamp 430 can release the stress from the cable 00.

[0033] Specifically, such as Figure 5 As shown, the wire clamp 430 is rotatably mounted on the first bracket 420 via the bearing 431; The wire clamp 430 can be a manual wire clamp, and the wire clamp 430 can use existing technology.

[0034] Furthermore, the clamp assembly 400 also includes a damper 442 with a meshing gear 441 mounted on the first bracket 420; Continue as Figure 5 As shown, the damper 442 is mounted on the side of the first bracket 420, and the shaft of the meshing gear 441 is set horizontally. like Figure 2 and Figure 3 As shown, a rack 310 is provided parallel to the track 300, and the meshing gear 441 of the damper 442 meshes with the rack 310; During the stranding process, when the wire clamp 430 receives tension from the cable 00, the wire clamp assembly 400 moves along the track 300 toward the stranding head 100, and the meshing gear 441 rotates during the movement. In conventional technology, a tension spring is provided on the first support 420. When the wire clamp assembly 400 moves toward the twisting head 100, the tension spring is stretched. After the twisting is completed and the wire clamp 430 releases the cable 00, the tension from the cable 00 disappears, and the wire clamp assembly 400 resets under the elastic force of the tension spring. At the moment of reset, the wire clamp assembly 400 moves quickly along the track 300 and finally impacts the end of the track 300. In this way, during the rapid twisting process, the wire clamp assembly 400 is prone to move along the track 300 and rush forward toward the twisting head 100. After the twisting is completed, the track 300 and the wire clamp assembly 400 are easily damaged by the reset impact. Therefore, this technical solution replaces the traditional tension spring with a damper 442 with a meshing gear 441. During the stranding process, due to the damping effect of the damper 442, under the tension of the cable 00, the clamp assembly 400 moves towards the stranding head 100 at a buffered and uniform speed, avoiding rushing out towards the stranding head 100. After the stranding is completed, the clamp assembly 400 will not quickly reset and hit the end of the track 300. The user only needs to apply force to push the clamp assembly 400 to slowly move towards the end of the track 300 to reset.

[0035] In one implementation, such as Figure 6 As shown, the movable platform assembly 500 includes: a second slider 510, an adjusting block 520, and a second support 530. The adjusting block 520 is arranged in an I-shape such that the wire holes 501 are formed on both sides of the adjusting block 520 respectively.

[0036] Specifically, during the cable routing process, a cable passes through a cable routing hole 501, which limits the cable 00 and ultimately achieves the twisted cable routing.

[0037] In one embodiment, the second drive device 600 includes a servo motor 610 and a belt drive assembly 620, wherein the belt 621 of the belt drive assembly 620 is arranged along the length direction of the track 300, and the second bracket 530 is fixed to the belt 621. The belt drive assembly 620 includes a belt 621, a drive gear, and a driven gear. The belt 621 is wound between the drive gear and the driven gear. The drive gear is located at the beginning of the track 300, and the driven gear is located at the end of the track 300. The drive gear is mounted on the output shaft of the servo motor 610 to realize transmission.

[0038] like Figure 1 As shown, the track 300 is provided with two symmetrical tracks. The belt drive assembly 620 is installed on the right track 300, and the rack 310 is installed on the left track 300. The second bracket 530 is fixed to the belt 621, so when the belt 621 rotates, it drives the movable table assembly 500 to move. The servo motor 610 can be a forward and reverse motor. When rotating forward, the movable table assembly 500 moves toward the wire clamp assembly 400, and when rotating in reverse, the movable table assembly 500 moves toward the twisted wire head 100.

[0039] In one embodiment, the system further includes: a cabinet 800 and a protective cover 700; the protective cover 700 is provided corresponding to the track 300; the first drive device 200 and the servo motor 610 are installed inside the cabinet 800, and the twisted wire head 100 is installed in the cabinet 800.

[0040] Both the 800 cabinet and the 700 protective cover serve a protective function.

[0041] In addition, the 800 rack is equipped with control components, which include at least the main control board and the operation panel.

[0042] In use, the front ends of the two cables 00 are fixed to the twisted head 100, the two cables 00 are passed through the cable hole 501, and the ends of the two cables 00 are fixed to the cable clamp 430. Traditional structures do not have a movable table component 500 in the stranding machine. During the stranding process, force is applied to the stranding head 100 to rotate. The stranding pitch of the cable closer to the stranding head 100 is smaller, while the stranding pitch of the cable farther away from the stranding head 100 is larger, which leads to the problem of uneven stranding. In this invention, after the movable platform assembly 500 is set up, during use, the first driving device 200 and the second driving device 600 are activated. The first driving device 200 drives the twisting head 100 to rotate, twisting the two cables 00. The second driving device 600 drives the movable platform assembly 500 to move towards the wire clamp assembly 400 to adjust the twist pitch. Specifically, during the twisting process, the part of the cable being twisted is located between the twisting head 100 and the movable platform assembly 500. As the twisting head 100 rotates, the movable platform assembly 500 moves backward continuously. For example, when the twisting head 100 rotates one revolution, the movable platform assembly 500 moves one displacement towards the wire clamp assembly 400. When the twisting head 100 rotates another revolution, the movable platform assembly 500 moves another displacement towards the wire clamp assembly 400, thereby achieving the purpose of controlling the twist pitch. Furthermore, during the twisting process, under the reaction force of the cable 00, the clamp assembly 400 moves toward the twisting head 100; Finally, after the twisting is complete, remove the cable and the user can slowly reset the wire clamp assembly 400 by applying force.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0044] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art.
