The cable arc support portion 32 is provided with an arc-shaped trough body, and the cable arc support portion 32 is used to support and pull the cable 9.
[0028] By setting the circular arc groove on the cable arc support part 32 to uniformly support multiple cable cross-section circles through upper and lower clamping, traction of the cable is achieved during the forward movement of the circulating support plate 11. The circular arc groove can fit the cable body, playing a shaping role and preventing extrusion deformation.
[0029] A plurality of traction rollers 19 are provided in the above-mentioned upper traction device 17 and lower traction device 18. The traction rollers 19 are driven by a transmission belt 20. One traction roller 19 on each of the upper traction device 17 and lower traction device 18 is driven by a motor, and the cable support tooling 3 is located on the transmission belt 20.
[0030] A pressure sensor 33 is provided in the above-mentioned cable arc support part 32. The pressure sensor 33 is connected to a wireless communication device 34, and the wireless communication device 34 transmits the traction pressure value to the controller.
[0031] The traction pressure is detected by the pressure sensor 33, and then it is convenient to control the upper and lower positions of the upper traction device 17 and the lower traction device 18 to adjust the traction pressure.
[0032] The above-mentioned upper traction device 17 and lower traction device 18 are an upper circulating track 1 and a lower circulating track 2. Between the upper circulating track 1 and the lower circulating track 2 are two parallel straight tracks 104. At both ends of the upper circulating track 1 and the lower circulating track 2 are circular arc tracks 103 connecting the two parallel straight tracks 104. The circular arc tracks 103 are inclined with respect to the straight tracks 104 in the horizontal direction. A cable support tooling 3 that circulates is provided in the upper circulating track 1 and the lower circulating track 2. The cable support tooling 3 is provided with a tooling for supporting the cable cross-section arc. The cable support tooling 3 is driven by a drive system 4 to circulate in the upper circulating track 1 and the lower circulating track 2. One of the straight tracks 104 in the upper circulating track 1 and the lower circulating track 2 is opposite up and down, so that the cable support tooling 3 supports and traction the cable 9 being manufactured from above and from below respectively.
[0033] Due to the design that the circular arc track 103 is inclined with respect to the straight track 104 in the horizontal direction, along the cable traction direction, at the inlet, the upper and lower cable support toolings 3 are gradually tightened to achieve clamping and traction of the cable, and at the outlet, the upper and lower cable support toolings 3 are gradually loosened to achieve forward feeding of the cable traction, and the cable cross-section circle is fully supported by the cable support tooling 3, and there will be no situation of local stress.
[0034] The structures of the above-mentioned upper circulating track 1 and lower circulating track 2 are as follows:
[0035] It includes equally spaced outer tracks 101 and inner tracks 102. Between the outer tracks 101 and the inner tracks 102 are two parallel straight tracks 104, and at both ends are circular arc tracks 103 connecting the two parallel straight tracks 104;
[0036] A plurality of loop support plates 11 connected end to end are embedded between the outer track 101 and the inner track 102. The cable support tooling 3 is placed on the loop support plates 11, and the drive system 4 drives the loop support plates 11 to move in a loop between the outer track 101 and the inner track 102, thereby driving the cable support tooling 3 to move in a loop.
[0037] On the other side of the cable support tooling 3, the above-mentioned loop support plates 11 are provided with toggle cylinders 5, and the drive system 4 drives the toggle cylinders 5 to realize the loop movement of the loop support plates 11 and the cable support tooling 3.
[0038] The above-mentioned drive system 4 includes a toggle gear 6 arranged at the circular arc track 103 on one side. The toggle cylinder 5 on the loop support plate 11 at the circular arc track 103 is embedded in the toggle gear 6, and the toggle gear 6 is driven by a drive motor 8 to drive the drive gear set 7 to rotate.
[0039] The toggle gear 6 drives the toggle cylinder 5 to rotate at the circular arc track 103. The toggle cylinder 5 on one side enters the tooth groove of the toggle gear 6, and the toggle cylinder 5 on the other side leaves the tooth groove of the toggle gear 6. The toggle cylinder 5 drives the loop support plate 11 to move in a loop along the track formed by the outer track 101 and the inner track 102.
[0040] The above-mentioned upper loop track 1 and lower loop track 2 share a drive motor 8, and the drive motor 8 drives the upper and lower drive gear sets 7 through a synchronously connected shaft 10 that penetrates up and down.
[0041] By driving the upper and lower two drive gear sets 7 with the same drive motor 8, in addition to saving the number of motors, the upper and lower two gear sets can be synchronized through a mechanical device, and as long as the upper and lower cable support toolings 3 are aligned, the upper and lower can simultaneously clamp the cable 9.
[0042] The above-mentioned loop support plate 11 includes a support plate body 111. The front and rear ends of the support plate body 111 are respectively a concave arc 112 and a convex arc 113 that match each other. Walking wheels 114 are provided on both the front and rear sides of the support plate body 111. The walking wheels 114 are embedded in the outer track 101 and the inner track 102. Lateral rollers 115 are provided on the outer side of the shaft body of the walking wheels 114. The two loop support plates 11 are connected by a plate connection system 12.
[0043] The above-mentioned plate connection system 12 includes a first connection body 121 and a second connection body 122. The first connection body 121 and the second connection body 122 are hinged. The ends of the first connection body 121 and the second connection body 122 are rotatably connected to the connection rings 15 on the circulating support plate 11. The toggle cylinder support plate 16 supports and positions the ends of the first connection body 121 and the second connection body 122. The toggle cylinder 5 is fixedly connected to the toggle cylinder support plate 16.

Through the rotation at both ends and the inner concave arc 112 and the outer convex arc 113 of the front and rear plate bodies, the front and rear plate bodies can perform circular arc motion along the arc-shaped track 103, that is, the two circulating support plates 11 before and after can present an angle up and down, and can also form an arc on the horizontal plane.
