[0023] The staff first passes the cable through the threading holes 106 on both sides of the processing box 1, and then starts a plurality of stepper motors 401 after the cable is pulled out to a certain length. When the output end of the stepper motor 401 rotates, it can drive the first positioning arc plate 402 and the second positioning arc plate 403 to move toward each other. After the stepper motor 401 has been operating for a period of time, the first positioning arc plate 402 and the second positioning arc plate 403 can lock the cable. At this time, the stepper motor 401 is turned off, and then the staff manually or by using a clamp fixes one end of the cable to be cut, and starts the second cylinder 404. After the second cylinder 404 is operated, the cable is tightened through the first positioning arc plate 402 and the second positioning arc plate 403, so as to reduce the probability of bending of the cable when being cut and improve the cable cutting effect;

[0024] When the cable is tightened, the staff starts the first cylinder 301 and the forward and reverse motor 303. After the first cylinder 301 is in operation, it pushes the forward and reverse motor 303 and the cutter 304 to move, so that the plurality of cutters 304 can cut the cable. By cutting and processing a plurality of cables at the same time, the work efficiency is effectively improved. At the same time, when the output end of the forward and reverse motor 303 rotates, the cutter 304 is driven to rotate, so that the cutter 304 can continuously reciprocate when cutting the cable, and then cut the cable at different angles, effectively improving the cutting effect and further improving the work efficiency.

[0025] The stepper motor 401 and the forward and reverse motor 303 are both prior art and will not be explained here.

[0026] In one embodiment, the cutting mechanism 3 also includes a fixed plate 302, a rotating shaft 305, a hollow plate 306 and a support frame 307, the support frame 307 is fixedly connected to the top of the processing box 1, the first cylinder 301 is fixedly installed at the bottom of the support frame 307, and the output end is fixedly connected to the fixed plate 302, the fixed plate 302 is fixedly connected to the two hollow plates 306, the forward and reverse motor 303 is fixedly installed at one end of the hollow plate 306, and the output end is fixedly connected to one end of the rotating shaft 305, the other end of the rotating shaft 305 is rotatably connected to the inner wall of the hollow plate 306, and the cutter 304 is fixedly sleeved on the rotating shaft 305 and arranged in the hollow plate 306.

[0027] After the first cylinder 301 is operated, the two cutters 304 are driven to move vertically downward through the fixed plate 302 and the two hollow plates 306, thereby achieving the effect of cutting multiple cables at the same time, thereby improving work efficiency.

[0028] In one embodiment, the positioning mechanism 4 further includes a bidirectional screw 405, a slide rail 406, a connecting rod 407, a mounting plate 408, a welding plate 409, a mounting seat 410 and a protective baffle 412. The welding plate 409 is fixedly connected to the inner wall of the processing box 1, the slide rail 406 is fixedly installed at one end of the mounting plate 408, and the top is fixedly connected to the mounting seat 410, the protective baffle 412 is fixedly connected to the top of the mounting seat 410, and the mounting end of the stepper motor 401 is fixedly connected to the protective baffle 412. 2 is fixedly connected, and the output end is fixedly connected to the bidirectional screw 405, the bidirectional screw 405 passes through the slide rail 406, and the other end is rotatably connected to the slide rail 406, two connecting rods 407 are both threadedly sleeved on the bidirectional screw 405, and slideably cooperate with the slide rail 406, the first positioning arc plate 402 and the second positioning arc plate 403 are fixedly connected to the two connecting rods 407 respectively, the second cylinder 404 is fixedly mounted on one end of the welding plate 409, and the output end is fixedly connected to the mounting plate 408.

[0029] The welding plate 409 is used to support the entire positioning mechanism 4, so that the positioning mechanism 4 can be firmly fixed inside the processing box 1. At the same time, through the mutual cooperation between the bidirectional screw 405, the slide rail 406 and the connecting rod 407, the output end of the stepper motor 401 can drive the first positioning arc plate 402 and the second positioning arc plate 403 to move toward or away from each other when it rotates, thereby achieving the effect of locking and unlocking the cable and improving applicability.

[0030] In one embodiment, a plurality of gaskets 5 are fixedly installed on both sides of the processing box 1, and a controller 103 is fixedly installed on one side. A support base 2 is fixedly installed on the bottom of the processing box 1, and a slot 104 is opened on the top. An external base 102 is fixedly installed on one end of the support base 2.

[0031] The gasket 5 can play a certain guiding role, so that the cable can pass through the threading hole 106, which is convenient for the staff to operate and further improves the applicability.

[0032] In one embodiment, a plurality of legs 101 are fixedly mounted on the bottom of the support base 2 .

[0033] Several legs 101 are used to increase the overall height of the device, further improving its applicability.

[0034] The following is a detailed description of the working principle of the wire and cable shearing device:

[0035] The staff first passes the cable through the threading holes 106 on both sides of the processing box 1, and then starts a number of stepper motors 401 after the cable is pulled out to a certain length. When the output end of the stepper motor 401 rotates, it first drives the bidirectional screw 405 to rotate. When the bidirectional screw 405 rotates, it is threadedly matched with the two connecting rods 407. Since the two connecting rods 407 are limited by the slide rail 406, they can slide in the slide rail 406 at this time. At this time, the two connecting rods 407 can drive the first positioning arc plate 402 and the second positioning arc plate 403 move towards each other, and the stepper motor 401 is turned off after the bidirectional screw 405 rotates a certain number of times. At this time, the first positioning arc plate 402 and the second positioning arc plate 403 can lock the cable line, and then the staff manually or uses a clamp to fix the end of the cable line to be cut, and start the second cylinder 404. After the second cylinder 404 is operated, the cable line is tightened through the first positioning arc plate 402 and the second positioning arc plate 403, reducing the probability of the cable line bending when being cut, and improving the cable cutting effect;

[0036] When the cable is tightened, the staff starts the first cylinder 301 and the forward and reverse motor 303. After the first cylinder 301 is operated, it pushes the fixed plate 302 to move vertically downward. When the fixed plate 302 moves, it drives the two hollow plates 306 to move. When the hollow plate 306 moves, it drives the forward and reverse motors 303, the rotating shaft 305 and the cutter 304 to move, so that several cutters 304 can cut the cable. By cutting and processing several cables at the same time, the work efficiency is effectively improved. At the same time, when the output end of the forward and reverse motor 303 rotates, it drives the rotating shaft 305 to rotate. After the rotating shaft 305 rotates, it drives the cutter 304 to rotate, so that the cutter 304 can continuously rotate back and forth when cutting the cable, and then cut the cable at different angles, effectively improving the cutting effect and further improving the work efficiency.

[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
