[0004] In the above technology, the cable to be cut is placed between two corresponding crimping rollers on multiple rotating rods on the support frame, and the corresponding crimping rollers clamp the cable and transmit the cable. The second motor is operated to drive the pulley in the cavity to operate, and the other pulley is operated under the drive of the belt. Under the drive of the gear, all the rotating rods are operated and drive the crimping rollers to transmit the cable. However, when the crimping roller rotates, it will drive the cable to move. Therefore, the position of the cable may be offset during the movement, and it may not be able to move accurately to the bottom of the cutting knife when cutting, which will cause errors in cutting.

[0005] In view of this, the utility model solves the above technical problems by proposing a cable production cutting machine. Utility Model Content

[0012] As a preferred technical solution of the present invention, two mounting brackets are fixed on the top of the workbench, two crimping rollers are rotatably mounted between the mounting brackets, and a driving device is fixed on one side of the mounting brackets.

[0013] As a preferred technical solution of the present invention, two limiting holes are provided on the top of the support plate, limiting columns are slidably installed inside the limiting holes, and the bottom ends of the limiting columns are fixedly connected to the top of the cutting knife.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, the cable is conveyed to the placement groove by the rotation of the wire-pressing roller, and then the positioning arc plate is driven downward by the telescopic end of the electric push rod to press and position the cable, thereby avoiding displacement of the cable during cutting. Before this, the output end of the servo motor is rotated to drive the bidirectional screw rod to rotate, thereby driving the moving block to move, thereby making the blocking arc plates approach each other, so that the cable conveyed by the wire-pressing roller can be blocked and limited, avoiding the cable from being skewed before entering the cut-off, thereby improving the accuracy of the cut-off, reducing the risk of errors, and protecting the surface of the cable by the anti-deflection arc plate and the protective pad to avoid wear and tear that affects the safety of subsequent cables.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:

[0023] See also Figure 1-4 As shown, a cable production cutting machine includes: a workbench 1, a support plate 2 is fixed on the top of the workbench 1, a hydraulic rod 3 is fixed on the top of the support plate 2, the telescopic end of the hydraulic rod 3 passes through the support plate 2, and a cutting knife 4 is fixed on the telescopic end of the hydraulic rod 3;

[0024] A support base 5 is fixed on the top of the workbench 1, a positioning block 6 is fixed on the top of the support base 5, a servo motor 7 is fixed inside the support base 5, a bidirectional screw rod 8 is fixed to the output end of the servo motor 7, the outer wall of the bidirectional screw rod 8 is threadedly connected to two moving blocks 9, a support column 10 is fixed on the top of the moving block 9, a blocking arc plate 11 is fixed on the top of the support column 10, an anti-deflection arc plate 12 is slidably installed inside the blocking arc plate 11, two placement grooves 13 are respectively provided on both sides of the positioning block 6, and a truncation groove 14 is provided on the top of the positioning block 6.

[0025] During use, the hydraulic rod 3 can be supported by the support plate 2, and then the hydraulic rod 3 pushes the cutting knife 4 to move downward, so that the cable can be cut. During cutting, the cutting groove 14 can provide a buffer space for the cutting knife 4, thereby avoiding damage to the cutting knife 4. Before cutting, the output end of the servo motor 7 rotates, driving the bidirectional screw rod 8 to rotate, thereby driving the moving block 9 to move, thereby making the blocking arc plates 11 approach each other. At this time, the anti-deflection arc plate 12 is in contact with the surface of the cable, so it can ensure that the cable is always between the blocking arc plates 11, avoiding the position deviation of the cable during the movement, thereby improving the accuracy of cutting and reducing the risk of errors.

[0026] Example 2:

[0027] As a specific embodiment of the present invention, please refer to Figure 1-4 As shown, two support frames 15 are fixed on the top of the positioning block 6, and an electric push rod 16 is fixed on the top of the support frame 15. The telescopic end of the electric push rod 16 passes through the support frame 15, and the telescopic end of the electric push rod 16 is fixed with a positioning arc plate 17. Two springs 18 are fixed to the inner wall of the blocking arc plate 11, and the other end of the spring 18 is fixedly connected to the outer wall of the anti-deflection arc plate 12. A limiting rod 19 is slidably installed inside the spring 18, and one end of the limiting rod 19 passes through the blocking arc plate 11. Protective pads 20 are respectively fixed to the inside of the placement groove 13 and the truncation groove 14. Two mounting brackets 21 are fixed on the top of the workbench 1, and two pressing rollers 22 are rotatably installed between the mounting brackets 21. A driving device 23 is fixed on one side of the mounting bracket 21. The driving device 23 includes a driving motor, a gear, and a toothed belt. The output shaft of the driving motor is fixedly connected to one end of a pressing roller 22, and the gear is fixedly installed on the pressing roller 22. The gear is meshed with the toothed belt. Two limiting holes 24 are provided on the top of the support plate 2. A limiting column 25 is slidably installed inside the limiting hole 24, and the bottom end of the limiting column 25 is fixedly connected to the top of the cutting knife 4.

[0028] During use, the telescopic end of the electric push rod 16 is extended and retracted to drive the positioning arc plate 17 to move downward, thereby pressing the cable to position, avoiding displacement of the cable when cutting. When blocking the cable, the anti-deflection arc plate 12 squeezes the spring 18, thereby avoiding excessive squeezing force and causing damage to the cable. At the same time, the spring 18 can be limited by the limit rod 19 to avoid the spring 18 from tilting and causing poor blocking effect. When cutting, the protective pad 20 can protect the surface of the cable, reduce wear and improve safety. The wire pressing roller 22 is supported by the mounting bracket 21, and then the wire pressing roller 22 is rotated by the driving device 23, so that the cable can be transported. The limiting hole 24 and the limiting column 25 can make the cutting knife 4 more stable when cutting, reducing the shaking, thereby avoiding unevenness at the cut end of the cable after cutting and affecting normal use.
