[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides a cable cutting machine, including a base plate 1. A reciprocating mechanism 2 and a cutting mechanism 3 are fixedly mounted on the upper surface of the base plate 1. The reciprocating mechanism 2 includes two support frames 20, which are symmetrically fixed on the upper surface of the base plate 1. A motor 23 is fixedly mounted on one side of the support frame 20. An eccentric circular frame 24 is fixedly mounted on the output end of the motor 23. A lifting rod 25 is mounted on one side of the eccentric circular frame 24. The upper end of the lifting rod 25 passes through the upper surface of the support frame 20. Two horizontally distributed lifting wheels 21 are rotatably mounted on one side of the lifting rod 25. The outer surfaces of the two lifting wheels 21 slide against the inner and outer surfaces of the eccentric circular frame 24, respectively. A lifting plate 28 is fixedly mounted on one side of the two lifting rods 25. Two symmetrically distributed limiting rods 26 are fixedly mounted on the upper surface of the lifting plate 28. The upper ends of the limiting rods 26 pass through the upper surface of the support frame 20. A limiting spring 27 is sleeved on the outer side of the limiting rods 26. When the reciprocating mechanism 2 is in use, the motor 23 starts and drives the eccentric circular frame 24 to rotate. Because the lifting wheel 21 slides and engages with the inner and outer surfaces of the eccentric frame 24, the lifting wheel 21 moves along the trajectory of the eccentric frame 24, thereby driving the lifting rod 25 to move up and down. The upper end of the lifting rod 25 penetrates the upper surface of the support frame 20, and its movement is directly transmitted to the lifting plate 28. The limiting rod 26 on the upper surface of the lifting plate 28 moves up and down accordingly, and the limiting spring 27 on the outer side of the limiting rod 26 plays a buffering and limiting role, ensuring the smoothness and accuracy of the movement of the lifting plate 28. In this way, the reciprocating mechanism 2 realizes the reciprocating motion of the lifting plate 28, providing a stable power source for the cutting mechanism 3.

[0024] Specifically, the cutting mechanism 3 includes two reset rods 30, which are symmetrically distributed on the upper surface of the bottom plate 1. The outer side of the reset rod 30 is sleeved with a reset spring 37, and the outer side of the reset rod 30 is slidably provided with a reset plate 33. One side of the two reset plates 33 is fixedly provided with a push plate 32, the upper surface of the push plate 32 is in close contact with the lower surface of the lifting plate 28, and one side of the push plate 32 is fixedly provided with an upper cutter 34. One side of the bottom plate 1 is fixedly provided with a lower cutter 35. When the lifting plate 28 of the reciprocating mechanism 2 moves downward, the lower surface of the lifting plate 28 is in close contact with the upper surface of the push plate 32, and the push plate 32 is pushed to move downward. The reset plates 33 on both sides of the push plate 32 slide on the reset rods 30, and at the same time, the reset springs 37 are compressed. The upper cutter 34 on one side of the push plate 32 moves downward, cooperates with the lower cutter 35 on one side of the bottom plate 1, and cuts the cable. After cutting, the lifting plate 28 moves upward, the reset spring 37 releases energy, and the push plate 32 and the push plate 32 move upward. The upper cutter 34 is reset, ready for the next cutting.

[0025] Further, the two baffles 4 on the upper surface of the bottom plate 1 are fixedly matched with the support frame 20, effectively preventing the cable from bouncing out after cutting, and improving the safety of cutting.

[0026] Further, the plurality of cable grooves 5 on the upper surface of the bottom plate 1 are linearly distributed, which facilitates the neat arrangement and positioning of the cable, improves the cutting efficiency, and reduces the wear and damage of the cable.

[0027] It is worth noting that the mounting bracket 22 on one side of the support frame 20 is fixedly matched with the motor 23, which provides a stable mounting position for the motor 23, ensures the stable operation of the motor 23, and reduces the cutting error caused by the vibration of the motor 23.

[0028] It is worth noting that the reset hole 31 on the upper surface of the reset plate 33 is in sliding contact with the reset rod 30, which ensures smooth sliding of the reset plate 33 on the reset rod 30, improves the reset accuracy and speed, and further improves the cutting efficiency.

[0029] It is worth mentioning that the cutter groove 36 on one side of the bottom plate 1 is in sliding contact with the upper cutter 34, which provides a stable movement track for the upper cutter 34, ensures the stability and accuracy of the upper cutter 34 during cutting.

[0030] It is worth emphasizing that one side of the upper cutter 34 is in sliding contact with one side of the lower cutter 35, which ensures the close cooperation of the upper cutter 34 and the lower cutter 35 during cutting, improves the flatness and accuracy of cutting, and reduces the burr and deformation of the cable.

[0031] Wherein, motor 23 is prior art, do not repeat; Meanwhile, the utility model still includes power, controller and switch etc., it is not the main technical point of this patent, do not repeat;The " front, rear, left, right " visual angle of this device is with the direction of drawing as reference. Figure 1 The direction of drawing is the reference.

[0032] Working principle: reciprocating mechanism 2 when using, motor 23 starts, drives eccentric round frame 24 rotation. Because lifting wheel 21 and the inner and outer surface of eccentric round frame 24 slide fit, lifting wheel 21 will move along the track of eccentric round frame 24, in turn drive lifting rod 25 up and down. The upper end of lifting rod 25 penetrates the upper surface of support frame 20, and its movement is directly transmitted to lifting plate 28. The limiting rod 26 on the upper surface of lifting plate 28 moves up and down, and the limiting spring 27 on the outer side of the limiting rod 26 plays a buffering and limiting role, ensuring the stability and accuracy of the movement of the lifting plate 28. In this way, the reciprocating mechanism 2 realizes the reciprocating motion of the lifting plate 28, providing a stable power source for the cutting mechanism 3;

[0033] When the cutting mechanism 3 is used, when the lifting plate 28 of the reciprocating mechanism 2 moves downward, its lower surface is in close contact with the upper surface of the push plate 32, which drives the push plate 32 to move downward. The reset plate 33 on both sides of the push plate 32 slides on the reset rod 30, while the reset spring 37 is compressed. The upper cutter 34 on one side of the push plate 32 moves downward, cooperating with the lower cutter 35 on one side of the bottom plate 1 to cut the cable. After cutting, the lifting plate 28 moves upward, the reset spring 37 releases energy, driving the reset plate 33 and the push plate 32 to move upward, and the upper cutter 34 resets, preparing for the next cutting.
