Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable processing, and particularly relates to a cable cutting device. Background Technique
[0002] When producing cables and recycling waste cables, it is necessary to cut the cables to meet the fixed-length requirements and facilitate the stripping of the insulating layer.
[0003] When cutting a cable, it is necessary to clamp and position the cable to avoid the cable moving during the cutting process, resulting in force unloading and deviation of the cutting position, thereby increasing the energy consumption, reducing the efficiency and making the cable fracture uneven during cable cutting.
[0004] In the existing cable cutting device, the cable clamping mechanism and the cable cutting mechanism usually need to be powered by different power sources respectively, and the hardware cost is relatively high. Moreover, when the cable cutting device is semi-automatic or manually driven, the clamping and cutting of the cable need to be operated manually successively, which is inconvenient to operate and has low efficiency. Content of the Utility Model
[0005] The purpose of the utility model is to provide a cable cutting device to solve the above technical problems.
[0006] Based on the above purpose, the utility model provides a cable cutting device, which includes a processing platform and a guillotine. A fixed clamp is arranged on the side of the processing platform. An active clamp and a swing arm are arranged on the processing platform. One end of the swing arm is hinged to the processing platform. One end of the guillotine is rotatably arranged at the end of the fixed clamp.
[0007] The active clamp is slidably arranged on the processing platform. The swing arm is connected to the active clamp through a direction-changing transmission component, so that the active clamp approaches and moves away from the fixed clamp as the swing arm swings back and forth.
[0008] The other end of the guillotine is connected to the swing arm through a linkage rod, and both the guillotine and the swing arm are hinged to the linkage rod.
[0009] Further, the direction-changing transmission component includes a linkage shaft and a dummy spring. A chute is arranged at the end of the active clamp close to the swing arm. One end of the linkage shaft is slidably inserted into the chute. The dummy spring is arranged in the chute and connected to the linkage shaft. A sliding sleeve is slidably sleeved on the swing arm along the length direction. The linkage shaft is connected to the sliding sleeve.
[0010] Further, fixed clamps, active clamps and guillotines are arranged on both sides of the processing platform.
[0011] Furthermore, two fixed clamping plates and two movable clamping plates are arranged on both sides of the processing platform. The guillotine is located between the two fixed clamping plates on the same side, and the swing arm is located between the two movable clamping plates on the same side.
[0012] Furthermore, a chip removal groove is arranged at the top of the processing platform. One end of the chip removal groove penetrates through the side wall of the processing platform, and the other end of the chip removal groove extends to the cable cutting position.
[0013] Furthermore, the chip removal groove is inclined, and the lower end of the chip removal groove penetrates through the side wall of the processing platform.
[0014] Advantages of the present utility model:
[0015] In the present utility model, a synchronous drive mechanism is composed of a swing arm, a direction-changing transmission component and a linkage rod. Thus, during the reciprocating swing of the swing arm, the movable clamping plate and the guillotine can approach and move away from the fixed clamping plate synchronously, simplifying the cable cutting operation and being beneficial to improving the cable cutting and processing efficiency.

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Such as Figures 1 to 3As shown in the figure, a cable cutting device includes a processing platform 1 and a guillotine 2. A fixed clamping plate 3 is arranged on the side of the processing platform 1. An active clamping plate 4 and a swing arm 5 are arranged on the processing platform 1. One end of the swing arm 5 is hinged to the processing platform 1. One end of the guillotine 2 is rotatably arranged at the end of the fixed clamping plate 3;
[0025] The active clamping plate 4 is slidably arranged on the processing platform 1. The swing arm 5 is connected to the active clamping plate 4 through a direction-changing transmission component 7, so that the active clamping plate 4 approaches and moves away from the fixed clamping plate 3 as the swing arm 5 swings back and forth;
[0026] The guillotine 2 is connected to the swing arm 5 through a linkage rod 6, and both the guillotine 2 and the swing arm 5 are hinged to the linkage rod 6.
[0027] Specifically, the cable to be cut is passed through between the fixed clamping plate 3 and the active clamping plate 4, and then the swing arm 5 is manually or instrumentally driven to swing towards one side of the cable to be cut. During this process, under the action of the direction-changing transmission component 7, the swing arm 5 drives the active clamping plate 4 to approach the fixed clamping plate 3 until the cable is clamped. At the same time, the swing arm 5 pushes the linkage rod 6 to drive the guillotine 2 to rotate, so that the guillotine 2 cuts the clamped cable.
[0028] Among them, the guillotine 2 is in clearance fit with the end of the fixed clamping plate 3 to reduce the deformation of the cable during the process of being cut by the guillotine 2, that is, the guillotine 2 cooperates with the fixed clamping plate 3 to shear the cable, which is beneficial to cutting the cable and beneficial to the flatness of the cable cut.
[0029] The utility model forms a synchronous drive mechanism through the swing arm 5, the direction-changing transmission component 7 and the linkage rod 6. Thus, during the reciprocating swing of the swing arm 5, the active clamping plate 4 and the guillotine 2 can approach and move away from the fixed clamping plate 3 synchronously, simplifying the cable cutting operation and being beneficial to improving the cable cutting processing efficiency.
[0030] It should be added that a groove for the lower end of the swing arm 5 to move is arranged on the processing platform 1 to facilitate reducing the height of the active clamping plate 4. Although, the setting method that the connection part of the direction-changing transmission component 7 and the active clamping plate 4 is located below the connection part of the swing arm 5 and the processing platform 1 can be adopted, but a support structure for the swing arm 5 needs to be installed on the processing platform 1, which is not convenient for the flexible setting of the active clamping plate 4 and the direction-changing transmission component 7.
[0031] Among them, the direction-changing transmission assembly 7 includes a linkage shaft 701 and a play spring 702. A chute 8 is provided at the end of the movable clamping plate 4 close to the swing arm 5. One end of the linkage shaft 701 is slidably inserted into the chute 8. The play spring 702 is arranged in the chute 8 and connected to the linkage shaft 701. A sliding sleeve 703 is slidably sleeved on the swing arm 5 along the length direction, and the linkage shaft 701 is connected to the sliding sleeve 703. When the swing arm 5 swings back and forth, the sliding sleeve 703 reciprocates in the horizontal direction, and the sliding sleeve 703 maintains a constant horizontal height by sliding relative to the swing arm 5. The linkage shaft 701 and the movable clamping plate 4 are softly connected through the play spring 702, so that after the movable clamping plate 4 clamps the cable, the swing arm 5 can still continue to move by compressing the play spring 702, enabling the cable clamping and shearing to not affect each other.
[0032] In addition, since the angle of the linkage shaft 701 changes as the swing arm 5 swings, therefore, the linkage shaft 701 is preferably of a cylindrical structure. And in order to stably connect the play spring 702 with the linkage shaft 701, a square slider that can slidably cooperate with the chute 8 is rotatably sleeved on the linkage shaft 701.
[0033] What is further optimized on the basis of the above embodiment is that fixed clamping plates 3, movable clamping plates 4 and guillotines 2 are arranged on both sides of the processing platform 1, so as to realize the shearing of the cables on both sides of the processing platform 1 alternately through the reciprocating swing of the swing arm 5.
[0034] What is further optimized on the basis of the above embodiment is that two fixed clamping plates 3 and two movable clamping plates 4 are arranged on both sides of the processing platform 1. The guillotine 2 is located between the two fixed clamping plates 3 on the same side, and the swing arm 5 is located between the two movable clamping plates 4 on the same side. At both ends of the cable shearing position, the cable is clamped by the cooperation of the two movable clamping plates 4 and the fixed clamping plates 3 respectively, which is beneficial to the stability of the cable when it is cut, and thus beneficial to the flatness of the cable cut.
[0035] What is further optimized on the basis of the above embodiment is that a chip removal groove 9 is arranged on the top of the processing platform 1. One end of the chip removal groove 9 penetrates the side wall of the processing platform 1, and the other end of the chip removal groove 9 extends to the cable cutting position. The chips generated by shearing the cable fall into the chip removal groove 9 to facilitate keeping the surface of the processing platform 1 clean. And the chip removal groove 9 is inclined, and the lower end of the chip removal groove 9 penetrates the side wall of the processing platform 1, so that the chips in the chip removal groove 9 can be discharged from the chip removal groove 9 by their own gravity.
[0036] As is known by common technical knowledge, the present utility model can be implemented by other embodiments that do not depart from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and are not exclusive. All changes within the scope of the present utility model or within the scope equivalent to the present utility model are encompassed by the present utility model.
