Description
Technical Field
[0001] This utility model belongs to the field of cable protection pipe production technology, and in particular relates to an auxiliary cutting device for cable protection pipe production. Background Technology
[0002] Cable protection pipes are a type of conduit material used to protect cables from external environmental influences and mechanical damage. They are widely used in power, communication, transportation, and municipal fields. The production of cable protection pipes involves various materials, processes, and equipment. Its core lies in producing pipes with corrosion resistance, high strength, and insulation properties through scientific formula design, precision processing, and strict quality control, based on the needs of different application scenarios. The production of cable protection pipes typically includes raw material preparation, mixing and plasticizing, extrusion molding, cooling and shaping, cutting, and packaging. In the production of cable protection pipes, the cutting device is the core equipment to ensure product dimensional accuracy, production efficiency, and adaptability to subsequent applications. During cutting, the cut surface must be flat and burr-free to avoid damaging the cable sheath or affecting subsequent construction.
[0003] The problem with the existing technology is that the unclamped pipe is prone to axial or radial displacement during the cutting process, which causes the cut length to be inconsistent with the design value. Furthermore, the shaking of the pipe will cause the cutting blade to be non-perpendicular to the pipe axis, resulting in a tilted cut. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides an auxiliary cutting device for the production of cable protection pipes. It has the advantage of clamping the pipe, which solves the problem that unclamped pipes are prone to axial or radial displacement during the cutting process, resulting in the cut length not matching the design value. Furthermore, the shaking of the pipe can cause the cutting blade to be non-perpendicular to the pipe axis, resulting in a tilted cut.
[0005] This utility model is implemented as follows: an auxiliary cutting device for the production of cable protection pipes includes a bracket and a cutting machine. The cutting machine is fixedly connected to the middle of the top of the bracket. Movable holes are provided on both the left and right sides of the top of the bracket. A clamping structure is provided inside the movable holes. A transmission hole is provided on the top of the bracket and behind the movable holes.

The connecting gear is rotatably connected to the inside of the transmission hole, and the front side of the connecting gear is fixedly connected to the rear side of the double-ended lead screw. The connecting gear works in conjunction with the transmission structure. By setting the clamping structure, the cable protection tube placed on the cutting machine can be clamped, thereby preventing the cable protection tube from moving during cutting.

[0008] As a preferred embodiment of this utility model, the bottoms of both clamping plates extend through and out of the bottom of the bracket. Placement plates are fixedly connected to the bottom of the bracket and on both sides of the moving hole. The placement plates are flush with the bottom of the extended clamping plates. By setting the placement plates, the force points of the light rod can be provided through the placement plates, and then the movement of the clamping plates can be restricted through the light rod.
[0009] As a preferred embodiment of this utility model, a light rod is fixedly connected to one side of the two placement plates that are close to each other. The light rod passes through the surface of the two clamping plates, and the clamping plates are slidably connected to the surface of the light rod. By setting the light rod, the movement of the clamping plates can be restricted, and the clamping plates can be prevented from tilting when moving.
[0010] As a preferred embodiment of this utility model, the surface of the front clamping plate is provided with a sliding hole, and a clamping component is slidably connected inside the sliding hole. By setting the sliding hole and the clamping component, the clamping component can be flexibly adjusted along the sliding hole according to the size of the cable protection pipe, so as to clamp the cable protection pipe by the clamping component.
[0011] In a preferred embodiment of this invention, the clamping assembly includes a clamping member, a circular plate, and a spacer. The clamping member is slidably connected to the inside of the sliding hole and extends through and out of the surface of the clamping plate. The circular plate is threadedly connected to the surface of the clamping member and fits against the front side of the clamping plate. The spacer is sleeved on the surface of the clamping member and contacts the surface of the circular plate.

The connecting gear 403 is used in conjunction with the transmission structure 7.
[0024] The above solution is adopted: by setting the clamping structure 4, the cable protection pipe placed on the cutting machine 2 can be clamped, thereby preventing the cable protection pipe from moving during cutting.
[0025] refer to Figure 4 The transmission structure 7 includes a motor 701, a drive gear 702, and a placement rack 703.

The drive gear 702 is rotatably connected to the surface of the placement rack 703.
[0026] The above solution is adopted: by setting up the transmission structure 7, the clamping structure 4 can be moved, and then the cable protection pipe is clamped by the clamping structure 4.
[0027] refer to Figure 4 The bottom of both clamping plates 402 extends through and out of the bottom of the bracket 1. The bottom of the bracket 1 and the front and rear sides of the moving hole 3 are fixedly connected to the placement plate 8, and the placement plate 8 is flush with the bottom of the extended clamping plate 402.
[0028] The above solution is adopted: by setting up the placement plate 8, the force point of the light rod 9 can be provided by the placement plate 8, and then the movement of the clamping plate 402 can be restricted by the light rod 9.

[0035] The working principle of this utility model:
[0036] When in use, start the motor 701, which drives the double-ended lead screw 401 to rotate. When the double-ended lead screw 401 rotates, it drives the two threaded clamping plates 402 to move. When the clamping plates 402 move, they move along the surface of the guide rod 9 and clamp the cable protection tube placed on the cutting machine 2. Then, the position of the clamping member 1101 can be adjusted according to the size of the cable protection tube. Then, the cable protection sleeve is clamped by the clamping member 1101 to prevent the cable protection sleeve from moving during cutting.
