Description

Technical Field

[0001] The utility model relates to the technical field of cutting for producing CPVC cable protection tubes, and more particularly to a cutting device for producing CPVC cable protection tubes. Background Art

[0002] Under current production technology, while CPVC cable protection tubes possess many excellent properties, such as corrosion resistance, flame retardancy, and insulation, their material is relatively fragile and susceptible to damage, particularly during the cutting process. Existing cutting devices used in the production of CPVC cable protection tubes often utilize a rigid contact method for cutting, which presents certain drawbacks. First, the rigid contact of the cutting device can easily cause excessive pressure on the tube wall of the CPVC cable protection tube. This pressure can not only cause scratches and wear on the tube wall, but can even cause deformation and cracks in the tube, seriously affecting the quality and service life of the tube.

[0003] Secondly, due to the design limitations of existing cutting devices, the rigid-contact cutting method can damage CPVC cable protection tubes not only at the cut site but also along the entire length of the tube. This damage can make the tube more susceptible to external forces during installation and use, reducing its safety performance. Furthermore, damage to the tube wall during cutting can increase risks during cable routing, such as insulation wear and short circuits, posing a threat to the stability and security of the entire power and communications system.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a cutting device for producing CPVC cable protection tubes, which has the following beneficial effects:

The fixing rods 7 at both ends are respectively provided with insertion rods 13, and the multiple insertion rods 13 are respectively sleeved with synchronization sleeves 14. The synchronization sleeve 14 at the bottom is pressed on the base 4. The fixing mechanism includes a positioning rod 15 and a threaded sleeve 16. The positioning rod 15 is installed on the internal rod 5. The threaded sleeve 16 is threaded on the positioning rod 15, and the threaded sleeve 16 is fitted on the top synchronization sleeve 14.

A slide rail 20 is provided on the support frame 1, and the clamping block 19 is slidably connected to the slide rail 20.

[0030] In this embodiment, when the protective tube needs to be fixed, the push block 3 can be driven to slide along the block under the action of the first cylinder 17. Since the protective tube is stuck on the baffle 2, the friction disk 9 on the spring 8 is then made to contact the side wall of the protective tube. Since the insertion rod 13 is stuck on the synchronous sleeve 14, the limit between the spring 8 and the follower sleeve 6 can be guaranteed. Then the internal hole 10 on the follower sleeve 6 is stuck on the internal rod 5, and then the follower sleeve 6 and the internal rod 5 are guaranteed to be in the limit position. Therefore, when the friction disk 9 contacts the side wall of the protective tube, it will deform accordingly with the curvature of the protective tube, and then the corresponding fixing process can be carried out, thereby avoiding damage to the tube wall caused by rigid fixation.

[0033] In summary, when the overall equipment is in use or running: when the protective tube needs to be fixed, the push block 3 can be driven to slide along the block under the action of the first cylinder 17. Since the protective tube is stuck on the baffle 2, the friction disk 9 on the spring 8 is abutted against the side wall of the protective tube. Since the insertion rod 13 is stuck on the synchronous sleeve 14, the limit between the spring 8 and the follower sleeve 6 can be guaranteed. Then the internal hole 10 on the follower sleeve 6 is stuck on the internal rod 5, and then the follower sleeve 6 and the internal rod 5 are guaranteed to be in the limit position. Therefore, when the friction disk 9 abuts against the side wall of the protective tube, it will deform accordingly with the curvature of the protective tube, and then the corresponding fixing process can be carried out, thereby avoiding damage to the tube wall caused by rigid fixation. When cutting is required, the hydraulic cylinder 23 drives the cutting machine 21 to rotate along the support frame 1, and then the cutting blade 22 abuts against the protective tube. Then, the rotation of the cutting machine 21 causes the cutting blade 22 to rotate, thereby completing the cutting process.
