Description

Technical Field

[0001] This utility model relates to the field of pretreatment technology for coated tubes, specifically to a device for cutting and pre-peeling marks on coated tubes. Background Technology

[0002] When welding PE-coated pipe sections, the coating layer near the end face of the pipe needs to be peeled off from the pipe material (e.g., Figure 1 (As shown in the image) Then welding is performed. Improper handling during the peeling of the coating can damage the pipe body and reduce the strength of the pipe; moreover, if too much of the coating is peeled off, the pipe will not provide protection. Therefore, the peeling distance should be as short as possible to protect the PE pipe body to the greatest extent.

[0003] The current method of tightening steel wire ropes involves first marking pre-peeling lines on the coated pipe according to the required peeling width, and then peeling off the coating layer according to these lines. However, due to the error between the cutting length and the marking length, the neatness of the end face cannot be guaranteed. Large errors can also result in scrapped pipes, causing unnecessary waste of pipe materials. Furthermore, steel wire ropes will wear and break over time, increasing the workload of inspections.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] A device for cutting pre-peeling marks on a coated tube includes a support tube 1, the inner diameter of which matches the outer diameter of the coated tube 23. The support tube 1 is horizontally arranged, and a rotating component 2 is sleeved on the support tube 1. The rotating component 2 rotates on the support tube 1. The rotating component 2 is provided with a tube cutting assembly and a cutting assembly. The tube cutting assembly is used to cut the coated tube 23, and the cutting assembly is used to cut pre-peeling marks at the cut section of the coated tube 23.

[0022] The pipe cutting assembly includes a propulsion mechanism mounted on the rotating component 2 and moving along the length of the support pipe 1. The propulsion mechanism is provided with a rotating pipe cutting disc 15 via a distance adjustment mechanism. The adjustment direction of the distance adjustment mechanism is perpendicular to the pipe wall of the support pipe 1. The pipe cutting disc 15 extends out of the end face of the support pipe 1.

[0023] The shaving assembly includes a distance adjustment mechanism 2 disposed on the rotating component 2. The distance adjustment mechanism 2 is provided with a rotating shaving blade 21. The adjustment direction of the distance adjustment mechanism 2 is perpendicular to the wall of the support tube 1. The shaving blade 21 extends out of the end face of the support tube 1. The shaving blade 21 and the tube cutting blade 15 are located at the same end of the support tube 1.

[0024] The coating tube 23 passes through one end of the support tube 1. The cutting disc 15 is moved to a suitable cutting position by the pushing mechanism. The distance adjustment mechanism 1 drives the cutting disc 15 deeper into the coating tube 23 for cutting, while the distance adjustment mechanism 2 drives the slicing disc 21 deeper into the outer wall of the coating tube 23 to cut pre-peeling marks. The rotation of the rotating component 2 causes the cutting disc 15 and the slicing disc 21 to rotate around the coating tube 23 once, thus cutting the coating tube 23 and simultaneously cutting a ring of pre-peeling marks on the outer wall of the coating tube. After the rotating component 2 rotates once and completes the cutting, it rotates in the opposite direction to reset, preventing the rotating component 2 from rotating only in one direction and causing the wire harness to become entangled.

[0025] The depth to which the cutting disc 21 penetrates into the outer wall of the covering tube 23 can be adjusted by the distance adjustment mechanism 2, thereby controlling the peeling thickness; and the distance between the cutting disc 15 and the cutting disc 21 can be adjusted by moving the tube cutting disc 15 by the pushing mechanism, thereby controlling the peeling width.

[0026] In a preferred embodiment, a synchronous pulley 3 is fixedly connected to the rotating component 2, a motor 6 is provided on one side of the support tube 1, and a synchronous pulley 4 is fixedly provided at the output end of the motor 6. The synchronous pulley 3 and the synchronous pulley 4 are connected by a synchronous belt 5.

[0027] Motor 6 drives the rotating component 2 to rotate on the support tube 1 via synchronous pulley 4, synchronous belt 5 and synchronous pulley 3.

[0028] In a preferred embodiment, the propulsion mechanism includes a slide rail 7 fixedly mounted on the rotating component 2. The length direction of the slide rail 7 is parallel to the length direction of the support tube 1. A sliding seat 8 is slidably mounted on the slide rail 7. The sliding seat 8 is driven to slide by a cylinder 9 mounted on the rotating component 2. The distance adjustment mechanism is mounted on the sliding seat 8.

[0029] Cylinder 9 drives slide 8 to move on slide rail 7, thereby moving the pipe cutting disc 15 in the horizontal direction and adjusting the position of the pipe cutting disc 15.

[0030] In a preferred embodiment, the distance adjustment mechanism includes a support 10, on which a sliding slider 11 is mounted. The sliding direction of the slider 11 is perpendicular to the wall of the support tube 1. The slider 11 is driven to slide by a cylinder 14 mounted on the support 10. The tube cutting disc 15 is rotatably mounted on the slider 11 and driven to rotate by a motor 12. A guide rod 13 is fixedly mounted on the support 10. The length direction of the guide rod 13 is parallel to the sliding direction of the slider 11. The slider 11 has a guide hole that matches the guide rod 13, and the slider 11 slides on the guide rod 13 through the guide hole.

[0031] Driven by cylinder 14, slider 11 moves along a direction perpendicular to the wall of support tube 1.

[0032] In a preferred embodiment, the distance adjustment mechanism includes a support 16, on which a sliding slider 17 is mounted. The sliding direction of the slider 17 is perpendicular to the wall of the support tube 1. The slider 17 is driven to slide by a cylinder 19 mounted on the support 16. The tube cutting disc 15 is rotatably mounted on the slider 17 and driven to rotate by a motor 18. A guide rod 20 is fixedly mounted on the support 16. The length direction of the guide rod 20 is parallel to the sliding direction of the slider 17. The slider 17 has a guide hole 2 that matches the guide rod 20, and the slider 17 slides on the guide rod 20 through the guide hole 2.

[0033] Driven by cylinder 319, slider 217 moves along a direction perpendicular to the wall of support tube 1, thereby adjusting the depth of the cut.

[0034] In a preferred embodiment, the support tube 1 has multiple protruding limiting edges 22 on its tube wall, and the inner wall of the rotating component 2 has limiting grooves that are adapted to the limiting edges 22 one by one.
