Description

Technical Field

[0001] The utility model relates to the technical field of pipeline production equipment, in particular to a cutting device for the incision of a traction pipe used for pipeline extrusion bonding and traction. Background Art

[0002] When plastic pipelines are extruded and produced, first, the traction pipe prepared on the vacuum box is adjusted to a suitable position for waiting for traction. The new pipe material extruded by the extruder is adhered to the traction pipe and connected. The new pipe material is pulled into the vacuum box by the traction pipe for shaping and then enters the cold water tank for cooling, and finally, the finished product comes out. In order to better connect the traction pipe with the new pipe material and prevent it from loosening, generally, the operator will cut the end of the traction pipe into a horseshoe-shaped bevel to increase the connection area of the pipe material, facilitate the adhesion of the new pipe material, and prevent it from falling off easily during the traction process.

[0003] However, in the prior art, the shearing of the traction pipe is manual shearing. Manual shearing is relatively convenient for small-sized pipes, but when producing large-sized pipes, manual shearing not only has too high an operation difficulty but also is time-consuming and laborious. Therefore, a simple and convenient cutting device for the traction pipe is needed to meet the requirements. Summary of the Utility Model

[0018] As Figure 1-2 shown, the present invention provides a technical solution: a cutting device for the incision of a traction pipe used for extrusion bonding of a pipeline, including a cutting component 2 distributed above the traction pipe 1, a mounting frame 3, a height adjustment mechanism 4, a protection mechanism 5, and a support mechanism 6 distributed below the traction pipe 1, which can be adjusted as needed.

[0019] The cutting component 2 includes a cutter 21 and a hydraulic drive cylinder 22. The movable end of the hydraulic drive cylinder 22 is fixed to the tool holder end of the cutter 21. The upper connecting plate 31 and the lower connecting plate 32 of the mounting frame 3 are connected by a connecting column 33. The hydraulic drive cylinder 22 is fixed on the upper connecting plate 31 of the mounting frame 3. The tool holder of the cutter 21 is slidably connected to the lower connecting plate 32 of the mounting frame 3. The cutting edge of the cutter 21 extends below the mounting frame 3. During the incision process, the cutting edge of the cutter 21 is adjusted downward by the height adjustment mechanism 4 to a height close to the traction pipe 1, and is adjusted upward when not in use to avoid occupying space.

[0020] The protection mechanism 5 is connected to the mounting frame 3 and is distributed on both sides of the cutter 21. The cutter 21 is received between the protection mechanisms 5 on both sides. The protection mechanism 5 includes protection plates 51 and spring members 52 distributed on both sides of the cutter 21. The cutter 21 is received between the protection plates 51 on both sides. The upper ends of the protection plates 51 penetrate upward through the lower connecting plate 32 and are movably sleeved on the connecting column 33. The spring members 52 are sleeved on the connecting column 33 and are movably connected between the protection plates 51 and the upper connecting plate 31. Auxiliary wheels 511 are provided at the bottoms of the protection plates 51 on both sides of the cutter 21. The protection mechanism 5 is mounted on the traction pipe 1 through the auxiliary wheels 511 to assist in the incision, improving the stability during the incision process. The protection plates 51 have a safety protection function on both sides of the cutter 21 to avoid accidental injury by the cutting edge of the cutter 21.

[0021] Both the height adjustment mechanism 4 and the support mechanism 6 are connected to a vacuum box 7. The height adjustment mechanism 4 is a hand-cranked lead screw adjustment mechanism. The lifting blocks of the hand-cranked lead screw adjustment mechanism are respectively connected to the lead screw and the guide post. By manually rotating the handle, the lifting block can be driven to vertically lift. The cutting component 2 and the protection mechanism 5 are both integrally connected to the lifting block of the height adjustment mechanism 4 through the mounting frame 3, and the cutting component 2 and the protection mechanism 5 are inclined along the incision direction of the traction pipe 1. During the incision, the traction pipe 1 is cut along the incision direction to form a horseshoe-shaped incision.

[0022] The upper end of the support mechanism 6 supports the traction pipe 1 upward. The support mechanism 6 includes a hand-cranked lead screw 61, an inner thread sleeve fixing seat 62, and a bracket 63.
