Technical Field

[0001] The utility model relates to the technical field of PVC pipeline processing, in particular to a PVC pipeline cutting structure. Background Art

[0002] PVC pipes have been widely used in various water supply networks, building drainage, agricultural irrigation and other fields due to their advantages such as light weight, good hydraulic conditions, long service life and simple installation. However, in the processing and installation of PVC pipes, cutting is a crucial link, and its quality directly affects the overall performance and safety of the pipeline system.

When cutting PVC pipes with thinner walls, the PVC pipes may be deformed due to squeezing, resulting in uneven cuts, which reduces the cutting effect. Therefore, the applicant proposes a PVC pipe cutting structure to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The following embodiments will be combined with the accompanying drawings to describe the utility model in detail. In the drawings or descriptions, similar or identical parts use the same reference numerals, and in actual applications, the shape, thickness or height of each component can be enlarged or reduced. The various embodiments listed in the utility model are only used to illustrate the utility model, and are not used to limit the scope of the utility model. Any obvious modifications or changes made to the utility model do not depart from the spirit and scope of the utility model.

[0022] See also Figure 1-5 As shown, a PVC pipe cutting structure proposed by the utility model comprises a workbench 2 and a limiting mechanism 1 assembled on the top of the workbench 2, as well as a fixing mechanism 3 assembled on the top of the workbench 2 and located on one side of the limiting mechanism 1 and a cutting machine 4 assembled on the top of the workbench 2 and located at the rear end of the limiting mechanism 1. The limiting mechanism 1 comprises a fixing cylinder 101 fixedly mounted on the top of the workbench 2, a plurality of movable arms 103 distributed in a ring array are hingedly mounted on one side of the fixing cylinder 101, a limiting wheel 104 is rotatably mounted on the outer side of each movable arm 103, a screw rod 105 is rotatably mounted inside the fixing cylinder 101, a threaded sleeve 107 is threadedly mounted on the outer side of the screw rod 105, and a movable rod 108 is hingedly mounted between the threaded sleeve 107 and the movable arm 103.

[0023] Based on the above-mentioned structural setting, the PVC pipe cutting structure is composed of a limiting mechanism 1, a workbench 2, a fixing mechanism 3 and a cutting machine 4, wherein the limiting mechanism 1 can conveniently support the inner wall of the pipe cutting position, the fixing mechanism 3 can conveniently fix the pipe body to avoid movement during cutting, the cutting mechanism 4 can facilitate the pipe cutting operation, and the supporting effect of the limiting mechanism 1 on the inner wall can avoid the deformation of thin-walled pipes during cutting. Specifically, in the working process, the pipe to be cut is placed on the fixing mechanism 3 for support, so that one end of the pipe is sleeved on the outside of the limiting wheel 104, and the pipe is pushed so that the limiting wheel 104 corresponds to the incision of the pipe. By rotating the screw rod 105, the threaded sleeve 107 can be driven to move left and right along the screw rod 105, and the threaded sleeve 107 is driven to move left and right. When the pipe is cut, the movable arm 103 can be pushed to flip outward by the movable rod 108, so that the limiting wheel 104 can be in contact with the inner wall of the pipe. The inner wall of the pipe cut can be evenly supported by multiple limiting wheels 104, which can conveniently support and limit the inner walls of pipes with different inner diameters, thereby improving the scope of application. The fixing mechanism 3 can conveniently fix the pipe body, and the cutting machine 4 can be moved forward to facilitate the cutting operation of the pipe. During the cutting process, the supporting effect of the limiting wheel 104 can prevent the cut of the pipe from being easily deformed, thereby improving the cutting effect. After the cutting is completed, the threaded sleeve 107 can be driven to move to the right by rotating the screw rod 105 in the opposite direction, and the movable arm 103 can be pulled together by the movable rod 108, so that the limiting wheel 104 can be separated from the inner wall of the pipe, thereby facilitating the disassembly of the cut pipe.

[0024] Furthermore, a support leg 201 is fixedly installed at the bottom of the workbench 2, and the workbench 2 and the cutting machine 4 are slidably installed through an electric slide rail 202. The support leg 201 can conveniently support the workbench 2, and the electric slide rail 202 can conveniently drive the cutting machine 4 to move forward and backward, so as to facilitate the cutting operation of the pipeline.

[0025] Further, the fixing mechanism 3 includes a support frame 301 fixedly mounted on the top of the workbench 2, and the support frame 301 is fixedly mounted to the workbench 2 via a fixing seat 306. The support frame 301 can conveniently support the pipe body, and the fixing seat 306 can support and fix the support frame 301, so that the support frame 301 can stably support the pipe.

[0026] Further, two movable frames 303 are slidably mounted inside the support frame 301, and a clamping seat 302 is rotatably mounted inside the movable frame 303. The clamping seat 302 can be turned over by the movable frame 303, so that the clamping seat 302 can be attached to the outside of the pipe for clamping operation.

[0027] Furthermore, a threaded rotating rod 304 penetrating the support frame 301 is rotatably installed on the outer side of the movable frame 303, and the movable frame 303 and the support frame 301 are slidably installed via a sliding rod 305. The threaded rotating rod 304 and the support frame 301 are threadedly engaged, and the threaded rotating rod 304 can be rotated to conveniently drive the movable frame 303 to move, so that the clamping seat 302 can clamp and fix the pipe, and the sliding rod 305 can make the movable frame 303 slide horizontally to avoid skewing.

[0028] Furthermore, one end of the screw rod 105 extends out of the fixed cylinder 101 and is fixedly connected to a turntable 106, and the fixed cylinder 101 is fixedly installed with the workbench 2 via a fixed frame 102. The turntable 106 can conveniently drive the screw rod 105 to rotate, and the fixed frame 102 can conveniently support the fixed cylinder 101.
