Example Embodiment

[0030] As an embodiment of the invention, the side wall of the clamping block 134 close to the center point of the gear disc 131 is an arc wall; A first cavity 21 is opened in the clamping block 134; The gear disc 131 is fixedly connected with a set of negative pressure machines 2; The arc wall of the clamping block 134 is fixedly connected with a first rubber layer 22; The side wall of the first cavity 21 close to the arc wall of the clamping block 134 is provided with a first through hole 23; The first through hole 23 penetrates the first rubber layer 22; The negative pressure machine 2 and the first cavity 21 are connected with each other; During operation, the outer surface of the PVC pipe itself is relatively smooth. When the clamping block 134 clamps and fixes the PVC pipe, it is necessary to apply a large extrusion force to ensure the fixing effect of the clamping block 134 on the PVC pipe and prevent the PVC pipe from slipping. However, the large extrusion force is easy to...

Abstract

The invention belongs to the technical field of PVC pipelines, and particularly relates to a PVC pipeline cutting device which comprises a workbench. The workbench is fixedly connected with a fixed block; a clamping rotating piece is arranged on the side wall of the fixed block; the clamping rotating piece comprises a gear disc; the gear disc is rotationally connected to the side wall of the fixing block. A power gear is arranged on the side wall, close to the gear disc, of the fixing block. The power gear is meshed with the gear disc; the inner wall of the gear disc is fixedly connected with a set of clamping blocks through electric telescopic rods. A lifting cutting mechanism is arranged at the top end of the fixed block; the lifting cutting mechanism comprises a hydraulic cylinder and a cutting disc; the invention provides a PVC pipeline cutting device, and aims to solve the problems that when a PVC pipe with a large inner diameter is cut, manual sawing or electric saw cutting is generally adopted, but when the method is used for cutting, the cutting surface of the PVC pipe is not smooth enough, and leakage is caused when the PVC pipe is in butt joint.

Description

technical field [0001] The invention belongs to the technical field of PVC pipes, in particular to a PVC pipe cutting device. Background technique [0002] PVC pipe is a polyvinyl chloride pipe, which is extruded by hot pressing after combining polyvinyl chloride resin with stabilizers and lubricants. It is the earliest plastic pipe that has been developed and applied. PVC pipes have strong corrosion resistance and are easy to bond. , low price, hard texture, currently widely used in municipal, construction, water supply and drainage, chemical industry and other fields, used to transport heating fluid and cooling fluid, food, ultra-pure liquid, mud, gas, compressed air; in actual use, it is necessary to PVC pipe cutting, common cutting methods include manual sawing, chainsaw cutting, planetary cutting and other methods. [0003] There are also some technical solutions about PVC pipe technology in the prior art. For example, a Chinese patent with application number 201710946...
