Perforating device for PVC pipeline

Abstract

The invention belongs to the technical field of perforating devices, and particularly relates to a PVC pipeline perforating device which comprises a pipe body and a drill bit, wherein a fixing ring is arranged on one side of the drill bit, a supporting plate is arranged at the top end of the side wall of the fixing ring, a pneumatic push rod is arranged on the side wall of the supporting plate, a push plate is connected to the other end of the pneumatic push rod, an arc-shaped plate is connected to the bottom end of the push plate, and the side wall, close to the pipe body, of the arc-shaped plate is attached to the outer wall of the pipe body, a water inlet pipe and a water outlet pipe are installed at the two ends of the pipe body respectively, the water inlet pipe is connected with an external water pump, and a filter plate is installed in the water outlet pipe. According to the device, the effective and comprehensive cooling effect is achieved during perforating of the surface of the pipe body, the situation that the perforating quality of the pipeline is affected due to the poor cooling effect during perforating of the pipe body is prevented, waste of water resources can be reduced, and meanwhile, chippings falling into the pipe body can be conveniently cleaned, and the practicability is high. The energy-saving performance and practicability of the pipeline perforating device during use are improved.

Description

technical field [0001] The invention belongs to the technical field of punching devices, in particular to a PVC pipe punching device. Background technique [0002] Among non-metallic pipelines, plastic pipes are the most widely used. There are many types of plastic pipes, which are divided into two categories: thermoplastic pipes and thermosetting plastic pipes. There are thermoplastic pipes, such as polyvinyl chloride pipes, polyethylene pipes, polypropylene pipes, polyoxymethylene pipes, etc.; there are phenol plastic pipes that are thermosetting. Plastic pipes have the advantages of good corrosion resistance, light weight, convenient molding, and easy processing. Therefore, plastic pipes have been more and more widely used in construction projects. During the processing of plastic pipes, sometimes it is necessary to punch plastic pipes. Hole processing, due to the low melting point of plastic pipes, the temperature is too high during the drilling process, it is easy to ...

Problems solved by technology

[0004] However, the debris produced by the pipeline drilling device in the above technology is easy to fall inside the pipeline, affecting the normal use of the pipeline, and cooling the pipeline by spraying water at the position of the drilling will also cause damage to water resources. waste, and it is also easy to cause incomplete cooling
