Description

Technical Field

[0001] The utility model relates to the technical field of chamfering machines, in particular to a plastic pipe chamfering machine. Background Art

[0002] Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, plastic pipes have the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, simple construction and maintenance, long service life, etc. They are widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, electricity and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. In the process of plastic pipe processing, it is usually necessary to use a chamfering machine to chamfer the ends of the pipes.

[0003] At present, when a chamfering machine is used to chamfer the end of a pipe, workers usually insert the plastic pipe into the chamfering machine and then fix the pipe by hand, which requires a lot of manpower and is difficult to ensure the stability of the pipe. In addition, some grinding debris will be generated during the chamfering process. The debris will accumulate on the table or float in the air, affecting the environmental quality. For this reason, we have designed a plastic pipe chamfering machine to solve the above problems. Utility Model Content
