A processing tool for pipe fittings

Abstract

The invention provides a machining tool of pipe fittings and belongs to the technical field of machinery, aiming at solving the problems of an existing inner and outer circle chamfering device for machining the pipe fittings that the machining precision is not high, the assembling is not convenient and the like. The machining tool of the pipe fittings comprises a base and a machining disc mounted on the base, wherein a plurality of convex inner chamfering blocks and outer chamfering blocks are integrally formed on the machining disc; an inner chamfering cutting surface is arranged on the outer side of each inner chamfering block, and an outer chamfering cutting surface is arranged on the outer side of each outer chamfering block; the inner chamfering blocks and the outer chamfering blocks are uniformly distributed in the peripheral direction by taking the center of the machining disc as the circle center; and the inner chamfering blocks and the outer chamfering blocks are arranged at intervals. The machining tool has the advantages that the chamfering angle of the pipe fittings is improved, the assembling is convenient and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a processing tool for pipe fittings. Background technique [0002] At present, the production and use of plastic pipes used as various liquid transportation pipelines has become more and more common in modern economic construction. In some fields, plastic pipes have gradually replaced metal pipes and are widely used in chemical industry, agriculture, Municipal, construction and mining industries. The connection methods of plastic pipes include socket rubber ring connection, adhesive connection and flange connection, among which the socket rubber ring connection method is the most widely used. When using the socket rubber ring connection method, first The more important part to do is to chamfer the inner and outer walls of the port of the plastic pipe. [0003] In the existing production of plastic pipes, manufacturers basically use manual methods to chamfer the ports of the plas...

Problems solved by technology

[0005] However, in the above-mentioned inner and outer round chamfering devices, the inner chamfering knife and the outer chamfering knife are separately arranged, and the inner chamfering knife and the outer chamfering knife need to be installed and fixed separately during assembly. This makes the assembly of the chamfering device more complicated, and when the chamfering knife needs to be replaced after being used for a long time, the entire chamfering device needs to be dismantled before it can be replaced.
