Pipe socket forming method

Abstract

The invention discloses a pipeline socket forming method. The method comprises the following steps: (1) wiring: arranging a resistance wire on the peripheral wall of a forming mould according to a preset arrangement path; (2) forming: forming a pipeline socket on the forming mould on which the resistance wire is arranged; (3) mould unloading. The pipeline socket forming method adopts process steps of wiring and then forming the pipeline socket. Compared with the traditional process steps of forming the pipeline socket and then wiring, the pipeline socket forming method has the advantages that 1, the resistance wire is arranged in advance, so that the arrangement path of the resistance wire is convenient and adjustable; 2, in the forming process of the pipeline socket, the resistance wire is directly buried in a plastic layer of the pipeline socket and is flush with the inner surface of the plastic layer, and the inner surface of the pipeline socket is smooth and flat and can be matched with a pipeline insertion opening well.

Description

technical field [0001] The invention belongs to the technical field of pipeline connection, in particular to a method for forming a pipeline socket. Background technique [0002] The Chinese patent application with the publication number CN 103672276A discloses a pipe hot-melt wiring method, which includes the following steps: in the area where the plastic pipe needs to be welded, use a wiring knife to inlay metal wires at both ends of the plastic pipe according to the corresponding wiring pitch The plastic surface of the outer diameter or inner diameter is covered with the area to be welded. A section of the two ends of the metal wire is reserved to be exposed outside the plastic surface. After the metal wire is laid, it is welded. After the welding is completed, the The metal wire ends exposed outside the plastic surface layer of the plastic pipe are cut off. [0003] That is, when the existing pipe socket is processed, the pipe socket is formed first, and then the resist...

Problems solved by technology

Although the resistance wire arranged by this method can meet the requirements of use to a certain extent, the resistance wire is mechanically fixed in the inner hole of the pipe socket. On the one hand, it will make it difficult for the pipe socket to be inserted into the pipe socket during installation and construction; on the other hand On the one hand, even if the pipe socket is barely inserted into the pipe socket, there is still the problem that the pipe socket and the pipe socket are not tightly matched, which leads to poor connection quality between the pipe socket and the pipe socket

In addition, the existing resistance wire wiring method of forming the pipe socket first and then arranging the resistance wire still has the defects of complex production process, low degree of automation, and heavy dependence on the proficiency of workers
