Forming method for self-supporting air blowing pipeline

Abstract

The invention belongs to the technical field of pipelines and relates to a forming method for a self-supporting air blowing pipeline. The forming method for the self-supporting air blowing pipeline is characterized by comprising the following steps that when the self-supporting air blowing pipeline is manufactured, a reinforcing piece is made to penetrate through a reinforcing piece hole and also penetrate through a machine head, an inner pipe wall body is made to penetrate through an inner pipe via hole and also penetrate through the machine head, a mold core and a mold sleeve in the machine head are combined, molten plastic in the plastic extruding machine head is extruded outside the reinforcing piece and the inner pipe wall body, and through the combination of the mold core and the mold sleeve, a self-supporting body is manufactured outside the reinforcing piece through extrusion, an outer pipe body is manufactured outside the inner pipe wall body through extrusion, and the self-supporting body and the outer pipe body are connected through a connecting rib; the integrally-formed self-supporting air blowing pipeline is made to penetrate through a forming mechanism, the self-supporting body is located in a self-supporting body containing groove, the connecting rib is located between rib containing columns, the outer pipe body is located in an outer pipe containing groove, and the self-supporting body, the connecting rib and the outer pipe body cannot rotate in a cooling water tank. The forming method for the self-supporting air blowing pipeline mainly has the following beneficial effects that the pipeline construction speed is higher, the service life of the pipeline is longer, the quality of the pipeline is more stable, and the appearance is more attractive.

Description

[0001] This application is a divisional application for an invention patent titled: Self-supporting air-blown pipeline molding device and molding method, filing date: May 26, 2014, and application number: 201410224418.0. technical field [0002] The invention belongs to the technical field of pipes, in particular to a forming device for a self-supporting air blowing pipe. Background technique [0003] With the rapid development of electric power, communication and other industries, more and more cables are laid. On the one hand, because a large number of cables were laid overhead, the cables in the sky are very messy, which affects the appearance of the city. , has brought great potential safety hazards; for this reason, the country has promulgated corresponding laws, regulations and instructions, and the cables need to be laid in the ground. Cables are laid underground mainly through pipes and direct burial. The direct burial method requires excavation of the ground and req...
