Special-shaped wall pipe holder, socket forming mould and bell and spigot manufacturing equipment

Abstract

The invention relates to a special-shaped wall pipe holder, a socket forming mould and bell and spigot manufacturing equipment, aiming at solving the problem of no special equipment. The socket forming mould comprises a first cylinder assembling body, a second cylinder assembling body, a third cylinder assembling body, an optical shaft tensioning rod and a long shaft which form an integer through mutual matching. According to the socket forming mould, two pairs of arc-shaped plates inside the second cylinder assembling body can be controlled through the long shaft, so that the size and the circular degree of the second cylinder assembling body can be regulated; the manufacturing equipment is formed through the matching of other auxiliary mechanisms, so that automatic manufacturing operation can be realized; especially, the requirement on manufacture of a steel-plastic combined bell and spigot can be realized, and the requirement on manufacture of the bell and spigot of a large-caliber special-shaped wall pipe can be met.

Description

technical field [0001] The invention relates to the technical field of manufacturing drainage pipes, in particular to a mold for forming sockets and sockets of special-shaped wall pipes and manufacturing equipment for sockets and sockets. Background technique [0002] Special-shaped wall pipes in the field of drainage pipes generally include double-wall corrugated pipes, double-wall corrugated pipes, steel belt reinforced spiral wound pipes, inner and outer double flat wall pipes, steel-plastic composite pipes, hollow wall winding pipes, molded drainage pipes, etc. Among them, the processing of pipe joints is a complex structure, which is illustrated by taking the spirally wound pipe as an example: [0003] Spiral wound pipe is a kind of pipe with high strength, and its structure has spiral reinforcing ribs on the outer surface to form spiral protrusions. The traditional pipeline connection method, one is to use steel hoops to connect, this method needs to use a more compli...

AI Technical Summary

Problems solved by technology

The traditional pipe connection method, one is to use steel hoops to connect, this method needs to use a more complicated connection structure, which is disclosed in Chinese patent CN202532040U

The second is to use sockets for connection. The design of traditional sockets is too complicated to form, and the problems of low production efficiency, high cost, and variability of large-diameter sockets are difficult in the manufacturing process.

Moreover, in the molding process, the degree of automation is not high, the size is not precise, and the problem of unreliable socket connection is prone to occur.
