Port forming machine

Abstract

The invention aims to provide a port forming machine. The port forming machine is characterized in that an inner telescopic device and an outer telescopic device are arranged on the same axis; the inner telescopic device is provided with an inner mould composed of a plurality of inner petal mould bodies at an opening fastening portion, and the inner mould realizes the expansion and contracting motions through an inner telescopic rod; and the outer telescopic device is provided with an outer mould composed of a plurality of outer petal mould bodies at the opening fastening portion and comprises an outer mould thruster, and the outer mould moves in the radial direction through the outer mould thruster to complete expansion and contracting motions. The design key points of the technical scheme lie in that the inner mould and the outer mould move in the same radial plane at the opening fastening portion, the inner mould and the outer mould are combined through a split petal structure, and a weaving component is fixed to a port of a corrugated pipe component through an end cap within a certain diameter range. The power of the inner mould and the outer mould is from driving devices moving on the same axis, and the moving directions of the inner mould and the outer mould are switched through an inner mould taper rod and the outer mould thruster.

Description

technical field [0001] The invention relates to mechanical equipment technology, in particular to a port forming machine used for the set forming of end caps of automobile exhaust flexible pipes. Background technique [0002] The invention of Chinese patent application number: 201410085210.5 discloses a flexible pipe fitting for automobile exhaust pipe, which includes: a bellows member made of metal material and formed in the shape of a hollow cylinder, and in The bellows member has corrugations repeatedly formed in a wave form; an interlocking member located in the bellows member with a predetermined gap with the bellows member and spirally formed on the interlocking member A helical groove is formed to absorb deformation; a braided member positioned such that the braided member surrounds the outer side of the bellows member and braided such that the braided member is capable of displacement and tension with respect to the direction of compression flexibly deformed with a ...

AI Technical Summary

Problems solved by technology

The cap member is the end cap; the structure of the pipe expansion and contraction machine can be understood from a copper pipe automatic expansion and contraction machine disclosed by the patent announcement number CN2860663Y; the traditional pipe expansion and contraction machine is suitable for single tube expansion and contraction , is not suitable for the shortage of fixing the braided member to the outer circumference of the port of the bellows member by the end cap that fits outside, therefore, designing a method that is suitable for fixing the braided member to the bellows A port forming machine for the outer circumference of the port of the component has become an urgent problem to be solved
