End sheath for processing copper corrugated pipe

Abstract

The invention discloses an end sheath for processing a copper corrugated pipe, which is arranged on helical corrugation forming equipment for the copper corrugated pipe. A copper pipe liner (2) is arranged on the helical corrugation forming equipment, a copper corrugated pipe (1) is sleeved on the copper pipe liner (2), an annular clearance is formed between the inner wall of the copper corrugated pipe (1) and the copper pipe liner (2) on the cross section of the copper corrugated pipe, and the round sheath part of the sheath is inserted into the annular clearance between the inner wall of the copper corrugated pipe (1) and the copper pipe liner (2). By using the technical proposal, the inner wall and the pipe opening of the copper corrugated pipe can not be scratched in the case of roll extraction of helical corrugation, so as to ensure product quality. Moreover, the sheath has the advantages of simple structure, convenient operation and use, and low cost.

Description

Technical field [0001] The invention belongs to the technical field of metal material processing, and relates to process equipment for the forming and processing of copper pipes. More specifically, the invention relates to an end sheath of processing copper corrugated pipes. Background technique [0002] In air-conditioning equipment, it is necessary to process the copper pipe into a spiral groove-shaped corrugation. There is no standardized general-purpose equipment for this kind of processing. Enterprises have manufactured some non-standard special equipment according to their own conditions. They use multiple rollers to press on the surface of the copper pipe, the copper pipe rotates, and the roller feeds along the axis of the copper pipe. , The straight copper pipe is rolled into a corrugated pipe with spiral grooves. [0003] In this type of equipment, copper pipe lining rods are used to support the copper corrugated pipe during rolling to prevent the copper pipe from being c...

AI Technical Summary

Problems solved by technology

In this way, there is an annular gap between the inner wall of the straight pipe part of the copper bellows and the copper pipe lining rod, especially at the nozzle part of the copper bellows, due to the rotational movement of the copper bellows, the nozzle and the copper pipe lining rod Impact and scratches occur, causing scratches on the inner wall of the copper bellows

In addition, the copper bellows needs to use its end for axial positioning, and the impact between the port and the positioning piece will occur, causing damage to the nozzle of the copper bellows

The above phenomenon will lead to unqualified copper bellows quality
