Pipe expanding device and pipe expanding equipment

Abstract

According to the pipe expanding device and the pipe expanding equipment, when the pipe expanding device and the pipe expanding equipment are used, a first driving part drives a positioning part to move, and a second driving part drives an expanding part to move in a positioning channel until the positioning part is arranged on a part to be expanded in a sleeving mode through an insertion opening of the positioning channel; then the second driving piece independently drives the expansion piece to continuously move by a preset distance in the to-be-expanded piece so as to carry out pipe expansion treatment on the to-be-expanded piece; and finally, the first driving piece independently drives the positioning piece to drive the extrusion part to move and pushes the flaring piece to extend into the to-be-expanded piece to carry out flaring treatment through abutting fit between the extrusion part and the flaring piece.

Description

technical field [0001] The invention relates to the technical field of tube expansion, in particular to a tube expansion device and tube expansion equipment. Background technique [0002] During the processing of the evaporator, copper tubes need to be expanded and flared. The traditional method of expanding the copper tubes of the evaporator is to rely on the manual expansion machine to expand the tubes one by one. This expansion method There are big flaws. One is the disadvantages of slow production efficiency, low degree of automation, and high manual work intensity, and the other is the low qualified rate of expansion tubes and high scrap rate. In order to improve the tube expansion efficiency and reduce the scrap rate, the corresponding tube expansion equipment is generally introduced in the production process for automatic tube expansion. During the tube expansion, the expansion rod and the flarer are automatically driven by the corresponding driving device to expand ...

AI Technical Summary

Problems solved by technology

[0004] Based on this, when the traditional tube expansion equipment is in use, when the expansion rod and the flarer in the tube expansion equipment are working, the alignment of the expansion rod, the flarer and the opening of the copper tube is prone to deviation, resulting in the qualified expansion of the tube. In order to solve the problems of low production rate and high scrap rate, a tube expansion device and tube expansion equipment are proposed. When the tube expansion device and tube expansion equipment are used, the qualified rate of tube expansion can be improved and the scrap rate can be reduced.
