Abstract

The invention relates to a pipe expanding device. The pipe expanding device comprises a die holder and a pipe expanding core print, wherein the die holder comprises a cavity of which one end is closed and the other end is opened, and is connected with a bearing; the pipe expanding core print is mounted in the cavity of the die holder in an inserting manner through a core holder. According to the technical scheme adopted by the invention, the pipe expanding core print is fixed on the die holder through the core holder, and the tail end of a pipe blank to be expanded is abutted through a baffle, so that the pipe blank is fixed; the bearing pushes the die holder and drives the pipe expanding core print to move forwards, so that the pipe expanding core print penetrates through an inner cavity in the pipe end of the pipe blank, and the inner cavity of the pipe end is expanded. The pipe expanding core print is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a tube expanding device. Background technique [0002] The existing method of expanding the tube blank mainly adopts stamping or hydraulic method. The tube expansion device used in this method has a complex structure, and is not suitable for the expansion of short-distance tubes, so it causes more waste products and lower yield. Contents of the invention [0003] The object of the present invention is to provide a tube expansion device with simple structure. [0004] The object of the present invention is achieved in this way. A tube expansion device includes a mold base and an expander mandrel head. The mold base includes a cavity with one end closed and the other end open and connected to a bearing. Inserted in the cavity of the mold base. In this technical solution, the expansion tube core head is fixed on the mold base through the core base, and the tail end of the tube blank to be expanded is resisted by the baffle to...
