Abstract

The invention relates to the technical field of pipe expansion machining, and provides pipe expansion machining equipment. The equipment comprises a machine body, an upper die body and a lower die body, the upper die body and the lower die body slide on the machine body, a pipe expansion cavity is formed by the upper die body and the lower die body and used for containing a to-be-expanded pipe, the pipe expansion machining equipment further comprises a liquid outlet head and a blocking head, the liquid outlet head is slidably arranged in the pipe expansion cavity and extends into the to-be-expanded pipe, the blocking head is slidably arranged in the pipe expansion cavity, and the blocking head, the liquid outlet head and the inner wall of the to-be-expanded pipe form a first liquid containing cavity. Through the technical scheme, the problems that in the prior art, the length of the to-be-expanded pipe is large, and pipe expansion is not easy to achieve are solved.

Description

technical field [0001] The invention relates to the technical field of tube expansion processing, in particular to a tube expansion processing equipment. Background technique [0002] The diameter expanding (bulging) process is a processing method that relies on the stretching of the material to expand the hollow part or tube blank with a smaller diameter outward in the radial direction. Diameter expansion is one of the metallurgical terms. It is a pressure processing process that uses hydraulic or mechanical force from the inner wall of the steel pipe to expand the steel pipe radially outward. There are two methods of thermal expansion and cold expansion. [0003] Most of the existing diameter expansion methods are to put the tube to be expanded into the mold, and by pouring liquid into the mold, the diameter of the pipeline is expanded to the shape in the mold by hydraulic means. This method can not only expand the diameter, but also The pipe can be processed into the des...
