Pipe end hydraulic forming device for automobile pipe

Abstract

The invention discloses a pipe end hydraulic forming device for an automobile pipe, and belongs to the field of automobile pipe machining equipment. The device comprises a hydraulic die and a clamping die which are arranged on a worktable. The hydraulic die comprises a die base, a die column and a hydraulic oil cylinder, the die column is axially and horizontally arranged on the die base in a sliding mode, and a piston rod of the hydraulic oil cylinder is connected with the die column. The clamping die comprises an upper die block, a lower die block and a clamping hydraulic oil cylinder, the upper die block is connected with a piston rod of the clamping hydraulic oil cylinder, the upper die block and the lower die block are provided with an upper clamping groove and a lower clamping groove respectively, and the upper clamping groove and the lower clamping groove correspond to a pipe to be machined in shape. An abutting die comprises a base and an abutting column installed in an installing hole of the base, and the abutting column sequentially comprises an abutting plate, a threaded column and a hand wheel. By means of the pipe end hydraulic forming device, the pipe can be reliably clamped, a die core and a die sleeve can be replaced conveniently, the application range is wide, continuous machining of the pipe end can be achieved, and production efficiency is improved.

Description

technical field [0001] The invention relates to a processing equipment for automobile pipe fittings, in particular to a hydroforming device for pipe ends of automobile pipe fittings. Background technique [0002] At present, in the production of pipe fittings such as automobile pipe fittings, it is necessary to shrink or expand the pipe ends of the pipe fittings, and the pipe fittings are irregular special-shaped pipes, and have different shapes according to different models, because the pipe fittings are hollow thin metal pipes , the existing device for fixing pipe fittings is to set two or more fixtures for fixing. During the compression molding process of the end of the pipe fittings, due to the local fixation, the pipe fittings are prone to displacement due to strong thrust, and pinch marks are left on the surface of the pipe fittings. Existing pipe end hydraulic molds are designed to be non-detachable, and the mold core and mold sleeve cannot be replaced according to ne...

AI Technical Summary

Problems solved by technology

Existing pipe end hydraulic molds are designed to be non-detachable, and the mold core and mold sleeve cannot be replaced according to needs, and one machine cannot be used for multiple purposes, and the same equipment can process different pipe fittings or pipe end shapes; Once the processing is in place, two devices need to be used for two processing, two installation and disassembly are required, continuous processing cannot be realized, and working hours are delayed
