Water swelling forming machine for special-shaped pipes

Abstract

The invention discloses a water swelling forming machine for special-shaped pipes. The water swelling forming machine for special-shaped pipes comprises a machine frame, a forming liquid storage device, a booster injection device and a mold. A lateral cylinder guide groove with the guide axis perpendicular to the lifting axis of a movable cross beam is formed in the machine frame. The lateral cylinder guide groove is provided with at least two lateral pushing devices. Each lateral pushing device comprises a transverse adjusting base, a circumferential adjusting base and a lateral cylinder which are stacked in sequence, wherein the transverse adjusting base is located on the lateral cylinder guide groove, and internally provided with a guide adjusting block embedded in the lateral cylinder guide groove and a plurality of circumferential adjusting holes facing the circumferential adjusting base; the circumferential adjusting base is located on the transverse adjusting base, and internally provided with circumferential adjusting blocks rotationally connected to the interiors of the circumferential adjusting holes; and the lateral cylinder is arranged on the circumferential adjusting base, and provided with a piston rod capable of reciprocating to get close to the mold, the piston rod is provided with a pusher block, and the pusher block communicates with the booster injection device. The water swelling forming machine for special-shaped pipes has the advantages of being capable of machining special-shaped pipes, high in applicability, convenient to operate and the like.

Description

technical field [0001] The present invention relates to water swelling forming equipment, in particular to a water swelling forming machine for special-shaped pipe fittings. Background technique [0002] Internal high pressure forming, also known as hydroforming or hydraulic forming, is a material forming process that uses liquid as a forming medium to achieve the purpose of forming hollow parts by controlling internal pressure and material flow. It is widely used in automobile, aviation, aerospace manufacturing, hardware manufacturing and other fields, especially in automobile production, such as the processing of car sub-frames, instrument panel brackets, rear sub-frame reinforcement pipes, hot-end exhaust manifolds and other parts All have gradually adopted the internal high pressure hydroforming process to replace the traditional processing technology. [0003] At present, more and more special-shaped parts such as stainless steel faucets, brass faucets, plumbing and sa...

AI Technical Summary

Problems solved by technology

When the water expansion molding machine needs to realize the bulging of products of different sizes, the workers need to readjust the angle and position of the side cylinder and drill the corresponding screw holes to fix the side cylinder. This adjustment method is cumbersome and increases the difficulty of adjusting the feeding side cylinder.
