Problems solved by technology

At present, to achieve hydraulic bulging of multi-way tubes, special pressure source equipment must be used to provide high pressure inside the pipe. The existing technology for realizing multi-way tube hydraulic bulging is expensive and costly, and the cycle of pressurization and pressure relief is long, and the forming speed is high. Too slow, and the metal tube will rebound after pressure relief, which affects the forming accuracy. In addition, the hydraulic bulging has poor forming quality when it has small features such as complex sections and rounded corners. The promotion and application of multi-way tube hydraulic bulging technology caused great inconvenience

Abstract

The invention discloses a device and device for progressive impact hydraulic forming of a multi-way pipe. The device comprises a base and a die arranged on the base; the die is provided with a group of radial punches and a group of axial punches; and the radial punches and the axial punches extend into a die cavity of the die. The device is low in cost, good in applicability and capable of improving the forming limit and the forming quality of the pipe, especially the forming quality of the multi-way pipe with the characteristics of small fillets and small bosses. The method can shorten the forming period and improve the production efficiency.

Description

Technical field [0001] The present invention relates to hydraulic bulging the metal tube technology, in particular for multi-way progressive shock tube apparatus and method for hydroforming molding. Background technique [0002] Multi-pass tube is a fluid shunt device, widely used in petrochemical, aerospace, automotive, appliance and other industries. Bulging multi-pass technique is to use a liquid medium as a molding, by means of high pressure presses and a source device, so that tube bulging out in a mold manifold, the manifold to the top cut to obtain a molded multi-way tube technology. Multi-pass tube surface hydroforming process the obtained good quality, excellent mechanical properties, high material utilization. Currently multi-pass Bulging pressure source must use special equipment to provide high pressure inside the pipe, the prior art multi-way achieve Bulging expensive equipment, high cost, long cycle and pressurized and relief, forming speed too slow, and the metal t...
