Pipe fitting magnetic pulse impact forming device

Abstract

The invention discloses a pipe fitting magnetic pulse impact forming device, relates to a metal material machining forming device, and aims to overcome the problems that existing magnetic pulse forming precision is not high and single-time discharge forming is difficult to realize. The pipe fitting magnetic pulse impact forming device comprises a die unit, a hydraulic unit, a compression unit andan impact unit, wherein the die unit comprises an upper die and a lower die; the upper die is provided with an upper die through hole with a downward opening; the lower die is provided with a lower die through hole with an upward opening; the upper die is positioned above the lower die; a pipe fitting to be machined is transversely placed between the upper die and the lower die; the hydraulic unitcommunicates with the pipe fitting to be machined to form a circulating passage which is used for injecting or recovering viscous mediums into the pipe fitting to be machined; the compression unit comprises a first piston unit and a second piston unit, and the first piston unit and the second piston unit are respectively positioned at the two ends of the pipe fitting to be machined and used for providing impact force along the axial direction of the pipe fitting to be machined inside the pipe fitting to be machined; and the impact unit is used for providing impact power of the compression unit.

Description

technical field [0001] The invention relates to a metal material processing and forming device, in particular to a magnetic pulse two-way impact forming device for an aluminum alloy three-way / four-way pipe fitting. Background technique [0002] With the demand for lightweight structures in the fields of automobiles, aerospace, and pipeline engineering, more and more aluminum alloy pipe fittings of various shapes are used. However, the processing of aluminum alloy materials is difficult, and the traditional processing technology can no longer meet the technical requirements. The magnetic pulse forming technology will be widely used because of its technological advantages, which conform to this development demand. Magnetic pulse forming is a high-speed forming process. With its high-speed forming process characteristics, it can greatly improve the forming ability of some difficult-to-form materials at room temperature. [0003] Viscous medium bulging is a bulging process that...
