Abstract

The invention discloses an electromagnetic forming device and method for metal pipe fittings, belonging to the technical field of metal forming manufacturing, comprising: a plurality of forming coils coaxially arranged inside the metal pipe fitting to be formed; Forming mold; power supply module, including multiple pulse power supplies and discharge sequence control modules, multiple pulse power supplies are connected to multiple forming coils; the pulse power supply is used to pass pulse current to each forming coil, so that induced eddy currents are generated in the metal pipe to be formed , The magnetic field generated by the pulse current and the induced eddy current generate an electromagnetic force, and the metal pipe to be formed is deformed to the shape of the forming mold under the action of the electromagnetic force. The invention obtains different electromagnetic force field distribution characteristics by changing the discharge parameters of a single forming coil, meets different force field requirements, solves the problem of single electromagnetic force distribution characteristics in traditional electromagnetic forming, and can effectively improve the flexibility of electromagnetic forming and the metal Molding accuracy of pipe fittings.

Description

technical field [0001] The invention belongs to the technical field of metal forming and manufacturing, and more specifically relates to an electromagnetic forming device and method for metal pipe fittings. Background technique [0002] Light alloys represented by magnesium, aluminum, and titanium are widely used in automobile manufacturing, aerospace and other fields due to their high-strength and low-density physical properties. However, this type of light alloy has poor formability at room temperature and is prone to wrinkling and cracking. Electromagnetic forming technology is a high-energy, high-speed special forming method that uses pulsed electromagnetic force to plastically process metal blanks. It can greatly improve the forming limit of light alloys and suppress wrinkling. At the same time, it also has simplified molds and high processing accuracy. High, easy to realize the advantages of production automation. Therefore, electromagnetic forming technology has bee...
