Abstract

The invention relates to an alloy plate electromagnetic punching and flanging forming method. The alloy plate electromagnetic punching and flanging forming method includes the first step of installing a flat plate spiral coil assembly, the second step of installing a blank, the third step of conducting discharging punching forming, the fourth step of conducting discharging flanging forming, and the fifth step of taking out a formed part. The invention further relates to an alloy plate electromagnetic punching and flanging forming device. An adopted electromagnetic forming tool is simple, no male die needs to be manufactured, and the problems caused by a fit clearance between a female die and the male die are solved. The forming process is completed instantly, ductility and forming limit of materials can be improved, and the problem that cracks are generated in the flanging process can be well solved. Besides, positioning problems caused by die change during multi-procedure forming in existing electromagnetic forming technologies are solved, the problem that cost is increased due to die disassembling and assembling is solved, and production efficiency is greatly improved.

Description

technical field

[0001] The invention relates to an alloy plate electromagnetic punching flanging forming method and device. Background technique

[0002] Stamping is the most common manufacturing and processing technology, usually using a die to apply pressure to the material on a press to separate or deform it. Due to the small gap between the punch and the die in the stamping process, it is difficult to adjust the die, and the friction between the punch and the side of the die and the material increases, and it is difficult to change the die and position during multiple processes, which reduces the service life of the die and increases the cost. At the same time, the lightweight of automobiles and aircraft has gradually become the development trend of the future industry. The application of lightweight and difficult-to-form materials such as aluminum alloys, high-strength steels and composite materials in advanced manufacturing fields such as automobiles and aerospace is i...
