Abstract

The invention discloses an electromagnetic forming device and method based on modular magnetic traps. The electromagnetic forming device comprises a forming coil, a die, a workpiece and a plurality ofmagnetic trap modules. The workpiece and the die are placed adjacently, the modular magnetic traps and the workpiece are placed adjacently, an electromagnetic coil and the modular magnetic traps areplaced adjacently, and a power supply is connected with the forming coil through a cable. When a power supply switch is turned off, a pulse current passes through the forming coil, thus a pulsed magnet field is generated around, and the pulsed magnet field concentrates electromagnetic force in a target forming area through the magnetic concentrating effect of the modular magnetic traps to realizeexpected deformation behavior; and according to different forming needs, the different magnetic concentrating effects are achieved through flexible combination of the multiple magnetic trap modules. Through a modular work mode of the magnetic traps, an electromagnetic forming force field is effectively controlled, the flexibility of adjusting and control over the force field can be improved, the equipment cost is lowered, the various rich forming needs can be met through a single set of equipment, and the flexibility of the process is significantly expanded.

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 based on a modular magnetic collector. Background technique [0002] The global energy crisis has made light alloy materials such as aluminum alloys widely used in various industrial fields. However, light alloy materials have low forming plasticity at room temperature, and the processing effect of traditional processing technology is not ideal. Electromagnetic forming technology can greatly improve metal forming performance due to factors such as high forming rate, and is an important method to realize the processing of lightweight materials such as aluminum alloy. [0003] At present, the development of electromagnetic forming technology is severely limited by the forming flexibility of equipment. Although in theory, any electromagnetic force distribution can be realized by changing the geome...
