Abstract

The invention provides an electromagnetic drive forming method and an electromagnetic drive forming device. In the method, pulse electromagnetic force is used for driving a composite punch to quickly impact a workpiece, so that the workpiece is attached to a female die to finish high-accuracy formation. The device comprises a drive coil, a power supply control system, the composite punch, a punch positioning mold and pressure equipment. By the method and the device, the problems of low film lamination performance and low efficiency during electromagnetic formation in the prior art are solved, and the efficiency of converting electromagnetic energy into kinetic energy is greatly improved.

Description

Technical field [0001] The invention belongs to the field of material processing, and particularly relates to an electromagnetic drive forming method and device. Background technique [0002] The requirements of energy saving and environmental protection have promoted the widespread application of high-strength lightweight alloy materials represented by aluminum alloys in the field of advanced manufacturing. However, traditional forming technology has encountered major obstacles in the processing and application of high-strength lightweight alloy materials, which are mainly reflected in the difficulty of forming lightweight alloys due to poor plasticity, and a new forming technology is urgently needed. [0003] Studies have shown that when high-speed forming, the forming performance of the material is significantly improved. This improved formability due to high-speed processing is called "Hyperplasticity". Electromagnetic forming is a rapid manufacturing technology that uses Lore...
