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, in particular to an electromagnetic drive forming method and device. Background technique [0002] The requirements of energy saving and environmental protection have prompted high-strength lightweight alloy materials represented by aluminum alloys to be widely used in the field of advanced manufacturing. However, the traditional forming technology encounters major obstacles in the processing and application of high-strength light alloy materials, mainly because the light alloy has poor plasticity and is difficult to form, and a new forming technology is urgently needed. [0003] Studies have shown that when forming at a high rate, the formability of the material is significantly improved, and this formability improved due to high-speed processing is called "Hyperplasticity". Electromagnetic forming is a rapid manufacturing technology that uses Lorentz force to form metal materials. It belongs...
