1、 General introduction of electromagnetic forging press Electromagnetic forging press belongs to high-energy (high-speed) forming technology. First of all, electric energy needs to be stored in high-voltage capacitor. When the high-voltage switch is closed, the capacitor can discharge the coil rapidly (US level) and generate a changing pulse magnetic field around it. When the pulse magnetic field passes through the workpiece, it will generate induction current (eddy current) in the metal workpiece, and the charged metal workpiece is in a rapidly changing magnetic field When the magnetic pressure reaches the yield strength of the material, the metal workpiece will have plastic deformation to achieve the purpose of forming metal parts. Electromagnetic forming technology has the characteristics of easy and accurate control of processing energy, fast forming speed, high precision of forming workpiece, small elasticity of parts after forming, improvement of plastic deformation ability of materials, simple mold and strong universality of equipment, easy to adopt composite process and realize automatic production, green and environmental protection in the whole forming process, which has been widely used in aviation, aerospace, weapon industry Automobile manufacturing, light chemical industry, instruments and electronics and many other fields.
