电磁成形是一种高速高能成形方法,从六十年代起应用于生产,并在生产中不断得到发展。在我们国内,由于各种原因,对电磁成形的研究较少。本文拟对电磁成形的原理和方法、电磁成形机的基本结构以及国外电磁成形技术在工业生产中的应用等作一介绍。一、电磁成形的基本原理和方法电磁成形的能量是贮藏在高压电容器中的电能,其基本线路图如图1(a)所示。电源通过充电电路升压、高压整流,把电能贮存于高压电容器组C中,电容器的充电电压通常为
Electroforming is a high-speed and high-energy forming method that has been used in production since the 1960s and continuously evolved in production. In our country, due to various reasons, less research on electromagnetic forming. This article intends to introduce the principle and method of electromagnetic forming, the basic structure of electromagnetic forming machine and the application of foreign electromagnetic forming technology in industrial production. First, the basic principles and methods of electromagnetic forming Electromagnetic forming energy is stored in high-voltage capacitors in the electrical energy, the basic circuit diagram shown in Figure 1 (a) below. Power through the charging circuit boost, high-voltage rectifier, the energy stored in high-voltage capacitor C, the capacitor charging voltage is usually
