高速冲孔基本原理在板材上加工出各种形状不同尺寸的孔,一般用凸凹模在压力机上进行冲裁。这里介绍一种利用火药点燃产生的气体,来完成冲孔的加工方法。完成这种工艺的装置如图1。 The basic principles of high-speed punching plate processed in a variety of shapes of different sizes of holes, generally punch with punch on the press. Here is a use of gunpowder gas generated to complete the punching processing methods. The device to complete this process is shown in Figure 1.
