压塌式保险器是机械压力机中的一个主要易损件。它的作用是保证压力机超载时不致损坏机床的重要零部件,避免恶性设备事故。压力机在无保险器时,禁止工作。按一般规定压力机超载不得超过公称压力的120％,超过则保险器被压塌。但压力机工作次数频繁,冲压的工件经常变换,因而保险器因变形也容易压塌。由于现在压力机通常使用的压塌式保险器加工工艺较差,以JC23—63型压力机保险器 Compression saver is one of the main wearing parts in mechanical presses. Its role is to ensure that the press overload will not damage the important parts of the machine to avoid the accident of malignant equipment. Presses are forbidden to work without fuse. According to the general provisions of the press overload shall not exceed 120% of the nominal pressure, the fuse is more than collapse. However, frequent press work, stamping the workpiece often change, so the fuse is also easy to collapse due to deformation. Because the press is usually used in the collapse of the fuse processing technology is poor, with JC23-63 type press insurance
