冲床是应用广泛安全性差的一类机床。为了减少或避免事故发生,不少企业采取了多种安全措施,对冲床进行了各种改革。采用单板机(也称微电脑)作为控制中心,使送料与冲压按预定要求协调动作,就是一种较先进的办法。一、工作原理 CJ-801型单板机控制冲床,把整机分成两大部分。第一大部分是机械传动部分,在冲床上增加 Punch is a widely used type of machine tool with poor safety. In order to reduce or avoid accidents, many companies have taken a variety of security measures, the punch carried out a variety of reforms. The use of single-board machine (also known as micro-computer) as a control center, feeding and pressing the scheduled requirements of coordinated action, is a more advanced approach. First, the working principle CJ-801 single-board machine control punch, the machine is divided into two parts. The first part is the mechanical transmission part, increased in the punch
