在铣床上进行切削加工时,常常会遇到被加工的零件无法进行正常装夹。给铣床加装电磁吸盘,就能有效地解决装夹问题。但是电磁吸盘也会给被加工的零件带来一些麻烦。比如被加工零件的剩磁问题,对某些产品,零部件存在剩磁是不允许的。笔者在设计电气控制线路时,专门增加了快速自动退磁线路。该线路结构简单、元件少、安装调试都较方便。电磁吸盘工作时,工件被吸待,开动铣床进行切削加工,加工完毕,吸盘停止工作,同时吸盘和工件自动进行快
In the milling machine for cutting, often encountered in the processing of parts can not be normal folder. Milling machine to install electromagnetic sucker, can effectively solve the problem of clamping. But the electromagnetic chuck will also bring some trouble to the parts being processed. For example, the remaining parts of the processed magnetism problems, for some products, parts of the residual magnetism is not allowed. The author in the design of electrical control circuit, specifically increased the rapid automatic demagnetization circuit. The line structure is simple, less components, installation and commissioning are more convenient. Electromagnetic chuck work, the workpiece is sucked, start milling machine for cutting, processing is completed, sucker stop working, while the suction cup and the workpiece automatically fast
