我厂制作的两用挡板式冲床安全装置结构简单、制作方便、易于维修、造价低廉、容易操作、可靠安全。其工作原理如下(见图1、图2): 一、手动 将开关K3搬向手动位置,该动作适用于单个零件的冲孔、压弯、压平、切断等作业。此时,脚踏开关K2失去作用。将要加工的零件放在模具上,用 I plant baffled punch press security device structure is simple, easy production, easy maintenance, low cost, easy to operate, reliable and safe. The working principle is as follows (see Figure 1, Figure 2): First, manually move the switch K3 to the manual position, the action is suitable for a single part punching, bending, flattening, cutting and other operations. At this point, the foot switch K2 has no effect. Will be processed parts on the mold, with
