国内外大中型冲模常用的矩形限位器,是用2个螺钉拧在模座上的。这种限位器的工艺过程需经锯料、加热、锻造、铣刨6面、倒角,再钳工划线和钻孔等工序。不仅工序多,而且制造周期长。但把结构改为柱形限位器,只需用一个螺钉紧固在模座上。这样,可直接采用圆棒料来加工,只需车两端面,倒一面角,同时加工出螺钉安装孔来就可以了。全部工序只需一台车床即可完成。
Large and medium-sized medium-sized domestic and international rectangular stopper is screwed in the mold base with 2 screws. The stopper of the process required by the sawing, heating, forging, milling 6 surface, chamfering, and then clamp fitter drilling and other processes. Not only process, but also long manufacturing cycle. However, to change the structure of the cylindrical stopper, only one screw fastened to the mold base. In this way, the bar can be used directly to the processing, just car both ends, down side angle, while the screw holes to work out on it. All processes only need a lathe to complete.
