近年来,我所广泛采用了插入式凸模结构的导板模,也即凸模浮动的导板模,如图1所示。对原采用的通用模架式结构模具(见图2),进行了彻底的改革。此种模具是在线切割工艺占主导地位的基础上产生发展的,各种零件基本上采用单件平行生产。它的主要特点及一些基本设计原则,笔者以图1所示的“风扇电机定、转子冲孔级进模”为例分述如下。该电机定、转子冲片零件如图3所示。由于插入式凸模结构的导板模最适宜于发展级进模,故将原分别用复合模或简易模先单冲定子孔和转子孔,然后进行落
In recent years, I have widely adopted the guide plate of the plug-in punch structure, that is, the guide plate die of the floating punch, as shown in FIG. 1. The original use of common mold structure mold (see Figure 2), a thorough reform. This kind of mold is the basis of online cutting process to produce development, basically all kinds of parts using a single parallel production. Its main features and some basic design principles, the author shown in Figure 1, “fan motor stator and rotor punching progressive die” as an example described below. The motor stator and rotor blanking parts shown in Figure 3. As the plug-punch structure of the guide die most suitable for the development of progressive die, so the original respectively with a single mold or simple mode single punch first punch hole and rotor hole, and then drop
