Cent of aluminous gusset plate has punching and plane for the surface two kinds.
铝扣板分为表面有冲孔和平面两种。The surface that wears holes is good to absorb high frequency sound.
冲孔面对高频音有良好的吸引效果。Further, the structural characters, design thought, proceedings required attention and assemble process of this piercing die are introduced.
并介绍了该对冲孔模具的结构特点、设计思路、应注意的问题和装配工艺性。Some rules of processing pre-punched hole setting are summarized through the simulated results of two instances . . .
通过对两个例子模拟结果和板料应力应变的分析，总结出了工艺预冲孔设置的一些规律。The utility model is suitable for the centering of punching, drilling or other machining of flat plates.
本实用新型可以用于平板的冲孔、钻孔及其它机加工的对中。Through to technological correct analysis of the blanking patterns components, has designed a continual blanking punching die blanking .
通过对冲裁图样零件的工艺性的正确分析，设计了一个连续冲裁冲孔落料模。Through analyzing the punching process for the supporting pipe, introduced various processing characteristics.
通过对支撑管零件冲孔工艺进行了分析，介绍了各种加工工艺的特点。It is mainly used for piercing , blanking, bending, stretching etc.
其主要用于是冲孔，落料，弯曲，拉伸等。But this method of shape because parts of dies. the blanking the punching the punch with holes can shorten die life space is too little .
可是采用此方法由于零件外形的落料凹模与孔的冲孔凸模空间太小会缩短模具寿命。
