壳体的侧孔冲模,常采用悬臂式凹模。若在不同方位上具有多个孔,只能靠变换定位经多次冲我完成。如果孔位的精度较高,需一次冲裁完成,则总是置凹模于壳体内腔,借助斜楔,在水平方向上使凸模从外向内冲裁。 本厂产品零件中有一筒形外壳(如图1),孔位的精度较高,且要求冲孔毛刺向外(因内腔要与其它零件相配合),若采用前述形式,必须增加去毛刺工艺,加工起来也很不方便。现改用图2形式,效果甚好,简 Shell side hole die, often used cantilever die. If you have multiple holes in different directions, can only rely on the transformation of positioning me to be completed several times. If the accuracy of the hole is high, to be completed once the blanking, the cavity is always set to die cavity, with the wedge, the punch in the horizontal direction from the outside to the inside punching. Our product parts have a cylindrical shell (Figure 1), the hole of high precision, and requires punching burr outward (due to cavity to match with other parts), if the above form, you must increase the deburring Technology, processing is also very inconvenient. Now switched to Figure 2 form, the effect is very good, Jane
