如图1所示板类零件的斜角通常用气割或铣刨加工,我厂在批量生产中对于尺寸不十分宽的此类零件改用模具冲制效果良好,既提高了生产率又降低了劳动强度:其模具结构主要依据板条(工件)长度分为三种。1.对于长度在150毫米以下的制件采用图2所示的结构。由于多件对称冲制,加之压料板4与凹模9工作刃口封闭,模具各件受力均匀。冲切时制件被紧紧压住,因而此结
As shown in Figure 1, the bevel angle of plate-type parts is usually cut or milled by gas cutting. Our factory has done a good job in converting such parts of very small size into molds in mass production, which not only improves the productivity but also reduces the labor Strength: The mold structure is mainly based on the slab (workpiece) length is divided into three kinds. 1. For parts under 150 mm in length, use the structure shown in Figure 2. As a result of more symmetrical punching, in addition to the pressure plate 4 and the die 9 working edge closed, the mold parts force evenly. When punching the workpiece is tightly pressed, thus the knot
