采用图示的冲裁摸下料,可获得尺寸准确和冲裁面光洁的制件。在中心带有出屑圆孔的矩形底板上,用螺钉和定位销固定了一对刃口锋利的,且其外圆带有微小锥度以形成后角的圆盘。固定圆盘的螺钉头顶面开有十字槽,供相应的螺丝刀之用;其上的垫圈外径与厚度,应视坯料尺寸并便于从二圆盘间准确通过而定。冲头由工具钢制造,柄部尺寸按压床联接部分确定,车成即可,工作部分形状由铣
Use the icon blanking touch the next expected to get the size and blanking surface clean and bright parts. On a rectangular base with a circular hole in the center, a pair of sharp edges are fixed with screws and dowels, and the outer circumference is slightly tapered to form a relief angle disk. The top surface of the fixed disc screw head is provided with a cross groove for the corresponding screwdriver; the outer diameter and the thickness of the washer shall depend on the size of the blank and facilitate the accurate passage of the two discs. Punch made of tool steel, handle the size of the connection press the bed to determine the car into the work part of the shape by the milling
