在拉深带凸缘工件6主体形状时,同时在工件的斜面中心内侧,即不影响产品使用的位置,成型一个用于弯边加工的定位凸台7。然后把拉深件放到下道工序弯边模的顶板8上进行弯边加工。弯边凸模11紧固在凸模座12上,上面设置环形凹模3,凹模3随凹模座2同时升降。推板4的外形与凹模3的内腔滑配;导正销5与推板中心通孔滑配,并可沿轴向滑动,依靠
In the process of drawing the main body of the flanged workpiece 6, a positioning boss 7 for the crimping process is formed on the inner side of the center of the bevel of the workpiece, that is, the position which does not affect the use of the product. Then the drawing parts into the next process of bending the top plate 8 for bending process. Flange punch 11 fastened on the punch holder 12, the upper surface of the annular die set 3, the die 3 with the die holder 2 simultaneously lift. The shape of the push plate 4 and the inner cavity of the die 3 sliding fit; guide pin 5 and push plate center through-hole with the slide, and can slide along the axis, rely on
