由于我厂拉深冷桥工件规格较多,所以采用通用切边模具切边,模具结构如图1所示。 一、模具结构特点及使用范围阳模14与阳模座16、限位销15与阳模座16均为D/d动配合。定向销23是阳模定向用(冲切非旋转体工件是不可缺少的)。阴模13外形与阴模座30相应孔成D/d动配合,并以定向销 As my factory deep drawing cold bridge workpiece specifications, so the use of trimming trimming general-purpose mold, mold structure shown in Figure 1. First, the mold structure and use of the scope of male mold 14 and male mold base 16, 15 and the positive limit stop pin seat 16 are D / d with the dynamic. The orientation pin 23 is for male orientation (punching of non-rotating body work pieces is indispensable). The negative form 13 and the female mold base 30 corresponds to the hole D / d with the dynamic fit, and to the orientation pin
