图1所示为冲制圆形零件(中φ24.8_(-0.1)×O.8)的简易落料模结构。 分三部分:第一部分为模座,它将上模座与下模座连成整体,这样可使加工方便,减少装配调整的工作量,由于模架上的凹模孔与导套孔是一次装夹加工的,所以能保证其同轴度的要求。在设计过程中考虑到同一模座的通用性能,为此模座的上下孔采用了D_1公差,便于更换凹模和冲头。第二部分为冲头;它有一个导套和一个凸模(即模柄
Figure 1 shows the punched round parts (φ24.8 _ (- 0.1) × O.8) simple blanking die structure. Divided into three parts: The first part is the mold base, which will be on the mold base and the mold base together into a whole, so that processing can be easy to reduce the workload of assembly adjustment, because the mold cavity and guide holes on the hole is a die Clamping process, so to ensure that the requirements of its coaxiality. In the design process to take into account the common mold base of the common performance, this mold base of the upper and lower holes with D_1 tolerance, easy to replace the die and punch. The second part is a punch; it has a guide sleeve and a punch (ie, die shank
