图1是叉子展开图,其工艺是;切条料、落料、切口、冲孔、打指印、压形。其中切口是关键:下面就将切口自动送料冲模部分的结构特点简要介绍一下。 一、凸、凹模采用拼块结构 切口部分的凸、凹模采用拼块结构,它们分别由二片模片和一片模芯所组成(见图2、图3),组装时,用压板和螺栓紧固组 Figure 1 is a fork diagram, the process is; cut strip, blanking, incision, punching, fingerprinting, pressing. Incision is the key: The following will automatically cut part of the die structure of the characteristics of a brief introduction. First, the convex and concave mold using the cut part of the block structure of the convex, concave mold with a block structure, which are composed of two pieces of a die and a core (Figure 2, Figure 3), assembly, the use of pressure plate and Bolt fastening group
