一、零件简介。(图1所示) 拨簧是一般机箱后墙板安装固定的,快换螺钉的弹性元件,其材料为65Mn或60Sl_2Mn的弹簧钢皮,厚度为0.5mm。该零件要求在不同部位、不同方向成形,其形状比较复杂。采用级进模一次成形其零件展开如图2所示,排样如图3所示。 二、模具特点简介。 1.该模具采用弹压卸料,双侧刃控制步 First, the parts profile. (Figure 1) Dialing spring is a general installation of the rear wall of the chassis fixed, quick-change elastic screws, the material is 65Mn or 60Sl_2Mn spring steel, a thickness of 0.5mm. The parts require different parts, different directions forming, its shape is more complicated. The use of progressive die forming a part of its expansion shown in Figure 2, the layout shown in Figure 3. Second, mold features profile. 1. The mold using elastic discharge, bilateral blade control step
