第十讲冲压工艺编制实例编制顺序: 1 严格审查产品零件名称:固定夹。材料:1C号钢板,厚1.5mm,退火状态。生产数量:大批量。镀锌D.Zn15DC按GB1238—76。编制该零件冷冲压工艺过程卡。如图50所示的弯曲件。①了解产品使用性: 该弯曲件固定夹的作用是固定夹紧一个电器零件。2孔φ6是用于固定在产品金属底板上穿两只螺丝的通孔。由于金属底板上的两只螺丝孔孔距为55±0.15 该固定夹2孔距由此也为55±0.15,意为一致,保证装配。②审查零件工艺性:
Lecture 10 stamping process preparation examples of preparation sequence: A rigorous review of the product part name: clip. Material: 1C steel, 1.5mm thick, annealed. Production quantity: high volume. Galvanized D.Zn15DC according to GB1238-76. Preparation of the parts cold stamping process card. A curved piece as shown in FIG. 50. ① understanding of product use: The role of the bending clip is fixed clamping an electrical parts. 2 holes φ6 is used to fix the product through the metal plate through the hole through the two screws. Since the pitch of the two screw holes on the metal base plate is 55 ± 0.15, the pitch of the two holes of the fixing clamp is thus 55 ± 0.15, which means that the assembly is guaranteed. ② review parts craft:
