摘要:
针对电能表底座进行了排样设计和多工位连续模设计。采用有搭边、双侧载体的排样设计,翻边前预冲工艺孔,保证翻边工位尺寸。模具选用加强型四导柱钢模架,刚度大,运作平稳;模具采用顺装结构,冲孔废料自漏料孔卸下,成品零件由顶件器顶出模具,保证制件顺利卸料而不变形;采用双侧刃定距,设计了侧刃挡块,保证送料步距和精度;双侧刃对角排布,提高了料尾材料的利用率;采用弹压卸料板卸料,确保制件平整;卸料板上安装4对小导柱与凸模固定板上安装的小导套配合形成精密导向系统,保证并提高冲压精度。生产实践证明,电能表底座连续模满足零件尺寸精度要求和生产批量要求。
The layout design and multi-station progressive die were conducted for the electric energy meter base. Then, the layout with overlaps and double carriers was designed, and the technique hole was punched before flanging to ensure the flanging dimension. Next, the four-pillar steel die set was selected for high rigidity and smooth operation, and the die was taken on forward assembly structure with dropping the piercing wastes from self-leakage hole and ejecting the finished products by the ejector to strip the products smoothly without deformation. Furthermore, the side edge stops were designed with double-sided edge spacing to ensure the feeding step and accuracy, and the double-sided edge diagonal arrangement increased the utilization of material at the end. Finally, the spring stripper unloaded the strip to ensure the flatness of product, and the precise guidance system made of four small guide pillars installed in the spring stripper and the small guide assembled in the punch plate guaranteed the stamping precision. The production proves that the progressive die can produce the electric energy meter base to meet the requirements of dimension precision and production batch of the products.
