在伟大领袖毛主席“独立自主、自力更生”方针的指引下,我们根据我厂的现有条件,结合产品种类多、批量不大的生产情况,对原来的生产工艺进行了改革,制造出六角螺母及305轴承内圈的热压模。长时间生产实践证明,使用这种简易模具能大大节约人力、物力。 305轴承内圈原来是采用胎模锻造的,现用图1所示的模具热压。模具装在60吨土冲床上。当将模具的上、下模换成如图2所示的模具时,就可冲制M12～M24的螺帽。拉杆15由冲床的滑块带动,用于自动顶出工件。坯料压扁与坯料成形工序同时进行。压扁后的坯料放入成形模中进行第一次成形;然后,将坯料翻身,进行第
Under the guidance of Chairman Mao, the great leader, “independent, self-reliant”, we have reformed the original production process according to the existing conditions of our factory and combined with the production of large quantities and small quantities, to manufacture hexagonal nuts and 305 bearing inner ring hot stamping die. Prolonged production practice has proved that using this simple mold can greatly save manpower and material resources. 305 bearing inner ring was originally used forging tire, the mold shown in Figure 1 hot pressing. Mold loaded in 60 tons of soil punch. When the mold, the mold into the die as shown in Figure 2, you can punch M12 ~ M24 nut. Lever 15 driven by the punch slider, used to automatically eject the workpiece. Billet crushing is performed simultaneously with the billet forming process. The flattened blank is placed in a forming die for the first time; then, the blank is turned over,
