由于热处理生产的需要,我分厂为热处理车间生产一批急需的吊环(见图1),数量是200件。以前我们是在加热后锻工使用手锻锤在铁砧上完成的,结果是形状不规则,焊缝位置不确定,影响吊环的质量和使用寿命。后因分厂有一台100kN的液压机,决定设计一套简易的模具,在压力机上完成此项工作,具体操作工艺如 Due to the need of heat treatment production, our factory produces a lot of urgently needed rings for heat treatment workshop (see Figure 1), the quantity is 200 pieces. In the past we were forged after heating forged hammer on the anvil to complete, the result is irregular shape, weld location is uncertain, affecting the quality and life of the rings. After the branch because there is a 100kN hydraulic machine, decided to design a simple mold, the press to complete this work, the specific operating techniques such as
