中文摘要：“套锻”是一种较为经济实用的锻造方式。结合实例探讨了套锻的可行性，并采用闭式（无飞边）锻造方式，通过模拟软件分析了从锻造成形到冲切分离的全部工艺过程。分析认为，对于部分锻件及标准件采取“套锻”的方式是可行且经济的。
英文摘要： Overlap forging process is an economical and practical forging method. The feasibility of the overlap forging process in closed-die forging method was analyzed, and the whole process for forging step and separation step was analyzed. From these analysis, it is shown that for some forgings and some parts, the overlap forging is feasible and economical.
