为了适应不同的冲压工艺要求,许多压力机行程的大小是可调节的,通常使用压力机行程与偏心套调整角度对照表通过压力机的调整机构得到不同的压力机行程。本文介绍一种作图法,可快速在已知行程情况下求出偏心套转角,及在已知偏心套转角情况下求出压力机行程。在缺少资料的情况下,这是一种有效的应急措施。

To meet the different requirements of the punching process,the stroke of some presses could be adjusted. The reference list of slide stroke and sleeve position was usually used in practice.Adjusting mechanism of presses might get different slide strokes.The graphic method was introduced.It can quickly get the eccentric sleeve position in a known stroke,and can get the stroke in a known eccentric sleeve position.It is a useful emergency measure without reference.
