在一九七六年第5期上论述了锻压自动机凸轮轮廓设计的几个主要问题。但双滚子双凸轮机构的回程凸轮轮廓设计问题以及机构中的补偿问题还未涉及。本文准备就这两个问题加以讨论。这篇是前篇的续篇,是上次讨论问题的继续,故有些公式及叙述,请参阅前篇。 In the fifth issue in 1976, several major problems in cam contour design of forging automata were discussed. However, the design of the return cam profile of the double-roller double-cam mechanism and the compensation problem in the mechanism have not been covered yet. This article is prepared to discuss these two issues. This is the continuation of the previous article, is the continuation of the previous discussion, so some formulas and narrative, see the first part.
