最近看到“锻压技术”1978.№4刊载的“关于双动复合模及其新系列双动油压机的设想”一文,认为作者提供的参考资料是可取的。在此谈几点看法与作者商讨。 1.“新系列”(对该文的简称,以下同)提到其双动油压机的结构“与一般拉延用的双动油压机的区别在于两个滑块呈上下两层布置,而且下滑块的压力大于上滑块的压力”。因而被作者称之为“新系列双动油压机”。其实,这种上下滑块的布置型式早在六十年代初我厂就设计制造过这种结构的板冲压油压机。资料[1]中是这样介绍的:“……拉深滑块在下,而压边滑块在上,”的平行滑块式结构。对于
Recently saw the “Forging Technology” 1978. № 4 “on the double-action compound model and its new series double-action hydraulic press,” article, that the reference materials provided by the author is desirable. Discuss here with the author to discuss. 1. The “new series” (short for the text, the same below) mentions the structure of its double-action hydraulic press. “The difference between the” new series “and the double-action hydraulic press for general drawing is that the two slides are arranged in two layers, The pressure of the block is greater than the pressure of the upper slider ”. Therefore, the author calls it “a new series of double-acting hydraulic press.” In fact, this type of layout of the upper and lower slider as early as the early 1960s, I designed and manufactured this structure plate stamping hydraulic press. The data [1] is introduced in this way: “... draw the slider in the next, while the blank holder in the slider,” the parallel slider structure. for
