拉深件展开尺寸的计算相当繁琐。使用施惠章设计的诺模图则能迅速查得结果。比较现已出版的国外拉深件展开尺寸图算表,它具有清晰、易查、精度高等优点。从国内外文献中,未见有拉深件拉深系数、拉深次数和工序间拉深直径的图算表。由施惠章设计的诺模图,还可以反查拉深工序高度,这也大大简化了原来相当繁琐的工序高度计算。它在电子计算机普遍使用的今天,仍具有生命力。该图在南京电子管厂工装设计人员中试用时受到好评,特向大家推存。
Drawing parts to expand the size of the calculation is quite complicated. Promise chart design using the nomogram will be able to quickly check the results. Comparing the published drawing parts of the drawing parts of other countries, it has the advantages of being clear, easy to be inspected and of high precision. From the domestic and foreign literatures, there is no chart of the drawing coefficient of drawing parts, drawing times and drawing diameter between processes. Promise chapter by the design of the nomogram, you can also reverse the depth of the deep process, which also greatly simplifies the original very complicated process height calculation. It is still alive today when computers are commonly used. The figure in the Nanjing tube factory tooling designers in the trial was praised, especially for everyone to push save.
