上海机械1964年10月号刊出“落料模以凹模修凸模計算公式探讨”一文以后,我們收到了一些讀者来信,对本文提出几个问题、其中有的读者认为本文标题与文章內容不符,經我們核对,系誉写差错,应更正为“落料模以凸模修凹模計算公式探讨”。此外,讀者对公式D_凸=(D_工-0.75△-z_小)-0.25△系数的选用、本公式的应用范圍、为什么要以凸腘夹薨寄5忍岢鑫侍?希望我们解釋清楚,限于我們的水平,只能作如下几点说明: (1) 设计人员在設計模具时,必須根据工厂制造水平、设备条件和设计模具的类型来决定是应該修配凸模,还是修
After Shanghai Machinery’s October 1964 issue of the article entitled “Discussion on Calculation Formulas of Blanking Die for Die Blanking Die”, we received some letters from readers and put forward a few questions to this paper, some of whom think that this article title and article content Does not match, after our check, reputation write errors, should be corrected as “blanking die to die repair Die calculation formula.” In addition, the reader of the formula D_ convex = (D_ 工 -0.75 △ -z_ small) -0.25 △ coefficient of choice, the scope of application of this formula, why should be convex 腘 folder 薨 5 tolerance 岢 Xin paternity? I hope we explain clearly, limited to our level, can only make the following points: (1) designers in the design of mold, the factory must be based on the level of production, equipment and mold design to determine the type of mold should be equipped with punch, Or repair
