In the standard designing procedure of stamping die, the calculation formulas of dimensions of both punch and die plate are derived based on such a principle that for blanking operation to produce the punch with the die plate as the basic part, and for the punching operation to produce the die plate with the punch as the basic part. But in practice, due to the condition and tradition, for both the blanking and punching, the usual way is to produce punch first and then the die plate, or in the...

In the standard designing procedure of stamping die, the calculation formulas of dimensions of both punch and die plate are derived based on such a principle that for blanking operation to produce the punch with the die plate as the basic part, and for the punching operation to produce the die plate with the punch as the basic part. But in practice, due to the condition and tradition, for both the blanking and punching, the usual way is to produce punch first and then the die plate, or in the opposite way, so the conversion between them is needed. In this paper, based on the theoretic formula for standard part and considering three situations which occured after wearing: enlarging, shrinking and unchanging, a practice oriented calculation formulas for dimensions ( A n, B n, C n) are derived by converting the standerd part to the non standard, illustrating analysis, and transforming the formulas. By the derived formulas, the problem is solved that the dimensions calculating has′nt corresponding formnlas when the first producing part is non standard.

在冲裁模设计中 ,冲裁模的凸模、凹模刃口尺寸计算公式是根据落料以凹模为基准件配制凸模 ,冲孔以凸模为基准件配制凹模的原则建立的。但在实际生产中 ,由于条件和习惯的原因 ,部分工厂采用不分落料、冲孔 ,均是先制造凸模 ,再配制凹模 ,或者反之 ,这样就需要进行换算。本文根据基准件理论公式 ,考虑到模具磨损后尺寸变大、变小和不变的三种情况 ,由基准件向非基准件换算 ,通过图解分析、公式变换 ,导出方便、实用的刃口尺寸 (A非 ,B非 ,C非)计算公式 ,解决了当先制件为非基准件时 ,其刃口尺寸计算无理论公式直接套用的问题。

The author ingeniously makes it possible that the four work procedures of extruding hole,trimming,blanking and forward extrusion of hollow workpiece are completed on the same set of die whose construction is not complex. Moreover, the procedures have been successfully carried out on a 400kN punching machine, making the productivity of progressive extruding the aluminum sealed sheet reach each minute 60 pieces. Therefore,the productivity has improved significantly. In addition, the article introduces a new no\|scrap...

The author ingeniously makes it possible that the four work procedures of extruding hole,trimming,blanking and forward extrusion of hollow workpiece are completed on the same set of die whose construction is not complex. Moreover, the procedures have been successfully carried out on a 400kN punching machine, making the productivity of progressive extruding the aluminum sealed sheet reach each minute 60 pieces. Therefore,the productivity has improved significantly. In addition, the article introduces a new no\|scrap bridge technique in blanking operation,which reduces the loss of material and increases the utilization rate of aluminium sealed sheet greatly.

将挤孔———切连皮———落料———空心件正挤压 4种工序巧妙地复合在一套模具上 ,而且模具结构并不复杂 ,成功地在 4 0 0kN冲床上实施了该工艺 ,使空心毛细管铝封片级进挤压工艺生产率达到每分钟 6 0件 ,大幅度提高了生产效率。本文还在落料工序中采用无搭边新技术 ,一改冲裁落料中有搭边的常规模式 ,减少了搭边损耗 ,大大提高了铝板材的利用率。

Based on relation between blanking pressure and materials' mechanical properties,mainly HV hardness and tensile strength of sheet metals,a model of maximum blanking noise emission presented in previous paper was further deduced mathematically,then two new predicting models were obtained.In order to test the predicting models of blanking noise caused during blanking operation,experimental studies have been done with HV hardness and tensile strength of selected sheet steels,sheet aluminum and sheet coppers.Final results show that the established 3 models are correct,among which the predicting method using HV hardness of sheet metals is the most simple and proper method.Consequently,a simple and practicable method is presented to predict maximum blanking noise emission by using sheet metals' mechanical properties.

考虑到板料硬度、强度与冲裁力的关系,对所提出的冲裁最大噪声即冲裁工艺噪声发射峰值的数学模型作了进一步的数学推导,获得了两个新的预报模型;取用几种钢、铝、铜板的维氏硬度及抗拉强度值,对这些模型进行试验研究,结果表明3个模型都是正确的,其中用硬度值预报是最为简便和精确的,为用板料的特征值来预报冲裁工艺噪声提供了一种简便可行的方法。
