在冷冲模设计中,凹模的强度计算,一般分作以下几种类型:①圆型凹模;②装在有方形洞的板上的矩形凹模;③装在有矩形洞的板上的矩形凹模。以下的诺模图是按这三种类型来作的。凹模的强度校核,一般是检查其厚度。因此,下述的应用举例,均为求其厚度,但仍可求其中的任一参数。 In the die design, die strength calculation, generally divided into the following types: ① circular die; ② rectangular die mounted on a plate with a rectangular hole; ③ mounted on a plate with a rectangular hole Rectangular die. The following nomograms are based on these three types. Die intensity check, the general is to check the thickness. Therefore, the following examples of applications are to find the thickness, but you can still ask any one of them.
