In this paper general calculating method is given to calculate the forces of various punching dies with different inclined edge and comparisons are made among the different forces of various punching dies.

给出了计算各种斜刃结构冲模的冲裁力的一般方法，并比较了各种刃口结构冲模的冲裁力大小，为生产中选取斜刃参数提供参考。

The design method of faceplate oblique edge blanking die, die structure, punch structure and matrix structure were introduced in detail.

详细介绍了面板斜刃冲裁模的设计方法和模具结构及冲裁凸凹模结构。

Using bevelled punch and step punch in blanking die, carried on the rational distribution to blanking force, reduced the blanking force well which the press equipment need, and the question of insufficient press equipment pressure was solved.

在冲裁模中结合使用斜刃凸模和阶梯凸模,对冲裁力进行合理分配,很好地降低了冲压设备所需的冲裁力,解决冲压设备压力不足的问题。

The text that analyses 400 mm oblique cutting machine's mechanics parameter,according to themachinery quality of recent products of Lingang proofs that the equipment can match with flattening machine and the other two crosscut machines in this factory,it means that in can cut 25 mm plain steel plate and low alloy plate,so that it enlarges the production's restriction from 6 mm～20 mm to 6 mm～25 mm.

根据临钢中板厂现有产品的机械性能 ,对该厂 4 0 0 0 mm斜刃剪力能参数进行了分析 ,论证了该设备可以与该厂的矫直机及其它两台剪切机相匹配 ,即可剪切δ 2 5 mm普碳板和低合金板 ,从而把该厂的产品规格范围由 6 mm～ 2 0 mm扩大到 6 mm～ 2 5 mm。

Conclusions from the experiments indicate that a plate with given thickness and the influence of the inclination α of die with inclination edge the blanking power made are of major significance, and the die gap between the punch and the die comes second.

分析了中厚板冲裁时影响冲裁力的几个主要因素 ,并由实验确定了对于给定厚度的板料 ,斜刃口模具倾角α对冲裁力的影响是主要的 ,凸、凹模间隙次之。
