应力法剪切下料是精密下料方法同裂纹技术的应力断料原理相结合的产物。通过建立夹紧剪切过程中被剪棒料的应力状态方程,分析了被剪棒料同剪刃及夹紧块之间的挤压应力分布,通过挤压应力的分布形式探讨了合理的剪刃形状,进而通过实验研究确定了适宜的剪刃几何参数,为应力法剪切的应用提供了理论依据和适宜剪刃。
The shear stressing method is a combination of the precision blanking method and the stress-blanking principle of the crack technology. Through the establishment of the stress state equation of the sheared bar during the shearing process, the distribution of the compressive stress between the sheared bar and the shearing edge and the clamping block is analyzed. The reasonable shear distribution The shape of the blade is determined, and the appropriate geometrical parameters of the blade are determined through the experimental study, which provides the theoretical basis and suitable cutting edge for the application of the shear method.
