WebIn the blanking of thin plate materials, this means that this directly affects the blanking clearance. If this gap is made unduly small, it can cause fusing problems. The adhered gap is very frequently determined by the … The blanking deformation process can be roughly categorized into three phases: the elastic deformation phase, the plastic deformation phase, and the fracture phase. The stress state of the plate during this process is depicted in Figure 1. Fig. 1 Stress Analysis of plate during blanking deformation In the figure, 1. FC … See more Based on the analysis of the blanking deformation process outlined above, the cross-section of the blanked parts mainly consists of the collapse angle “R”, the bright zone “B”, the fracture zone, and the burr “h”, and has a … See more This article briefly examines the deformation process of blanking and the structure and factors that influence the section of the blanked part. It also introduces a method for quickly and easily determining the … See more
