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 WebOct 11, 2005 · The condition of a blanked edge can be tailored by adjusting the punch and die clearance; shaving the defective area of the blanked edge; designing an appropriate contact profile of the punch and die; and understanding the mechanical properties and microstructure of the sheet metal to select a suitable material.

WebFeb 18, 2024 · The maximum edge crack strain (ECS) can be achieved with a blanking clearance range as of 10~13.1% thickness and under flat blade. Based on the observations of the sheared surface damage and flanging fracture morphology, the mechanism of edge cracking during the flanging forming is revealed. WebOct 10, 2006 · Cutting Basics. Cutting metal requires great force. For example, it takes approximately 78,000 lbs. of pressure to cut a 10-in.-diameter blank from 0.100-in.-thick mild steel. Consequently, the punch, die, and press must absorb overwhelming shock. Overshocking the press and die components usually is what causes them to fail … WebJan 1, 2024 · The present work describes a methodology using the finite element method and neural network simulation in order to predict the optimum punch-die clearance … new online betting sites 2022
