What is the problem of punching without die in the processing of stamping parts?

As a special form in the processing of stamping parts, die-less punching is the most widely used in wire products. The punching without die in the processing of stamping parts actually uses the energy of the rapid movement of the upper die and the cutting edge of the upper die, and the crosspiece under the wire is welded as the fulcrum of the reaction force to cut the workpiece. In order to adapt to the particularity of the workpiece, the lower plane edge of the upper die has a 3° clearance angle. The cutting edge is forward, flush with the straight face of the ram or beyond. In this process, in most cases, there is no good workpiece clamping or material pressing, so the operator must pay attention to safety. The length of the workpiece in the holding direction should be greater than 200mm, otherwise you should consider using auxiliary tools to hold the workpiece to ensure safe operation. Blanking without die is shown in the figure.
