Abstract

Fine-blanking is a hybrid metal forming process that combines the technologies of stamping and cold extrusion. This article describes the three principal design features of the fine blanking process: the vee-ring, clearance between punch and die, and counterforce imposed by the ejector. It discusses the advantages and disadvantages of edge blanking and materials. The article reviews the classification of fine-blanking dies such as the moving-punch system and the fixed-punch system, and provides information on the mechanical and hydraulic fine-blanking presses.
