发明名称 DIES FOR SHEAR DRAWING
摘要 The present invention is aimed at providing dies for shear drawing, which are capable of continuous drawing and shear deformation at the same time. The invention relates to the dies for shear drawing which comprises a material processing channel where materials are sheared and drawn while passing therethrough, wherein the processing channel comprises an inlet path located in the front and an outlet path located in the rear in consideration of the moving direction of the materials: the inlet and outlet paths are connected to each other for the axes of both paths to cross each other at a certain angle; and the processing channel includes a cross-section decreasing area where the cross-section of the outlet path decreases more than the cross-section of the inlet path to allow the materials to be discharged from the exit of the outlet path filled with the materials. The invention enables continuous shear drawing, wherein the dies are easily filled with the materials during shear drawing, thereby obtaining a constant aspect ratio of the cross-section of the materials over the whole length thereof after shear drawing.
