PURPOSE: A shear drawing apparatus is provided to reduce the abrasion of a shear die by reducing contact pressure between intersection parts and materials. CONSTITUTION: A shear drawing apparatus comprises supply units and a shear die(130). The supply units apply pressing force for shear deformation to materials(2). The shear die comprises a channel in which the materials passing through the supply unit are sheared. The channel comprises an inlet channel(131), an outlet channel, and one or more crossing parts(134,135). The materials from the supply units enter the inlet channel. The materials are discharged by the outlet channel. The channels close to each other are connected to the cross parts at a crossing angle. |
