Abstract

PURPOSE: To produce a plurality of hinges through one face-pressing forging by applying face-pressing forging to the partial striplike face area over a width direction of a flat plate material from its front and back to cause material movement, extrusion-molding the bulged parts for working shaft cylinder and blaking these away.
CONSTITUTION: Right and left plate parts of a flat plate material 10 are grasped by means of two sets of clamping upper dies 12, 12' and clamping lower dies 13, 13', and the material is subjected to repetitive face-pressing forging from the top and bottom sides by means of the punches 14 disposed between the dies. This causes material movement from the face-pressing forged area P1 into the extruded die parts 12b, 13b, whereby two sets of bulged parts 11b for working shaft cylinders are extrusion-molded in the end part face areas P2 of the leaf plates 11a contacting right and left. When these are blanked away, two sheets of hinge blank materials having the bulged parts 11b for working shaft cylinders at the end parts of the leaf plates 11a are obtained. Shaft insertion through-holes are pierced in the bulged parts 11b for working shaft cylinders of these hinge blank materials, whereby the leaf-plate-shape hinges are obtained.
