Abstract
PURPOSE: To raise the temp. of a metallic plate in a short time, form the same by pressing and improve forming efficiency by rotating and moving upward a recessed die of good heat conduction and pressing the metallic plate to a punch.
CONSTITUTION: A metallic plate material 5 is fixed to jigs 4 by means of set screws 6. Next, a recessed die 2 formed of a sintered body of silicon nitride is moved upward while being rotated at a high speed to abut the material 5 on a hold-down jig 7. Then, the material 5 of small thermal capacity grasped by the rotating die 2 and the jig 7 by pressure receives the frictional heat concentrated by the leading end of small curvature of the die 2 and is raised of its temp. in a short time, by which its malleability is increased. Part of the material 5 pressed by the punch 1 enters the clearance between the punch 1 and the die 2, thereby forming a cylindrical body 11 of a bottomed cylindrical shape.
