Abstract

PURPOSE: To provide sufficient strength to mounting boss parts having difference of surface level parts close to plate thickness and easily form the same with good accuracy by forming approximately semispherical projections to part of a plate material drawing the projecting top parts to a recessed shape in the opposite direction then forming the side walls of the recesses by forging.
CONSTITUTION: At the time of forming ring-shaped mounting boss parts to a plate material of a drive plate or the like for fluid torque converters, a disc-shaped blank material W made of a sheet steel of predetermined thickness cut of the outside diameter to a final shape is put into a forming device and approximately semispherical projections are formed in the central part of the material W. Then, the material W is charged between the male die and female die 21 and 22 of other forming device 20, and a recessed part W2 a circumferential ring-shaped wall part W3 and an oblique circumferential wall W4 around this are formed by using upper, lower punches 23, 24. Further, the material W is charged between the male, female dies 31, 32 of a forming device 30, and the recessed part W2, walls W3, W4 are finally formed by using upper, lower punches 33, 34 of suitable shapes. At this time, arrangement is so made that the circumferential wall W4 is forged at angle θ1> angle θ.
