Abstract

PURPOSE: To enable and facilitate forging of a tube plate by making a blank into thick disk form and making a hollow and a projection with a press and then forming a peripheral part on the outside of the projection.
CONSTITUTION: A blank 1 formed to a thick disk from an ingot by compression forming is used as a starting blank. After peripheral forming, this is made into the first semimanufactured blank 1' having low cylindrical form. This is placed on a set peripheral mold 2 on a surface plate of a press, and a hollow 4 is formed by thrusting a punch 3 from above. At the same time, the peripheral part is pushed up to form a ring-shaped projection 5 and this is made the second semimanufactured blank 1". This is overturned and fitted to a lower die 7 which has a ring-shaped groove 6 on the upper face to which the projection 5 fits in. Then, it is pressed from above to reduce the thickness of the disk 8 and, at the same time, pushing it out in the radial direction to form the peripheral part 9 in the outer periphery of the projection 5. In this way, a completed forged material 1" is obtained.
