Abstract

PURPOSE: To perform the die forging similar to that of vertical and horizontal presses through one vertical press operation by performing the forging by upper and lower dies in the initial period of the stroke by a free-forging vertical press and using the remaining stroke for horizontal press.
CONSTITUTION: The forging work is inserted into the specified position of a lower die 22. With valves 17, 17' being held closed, a cross head 1 is lowered and the forging work is die-forged vertically between an upper die 6 and lower die 22. Next, the rams 19, 19' of horizontal press cylinders 7, 7' are operated to advance the mounted core metals 30, 30' just before they contact the forging material. At the same time, the valves 17, 17' are opened. Hence, pressure is generated in the liquid pressure cylinder 4 and by this pressure, the rams 19, 19' are advanced by way of cylinders 14, 14', 7, 7', whereby the forging work is die-forged horizontally. Thence, the valves 17, 17' are closed and the rams 19, 19' are retreated and the forging work is taken out by letting the cross head 1 ascend.
