ABSTRACT:
The invention provides an apparatus for full enclosed die forging having a stationary die, a movable die toward and away from the stationary die and punches which plunge into a work in the closed dies to form tools. After the stationary die in the die housing and the movable die on the ram are closed, the closed pair of dies is moved in a forging direction into the inside of the die housing. In the die housing is equipped an annular engaging member which is movable in the forging direction and shrinkable toward the closed pair of dies in the die housing. The annular engaging member is thrusted into the inside of the die housing along with the closed pair of dies by thrusting means. Shrinking means is provided for shrinking the annular engaging member toward the closed pair of dies in the die housing as the annular engaging member is thrusted into the die housing so that the annular engaging member engages with the closed pair of dies and clamp them tightly.
