Abstract:
1. A discharge device for worked material, which is disposed in a press working apparatus for applying a press working to a material through a vertical reciprocating motion of an upper die relative to a lower die and which is operable to discharge a worked material produced resultantly from the press working, said device comprising: a chute adapted to receive the worked material produced resultantly from the press working and to discharge said worked material to the outside of said press working apparatus by making a reciprocating motion within a substantially horizontal plane; and a drive means for driving said chute in response to the vertical reciprocating motion of said upper die, wherein said drive means is adapted to drive said chute such that at a moment of stopping of the chute, a force exerted on the worked material in association with a movement of the chute in a direction of the chute movement is greater than a force exerted on the worked material based on a frictional force between said worked material and said chute in a direction opposite to said direction of the chute movement.
