Workpiece shaping device, has agitating device for partially displacing bulk material in sections during movement of agitating device into chamber containing pressure transmission medium that transforms deformation force to workpiece

摘要

The device (1) has a plunger (4) movable relative to a die (3), and a pressure transmission medium (5) for transferring a deformation force (Fv) to a workpiece (2) for deforming the workpiece. The pressure transmission medium has a free-flowing bulk material (6) i.e. steel ball, that is subjectable to pressure by the plunger. An agitating device (11) i.e. rotational agitator, partially displaces the bulk material in sections during movement of the agitating device into a chamber (7) containing the pressure transmission medium.
