Claims

[Scope of utility model registration request]

a die receiver having a spherical surface on its outer peripheral surface and disposed within the apparatus main body on the workpiece drawing side of a die that plastically processes the workpiece into a predetermined shape when the workpiece passes through;
a die fixing body for pressing the die from the workpiece insertion side and fixing it to the die receiver; and a spherical seat having a spherical seat on an inner peripheral surface for externally fitting and holding the die receiver. In the die alignment device, a plurality of alignment rods are movably attached to the die receiver and the spherical seat so that the spherical surface of the die receiver and the spherical seat of the spherical seat form opposite spherical corners. and a movable fixing means for fixing the alignment rod at an arbitrary moving position, and a biasing means for urging the alignment rod in a direction in which the spherical surface of the die receiver comes into close contact with the spherical seat of the spherical seat. A die centering device characterized by:
