ABSTRACT:
A die module is constructed for an extrusion die which provides for the adjustment of the concentricity of the exit configuration by allowing relative movement of the die within the extrusion die assembly. The die is mounted on a die holder through a pair of mounting rings which fit into a recess in the die body. The rings are constructed with interface surfaces having a curvature with a center upstream. The interface surfaces form a seat within which the die holder is contained with mating surfaces engaging the interface surfaces to allow pivot motion about the center of curvature of the interface surfaces. The engaging surfaces are in the shape of a partial hemisphere to simulate a universal motion. Adjustment bolts are located in the extrusion die assembly downstream of the interface. Bolts, which secure the rings to the die holder, are constructed to provide a fixed spatial relation of the engaging surfaces.
