Abstract

See full text

An apparatus and method for upsetting an end of a hollow workpiece to increase the wall thickness of that end is taught. A mandrel is inserted into the workpiece within a clamp which holds the workpiece. A die is urged into contact with the end of the workpiece to compress the end, decreasing its length and increasing the wall thickness of the end while the mandrel and clamp prevent deformation of the workpiece held in the clamp.
