Transverse Wedge Rolling
Transverse Wedge Rolling is a process in which a round billet is inserted between appropriately shaped rolls or flat plates that deform the workpiece as it rotates. These tools incorporate a wedge shaped profile, from which the process takes its name.
There are several versions of Transverse Wedge Rolling:
• If rolls are used, they rotate in the same direction and drive the workpiece. Here either two or three rolls (figure1) can be used.
• If flat tools are used, they move in opposite directions while rotating the workpiece between them.
• A planetary system with a single large work roll and a fixed work segment is possible(figure2), or a concave-tooling segments can also be used.
