IMPROVED ANGULAR CHANNEL PROCESSING

摘要

An angular channel processing machine (10) including a die (12) which defines first and second channels (13,15) that intersect at an angle, drive means (11) to drive a workpiece (23) through the first channel (13) in a direction toward the second channel (15). The second channel (15) is defined by a die surface (22) and an outer cylindrical surface (21) of a second channel rotatable roll (14) which are disposed in facing relationship. The angular arrangement of the first and second channels (13,15) is such that the workpiece (23) undergoes shear deformation at the region of intersection between the first and second channels (13,15) through engagement with the outer cylindrical roll surface (21).
