Method and apparatus for forming a profile in a wall of a hollow cylindrical work piece |
摘要 |
Hollow cylindrical blanks of tubular stock are transformed into finished work pieces (3) in a single work stroke with a profiling tool (7) equipped with profiling rollers (30) in one tool section (8) and a die matrix (15) in another tool section (6). The two tool sections (6, 8) are coaxially movable relative to each other, for example by a press. Each profiling roller in the one tool section is rotatably mounted in a chamber and all rollers (30) are positioned circularly around a central longitudinal tool axis (34) so that a central plane of each roller extends substantially radially relative to the tool axis. The die matrix (15) in the other tool section (6) is supported on a central mandrel or arbor (14) that also supports the blank. The die matrix (15) has in its outer surface a plurality of grooves (15A) and ridges (15B) that cooperate with grooves and ridges in the profiling rollers.
