応出来る。 Furthermore, even when rolling a different type of workpiece having a different shape from the workpiece W, the first part is set so that the rolling part of the different type of workpiece is rolled by a pair of rack dies 1a, 1b or 2a, 2b. Position regulating portion 1 on the indexing plate 11 and the second indexing plate 28
By setting the protrusion amount for any one of 2a to 12d (for example, 12d), after the rolling of the workpiece W is completed and a different type of workpiece is attached to the transfer device, the workpiece can be moved in the same manner as above. Positioning is performed, and the position regulating portions 12a to 12d are moved to the indexed position by the indexing mechanism.
This can be done by simply selecting and locking with the locking mechanism.
このように、予め転造しようとするワークの形
