Roller hemming processing apparatus and roller hemming processing method

摘要

A panel to be processed is placed on the die face (1a) of the hemming die (1), and pre-mending (preliminary bending) and hemming (main bending) processing are performed on the hemming roller held by the robot . A nest mechanism (6) for positioning the panel is provided on the side wall portion (1b) of the hemming die (1). The nest mechanism (6) supports a movable nest block (8) having a nest claw part (8 b) at the tip thereof on a holder (7), and the nest block (8) ), And is resiliently supported so as to be able to swing (tilt) in the direction of the arrow P 2. Thereby, the interference between the hemming roller and the nest mechanism (6) does not adversely affect the hemming processing quality.
