Title:
ROLLER HEMMING DEVICE AND ROLLER HEMMING METHOD
Document Type and Number:
WIPO Patent Application WO/2006/137467
Kind Code:
A1
Abstract:
A roller (48) starts to bend a standing flange (65) in the initial state of a roller hemming processing. A first plate material (63) is fitted to a receiving face (15) by the strong holding action of the roller (48) and an auxiliary roller (51) at a contact point (70) between the roller (48) and the standing flange (65). On the other hand, the receiving face (15) tends to be separated from the first plate material (63) by the reaction thereof at those portions other than the contact point (70). Since slider blocks (22) and (22) are movable along rails (21) and (21) on a receiving mold (10), the receiving mold (10) is rotated clockwise about the contact point (70) (as shown in the figure). Since the receiving mold (10) is rotated about the contact point (70), the adhesiveness of the first plate material to the receiving face at the contact point (70) can be assured. As a result, the hemming processing free from wrinkles, waving, and deformation to provide excellent shape can be achieved.
