HEMMING METHOD AND HEMMING DEVICE

摘要

A hemming method, wherein a moving mold (18) having a first groove (52) and a second groove (54) is moved by a robot (22) along a direction for performing hemming, and positioned on a production line (14) relative to the wheel arch part (16) of a vehicle (12). The moving mold (18) is mounted on the vehicle (12) by a clamp mechanism (58) and fixedly positioned on the vehicle. A guide roller (32) is rolled in the first groove (52) while being engaged with the first groove, and a flange (17) is tilted by the cone of the tapered roller (38) of a hemming roller (30) moving in conjunction with the guide roller (32). Next, the guide roller (32) is rolled in the second groove (54) while being engaged with the second groove, and the flange (17) is bent by the cylindrical surface of the cylindrical roller (40) of the hemming roller (30). Then, after the hemming is completed, the moving mold (18) is separated from the vehicle (12).
