摘要： A hand transport section holds and transports a workplace grip hand for gripping and positioning a workpiece. The hand transport section mounts the workpiece grip hand on a hand mount so as to set the workpiece on a lower die. The hand transport section releases the workpiece grip hand and retracts. The hemming device hems the workpiece with the lower die and an upper die located above the lower die.

摘要： A C-shaped frame is movable in a direction in which the C-shaped frame is adjacent to and away from a workpiece having an outer panel and an inner panel assembled with each other. After the C-shaped frame is advanced and a pre-hemming punch is advanced by a swing cylinder provided at the C-shaped frame, a hemming die is raised by a lifter hydraulic cylinder provided on a lower portion of the C-shaped frame and a flange of the outer panel is provisionally hemmed. Then, after retreat of the pre-hemming punch following lowering of the hemming die, the hemming die is raised again and a final hemming is conducted between the hemming die and the hemming punch.
摘要翻译： C形框架可沿着C形框架相邻并远离具有彼此组装的外板和内板的工件的方向移动。在C形框架前进并且由设置在C形框架上的摆动滚筒推进前折边冲头的同时，通过设置在C形框架的下部的提升液压缸使折边模具升起，外板的凸缘被临时卷边。然后，在折边模具下降之后，经过折边冲头后退，折边模具再次升起，并在折边模头和折边冲头之间进行最后的折边。
