Abstract: A hemming machine having a nest adapted to support a part to be hemmed. A hold down is movable between a retracted position in which the hold down is spaced from the part and an extended position in which the part is sandwiched between the hold down and the nest and a guide surface is formed around the periphery of the hold down. A hemming head having a roller hemmer assembly and mounted to and manipulated by a robotic arm. The roller assembly includes a first roller which engages the guide surface during a roller prehemming operation of the part performed by the robotic arm and a second roller which prehems the part.

Abstract: A method for sharp, crisp hemming inner (22) and outer (12) aluminum sheet metal panels in which a flange (10) is formed along an outer edge so that the flange extends from a bend line (14) and lies in a plane generally perpendicular to the plane of the outer panel. This bend line, furthermore, has an outer radius in the range of (1.0 mm+t)>R>t (0.2 mm+t) where t= the thickness of the outer panel. The inner panel is then positioned on the outer panel so that an outer edge (24) of the inner panel is adjacent the bend line. The flange is then bent so that the flange overlies the outer edge of the inner panel while simultaneously compressing the flange in the direction towards the bend line. Thereafter, the flange is compressed against the outer peripheral portion of the inner panel thus completing the hem. The present invention thus achieves a sharp radius bend on the outer edge of the panel with a layer radius bend on the inner panel as well as a class "A" surface on the outer panel adjacent the hem which is free of recoil or other distortion.

Abstract translation: 一种用于锋利，酥脆折边的内（22）和外（12）铝金属板的方法，其中沿着外边缘形成有凸缘（10），使得凸缘从弯曲线（14）延伸并位于平面 一般垂直于外板的平面。 此外，该弯曲线具有在（1.0mm + t）> R> t（0.2mm + t）范围内的外半径，其中t =外板的厚度。 然后将内板定位在外板上，使得内板的外边缘（24）与弯曲线相邻。 然后将凸缘弯曲，使得凸缘覆盖在内板的外边缘上，同时沿着朝向弯曲线的方向压缩凸缘。 此后，凸缘被压靠在内板的外周部上，从而完成下摆。 因此，本发明实现了在面板的外边缘上具有在内板上的层半径弯曲的尖锐的半径弯曲以及邻近下摆的外部板上的类“A”表面，其没有反冲或其它变形。
