The international automobile manufacturing industry between the petitive incentives, vehicle development cycle shortens ceaselessly, ceaseless emerge in large numbers of new type, flexible and reconfigurable body production line technology for the manufacturing of small quantities of many varieties and the development ofa new mode of production, shorten the development cycle, isone of the key to enhance petitiveness of products. Wrapping for different workpiece on the work program make the corresponding change to adapt to different workpieces with different characteristics, processing of parts can be smoothly along the contour of the workpiece for movement to rolling hemming, compared with the existing sewing equipment, including high degree of flexible. This paper intends to adopt the stainless steel edge into a wheel hub inner wall, followed by the use of package machine stainless steel edge flanging and wheel pressing, in order to prevent the stainless steel side since the wheels fall off, which is beautiful decorative purposes ( wheel black coating, stainless steel edge similar plating effect, which at present is very popular abroad ).
