HEMMING HEAD DEVICE AND METHOD |
摘要 |
A hemming head device and method for hem forming one or more edges of deformable material. The hemming head device includes dual biasing spring members which provide a resistive force whether the hemming wheel is in a push hemming operation on an exterior joint edge or in a pull hemming operation on an interior joint edge. The device further includes a quick connect device for selectively connecting hemming wheels and other forming devices to the head and a gauge to measure the relative position or resistive force applied on the forming member by the biasing members. A method for hem forming a workpiece using dual biasing spring members is also disclosed. |
