This allows for relatively rapid change over for the hemming system to hem different components. Further, the lift table of the hemming system includes a lift plate which moves the anvil through a predefined constant vertical stroke, but the start and end positions of that constant stroke length can be changed by inserting and removing a set of spacers from the anvil lift path. When the spacers are in the lift path, the lowered position and the raised position of the anvil are both higher than the corresponding lowered position and raised position when the spacers are removed from the lift path. The beam assemblies on the tool platen assembly include mounting surfaces to which both the preliminary hemming beam and the final hemming beams are mounted, one above the other, and the beam assemblies operate to move the hemming beams between a retracted position and a hemming position. The lift table design, and the beam assemblies, combine to provide relatively fast cycle times for complete hemming operations. | 12-11-2008 |
