Abstract

A die post assembly that supports a metal panel in a position to allow an implement such as a roller or die steel to flange, pre-hem or hem an edge of the panel. A die post support surface is disposed on a panel support element and an edge member of the assembly. The die post support surface is shaped to support the panel and includes a bearing surface that supports an overlying portion of the panel against deformation as the marginal edge portion of the panel is bent in a flanging or hemming operation. The edge member includes the bearing surface and is supported on the panel support element. The edge member comprises a material more durable than the material of the panel support element. This material is sufficiently durable to allow the edge member to support a series of metal panels over a large number of hemming or flanging cycles without flowing or otherwise deforming due to heat and pressures typically generated in such operations.
