摘要：
A die assembly for use with a tool for bending flat metal stock, and including a pair of elongated plate members in the lower die member each having a surface to support a piece of flat metal stock, the plate members being pivotably connected and maintained approximately 180 degrees apart when a bending force is not applied to the metal stock. A surface of an expandable pressure container is positioned in contact with a plate support member, the pressure within the container being controlled in a manner such that the vertical position of the plate support member is fixed such that the plate members assume a selected angular orientation to enable the tool to form the desired bend in the metal stock.
