Abstract
A die for use with a punch for bending flat metal stock and including a body defining a support surface adapted to support a piece of flat metal stock, a cavity disposed in a path of movement of the punch and intersecting and projecting below the support surface, and a stop surface forming a bottom wall of the cavity and having first and second surface portions; and a mounting retained by the body. A first elongated die bar is supported by the mouting for both translational and pivotal movement on a first axis in the cavity on one side of the path of movement; the first die bar defining upper and lower surfaces having a wedge shaped cross-section. A second elongated die bar also is supported by the mounting for both translational and pivotal movement on a second axis in the cavity on an opposite side of the path of movement; the second die bar defining upper and lower surfaces having a wedge shaped cross-section. This combination eliminates scoring during the bending of flat metal stock.
