Flat metal stock bending die

A die for use with a punch for bending flat metal stock and comprising:

• body means 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 said support surface, and a stop surface forming a bottom wall of said cavity and having first and second surface portions;
• mounting means retained by said body means;
• a first elongated die bar supported by said mounting means for both translational and pivotal movement on a first axis in said cavity on one side of said path of movement;
• said first die bar defining upper and lower surfaces having a wedge shaped cross-section including upper and lower legs defined by, respectively, said upper and lower surfaces;
• said lower surface of said first die bar conforming to said first surface portion and adapted for engagement therewith;
• and wherein said first axis extends longitudinally of said first die bar and is disposed between both said upper and lower surfaces and said support surface and said first surface portion;
• and
• a second elongated die bar supported by said mounting means for both translational and pivotal movement on a second axis in said cavity on an opposite side of said path of movement;
• said second die bar defining upper and lower surfaces of complementary shape and having a wedge shaped cross-section including upper and lower legs defined by, respectively, said upper and lower surfaces of said second die bar;
• said lower surface of said second die bar conforming to said second surface portion and adapted for engagement therewith;
• and wherein said second axis extends longitudinally of said second die bar and is disposed between both said upper and lower surfaces of said second die bar and said support surface and said second surface portion.
