Abstract
A flexible wedge for use under the die of a press to compensate for deflection of the die when force is exerted against it, the wedge being elongated and tapering across its width and having graded flexibility along its length with the portions nearer the ends of the wedge being more flexible in order for the wedge to deflect as a uniformly load beam when a concentrated force is applied at its center to position it under a die.
Claims14
A device to compensate for deflection of a beam to support an elongated die comprising:
- a. a elongated wedge tapering across its width to provide a thick edge and a thin edge,
- b. means providing an inherently graded flexibility along the length of the wedge, said means providing greater flexibility toward the ends of the wedge,
- c. a wedge supporting surface between said beam and said die,
- d. a restraint engaged with each end of said wedge, said restraint positioned to limit the movement of said wedge between the beam and the die, and
- e. means for exerting force horizontally against the thick edge of said wedge and toward the thin edge of said wedge, said force being applied intermediate the restrained ends of said wedge.
