ABSTRACT:
An accessory for a bending brake is secured to the brake only by the clamping force of the brake jaws. A pressing member is rotatably affixed to the base plate which is clamped between the jaws when in operation. A pressing member is attached to the base plate by hinge joints and a linkage, including slotted links which permit the metal sheet to be forcibly pressed against and rolled over the surface of a curved die, ensuring a smooth and even curve surface in the resulting workpiece. The die form is affixed to the front edge of the base plate. The base plates may be interchanged to include different diameter die forms for varying the radius of the executed bend. The location of the die at the front edge of the base plate permits the formation of accurate, smooth curves in sheet metal workpieces in angles of 90-degrees or greater.
