  • Patent number: 3967487
    Abstract: Automatic apparatus and method for simultaneously forming eyes at each end of a leaf spring blank in which hydraulic clamps clamp each end of a spring blank into a working position, hydraulic knock-downs knock down the ends of the spring blank about gooseneck forms advanced in alignment with and beneath the clamping surfaces of the clamps and partially form the ends of the blank, scarfing knives advance with scrolling dies to cut the extreme ends of the blank to conform to the underside of the gooseneck forms. The scrolling dies are advanced toward the ends of the spring blank to further form the ends of the spring blank to a semicircular form. Sizing pins are advanced through the semicircular form of the spring blank, and the scrolls are further advanced to conform the eyes with the anvil and form the spring to size about the sizing pins. The sizing pins are then removed and the formed blank may be passed to a quenching solution.
