Abstract
A cyclically operable spring coiling machine includes a pair of feed rolls for intermittently advancing wire longitudinally to a coiling station at an upper portion of a vertical front frame of the machine. A coiling arbor and a coiling tool at the station cooperatively form leading end portions of the wire to a coil spring configuration and an improved cut-off means severs the coiled leading end portions of wire to provide individual coil springs. The improved cut-off means includes a pair of tool holders on opposite sides of the coiling arbor movable toward and away from the arbor and wire coiled thereabout and generally in opposition to each other. The holders are employed selectively depending on the hand of the spring being coiled and are respectively mounted on pivot shafts extending rearwardly through the front frame of the machine and geared together at rear end portions. A continuously rotating horizontal shaft forming a part of the coiling machine drive mechanism has a front end portion projecting through the vertical front frame of the machine. An eccentric on the front end portion of the shaft drives an oscillable arm which in turn has a pivotal connection with a lowermost tool holder through an adjustment means. The adjustment means comprises complementary threaded members operable to adjust the movement of the tool holders and thus to vary throw of a cut-off tool thereon toward and away from the coiling arbor.
