Title: Machine for Manufacturing Spring Washers
IPC: B21F37/04
Filed: 1968-03-18
Abstract: 1,191,031. Coiling wire. HEIWA HATSUJO K.K. 18 March, 1968 [25 April, 1967], No. 13091/68. Heading B3E. A machine, for making spring washers, comprises a continuous coil forming mechanism and a coil-cutting mechanism, the coil-forming mechanism including a rotatably mounted spindle for winding metallic wire therearound, the spindle including a tapered portion at or adjacent one end, and a feeding member mounted around the spindle, having one face shaped to receive an end of the wire when operatively inserted in the machine, the arrangement of the spindle and feeding member being such, that on rotation of the spindle the wire is coiled around the spindle and fed along the spindle over the tapered portion towards a coil cutting mechanism. The spindle 1 is carried by a shaft 3 to which is secured a driving pulley 2. The shaft 3 runs in ball-bearings in a sleeve 6 which is keyed to the frame F so as to be slidable axially. A spring 9b biases the sleeve to the right in Fig. 1 to hold a cam 9 in contact with a roller 12. Fitted in the sleeve 6 is a feeding member 5, Fig. 6, which has a helical end face S, so that as the spindle rotates a wire drawn on to the spindle is fed along the spindle towards a tapered enlargement "t" at the free end. The coiled wire is expanded slightly as it passes over the enlargement so that the coiled wire is driven in rotation by friction. A slot 6a, 6b formed across the end face of the sleeve 6, tangentially to the spindle facilitates the initial insertion of the wire. The roller 12 is eccentrically mounted on the end face of a rotor 14 which is mounted in the frame G and has fixed to it a driving pulley 18. As the rotor rotates the roller 12 engages the cam surface 9a and causes reciprocation of the sleeve 6. The cutter mechanism is also mounted in the rotor 14 and comprises a cutter blade 16 mounted in a block 11 which is slidable in a diametral groove 17 in the rotor. As the rotor turns the block 11 engages an internal face of a cam 13 fixed eccentrically to the frame G. The cutter blade 16 co-operates with an anvil 15 formed on the end of a spindle 15a fitted in the rotor. As the spindle 1 rotates the coiled wire advances along the spindle and the leading coil is moved over the anvil 15 by the reciprocation of the sleeve 6. The cutter blade 16 operates and as the sleeve 6 retracts the out-off coil falls off the anvil. In a modification, Fig. 7 (not shown), the sleeve has a radially projecting peg which enters a helical groove in the bore of a ring rotatably mounted on the sleeve. Rotation of the ring causes reciprocation of the sleeve and the spindle carried by it. In a second modification, Figs. 8a and 8b, the cutter mechanism rotates continuously and reciprocates axially in the frame G. In a third modification, Fig. 9 (not shown), the coiled wire passes through the hollow centre of a rotor which has spring- loaded guide rollers mounted on its entry face. After passing through the rotor the wire is either reeled up or cut into individual washers.
