Abstract

PURPOSE:To improve the working efficiency of a coil spring by winding wire rod around a winding shaft, cutting the wire, forming a coil spring having a straight part at the ends and sequentially bending the straight part fitting it to a guide bar. CONSTITUTION:The winding shaft 2 is fixed downward under a vertical rotary main shaft 1 and a stopper piece 5 is mounted. The wire rod 4 sent out of a wire supplier 3 is formed in a coil form putting the wire rod 4 between the winding shaft 2 and the stopper piece 5 and turning the shafts 1, 2. The wire rod 4 is cut by a cutter 6 through an automatic detector and a coil spring 8 having straight parts 7 on both ends is dropped along a guide bar. The spring 8 is supported once by a supporting fixture 11 to form hooks 39 with a hook finishing machine 24 on the straight parts 7 of the spring 8 through an air cylinder 32. Since the formation of the coil spring 8 and that of the hooks 39 are executed continuously, the working efficiency of the product is improved.
