Abstract

A machine for the production of coil springs (10) each of which is shaped from a piece of wire and has at its free ends end turns (11) which are bent to an approximate U-shape and over lie one another as seen in the direction of the axis of the spring (17), wherein the machine comprises several processing stations (177 to 178, 200) and a spring annealing station (180) in a circular arrangement and furthermore a turntable (181) comprising gripper arms (182 - 185) with gripper claws (187) arranged thereon in a radial direction, wherein starting from a spring winding station (177), a coil spring (10) initially unshaped at the ends is grasped by the gripper claws (187) of a gripper arm (182 - 185) and is fed in timed sequence to several processing stations (177 to 178, 200), as well as to the spring annealing station (180), where the end turns (11) are formed on the coil spring (10), characterized in that after the spring winding station (177) in the direction of rotation, a first bending station (178) for the one end turn (11) and, positioned opposite a second similar bending station (178) for the other end turn (11) are synchronously provided, and the bending stations (178, 178) have a central member (66) formed in a U-shape wherein several bending tools (74, 70, 78), displaceable in radial direction with respect to the central member (66), are provided, with recesses in the central member (66) and the bending tools corresponding to the bending points (5 - 8) on the end turns of the coil spring and furthermore a retainer (23) bears on the outer periphery of the central member (66), and that the spring annealing station (180) is connected after the second bending station (179) in the direction of rotation (Figures 3a, 3b, 4).
