Title (EN) COIL SPRING WINDING APPARATUS AND METHOD OF WINDING A COIL SPRING
(FR) APPAREIL D'ENROULEMENT DE RESSORT HÉLICOÏDAL ET PROCÉDÉ D'ENROULEMENT DE RESSORT HÉLICOÏDAL
Abstract:
(EN) A coil spring winding apparatus (1) comprises a stator and a rotor (10) which is supported on the stator so as to be rotatable about a rotation axis (13). The rotation axis (13) extends along a spring axis of a coil spring wound by the coil spring winding apparatus. At least one winding tool (21, 22) is supported on the rotor (10) so as to rotate about the rotation axis (13) of the rotor (10) upon rotation of the rotor (10). The at least one winding tool (21, 22) is configured to bend a wire (8) to form the coil spring upon rotation of the rotor (10). The at least one winding tool (21, 22) is adjustable relative to the rotor (10).
(FR) Un appareil d'enroulement de ressort hélicoïdal (1) comprend un stator et un rotor (10) qui est supporté sur le stator de manière à pouvoir tourner autour d'un axe de rotation (13). L'axe de rotation (13) s'étend le long d'un axe de ressort d'un ressort hélicoïdal enroulé par l'appareil d'enroulement de ressort hélicoïdal. Au moins un outil d'enroulement (21, 22) est supporté sur le rotor (10) de manière à tourner autour de l'axe de rotation (13) du rotor (10) lors de la rotation du rotor (10). Ledit au moins un outil d'enroulement (21, 22) est configuré pour courber un fil (8) pour former le ressort hélicoïdal lors de la rotation du rotor (10). Ledit au moins un outil d'enroulement (21, 22) est réglable par rapport au rotor (10).
