Abstract (en)
[origin: CN104107870A] The invention refers to a spring winding machine with an adjustable cutting device. A spring winding machine that manufactures helical springs (200) by spring winding includes a feed device that feeds wire (115) to a shaping device (120), wherein the shaping device has a winding tool (122,124) and a pitch die (130); a cutting device that separates a finished helical spring from the wire after termination of shaping, wherein the cutting device (152) has a cutting tool which, by a drive system, can be moved along a predefinable closed trajectory; a control device that controls the feed device, the shaping device and the cutting device on the basis of an NC control program; and a programmable trajectory-setting system that sets the shape and/or position of the trajectory to be passed through by the cutting tool, wherein a trajectory which is mirror-symmetrical with respect to a plane of symmetry and has a predefinable ratio of height to width.
