ばね製造機の自由長調整装置。 A material guide that sends out the wire, a coiling tool that bends the wire that is sent out from the material guide, a pitch tool that adds pitch to the bending, and a length measuring device that measures the free length of the coil spring created from the material guide. In a coil spring manufacturing machine equipped with a servo motor that rotates in response to a signal from the NC control device, and a drive shaft to which rotation is transmitted from the output shaft of the servo motor, the coil spring manufacturing machine is equipped with , a swinging cam fixed to the drive shaft, and an L-shaped lever swinging by the swinging cam,
N
By modifying the known contents of the program input to the C control device, the amount of rocking of the rocking cam is partially changed using the modified signal, and the pitch tool is controlled so that the coil spring is always in the optimum state. A free length adjustment device for a coil spring manufacturing machine, which is characterized by adjusting the free length.
