ABSTRACT:
A coil spring manufacturing machine which is controlled by a micro-computer is described. Driving source of the coil spring manufacturing machine is a single motor. The power is divided into two independently controllable operation transmitting systems by a power dividing means. The one operation transmitting system transmits rotation to a mandrel assembly for winding a coil around a mandrel. The other operation transmitting system transmits a pitch movement to the mandrel assembly. Machining tools for the formation of coil spring legs are positioned around the mandrel assembly.
