Feeding device of cold heading forming machine

The utility model relates to the technical field of cold heading forming machines, and discloses a feeding device of a cold heading forming machine, which comprises a cross-shaped base plate, an air cylinder, a circular plate and four supporting rods which are obliquely distributed, wherein four base plates on the cross-shaped base plate are respectively provided with a sliding groove which is vertically and upwards distributed, and a limiting rod which is horizontally arranged is fixed in each sliding groove; and the circular plate is horizontally arranged above the cross-shaped base plate. According to the size of a ring opening of a placed steel wire ring, the air cylinder works to drive the circular plate to ascend and descend through the piston rod, and when the circular plate ascends and descends, the four supporting rods are driven to adjust the angle, so that the storage stability of different steel wire rings is adapted, and when the steel wire rings of different models need to be stored, the operati
