(1) fixing a main mold:
firstly, moving the main mold to a main mold clamping device (25), manually compressing an elastic support rod (31) to contract the elastic support rod (31), and sleeving the main mold on the outer side of the contracted elastic support rod (31);
secondly, the elastic support rod (31) is loosened, the elastic support rod (31) is naturally stretched, and a soft rubber sleeve (32) at the end part compresses the inner wall of the main mold;
(2) fixing the core roller:
firstly, forming a limiting hole at the bottom end of the core roller, and moving the core roller to the position of a core roller supporting mechanism (5);
starting a hydraulic cylinder (11), extending the whole length of a fixed cylinder (14), a middle-connected movable string pipe (15) and a top sleeve (18), and directly inserting the fixed cylinder, the middle-connected movable string pipe and the top sleeve into a limiting hole at the bottom end of a core roller;
(3) core roller straightening:
firstly, the integral length of a fixed cylinder (14), a middle connecting movable string pipe (15) and a top sleeve (18) is adjusted to stabilize the center of gravity of the core roller;
secondly, starting a working switch of the air machine (19), inflating the air machine (19) into the air bag (21) through a pipeline until the air bag (21) expands to abut against the inner wall of the limiting hole of the core roller, correcting the core roller to be in an upright state, and enabling the core roller to be tightly contacted with the core roller correcting device (10);
(4) processing a bearing forging:
firstly, by means of the meshing connection between the clamping teeth (3) and the gear (9), the position of the core roller supporting mechanism (5) is moved along the ring groove (2) until the core roller supporting mechanism (5) is moved to a proper position;
secondly, sleeving a bearing workpiece to the outer side of the main mold, starting a rotating motor in a steering control disc (6) on the core roller supporting mechanism (5), and rotating the core roller to be tightly attached to the workpiece;
starting a motor connected with the main die turntable (26), rotating the main die turntable (26) to drive the bearing workpiece to rotate, and starting forging processing by high friction between the bearing workpiece and the core roller;
starting a motor connected with the grinding turntable (22), rotating the grinding turntable (22), enabling the rotation direction of the grinding turntable (22) to be opposite to the rotation direction of the main mold turntable (26), enabling two end surfaces of the bearing workpiece to be in direct contact with the grinding ring (23), and grinding by the grinding ring (23).
