The square workpiece (steel sheet) is placed in the guide hole 241, the rolling driving element 23 drives the rolling pushing plate 22 to move, and the square workpiece is pushed into the circular die cavity 211 along the guide hole 241 and the guide groove 212, so that the square workpiece is rolled into a circular workpiece.
Referring to fig. 4, the shaping mechanism includes a shaping die 31, a pushing rod 32 and a shaping driving element 33, the pushing rod 32 is mounted on the shaping driving element 33, the pushing rod 32 and the shaping die 31 are respectively arranged on two sides of the rounding die 21, the pushing rod 32, the shaping die 31 and the rounding die 21 are coaxial, and the pushing rod 32 can be inserted into a circular die cavity of the rounding die 21 and can move back and forth along the axial direction of the circular die cavity under the driving of the shaping driving element 33. The shaping die 31 has a circular cavity with an inner diameter slightly smaller than the outer diameter of the work piece rolled into a circular ring shape by the rolling mechanism. After the square workpiece is rolled into a circular workpiece through the rolling mechanism, the pushing rod 32 is inserted into the rolling die 21, the circular workpiece is pushed into the shaping die 31 from the rolling die 21, the circular workpiece is extruded by the shaping die 31, the head end and the tail end of the workpiece are combined better, and the circular workpiece is more circular.
Referring to fig. 5 and 6, the chamfering system includes a chamfering die 41, a moving driving element 42, and two chamfering mechanisms including a chamfering frame 51, a rotating shaft 52, a chamfering tool 53, a chamfering driving element 54, and a motor 55. The rotating shaft 52 is mounted on the chamfering frame 51 so as to be rotatable relative to the chamfering frame 51. The motor 55 is mounted on the chamfering frame 51, and drives the rotation shaft 52 to rotate by a belt transmission. A chamfering tool 53 is mounted at one end of the spindle 52. The chamfering frame 51 is movably provided on the base 1, and is moved back and forth relative to the base 1 along the axial direction of the chamfering tool 53 by the drive of the chamfering drive element 54. The two chamfering mechanisms are arranged in mirror image, the two chamfering tools 53 of the two chamfering mechanisms are coaxial and the blade portions are opposed to each other. The chamfering tool 41 is between the two chamfering tools 53, and on the shaping tool 31 side, the axis of the chamfering tool 41, the axis of the chamfering tool 53 and the axis of the shaping tool 31 are on the same horizontal plane. The chamfering die 41 is connected to a push rod 421 of the moving drive element 42, and the chamfering die 41 is movable back and forth between a position coaxial with the shaping die 31 and a position coaxial with the chamfering tool 53 under the drive of the moving drive element 42. The chamfering die 41 has a holding through hole 413, and when the chamfering die 41 is moved to a position coaxial with the shaping die 31 (as shown in fig. 1), the pushing rod 32 pushes the annular workpiece shaped by the shaping mechanism into the holding through hole 413 of the chamfering die 41, and the holding through hole 413 clamps the annular workpiece shaped by the shaping mechanism. Then, the movable driving element 42 pushes the chamfering die 41 to move to a position coaxial with the chamfering tool 53, and the chamfering driving elements 54 of the two chamfering mechanisms push the chamfering frame 51 to move towards the chamfering die 41 until two ends of the annular workpiece are respectively inserted into one chamfering tool 53, and the motor 55 drives the chamfering tool 53 to rotate so as to chamfer the two ends of the annular workpiece simultaneously.
Referring to fig. 5, the chamfering mechanism further includes a positioning plate 43, the positioning plate 43 being provided on one side of the chamfering tool 53.

The left chamfering die 411 and the right chamfering die 412 each have one semicircular groove, which together constitute the chamfering die 41 holding through hole 413. The left chamfering die 411 can move a small amount relative to the right chamfering die 412 under a certain external force. When the left chamfering die 411 is not acted by a certain external force, the clamping through holes 413 can firmly hold the circular workpieces placed in the left chamfering die, and the circular workpieces cannot fall out. When the chamfering die 41 is moved to a position coaxial with the chamfering tool 53, the right chamfering die 412 is blocked by the positioning plate 43, the left chamfering die 411 is pushed by the movement driving member 42 to move a small amount to the right chamfering die 412, and the clamping through hole 413 clamps the annular workpiece placed therein very firmly so that the annular workpiece does not rotate and fall out at the time of chamfering operation. When the chamfering operation is completed, the movable driving member 42 moves toward the rounding mold 31 with the chamfering mold 41, the chamfering mold 41 is no longer subjected to the bidirectional pressure of the movable driving member 42 and the positioning plate 43, the pressing force of the movable driving member 42 against the left chamfering mold 411 disappears, and the left chamfering mold 411 is reset. When the chamfering die 41 is moved to a position coaxial with the shaping die 31, the shaping driving member 33 further pushes the pushing rod 32 forward to push out the finished bearing ring product that has been chamfering in the chamfering die 41.
