[0023] The first pneumatic cylinder 21 drives the first support plate 23 to move forward and backward, and the second pneumatic cylinder 22 drives the second support plate 24 to move left and right, thereby driving the first pressing roller 25 to reach a designated position to press and bend the stator 100.

After reaching the designated position, the second pneumatic cylinder 22 drives the two second support plates 24 to move toward the direction close to the unprocessed stator 100, thereby driving the first pressing roller 25 to press and bend the stator 100; S4: After the clamping roller group and the first clamping roller 25 complete the bending process on the stator 100, the clamping state of the stator 100 is maintained, and the second bending mechanism 3 and the fourth bending mechanism 5 start to work.
