When the lateral sliding seat 2 moves to the left, when the lateral sliding seat 2 contacts the original position travel switch 18, it means that the lateral sliding seat 2 has returned to its original position and the rotary drive mechanism 17 stops. During the process of the transverse sliding seat 2 moving to the right, when the transverse sliding seat 2 contacts the in-position stroke switch 19, it means that the transverse sliding seat 2 has moved into position, the rotary drive mechanism 17 stops moving, and the clamping plate 3 starts to clamp the lower flash. If the in-position stroke switch 19 fails and the rotary drive mechanism 17 cannot stop moving in time, the transverse sliding seat 2 continues to move to the right. When the transverse sliding seat 2 contacts the safety position stroke switch 20, the safety position stroke switch 20 will stop the rotary drive mechanism 17, which can avoid damage to personnel or equipment caused by abnormal movement and improve the safety of the equipment during operation.
