[0028] The method of use and working principle of this device are as follows: first, the workpiece to be processed is clamped between the bracket 76 and the two clamping blocks 77, and then the clamping blocks 77 on both sides clamp the workpiece.

After clamping, the hydraulic push rod 89 drives the clamping plate 81 and the guide rail 83 to move upward to separate the workpiece from the clamping block 77 and the bracket 76, and the motor 3 85 drives the threaded rod 84 to rotate, and the slide block slides along one side of the guide rail 83 to move the workpiece out from above the bracket 76 and move it to above the guide frame 21, and then the two clamping plates 81 release the workpiece, and the workpiece falls and is guided by the guide frame 21 and then falls on the conveyor assembly 5; The rotating disk 23 continues to rotate, moving the auxiliary mechanism 7 to the side of the recycling box 3. At this time, the motor 2 71 drives the bevel gear 1 72 to rotate, and the bevel gear 1 72 meshes with the bevel gear 2 73, driving the bevel gear 2 73 and the connecting piece 78 to rotate. At this time, the connecting piece 78 and the fixed plate 74 are flipped over, and the debris remaining in the punching hole on the support plate 75 is poured out, and the debris enters the recycling box 3 for collection, and then the fixed plate 74 is reset, and the rotating disk 23 continues to rotate, and the next workpiece to be processed can be placed on the bracket 76.
