Then, after the workpiece is transferred to the side far away from the polishing device by the rotation of the processing servo motor 3, the tail ends of the tail end convex plates at the two ends of the polished special-shaped pipe workpiece completely shield the optical signal of the second photoelectric switch 20, so that the electromagnet mechanism 12 is triggered to be powered off. And then, the special pipe workpiece continues to rotate to enable the polished special pipe workpiece to automatically slide down when the polished special pipe workpiece is in a downward inclined state below the horizontal level. The device is provided with a stripper plate 29 at one side of the sliding platform. The polished special pipe workpiece automatically slides onto the discharging plate 29, and then slides onto the material containing trolley 31 on the ground from the discharging plate 29.
In conclusion, the three surfaces of the special-shaped pipe fitting are polished by the method, so that time, labor and time are saved, full-automatic mechanical control is realized, the polishing quality is better, and the product reject ratio is greatly reduced.
