[0034] A plurality of steel pipes are placed on the top of the two swing plates 30, and the L-shaped plate 23 can limit the steel pipes. When the steel pipes need to be unloaded, the electric telescopic rod 24 is started, the electric telescopic rod 24 retracts, and the swing plate 30 swings, and the steel pipes fall into the bottom of the inner cavity of the elastic V-shaped plate 19. The limit plate 33 is pulled by an external device, and the limit plate 33 drives the elastic plate 29 to stretch. The limit plate 33 is aligned with the steel pipe, so as to transport the steel pipe. When it is necessary to adjust the position of the elastic V-shaped plate 19 in coordination with the swing tube 2, the motor 12 drives the elastic V-shaped plate 19 to move through the movable plate 17, the connecting ring 18, and the connecting column 20, thereby improving the flexibility of the device.

[0035] Working principle: When the device starts working, the operator places multiple steel pipes on the top of the two swing plates 30 in the inner cavity of the elastic V-shaped plate 19 through external equipment, so as to achieve the function of storing multiple steel pipes. The L-shaped plate 23 cooperates with the spring 36 to limit the steel pipes. When the steel pipes need to be unloaded, the operator starts the electric telescopic rod 24 through an external power supply. The electric telescopic rod 24 drives the support plate 31 to swing by connecting the U-shaped block 32. At the same time, the electric telescopic rod 24 itself will swing inside the limiting U-shaped block 26 through the swing block 25. The swing plate 30 loses the support of the support plate 31, and the swing plate 30 swings through the hinge. The steel pipes on the top of the two swing plates 30 will fall into the bottom of the inner cavity of the elastic V-shaped plate 19 in turn. At this time, the operator The elastic plate 29 can be pulled by manpower or external equipment, and the elastic plate 29 drives the limit plate 33 to move through the limit rod 35. Then the elastic plate 29 is released, and the limit plate 33 will move forward. The limit plate 33 drives the adjacent steel pipe to move forward, and the front end of the steel pipe will enter the swing tube 2. When the steel pipe enters the swing tube 2, the steel pipe will contact the polishing paper 48, and the polishing paper 48 will polish the surface of the steel pipe. The front end of the steel pipe will enter the cold rolling mill body 4 through the thrust of the elastic plate 29 and the limit plate 33. If continuous transportation is required, when most of the previous steel pipe enters the cold rolling mill body 4, another steel pipe falls to the back side of the previous steel pipe, and the elastic plate 29 is pulled again. The elastic plate 29 drives the limit plate 33 to move forward. Another steel pipe moves, and the other steel pipe will drive the previous steel pipe to move to the front side, so that the previous steel pipe can completely enter the cold rolling mill body 4 for subsequent operations. If the working direction of the adjustment device is adjusted, the operator pulls the limit plate 38 through an external device, and the limit plate 38 drives the swing tube 2 to swing through the rope 37, and the swing tube 2 will gradually change from a horizontal state to a vertical state. At the same time, the motor 12 is started through an external power supply, and the motor 12 drives the transmission rod 13 to rotate, and the transmission rod 13 drives the connecting plate 16 to rotate, and the connecting plate 16 drives the movable plate 17 to rotate, and the movable plate 17 drives the connecting ring 18 to rotate, and the connecting ring 18 drives the elastic V-shaped plate 19 to move through the connecting column 20, and the elastic V-shaped plate 19 drives the movable block 22 to move through the connecting rod 21, and the movable block 22 will move at the movable groove inside the U-shaped frame 3. When the elastic V-shaped plate 19 moves to the front side of the device, the front end of the swing tube 2 will swing to the rear side, and then the limit plate 33 is rotated. The limit plate 33 drives the elastic plate 29 to rotate through the limit rod 35, and the elastic plate 29 drives the movable plate 28 to rotate, and the limit plate 33 is moved to the front side of the elastic V-shaped plate 19. Then the operator pushes the cold rolling mill body 4 to move. The cold rolling mill body 4 drives the fixed column 9, the slider 10 and the inclined rod 11 to move through the U-shaped frame 5, and moves the slider 10 to the annular groove at the top of the ring 8, and pushes the cold rolling mill body 4 to the top of the horizontal plate 6 at the rear side of the device, thereby changing the processing direction of the device.If the sanding paper 48 needs to be replaced, the operator can directly tear off the sanding paper 48. If the double-sided adhesive tape 47 is torn off together with the sanding paper 48, a new double-sided adhesive tape 47 can be attached to one end of the fixed L-shaped rod 46 to install the new sanding paper 48.
