DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0019] According to Figure 1 , 2, as shown in Figures 3 and 4, this embodiment proposes an automatic blanking device for steel pipe production that can prevent damage, including a bottom plate 1. On one side of the top of the bottom plate 1, a discharge cavity 2 is installed. On the other side of the top of the bottom plate 1, a first discharge rail 3 is installed. On one side of the first discharge rail 3, a second discharge rail 4 is installed. The top surface of the first discharge rail 3 is inclined. The second discharge rail 4 is inclined. On one side of the top of the bottom plate 1, a vertical rod 5 is installed. Above the vertical rod 5, a cross bar 6 is installed. A moving mechanism is arranged inside the cross bar 6, and a lifting mechanism is arranged at the bottom end of the cross bar 6.

[0020] The moving mechanism includes an installation cavity 7, a movable frame 8, a first servo motor 9, a threaded rod 10, a threaded sleeve 11, and a guiding structure. The first servo motor 9 is installed on one side of the cross bar 6. The threaded rod 10 is installed below the inside of the cross bar 6. The output end of the first servo motor 9 is connected to one end of the threaded rod 10. A threaded sleeve 11 is arranged on the outer side wall of the threaded rod 10. The bottom end of the threaded sleeve 11 is installed with the installation cavity 7. A lifting mechanism is arranged inside the installation cavity 7. The bottom end of the installation cavity 7 is installed with a movable frame 8. The movable frame 8 is inclined. The movable frame 8 is arranged inside the second discharge rail 4. The movable frame 8 and the second discharge rail 4 are cross-distributed. During use, start the first servo motor 9 to drive the threaded rod 10 to rotate. Therefore, under the limitation of the guide rod 12 and the guide sleeve 13, use the threaded rod 10 to drive the threaded sleeve 11 to move, and then drive the movable frame 8 to move. At this time, the steel pipe moves with the movable frame 8 to convey the steel pipe, so that the steel pipe is not easily damaged due to collision during blanking, thus greatly improving the practicability of the device during use.

[0021] The guiding structure includes a guide rod 12 and a guide sleeve 13. The guide rod 12 is installed above the inside of the cross bar 6. The guide sleeve 13 is arranged on the outer side wall of the guide rod 12. The bottom end of the guide sleeve 13 is connected to the top end of the threaded sleeve 11. During use, with the mutual cooperation between the guide rod 12 and the guide sleeve 13, the threaded sleeve 11 can be guided during movement, making the movement of the threaded sleeve 11 more stable.

[0022] The lifting mechanism includes a second servo motor 14, a screw rod 15, a screw sleeve 16, a movable cavity 17 and a limiting structure. The second servo motor 14 is installed at the top inside the installation cavity 7. The output end of the second servo motor 14 is equipped with a screw rod 15. The outer side wall of the screw rod 15 is provided with a screw sleeve 16. The outer side wall of the screw sleeve 16 is fixedly installed with a movable cavity 17. The bottom end of the movable cavity 17 extends below the installation cavity 7. The bottom end of the movable cavity 17 is connected to the top end of the movable frame 8. When in use, start the second servo motor 14 to drive the screw rod 15 to rotate, so as to drive the screw sleeve 16 to move. Then, under the limitation of the limiting groove 18 and the limiting block 19, the screw sleeve 16 drives the movable cavity 17 to move upward, and further drives the movable frame 8 to move upward, so that the steel pipe rolls out along the first discharge rail 3 from below the movable frame 8, making the discharging of the steel pipe more convenient and efficient, thus greatly improving the working efficiency of the device during use.

[0023] The limiting structure includes a limiting groove 18 and a limiting block 19. The limiting groove 18 is opened inside the installation cavity 7. The limiting block 19 is arranged inside the limiting groove 18. One end of the limiting block 19 is connected to the outer side of the movable cavity 17. The cross-section of the limiting groove 18 is larger than that of the limiting block 19. A sliding structure is formed between the limiting groove 18 and the limiting block 19. There are two limiting grooves 18 arranged inside the installation cavity 7, and the two limiting grooves 18 are symmetrically distributed about the central axis of the installation cavity 7. When in use, by the mutual cooperation between the limiting groove 18 and the limiting block 19, the movement of the movable cavity 17 can be limited during movement, making the movement of the movable cavity 17 more stable.

[0024] Working principle: The steel pipe rolls from above the discharge cavity 2 between the second discharge rail 4 and the movable frame 8. At this time, start the first servo motor 9 to drive the threaded rod 10 to rotate. Then, under the limitation of the guide rod 12 and the guide sleeve 13, the threaded rod 10 drives the threaded sleeve 11 to move, and further drives the movable frame 8 to move. At this time, the steel pipe moves along with the movable frame 8. When the steel pipe contacts the first discharge rail 3, start the second servo motor 14 to drive the screw rod 15 to rotate, so as to drive the screw sleeve 16 to move. Then, under the limitation of the limiting groove 18 and the limiting block 19, the screw sleeve 16 drives the movable cavity 17 to move upward, and further drives the movable frame 8 to move upward, so that the steel pipe rolls out along the first discharge rail 3 from below the movable frame 8. Therefore, the steel pipe is not easily damaged due to collision during blanking. Then start the second servo motor 14 to reverse it, drive the movable frame 8 to move downward, and start the first servo motor 9 to reverse it to drive the movable frame 8 to return to its original position.
