Specific embodiments

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1:

[0023] Please refer to Figures 1-4 , the present invention provides a material receiving device for cold rolling of steel pipes, including a base 1. A material receiving groove 4 is opened on one side of the top of the base 1. A rubber pad 6 is fixedly arranged inside the material receiving groove 4. The rubber pad 6 protects the steel pipe and prevents the steel pipe from deforming due to the impact between the steel pipe and the material receiving groove 4. Two moving rods 9 are slidably connected to both the front side and the back side of the base 1. Every two moving rods 9 on one side form a group. One ends of the two groups of moving rods 9 are fixedly connected with limiting plates 10. The two limiting plates 10 move towards the middle to squeeze and limit the steel pipe, so as to align the two ends of the steel pipe for subsequent bundling. One side of the base 1 is fixedly connected with a side plate 2. The top of one side of the side plate 2 is fixedly connected with an inclined plate 3. The bottom end of the inclined plate 3 is fixedly connected with the other side of the top of the base 1. The inclined plate 3 guides the steel pipe to the material receiving groove 4 to prevent the steel pipe from directly falling into the material receiving groove 4 and reducing the impact. Telescopic plates 7 are slidably connected to both the front side and the back side of the inclined plate 3. One side of the telescopic plate 7 is fixedly connected with a baffle 8. The telescopic plate 7 can expand the material receiving range of the inclined plate 3 and can be applicable to steel pipes of more sizes. The baffle 8 prevents the steel pipe from falling from the side during the rolling process and keeps the rolling direction of the steel pipe. A limiting mechanism 5 is arranged on one side of the inclined plate 3;

[0024] A drive groove 11 is provided inside the base 1. Through holes 12 are provided on both sides of the middle of the front of the base 1 and both sides of the middle of the back. The through holes 12 communicate with the drive groove 11. The moving rod 9 is slidably connected inside the through holes 12. The through holes 12 limit the position where the moving rod 9 moves, and thus limit the direction of movement of the limiting plate 10. Both sides inside the drive groove 11 are slidably connected with moving seats 13. One sides of the two moving seats 13 are respectively fixedly connected to one ends of two groups of moving rods 9. When the moving seats 13 move, they drive the moving rods 9 and the limiting plate 10 to move. The middle of the drive groove 11 is rotatably connected with a bidirectional lead screw 14 through a bearing. The outer wall of the bidirectional lead screw 14 is threadedly connected to the middle of the moving seat 13. Under the threaded cooperation of the bidirectional lead screw 14 and the two moving seats 13, the two moving seats 13 move towards each other simultaneously, and thus the limiting plate 10 moves towards the middle simultaneously;

[0025] One end of the bidirectional lead screw 14 penetrates through the front of the base 1 and is fixedly connected with a driven gear 15. The bottom of the front of the base 1 is fixedly connected with a connecting frame 16. The middle of the front of the connecting frame 16 is rotatably connected with a rotating shaft 17 through a bearing. One end of the rotating shaft 17 penetrates through the front of the connecting frame 16 and is fixedly connected with a driving gear 18. The driving gear 18 is meshed and connected with the driven gear 15. Under the meshing cooperation of the driving gear 18 and the driven gear 15, the bidirectional lead screw 14 rotates, changing the driving position of the bidirectional lead screw 14 and preventing the driving of the bidirectional lead screw 14 from interfering with the movement of the limiting plate 10. The front of the connecting frame 16 is fixedly connected with a mounting frame 19. A driving motor 20 is fixedly arranged inside the mounting frame 19. The other end of the rotating shaft 17 is fixedly connected with the transmission shaft of the driving motor 20. Starting the driving motor 20 provides power for the rotating shaft 17 and can automatically adjust the position of the limiting plate 10;

[0026] Specifically, first, pull the telescopic plate 7 according to the length of the steel pipe, which can adjust the material receiving range of the inclined plate 3 according to the length of the steel pipe, so that the steel pipe rolls from the inclined plate 3 into the material receiving groove 4, and steel pipes of different lengths can be received. Then start the driving motor 20 to make the driving gear 18 rotate. Under the meshing cooperation of the driving gear 18 and the driven gear 15, the bidirectional lead screw 14 rotates. Under the threaded cooperation of the bidirectional lead screw 14 and the two moving seats 13, the two moving seats 13 drive the two limiting plates 10 to move towards the middle simultaneously, squeezing and limiting the steel pipe, so as to align the two ends of the steel pipe for subsequent bundling.

[0027] Embodiment 2:

[0028] The limiting mechanism 5 includes two sliding grooves 501, a clamping groove 502 and two connecting grooves 503. The two sliding grooves 501 are respectively opened on the front and back of the inclined plate 3. The telescopic plate 7 is slidably connected inside the sliding groove 501. The sliding groove 501 limits the position where the telescopic plate 7 moves. The two connecting grooves 503 are both opened on one side of the inclined plate 3. The connecting groove 503 communicates with the sliding groove 501. A clamping plate 504 is slidably connected inside the connecting groove 503. The clamping groove 502 is opened on the other side of the telescopic plate 7. There are multiple clamping grooves 502, which are arranged at equal distances on the other side of the telescopic plate 7. The clamping plate 504 is snap-connected with the clamping groove 502. Through the snap connection between the clamping plate 504 and the clamping groove 502, the position of the telescopic plate 7 is limited, preventing the telescopic plate 7 from sliding randomly and avoiding the baffle 8 from moving randomly and affecting the rolling direction of the steel pipe;

[0029] Two fixing frames 505 are fixedly connected to one side of the inclined plate 3. Two springs 506 are fixedly connected to one side of the clamping plate 504. One end of the spring 506 is fixedly connected to the inner wall of one side of the fixing frame 505. Under the elastic force of the spring 506, the clamping plate 504 is pushed towards the clamping groove 502, so that the clamping plate 504 remains snap-connected with the clamping groove 502, and then the telescopic plate 7 is limited. A pull rod 507 is fixedly connected to the middle of one side of the clamping plate 504. The pull rod 507 is slidably connected to the middle of one side of the fixing frame 505. One end of the pull rod 507 penetrates through one side of the fixing frame 505 and is fixedly connected with an anti-disengagement block 508. Pull the anti-disengagement block 508 to drive the pull rod 507 and the clamping plate 504 to move, so that the clamping plate 504 disengages from the clamping groove 502, and then the telescopic plate 7 is disengaged from the limit, facilitating the adjustment of the position of the telescopic plate 7;

[0030] Specifically, first pull the anti-disengagement block 508 to drive the pull rod 507 and the clamping plate 504 to move, pull out the clamping plate 504 from the clamping groove 502, compress the spring 506, so that the telescopic plate 7 is disengaged from the limit. Then adjust the position of the telescopic plate 7 according to the length of the steel pipe, and then release the anti-disengagement block 508. Under the action of the spring 506, the clamping plate 504 is engaged with the clamping groove 502, and the position of the telescopic plate 7 is limited, so as to adjust the position of the telescopic plate 7.

[0031] When in use, first pull the anti-disengagement block 508 to drive the pull rod 507 and the clamping plate 504 to move, pull out the clamping plate 504 from the clamping groove 502, compress the spring 506, so that the telescopic plate 7 is disengaged from the limit. Then adjust the position of the telescopic plate 7 according to the length of the steel pipe, and then release the anti-disengagement block 508. Under the action of the spring 506, the clamping plate 504 moves towards the clamping groove 502, and then the clamping plate 504 is engaged with the clamping groove 502, and the position of the telescopic plate 7 is limited, so as to adjust the position of the telescopic plate 7, so that the feeding range of the inclined plate 3 can be adjusted according to the length of the steel pipe;

[0032] Next, the steel pipe is rolled from the inclined plate 3 into the receiving chute 4. When the receiving chute 4 is filled with steel pipes, the driving motor 20 is started to rotate the rotating shaft 17, driving the driving gear 18 to rotate. Under the meshing cooperation of the driving gear 18 and the driven gear 15, the driven gear 15 and the bidirectional lead screw 14 are rotated. Under the screw-thread fit between the bidirectional lead screw 14 and the two moving seats 13, the two moving seats 13 move linearly, driving the moving rod 9 to move, thereby driving the two limit plates 10 to move towards the middle at the same time, squeezing and limiting the steel pipe, so as to align the two ends of the steel pipe for subsequent bundling.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
