Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe manufacturing technology, specifically a pushing device for seamless steel pipe manufacturing. Background Technology

[0002] Seamless steel pipe is a long strip of steel with a hollow cross-section and no seams around its perimeter. Its production process is relatively complex, and the general process includes billet preparation, heating, piercing, rolling, reheating of the rough pipe, sizing (or reduction), heat treatment, straightening, cutting off the ends, inspection (non-destructive, physical and chemical, bench tests), packaging and warehousing, etc.

[0003] In the production process of seamless steel pipes, the pushing device is a crucial component. It is responsible for pushing the heated steel billet into the piercing mill for piercing, thus forming the initial shape of the seamless steel pipe. However, existing pushing devices for seamless steel pipe manufacturing often use multiple sets of cylinders or electric push rods working together to position the steel billet. However, cylinders or electric push rods cannot achieve perfect synchronization, leading to inaccurate positioning of the steel billet and affecting the piercing accuracy. Therefore, we propose a pushing device for seamless steel pipe manufacturing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pushing device for seamless steel pipe manufacturing. By rotating a conical toothed ring on a fixed ring, the conical toothed ring drives the driven conical gears in three sets of limiting components to rotate, thereby ensuring that the three sets of limiting frames and limiting wheels move synchronously to position the steel billet. The two sets of positioning mechanisms further improve the stability of the steel billet positioning. This design greatly improves the positioning accuracy and solves the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pushing device for manufacturing seamless steel pipes includes a sliding rail, on which a mounting base is slidably mounted. Two sets of positioning mechanisms and an auxiliary rotating mechanism are mounted on the mounting base. Each positioning mechanism includes a ring frame fixedly mounted on the mounting base. A fixing ring is fixedly mounted inside the ring frame. Three sets of limiting components are mounted on the fixing ring. A conical toothed ring is rotatably mounted on the fixing ring. Each limiting component includes a hollow column fixed to the fixing ring. An internally threaded column is rotatably mounted on the hollow column. A driven conical gear is fixedly fitted onto the internally threaded column, meshing with the conical toothed ring. A threaded rod is threadedly connected to the internally threaded column, and a limiting frame is fixedly connected to the bottom of the threaded rod.

[0007] Preferably, the limiting component further includes a limiting frame, on which a limiting post is slidably installed, the limiting post being fixedly connected to a threaded rod, and a limiting wheel is rotatably installed on the limiting frame, with a steel billet disposed between the three sets of limiting wheels.

[0008] Preferably, a fixing plate is fixedly connected to the fixing ring, a drive motor is fixedly connected to the fixing plate, and a drive bevel gear is fixedly mounted on the drive shaft of the drive motor, the drive bevel gear meshing with the bevel gear ring.

[0009] Preferably, the auxiliary rotation mechanism includes a fixed frame, an auxiliary frame hinged to the fixed frame, a first rotating rod and a second rotating rod rotatably mounted on the auxiliary frame, two sets of auxiliary rotating wheels fixedly mounted on the second rotating rod, an auxiliary plate fixedly mounted on the mounting base, an electric push rod hinged to the auxiliary plate, and the top end of the output shaft of the electric push rod hinged to the auxiliary frame.

[0010] Preferably, the auxiliary rotation mechanism further includes an auxiliary motor, which is fixedly mounted on the auxiliary frame by a limiting plate. The drive shaft of the auxiliary motor is fixedly connected to the first rotating rod. Both the first and second rotating rods are fixedly fitted with pulleys, and a belt is fixedly fitted between the two sets of pulleys.

[0011] Preferably, a material feeding frame is fixedly installed on the mounting base. Beneficial effects

[0012] This invention provides a pushing device for manufacturing seamless steel pipes. Compared with the prior art, it has the following advantages:

[0013] This pusher device for manufacturing seamless steel pipes rotates and installs a conical toothed ring on a fixed ring. The conical toothed ring drives the driven conical gears in three sets of limiting components to rotate, thereby ensuring that the three sets of limiting frames and limiting wheels move synchronously to position the steel billet. The two sets of positioning mechanisms further improve the stability of the steel billet positioning. This design greatly improves the positioning accuracy.

[0014] This is a pushing device for manufacturing seamless steel pipes. By designing an auxiliary rotation mechanism, an electric push rod can press two sets of auxiliary rotating wheels tightly onto the steel billet, thereby allowing the auxiliary rotating wheels to drive the steel billet to rotate, thus reducing the difficulty of piercing.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-8This utility model provides a technical solution: a pushing device for manufacturing seamless steel pipes, including a sliding rail 1, a mounting base 2 slidably mounted on the sliding rail 1, two sets of positioning mechanisms 5 and an auxiliary rotating mechanism 6 mounted on the mounting base 2, the positioning mechanism 5 including a ring frame 7, the ring frame 7 being fixedly mounted on the mounting base 2, a fixing ring 8 being fixedly mounted inside the ring frame 7, three sets of limiting components 9 being mounted on the fixing ring 8, a conical toothed ring 10 being rotatably mounted on the fixing ring 8, the limiting component 9 including a hollow column 15, the hollow column 15 being fixed on the fixing ring 8, an internally threaded column 14 being rotatably mounted on the hollow column 15, and a driven conical gear 16 being fixedly fitted on the internally threaded column 14. Gear 16 meshes with conical gear ring 10. A threaded rod 13 is threaded onto the internal threaded post 14, and a limit frame 17 is fixedly connected to the bottom of the threaded rod 13. The limit assembly 9 also includes a limit frame 11, on which a limit post 12 is slidably mounted. The limit post 12 is fixedly connected to the threaded rod 13. Limit wheels 18 are rotatably mounted on the limit frame 17, and a steel billet 4 is positioned between the three sets of limit wheels 18. A fixed plate 19 is fixedly connected to the fixed ring 8, and a drive motor 20 is fixedly connected to the fixed plate 19. A drive bevel gear 21 is fixedly mounted on the drive shaft of the drive motor 20, and the drive bevel gear 21 meshes with the conical gear ring 10. A feeding frame 3 is fixedly mounted on the mounting base 2.

[0026] In use, the steel billet 4 in the feeding frame 3 is pushed into the space between the two sets of positioning mechanisms 5. Then, the drive motor 20 is started. The drive shaft of the drive motor 20 drives the active bevel gear 21 to rotate. Under the restriction of the fixed ring 8, the active bevel gear 21 drives the bevel gear ring 10 to rotate. Then, the three sets of driven bevel gears 16 start to rotate synchronously. Under the restriction of the hollow column 15, the driven bevel gear 16 drives the internal thread column 14 to rotate. Then, under the restriction of the limit frame 11 and the limit column 12, the threaded rod 13 starts to move. The threaded rod 13 drives the limit frame 17 and the limit wheel 18 to move until the three sets of limit wheels 18 reach the steel billet 4. This design greatly improves the positioning accuracy of the steel billet 4.

[0027] The auxiliary rotation mechanism 6 includes a fixed frame 24, an auxiliary frame 25 hinged to the fixed frame 24, a first rotating rod 27 and a second rotating rod 30 rotatably mounted on the auxiliary frame 25, two sets of auxiliary rotating wheels 28 fixedly mounted on the second rotating rod 30, an auxiliary plate 22 fixedly mounted on the mounting base 2, an electric push rod 23 hinged to the auxiliary plate 22, and the top end of the output shaft of the electric push rod 23 hinged to the auxiliary frame 25; the auxiliary rotation mechanism 6 also includes an auxiliary motor 26, which is fixedly mounted on the auxiliary frame 25 by a limiting plate, the transmission shaft of the auxiliary motor 26 is fixedly sleeved with the first rotating rod 27, pulleys 31 are fixedly mounted on both the first rotating rod 27 and the second rotating rod 30, and a belt 29 is fixedly mounted between the two sets of pulleys 31;

[0028] In use, after the steel billet 4 is positioned, the electric push rod 23 is started. With the cooperation of the fixed frame 24 and the auxiliary frame 25, the two sets of auxiliary rotating wheels 28 are brought against the steel billet 4. Then the auxiliary motor 26 is started. The transmission shaft of the auxiliary motor 26 drives the first rotating rod 27 to rotate. With the cooperation between the belt 29 and the two sets of pulleys 31, the two sets of auxiliary rotating wheels 28 begin to drive the steel billet 4 to rotate, thereby reducing the difficulty of piercing the steel billet 4.

[0029] Working principle: When in use, the steel billet 4 in the feeding frame 3 is pushed into the space between the two sets of positioning mechanisms 5. Then, the drive motor 20 is started. The drive shaft of the drive motor 20 drives the active bevel gear 21 to rotate. Under the restriction of the fixed ring 8, the active bevel gear 21 drives the bevel gear ring 10 to rotate. Then, the three sets of driven bevel gears 16 start to rotate synchronously. Under the restriction of the hollow column 15, the driven bevel gear 16 drives the internal thread column 14 to rotate. Then, under the restriction of the limit frame 11 and the limit column 12, the threaded rod 13 starts to move. The threaded rod 13 drives the limit frame 17 and the limit wheel 18 to move until the three sets of limit wheels 18 reach the steel billet 4. This design greatly improves the positioning accuracy of the steel billet 4.

[0030] Once the steel billet 4 is positioned, the electric push rod 23 is activated. With the cooperation of the fixed frame 24 and the auxiliary frame 25, the two sets of auxiliary rotating wheels 28 are brought abutted against the steel billet 4. Then, the auxiliary motor 26 is activated. The drive shaft of the auxiliary motor 26 drives the first rotating rod 27 to rotate. With the cooperation between the belt 29 and the two sets of pulleys 31, the two sets of auxiliary rotating wheels 28 begin to drive the steel billet 4 to rotate, thereby reducing the difficulty of piercing the steel billet 4. Afterwards, with the cooperation of the sliding rail 1 and the mounting base 2, the mounting base 2 drives the steel billet 4 to move towards the ejector pin.

[0031] This design not only improves the accuracy of positioning the steel billet 4, but also reduces the difficulty of piercing the steel billet 4.
