[0014] (3) Beneficial effects

[0015] The utility model provides an extrusion device for seamless steel pipes, which has the following beneficial effects:

[0016] (1) Start the electric push rod on the outer wall of the circular plate. Under the action of the electric push rod, the connecting block is pushed forward and backward. When the connecting block moves, it drives the rack to move back and forth. At this time, the rack is limited in the slide groove by the slide plate to ensure that the rack maintains the same direction during the movement. When the rack moves, it will drive gear 1 to rotate. The rotation of gear 1 causes the rotating column to rotate, and then drives the connecting plate 1 at the other end to rotate. When the connecting plate 1 rotates, it will drive the connecting rod to slide in the arc groove, guiding the connecting rod to gradually move outward. The movement of the connecting rod drives the connecting plate 2 to move outward, and the connecting plate 2 is limited in the slide rail by the slider during the movement to ensure the stability of the movement.

[0017] (2) After the motor is started, it drives the rotating shaft to rotate, and then drives the second gear to rotate. The second gear is meshed with the gear ring. When the second gear rotates, it drives the gear ring to rotate. The rotation of the gear ring will prompt the circular plate and other parts connected to it to rotate as a whole. In this process, the fixed column in the base is limited in the inner groove. On the one hand, it provides a limit for the rotation of the circular plate to ensure the stability and accuracy of the rotation. The fixed column also plays the role of supporting the circular plate and bearing the weight of the circular plate and the upper parts. This matching method solves the problem that the seamless steel pipe in the existing device is difficult to flip quickly during the processing process, improves work efficiency, and enables different surfaces of the seamless steel pipe to be easily processed, which brings great convenience to the production and processing of seamless steel pipes.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] Example 1: A seamless steel pipe extrusion equipment, including a bottom plate 1, a base 2 is fixedly connected to the top of the bottom plate 1, a circular plate 3 is provided inside the base 2, an electric push rod 4 is fixedly connected to the outer wall of the circular plate 3, and the output end of the electric push rod 4 is fixedly connected to a connecting block 5, and a rack 6 is fixedly connected to the top of the connecting block 5, and a slide 7 is fixedly connected to the inner wall of the rack 6. At the same time, a slide groove 8 is opened in the middle of the circular plate 3, and a rotating column 10 is rotatably connected to the inside of the circular plate 3. A gear 9 is fixedly connected to the outer wall of one end of the rotating column 10, and the gear 9 is meshed with the rack 6. The rotating column 10 is also fixedly connected to a connecting plate 12, three arc-shaped grooves 13 are opened inside the connecting plate 12, each arc-shaped groove 13 is slidably connected to a connecting rod 14, and the other end of each connecting rod 14 is fixedly connected to a connecting plate 2 15, and the outer wall of each connecting plate 2 15 is fixedly connected to a splint 17, the slide plate 7 is slidably connected in the slide groove 8, and the outer wall of the circular plate 3 is fixedly connected to three slide rails 11, and the inner wall of each connecting plate 2 15 is fixedly connected to a slider 16, and the slider 16 corresponds to the slide rail 11, and the slider 16 is slidably connected in the slide rail 11.

[0026] The seamless steel pipe is placed over the outer wall of the clamping plate 17. Next, the electric push rod 4 on the outer wall of the circular plate 3 is activated. Under its powerful force, the connecting block 5 moves forward and backward. As the connecting block 5 moves, it also drives the rack 6 back and forth. The rack 6 is restrained within the slide groove 8 by the slide plate 7. This design ensures that the rack 6 maintains a consistent direction during movement. As the rack 6 moves, it drives the gear 1 9 to rotate. The rotation of the gear 1 9 causes the rotating column 10 to rotate, which in turn drives the connecting plate 1 12 at the other end. As the connecting plate 1 12 rotates, it drives the connecting rod 14 to slide within the arcuate groove 13, guiding the connecting rod 14 gradually outward. Simultaneously, the movement of the connecting rod 14 drives the connecting plate 2 15 outward. During its movement, the connecting plate 2 15 is restrained within the slide rail 11 by the slider 16, ensuring stable movement. The movement of the connecting plate 2 15 drives the clamping plate 17 to expand outward. This matching method can clamp and fix seamless steel pipes of different inner diameters, greatly improving work efficiency and providing convenience for the processing and handling of seamless steel pipes.

[0027] Example 2: The difference between this example and Example 1 is that, the top of the base 2 is fixedly connected to a bracket 19, the outer wall of the bracket 19 is fixedly connected to a motor 20, and the output end of the motor 20 is fixedly connected to a rotating shaft 21, and the rotating shaft 21 is rotatably connected to the bracket 19, and the outer wall of the rotating shaft 21 is fixedly connected to a gear 2 22, the outer wall of the circular plate 3 is provided with a gear ring 23, and the gear ring 23 is meshed with the gear 2 22, the base 2 is provided with an annular groove 18, the circular plate 3 is rotatably connected in the annular groove 18, and the base 2 is fixedly connected to a plurality of fixing columns 25 inside. At the same time, an inner groove 24 is opened inside the circular plate 3, and the fixing columns 25 are slidably connected in the inner groove 24. A fixing frame 26 is fixedly connected to the top of the bottom plate 1. A hydraulic cylinder 28 is fixedly connected to the top of the fixing frame 26, and a pressure plate 29 is fixedly connected to the output end of the hydraulic cylinder 28. At the same time, a pair of limiting rods 30 are fixedly connected to the top of the pressure plate 29, and the limiting rods 30 are slidably connected in the fixing frame 26. A workbench 27 is fixedly connected to the top of the bottom plate 1, and the workbench 27 corresponds to the pressure plate 29.

[0028] By activating the hydraulic cylinder 28 on the fixed frame 26, the powerful force of the hydraulic cylinder 28 pushes the pressing plate 29 downward. During its movement, the pressing plate 29 is restrained by a stopper 30, ensuring a stable direction of movement. At this point, the pressing plate 29 cooperates with the workbench 27 to pressurize and form the seamless steel pipe. After the seamless steel pipe is extruded on one side, the motor 20 on the base 2 is activated, driving the rotating shaft 21 and gear 2 22 to rotate. The rotation of gear 2 2 also drives the meshing ring gear 23. The rotation of the ring gear 23 causes the circular plate 3 to rotate as a whole. During rotation, the circular plate 3 is restrained within the annular groove 18. Simultaneously, the fixing column 25 within the base 2 is restrained within the inner groove 24 and also supports the circular plate 3. Through the close cooperation between the above-mentioned components, the seamless steel pipe can be quickly flipped, which greatly improves work efficiency, brings convenience to the processing of seamless steel pipes, and improves the continuity and efficiency of production.

[0029] Working principle: when the staff needs to extrude the seamless steel pipe into the desired shape, the seamless steel pipe is first put on the outer wall of the splint 17, and then the electric push rod 4 on the outer wall of the circular plate 3 is started. Under the action of the electric push rod 4, the connecting block 5 is pushed back and forth. When the connecting block 5 moves, it will drive the rack 6 to move back and forth. At this time, the rack 6 is limited in the slide groove 8 by the slide plate 7, so that the rack 6 maintains the same direction when moving. When the rack 6 moves, it will drive the gear 1 9 to rotate. When the gear 1 9 rotates, it will drive the rotating column 10 to rotate, thereby driving the connecting plate 1 12 at the other end to rotate. When the connecting plate 12 rotates, it will drive the connecting rod 14 to slide in the arc groove 13, thereby guiding the connecting rod 14 to gradually move outward, and at the same time drive the connecting plate 2 15 to move outward. When the connecting plate 2 15 is connected, it will be limited in the slide rail 11 by the slider 16, and the splint 17 is driven outward by the movement of the connecting plate 2 15. The expansion can clamp and fix seamless steel pipes of different inner diameters, thereby improving work efficiency. At this time, by starting the hydraulic cylinder 28 on the fixed frame 26, the pressure plate 29 is pushed down under the action of the hydraulic cylinder 28. When the pressure plate 29 moves, it is limited by the limit rod 30, and the pressure plate 29 cooperates with the workbench 27 to pressurize and form the seamless steel pipe. After the extrusion of one side of the seamless steel pipe is completed, the motor 20 on the base 2 is started, and the rotating shaft 21 and the gear 22 are driven to rotate under the action of the motor 20. When the gear 22 rotates, the meshing gear ring 23 is driven to rotate, and the gear ring 23 is driven to rotate as a whole. The circular plate 3 is limited in the annular groove 18 when rotating. At the same time, the fixed column 25 in the base 2 is limited in the inner groove 24, and also supports the circular plate 3. Through the cooperation between them, the seamless steel pipe can be quickly flipped, thereby improving work efficiency.
