[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.
[0029] Combination Figure 1 The utility model discloses a CNC ring rolling machine for forging processing, comprising a base 8, a hydraulic cylinder 11 is fixedly connected to the left side of the top of the base 8, the hydraulic cylinder 11 has a simple structure and reliable operation, high output force, and can well support heavy machinery. The output end of the hydraulic cylinder 11 is fixedly connected to a hydraulic rod 12, and the hydraulic cylinder 11 is fed with oil through an oil inlet and an oil outlet, and the oil is discharged to push the piston to move, thereby driving the hydraulic rod 12 to move back and forth upward and downward. One end of the hydraulic rod 12 is fixedly connected to a first cylinder 3. The output end of the first cylinder 3 is fixedly connected to a telescopic rod 2. One end of the telescopic rod 2 is fixedly connected to a first motor 1. The output end of the first motor 1 is fixedly connected to a rotating rod 5. When the first motor 1 works, the output end drives the rotating rod 5 to rotate, thereby rolling the forged ring 15.
[0030] Combination Figure 1 and Figure 2, a third motor 10 is fixedly connected to the middle position of the top of the base 8. A turntable 16 is fixedly connected to the output end of the third motor 10. When the third motor 10 is working, the output end drives the turntable 16 to rotate, thereby driving the forging ring 15 to rotate, and the forging ring 15 is evenly rolled to ensure that the thickness of the forging ring 15 after rolling is uniform. A base 14 is fixedly connected to one side of the third motor 10. The front and rear sides of the base 14 are rotatably connected to the mechanical arm 13, which performs a clamping work to fix the forging to avoid the position deviation of the forging ring, causing the forging ring to deform and cause losses. A fourth motor 17 is fixedly connected to one end of the mechanical arm 13. A metal roller 20 is fixedly connected to the output end of the fourth motor 17. When the fourth motor 17 is working, the output end drives the metal roller 20 to rotate, and the rotation is in the opposite direction and the same speed as the forging ring 15, while limiting the forging ring 15, it can also ensure that the forging ring 15 reaches the target thickness. A forging ring 15 is set on the top of the turntable 16. The right side of the base 14 is partially extended and located below the mechanical arm 13. After the forged ring 15 is rolled to a certain extent, the inner diameter becomes larger, which can support one side of the forged ring 15 to prevent the forged ring 15 from tilting and affecting the final rolling result. The mechanical arms 13 are rotatably connected, and one end of the mechanical arm 13 is fixedly connected to a steering gear 21. The steering gear 21 adjusts the shape of the mechanical arm 13 and changes the position of the metal roller 20 by rotating the output end to adapt to the diameter change of the forged ring 15 during the rolling process for positioning.
[0031] Combination Figure 1 and Figure 3 , a second cylinder 6 is fixedly connected to the right side of the top of the base 8. A T-bar 9 is fixedly connected to the output end of the second cylinder 6. The upper and lower ends of the T-bar 9 are rotatably connected with a connecting rod 18, and the connecting rod 18 connects the T-bar 9 and the fifth motor 19. The fifth motor 19 is fixedly connected to one end of the connecting rod 18. The output end of the fifth motor 19 is fixedly connected to a metal cone 7. When the motor is working, the output end drives the metal cone 7 to rotate, and the rotation direction of the metal cone 7 is opposite to that of the forging ring 15. There are two metal cones 7, and the metal cones 7 are respectively located above and below the forging ring 15. The metal cones 7 are located on the upper and lower sides of the forging ring 15, which can not only limit the position of the forging ring 15, but also limit the height change of the forging ring 15 during the rolling process. The upper and lower ends of the T-bar 9 are fixedly connected with the second motor 4, and the output end of the second motor 4 is fixedly connected to one end of the connecting rod 18. When the second motor 4 works, the output end drives the connecting rod 18 to rotate slightly, and the position of the connecting rod 18 is changed to adjust the distance between the metal cones 7, so as to change the height of the forging ring 15.
[0032] Working principle: First, use the tool to put the forged ring 15 on the turntable 16, the second cylinder 6 starts, pushing the T-bar 9 to move to the left, and the second motor 4 starts to adjust the position and distance of the metal cone 7. The hydraulic cylinder 11 and the first cylinder 3 start to operate to adjust the position of the first motor 1 to ensure that the rotating rod 5 is within the inner circle of the forged ring 15. At the same time, the steering engine 21 works to change the shape of the mechanical arm 13 to ensure that the metal roller 20 contacts the forged ring 15. The fifth motor 19, the fourth motor 17, the third motor 10, and the first motor 1 start at the same time to roll the forged ring 15. During the working process, the first cylinder 3 continuously adjusts the position of the first motor 1, and the second cylinder 6 also continuously changes the position of the T-bar 9. After the work is completed, all motors stop working, the hydraulic cylinder 11 raises the hydraulic rod 12, the second cylinder 6 moves the T-bar 9 to the right, the mechanical arm 13 opens, and the forged ring 15 is removed by the tool.
