Detailed implementation manners
[0031] The following further elaborates on the present application in conjunction with the attached Figures 1-5 for a more detailed description.
[0032] The embodiment of the present application discloses a steel pipe straightening device. As Figure 1 shown, it includes a frame 1. A plurality of first pressure rollers 11 and second pressure rollers 12 are provided on the frame 1. The first pressure rollers 11 and the second pressure rollers 12 are both arranged along the moving direction of the steel pipe. The steel pipe passes between the first pressure rollers 11 and the second pressure rollers 12, and both the first pressure rollers 11 and the second pressure rollers 12 are in contact with the surface of the steel pipe. One end of the frame 1 is provided with a feed hole 13, and the other end is provided with a discharge hole 14. During actual operation, the operator inserts one end of the steel pipe into the feed hole 13, and the first pressure rollers 11 and the second pressure rollers 12 can flatten the steel pipe, and the flattened steel pipe is removed from the discharge hole 14.
[0033] As Figure 1 and 2As shown, the first pressure roller 11 rotates relative to the frame 1. A control assembly 2 for controlling the rotation of the first pressure roller 11 is provided on the frame 1. The control assembly 2 includes a mounting bracket 21, a worm 22, and a first turntable 23. The mounting bracket 21 is rotatably connected to the frame 1, and the first pressure roller 11 rotates relative to the mounting bracket 21. The worm 22 is rotatably connected to the frame 1, and the first turntable 23 is fixedly connected to one end of the worm 22. A connecting block 211 is fixedly connected to the mounting bracket 21, and a groove mating with the worm 22 is formed in the connecting block 211. A mounting bolt 212 is provided on the mounting bracket 21, and a kidney-shaped hole 213 is formed in the mounting bracket 21. The mounting bolt 212 slides within the kidney-shaped hole 213 and is threadedly connected to the frame 1 through the kidney-shaped hole 213. The operator can adjust the angle of the mounting bracket 21 according to the size of the steel pipe, thereby adjusting the angle of the first pressure roller 11. When it is necessary to control the rotation of the mounting bracket 21, the operator can rotate the first turntable 23. The rotation of the first turntable 23 can drive the rotation of the worm 22, the rotation of the worm 22 can drive the movement of the connecting block 211, and the movement of the connecting block 211 can drive the rotation of the mounting bracket 21, thereby realizing the rotation of the first pressure roller 11 to adapt to steel pipes of different sizes. After the mounting bracket 21 rotates to a suitable position, the operator can tighten the mounting bolt 212 so that the mounting bolt 212 rotates to abut against the orifice of the kidney-shaped hole 213. The mounting bolt 212 can limit the mounting bracket 21 to fix the mounting bracket 21 and the frame 1, reducing the possibility of deflection of the mounting bracket 21 and improving the position stability of the first pressure roller 11.
[0034] As Figure 2 , 3As shown in FIGS. 3 and 4, a rotating rod 214 is rotatably connected to the mounting frame 21. The first pressing roller 11 is fixedly sleeved on the rotating rod 214. A first bevel gear 215 is rotatably connected to the mounting frame 21. A second bevel gear 216 is fixedly connected to the rotating rod 214. The first bevel gear 215 and the second bevel gear 216 cooperate with each other. A rotating assembly 3 for controlling the rotation of the first bevel gear 215 is provided on the machine frame 1. The rotating assembly 3 includes a motor 31, a first sprocket 32, a second sprocket 33 and a chain 34. The motor 31 is fixedly installed inside the machine frame 1. The first sprocket 32 is coaxially and fixedly connected to the output shaft of the motor 31. A plurality of second sprockets 33 are provided. The second sprocket 33 is coaxially and fixedly connected to the rotating shaft of the first bevel gear 215. The chain 34 is wound around the first sprocket 32 and the second sprocket 33. During actual operation, after the operator rotates the mounting frame 21 to a suitable position, the chain 34 is wound around the first sprocket 32 and the second sprocket 33, and then the motor 31 is driven. The output shaft of the motor 31 drives the rotation of the first sprocket 32. The first sprocket 32 can drive the rotation of the second sprocket 33 through the chain 34. The rotation of the second sprocket 33 can drive the rotation of the first bevel gear 215. The rotation of the first bevel gear 215 can drive the rotation of the second bevel gear 216. The rotation of the second bevel gear 216 can drive the rotation of the rotating rod 214, thereby driving the rotation of the first pressing roller 11 so that the first pressing roller 11 can stably convey the steel pipe.
[0035] As Figure 5 shown, the second pressing roller 12 and the machine frame 1 slide relative to each other. The second pressing roller 12 moves closer to or away from the first pressing roller 11. A sliding frame 4 slides relative to the machine frame 1. The second pressing roller 12 is rotatably connected to the sliding frame 4. A sliding block 15 is fixedly connected to the machine frame 1. A sliding groove 41 is formed in the sliding frame 4. The sliding block 15 is located in the sliding groove 41 and slides therein. A sliding assembly 5 for controlling the sliding of the sliding frame 4 is provided on the machine frame 1. The sliding assembly 5 includes a fixed seat 51, a screw 52 and a second turntable 53. The fixed seat 51 is fixedly connected to the machine frame 1. The screw 52 is threadedly connected to the fixed seat 51. One end of the screw 52 extends into the fixed seat 51 and is rotatably connected to the sliding frame 4. The second turntable 53 is fixedly connected to the screw 52. The operator can adjust the distance between the second pressing roller 12 and the first pressing roller 11 according to the size of the steel pipe. When it is necessary to move the second pressing roller 12, the operator can rotate the second turntable 53. The rotation of the second turntable 53 can drive the rotation of the screw 52. The rotation of the screw 52 can drive the movement of the sliding frame 4. At this time, the sliding block 15 moves in the sliding groove 41. The sliding block 15 can limit the movement of the sliding frame 4. The movement of the sliding frame 4 can drive the movement of the second pressing roller 12, thereby adjusting the distance between the second pressing roller 12 and the first pressing roller 11 to adapt to steel pipes of different sizes.
[0036] The implementation principle of a steel pipe straightening device according to an embodiment of the present application is as follows:
[0037] The operator adjusts the positions of the first pressure roller 11 and the second pressure roller 12 according to the size of the steel pipe. When adjusting the first pressure roller 11, the operator rotates the first turntable 23, thereby driving the rotation of the worm 22. Through the cooperation of the worm 22 and the connecting block 211, the rotation of the mounting frame 21 is driven, thereby adjusting the angle of the first pressure roller 11. When adjusting the second pressure roller 12, the operator rotates the second turntable 53 to drive the rotation of the screw rod 52. The rotation of the screw rod 52 can drive the movement of the sliding frame 4, thereby driving the movement of the second pressure roller 12. Then, the driving motor 31 is driven to make the output shaft of the motor 31 drive the rotation of the first pressure roller 11. After that, the steel pipe is moved so that one end of the steel pipe extends into the feeding hole 13. The steel pipe can be transported in the frame 1 under the rotation of the first pressure roller 11, and the first pressure roller 11 and the second pressure roller 12 can flatten and straighten the steel pipe. The straightened steel pipe is removed from the frame 1 through the discharging hole 14.
[0038] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
