Description

Technical Field

[0001] This utility model belongs to the technical field of seamless steel pipe processing equipment, specifically a seamless steel pipe outer wall cleaning mechanism. Background Technology

[0002] During the production and processing of seamless steel pipes, various impurities may adhere to the outer wall. For example, after the hot rolling process, iron oxide scale may adhere to the surface of the seamless steel pipe. If these impurities are not cleaned in time, they may be pressed into the surface of the seamless steel pipe during subsequent processing steps (such as cold rolling and cold drawing), forming defects such as pits and scratches, thus affecting the dimensional accuracy and surface quality of the seamless steel pipe. Cleaning mechanisms are used to clean the outer wall of seamless steel pipes.

[0003] However, existing seamless steel pipe outer wall cleaning mechanisms are usually only applicable to seamless steel pipes with fixed inner diameters, which has low applicability. When it is necessary to clean the outer wall of seamless steel pipes with different inner diameters, the corresponding cleaning mechanism needs to be replaced, which is troublesome to operate. Summary of the Invention

[0004] The purpose of this utility model is to provide a seamless steel pipe outer wall cleaning mechanism with a reasonable structure, which can clamp and fix seamless steel pipes with different inner diameters, thus improving its applicability.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a seamless steel pipe outer wall cleaning mechanism is provided, including an installation shaft. The outer surface of the installation shaft has four movable grooves. A first lead screw is movably installed on the inner wall of each movable groove. A second gear is fixedly connected to one end of the first lead screw. A movable component is threadedly connected to the outer surface of the first lead screw. A fixing component is fixedly connected to the inner bottom of each movable groove. A rotating arm is movably installed at the end of both the fixing component and the movable component away from the first lead screw. A clamping plate is movably installed at the end of the rotating arm away from the first lead screw. A groove is provided inside the installation shaft. A first motor is fixedly connected to the inner wall of the groove. A first rotating shaft is fixedly connected to the output end of the first motor. A first gear is fixedly connected to the end of the first rotating shaft away from the first motor. The first gear meshes with the second gear.

[0006] Optionally, a worktable is provided below the mounting shaft, a fixing plate is fixedly connected to the upper surface of the worktable, a second motor is fixedly connected to the side wall of the fixing plate, a second rotating shaft is fixedly connected to the output end of the second motor, and the end of the second rotating shaft away from the second motor is fixedly connected to the side wall of the mounting shaft.

[0007] Optionally, a third motor is fixedly connected to the side wall of the workbench, and a second lead screw is fixedly connected to the output end of the third motor. A movable plate is threadedly connected to the outer surface of the second lead screw, and a bearing is movably installed on the side wall of the movable plate near the fixed plate.

[0008] Optionally, a mounting bracket is fixedly connected to the upper surface of the workbench, and a brush plate is fixedly connected to the side wall of the mounting bracket.

[0009] Optionally, a nozzle is fixedly connected to the lower surface of the mounting bracket, and there are multiple nozzles. A pipe is fixedly connected to the upper surface of the mounting bracket, and there are multiple pipes. The pipes are connected to the nozzles.

[0010] Optionally, the upper surface of the workbench is provided with an installation groove, the interior of the installation groove is provided with a filter plate, the lower surface of the workbench is fixedly connected with a sludge storage tank, and the side wall of the sludge storage tank is fixedly connected with a sludge outlet.

[0011] Optionally, the lower surface of the workbench is fixedly connected with four legs.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model includes an installation shaft, a first lead screw, a fixing component, a moving component, a rotating arm, a clamping plate, a first motor, a first rotating shaft, and a first gear. When a seamless steel pipe needs to be fixed, the seamless steel pipe is first placed around the installation shaft. Then, the first motor is controlled to operate, and its output drives the first rotating shaft and the first gear to rotate, which in turn drives the second gear and the first lead screw to rotate. This causes the moving component to move closer to the fixing component, resulting in a deflection of the rotating arm. Consequently, the clamping plate gradually moves away from the installation shaft until its outer surface firmly presses against the inner wall of the seamless steel pipe, thus clamping and fixing the pipe for easy cleaning of its outer wall. This utility model can clamp and fix seamless steel pipes of different inner diameters, improving its applicability.

[0014] This utility model is equipped with an installation shaft, a second motor, a second rotating shaft, a nozzle, a brush plate, a filter plate, and a sludge storage tank. After the seamless steel pipe is clamped and fixed, the second motor works, and the output end of the second motor drives the second rotating shaft and the installation shaft to continuously rotate in both directions, thereby driving the seamless steel pipe to rotate in both directions. At the same time, the nozzle sprays water, which, together with the brush plate, brushes away the impurities attached to the surface of the seamless steel pipe. The mixture of sewage and impurities is filtered through the filter plate, and the sewage enters the sludge storage tank, while the impurities are intercepted by the filter plate, thereby achieving preliminary solid-liquid separation. After the outer wall of the seamless steel pipe is cleaned, the filter plate can be removed for further cleaning. Attached Figure Description

[0027] Reference Figure 1-6 This invention provides a seamless steel pipe outer wall cleaning mechanism. The mechanism includes a mounting shaft 1 with four movable grooves 2 on its outer surface. A first lead screw 3 is movably mounted on the inner wall of each groove 2. A second gear 8 is fixedly connected to one end of the first lead screw 3. A movable component 5 is threaded onto the outer surface of the first lead screw 3. A fixing component 4 is fixedly connected to the bottom of the inner surface of each groove 2. A rotating arm 6 is movably mounted on the end of both the fixing component 4 and the movable component 5 away from the first lead screw 3. A clamping plate 7 is movably mounted on the end of the rotating arm 6 away from the first lead screw 3. When the seamless steel pipe needs to be fixed, the seamless steel pipe is first placed around the mounting shaft 1, and then a first motor 9 is controlled to operate. The output end of the first motor 9 drives... The rotation of the first rotating shaft 10 and the first gear 11 drives the rotation of the second gear 8 and the first lead screw 3, which in turn drives the moving part 5 to move closer to the fixed part 4, causing the rotating arm 6 to deflect. This causes the clamping plate 7 to gradually move away from the mounting shaft 1 until the outer surface of the clamping plate 7 is tightly pressed against the inner wall of the seamless steel pipe, clamping and fixing the seamless steel pipe so that the outer wall of the seamless steel pipe can be cleaned. The mounting shaft 1 has a groove inside, and the inner wall of the groove is fixedly connected to the first motor 9.

A fixing plate 13 is fixedly connected to the upper surface of the worktable 12. A second motor 14 is fixedly connected to the side wall of the fixing plate 13. The second motor 14 is a forward and reverse motor. A second rotating shaft 15 is fixedly connected to the output end of the second motor 14. The end of the second rotating shaft 15 away from the second motor 14 is fixedly connected to the side wall of the mounting shaft 1. A third motor 16 is fixedly connected to the side wall of the worktable 12. A second lead screw 17 is fixedly connected to the output end of the third motor 16. The outer surface of the second lead screw 17 is threaded. The system is connected to a movable plate 18. During operation, the seamless steel pipe is first placed around the mounting shaft 1. Then, the third motor 16 is controlled to operate. The output end of the third motor 16 drives the second lead screw 17 to rotate, thereby moving the movable plate 18. This allows the bearing 19 to enter the seamless steel pipe, providing support for the rotation of the seamless steel pipe. The bearing 19 is movably installed on the side wall of the movable plate 18 near the fixed plate 13. A mounting frame 20 is fixedly connected to the upper surface of the worktable 12. A brush plate 21 is fixedly connected to the side wall of the mounting frame 20. The brush plate 21 works with the nozzle 22 to spray... The water output can remove impurities adhering to the surface of the seamless steel pipe. Multiple nozzles 22 are fixedly connected to the lower surface of the mounting bracket 20. Multiple pipes 23 are fixedly connected to the upper surface of the mounting bracket 20. The pipes 23 are connected to the nozzles 22 and are supplied with water via external water pipes. After clamping and fixing the seamless steel pipe, the second motor 14 operates. The output of the second motor 14 drives the second rotating shaft 15 and the mounting shaft 1 to continuously rotate forward and backward, thereby driving the seamless steel pipe to rotate forward and backward. Simultaneously, the nozzles 22... Water is sprayed, and brush plate 21 is used to remove impurities attached to the surface of the seamless steel pipe. The mixture of sewage and impurities is filtered through filter plate 25 and the sewage enters the sewage storage tank 26, while the impurities are intercepted by filter plate 25, thus achieving preliminary solid-liquid separation. After the outer wall of the seamless steel pipe is cleaned, filter plate 25 can be removed for cleaning.

[0030] In another embodiment of this utility model, please refer to Figures 1 to 6 The lower surface of the workbench 12 is fixedly connected with four legs 28 to support the workbench 12.

[0031] Working principle: When it is necessary to fix the seamless steel pipe, first, the seamless steel pipe is placed around the mounting shaft 1. Then, the first motor 9 is controlled to work. The output end of the first motor 9 drives the first rotating shaft 10 and the first gear 11 to rotate, thereby driving the second gear 8 and the first lead screw 3 to rotate. This causes the moving part 5 to move closer to the fixed part 4, causing the rotating arm 6 to deflect. This causes the clamping plate 7 to gradually move away from the mounting shaft 1 until the mounting shaft 1 is tightly pressed against the inner wall of the seamless steel pipe, thus clamping and fixing the seamless steel pipe. The outer wall of the seamless steel pipe is cleaned; then the second motor 14 works, and the output end of the second motor 14 drives the second rotating shaft 15 and the mounting shaft 1 to continuously rotate forward and backward, thereby driving the seamless steel pipe to rotate forward and backward. At the same time, the nozzle 22 sprays water, which, together with the brush plate 21, brushes away the impurities attached to the surface of the seamless steel pipe. The mixture of sewage and impurities is filtered through the filter plate 25, and the sewage enters the sewage storage tank 26, while the impurities are intercepted by the filter plate 25, thereby achieving the initial separation of solid and liquid. After the outer wall of the seamless steel pipe is cleaned, the filter plate 25 can be removed for cleaning.
