Description

Technical Field

[0001] This utility model relates to the technical field of cold rolling mills for steel pipes, specifically a cold rolling mill for processing steel pipes. Background Technology

[0002] Cold rolling mills are process equipment used for cold rolling of seamless metal tubes. They feature high material utilization and superior product precision and surface roughness compared to cold-drawn tubes. Cold rolling mills use a two-roll or multi-roll system to plastically deform metals and are suitable for the production of precision tubes made of carbon steel, alloy steel, non-ferrous metals, etc. The processing is carried out at room temperature, and continuous rolling makes the tubes dimensionally accurate and have a smooth surface.

[0003] An investigation revealed that a utility model patent (publication number: CN222695607U) discloses a cold rolling mill for processing seamless stainless steel pipes. The mill includes a work cabinet, a work frame fixedly connected to the right end of the work cabinet, a conveying mechanism inside the work frame, a mandrel rotatably connected inside the work frame, a rolling mill slidably connected to the outside of the mandrel, an installation groove inside the rolling mill, a motor fixedly connected to the right end of the installation groove, a threaded rod fixedly connected to the output end of the motor, a piston threadedly connected to the outside of the threaded rod, an oil spray head fixedly connected to the left end of the rolling mill, and a moving mechanism installed inside the work cabinet. In this utility model, the coordinated use of the motor, oil spray head, and other structures allows for automatic oil spraying onto the mandrel and the outside of the material, enabling precise control of the oil spraying quantity and position, ensuring that each part receives an appropriate amount of lubricating oil, and improving the lubrication effect.

[0004] Although the aforementioned patent promotes the lubrication effect on the outer surface of the steel pipe by spraying lubricating oil, its oil spraying structure adopts a downward addition, which means that only the upper surface of the steel pipe comes into rapid contact with the lubricating oil. This cannot ensure that the bottom of the steel pipe is in full contact with the lubricating oil, thereby reducing the uniformity of lubrication. At the same time, a large amount of oil mixture remains on the surface of the steel pipe after processing, which is not convenient for subsequent transportation.

[0005] Therefore, this utility model provides a cold rolling mill for steel pipe processing to solve the above problems. Utility Model Content

[0006] This utility model provides a cold rolling mill for steel pipe processing, which aims to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cold rolling mill for steel pipe processing, comprising a frame, wherein a processing box is provided at one upper end of the frame, and the processing box contains a cold rolling box, a cleaning box, and a drying box;

The lubricating oil tank, the coolant tank and the cleaning fluid tank are all provided with filter components inside.

[0016] The beneficial effects of this application are as follows:

At the same time, with the addition of a collection cover, excess lubricating oil can be recycled.

[0018] This utility model utilizes a cleaning component with a rotating brush sleeve to clean the outer surface of the steel pipe. Simultaneously, the spraying of cleaning liquid effectively removes residual oil from the pipe surface. A drying fan further dries the cleaned pipe, ensuring its dryness and improving the convenience of subsequent processing and transport. This also prevents oil dripping and improves the quality of the working environment. Attached Figure Description

A spray plate 37 is fixedly connected to one end of the processing box 2; a liquid tank 6 is used for the corresponding liquid supply of the diversion pipe 33, the first liquid supply pipe 35 and the second liquid supply pipe 36; a drying fan 4 and a cleaning component 5 are provided. The drying fan 4 is installed inside the drying box 23 and is used for drying the surface of the steel pipe. The cleaning component 5 is installed inside the cleaning box 22 and is used for cleaning the outer wall of the steel pipe. The steel pipe is conveyed by the frame 1, so that the steel pipe enters the collection hood 31 and the processing box 2 in sequence. When it enters the collection hood 31, the internal oil spray nozzle 32 is used to evenly spray the surface of the steel pipe with lubricating oil, which can improve the lubrication effect of cold rolling of steel pipe.

[0027] Furthermore, the bottom of the interior of the cold rolling box 21, the cleaning box 22, and the drying box 23 are all provided with a flow guide hood 24, and the bottom of the flow guide hood 24 is fixedly connected to a first recovery pipe 25. The bottom of the collection hood 31 is fixedly connected to a second recovery pipe 34, and the other end of the second recovery pipe 34 and the first recovery pipe 25 are both connected to the water inlet of the liquid tank 6. Through the setting of the flow guide hood 24 and the first recovery pipe 25, the liquid inside the corresponding box is recovered and processed, which facilitates its secondary filtration and use.

[0028] Furthermore, the fuel injectors 32 are distributed at a 45-degree angle, and four sets of fuel injectors 32 are evenly arranged around the circumference. The inside of the collection cover 31 and the processing box 2 is filled with steel pipes. The even distribution of fuel injectors 32 around the circumference ensures the uniformity of the lubricating oil coating on the surface of the steel pipe.

[0029] Furthermore, the cleaning component 5 includes a bracket 51, which is fixedly connected to the inner wall of the cleaning box 22.

The brush net sleeve 55 and the collection cover 31 are coaxially distributed. The servo motor 52 drives the first gear 53 to rotate, and the meshing of the second gear 54 drives the brush net sleeve 55 to rotate. The rotation of the brush net sleeve 55 removes oil stains and impurities from the surface of the steel pipe. At the same time, the cleaning liquid is sprayed from the spray plate 37 above, improving the cleaning effect.

[0030] Furthermore, the interior of the liquid tank 6 is sequentially equipped with a lubricating oil tank 61, a coolant tank 62, and a cleaning fluid tank 63.

Filter components are also installed inside the lubricating oil tank 61, the coolant tank 62, and the cleaning fluid tank 63.

[0031] Working principle: First, by starting the corresponding circulating pump outside the liquid tank 6, different liquids are sprayed and supplied. Then, when the device is in use, when the steel pipe enters the collection hood 31, lubricating oil is sprayed evenly. When the steel pipe enters the cold rolling box 21 for cold rolling, the cooling liquid sprayed above helps to cool the steel pipe. Further, when the steel pipe enters the cleaning box 22, the cleaning component 5 is started, and the outer surface of the steel pipe is cleaned by the rotation of the brush mesh sleeve 55. Finally, the residual liquid on the surface of the steel pipe is dried by the air drying fan 4 inside the drying box 23.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
