Description

Technical Field

[0001] The present application relates to the field of steel pipe processing equipment, and in particular to a cooling device for seamless steel pipe processing. Background Art

[0002] At present, bearing steel pipe is a special steel pipe used to manufacture bearings, which has high hardness, strength and wear resistance. Bearing steel pipe is usually used to manufacture various types of bearings, such as rolling bearings, sliding bearings, etc., and is widely used in mechanical equipment, automobiles, aerospace and other fields. Its manufacturing process includes material selection, heat treatment, precision machining and other links to ensure the service life and performance of the bearing.

[0003] Annealing of steel pipe is a heat treatment process that improves the structure and performance of the steel pipe by heating the steel pipe to a certain temperature and then controlling the cooling rate. Annealing can reduce residual stress, improve machinability and plasticity, improve mechanical properties, etc. Spheroidizing annealing is a common heat treatment method in metal processing, usually used to adjust the grain structure of metal materials and improve their plasticity and toughness. During the spheroidizing annealing process, the metal material will be heated to a certain temperature, then kept warm for an appropriate period of time, and finally the grain structure will be changed by controlling the cooling rate, thereby achieving recrystallization and refinement of the grains and forming a more uniform spherical grain structure. This treatment method can effectively improve the processing performance and mechanical properties of metal materials, and is often used to improve the plasticity and toughness of materials and reduce brittleness. Common spheroidizing annealing cooling methods include: natural cooling, oil cooling, and water cooling.

[0005] When cooling the steel pipe, the above device can only cool the outer wall of the steel pipe, but cannot cool the inside of the steel pipe, resulting in a large temperature difference between the inside and outside of the steel pipe, thereby affecting the cooling effect of the steel pipe. Utility Model Content

[0006] In order to evenly cool the inside and outside of a steel pipe and improve the cooling effect of the steel pipe, the present application provides a cooling device for processing seamless steel pipes.

[0007] The present application provides a cooling device for seamless steel pipe processing, which adopts the following technical solution:

[0022] Preferably, the frame is connected with a collection box and a second blowing hood, the collection box is arranged at the lower end of the bearing rod, the top and bottom of the collection box are both opened, the second blowing hood is open toward the top of the collection box, and a second filter is obliquely arranged in the collection box.

[0023] By adopting the above technical solution, the steel pipe rolls from the bearing rod to the collection box after cooling, and falls onto the second filter net in an inclined state. The second blowing hood blows air to the steel pipe, which is convenient for blowing air inside the steel pipe, thereby reducing moisture in the steel pipe.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. After the steel pipe is placed on the bearing rod, the steel pipe can roll along the bearing rod on the bearing rod. At the same time, multiple first spray heads spray water to cool the outer peripheral wall of the steel pipe, and multiple second spray heads spray water to the inside of the steel pipe, so as to cool the inner peripheral wall of the steel pipe, and then cool the inside and outside of the steel pipe evenly, so as to improve the cooling effect of the steel pipe;

[0026] 2. After the steel pipe is placed on the load-bearing rod, the blocking member can prevent the steel pipe from rolling on the load-bearing rod.

[0027] 3. After the first spray head and the second spray head spray water to cool the steel pipe, the first blowing hood blows air to the steel pipe to dry the moisture on the outer wall of the steel pipe and reduce the residual moisture on the surface of the steel pipe.
