Description

Technical Field

[0001] The utility model provides a cooling device for precision steel pipe production, belonging to the technical field of precision steel pipe processing. Background Art

[0002] Precision steel pipe is a high-precision steel pipe material that has been processed by cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipe, no leakage under high pressure, high precision, high finish, no deformation when cold bending, no cracks when flaring or flattening, it is mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders. It can be seamless pipe or welded pipe.

[0003] Based on the above, the inventors found that:

[0004] In the existing technology, most of the cooling methods are outer wall cooling or placing the steel pipe in a cooling tank for cooling. The inner wall cannot be cooled by simply relying on the outer wall cooling, resulting in poor cooling effect, and the specific position cannot be adjusted according to the length of the steel pipe.

[0005] Therefore, in view of this, the existing structure is studied and improved, and a cooling device for precision steel pipe production is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is that the traditional cooling device for precision steel pipe production cannot cool the inner wall of the pipe and cannot adjust the position of the high-pressure nozzle according to the length of the steel pipe.

[0007] In order to solve the above problems, the utility model proposes a technical solution: a cooling device for precision steel pipe production, including a conveying device, an upper spray cooling assembly, and a recovery tank. The precision steel pipe is placed on the conveying device and is located below the upper spray cooling assembly. A precision steel pipe internal auxiliary cooling assembly is provided on one side of the recovery tank, and the precision steel pipe internal auxiliary cooling assembly includes a driving assembly, a high-pressure nozzle, a connecting column, a mounting plate, and a mounting frame. The mounting plate is L-shaped and fixedly connected to the connecting column.

[0008] Furthermore, a through hole is opened on the side wall of the recovery tank, and the connecting column is placed in the through hole and adapted to the inner diameter of the through hole.

[0009] Furthermore, the mounting frame is placed on one side of the recovery tank and is fixedly connected to the recovery tank, and a limiting groove is provided on the mounting frame. The lower end of the mounting plate is fixedly connected to a limiting block, and the limiting block is placed in the limiting groove.

[0010] Furthermore, the high-pressure nozzle is fixedly connected to the connecting column and is externally connected to a connecting pipe. When the high-pressure nozzle moves to the maximum extent, there is a distance between the high-pressure nozzle and the inner wall of the recovery tank.

[0011] Furthermore, the driving assembly includes a motor, gear 1, gear 2, and a threaded rod. The threaded rod is rotatably connected between the mounting frame and the outer wall of the recovery tank. The motor is fixedly connected to the inner side of the mounting frame and the output end of the motor is fixedly connected to gear 1. The gear 1 is meshed with the gear 2 and the gear 2 is fixedly connected to the threaded rod. The limit block is threadedly connected to the threaded rod.

[0012] Furthermore, a mounting cover is fixedly connected to the outer side of the high-pressure nozzle, and a groove is formed between the inner wall of the mounting cover and the high-pressure nozzle.

[0013] Due to the adoption of the above technical solution, the beneficial effects of the cooling device for precision steel pipe production of the utility model are as follows:

[0014] 1. Through the setting of high-pressure nozzles, the inside of the precision steel pipe is flushed and cooled, which can cool the inside of the pipeline. In combination with the spray cooling component, the outer wall of the steel pipe is cooled to provide a cooling effect.

[0015] 2. By coordinating the setting of the high-pressure nozzle with the driving component, the position of the high-pressure nozzle can be adjusted according to the length of the steel pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figure 1-4 As shown in the utility model provides a kind of cooling device for precision steel pipe production: including conveying device 1, upper spray cooling assembly 2, recovery tank 3, the precision steel pipe is placed on conveying device and is located below upper spray cooling assembly component 2, the recovery tank 3 side is provided with precision steel pipe internal auxiliary cooling assembly and precision steel pipe internal auxiliary cooling assembly includes drive assembly, high-pressure spray head 4, connecting column 5, mounting plate 6, mounting bracket 7, the mounting plate 6 is L type and is fixedly connected with connecting column 5, the drive assembly includes motor 10, gear one 11, gear two 12, threaded rod 13, the threaded rod 13 is rotatably connected between mounting bracket 7 and the outer wall of recovery tank 3, the motor 10 is fixedly connected in mounting bracket 7 inner side and the output end of motor 10 is fixedly connected with gear one 11, the gear one 11 is engaged with gear two 12 and gear two 12 is fixedly connected on threaded rod 13, the limit block 14 is threadedly connected with threaded rod 13.

[0026] As Figure 2-4 As shown, the recovery tank 3 side wall is provided with through hole 8 and connecting column 5 is placed in through hole 8 and is adapted with its inner diameter.

[0027] The mounting bracket 7 is placed on one side of the recovery tank 3 and is fixedly connected, and the mounting bracket 7 is provided with a limiting groove 9, the lower end of the mounting plate 6 is fixedly connected with a limiting block 14, and the limiting block 14 is placed in the limiting groove 9.

[0028] The high-pressure spray head 4 is fixedly connected with the connecting column 5 and is connected with the connecting pipe 15, when the high-pressure spray head 4 moves to the maximum limit, there is a distance between the high-pressure spray head 4 and the inner wall of the recovery tank 3.

[0029] The high-pressure spray head 4 is fixedly connected with the mounting cover 16 on the outside, and the recess 17 is formed between the inner wall of the mounting cover 16 and the high-pressure spray head 4.

[0030] The principle of the cooling device for precision steel pipe production in this utility model is:

[0031] The conveying device is a device for conveying precision steel pipes. The upper spray cooling assembly refers to a cooling method that sprays from the top downward to the surface of the precision steel pipe. The recovery tank is used to recover the sprayed coolant to prevent it from splashing to other places. All of the above can be achieved through existing technologies, without a doubt.

[0032] The conveying device conveys the precision steel pipe to the appropriate position, and the connecting pipe is externally connected to the water supply device of the existing technology. The coolant is sprayed out from the high-pressure nozzle, sprayed into from one end of the precision steel pipe, and sprayed out from the other end. This is the range of the high-pressure nozzle spray. When the steel pipe is relatively short, the starting motor drives gear one, gear two, and threaded rod to rotate, and the limit block is threadedly connected to the threaded rod, thereby driving the limit block to move in the limit groove, and the connecting column moves in the through hole, driving the mounting plate, connecting column, and high-pressure nozzle to approach the mouth of the precision steel pipe for high-pressure flushing to assist cooling. When the precision steel pipe is close to the inner wall of the groove, it is the maximum range of the high-pressure nozzle to extend into the precision steel pipe. It should be noted here that the groove must be large enough. The conveying position of the conveying device is not necessarily very precise, and there will be a certain error. It is sufficient to extend the head of the high-pressure nozzle into or close to the mouth of the precision steel pipe. The more precision steel pipes are inserted or too close to the mouth of the pipe, the temperature at the mouth of the pipe will be high or it will not be flushed, and the internal cooling effect will be poor.

[0033] The distance between the high-pressure nozzle and the recovery tank, such as Figure 1-2 As shown, since the connecting pipe is placed between the high-pressure nozzle and the inside of the recovery tank, if there is no gap, the connecting pipe will bend under pressure, resulting in poor liquid discharge effect of the high-pressure nozzle.

[0034] The utility model can cool the inner wall of the pipeline and adjust the position of the high-pressure nozzle according to the length of the steel pipe by arranging the auxiliary cooling component inside the precision steel pipe.

[0035] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
