Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe heat treatment, in particular to an anti-offset structure for steel pipe heat treatment. Background Art

[0002] At present, in the production of the water quenching process, due to reasons such as the fixed length of the steel pipe, bending, wear of the rotating wheel, and angular offset of the rotating wheel, the steel pipe will generate an offset during rotation. The offset direction is difficult to determine, and continuous production cannot meet the normal process requirements. After the position of the steel pipe is offset, it has a great impact on the performance and outer diameter size of the steel pipe.

[0003] Therefore, we propose an anti-offset structure for steel pipe heat treatment to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-offset structure for steel pipe heat treatment to solve the problems in the above background art that in the current water quenching process production, due to reasons such as the fixed length of the steel pipe, bending, wear of the rotating wheel, and angular offset of the rotating wheel, the steel pipe will generate an offset during rotation. The offset direction is difficult to determine, and continuous production cannot meet the normal process requirements. After the position of the steel pipe is offset, it has a great impact on the performance and outer diameter size of the steel pipe.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An anti-offset structure for steel pipe heat treatment includes a bracket, a wheel disc, a chain, a rotating wheel and a water quenching nozzle. The rotating wheel supports and drives the steel pipe to rotate. The installation angle of the rotating wheel is offset from north to west. A column is installed below the water quenching nozzle, and the column is supported by a support member. When the end face of the steel pipe is facing the water quenching nozzle, the upper end face of the column is higher than the lowest face of the steel pipe, and the column blocks the contact between the steel pipe and the water quenching nozzle.

[0007] In a further embodiment, the installation angle of the rotating wheel is offset from north to west by °.

[0008] In a further embodiment, the column is rotatably connected to the support member.

[0009] In a further embodiment, the support member includes a base and a support rod. A bearing is installed at the bottom of the column, and the column is rotatably connected to the support rod through the bearing.

[0010] In a further embodiment, a cavity is opened upward at the bottom of the column, a turntable is installed at the inner top of the cavity, and the top of the support rod passes through the bearing and is movably connected to the turntable.

[0011] In a further embodiment, the height of the upright columns is one of 18 cm, 17 cm, 16 cm, 15 cm, and 14 cm respectively.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] This structure solves the problem of the steel pipe moving around during water quenching, ensures the stable performance of the steel pipe and the qualified outer diameter size. By slightly adjusting the angle of the rotating wheel, when the rotating wheel rotates in reverse, the steel pipe slowly moves westward. A self-made rotating upright column is provided below the water quenching nozzle. The functions of the rotating upright column are: blocking the steel pipe to prevent it from continuing to move westward and preventing the steel pipe from moving around and sleeving on the nozzle. Another function is: when the rotating wheel rotates, it drives the steel pipe to rotate. When the end face of the steel pipe contacts the upright column, it drives the upright column to rotate together, and the rolling friction is used to eliminate the frictional force of the upright column blocking the movement of the steel pipe around, ensuring that no scratches are generated on the end face of the steel pipe.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1-2 , an anti-offset structure for steel pipe heat treatment, which includes a bracket, a wheel disc 4, a chain 1, a rotating wheel 2 and a water quenching nozzle 5. The bracket supports the wheel disc 4 and the rotating wheel 2. There is a driving device inside the bracket. The driving device drives the wheel disc 4 to rotate through the chain 1. The wheel disc 4 drives the rotating wheel 2 to rotate through a shaft rod. The rotating wheel 2 supports and drives the steel pipe to rotate. The installation angle of the rotating wheel 2 is offset from north to west. A column 3 is installed below the water quenching nozzle 5. The column 3 is supported by a support member. When the end face of the steel pipe faces the water quenching nozzle 5, the upper end face of the column 3 is higher than the lowest surface of the steel pipe. The column 3 blocks the contact between the steel pipe and the water quenching nozzle 5.

[0021] Slightly adjust the angle of the rotating wheel 2. When the rotating wheel rotates in reverse, the steel pipe slowly moves westward. A self-made column 3 is made below the water quenching nozzle 5. The function of the column 3 is to block the steel pipe and prevent it from continuing to move westward, so as to prevent the steel pipe from moving and sleeving on the water quenching nozzle 5.

[0022] Specifically, the installation angle of the original water quenching wheel is adjusted from 0° of north-south to an offset of 5° from north to west, so that the steel pipe rotates and slowly moves westward and contacts the column 3.

[0023] Considering the wear problem, the column 3 is set to be rotatable. Specifically, the support member includes a base 7 and a support rod 6. A bearing 10 is installed at the bottom of the column 3. The column 3 is rotationally connected to the support rod 6 through the bearing 10. When the end face of the steel pipe contacts the column 3, it drives the column 3 to rotate together, and the rolling friction is used to eliminate the friction force of the column 3 blocking the movement of the steel pipe, ensuring that the end face of the steel pipe is not scratched.

[0024] According to the outer diameter of the steel pipe and the outer diameter of the paired nozzle, columns 3 of different sizes are selected. Currently, 5 specifications of columns 3 are made, and the heights are 18 cm, 17 cm, 16 cm, 15 cm, and 14 cm respectively. When changing the specifications and replacing the rotating columns of different specifications, the column 3 needs to be switched. Therefore, a cavity 8 is opened upward at the bottom of the column 3. A turntable 9 is installed on the inner top of the cavity 8. The top of the support rod 6 passes through the bearing 10 and is movably connected to the turntable 9, that is, the column 3 is movably sleeved on the support rod 6 and can be removed at any time for replacement.

[0025] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
