Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe polishing, in particular to a polishing device for processing seamless stainless steel pipes. Background Art

[0002] Seamless steel pipe is a steel pipe made of a whole piece of metal with no seams on the surface. It is widely used in production and life. According to the production method, seamless pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, jacking pipes, etc.; the smoothness of the inner wall of the seamless steel pipe during production and use will affect the use effect, so the inner wall needs to be ground and polished to achieve the best use effect.

[0003] When the inner wall of a steel pipe is polished, in order to keep the inner wall clean, a polishing liquid is injected or sprayed into the steel pipe during the polishing process. The main function of this polishing liquid is to reduce the high temperature generated by polishing and help remove the debris generated during the polishing process. For example, the Chinese utility model patent document with reference announcement number CN214980162U describes a hot-rolled seamless steel pipe inner wall polishing device, which sprays polishing liquid into the steel pipe through an annular nozzle. However, there are some significant defects in the design of the above-mentioned annular nozzle. First, the polishing liquid sprayed by the annular nozzle will directly impact the steel pipe wall, which causes the polishing liquid to splash irregularly on the inside of the pipe wall, and part of the polishing liquid may even splash directly to the outside of the pipe. The environment around the equipment becomes humid, increasing the difficulty of operation and maintenance. Secondly, since the polishing liquid acts directly on the pipe wall, its subsequent fluidity mainly depends on the action of gravity to flow along the pipe wall. This flow mode may not be effective enough to remove debris stubbornly attached to the pipe wall.

[0004] Therefore, it is very necessary to invent a polishing device for processing seamless stainless steel pipe. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a polishing device for seamless stainless steel pipe processing, comprising a polishing frame, a polishing hydraulic cylinder, a cleaning polishing assembly, a clamping seat and a clamping hydraulic cylinder, wherein the polishing frame is fixedly mounted with a polishing hydraulic cylinder, the output end of the polishing hydraulic cylinder is fixedly connected to the cleaning polishing assembly, clamping seats are arranged on both sides below the cleaning polishing assembly, the output end of the clamping hydraulic cylinder is fixedly connected to the clamping seat, and is fixedly mounted on both sides of the outside of the polishing frame;

[0006] The cleaning polishing assembly includes a diffusion cleaning box, a cleaning hole, a driving component, a polishing disc, a chassis, a splash-proof tube, a reset spring, a top plate and an injection tube. A cleaning hole is opened on the outside of the diffusion cleaning box, and a driving component is fixedly installed at the bottom of the diffusion cleaning box. The output end of the driving component is fixedly connected to the polishing disc, and the polishing disc is located on the inner side of the chassis. The chassis is fixedly connected to the top plate through the splash-proof tube and the reset spring. The upper end of the injection tube passes through the top plate and is connected to the cleaning injection tube. The lower end of the injection tube is connected to the diffusion cleaning box. The diffusion cleaning box is fixedly connected to the top plate through a vertical rod, and the top plate is fixedly connected to the output end of the polishing hydraulic cylinder.

[0007] Preferably, the cleaning hole opened on the diffusion cleaning box is tangent to its inner cavity, that is, the edge of the cleaning hole is connected to the inner cavity of the diffusion cleaning box, and the axis of the cleaning hole forms a downward inclination angle with the bottom surface of the inner cavity of the diffusion cleaning box, and the liquid will be discharged along the cleaning hole at a downward inclination.

[0008] Preferably, the driving component is composed of a sealing cover and a motor, and the motor output end of the driving component is fixedly connected to the polishing disk, and the polishing disk is located below the diffusion cleaning box, that is, above the chassis.

[0009] Preferably, the splash-proof tube and the return spring sleeve are arranged outside the diffusion cleaning box, the driving component and the polishing disk, and the splash-proof tube is arranged outside the return spring, and the splash-proof tube is a telescopic bellows sleeve.

[0010] Preferably, the top plate is elastically connected to the bottom plate via the return spring; and the liquid injection tube is located on one side of the vertical rod of the diffusion cleaning box.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model is designed with a diffusion cleaning box to optimize the spraying method of the polishing liquid. The design enables the polishing liquid to be sprayed obliquely onto the wall of the steel pipe at a certain angle, forming an oblique impact, thereby more effectively cleaning the inner wall of the steel pipe. It ensures that the direction in which the polishing liquid is sprayed has a certain downward tilt angle. This spraying method not only enhances the impact force of the polishing liquid on the pipe wall, but also makes it easier for the liquid to flow along the pipe wall after the impact. Due to the tangential component generated by the oblique injection, the subsequent fluidity of the liquid column is significantly enhanced, and the flow rate is also increased accordingly. Under the combined action of gravity, this flow pattern enables the polishing liquid to form a downward spiral flow on the inner wall of the steel pipe, thereby more effectively removing the debris and residues generated during the polishing process.

[0013] In addition, in order to reduce the waste caused by the splash of polishing liquid and the impact on the environment around the equipment, the splash-proof cylinder and the return spring are cleverly designed. The splash-proof cylinder can effectively block the splashing polishing liquid and prevent it from splashing directly out of the steel pipe, thereby avoiding the problem of humidity in the environment around the equipment. The return spring is responsible for maintaining the stability and reliability of the splash-proof cylinder, ensuring that it can always play an effective role during the working process.

[0023] The cleaning polishing assembly 3 includes a diffusion cleaning box 31, a cleaning hole 32, a driving component 33, a polishing disc 34, a chassis 35, a splash-proof tube 36, a reset spring 37, a top plate 38 and an injection tube 39.

The output end of the driving component 33 is fixedly connected to the polishing disc 34. The polishing disc 34 is located on the inner side of the chassis 35. The chassis 35 is fixedly connected to the top plate 38 through the splash-proof tube 36 and the reset spring 37. The upper end of the injection tube 39 passes through the top plate 38 and is connected to the cleaning injection tube. The lower end of the injection tube 39 is connected to the diffusion cleaning box 31. The diffusion cleaning box 31 is fixedly connected to the top plate 38 through a vertical rod. The top plate 38 is fixedly connected to the output end of the polishing hydraulic cylinder 2.

[0024] Embodiment 1:

[0025] Specifically, the cleaning hole 32 opened on the diffusion cleaning box 31 is tangent to its inner cavity, that is, the edge of the cleaning hole 32 is connected to the inner cavity of the diffusion cleaning box 31, and the axis of the cleaning hole 32 forms a downward tilt angle with the bottom surface of the inner cavity of the diffusion cleaning box 31, and the liquid will be discharged downward along the cleaning hole 32. The design of the cleaning hole 32 is ingeniously tangent to its inner cavity, ensuring that the liquid can be discharged downward along the cleaning hole at a certain tilt angle, forming a downward spiral flow. This design not only improves the utilization efficiency of the polishing liquid, but also effectively avoids the waste of the polishing liquid.

[0026] Specifically, the driving component 33 is composed of a sealing cover and a motor, which provides rotational power for the polishing disc 34. When the motor is started, the polishing disc 34 rotates at a high speed to polish the inner wall of the seamless stainless steel pipe. The motor output end of the driving component 33 is fixedly connected to the polishing disc 34, and the polishing disc 34 is located below the diffusion cleaning box 31, that is, above the bottom plate 35.

[0027] Specifically, the splash-proof tube 36 and the return spring 37 are sleeved on the outside of the diffusion cleaning box 31, the driving component 33 and the polishing disc 34, and the splash-proof tube 36 is arranged on the outside of the return spring 37. This design is to prevent splashing during the polishing process. The splash-proof tube 36 adopts a telescopic corrugated sleeve structure, which can effectively block the splashing polishing liquid and prevent it from spreading. The return spring 37 is responsible for maintaining the stability and elasticity of the splash-proof tube 36 to ensure that it can always play an effective role during the working process.

[0028] Specifically, the top plate 38 is elastically connected to the bottom plate 35 through the return spring 37; the injection pipe 39 is located on one side of the vertical pole of the diffusion cleaning box 31. This connection method not only ensures the stability of the entire device, but also enables the polishing disc 34 to maintain a certain degree of floating during the polishing process, thereby better adapting to steel pipes of different diameters. The injection pipe 39 is responsible for injecting the polishing liquid from the outside into the diffusion cleaning box 31 to provide necessary lubrication and cooling for the polishing operation.

[0029] Embodiment 2:

[0030] First, the seamless stainless steel pipe is placed in the clamp seat 4 and fixed by the clamping hydraulic cylinder 5 to ensure the stability of the steel pipe during the polishing process. The polishing hydraulic cylinder 2 is started to push the cleaning polishing assembly 3 to the inner wall of the seamless stainless steel pipe. The polishing disc 34 in the cleaning polishing assembly 3 starts to rotate at high speed under the drive of the motor of the driving component 33. At this time, the injection pipe 39 starts to inject the polishing liquid, and the polishing liquid enters the inner cavity of the diffusion cleaning box 31 through the injection pipe 39. The cleaning hole 32 opened on the diffusion cleaning box 31 is tangent to its inner cavity, and the axis of the cleaning hole 32 forms a downward inclination angle with the bottom surface of the inner cavity of the diffusion cleaning box 31. Therefore, the polishing liquid will be discharged downward along the cleaning hole 32 at a certain inclination angle, forming a downward spiral flow. And under the high-speed rotation of the polishing disc 34, the pipe wall is polished evenly and efficiently. At the same time, due to the existence of the spiral flow, the polishing liquid can also bring the debris and residues generated during the polishing process downward, which is conducive to subsequent cleaning work. During the polishing process, the splash-proof cylinder 36 and the return spring 37 prevent the polishing liquid from splashing. The splash-proof cylinder 36 can effectively block the splashing polishing liquid and prevent it from spreading. The return spring 37 is responsible for maintaining the stability and elasticity of the splash-proof cylinder to ensure that it can always play an effective role during the working process. When the polishing is completed, the polishing hydraulic cylinder 2 is retracted, and the cleaning polishing assembly 3 is separated from the seamless stainless steel pipe. Prepare for the next polishing operation.
