Description

Technical Field

[0001] This utility model belongs to the field of stainless steel pipe processing technology, specifically relating to a grinding and rust removal device for processing stainless steel pipe fittings. Background Technology

[0002] Stainless steel pipe processing is a broad and complex field involving multiple steps and processes to meet the needs of different industries and applications. The following is a comprehensive overview of stainless steel pipe processing: Stainless steel pipe processing mainly includes the following types: Cutting: Stainless steel pipes are cut to specified lengths or shapes using methods such as laser cutting, water jet cutting, plasma cutting, or mechanical cutting. Forming: This includes processes such as bending, folding, and rolling to shape stainless steel pipes into desired shapes, such as circles, squares, and rectangles. Welding: Stainless steel pipes or fittings are welded together using welding technologies such as argon arc welding and laser welding to form complete piping systems or structural components. Surface Treatment: Stainless steel pipes undergo polishing, wire drawing, pickling, and passivation treatments to improve their surface finish, corrosion resistance, and aesthetics. Custom Processing: Personalized processing is performed according to specific customer needs, such as drilling, grooving, necking, and flaring.

[0003] In the processing of stainless steel pipes, especially when grinding away surface rust on the outer wall, using a chuck to hold the pipe presents certain limitations, making it difficult to effectively grind the ends of the pipe. The following is a detailed description of this drawback: Limited Clamping Range: The chuck is primarily used to clamp the middle section of the stainless steel pipe to ensure its stability during grinding. However, this clamping method prevents the ends of the pipe, especially those tightly clamped by the chuck, from directly contacting the grinding tools. Therefore, surface rust and dirt in these areas are difficult to remove effectively. Impact of Clamping Force: To ensure the stainless steel pipe does not wobble or move during grinding, the chuck needs to apply a certain clamping force. This force can sometimes cause slight deformation or indentations in the clamped ends of the pipe, further increasing the difficulty of grinding. Necessity: Due to the limitations of chuck clamping, surface rust and dirt on the outer walls of the stainless steel pipe can only be treated manually. This includes manually grinding these hard-to-reach areas using tools such as sandpaper and wire brushes to ensure the cleanliness and consistency of the entire pipe surface. Challenges: High labor intensity: Manual processing requires significant physical exertion and time, especially when handling large or long stainless steel pipes, where the labor intensity increases substantially. High technical requirements: Manual grinding demands high levels of skill and experience from workers to ensure consistent and aesthetically pleasing results. Care must also be taken to avoid unnecessary damage to the steel pipe surface. Safety hazards: During manual processing, workers come into contact with grinding tools and potential splashes, posing certain safety risks. Therefore, appropriate protective measures must be taken, such as wearing protective eyewear, masks, and gloves. Utility Model Content

[0023] Please see Figure 1-3 The technical solution provided in this embodiment is as follows:

[0024] A grinding and rust removal device for processing stainless steel pipe fittings, comprising,

[0025] The worktable 1 and the chuck 3 are rotatably inserted into both sides of the inner wall of the worktable 1.

[0026] The grinding and rust removal assembly is located inside the workbench 1. The assembly includes a moving ring 2, a moving block 4, a moving table 7, a grinding disc 9, a torsion bar 10, a support spring 11, a grinding wheel 12, a support cylinder 13, a support wheel 15, a fine-tuning cylinder 16, a constraint frame 17, a moving wheel 18, and a drive assembly.

After grinding, the stainless steel pipe is stably moved by the moving wheels 18 to continuously remove rust from the outer walls of both ends of the stainless steel pipe, reducing the possibility of uncleaned areas of the stainless steel pipe. First, the stainless steel pipe supply device is placed on one side of the outer wall of the workbench 1. The stainless steel pipe is aligned with one side of the outer wall of the chuck 3 to facilitate its entry into the chuck 3. The chuck 3 is then used to hold the stainless steel pipe. The stainless steel tube continues to be clamped. An external motor screw is deployed at the bottom of the outer wall of the baffle 5, which drives the moving block 4 to move on the slide rail 8. Then, it drives the moving ring 2 to move. Subsequently, the chuck 3 drives the stainless steel tube to rotate, so that the grinding wheel 12, under the action of the torsion bar 10 and the support spring 11, continuously grinds the stainless steel tube. Rust and other impurities fall into the interior of the negative pressure shell 6. After the rust removal is completed, the drive motor 19 is started, which drives the moving wheel 18 to rotate and moves the stainless steel tube, so that the clamping end of the chuck 3 is exposed. After the rust removal is completed, the drive motor 19 is started again to discharge the stainless steel tube.

[0028] Specifically, the drive components include slide rail 8 and drive motor 19.

[0029] In a specific embodiment of this utility model, the drive component can ensure stable power transmission.

[0034] Specifically, a negative pressure shell 6 is fitted on one side of the outer wall of the grinding disc 9, and the negative pressure shell 6 is connected to an external negative pressure collection device through a pipe.

[0035] In a specific embodiment of this utility model, the negative pressure shell 6 is connected to an external negative pressure collection device via a pipe, which can continuously provide a negative pressure environment.

[0037] In a specific embodiment of this utility model, the output end of the support cylinder 13 is fixedly disposed at the center of one side of the outer wall of the support frame 14, which can ensure stable driving of the support frame 14.

[0038] Working principle:

[0039] By using the grinding and rust removal components, stable grinding and rust removal of stainless steel pipes of different sizes can be achieved. After grinding, the stainless steel pipe is stably driven to move by the moving wheels 18, completing continuous rust removal on the outer walls of both ends of the stainless steel pipe. This reduces the possibility of localized areas of the stainless steel pipe not being cleaned and rusted due to clamping. First, the stainless steel pipe supply device is placed on one side of the outer wall of the worktable 1. The stainless steel pipe is aligned with one side of the outer wall of the chuck 3 to facilitate its entry into the interior of the chuck 3. The chuck 3 continuously clamps the stainless steel pipe, and the rust removal is achieved through the outer... The motor lead screw is positioned at the bottom of the outer wall of the baffle 5, driving the moving block 4 to move on the slide rail 8, which in turn drives the moving ring 2 to move. Subsequently, the chuck 3 drives the stainless steel tube to rotate, causing the grinding wheel 12 to continuously grind the stainless steel tube under the action of the torsion bar 10 and the support spring 11. Rust and other impurities fall into the interior of the negative pressure shell 6. After rust removal is completed, the drive motor 19 is started, driving the moving wheel 18 to rotate and moving the stainless steel tube, exposing the clamping end of the chuck 3. After rust removal is completed, the drive motor 19 is started again to discharge the stainless steel tube.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
