Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically to a stainless steel pipe inner wall polishing device. Background Technology

[0002] Stainless steel pipes are tubular components made of stainless steel, characterized by strong corrosion resistance, high strength, and aesthetic appeal. Their main components include elements such as iron, chromium, and nickel, with chromium content typically not less than 10.5%. This chromium content forms a dense passivation film on the surface, effectively resisting corrosion from air, water, acids, and alkalis. Due to their excellent comprehensive performance, stainless steel pipes are widely used in food machinery, medical devices, building curtain walls, rail transportation, and other fields, making them an indispensable material in modern industry and daily life.

[0003] In the production and application of stainless steel pipes, inner wall polishing is one of the key processes, but the existing process has significant drawbacks. Due to the limitations of polishing equipment, one end of the pipe often cannot be fully reached during polishing, requiring the pipe to be switched at both ends and re-clamped for repeated polishing. This operation not only prolongs the processing cycle but also increases equipment wear and labor costs. Furthermore, after polishing, the pipes are often directly stacked and stored due to the tight production line schedule, lacking sufficient time for detailed inspection of each pipe. When subsequent quality inspection reveals defects such as scratches or substandard roughness on the inner wall, it is necessary to search through the entire stack of pipes one by one for the problematic pieces, which is quite cumbersome. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a stainless steel pipe inner wall polishing device that can polish from both ends in one go, and can be pre-stored on a shelf and stacked after inspection to ensure it is correct.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a stainless steel pipe inner wall polishing device, comprising:

[0006] The bracket includes a support plate and support legs, wherein the support legs are fixedly disposed at the four corners below the support plate;

[0007] The clamping assembly includes a roller and a pressure roller. The rollers are fixed on the support plate and arranged in pairs in a straight line. The rollers in the same group are parallel to each other. Each roller is driven by a motor. The pressure roller is located above the rollers and corresponds to each group of rollers. It is located directly above the gap between the rollers in the same group and is driven to move up and down synchronously by a cylinder fixed on the bracket.

[0008] The polishing rods are symmetrically arranged on both sides of the clamping assembly above the support plate and are driven to rotate by motor two. The motor two is driven by an electric push rod fixed on the support plate to move along the direction of the pressure roller arrangement. The polishing rods are equipped with polishing teeth and cleaning brushes.

[0009] The shelving is fixed above the support plate and has several arc-shaped pipe grooves.

[0010] Furthermore, the lower end of the support leg is provided with an anti-slip pad.

[0011] Furthermore, the pressure roller is fixedly installed below the same connecting plate, and a U-shaped frame is fixedly installed on the support plate at both ends of the connecting plate. The cylinder is fixedly installed on the two U-shaped frames, which drive the two ends of the connecting plate to rise and fall synchronously.

[0012] Furthermore, the polishing teeth and cleaning brush are equidistantly arranged around the polishing rod.

[0013] Furthermore, the upper wall of the shelf is inclined, the arc-shaped tube grooves are arranged along the inclined direction, and an integrally formed height-increasing edge is provided at the upper edge of the shelf.

[0014] Furthermore, a dust collection box is fixedly provided on the support plate at both ends of the clamping assembly. The dust collection box has an opening facing the polishing rod, and its side wall has a connection port for connecting to an external dust collection device.

[0015] Compared with existing technologies, the advantages of this invention are as follows: the polishing rods are symmetrically arranged on both sides of the clamping assembly, and the design allows for polishing from both ends in one step. This fully utilizes the polishing teeth and cleaning brushes arranged around the polishing rods, ensuring all-around contact with the pipe wall and significantly improving polishing efficiency. Compared with traditional single-end polishing or multiple polishing operations, this not only saves operation time but also reduces damage to the steel pipe caused by repeated clamping.

[0016] The shelving allows for the temporary storage of polished steel pipes, enabling workers to promptly inspect the polishing effect without affecting subsequent processing, thus preventing batch rework due to undetected defects. Simultaneously, the beveled design and curved pipe grooves facilitate retrieval, while the retaining edges ensure storage safety. The entire process is compact and efficient, guaranteeing polishing quality while optimizing workflow and enhancing the convenience and orderliness of production management.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 A stainless steel pipe inner wall polishing device includes: a support, including a support plate 1 and support legs 2. The support legs 2 are fixedly installed at the four corners below the support plate 1. The lower end of the support legs 2 is provided with anti-slip pads, which can enhance the stability of the device and prevent displacement due to vibration during operation. It is especially suitable for smooth ground environments.

[0024] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 The clamping assembly includes a support roller 3 and a pressure roller 4. The support rollers 3 are fixedly mounted on the support plate 1 and arranged in pairs in a straight line. The support rollers 3 in the same group are parallel to each other. Each support roller 3 is driven by a motor 5. The pressure roller 4 is located above the support rollers 3 and corresponds one-to-one with each group of support rollers 3. It is located directly above the gap between the support rollers 3 in the same group and is driven to move up and down synchronously by a cylinder 6 fixed on the bracket. The pressure roller 4 is fixedly mounted below the same connecting plate 14. U-shaped frames 15 are fixedly mounted on the support plate 1 at both ends of the connecting plate 14. The cylinder 6 is fixed on two U-shaped frames 15 and drives the two ends of the connecting plate 14 to move up and down synchronously, ensuring that multiple groups of pressure rollers apply uniform pressure to the steel pipe for stable fixation and avoiding uneven local force that may cause polishing deviation.

[0025] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 The polishing rod 7 is symmetrically arranged on both sides of the clamping assembly above the support plate 1 and is driven to rotate by the second motor 8. The second motor 8 is driven by the electric push rod 9 fixed on the support plate 1 to move along the arrangement direction of the pressure roller 4. The polishing rod 7 is provided with polishing teeth 10 and cleaning brush 11. The polishing teeth 10 and cleaning brush 11 are equidistantly arranged around the polishing rod 7, which can treat the pipe wall in all directions. While improving the polishing efficiency, it can remove debris in time and reduce secondary wear.

[0026] Combined with appendix Figure 1 Appendix Figure 4The shelf 12 is fixedly mounted above the support plate 1 and has several arc-shaped pipe grooves 13. The upper wall of the shelf 12 is inclined, and the arc-shaped pipe grooves 13 are arranged along the inclined direction. An integrally formed raised edge 16 is provided at the upper edge of the shelf 12 to facilitate the retrieval and inspection of stainless steel pipes. The edge can prevent the steel pipes from rolling off and improve storage safety.

[0027] Combined with appendix Figure 1 Appendix Figure 3 The support plate 1 is fixedly provided with a dust collection box 17 at both ends of the clamping assembly.

[0028] The specific implementation of this utility model is as follows: The device is placed on a stable ground via the anti-slip pads at the lower end of the support legs 2 to ensure working stability, and the device is connected to an external power source. The stainless steel tube to be polished is placed on a pair of rollers 3, and the cylinder 6 is activated to drive the pressure roller 4 to descend, so that the pressure roller 4 cooperates with the rollers 3 to firmly clamp the stainless steel tube and prevent the stainless steel tube from shifting during polishing.

[0029] Motor 5 is activated to rotate roller 3, causing the stainless steel tube to rotate. Simultaneously, motor 8 is activated to drive polishing rod 7 to rotate. Electric push rod 9 pushes polishing rod 7 to move along the arrangement direction of pressure roller 4, allowing polishing teeth 10 and cleaning brush 11 on polishing rod 7 to extend into the inner wall of the stainless steel tube from both ends, achieving all-round polishing and immediate debris removal. When the two polishing rods 7 are close together, only the center of the stainless steel tube remains unpolished. Simply control one end of electric push rod 9 to move polishing rod 7 out of the stainless steel tube, while the other end continues to move polishing rod 7 forward, thus polishing the center of the stainless steel tube.

[0030] During the polishing process, the dust collection boxes 17 located at both ends of the clamping assembly are connected to an external dust collection device through the connection port 18 to promptly remove the metal dust generated during polishing from both ends of the stainless steel tube. After polishing is completed, the pressure roller 4 is raised to remove the stainless steel tube, which is then placed on the shelf 12 for inspection. After confirmation that everything is in order, it is stacked.
