Description

Technical Field

[0001] This utility model relates to the field of rust removal device technology, and in particular to a rust removal device for steel structure processing. Background Technology

[0002] In the field of steel structure processing, steel is the core raw material. During production, storage and transportation, its surface is prone to forming an oxide and rust layer due to contact with air, moisture, dust or corrosive media. If this rust layer is not removed, it will directly affect the quality of subsequent processing. Therefore, rust removal of steel structures is a key preliminary process to ensure the processing accuracy of steel structures, improve the corrosion resistance of components, and ensure their safe and reliable service in various application scenarios.

[0003] Existing rust removal devices for steel structure processing can achieve ideal rust removal results when working on planar steel structural parts because the grinding rollers can form a stable and sufficient contact with the workpiece surface. However, when dealing with cylindrical steel structural parts (such as steel columns and steel pipes), the grinding rollers of traditional rust removal devices are mostly designed to be planar or have a fixed curvature due to the influence of the workpiece's curved surface shape. They can only form local line contact or small-area point contact with the outer surface of the cylindrical workpiece, and the contact range is very limited. This not only results in a small coverage area for a single rust removal operation, requiring repeated adjustments to the workpiece position or grinding angle to complete the overall rust removal, which significantly reduces the rust removal efficiency, but also easily leads to problems such as incomplete rust removal in some areas and inconsistent surface roughness due to uneven grinding force. It is difficult to guarantee the rust removal quality and cannot meet the surface accuracy requirements of subsequent processing of cylindrical steel structural parts, thus its practicality is not high. Summary of the Invention

[0004] This utility model relates to a rust removal device for steel structure processing, which includes a rust removal component. The rust removal component innovatively adopts a belt grinding structure design. When working in conjunction with a workpiece chuck, the belt grinding component, with its flexible adaptability, can closely conform to the arc-shaped outer surface of the cylindrical steel structure, forming a large-area, uniform contact grinding zone. This effectively avoids the problem of insufficient contact between traditional rigid grinding components and arc-shaped surfaces. During the stable rotation of the cylindrical steel structure driven by the workpiece chuck, the belt grinding component can continuously and comprehensively grind and clean the rust layer on the workpiece surface. This significantly reduces the number of steps required to repeatedly adjust the workpiece or grinding components, greatly improving the efficiency of rust removal. It also ensures uniform grinding force across all areas of the workpiece surface, effectively avoiding incomplete rust removal or over-grinding in certain areas. This guarantees the flatness and smoothness of the cylindrical steel structure surface after rust removal, significantly improving the quality of rust removal. It is highly flexible and practical.

[0005] This utility model provides a steel structure processing rust removal device, specifically including: an installation component, which includes an installation base and a workpiece chuck, the workpiece chuck being rotatably connected inside the installation base and driven to rotate by a drive motor; and a rust removal component, which consists of a moving mechanism and a rust removal mechanism. The moving mechanism includes a displacement frame, an electric push rod, a rust-removing motor, and a drive rod. The displacement frame is inserted into the top of the mounting base, and the electric push rod is fixedly installed inside the mounting base. One end of the push rod of the electric push rod is fixedly installed on the side of the displacement frame. The rust-removing motor is fixedly installed inside the displacement frame. The drive rod is rotatably connected inside the displacement frame, and one end of the drive rod is drively connected to the rotating shaft of the rust-removing motor. The rust-removing mechanism includes a transmission auxiliary roller, a transmission main roller, a rust-removing belt, and a retainer. The retainer is inserted into the side of the displacement frame, and the transmission auxiliary roller is rotatably connected to the front side of the displacement frame. The transmission main roller is rotatably connected to the side of the retainer, and the rust-removing belt is installed outside the transmission auxiliary roller and the transmission main roller.

[0006] Furthermore, the displacement frame is a "U" shaped frame, and two transmission rollers are provided, which are symmetrically arranged on the front side of the displacement frame.

[0007] Furthermore, the bottom of the main drive roller is provided with a drive gear, and the bottom of the cage is provided with a drive gear, and the drive gear and the drive gear mesh to drive each other.

[0008] Furthermore, the cross-sectional shape of the drive rod is a regular polygon, and the inside of the drive gear is provided with a drive groove, with the regular polygonal cross-section of the drive rod inserted into the inside of the drive groove.

[0009] Furthermore, the side of the retainer is provided with a tensioning top spring, and the two ends of the tensioning top spring abut against the side of the retainer and the side of the displacement frame, respectively.

[0010] This utility model provides a rust removal device for steel structure processing, which has the following beneficial effects: The rust removal component innovatively adopts a belt grinding structure design. When working in conjunction with the workpiece chuck, the belt grinding component, with its flexible adaptability, can closely conform to the curved outer surface of the cylindrical steel structure, forming a large-area, uniform contact grinding zone. This effectively avoids the problem of insufficient contact between traditional rigid grinding components and curved surfaces. As the workpiece chuck drives the cylindrical steel structure to rotate stably, the belt grinding component can continuously and comprehensively grind and clean the rust layer on the workpiece surface. This significantly reduces the number of steps required to repeatedly adjust the workpiece or grinding components, greatly improving the efficiency of rust removal. It also ensures that the grinding force is uniform across all areas of the workpiece surface, effectively avoiding incomplete rust removal or over-grinding in certain areas. This guarantees the flatness and smoothness of the cylindrical steel structure surface after rust removal, significantly improving the quality of rust removal and enhancing the flexibility and practicality of the device.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please refer to Figures 1 to 5 Example 1: This utility model proposes a rust removal device for steel structure processing, including: a mounting component 1, which includes a mounting base 101 and a workpiece chuck 102, the workpiece chuck 102 being rotatably connected inside the mounting base 101 and driven to rotate by a drive motor; it also includes a rust removal component, which consists of a moving mechanism 2 and a rust removal mechanism 3. The moving mechanism 2 includes a displacement frame 201, an electric push rod 202, a rust-removing motor 203, and a drive rod 204. The displacement frame 201 is inserted into the top of the mounting base 101, and the electric push rod 202 is fixedly installed inside the mounting base 101. One end of the push rod of the electric push rod 202 is fixedly installed on the side of the displacement frame 201. The rust-removing motor 203 is fixedly installed inside the displacement frame 201, and the drive rod 204 is rotatably connected inside the displacement frame 201. One end of the rod of 204 is connected to the shaft of the rust removal motor 203; the rust removal mechanism 3 includes a transmission auxiliary roller 301, a transmission main roller 302, a rust removal belt 303 and a retainer 304. The retainer 304 is inserted into the side of the displacement frame 201, and the transmission auxiliary roller 302 is rotatably connected to the front side of the displacement frame 201. The transmission main roller 301 is rotatably connected to the side of the retainer 304, and the rust removal belt 303 is installed on the outside of the transmission auxiliary roller 301 and the transmission main roller 302.

[0021] The displacement frame 201 is a U-shaped frame, and two transmission auxiliary rollers 301 are provided. The two transmission auxiliary rollers 301 are symmetrically arranged on the front side of the frame of the displacement frame 201. In use, the moving mechanism 2 can drive the rust removal mechanism 3 to move, thereby adhering the rust removal strip 303 to the cylindrical steel structure fixed by the workpiece chuck 102 for rust removal. When the electric push rod 202 extends and retracts, it can drive the displacement frame 201 to move on the top of the mounting base 101, thereby changing the usage position of the rust removal mechanism 3. It is convenient and flexible to use, and quick to adjust. After the cylindrical steel structure is fixed on the workpiece chuck 102, the rust removal motor 203 and the drive motor can be turned on to realize the rust removal operation on the cylindrical steel structure. The bottom of the transmission main roller 302 is provided with a transmission gear 3021, and the bottom of the retainer 304 is... The component is equipped with a drive gear 3041, which meshes with the transmission gear 3021. The drive rod 204 has a regular polygonal cross-section, and the drive gear 3041 has a drive groove 3042 inside. The polygonal cross-section of the drive rod 204 is inserted into the drive groove 3042. When the rust removal motor 203 is powered on, it can drive the drive rod 204 to rotate. When the drive rod 204 rotates, it can drive the drive gear 3041 to rotate through the drive groove 3042. When the drive gear 3041 rotates, it can drive the transmission main roller 302 to rotate through the transmission gear 3021. Thus, under the combined action of the transmission main roller 302, the rust removal belt 303, and the two transmission auxiliary rollers 301, the rust removal belt 303 can perform rust removal on the surface of the cylindrical steel structure.

[0022] The retainer 304 has a tension spring 3043 on its side, with both ends of the tension spring 3043 abutting against the side of the retainer 304 and the side of the displacement frame 201, respectively. During use, the tension spring 3043 keeps the rust-removing strip 303 under constant tension and also adjusts the grinding and rust-removing pressure of the rust-removing strip 303 on the cylindrical steel structure during rust removal operations. This allows it to adapt to different conditions and perform rust removal operations. The electric push rod 202 moves the displacement frame 201, causing the rust-removing strip 303 to abut against the surface. After the displacement frame 201 moves towards the cylindrical steel structure, the rust removal belt 303 will be subjected to resistance and compression, causing the rust removal belt 303 to pull the transmission main roller 302 to move. When the transmission main roller 302 moves, it can compress the tension top spring 3043, thereby increasing the grinding and rust removal pressure of the rust removal belt 303 on the surface of the cylindrical steel structure. Thus, the grinding and rust removal pressure of the rust removal belt 303 can be adjusted by adjusting the actual use position of the displacement frame 201. It is convenient, flexible and highly adaptable.

[0023] The working principle of this embodiment is as follows: The moving mechanism 2 can drive the rust removal mechanism 3 to move, thereby attaching the rust removal strip 303 to the cylindrical steel structure fixed by the workpiece chuck 102 for rust removal. When the electric push rod 202 extends or retracts, it can drive the displacement frame 201 to move at the top of the mounting base 101, thereby changing the usage position of the rust removal mechanism 3. After the cylindrical steel structure is fixed on the workpiece chuck 102, the power of the rust removal motor 203 and the drive motor can be turned on to realize the rust removal operation on the cylindrical steel structure. After the rust removal motor 203 is powered on, it can drive the drive rod 204 to rotate. When the drive rod 204 rotates, it can drive the drive gear 3041 to rotate through the drive groove 3042. When the drive gear 3041 rotates, it can drive the drive main roller 302 to rotate through the transmission gear 3021. Thus, under the combined action of the drive main roller 302, the rust removal strip 303 and the two drive auxiliary rollers 301, rust removal is achieved. The belt 303 can be used to remove rust from the surface of cylindrical steel structural parts. The tension spring 3043 can keep the rust removal belt 303 in a taut state at all times. At the same time, it can also adjust the grinding and rust removal pressure of the rust removal belt 303 on the cylindrical steel structural parts during the rust removal operation. Thus, it can adapt to different situations to achieve the function of rust removal operation. The electric push rod 202 drives the displacement frame 201 to move so that the rust removal belt 303 comes into contact with the surface of the cylindrical steel structural parts. When the displacement frame 201 continues to move towards the cylindrical steel structural parts, the rust removal belt 303 will be subjected to the resistance and compression, which will cause the rust removal belt 303 to pull the transmission main roller 302 to move. When the transmission main roller 302 moves, it can compress the tension spring 3043, thereby increasing the grinding and rust removal pressure of the rust removal belt 303 on the surface of the cylindrical steel structural parts. Thus, the grinding and rust removal pressure of the rust removal belt 303 can be adjusted by adjusting the actual use position of the displacement frame 201.
