Abstract
Description
Technical Field
[0001] This utility model relates to the field of deburring technology, specifically a deburring device for metal railing processing. Background Technology
[0002] The core function of deburring metal railings is to eliminate sharp protrusions left after processing. This ensures safety during use, prevents people from being scratched when they come into contact with the railings, improves the appearance and texture of the railings, making the surface smoother, and also ensures the quality of subsequent processing steps such as painting and welding, thus improving the overall performance and quality of the railings.
[0003] When railings are installed in humid, dusty, or corrosive environments, an anti-corrosion coating needs to be applied to the exterior to prevent rust. However, railings are not cast in one piece; they are composed of multiple tubular railings. When replacing a deformed single tubular railing, it needs to be disassembled. To prevent internal corrosion and rust from penetrating the inner side of the railing, an anti-rust coating is also applied to the interior in special environments. However, due to the narrow internal space, the uniformity of the anti-corrosion coating cannot be visually inspected after application. Sharp burrs can easily cause the coating to crack and peel off, leaving unprotected areas. These areas can then become the starting point for corrosion, leading to "pitting corrosion expansion," which can cause the entire anti-corrosion layer to fail. As rust gradually penetrates the inner side of the railing, the coating will eventually penetrate. Therefore, to ensure the service life of the anti-corrosion layer, the interior of the railing is usually deburred before applying the anti-corrosion coating.
[0004] However, the conventional deburring device is just a high-speed rotating wire brush. This simple wire brush can grind burrs when rotating at high speed. In order to prevent burrs from flying, an exhaust fan is usually installed on the side. However, when grinding burrs inside the railing, because the inside of the railing is thin and long and is not affected by the external air, the conventional exhaust fan cannot clean up the debris and burrs that have fallen off inside the railing in time. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a deburring device for metal railing processing, which has the advantages of timely cleaning of burrs and debris that fall off the railing, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a deburring device for processing metal railings, comprising a steel pipe, wherein three wire brush plates are arranged in a circular array around the steel pipe with itself as the center, a threaded pipe is rotatably connected to the outer surface of the steel pipe, three transmission support rods are provided on the outside of the threaded pipe, a transmission plate is provided at one end of the transmission support rod, and an air inlet hood is provided at the bottom end of the steel pipe.
[0007] Furthermore, a connecting frame is fixedly installed on the outer surface of the steel pipe, and a housing is fixedly installed on the outer surface of the connecting frame. The inner wall of the housing is rotatably connected to the outer surface of the threaded pipe.
[0008] Furthermore, a storage groove is provided on the inner side of the outer casing, and a slide block is slidably connected to the inner wall of the storage groove. A movable groove is provided on the inner side of the outer casing at the location where the storage groove and the transmission support rod are located.
[0009] Furthermore, a snap-fit frame is fixedly installed on the outer surface of the slide block, and the outer surface of the wire brush plate is detachably connected to the outer surface of the snap-fit frame.
[0010] Furthermore, a limiting tube is fixedly installed on the left side of the outer shell in the storage slot, and two limiting tubes are fixedly installed on the right side of the outer shell in the storage slot. A limiting rod is slidably connected to the inner wall of the limiting tube, and the outer surface of the limiting rod penetrates the inner side of the outer shell. One end of the limiting rod is fixedly connected to the outer surface of the slide block.
[0011] Furthermore, the air intake shroud includes a drain shell, the outer surface of which is plugged into the bottom end of the steel pipe, and an expansion shell is fixedly installed on the outer surface of the drain shell. The space between the drain shell and the expansion shell is in communication with the interior of the steel pipe.
[0012] Furthermore, a rotating wheel is fixedly installed on the threaded tube above the outer shell, and a control tube is threadedly connected to the outer surface of the threaded tube. The outer surface of the control tube is rotatably connected to the transmission support rod, and the other end of the transmission support rod is rotatably connected to the outer surface of the transmission plate. The transmission plate is installed on the outer surface of the slide.
[0013] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This deburring device for metal railing processing works by using a steel pipe, a wire brush, and an air intake hood. The steel pipe extends into the railing, and an external motor drives it to rotate rapidly. During rotation, the wire brush quickly deburrs the interior of the railing. As burrs fall off and debris is generated, the airflow inside the steel pipe is rapidly drawn upwards by an external exhaust fan. Therefore, the detached burrs and debris enter the steel pipe through the air intake hood and are then discharged upwards. Furthermore, the low pressure created by the rapid air extraction inside the steel pipe allows a continuous supply of air from outside the railing to enter through both ends, thus preventing debris and burrs from flying out. This solves the problem that conventional exhaust fans cannot promptly clean the detached burrs and debris inside the railing.
[0014] This deburring device for metal railing processing works by coordinating a threaded tube, a rotating wheel, a control tube, and a transmission support rod. Rotating the rotating wheel drives the threaded tube to rotate, which in turn moves the sliding block via the transmission support rod and transmission plate. This causes the wire brush plate to extend outwards or move inwards, allowing the device to accommodate metal tubes with different inner wall diameters, thus making the design more practical.

Detailed Implementation
[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0018] Please see Figures 1 to 6This embodiment of a deburring device for metal railing processing includes a steel pipe 1. Three wire brush plates 2 are arranged in a circular array around the steel pipe 1. A threaded pipe 3 is rotatably connected to the outer surface of the steel pipe 1. Three transmission rods 4 are arranged outside the threaded pipe 3. A transmission plate 5 is provided at one end of each transmission rod 4. An air inlet hood 6 is provided at the bottom end of the steel pipe 1. A high-speed rotary joint is installed at the top end of the steel pipe 1 and connected to a hose or corrugated pipe, allowing it to connect to an exhaust fan. This causes the airflow inside the steel pipe 1 to flow rapidly upwards. Furthermore, teeth are arranged around the outer surface of the steel pipe 1 near the top end, and power transmission is achieved through the teeth and gears with the output end of a motor. During deburring, steel pipe 1 can be inserted into the interior of the railing, and then an external motor drives steel pipe 1 to rotate rapidly. During rotation, the steel wire brush 2 can quickly deburr the interior of the railing. During the process of burrs falling off and debris being generated, the airflow inside steel pipe 1 is quickly drawn upward by the external exhaust fan. Therefore, the fallen burrs and debris will enter steel pipe 1 through air intake hood 6 and be discharged upward. Furthermore, the low pressure created by the rapid air extraction inside steel pipe 1 allows air from outside the railing to continuously enter through both ends of the railing, thereby preventing debris and burrs from flying out and solving the problem that conventional exhaust fans cannot clean up the debris and burrs that fall off inside the railing in a timely manner.
[0019] A connecting frame 7 is fixedly installed on the outer surface of the steel pipe 1, and a housing 8 is fixedly installed on the outer surface of the connecting frame 7. The inner wall of the housing 8 is rotatably connected to the outer surface of the threaded pipe 3. Since the housing 8 is separated from the steel pipe 1 by the threaded pipe 3, the steel pipe 1 can drive the housing 8 to rotate through the connecting frame 7 when it rotates, so as to avoid the phenomenon of transmission failure. Furthermore, a bearing is installed inside the housing 8, and the bearing is sleeved on the threaded pipe 3, so that the threaded rod can rotate freely on the inner wall of the housing 8.
[0020] The inner side of the outer casing 8 is provided with a storage groove 9, and a slide block 10 is slidably connected to the inner wall of the storage groove 9. The inner side of the outer casing 8 at the location of the storage groove 9 and the transmission support rod 4 is provided with a movable groove 11. The storage groove 9 can provide reserved space for the movement of the slide block 10, so that the slide block 10 can be put into the interior of the outer casing 8 to reduce the width of the overall equipment. The movable groove 11 can provide the necessary space for the movement of the transmission support rod 4.
[0021] A snap-fit frame 12 is fixedly installed on the outer surface of the slide 10. The outer surface of the wire brush 2 is detachably connected to the outer surface of the snap-fit frame 12. When replacing the wire brush 2, it can be connected to the slide 10 by sliding it into the snap-fit frame 12.
[0022] A limiting tube 13 is fixedly installed on the left side of the housing 8 located in the storage slot 9. Two limiting tubes 13 are fixedly installed on the right side of the housing 8 located in the storage slot 9. A limiting rod 14 is slidably connected to the inner wall of the limiting tube 13. The outer surface of the limiting rod 14 penetrates the inner side of the housing 8. One end of the limiting rod 14 is fixedly connected to the outer surface of the slide block 10. When the slide block 10 moves, it can drive the limiting rod 14 to slide inside the limiting tube 13. The limiting rod 14 is restricted by the change in the inner wall diameter of the limiting tube 13, which can provide the maximum movement restriction for the limiting rod 14 and the slide block 10, and prevent the slide block 10 from falling out of the inside of the housing 8.
[0023] The air intake shroud 6 includes a guide shell 601. The outer surface of the guide shell 601 is plugged into the bottom end of the steel pipe 1. An expansion shell 602 is fixedly installed on the outer surface of the guide shell 601. The space between the guide shell 601 and the expansion shell 602 is interconnected with the interior of the steel pipe 1. An annular and narrow gap is left between the guide shell 601 and the expansion shell 602, which increases the air velocity in this area to better collect nearby debris.
[0024] A rotating wheel 15 is fixedly installed on the threaded tube 3 above the outer casing 8. A control tube 16 is threadedly connected to the outer surface of the threaded tube 3. The outer surface of the control tube 16 is rotatably connected to the transmission support rod 4. The other end of the transmission support rod 4 is rotatably connected to the outer surface of the transmission plate 5. The transmission plate 5 is installed on the outer surface of the slide 10. When the rotating wheel 15 is rotated, the threaded tube 3 can be driven to rotate. When the threaded tube 3 rotates, it can drive the slide 10 to move through the transmission support rod 4 and the transmission plate 5, so that the wire brush plate 2 extends outward or moves inward. This allows the device to be compatible with metal tubes with different inner wall diameters, making the design more practical.
