Description

rust removal mechanism for bar stock surface Technical Field

[0001] This utility model relates to the field of bar stock processing technology, and in particular to a rust removal mechanism for bar stock surfaces. Background Technology

[0002] A rust removal system is a device or technical apparatus used to remove rust, oxide layers or other contaminants from the surface of metal bars, such as steel bars, copper bars, and aluminum bars, with the aim of restoring the cleanliness and smoothness of the material surface or providing a qualified surface condition for subsequent processing.

[0003] In existing technologies, most general rust removal mechanisms rely on the friction between a high-speed rotating grinding wheel and the surface of the bar stock to achieve rust removal. However, these mechanisms lack effective dust removal capabilities. During the rust removal process, a large amount of metal powder is generated. Without effective dust removal measures, this powder floats directly in the air, causing serious pollution to the surrounding working environment. This results in a pungent metallic odor and fine particulate matter filling the air, affecting the air quality of the entire work area. Furthermore, prolonged exposure to such an environment poses a significant health hazard to operators. Therefore, it is necessary to improve the bar stock surface rust removal mechanism to solve the above problems. Summary of the Invention

[0004] Without effective dust removal measures, these powders float directly in the air, causing serious pollution to the surrounding working environment.

[0005] The technical solution of this utility model is as follows: a rust removal mechanism for bar stock, including a base plate and a guide rail fixedly connected to the top of the base plate. A bar stock body to be polished is set on the guide rail. A first support frame is fixedly connected to the top of the base plate. A first rotating shaft is rotatably connected to the first support frame. An auxiliary roller is fixedly connected to the first rotating shaft. A second support frame is fixedly connected to the top of the base plate. A dust collection hood is fixedly connected to the second support frame. An air supply pipe is fixedly connected to the dust collection hood. An air pump connected to the air supply pipe is fixedly connected to the top of the base plate. A rust removal component is set on the top of the base plate. A power component is set on the top of the base plate. The power component provides power to rotate the auxiliary roller to cooperate with the rust removal component to remove rust from the bar stock body. At the same time, the air pump sucks up the dust generated during rust removal through the air supply pipe and the dust collection hood.

[0006] Preferably, a protective net is fixedly connected to the dust collection hood, a dustproof net is fixedly connected to the air supply pipe, a closed door is rotatably connected to the dust collection hood, and a positioning plate connected to the dust collection hood is fixedly connected to the closed door, so that the closed door is positioned in the closed state by the positioning plate.

[0007] Preferably, the rust removal assembly includes a third support frame fixedly connected to the top of the base plate, a second rotating shaft rotatably connected to the third support frame, a wire roller disposed on the second rotating shaft, and bolts threadedly connected to the second rotating shaft.

[0008] Preferably, the guide rail is inclined, which allows the bar stock to move radially along the auxiliary roller and the wire roller.

[0009] Preferably, the bolt contacts the wire roller, and the position of the wire roller on the second rotating shaft is fixed by the bolt.

[0010] Preferably, the power assembly includes a positioning seat fixedly connected to the top of the base plate, a motor fixedly connected to the top of the base plate, a third rotating shaft fixedly connected to the output end of the motor, a first pulley fixedly connected to the third rotating shaft, a second pulley fixedly connected to the third rotating shaft, a third pulley fixedly connected to the second rotating shaft, a fourth pulley fixedly connected to the first rotating shaft, a first synchronous belt drivingly connected between the first pulley and the third pulley, and a second synchronous belt drivingly connected between the second pulley and the fourth pulley.

[0012] The beneficial effects of this utility model are:

[0013] 1. The air pump, in conjunction with the dust hood, generates a strong suction force, thereby drawing air containing metal powder into the dust hood while removing rust. This timely extraction of metal dust effectively prevents the dust from spreading in the air, thus avoiding environmental pollution and inhalation by the human body.

[0014] 2. The size of the wire roller can be changed according to the actual application, or different sizes and types of grinding rollers can be used to meet different grinding and rust removal tasks, making it more widely applicable and flexible and convenient to use.

[0015] 3. The first and second rotating shafts can be operated at different speeds while the motor rotation remains constant. Furthermore, the fourth and third pulleys of different sizes can be replaced as needed to control the speed of the first and second rotating shafts and meet various rust removal requirements.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to Figures 1-7. This utility model provides an embodiment of a bar stock surface rust removal mechanism, including a base plate 1 and a guide rail 5 fixedly connected to the top of the base plate 1. A bar stock body 6 to be polished is mounted on the guide rail 5. A first support frame 21 is fixedly connected to the top of the base plate 1, a first rotating shaft 22 is rotatably connected to the first support frame 21, and an auxiliary roller 23 is fixedly connected to the first rotating shaft 22. A second support frame 24 is fixedly connected to the top of the base plate 1, a dust suction hood 25 is fixedly connected to the second support frame 24, an air supply pipe 26 is fixedly connected to the dust suction hood 25, and an air pump 27 connected to the air supply pipe 26 is fixedly connected to the top of the base plate 1. A rust removal component is mounted on the top of the base plate 1, and a power component is mounted on the top of the base plate 1. The power component provides power to rotate the auxiliary roller 23 to cooperate with the rust removal component to remove rust from the bar stock body 6. At the same time, the air pump 27 sucks up the dust generated during rust removal through the air supply pipe 26 and the dust suction hood 25. The power component drives the first rotating shaft 22 to rotate, and the first rotating shaft 22 drives the auxiliary roller 23 to rotate. At the same time, the power component also starts the rust removal process synchronously. The bar stock body 6 moves radially along the auxiliary roller 23 as it rotates on the guide rail 5. Then, it cooperates with the rust removal component to remove rust. The air pump 27 draws air from around the bar stock body 6 through the air supply pipe 26 and the dust suction hood 25, sucking the air with metal dust into the dust suction hood 25 to prevent the metal dust from spreading everywhere.

[0026] Please refer to Figures 2, 3, and 4. In this embodiment, a protective net 28 is fixedly connected to the dust collection hood 25, a dustproof net 29 is fixedly connected to the air supply pipe 26, and a sealing door 210 is rotatably connected to the dust collection hood 25. A positioning plate 211 connected to the dust collection hood 25 is fixedly connected to the sealing door 210. The sealing door 210 is positioned in the closed state by the positioning plate 211. The positioning plate 211 can be connected to the dust collection hood 25 by bolts. The bolts can be replaced with other connection methods as needed to position the sealing door 210. Opening the sealing door 210 can clean the metal powder inside the dust collection hood 25 and ensure the normal use of the device.

[0027] Please refer to Figures 1 and 5-7. In this embodiment, the rust removal assembly includes a third support frame 31 fixedly connected to the top of the base plate 1, a second rotating shaft 32 rotatably connected to the third support frame 31, a wire roller 33 mounted on the second rotating shaft 32, and a bolt 34 threadedly connected to the second rotating shaft 32. The high-speed rotating wire roller 33 is applied to different bar stock bodies 6, such as bar stock bodies 6 with threaded grooves on their surface. The wires of the wire roller 33 can extend into the threaded grooves to treat the rust inside the threaded grooves. The wire roller 33 can be replaced as needed. Grinding rollers of different sizes and types are provided. The guide rail 5 is inclined, which allows the bar body 6 to move radially along the auxiliary roller 23 and the wire roller 33. The inclined guide rail 5 can slide while the bar body 6 rotates, so that the bar body 6 moves automatically and removes rust from the bar body 6 in all directions. The bolt 34 contacts the wire roller 33 and fixes the position of the wire roller 33 on the second rotating shaft 32. The bolt 34 positions the wire roller 33, so that the wire roller 33 can be flexibly replaced to meet different grinding needs.

[0028] Please refer to Figures 1 and 6. In this embodiment, the power assembly includes a positioning seat 41 fixedly connected to the top of the base plate 1, a motor 42 fixedly connected to the top of the base plate 1, a third rotating shaft 49 fixedly connected to the output end of the motor 42, a first pulley 43 fixedly connected to the third rotating shaft 49, a second pulley 44 fixedly connected to the third rotating shaft 49, a third pulley 45 fixedly connected to the second rotating shaft 32, a fourth pulley 46 fixedly connected to the first rotating shaft 22, a first synchronous belt 47 drivingly connecting the first pulley 43 and the third pulley 45, and a second synchronous belt drivingly connecting the second pulley 44 and the fourth pulley 46. 48. The auxiliary roller 23 and the wire roller 33 rotate synchronously, but at different speeds and in different directions. The auxiliary roller 23 rotates slowly only to make the bar body 6 rotate and move. The high-speed rotation of the wire roller 33 can effectively remove the rust on the surface. The first pulley 43, the second pulley 44, and the third pulley 45 are the same size. The fourth pulley 46 is larger than the first pulley 43, the second pulley 44, and the third pulley 45. With the speed of the motor 42 remaining constant, the first rotating shaft 22 and the second rotating shaft 32 have different speeds. The fourth pulley 46 and the third pulley 45 of different sizes can be replaced as needed to control the speed of the first rotating shaft 22 and the second rotating shaft 32.

[0029] During operation, the bar stock 6 is placed on the guide rail 5. The motor 42 is started, driving the third rotating shaft 49. The third rotating shaft 49 drives the second pulley 44, which in turn drives the fourth pulley 46 via the second synchronous belt 48. The fourth pulley 46 drives the first rotating shaft 22, which in turn drives the auxiliary roller 23. The auxiliary roller 23 rotates and contacts the bar stock 6, causing the bar stock 6 to rotate and slide on the guide rail 5. Simultaneously, the third rotating shaft 49 rotates, driving the first pulley 43. The first pulley 43, via the first synchronous belt 47, drives the third pulley 45, which in turn drives the second rotating shaft 32. The second rotating shaft 32 drives the wire roller 33, which rotates and contacts the bar stock 6, thus performing rust removal. Simultaneously, the air pump 27 is started during rust removal. Air is drawn from inside the dust collection hood 25 through the air supply pipe 26, causing the dust collection hood 25 to draw in outside air through the protective net 28. The air containing metal dust generated during rust removal is sucked into the dust collection hood 25 and filtered through the dustproof net 29, leaving the dust inside the dust collection hood 25. After rust removal is completed, the positioning plate 211 is released, and the closed door 210 is opened, allowing manual cleaning of the accumulated metal powder inside the dust collection hood 25. When the device is not in use, the bolt 34 is unscrewed to release the positioning of the bolt 34 on the wire roller 33, allowing the wire roller 33 to be replaced.

[0030] Through the above steps, air containing metal powder is drawn into the dust hood 25 while rust removal is being carried out, and the metal dust is extracted in time. This effectively prevents the metal dust from drifting in the air, thus solving the problem that without effective dust removal measures, the powder would float directly in the air, which would cause serious pollution to the surrounding working environment.
