Description
Technical Field
[0001] This utility model belongs to the technical field of steel bar processing equipment, and more specifically, it relates to a rust removal device for steel bar production. Background Technology
[0002] Reinforcing steel refers to steel used in reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, sometimes square with rounded corners. It is classified by type into plain round steel bars, ribbed steel bars, and twisted steel bars. There are various materials used for reinforcing steel, but carbon steel is the most widely used in construction. Its main components are carbon and iron, but this material makes it very prone to rusting.
[0003] In building construction, rust on reinforcing steel has a significant negative impact on concrete pouring. For example, it reduces the mechanical properties of the steel, leading to structural damage and affecting structural durability. Therefore, removing rust from the surface of reinforcing steel is crucial. Existing technologies include widely used rust removal techniques, such as Chinese invention patent CN115464527A, which involves inserting one end of the reinforcing steel into a rust-removing cylinder. A drive mechanism rotates the cylinder, causing cleaning components to remove rust from the steel surface. However, analysis shows that this device can only feed one reinforcing steel bar at a time, resulting in relatively low efficiency and making it unsuitable for large-scale steel processing in steel mills. Figure 1 As shown, the steel bars produced in the factory are stored using steel bar stacking racks. If the storage time is too long, rust will appear on the surface of the steel bars. In order to ensure the quality of the shipped products, the steel bars need to be derusted. Considering the characteristics of the factory's large volume and the relatively small degree of steel bar rust, traditional rust removal equipment meets the needs well, and its technical solution needs to be improved. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a rust removal device for steel bar production. Through a specially designed drum, steel bars are placed inside for rust removal. Mechanical transmission causes a large number of steel bars to rub against each other within the drum, resulting in high efficiency and speed. This solves the problem of low efficiency in existing technologies where steel bars are fed into the equipment one by one for rust removal.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a rust removal device for steel bar production, including a mounting frame, wherein a plurality of rotatable gears are provided in the mounting frame, a gear ring is installed through the plurality of gears, the plurality of gears surround and mesh with the gear ring, a drive mechanism is connected to at least one of the gears, a roller is provided in contact with the inner wall of the gear ring, and a lifting structure is provided below the mounting frame.
[0006] Optionally, the lifting structure includes a base, on which a hydraulic jack is mounted to support the mounting frame, and multiple hinged support rods are provided between the mounting frame and the base.
[0007] Optionally, the drive mechanism includes a motor, which is connected to one of the gears via a reducer.
[0008] Optionally, casters are provided under the base.
[0009] Optionally, the inner wall of the roller is provided with friction stripes.
[0010] Optionally, it may also include at least one rust-removing rod, the length of which is adapted to the length of the reinforcing bar, and the outer wall of the rust-removing rod is covered with steel wire brushes.
[0011] Optionally, it also includes at least one oiling rod, the oiling rod comprising a tube body, the tube body being closed at both ends and having a length adapted to the reinforcing steel bar, and having multiple oil outlet holes evenly opened on the tube body wall.
[0012] Optionally, the tube is covered with a fiber cloth.
[0013] Optionally, at least one end of the tube is provided with a removable sealing bolt.
[0014] Optionally, the mounting bracket is provided with a housing that covers the gear, the gear ring, and the drive mechanism.
[0015] This utility model provides a rust removal device for steel bar production, which has the following beneficial effects:
[0016] 1. By using a set roller, the steel bars are placed in the roller during rust removal. The mechanical transmission causes a large number of steel bars to rub against each other in the roller to remove rust, which is highly efficient and fast.
[0017] 2. This rust removal equipment can use a lifting structure to directly lift the steel bars on the steel bar stacking rack for rust removal. After rust removal, the steel bars can be directly put back on the steel bar stacking rack, eliminating the process of transporting steel bars and making the usage process simpler.
[0018] 3. This rust removal equipment has a simple structure, low production cost, small size, is easy to move, and is suitable for multiple scenarios. Attached Figure Description

Detailed Implementation
[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0029] This utility model provides the following technical solution:
[0030] A rust removal device for steel bar production, which is mainly used in steel bar production, such as... Figure 1 As shown, the steel bars stacked on the steel bar stacking rack 11 in the warehouse can undergo convenient and quick rust removal treatment before leaving the factory. Figures 2-4 The rust removal equipment includes a mounting frame 1, within which multiple rotatable gears 2 are mounted via bearing seats. There are more than two gears 2. Gear rings 3 are mounted on these gears 2, with the gears 2 surrounding and meshing with them. Limit structures on the gears 2 prevent the gear rings 3 from falling off. A drive mechanism 5 is connected to at least one gear 2, which, through meshing, drives the gear rings 3 to rotate. Crucially, a roller 4 is fitted against the inner wall of the gear rings 3. A lifting structure 6 is located below the mounting frame 1, which can raise the roller 4 for subsequent rust removal operations.
[0031] In implementation, such as Figure 5 As shown, at least two rust removal devices are used. Taking two as an example, the devices are placed at both ends of the stacked steel bars 8 to be rusted. The ends of the steel bars 8 are then placed into the rollers 4 of the rust removal devices. The lifting mechanism 6 is used to lift the rollers 4, suspending the steel bars 8 in the air. Then, the drive mechanism 5 is activated, causing the gear 2 to drive the gear ring 3 to rotate. This allows the steel bars 8 to rotate within the rollers 4, rubbing against each other to remove the rust. It should be noted that if the steel bars 8 are relatively soft, several rust removal devices may be needed to ensure they can be easily lifted.
[0032] The specific structure will be detailed below:
[0033] Lifting Structure 6: The structure used in this embodiment is as follows Figure 6 As shown, the system includes a base 61, on which a hydraulic jack 62 is mounted. The hydraulic jack 62 supports the mounting frame 1 and enables the lifting and lowering of the roller 4. To ensure structural stability, multiple hinged support rods 63 are installed between the mounting frame 1 and the base 61, which limit the movement of the roller 4. It should be noted that the lifting device of the hydraulic jack 62 and the structure of the multiple hinged support rods 63 are not unique and can be modified in various ways. For example, the hydraulic jack 62 can be configured as a hydraulic cylinder or an electric cylinder, etc.
[0034] To facilitate the movement of the rust removal equipment, casters 64 are provided under the base 61. The casters 64 are equipped with locking devices to secure the rust removal equipment during operation.
[0035] Drive mechanism 5: such as Figure 4 As shown, it includes a motor 51, which is connected to one of the gears 2 via a reducer 52. The motor 51 works in conjunction with the reducer 52 to achieve drive. The drive mechanism 5 can be of various types, but this embodiment only shows the one type.
[0036] Considering protection and safety, in this solution, a housing 10 is provided on the mounting frame 1. The housing 10 covers the gear 2, gear ring 3 and drive mechanism 5, isolating the internal mechanical structure from the outside world and protecting the inside. At the same time, it prevents the machine from being accidentally touched and entangled during operation.
[0037] To prevent the steel bars 8 to be derusted from sliding in the roller 4 and failing to achieve rolling and flipping, therefore... Figure 7 As shown, friction stripes 41 are provided on the inner wall of the roller 4 to increase friction.
[0038] In addition to the mutual friction of the reinforcing bars 8 for rust removal, to further enhance the rust removal effect, such as... Figure 5As shown, the rust removal equipment also includes at least one rust removal rod 7, the length of which is adapted to the length of the reinforcing bar 8. The outer wall of the rust removal rod 7 is covered with wire brushes. During implementation, at least one rust removal rod 7 is placed into the bundle of the reinforcing bar 8 to be rusted. When the reinforcing bar 8 is turned over, its outer surface comes into contact with the wire brushes. Continuous turning activates the cleaning effect. The specific number of rust removal rods 7 placed depends on the number of reinforcing bars 8 to be rusted.
[0039] In addition, considering that some steel bars need to be stored for a long time or have special requirements that require oiling, such as... Figure 8 As shown, this unit is also equipped with accessories including at least one oiling rod 9. The main body of the oiling rod 9 consists of a tube 91, which is closed at both ends and its length is adapted to the reinforcing bar 8. Multiple oil outlet holes 92 are evenly opened on the wall of the tube 91. During implementation, oil is poured into the tube 91, and then at least one oiling rod 9 is placed into the reinforcing bar 8 to be oiled. When the reinforcing bar 8 is turned over, the oil is applied to the surface of the reinforcing bar 8 through the oil outlet holes 92, achieving the purpose of oiling. To ensure uniform oiling, a fiber cloth can be wrapped around the tube 91. During implementation, the oil in the tube 91 seeps out through the oil outlet holes 92, wetting the fiber cloth, which then comes into contact with the reinforcing bar 8 to be oiled. This method allows areas without oil to be contaminated, while areas with excessive oil can be absorbed by the fiber cloth, ensuring uniform oiling. The fiber cloth is used because it is wear-resistant; materials such as nylon, polyester, etc., are used.
[0040] To facilitate the addition of oil to the pipe body 91, a removable sealing bolt 93 is provided at at least one end of the pipe body 91. Oil can be added to the pipe body 91 by unscrewing the sealing bolt 93.
[0041] In summary, this rust removal equipment can directly remove rust and polish multiple steel bars stacked in the warehouse at once, eliminating the need to transport and remove rust one by one. Its efficiency is higher than that of traditional rust removal machines, and its application scenarios are more flexible. Due to its smaller size, the equipment is also more convenient to use.
