Abstract
Description
Technical Field
[0001] This application relates to the field of metal wire peeling technology, and more particularly to a mechanical peeling device for wire rod oxide scale. Background Technology
[0002] After hot rolling, wire rod (steel wire) often develops an unavoidable oxide scale on its surface. This oxide scale is an obstacle that must be removed in subsequent steel wire product manufacturing processes. Therefore, the oxide scale on the surface of the steel wire must be effectively removed before it enters the drawing process.
[0003] Currently, rust removal methods for metal wire mainly rely on two approaches: chemical pickling and mechanical peeling. Chemical pickling removes the oxide layer by reacting a specific acid with the oxide scale. However, this process presents significant environmental and health risks. Improperly handled chemical solutions can easily damage the ecosystem; for example, flowing into rivers can pollute water sources, and seeping into groundwater can compromise water quality. Furthermore, workers exposed to harmful chemicals in long-term pickling operations face serious health threats.
[0004] In contrast, while mechanical shelling devices avoid the contamination problems of chemical solutions, their designs are often overly complex and lack stability in practical applications, resulting in unsatisfactory shelling effects. The complex mechanical structure not only increases maintenance costs but may also lead to a higher failure rate during the shelling process, thus affecting production efficiency. Utility Model Content
[0005] The purpose of this application is to provide a mechanical descaling device for wire rod, which solves the problems of significant environmental pollution from chemical pickling during the removal of wire rod oxide scale in the prior art, and the complexity and poor descaling effect of mechanical descaling equipment.
[0006] To achieve the above objectives / to solve the above technical problems, this application adopts the following technical solution:
[0007] On one hand, this application provides a mechanical descaling device for wire rod, comprising: a support and a bracket disposed on the support; the bracket is provided with a first descaling wheel and a second descaling wheel arranged perpendicularly to each other, a limiting nozzle is horizontally disposed on one side of the first descaling wheel, the limiting nozzle is used to guide the wire rod into the first descaling wheel, and the second descaling wheel and the limiting nozzle are located on the same side of the first descaling wheel.
[0008] The support base serves as the foundation for the entire device, ensuring a stable and reliable peeling process. The bracket is used to install and support the peeling wheel and other key components. In use, the wire rod first enters the first peeling wheel through the limiting nozzle and bends around it. At this time, the oxide scale on the two opposite sides of the wire rod in the bending direction peels off. Subsequently, the wire rod enters the second peeling wheel, which is perpendicular to the first peeling wheel, and bends again in a direction perpendicular to the first peeling wheel. Through this series of bending and peeling operations, the wire rod is bent in two vertical planes, greatly improving peeling efficiency.
[0009] Optionally, when the wire rod to be peeled is located between the limiting nozzle and the first peeling wheel, it is parallel to the wire rod when it is located between the first peeling wheel and the second peeling wheel. In this state, the wire rod can be bent 180 degrees on the first peeling wheel. This achieves the best peeling effect on this plane and improves peeling efficiency.
[0010] Optionally, the device also includes a straightener, which is disposed at the wire exit end of the wire rod. Straightness is one of the important indicators for measuring the quality of wire rod. The straightener is used to correct any bending or deformation that may occur during the stripping process of the wire rod, ensuring that the wire rod remains straight at the wire exit end.
[0011] Optionally, when the wire rod to be shelled is located between the first and second shelling wheels, it is parallel to the wire rod when it is located between the second shelling wheel and the straightener. In this state, the wire rod can be bent 180 degrees by the second shelling wheel. This achieves the best shelling effect on this plane and improves shelling efficiency.
[0012] Optionally, a third stripping wheel is provided between the limiting nozzle and the first stripping wheel, and the wire rod passes through the bottom end of the third stripping wheel into the first stripping wheel. The third stripping wheel ensures that the wire rod can smoothly transition from the limiting nozzle to the second stripping wheel, avoiding wire rod wobbling and subsequent stripping.
[0013] Optionally, there are two limiting nozzles, coaxially arranged, with a stabilizing wheel between them. This ensures that the wire rod maintains a stable path before entering the peeling area, thereby reducing the wire rod's offset and sway during the peeling process.
[0014] Optionally, the support top is equipped with an openable and closable protective cover. This openable and closable design facilitates routine maintenance and repair of the equipment. During the stripping process, the wire rod may break due to excessive force or material defects. To prevent injury from flying debris caused by broken wire rod, the protective cover should be closed. Furthermore, the device contains multiple rotating components, such as stripping wheels and stabilizing wheels. The rotation of these components during equipment operation may pose a hazard. The protective cover isolates these rotating components from operators, reducing the risk of injury from accidental contact or proximity.
[0015] In addition, the oxide scale removal process generates a certain amount of dust and residue. If this dust and residue spills out uncontrolled, it will not only pollute the environment but may also pose a threat to the health of operators. A tightly closed protective cover can effectively prevent the splashing of dust and residue, maintaining a clean and safe working environment.
[0016] Optionally, a tray is provided on one side of the support, located below the peeling assembly, for collecting the detached oxide scale. The tray ensures that the detached oxide scale is collected promptly and accurately, preventing scattering and omission. This reduces cleaning workload and potential contamination risks.
[0017] Compared with existing technologies, the beneficial effects achieved by this application are as follows: This device has a simple structure. The wire rod enters the first peeling wheel through the limiting nozzle and bends around it. At this time, the oxide scale on the two opposite sides of the wire rod in the bending direction is peeled off. Subsequently, the wire rod enters the second peeling wheel, which is perpendicular to the first peeling wheel, and bends again in a direction perpendicular to the first peeling wheel. Through this series of bending and peeling operations, the wire rod is bent in two perpendicular directions, greatly improving the peeling efficiency.
[0018] In addition, this device uses a stabilizing wheel and a third peeling wheel to ensure that the wire rod can smoothly transition from the limiting nozzle to the first peeling wheel, avoiding problems such as jamming and wheel detachment caused by wire rod shaking, thus ensuring the stability and consistency of peeling quality.

[0024] The technical solutions in 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 disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.
[0025] Example 1
[0026] This embodiment describes a mechanical peeling device for wire rod oxide scale, referencing... Figure 1 and Figure 2 The mechanical descaling device for wire rod in this embodiment includes a support 1 and a bracket 2 mounted on the support 1. The support 1 serves as the foundation for the entire device, ensuring a stable and reliable descaling process. The bracket 2 is used to install and support the descaling wheels and other key components. The bracket 2 is equipped with a first descaling wheel 3 and a second descaling wheel 4 arranged perpendicularly to each other. A limiting nozzle 5 is horizontally mounted on one side of the first descaling wheel 3, guiding the wire rod into the first descaling wheel 3. The second descaling wheel 4 and the limiting nozzle 5 are located on the same side of the first descaling wheel 3.
[0027] In this embodiment, the wire rod first enters the first stripping wheel 3 through the limiting nozzle 5 and bends around it. At this time, the oxide scale on the two opposite sides of the wire rod in the bending direction peels off. Subsequently, the wire rod enters the second stripping wheel 4, which is perpendicular to the first stripping wheel 3, and bends again in a direction perpendicular to the first stripping wheel 3. Through this series of bending and stripping operations, the wire rod is bent in two perpendicular bending directions, that is, on all four sides, which greatly improves the oxide scale stripping efficiency.
[0028] This implementation also includes a straightener 6, which is installed at the wire exit end of the wire rod. Straightness is one of the important indicators for measuring the quality of wire rod. The straightener 6 is used to correct the bending or deformation that may occur in the wire rod during the stripping process, ensuring that the wire rod remains straight at the wire exit end.
[0029] In this embodiment, a third stripping wheel is provided between the limiting nozzle 5 and the first stripping wheel. The wire rod passes through the bottom end of the third stripping wheel and enters the first stripping wheel. The third stripping wheel 7 ensures that the wire rod can smoothly transition from the limiting nozzle 5 to the second stripping wheel 4, avoiding wire rod wobbling and subsequent wheel slippage.
[0030] In this embodiment, there are two limiting nozzles 5, which are coaxially arranged and a stabilizing wheel 8 is provided between them. This embodiment ensures that the wire rod maintains a stable path before entering the peeling area, thereby reducing the offset and swaying of the wire rod during the peeling process.
[0031] To ensure operator safety during equipment operation, in this embodiment, the top of the support 1 is equipped with an openable and closable protective cover 9. This openable and closable design facilitates daily maintenance and repair of the equipment. During equipment operation, the protective cover 9 should remain tightly closed. During the descaling process, the wire rod may suddenly break due to excessive force or material issues. If the protective cover 9 is closed, it will effectively prevent the broken wire rod fragments from splashing, thus avoiding injury to the operator. Furthermore, the device includes multiple rotating components, such as the descaling wheel and stabilizing wheel 8. The rotation of these components during equipment operation may pose a hazard. The presence of the protective cover 9 isolates these rotating components from the operator, reducing the risk of injury from accidental contact or proximity. In addition, a certain amount of dust and residue is generated during the descaling process. If this dust and residue splashes out uncontrollably, it will not only pollute the environment but may also pose a threat to the health of the operator. The tight closure of the protective cover 9 effectively prevents the splashing of dust and residue, maintaining a clean and safe working environment.
[0032] To prevent the detached oxide scale from scattering and being missed, thus reducing cleaning workload and potential contamination risks, in this embodiment, a tray 10 is provided on one side of the support 1. The tray 10 is located below the peeling assembly and is used to collect the detached oxide scale.
[0033] Example 2:
[0034] Based on the same inventive concept as Embodiment 1, refer to Figure 1 and Figure 2 The mechanical descaling device for wire rod in this embodiment includes a support 1 and a bracket 2 mounted on the support 1. The bracket 2 has a first descaling wheel 3 and a second descaling wheel 4 arranged perpendicularly to each other. A limiting nozzle 5 is horizontally mounted on one side of the first descaling wheel 3 to guide the wire rod into the first descaling wheel 3. The second descaling wheel 4 and the limiting nozzle 5 are located on the same side of the first descaling wheel 4. This embodiment also includes a straightener 6, which is located at the wire rod exit end. Straightness is one of the important indicators for measuring wire rod quality. The straightener 6 is used to correct any bending or deformation that may occur during the descaling process, ensuring that the wire rod remains straight at the exit end.
[0035] In this embodiment, when the wire rod to be shelled is located between the limiting nozzle 5 and the first shelling wheel 3, it is parallel to the wire rod when it is located between the first shelling wheel 3 and the second shelling wheel 4. In this state, the wire rod can be bent 180 degrees on the first shelling wheel 3, thereby achieving the best shelling effect on this plane and improving shelling efficiency. Furthermore, when the wire rod to be shelled is located between the first shelling wheel 3 and the second shelling wheel 4, it is parallel to the wire rod when it is located between the second shelling wheel 4 and the straightener 6. In this state, the wire rod can be bent 180 degrees on the second shelling wheel 4, thereby achieving the best shelling effect on this plane and improving shelling efficiency.
[0036] In this embodiment, the wire rod first enters the first stripping wheel 3 through the limiting nozzle 5 and bends 180 degrees around the first stripping wheel 3. At this time, the oxide scale on the two opposite sides of the wire rod in the bending direction peels off. Subsequently, the wire rod enters the second stripping wheel 4, which is perpendicular to the first stripping wheel 3, and bends again 180 degrees in a direction perpendicular to the first stripping wheel 3. Through two large-amplitude bends, the oxide scale on the surface of the wire rod can be peeled off more efficiently, greatly improving the oxide scale peeling efficiency.
[0037] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
