Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal parts processing technology, and in particular relates to a rust removal device for metal material processing. Background Technology
[0002] Metallic materials refer to the general term for materials with metallic properties, which are mainly composed of metallic elements or metallic elements. They include pure metals, alloys, intermetallic compounds, and special metallic materials. Most metallic materials will rust after being exposed to air for a long time. Metal pipes are a type of metallic material, so they will also rust. Therefore, rust removal work needs to be carried out on metal pipes and joints before use.
[0003] Utility model patent CN221869438U discloses a rust removal device for metal material processing, comprising a bottom shell and a connecting shell connected to its top, and further comprising: a filter plate fixed above the inner cavity of the connecting shell, the filter plate being used to receive parts requiring rust removal, and a limiting mechanism for fixing the parts being fixed below the inner cavity of the connecting shell; this utility model, through the cooperation of the limiting mechanism, can clamp parts from both inside and outside, and with the cooperation of the rust removal mechanism, can quickly switch between internal and external rust removal of parts, thereby effectively improving the applicability of the device, and making the switching between internal and external rust removal more convenient, thus improving the rust removal efficiency of parts. Simultaneously, with the cooperation of the collection mechanism, it can also uniformly collect the debris generated during the rust removal process, reducing the impact of debris on the surrounding environment, and solving the problems of poor applicability and inefficient rust removal of current devices.
[0004] However, the above-mentioned device has the following technical problems in actual use:
[0005] 1. In actual use, the above-mentioned device moves the outer or inner rust-removing shell sequentially to the output end of the stepper motor by sliding the movable plate. The rotation of the stepper motor output end controls the rotation of the outer and inner rust-removing shells to remove rust from the end of the metal pipe. However, the outer and inner rust-removing shells in the above-mentioned device can only be controlled individually (i.e., external rust removal is performed on the end of the metal pipe before internal rust removal), and cannot be driven to rotate simultaneously. This results in a longer rust removal time and reduced efficiency.
[0006] Second, the dimensions of the outer and inner rust-removing shells of the aforementioned device cannot be adjusted, which means that the device can only remove rust from metal pipes of a specific diameter, thus limiting its application scenarios. Utility Model Content
[0007] This utility model provides a rust removal device for metal material processing, which aims to solve the problem mentioned in the background art that the above-mentioned device can only perform external rust removal on the metal pipe and then perform internal rust removal, and cannot perform simultaneous rust removal on the inner and outer walls of the metal pipe at the same time, which reduces the rust removal efficiency. At the same time, the size of the outer rust removal shell and the inner rust removal shell of the above-mentioned device cannot be adjusted, and can only meet the rust removal needs of metal pipes with a specific diameter.
[0008] This utility model is implemented as follows: a rust removal device for metal material processing includes: a collection box with a fixed cylinder fixed to its top, a metal pipe to be processed vertically inserted inside the fixed cylinder; a lifting bracket fixedly installed on one side wall of the collection box, and a rotating motor fixedly connected to the top of the lifting bracket; a rotating plate fixedly installed on the output end of the rotating motor; the rotating plate is horizontally arranged and has a rust removal mechanism; the rust removal mechanism has: a first rust removal component and a second rust removal component respectively disposed at both ends of the rotating plate; the first rust removal component is used to remove rust from the inner peripheral wall of the metal pipe. Furthermore, the second rust removal component is used to remove rust from the outer peripheral wall of the metal pipe fitting. In this scheme, after the metal pipe fitting is placed in the fixed cylinder, the positions of the first and second rust removal components are manually adjusted so that the first rust removal component fits against the inner peripheral wall of the metal pipe fitting, and the second rust removal component fits against the outer peripheral wall of the metal pipe fitting. Subsequently, when the output end of the rotating motor drives the rotating plate to rotate, the rotating plate can simultaneously drive the first and second rust removal components to rotate, thereby using the first and second rust removal components to remove rust from the inner and outer peripheral walls of the end of the metal pipe fitting at the same time, effectively improving the working efficiency of the device.
[0009] Furthermore, in this device, the first electric actuator can control the first sliding seat to slide in the first slide groove, and the second electric actuator can control the second sliding seat to slide in the second slide groove. By adjusting the positions of the first and second sliding seats, this device can attach the first and second rust-removing rollers to the surfaces of metal pipes of different diameters that need rust removal, thus expanding the application scenarios of this device.
[0010] Preferably, the lifting bracket includes: a fixed base fixedly installed on the side wall of the collection box; a receiving groove is formed on the top wall of the fixed base; a connecting bracket is movably installed in the receiving groove; the connecting bracket has: a vertical part erected in the receiving groove; a horizontal part fixedly installed at the top of the vertical part; the horizontal part and the vertical part are perpendicular to each other; a rotating motor is fixedly installed on the horizontal part; and a driving assembly connected to the vertical part is also provided on the side wall of the fixed base; the driving assembly has: a first connecting seat fixedly connected to the side wall of the fixed base, and the... A second connecting seat is fixedly installed on the side wall of the vertical part, and a first electric actuator is fixedly connected to the bottom wall of the first connecting seat, with its output end fixedly connected to the second connecting seat. In this scheme, the vertical part is inserted into the receiving groove and slidably connected to the receiving groove. When the output end of the electric actuator extends, it pushes the second connecting seat to move away from the first connecting seat. At the same time, the second connecting seat drives the vertical part to extend out of the receiving groove, thereby adjusting the height of the horizontal part (the distance between it and the fixed cylinder). Conversely, when the output end of the electric actuator retracts, it pulls the vertical part to retract into the receiving groove, thereby reducing the height of the horizontal part.
[0011] Preferably, the first rust removal component includes: a first sliding groove formed on one end of the rotating plate, a first sliding seat slidably installed in the first sliding groove, a first electric push rod fixedly connected to the end of the rotating plate, the output end of the first electric push rod fixedly connected to the side wall of the first sliding seat, a first rotating groove formed on the side wall of the first sliding seat, a first rotating shaft rotatably arranged in the first rotating groove, a first rust removal roller fixedly connected to the outside of the first rotating shaft, and a first drive motor fixedly connected to the top wall of the first sliding seat, the output end of which is fixedly connected to the end of the first rotating shaft. In this scheme, the first sliding seat is moved in the first sliding groove by the extension and retraction of the output end of the first electric push rod, thereby adjusting the horizontal position of the first sliding seat. Then, the output end of the first drive motor controls the rotation of the first rotating shaft, thereby controlling the rotation of the first rust removal roller. The first rust removal roller adheres to the inner peripheral wall of the metal pipe and removes the rust on the inner peripheral wall of the metal pipe.
[0012] Preferably, the second rust removal component includes: a second sliding groove formed on one end of the rotating plate, a second sliding seat slidably installed in the second sliding groove, a second electric push rod fixedly connected to the end of the rotating plate, the output end of the second electric push rod fixedly connected to the side wall of the second sliding seat, a second rotating groove formed on the side wall of the second sliding seat, a second rotating shaft rotatably arranged in the second rotating groove, a second rust removal roller fixedly connected to the outside of the second rotating shaft, and a second drive motor fixedly connected to the top wall of the second sliding seat, the output end of which is fixedly connected to the end of the second rotating shaft. In this scheme, the second sliding seat is moved in the second sliding groove by the extension and retraction of the output end of the second electric push rod, thereby adjusting the horizontal position of the second sliding seat. Then, the output end of the second drive motor controls the rotation of the second rotating shaft, thereby controlling the rotation of the second rust removal roller. The second rust removal roller adheres to the outer peripheral wall of the metal pipe and removes the rust on the outer peripheral wall of the metal pipe.
[0013] Preferably, the collection box has a collection cavity inside, and a discharge trough communicating with the collection cavity is opened on the top wall of the collection box inside the fixed cylinder. A support plate is also horizontally arranged inside the fixed cylinder. The support plate is used to support the metal pipe to be processed, and several waste discharge holes are opened on the support plate. In this scheme, the metal pipe is placed on the support plate. When the first rust removal component and the second rust removal component perform rust removal treatment on the inner and outer peripheral walls of the end of the metal pipe, some metal debris will fall off. This metal debris will fall into the discharge trough through the waste discharge holes opened on the support plate, and then enter the collection cavity for storage, which is convenient for subsequent unified processing.
[0014] Preferably, the support plate has multiple clamping grooves at equal angles, and each clamping groove is slidably connected to a clamping plate. The top of the clamping plate is attached to the outer wall of the metal pipe. The inner wall of the fixed cylinder is provided with a push cylinder corresponding to the multiple clamping plates. The output end of each push cylinder is fixedly connected to the side wall of the clamping plate on the corresponding side. In this scheme, when the metal pipe is placed vertically on the support plate, the end of the metal pipe is between the multiple clamping plates. Then, the output ends of the multiple push cylinders extend simultaneously to push the clamping plates to adhere to the outer wall of the metal pipe, clamping and limiting the metal pipe, preventing the metal pipe from shaking or tipping over during subsequent grinding.
[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a rust removal device for metal material processing.
[0016] 1. After the metal pipe is placed in the fixed cylinder, the positions of the first and second rust removal components are manually adjusted so that the first rust removal component is in contact with the inner circumferential wall of the metal pipe and the second rust removal component is in contact with the outer circumferential wall of the metal pipe. Subsequently, when the output end of the rotating motor drives the rotating plate to rotate, the rotating plate can simultaneously drive the first and second rust removal components to rotate. Thus, the first and second rust removal components can be used to remove rust from the inner and outer circumferential walls of the end of the metal pipe at the same time, which effectively improves the working efficiency of the device.
[0017] 2. In this device, the first electric push rod can control the first sliding seat to slide in the first slide groove, and the second electric push rod can control the second sliding seat to slide in the second slide groove. By adjusting the positions of the first and second sliding seats, this device can attach the first and second rust-removing rollers to the surfaces of metal pipes of different diameters that need rust removal, thus expanding the application scenarios of this device.

[0038] Specifically, in this device, the outer sides of the first rust removal roller 415 and the second rust removal roller 425 are covered with sandpaper.

[0046] Next, the output of the rotating motor 3 controls the rotating plate 31 to rotate, the output of the first drive motor 416 controls the first rust removal roller 415 to rotate, and the output of the second drive motor 426 controls the second rust removal roller 425 to rotate.
