Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, specifically to a polishing device for copper processing. Background Technology

[0002] In the processing of copper rods, surface treatment using polishing equipment is necessary to remove surface burrs and improve surface finish. Belt sanders are one of the commonly used pieces of equipment in the polishing field, widely used in metal surface grinding scenarios. Their core structure includes: a power system (such as a drive motor and transmission wheel set, providing stable power for the sanding belt movement), a sanding belt (the grinding execution component, achieving polishing through high-speed motion), a machine frame (supporting all components and ensuring equipment operational stability), an operating system (including a power switch, speed control knob, etc., enabling equipment operation), and a grinding table (supporting the workpiece and assisting in precise polishing). All components work together to complete the polishing process of the metal surface.

[0003] However, most existing belt sanders are of general-purpose design. While they can adapt to the polishing needs of various metals, they have significant limitations when polishing copper parts. The physical properties of copper make it sensitive to temperature. When the local temperature exceeds 50°C during sanding, the surface of the copper part is prone to oxidation, forming dark red oxide spots. These oxide spots not only affect the processing efficiency of subsequent fine polishing processes (requiring additional removal of the oxide layer), but may also lead to substandard surface finish, failing to meet the quality requirements of high-precision copper rods.

[0004] To address this specific pain point in copper polishing, those skilled in the art have made targeted improvements to existing belt sanders to solve the problem of copper oxidation caused by high-temperature grinding, and thus proposed a dedicated polishing device suitable for copper processing scenarios. Utility Model Content

[0005] The purpose of this invention is to solve the problem of copper parts oxidation caused by high temperature during grinding, based on the existing belt sander.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A polishing device for copper processing includes a power system, a sanding belt, a machine frame, and a polishing table. A cantilever is mounted on the machine frame, and a spray head with its nozzle facing the sanding belt is mounted on the cantilever. The position of the spray head on the sanding belt is above the polishing table. The spray head is used to spray a rust inhibitor for copper.

[0008] Furthermore, a liquid supply system is installed on the side of the fuselage frame. The liquid supply system includes a box for holding copper rust inhibitor and a spray pump installed on the side wall of the box. The inlet of the spray pump is connected to an inlet pipe that extends into the box, and the outlet is connected to an outlet pipe that connects to the spray head.

[0009] Furthermore, the cantilever is L-shaped and the spray head is installed on its transverse section. The cantilever has a device hole for inserting the spray head, and the spray head is placed in the device hole and then secured by a hand-tightened bolt threaded on the side of the cantilever.

[0010] Furthermore, a dust suction hood is provided at the lateral section of the cantilever and is located above the grinding table, with the spray head located within the coverage area of ​​the dust suction hood.

[0011] Furthermore, the distance between the spray head and the sand belt is less than 2 cm.

[0012] Furthermore, fixing blocks are welded to the top two sides of the dust hood, and screw holes are provided on the fixing blocks. Bolts are installed on the side of the transverse section of the cantilever through the screw holes.

[0013] Furthermore, a flange is fixedly connected to the side of the dust collection hood, and the flange is used to connect the pipeline of the negative pressure dust collection equipment.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model sprays a copper rust inhibitor onto the sanding belt through a spray head. The rust inhibitor adheres to the surface of the sanding belt. When the sanding belt comes into contact with the copper part for grinding, the rust inhibitor absorbs the frictional heat generated by grinding and carries the heat away with the movement of the sanding belt, thus preventing the local temperature of the copper part from exceeding 50°C and thus avoiding the problem of copper oxidation.

[0016] 2. This utility model adds a liquid supply system, spray head, and dust hood to the traditional belt sander, without modifying the power system, sanding belt, or other core components, thus solving the problems of grinding dust and high-temperature oxidation of copper parts.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This embodiment provides a polishing device for copper processing, mainly based on the existing belt sander, to solve the problem of copper oxidation caused by high temperature during grinding, and provides the following technical solution, which will be combined with... Figures 1-4 Please provide a detailed explanation:

[0024] Example 1:

[0025] A polishing device for copper processing includes a power system 1, a sanding belt 2, a machine frame 3, and a polishing table 4. These structures are conventional components of existing belt sanders, and their functions and connections are well-known to those skilled in the art. The device also includes an operating system with a power switch and a speed control knob (for starting / stopping the equipment and adjusting its speed). The core improvement of this application is as follows: a cantilever 5 is fixedly mounted on the machine frame 3, and a spray head 6 with its nozzle facing the sanding belt 2 is mounted on the cantilever 5. The spray head 6 is positioned directly above the polishing table 4, above the working area of ​​the sanding belt 2 (i.e., the core area where the sanding belt 2 contacts and polishes the copper workpiece). The spray head 6 is used to directionally spray a copper rust inhibitor. Simultaneously, the distance between the spray head 6 and the sanding belt 2 is less than 2 cm. This distance design ensures that the rust inhibitor evenly covers the surface of the sanding belt 2 in a mist form, avoiding waste or uneven protection caused by dripping like water.

[0026] During operation, a copper rust inhibitor is sprayed onto the sanding belt 2 through the spray head 6. The rust inhibitor adheres to the surface of the sanding belt 2 and forms a thin protective film. When the sanding belt 2 comes into contact with the copper part for grinding, the rust inhibitor absorbs the frictional heat generated by grinding through the heat absorption properties of liquid, and carries away the heat synchronously with the movement of the sanding belt 2. This effectively controls the local temperature of the copper part below 50℃ (the critical temperature for copper oxidation), thus preventing the copper part from undergoing oxidation reaction due to high temperature from the source.

[0027] Please see Figure 1 and Figure 2To clearly define the rust inhibitor supply structure, a liquid supply system 7 is installed on the side of the machine frame 3. The liquid supply system 7 includes a tank 71 for storing copper rust inhibitor and a spray pump 72 fixed to the side wall of the tank 71. The inlet of the spray pump 72 is connected to an inlet pipe 73 that extends into the bottom of the tank 71 (ensuring that most of the rust inhibitor in the tank can be drawn), and the outlet is connected to an outlet pipe 74 for conveying the rust inhibitor. The other end of the outlet pipe 74 is sealed and connected to the spray head 6. After the spray pump 72 is started, it draws rust inhibitor from the tank 71 through the inlet pipe 73, accurately delivers it to the spray head 6 through the outlet pipe 74, and finally sprays it evenly onto the sand belt 2 from the spray head 6, thus achieving liquid supply spraying.

[0028] To illustrate the installation and adjustment of the spray head 6, the cantilever 5 is designed with an L-shaped structure, and the spray head 6 is mounted on the transverse section of the cantilever 5. The transverse section of the cantilever 5 has a device hole 51 for accommodating the spray head 6. After the spray head 6 is inserted into the device hole 51, it is secured by a hand-tightened bolt 52 threaded through the side of the cantilever 5. The operator can fine-tune the depth of the spray head 6 in the device hole 51 by loosening or tightening the hand-tightened bolt 52, thereby controlling the height of the nozzle from the abrasive belt 2 to ensure that it is compatible with the polishing requirements of different specifications of abrasive belt 2.

[0029] Example 2:

[0030] Based on Example 1, this embodiment addresses the dust problem generated during the polishing of copper parts (dust accumulation easily affects polishing accuracy, and rust inhibitor droplets mixed with dust easily contaminate the surface of the copper parts), and supplements the following technical solution:

[0031] A dust hood 8 is fitted to the transverse section of the cantilever 5, and the dust hood 8 completely covers the working area of ​​the sanding belt 2 above the sanding table 4. The spray head 6 is located inside the dust hood 8 (ensuring that the mist generated by the spray can be collected simultaneously with the sanding dust). To achieve stable fixation of the dust hood 8, fixing blocks 9 are symmetrically welded to both sides of the top of the dust hood 8. The fixing blocks 9 have screw holes 10 that are adapted to the cantilever 5. By passing bolts through the screw holes 10 and locking them into the pre-threaded holes in the transverse section of the cantilever 5, the dust hood 8 can be firmly installed on the cantilever 5, and it is easy to disassemble and clean later.

[0032] In addition, a flange 11 is integrally connected to the side of the dust hood 8. The flange 11 is used for a sealed connection with the pipeline of the negative pressure dust collection equipment (the seal is achieved by bolt locking to prevent air leakage from affecting the dust collection effect). During operation, after the negative pressure dust collection equipment is started, a low-pressure area will be formed inside the dust hood 8. The mixture of copper powder and rust inhibitor droplets generated during the polishing process will be sucked into the dust hood 8 under the action of the internal and external air pressure difference, and then transported to the dust collection box of the negative pressure equipment through the connecting pipeline to achieve clean treatment of the polishing area.

[0033] The advantages of this embodiment are that it only requires the addition of a liquid supply system 7, a directional spray head 6 and a dust hood 8 to the traditional belt sander, without modifying the core components such as the power system 1, sanding belt 2, and grinding table 4. This can simultaneously solve the two major problems of high-temperature oxidation of copper parts and grinding dust, which reduces the cost of equipment modification and can adapt to the upgrade needs of existing sanders, making it highly practical.

[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
