Description

Technical Field

[0001] This utility model relates to the field of beryllium copper strip processing technology, specifically to an electrolytic polishing device for corrosion-resistant beryllium copper strip. Background Technology

[0002] Corrosion-resistant beryllium copper strip is a copper alloy strip with beryllium as the main alloying element. It has excellent corrosion resistance and mechanical properties and is widely used in high-temperature, high-conductivity, and high-wear-resistant fields. During the processing of corrosion-resistant beryllium copper strip, the surface of beryllium copper strip can achieve a high degree of smoothness through electrolytic polishing, and even achieve a mirror reflection effect, which significantly improves its decorative and aesthetic properties.

[0003] When electropolishing corrosion-resistant beryllium copper strips, the strips are fed into an electrolytic cell for ion exchange to achieve the desired polishing effect. However, in existing technologies, some dust stubbornly adheres to the strips before they are fed into the cell. The friction between the strips and the electrolyte during the process is insufficient to remove this dust, affecting the electropolishing effect. Furthermore, after electropolishing, the strips retain electrolyte. Current techniques use wiping cloths to absorb and remove this electrolyte, but prolonged use leads to an increase in electrolyte concentration, resulting in poor cleaning of the strips.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4As shown in this embodiment, the corrosion-resistant beryllium copper strip electrolytic polishing device includes an electrolytic cell 1. Components for feeding and winding the beryllium copper strip are provided at both ends of the electrolytic cell 1. A top plate 2 is fixedly installed on the top of the electrolytic cell 1 by bolts. Mounting seats 3 are symmetrically fixed on both sides of one end of the top plate 2. A rotating roller 4 is symmetrically mounted between the two mounting seats 3 via bearings. The rotation direction of the rotating roller 4 is opposite to the conveying direction of the beryllium copper strip. A cleaning cloth 5 is fixed to the outer ring of the rotating roller 4. The beryllium copper strip is positioned between the two rotating rollers 4. Air pipes 6 are symmetrically fixedly installed inside the electrolytic cell 1, and the air pipes 6 are connected to the outlet of an air blowing system. The beryllium copper strip is positioned between the two air pipes 6. Air holes 7 are equidistantly opened in the middle of the air pipes 6. The angle between the outlet direction of the air holes 7 and the beryllium copper strip is 30 degrees. An electrolytic polishing component is installed between the middle of the top plate 2 and the electrolytic cell 1, allowing the beryllium copper strip to pass through the two rotating rollers 4. In between, the beryllium copper strip is fed through the feeding assembly and simultaneously wound by the winding assembly, achieving continuous conveying of the beryllium copper strip. Before conveying the beryllium copper strip to the electrolytic cell 1, two rotating rollers 4 are driven to rotate synchronously. The rotation of the rollers 4 causes relative movement with the conveyed beryllium copper strip. The cleaning cloth 5 on the rollers 4 cleans the stubborn dust adsorbed on the beryllium copper strip, preventing excessive dust adsorption on the beryllium copper strip and hindering subsequent electrolytic polishing of the beryllium copper strip. When the beryllium copper strip is at When the beryllium copper strip is in the electrolyte in the electrolytic cell 1, the corrosion-resistant beryllium copper strip is electropolished by the operation of the electropolishing assembly. Then, the electropolished beryllium copper strip area will pass through the position between the two air pipes 6. High-pressure air is blown into the air pipes 6 by the air blowing system. The high-pressure gas will be discharged from the air hole 7. The high-pressure gas will blow the electrolyte on the surface of the beryllium copper strip and drive the electrolyte on the surface of the beryllium copper strip to flow into the electrolytic cell 1 along the surface of the beryllium copper strip, thereby cleaning the electrolyte on the surface of the beryllium copper strip.

[0022] like Figures 1 to 4 As shown, the electrolytic polishing assembly includes a power system 8, a hanger 9, a cathode column 10, and an anode roller 11. The power system 8 is fixedly installed at one end of the electrolytic cell 1. The power system 8 includes components such as a transformer and a rectifier. The specific structure, model, and connection of these components are conventional and will not be described in detail in this utility model. The hanger 9 is symmetrically installed in the middle of the top plate 2. A hanging rod is provided in the middle of the top plate 2 for suspending the hanger 9. The cathode column 10 is fixedly installed at the bottom of the hanger 9 and extends into the electrolyte of the electrolytic cell 1. The cathode of the power system 8 is electrically connected to the cathode column 10 through a wire. The two cathode columns 10 are connected in series through a wire. The anode roller 11 is movably installed at the lower middle position of the electrolytic cell 1. The anode of the power system 8 is electrically connected to the anode roller 11 through a wire. The anode roller 11 also extends into the electrolyte of the electrolytic cell 1.

[0023] When the beryllium copper strip is immersed in the electrolyte in the electrolytic cell 1, the beryllium copper strip in contact with the anode roller 11 acts as the anode, and the cathode column 10 acts as the cathode. After a DC voltage is applied through the power supply system 8, the current density is higher at the microscopic protrusions on the surface of the beryllium copper strip, resulting in faster anodic dissolution, while the dissolution is slower at the depressions. This achieves surface leveling of the beryllium copper strip and realizes electrolytic polishing of the corrosion-resistant beryllium copper strip.

[0024] like Figures 1 to 4 As shown, the top plate 2 has symmetrical sliding holes 12 in the middle. A sliding rod 13 is slidably installed inside the sliding hole 12. A mounting bracket 14 is fixedly installed between the bottom ends of the two sliding rods 13. The anode roller 11 is rotatably installed in the middle of the mounting bracket 14 through a bearing. A spring 20 is sleeved on the outer side of the top end of the sliding rod 13. One end of the spring 20 is fixedly connected to the top end of the sliding rod 13, and the other end of the spring 20 is fixedly connected to the upper surface of the top plate 2.

[0025] During the conveying process of the beryllium copper strip, the beryllium copper strip is always in contact with and squeezed by the anode roller 11. The continuous pulling of the top of the slide bar 13 by the spring 20 will drive the anode roller 11 to continuously squeeze the beryllium copper strip, so as to keep the beryllium copper strip taut during conveying.

[0026] like Figures 1 to 4 As shown, guide rollers 15 are installed at both ends of the top plate 2. Each guide roller 15 includes two conveying rollers, which are arranged one above the other. The beryllium copper strip is located between the two conveying rollers between the two guide rollers 15.

[0027] The beryllium copper strip can be guided and positioned by the guide rollers 15.

[0028] like Figures 1 to 4 As shown, a first motor 16 is fixedly installed on one side of one of the mounting bases 3. The output end of the first motor 16 is fixedly connected to the end of the rotating roller 4 through a shaft connector. A gear 17 is fixedly installed on the end of the rotating roller 4, and the two gears 17 between the two rotating rollers 4 are meshed together.

[0029] The first motor 16 is energized and drives one of the rollers 4 to rotate. The two rollers 4 are driven to rotate synchronously by the meshing of the two gears 17 on the two rollers 4.

[0030] like Figures 1 to 4 As shown, a second motor 18 is fixedly installed on the upper surface of the middle part of the top plate 2. The output shaft of the second motor 18 passes through the top plate 2 and is fixedly installed on a stirring shaft 19. The output shaft of the second motor 18 is rotatably connected to the top plate 2.

[0031] The second motor 18 drives the stirring shaft 19 to rotate, which can agitate the electrolyte in the electrolytic cell 1 to control the uniformity of the electrolyte.

[0032] This utility model provides an electrolytic polishing device for corrosion-resistant beryllium copper strips, the specific working principle of which is as follows:

[0033] In operation, the beryllium copper strip is sequentially passed between two rotating rollers 4, between the two conveying rollers of a guide roller 15, below the anode roller 11, and between the two conveying rollers of another guide roller 15. The beryllium copper strip is fed out by the feeding assembly and simultaneously wound up by the winding assembly, achieving continuous conveying of the beryllium copper strip. Before the beryllium copper strip is conveyed to the electrolytic cell 1, the first motor 16, when energized, drives one of the rotating rollers 4 to rotate. The meshing of two gears 17 on the two rotating rollers 4 causes both rollers 4 to rotate synchronously. The rotation of the rollers 4 creates relative movement with the conveyed beryllium copper strip. The cleaning cloth 5 on the rollers 4 removes stubborn dust adsorbed on the beryllium copper strip, preventing excessive dust adsorption and subsequent hardening of the beryllium copper strip. In the electrolytic polishing of copper strip, when the beryllium copper strip is in the electrolyte in the electrolytic cell 1, the beryllium copper strip in contact with the anode roller 11 is the anode, and the cathode column 10 is the cathode. After the DC voltage is applied by the power supply system 8, the current density is higher at the microscopic protrusions on the surface of the beryllium copper strip, resulting in faster anodic dissolution, while the dissolution is slower at the depressions. This achieves the surface leveling of the beryllium copper strip and realizes the electrolytic polishing of the corrosion-resistant beryllium copper strip. Subsequently, the electrolytically polished beryllium copper strip area will pass through the position between the two air pipes 6. High-pressure air is blown into the air pipes 6 through the air blowing system. The high-pressure gas will be discharged from the air hole 7. The high-pressure gas will blow the electrolyte on the surface of the beryllium copper strip, which will drive the electrolyte on the surface of the beryllium copper strip to flow into the electrolytic cell 1 along the surface of the beryllium copper strip, thus cleaning the electrolyte on the surface of the beryllium copper strip.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
