Description

Technical Field

[0001] This application relates to the field of metal processing technology, and in particular to a processing apparatus for enhancing the corrosion resistance of brass alloys. Background Technology

[0002] Brass alloys are widely used in electronics, construction, and shipbuilding due to their excellent mechanical and machinability. However, traditional brass alloys have poor corrosion resistance in corrosive environments, limiting their application in certain demanding scenarios. To improve the corrosion resistance of brass alloys, precious metals (such as silver and gold) are usually added, but this significantly increases material costs.

[0003] In recent years, researchers have been working to balance corrosion resistance and cost by optimizing alloy composition and processing technology, but existing technologies still suffer from problems such as high precious metal content or insufficient corrosion resistance.

[0004] The main drawback of existing technologies is that they cannot effectively reduce the amount of precious metals used while ensuring corrosion resistance, resulting in high material costs. To address this issue, a processing device for enhancing the corrosion resistance of brass alloys is proposed. Utility Model Content

[0005] The purpose of this application is to provide a processing apparatus that enhances the corrosion resistance of brass alloys. While ensuring that the corrosion resistance of brass alloys is close to that of pure gold, it significantly reduces the amount of precious metals (such as silver) used, thereby reducing material costs and solving the problems mentioned in the background art.

[0006] The processing apparatus for enhancing the corrosion resistance of brass alloys provided in this application adopts the following technical solution: A processing apparatus for enhancing the corrosion resistance of brass alloys includes a base, a melting unit, a silver storage unit, a transition unit, a forming unit, and a cooling unit. The melting unit includes a melting tank fixedly connected to the upper surface of the base by a reinforcing bracket. An electromagnetic heating coil is installed inside the melting tank. A copper conveying pipeline is connected to the bottom end of the melting tank. A first solenoid valve is installed on a section of the copper conveying pipeline. The silver storage unit includes a heat preservation tank fixedly connected to the upper surface of the base by a reinforcing bracket. A heating rod is installed inside the heat preservation tank. A first silver conveying pipeline is connected to the bottom end of the heat preservation tank. A temporary storage cylinder is connected to the bottom end of the first silver conveying pipeline. A second silver conveying pipeline is connected to the bottom end of the temporary storage cylinder. A second solenoid valve is installed on a section of both the first and second silver conveying pipelines. The transition unit includes a weighing device mounted on the upper surface of the base. A transition molten pool is fixedly connected to the upper surface of the weighing device. The bottom ends of the copper supply pipeline and the second silver supply pipeline are both connected to the interior of the transition molten pool. A transfer unit is installed on one side of the bottom of the transition molten pool, and the other end of the transfer unit is connected to the inlet of the forming unit.

[0007] By adopting the above technical solution, and through the cooperation between the smelting unit, the silver storage unit, and the transition unit, the corrosion resistance of brass alloys can be made close to that of pure gold, provided that the mass fraction of silver does not exceed 35%. This significantly reduces the amount of precious metals used, achieves a balance between corrosion resistance and cost, and broadens the application range of brass alloys.

[0008] Preferably, a first servo motor is fixedly connected to the upper surface of the melting tank, and a first spiral blade is fixedly connected to the output end of the first servo motor.

[0009] By adopting the above technical solution, the first servo motor drives the first spiral blade to stir the melt, thereby improving the temperature uniformity of the copper substrate to a certain extent and reducing component segregation from the source.

[0010] Preferably, the top of the smelting vessel is connected to a copper material replenishment pipe, and the inner wall of the smelting vessel is inlaid with a first measuring range bar.

[0011] By adopting the above technical solution, the first range bar monitors the liquid level in the smelting tank in real time. When the level is lower than the threshold, the copper material is replenished through the copper material replenishment pipe to achieve dynamic balance between smelting and replenishment.

[0012] Preferably, the inner wall of the temporary storage cylinder is inlaid with a second measuring range bar, the inner wall of the heat preservation tank is inlaid with a third measuring range bar, and the top of the heat preservation tank is equipped with a silver material replenishment pipe.

[0013] By adopting the above technical solution, the second and third measuring bars monitor the liquid levels of the temporary storage cylinder and the insulation tank respectively, while the silver replenishment pipe can replenish the silver material to the insulation tank in a timely manner.

[0014] Preferably, a second servo motor is fixedly connected to the top of the transition molten pool, and a second helical blade is fixedly connected to the output end of the second servo motor.

[0015] By adopting the above technical solution, when the second servo motor is started, it can drive the second spiral blade to perform turbulent enhanced mixing, so that the silver is more evenly distributed in the copper melt, thereby optimizing the processing technology and improving the production quality.

[0016] Preferably, the molding unit is fixedly connected to the upper surface of the base, and the cooling unit includes a coolant tank installed on one side of the molding unit, with an injection pipe installed on the top of the coolant tank and a drain pipe installed on the bottom of the coolant tank.

[0017] By adopting the above technical solution, the coolant tank can be conveniently replaced with condensate through the injection pipe and the drain pipe, making it easy to use.

[0018] Preferably, two circulation pumps are installed on one side of the coolant tank, and a condenser tube is installed at the bottom of the molding unit, with both ends of the condenser tube installed at the ports of the two circulation pumps respectively.

[0019] By adopting the above technical solution, when the two circulating pumps are started, the condensate in the coolant tank can be circulated and transported through the condenser pipe, thereby achieving the effect of cooling the molding unit.

[0020] Preferably, a cooling fan is installed at the bottom of the other side of the molding unit, and the cooling fan is adapted to the condenser pipe.

[0021] By adopting the above technical solution, when the cooling fan is started, the air circulation around the molding unit can be accelerated, thereby optimizing the cooling effect of the cooling unit.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This processing device for enhancing the corrosion resistance of brass alloys, through the coordinated operation of a smelting unit, a silver storage unit, and a transition unit, can achieve corrosion resistance of brass alloys approaching that of pure gold, while maintaining a silver mass fraction of no more than 35%. This significantly reduces the amount of precious metals used, achieving a balance between corrosion resistance and cost, and broadening the application range of brass alloys. Brass is smelted in the smelting unit and fed into the transition molten pool via a copper conveying pipeline and a first solenoid valve. At this point, a weighing device measures the mass of the copper material, and the required mass of molten silver is calculated based on this mass. The molten silver is stored inside an insulated tank. The liquid silver is heated and kept warm by a heating rod. Then, the first silver supply line is activated to transport the liquid silver into the temporary storage tank. The liquid volume is observed through the second measuring bar to achieve a quantitative transfer effect. Then, the second solenoid valve is activated to transport the liquid silver inside the temporary storage tank to the transition molten pool to mix with the copper material. At this time, the weighing device can weigh the total mass of the copper material and the liquid silver to more accurately calculate the mass of the added liquid silver. The reason for this setting is that errors are inevitable during the processing. By using the temporary storage tank, the second solenoid valve and the weighing device in combination, the quality of the liquid silver can be controlled in two ways, reducing errors.

[0028] Example 2: A processing device for enhancing the corrosion resistance of brass alloys. Based on the same concept as Example 1 above, this example proposes a transition unit 4 including a weighing device 401 mounted on the upper surface of the base 1.

When the two circulation pumps 704 are started, the coolant in the coolant tank 701 can be circulated and transported through the condenser pipe 705, thereby achieving the effect of cooling the molding unit 6. A cooling fan 706 is installed at the bottom of the other side of the molding unit 6. The cooling fan 706 is adapted to the condenser pipe 705.

[0030] The implementation principle of this application embodiment is as follows: A brass substrate is heated and melted in a melting tank 201 by an electromagnetic heating coil 202. A first servo motor 203 drives a first spiral blade 204 to stir the mixture, ensuring uniform temperature. The liquid level is monitored in real time via a first range bar 208. When the level falls below a threshold, copper is added through a copper replenishment pipe 207. The molten copper is quantitatively fed into the transition molten pool 402 via a copper delivery pipe 205 and a first solenoid valve 206. At this time, a weighing device 401 accurately weighs the copper and calculates the required amount of silver. Then, a heat preservation tank 301 maintains a constant temperature for the silver liquid via a heating rod 302. The silver liquid flows into a temporary storage cylinder 304 via a first silver delivery pipe 303 and a second solenoid valve 306. After preliminary verification of the liquid volume by the temporary storage cylinder 304 and the second range bar 307, the silver liquid is injected into the transition molten pool 402 via a second silver delivery pipe 305 and a second solenoid valve 306. This dual weighing closed-loop system reduces the error in silver addition, allowing for more precise control of the silver content. After the mixed melt is stirred by the second helical blades 404 driven by the second servo motor 403, it is transferred by the transfer unit 5 to the forming unit 6 for casting. The casting is cooled in the cooling unit 7. During cooling, two circulating pumps 704 can be started to circulate the condensate through the condenser pipe 705 for cooling. With the help of the activated cooling fan 706, the cooling effect can be accelerated, which facilitates the demolding process.
