Abstract
Description
Technical Field
[0001] This utility model relates to the field of micro-arc oxidation technology, and in particular to a micro-arc oxidation device for magnesium alloy powder. Background Technology
[0002] Magnesium alloys, with their light weight and high specific strength and stiffness, are attracting widespread attention in the new energy vehicle sector and the low-altitude economy, represented by drones, as we develop new types of productive forces. Particularly in the field of special magnesium-based composite material molding, based on nano-oxide particle doping and represented by particle die casting and powder metallurgy, the doping process, whether through external reinforcement or in-situ growth, often results in the agglomeration of nano-oxide particles due to their size efficiency and aggregation effect. This leads to uneven distribution of the doped nano-oxide particles, failing to provide reinforcement and instead producing a series of side effects.
[0003] Existing electrochemical oxidation methods first prepare a layer of nano-sized magnesium oxide and aluminum oxide ceramics on the surface of magnesium alloy particles used to prepare magnesium-based oxide particle-doped composite materials. These nano-sized ceramic layers are bonded to the magnesium alloy powder particle matrix in a welding manner. During the melting process of the powder matrix, the aggregation of nano-oxides is restricted. At the same time, within a limited space, they can be well mixed with the microdroplets of magnesium alloy melt after the powder particles are melted, which effectively improves the doping effect of magnesium-based composite materials prepared by doping with magnesium oxide, aluminum oxide and other nanoparticles.
[0004] However, in the existing devices, the electrolyte circulation and exchange inside the microparticle powder pile is difficult, resulting in uneven electrolyte distribution during the oxidation process, which affects the oxidation effect. Utility Model Content
[0005] The purpose of this invention is to provide a micro-arc oxidation device for magnesium alloy powder, which aims to solve the problem that in existing devices, the electrolyte circulation and exchange inside the microparticle powder pile is difficult, resulting in uneven electrolyte distribution during the oxidation process, thus affecting the oxidation effect.
[0006] To achieve the above objectives, this utility model provides a micro-arc oxidation device for magnesium alloy powder, including an electrolyte tank, a basket, and a support assembly. The basket is located on one side of the electrolyte tank, and the support assembly is mounted on the basket.
[0007] It also includes oxidation components,
[0008] The oxidation assembly includes a cathode perforated plate, a filter screen, an anode ring, an overflow pipe network, a circulation pump, a circulation pipe, a shower head, and a fixing component. The cathode perforated plate is mounted on the suspended basket and located on one side of the basket. The filter screen is mounted on the cathode perforated plate and located on one side of the cathode perforated plate. The anode ring is mounted on the suspended basket via the fixing component and located on one side of the basket. The overflow pipe network is mounted on the suspended basket and located on the side of the basket closest to the filter screen. The circulation pump is mounted on the electrolyte tank and located on one side of the electrolyte tank. The circulation pipe is connected to the circulation pump and located on one side of the circulation pump. The shower head is connected to the circulation pipe and located on the side of the circulation pipe closest to the suspended basket. The fixing component is mounted on the suspended basket.

The lifting beam frame is installed on the load-bearing wall and is located on one side of the load-bearing wall.
[0013] This utility model discloses a micro-arc oxidation device for magnesium alloy powder. When processing magnesium alloy particles, cleaned magnesium alloy particles are loaded into a basket. After loading, the powder particles adhering to the outside of the basket are removed. The basket is then suspended by the support assembly and moved to a suitable position in the electrolyte tank.

Thus, through the circulation pump, the circulation pipe, the spray nozzle, and the overflow pipe network, the electrolyte can be exchanged and circulated, solving the problem of difficult electrolyte circulation and exchange within the particle powder pile, thereby ensuring the uniformity and stability of the electrolyte during the oxidation process.

This solution solves the problem of difficulty in electrolyte circulation and exchange within the microparticle powder pile during use in existing devices, leading to uneven electrolyte distribution during oxidation and affecting the oxidation effect. It is understood that the aforementioned solution can be used in situations where easy electrolyte circulation and exchange are required.
[0023] In this embodiment, the basket 102 is connected and supported on a plane by the support assembly, so that the basket 102 can be positioned directly above the electrolyte tank 101.
[0024] The cathode perforated plate 103 is disposed on the suspended basket 102 and located on one side of the suspended basket 102; the filter screen 104 is disposed on the cathode perforated plate 103 and located on one side of the cathode perforated plate 103; the anode ring 105 is disposed on the suspended basket 102 via the fixing member and located on one side of the suspended basket 102; the overflow pipe network is disposed on the suspended basket 102 and located on the side of the suspended basket 102 near the filter screen 104; the circulation pump 107 is disposed on the electrolyte tank 101 and located on one side of the electrolyte tank 101; the circulation pipe 108 is connected to the circulation pump 107 and located on one side of the circulation pump 107; and the shower head 109 is connected to the circulation pipe 108. The connection is made of stainless steel and has good conductivity and corrosion resistance. The cathode plate 103 is designed with holes, which not only help to distribute the current evenly, but also promote the flow and circulation of the electrolyte in the basket 102. The cathode plate 103 is connected to the negative terminal of the power supply and is responsible for conducting the current to the electrolyte in the basket 102. The filter screen 104 is made of 200-mesh plastic nylon and can filter out impurities in the electrolyte in the basket 102. Impurities and particulate matter are eliminated. The anode ring 105 is made of TC4 titanium alloy wire. It acts as the anode, contacting the magnesium alloy particles to transfer current, creating an electric field during micro-arc oxidation and promoting the oxidation of the magnesium alloy particles. The overflow pipe network is used to recover excess electrolyte in the hanging basket 102 and return it to the electrolyte tank 101, forming a circulation. The circulation pump 107 is installed in the electrolyte tank 101, and the circulation pipe 108 is connected to the circulation pump 107. The shower head 109 is connected to the circulation pipe 108. The circulation pump 107 can transport electrolyte from the electrolyte tank 101 to the shower head 109 through the circulation pipe 108, and then spray it onto the hanging basket 102. The fixing component is installed on the magnesium alloy particles inside the basket 102. This fixing component can seal and shield the basket 102. When processing of the magnesium alloy particles is required, cleaned magnesium alloy particles of 80 mesh or finer are loaded into the basket 102. After loading, any powder particles adhering to the outside of the basket 102 are removed. The basket 102 is then suspended by the support assembly and moved to a suitable position in the electrolyte tank 101. The micro-arc oxidation power supply and the circulation pump 107 are then connected. The circulation pump 107 starts working. After the electrolyte flows steadily out of the overflow network 106 and the holes in the basket 102, the power circuit is closed to begin oxidation. When the overflow from the basket 102 is minimal, the process transitions to a cleaning process.After oxidation is complete, the electrolyte is exchanged and circulated through the circulation pump 107, the circulation pipe 108, the shower head 109, and the overflow pipe network 106. This solves the problem of difficult electrolyte circulation and exchange within the particulate powder pile, thus ensuring the uniformity and stability of the electrolyte during the oxidation process.
[0025] Secondly, the top cover 114 is connected to the suspended basket 102 via the top cover locking bolt 115, and is also connected to the anode ring 105, located on the side of the top cover 114 near the anode ring 105; the top cover locking bolt 115 is disposed on the top cover 114 and connected to the suspended basket 102; the pressure plate 116 is disposed on the suspended basket 102 and located on one side of the suspended basket 102; the pressure bolt 117 is disposed on the top cover 114 and located on the side of the top cover 114 near the pressure plate 116, and the top cover 114 is connected to the suspended basket 102 via the top cover locking bolt 115. 02 is connected by the top cover locking bolt 115. The top cover 114 can cover and seal the basket 102, thereby ensuring that the magnesium alloy particles in the basket 102 remain stable during the oxidation process and preventing electrolyte leakage. The pressure plate 116 is set in the basket 102, and the pressure bolt 117 is on the top cover 114. By turning the pressure bolt 117, the pressure plate 116 can be abutted and pushed to move in the basket 102, thereby causing the pressure plate 116 to press down and further fix the magnesium alloy particles in the basket 102.
[0026] Meanwhile, the positive electrode wire 110 is connected to the anode ring 105 and is located on one side of the anode ring 105; the negative electrode wire 111 is connected to the cathode orifice plate 103 and is located on one side of the cathode orifice plate 103; the power supply body 112 is connected to the positive electrode wire 110 and the negative electrode wire 111 respectively. The positive electrode wire 110 is connected to the anode ring 105, and the negative electrode wire 111 is connected to the cathode orifice plate 103. The power supply body 112 is connected to the positive electrode wire 110 and the negative electrode wire 111 respectively. Through the power supply body 112, the positive electrode wire 110, and the negative electrode wire 111, the required electrical energy can be provided to the cathode orifice plate 103 and the anode ring 105 during the oxidation process.
[0027] In addition, the filter screen 113 is fixedly connected to the electrolyte tank 101 and is located on the side of the electrolyte tank 101 near the circulation pump 107. The filter screen 113 is welded into the electrolyte tank 101, and the filter screen 113 can filter the impurities and particulate matter in the electrolyte in the electrolyte tank 101.
[0028] Finally, the load-bearing wall 118 is fixedly connected to the suspended basket 102 and is located on one side of the suspended basket 102; the lifting beam 119 is set on the load-bearing wall 118 and is located on one side of the load-bearing wall 118. The load-bearing wall 118 is connected and fixed to the suspended basket 102. The lifting beam 119 and the load-bearing wall 118 can serve as a support structure to suspend the suspended basket 102 above the electrolyte tank 101.
[0029] When using the magnesium alloy powder micro-arc oxidation device of this embodiment, when processing magnesium alloy particles is required, the cleaned magnesium alloy particles are loaded into the basket 102. After loading, the powder particles adhering to the outside of the basket 102 are removed. The basket 102 is then suspended by the support assembly and moved to a suitable position in the electrolyte tank 101. The micro-arc oxidation power supply and the circulation pump 107 are then connected, and the circulation pump 107 starts working. After the electrolyte flows steadily out of the overflow pipe network 106 and the hole of the basket 102, the power circuit is closed to start oxidation. When the overflow of the basket 102 is minimal, the washing process is initiated, and the oxidation ends. Thus, through the circulation pump 107, the circulation pipe 108, the shower head 109, and the overflow pipe network 106, the electrolyte can be exchanged and circulated, solving the problem of difficult electrolyte circulation and exchange inside the particle powder pile, thereby ensuring the uniformity and stability of the electrolyte during the oxidation process.
