Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy manufacturing technology, and in particular to a manufacturing device for a novel aluminum alloy for dicing blade aluminum discs. Background Technology

[0002] Aluminum alloys, as a typical representative of lightweight metal materials, have become core structural materials in fields such as semiconductors, aerospace, and precision machinery due to their low density, high specific strength, excellent thermal and electrical conductivity, strong corrosion resistance, and wide adaptability to manufacturing processes. Taking the semiconductor industry as an example, 5083 aluminum-magnesium alloy, with a manganese content of 0.4%-1%, possesses high corrosion resistance, a fine surface quality, and excellent strength and toughness, making it widely used in the manufacture of substrates for high-speed rotating components, such as dicing blades and precision tools like flying discs. These products have extremely stringent requirements for surface roughness.

[0003] A novel aluminum alloy manufacturing device with injection molding function, disclosed in announcement number CN214236235U, includes a feed inlet, a main body, and a housing. A resistance heating plate is movably connected to the other end of the housing. A connecting block is movably connected to the top of the housing, and a motor is movably connected to the top of the connecting block. A rotating rod is movably connected to the bottom of the motor, and a stirring rod is movably connected to the other end of the rotating rod. A base is movably connected to the bottom of the housing, and a conveying pipe is movably connected to the bottom of the main body. Through a designed handle, a first movable rod, a gear, a first connecting rod, a rack, and a baffle, the baffle moves inside the conveying pipe. A designed first bolt, a first spring, and a fixing block fix the position of the baffle inside the conveying pipe, thus solving the problem of difficulty in adjusting the device's discharge speed, which would reduce the device's working efficiency.

[0004] The aforementioned prior art uses a single stirring rod to agitate and mix the raw materials for aluminum alloy manufacturing. The mixing effect of the raw materials is poor, resulting in local compositional differences in the ingots or castings. Furthermore, the prior art lacks a filtration design for the melt, and residual oxide inclusions and micron-sized inclusions in the melt will significantly reduce the mechanical properties and appearance quality of the castings. The presence of inclusions will also cause local component segregation in the castings, affecting the uniformity of the microstructure and thus reducing the manufacturing quality of the aluminum alloy. Therefore, corresponding improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a new aluminum alloy manufacturing apparatus for dicing blade aluminum discs, in order to solve the problems mentioned in the background art, such as poor mixing effect of aluminum alloy manufacturing raw materials and lack of impurity filtration, which affect the quality of aluminum alloy manufacturing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a manufacturing device for a new type of aluminum alloy for dicing blade aluminum discs, comprising a heat-insulating furnace, a fixed plate, and a control panel, wherein the fixed plate is fixed to the bottom of the heat-insulating furnace, and the control panel is connected to the outside of the heat-insulating furnace;

[0007] The insulated furnace is detachably connected to a top cover, and an air injection pipe is connected to one side of the top of the top cover. When not in use, the air injection pipe is filled with a sealing plug. The insulated furnace is equipped with a stirring mechanism and a heating chamber. The heating chamber is wound with heating wire. The bottom of the insulated furnace is threadedly connected to a discharge pipe, and a material valve is installed on the discharge pipe. The discharge pipe is filled with a filter assembly.

[0008] Furthermore, both sides of the heat-insulating furnace are connected to fixing blocks, and each fixing block is provided with a mounting hole. A fixing column passes through each mounting hole, and the fixing column is fixed to both sides of the bottom end of the top cover. A fixing sleeve is threaded to the outside of each fixing column.

[0009] Furthermore, the stirring mechanism includes a drive motor, which is fixed to the top of the top cover. The output end of the drive motor is connected to a rotating shaft via a connecting coupling, and one end of the rotating shaft extends into the interior of the heat-preserving furnace. Stirring rods are fixed on both sides of the rotating shaft, and connecting plates are fixed on both sides of the stirring rods. A support spring is connected to one side of each connecting plate.

[0010] Furthermore, each of the supporting springs is connected to a sliding plate at one end, and a sliding column runs through the interior of each sliding plate.

[0011] Furthermore, each of the stirring rods is provided with a rectangular cross-section groove, and one end of each sliding rod extends into the groove and is slidably connected to the groove.

[0012] Furthermore, the filter assembly includes a foam ceramic filter plate slidably connected inside the discharge pipe, and a support ring is connected inside the discharge pipe below the foam ceramic filter plate. A return spring is evenly connected between the support ring and the foam ceramic filter plate.

[0013] Furthermore, four reset springs are provided between the foam ceramic filter plate and the support ring, and are arranged in a ring shape.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the new aluminum alloy manufacturing device for the dicing blade aluminum disc not only has the effect of stirring and mixing raw materials, but also has the effect of filtration of melt;

[0015] Aluminum alloy manufacturing raw materials are injected into a heat-insulating furnace. Heating wires are used to heat the furnace, and a drive motor is used to rotate the rotating shaft, stirring rod, and connecting plate to stir and mix the raw materials. Intensive convection breaks the temperature and concentration gradients inside the heat-insulating furnace, so that the alloy elements are evenly distributed, the heating is uniform, and the melt quality is optimized.

[0016] During the rotation of the rotating shaft, centrifugal force is generated, which throws the sliding plate outward and makes the sliding column slide in the sliding groove. The support spring provides elastic support, which can adjust the stirring range and ensure the comprehensiveness and efficiency of stirring. In the aluminum alloy manufacturing process, it can accelerate the dissolution and dispersion of additives, avoid local agglomeration, and improve the manufacturing quality of aluminum alloys.

[0017] Gas is introduced into the heat-preserving furnace through the gas injection pipe, forming bubbles that adsorb hydrogen and oxide inclusions. These bubbles rise and are discharged, which helps to improve the purity of the melt and ensure the casting quality of aluminum alloy dicing blades and flying discs.

[0018] The melt is discharged through a discharge pipe. During this process, a foam ceramic filter plate is used to filter out residual oxide inclusions and micron-sized slag in the melt, thereby improving the manufacturing quality of the aluminum alloy. The melt impacts the foam ceramic filter plate during its descent, and a return spring reduces the impact force, minimizing damage to the foam ceramic filter plate. The elastic return spring also prevents impurities from forming a filter cake on the surface of the foam ceramic filter plate, maintaining a stable filtration flow rate. Attached Figure Description

[0026] 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. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figures 1-5 The present invention provides the following technical solution:

[0028] Example 1

[0029] To address the issue of poor manufacturing quality of aluminum alloys in existing technologies, the following technical solution is disclosed. Please refer to the details below. Figure 1 , Figure 2 , Figure 3 , Figure 4 A manufacturing apparatus for a novel aluminum alloy for dicing blade aluminum discs includes a heat-insulating furnace 1, a fixed plate 2, and a control panel 3. The fixed plate 2 is fixed to the bottom of the heat-insulating furnace 1, and the control panel 3 is connected to the outside of the heat-insulating furnace 1. A top cover 4 is detachably connected to the top of the heat-insulating furnace 1, and an air injection pipe 8 is connected to one side of the top of the top cover 4. The air injection pipe 8 is filled with a sealing plug when not in use. An agitation mechanism 7 is provided inside the heat-insulating furnace 1. The agitation mechanism 7 includes a drive motor 701, and the drive motor 701 is fixed to the top of the top cover 4. The output end of the drive motor 701 is connected to a... A coupling connects to a rotating shaft 702, with one end of the rotating shaft 702 extending into the interior of the heat-insulating furnace 1. Stirring rods 703 are fixed on both sides of the rotating shaft 702, and connecting plates 704 are fixed on both sides of the stirring rods 703. A support spring 705 is connected to one side of each connecting plate 704. A sliding plate 706 is connected to one end of each support spring 705, and a sliding column 707 passes through the interior of each sliding plate 706. A rectangular groove 708 is provided on each stirring rod 703, and one end of each sliding column 707 extends into the groove 708 and is slidably connected to the groove 708.

[0030] In use, aluminum alloy casting raw materials are put into the heat-preserving furnace 1, then the top cover 4 is placed on the heat-preserving furnace 1, and the stirring mechanism 7 is placed into the heat-preserving furnace 1 accordingly. Then, the drive motor 701 is driven to rotate the rotating shaft 702, which in turn drives the stirring rod 703 and the connecting plate 704 to rotate synchronously. This stirs and mixes the raw materials in the heat-preserving furnace 1, ensuring that the aluminum alloy raw materials are heated evenly and improving the melting efficiency. In addition, during this process, the rotation of the rotating shaft 702 generates centrifugal force, which throws the sliding plate 706 outward to optimize the stirring effect and makes the sliding column 707 slide in the sliding groove 708, which limits and guides the movement of the sliding plate 706, improving the manufacturing quality of aluminum alloy.

[0031] The heat-insulating furnace 1 is connected to two fixed blocks 5 on both sides, and each fixed block 5 is provided with an installation hole. A fixed post 6 passes through each installation hole, and the fixed post 6 is fixed to both sides of the bottom end of the top cover 4. A fixed sleeve 601 is threadedly connected to the outside of the fixed post 6.

[0032] In this embodiment, inert gases such as nitrogen and argon are injected into the heat-insulating furnace 1 through the gas injection pipe 8. Hydrogen in the aluminum alloy melt is removed through physical adsorption and chemical action. The fixing sleeve 601 is screwed off from the fixing column 6. Then, the top cover 4 is pulled to detach the fixing column 6 from the mounting hole on the fixing block 5, so that the top cover 4 can be separated from the heat-insulating furnace 1 for later inspection, cleaning and maintenance.

[0033] Example 2

[0034] This embodiment differs from Embodiment 1 in that it utilizes a filter assembly to filter the melt and effectively remove impurities. Therefore, the following technical solution is disclosed; please refer to the details. Figure 1 , Figure 2 , Figure 5 The heat-insulating furnace 1 has a heating chamber 101 inside, and a heating wire 9 is wound inside the heating chamber 101. The bottom end of the heat-insulating furnace 1 is threadedly connected to a discharge pipe 10, and a material valve 11 is provided on the discharge pipe 10. The discharge pipe 10 is filled with a filter assembly. The filter assembly includes a foam ceramic filter plate 12 slidably connected inside the discharge pipe 10, and a support ring 13 is connected inside the discharge pipe 10 below the foam ceramic filter plate 12. Return springs 14 are evenly connected between the support ring 13 and the foam ceramic filter plate 12. Four return springs 14 are provided between the foam ceramic filter plate 12 and the support ring 13 and are distributed in a ring shape.

[0035] In this embodiment, the heating wire 9 in the heating chamber 101 is used to heat-melt the aluminum alloy manufacturing material inside the heat-insulating furnace 1 to form a melt. The melt is discharged through the discharge pipe 10 for later casting to obtain a new type of aluminum alloy for dicing blade aluminum discs. During this process, the melt is filtered through the foam ceramic filter plate 12 to remove temporary oxide inclusions in the melt, improve the purity, reduce defects, and use the return spring 14 to reduce the impact force of the melt and generate elastic force to make the foam ceramic filter plate 12 vibrate, avoid the formation of filter cake and prevent blockage. Later, the discharge pipe 10 can be unscrewed from the heat-insulating furnace 1 for later cleaning and maintenance.
