Description

TECHNICAL FIELD

[0001] The present application relates to the field of additive processing equipment, in particular to an iron additive processing equipment and method for aluminum alloy processing. BACKGROUND

[0002] In aluminum alloy processing, iron plays a complex and critical role, both as the most common impurity and as an intentionally added element in certain alloys. Referring to it as "iron additive" generally means purposefully adding iron elements to the melt to achieve specific performance goals. The main effects of iron additives include:

[0003] ① Improve wear resistance: Iron forms hard intermetallic phases (Al3Fe, Al6Fe, Al3FeSi, etc.), which are dispersedly distributed in the aluminum matrix, which can effectively resist wear. Typical applications: piston alloys (such as A390 - containing about 1.3% iron), cylinder liners, wear-resistant lining plates, sliding bearing alloys, etc. ② Improve high temperature performance: Iron-containing phases (especially those with higher thermal stability) are less likely to dissolve or coarsen at high temperatures, which helps to maintain the strength and creep resistance of the alloy at high temperatures. Typical applications: engine pistons (such as A390, 4032 containing about 0.9-1.0% iron), turbocharger housings, high-temperature structural parts. ③ Improve cutting performance: Hard iron-containing phases help to break the chips (chip breaking effect) during machining, reduce tool wear, and improve workpiece surface finish. Iron is one of the important elements in free-cutting aluminum alloys. Typical applications: free-cutting alloys (such as some specific 2000 series wrought alloys or 8000 series alloys). ④ Grain refinement / phase morphology change: During casting, iron can act as a heterogeneous nucleation core, helping to refine α-Al grains. By adding other elements (such as Mn, Cr, Co), the iron phase can be transformed from harmful needle-like to relatively harmless Chinese character-like, block-like or spherical. ⑤ Reduce costs: High-iron-content aluminum alloys (such as some cast alloys) sometimes tolerate higher proportions of inexpensive scrap aluminum (which usually contains higher iron). ⑥ Specific alloy system: 8000 series aluminum alloys: This series mainly includes aluminum-iron alloys, usually also containing other elements (such as Ce, Si). Designed for high-temperature applications (such as wire, heat exchanger fins) and special purposes (such as Al-Fe-V-Si alloys for aerospace). Hypereutectic Al-Si cast alloys: such as A390 (Al-17Si-4.5Cu-0.6Mg-1.3Fe), high iron content is mainly used to improve wear resistance (in combination with primary silicon).

[0004] The main component in the iron additive is iron powder, in addition to a small amount of combustion aids or other materials such as aluminum powder, etc. are needed to be added according to different purposes, therefore, in the process of producing and processing the iron additive, the iron powder and other materials need to be mixed through a material mixing device.

[0005] For example, patent application number 202310523671.5 discloses a material mixing device, which includes: a bracket, an outer cylinder, an inner cylinder and a conveying pipe. The bracket is provided with a conveying mechanism, the outer cylinder is mounted on the bracket, the outer cylinder is open at the top, and the bottom is a conical structure, a discharge valve is installed at the bottom, the inner cylinder is mounted inside the outer cylinder, a first chamber is limited between the inner cylinder and the outer cylinder, a feed port is provided above the first chamber for the conveying mechanism to feed the material into the first chamber, a discharge port is provided below the first chamber, the discharge port is connected to the bottom of the outer cylinder, and the discharge port has two states, open and closed, the conveying pipe is mounted in the inner cylinder, a second chamber is limited between the inner cylinder and the conveying pipe, and an auger is also provided in the conveying pipe. The beneficial effects of the present invention are: the material can be fully mixed, and the device has a high loading rate and low energy consumption.

[0006] Patent application number 202311214584.8 discloses a material mixing device, which includes a mixing box, a stirring device and an air supply device. A stirring chamber is formed inside the mixing box; the stirring device includes a stirring shaft, and the stirring shaft includes a rotating shaft stirring blade. The rotating shaft can move along its own axial direction, and a fluid channel is provided on the stirring shaft; the air supply device is connected to the fluid channel. In the material mixing device provided by the present invention, the stirring blade can be driven to move by the rotating shaft to increase the stirring range of the stirring blade, thereby being able to more efficiently mix the raw materials in the stirring chamber and improve the mixing effect. During the stirring process, compressed gas can act on the inner wall of the mixing box through the stirring blade, avoiding the phenomenon of large-scale adhesion of powder raw materials to the wall. Before the next mixing, there is no need to spend a lot of time and manpower to clean the mixing box, which reduces labor costs and increases work efficiency.

[0007] Patent application number 202411952736.9 discloses a material mixing device, including a cylinder, a feeding device, a scraping device, a spraying device and a stirring device. A mixing chamber is formed in the cylinder, and a mixing zone and a stirring zone that are connected to each other are provided in the mixing chamber; the feeding device is connected to the mixing zone and is suitable for feeding solid materials into the mixing zone; the scraping device is rotatably arranged in the mixing zone, and at least part of the scraping device is in contact with the inner wall of the mixing zone; at least part of the spraying device extends to the mixing zone and is suitable for feeding liquid materials into the mixing zone, and the spraying device is constructed as a plurality of devices arranged on both sides of the scraping device, each of which is provided with at least one spraying outlet, and the spraying outlet is inclined toward the bottom of the mixing zone; the stirring device is rotatably arranged in the stirring zone to stir the mixture in the stirring zone. According to the material mixing device of the present invention, the material mixing effect is improved by rationally arranging the scraping device, the stirring device and the spraying device.

[0008] When using the above-mentioned material mixing device and similar devices, it is often necessary to first mix the various material components in proportion and then add them into the mixing device. For the processing of iron additives, it is relatively cumbersome due to the need to frequently switch other materials such as combustion aids and aluminum powder, and frequently weigh and calculate the ratio before adding the materials, which requires improvement.

[0036] The material distribution mechanism includes a material distribution box 9, the bottom of the material distribution box 9 is fixedly connected to the upper end of the support column 8, the top of the material distribution box 9 is fixedly connected to the lower end of the first bracket 3, the first bracket 3 connects the material storage barrel 2 with the material distribution box 9, and a drive motor 10 is provided on the rear side of the material distribution box 9. The drive motor 10 is fixedly connected to the material distribution box 9 through the second bracket. The power output end of the drive motor 10 is fixedly connected to one end of the first rotating shaft 11, and the other end of the first rotating shaft 11 passes through the material distribution box 9 and extends into the material distribution box 9. The first rotating shaft 11 is connected to the material distribution assembly.

[0037] The material distribution assembly includes a turntable 13, which is connected to the first rotating shaft 11 through a connecting assembly. A driving block 15 is installed on the edge of the turntable 13. One side of the driving block 15 is fixed to the turntable 13, and the other side of the driving block 15 is arc-shaped and provided with a plurality of first tooth grooves 14; a cavity 22 is opened inside the left side of the material distribution box 9, and a lever 20 is set in the cavity 22. The lever 20 is sleeved on the second rotating shaft 21, and the lever 20 rotates with the second rotating shaft 21. The end of the second rotating shaft 21 is fixed to the material distribution box 9, and a first discharge port 16 is opened on the material distribution box 9. The first discharge port 1 6 is located on the right side of the lever 20, the first discharge port 16 connects the cavity 22 with the interior of the material distribution box 9, the lever 20 is located in the first discharge port 16, and a plurality of second tooth grooves 18 are provided on the surface of the lever 20. The connecting component includes a limit block 23, a plurality of limit blocks 23 are fixedly provided on the outside of the first rotating shaft 11, and a plurality of card slots 12 are provided in the center of the turntable 13. The card slots 12 are located on the outside of the first rotating shaft 11, and the limit blocks 23 are slidably inserted into the card slots 12; a base 17 is fixedly provided on the inner wall of the cavity 22, and the base 17 is fixedly connected to the upper end of the elastic baffle 19, and the elastic baffle 19 is located on the upper right side of the lever 20.

[0038] A cover plate 4 is provided on the front side of the material distribution box 9, and the edge of the cover plate 4 is connected to the edge of the material distribution box 9 by a plurality of connecting screws 5. A second discharge port 6 is provided at the bottom left side of the material distribution box 9.

[0039] Place iron powder in the material storage barrel 2 on the right, and place the combustion aid in the material storage barrel 2 on the left.

By opening the cover 4 and replacing the turntable 13 with different numbers of driving blocks 15, the ratio of iron powder to combustion aid can be quickly changed.
