Description

A method for developing impact-resistant and corrosion-resistant aluminum alloy materials Technical Field

[0001] This invention relates to the field of aluminum alloy development, specifically to a method for developing impact-resistant and corrosion-resistant aluminum alloy materials. Background Technology

[0002] Aluminum alloys are alloys with aluminum as the base and a certain amount of other alloying elements added. They are one of the light metal materials. Aluminum alloys have high strength, good casting performance, plastic processing performance, good electrical and thermal conductivity, and good corrosion resistance. They are widely used in aviation, aerospace, transportation and construction and other fields.

[0003] In the prior art, Chinese patent document CN110404996B proposes a method for mechanical feeding by setting up a feeding track and a feeding claw connected to a feeding cylinder. This method is not only simple in structure and improves efficiency, but also eliminates safety hazards and is highly practical. However, this patent does not solve the problem that existing methods for developing impact-resistant and corrosion-resistant aluminum alloy materials require changing the extrusion die during production according to actual needs. The extrusion press operates at high temperatures during production, and die replacement is mostly done using hoisting equipment. However, when connecting the die to the extrusion press, it is not easy to align the hoisting equipment with the extrusion press, and the angle after alignment may deviate from the required position, requiring manual adjustment. However, manually adjusting the die angle near the extrusion press poses certain safety hazards. Therefore, we disclose a method for developing impact-resistant and corrosion-resistant aluminum alloy materials to meet these requirements. Summary of the Invention

[0008] S3, Anodizing: Forming an oxide film on aluminum alloy;

[0009] S4. Powder coating and fluorocarbon coating: These form a protective coating on the surface of aluminum alloys.

[0010] In the process of producing impact-resistant and corrosion-resistant aluminum alloy materials using the above steps, an extrusion press for forming is also specifically involved. The extrusion press includes an extrusion press body, a first limiting plate fixedly connected to the top of the extrusion press body, a mold slidably connected to the middle of the first limiting plate, a movable frame fixedly connected to the bottom surface of a first limiting block placed at the bottom of the mold, both ends of the movable frame being fixedly connected to the first limiting block, three support columns fixedly connected to the bottom surface of the movable frame, rubber tires rotatably connected to the bottom ends of each support column, a positioning component provided on one side of each support column, the positioning component including a fixed plate, a positioning leaf spring, and a kick; a limit component provided at the bottom end of each support column, the limit component including a moving track, a second limiting plate, and a positioning groove.

[0011] Preferably, a second limiting block is fixedly connected to the middle of the top surface of the first limiting block, and the second limiting groove opened at the bottom of the mold is adapted to the second limiting block.

[0012] Preferably, a fixed frame is fixedly connected to the lower ends of both sides of the extruder body. A third limiting plate slidably connected to the inner cavity of the fixed frame is rotatably connected to a fourth limiting plate. Limiting springs are fixedly connected to both ends of one side of the fourth limiting plate. A connecting plate is fixedly connected to one end of each of the two limiting springs. Limiting rods are fixedly connected to both ends of the connecting plate. A first limiting groove is opened on both sides of the movable frame. The limiting rod is adapted to the first limiting groove and is movably sleeved with the fourth limiting plate.

[0013] Preferably, a ball is movably engaged at the bottom end of the inner cavity of the fixing frame, and the ball is in contact with the bottom surfaces of the third limiting plate and the fourth limiting plate.

[0014] Preferably, when the fourth limiting plate rotates to form a 90-degree angle with the fixed frame, it is adapted to the movable frame, and the fourth limiting plate is slidably connected to the fixed frame.

[0015] Preferably, the side of the limiting rod and the side of the connecting plate are C-shaped, and a first handle is fixedly connected to one end of the fourth limiting plate. The side of the first handle is C-shaped, and the connecting plate is located in the middle of one side of the first handle.

[0016] Preferably, a second handle is fixedly connected to one end of the third limiting plate, and a hole is provided on one side of the second handle.

[0017] Preferably, the support column is rotatably connected to the fixed plate, the two ends of the positioning leaf spring are fixedly connected to the support column and the fixed plate respectively, and a hole is provided in the middle of the kick.

[0019] Preferably, the side of the fixing plate is shaped like a "√", and the positioning leaf spring is an arc-shaped plate.

[0020] Compared with the prior art, the present invention provides a method for developing impact-resistant and corrosion-resistant aluminum alloy materials, which has the following beneficial effects:

[0021] 1. The method for developing this impact-resistant and corrosion-resistant aluminum alloy material uses a single-foot operation limiting component to facilitate the use of the device. Afterwards, the moving frame is pushed until the rubber tire is in contact with the second limiting plate, which restricts the movement of the moving frame and the position of the mold after movement. This facilitates the docking of the mold and the first limiting plate, making operation convenient and ensuring the stable position of the mold after it is connected to the extruder body, which facilitates the extrusion of aluminum alloy. At the same time, the mold on the upper end of the first limiting block on the other side of the moving frame will be pushed to the other side for natural cooling. Moreover, when changing the mold, the operator will not come into contact with the mold that has just been used, avoiding the possibility of the operator being burned by contact with the mold surface with a good temperature.

[0022] 2. The method for developing this impact-resistant and corrosion-resistant aluminum alloy material uses fixed frames on both sides of the extruder body to restrict the position of the moving frame after movement, thereby effectively restricting the position of the die. The fourth limiting plate, together with the limiting spring, restricts the position of the connecting plate, thereby restricting the position of the limiting rod after it is matched with the first limiting groove. The fourth limiting plate restricts the position of the moving frame, preventing the moving frame from moving, stabilizing the position of the die, and ensuring smooth material discharge.

[0023] 3. The method for developing this impact-resistant and corrosion-resistant aluminum alloy material involves the operator tightening their fingers to pull the connecting plate, thereby disconnecting the connection between the limiting rod and the first limiting groove. Then, by pulling the first handle, the fourth limiting plate is rotated so that the fourth limiting plate and the third limiting plate are at the same angle. This allows the fourth and third limiting plates to be moved to the desired position. The operation steps are simple and convenient, and it avoids the operator touching the mold, thus preventing the operator from being burned by the mold which is still warm after use.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a method for developing impact-resistant and corrosion-resistant aluminum alloy materials.

[0033] In a typical embodiment of this application, as shown in Figures 1-6, a method for developing an impact-resistant and corrosion-resistant aluminum alloy material includes the following steps:

[0034] S1. Melting and casting: The materials for making aluminum alloys are put into a melting furnace for melting and then the melted materials are cast into shape.

[0035] S2. Forming: The heated casting rod is extruded from the mold through an extruder to form the aluminum alloy material after melting and casting.

[0036] S3, Anodizing: Forming an oxide film on aluminum alloy;

[0037] S4. Powder coating and fluorocarbon coating: These form a protective coating on the surface of aluminum alloys.

[0038] In the process of using the impact-resistant and corrosion-resistant aluminum alloy material mentioned above, an extrusion press for forming is also specifically involved. The extrusion press includes an extrusion press body 1. A first limiting plate 2 is fixedly connected to the top of the extrusion press body 1. A mold 3 is slidably connected to the middle of the first limiting plate 2. A moving frame 5 is fixedly connected to the bottom surface of a first limiting block 4 placed at the bottom of the mold 3. Both ends of the moving frame 5 are fixedly connected to the first limiting block 4. Three support columns 6 are fixedly connected to the bottom surface of the moving frame 5. Rubber tires 7 are rotatably connected to the bottom of each support column 6. A positioning component is provided on one side of the support column 6. The positioning component includes a fixed plate 10, a positioning leaf spring 11, and a kick 12. A limit component is provided at the bottom of the support column 6. The limit component includes a moving track 8, a second limiting plate 9, and a positioning groove 13. In use... Place the mold 3 to be used on the top of the first limiting block 4. Then, use one foot to operate the limiting component to move the moving frame 5, so that the connection between the support column 6 and the second limiting plate 9 is disconnected, which facilitates the use of the device. Then, push the moving frame 5 to move the support column 6 along the positioning component to one side of the extruder body 1 until the rubber tire 7 is in contact with the second limiting plate 9, restricting the movement of the moving frame 5. At this time, the mold 3 is aligned with the discharge port of the extruder body 1, and the mold 3 is connected to the first limiting plate 2, thereby restricting the position of the mold 3 after it moves, which facilitates the docking of the mold 3 and the first limiting plate 2. The operation is convenient, and the first limiting plate 2 can help the moving frame 5 to restrict the position of the mold 3, so that the position of the mold 3 after it is connected to the extruder body 1 is stable, which facilitates the extrusion of aluminum alloy.

[0039] As a preferred embodiment of this example, referring to Figure 1, a second limiting block 14 is fixedly connected to the middle of the top surface of the first limiting block 4. The second limiting groove 25 opened at the bottom of the mold 3 is adapted to the second limiting block 14. By adapting the second limiting groove 25 to the second limiting block 14, the angle of the mold 3 after placement is limited, preventing the mold 3 from moving during the movement process, thus avoiding deviation in the discharge angle of the aluminum alloy and improving the production qualification rate.

[0040] In a preferred embodiment of this invention, referring to Figure 6, fixed frames 15 are fixedly connected to the lower ends of both sides of the extruder body 1. A third limiting plate 16, which is slidably connected to the inner cavity of the fixed frame 15, is rotatably connected to a fourth limiting plate 17. Limiting springs 18 are fixedly connected to both ends of one side of the fourth limiting plate 17. A connecting plate 19 is fixedly connected to one end of each of the two limiting springs 18. Limiting rods 20 are fixedly connected to both ends of the connecting plate 19. A first limiting groove 21 is provided on both sides of the movable frame 5. The limiting rod 20 is adapted to the first limiting groove 21. The limiting rod 20 is movably sleeved with the fourth limiting plate 17. The fixed frames 15 on both sides of the extruder body 1 allow the movable frame 5 to move to a certain position. The position of the mold 3 is effectively restricted by the slidable connection between the fixed frame 15 and the third limiting plate 16. The fixed frame 15 can restrict the position of the third limiting plate 16, thereby restricting the position of the fourth limiting plate 17. The two ends of the limiting spring 18 are fixedly connected to the fourth limiting plate 17 and the connecting plate 19 respectively, so that the fourth limiting plate 17 and the limiting spring 18 can restrict the position of the connecting plate 19. This restricts the position of the limiting rod 20 after it is adapted to the first limiting groove 21, and restricts the position of the moving frame 5 by the fourth limiting plate 17, preventing the moving frame 5 from moving. This stabilizes the position of the mold 3 and ensures smooth material discharge.

[0041] In a preferred embodiment of this invention, referring to Figure 5, a ball 23 is movably engaged at the bottom of the inner cavity of the fixed frame 15. The ball 23 is in contact with the bottom surfaces of the third limiting plate 16 and the fourth limiting plate 17. When the fourth limiting plate 17 rotates to form a 90-degree angle with the fixed frame 15, it is adapted to the movable frame 5. The fourth limiting plate 17 is slidably connected to the fixed frame 15. The contact between the ball 23 and the third limiting plate 16 and the fourth limiting plate 17 makes it easy for the third limiting plate 16 and the fourth limiting plate 17 to slide within the inner cavity of the fixed frame 15, facilitating operation by the staff. When the fourth limiting plate 17 forms a 90-degree angle with the fixed frame 15, it is adapted to the movable frame 5, resulting in a larger contact area between the fourth limiting plate 17 and the movable frame 5, making the connection between the fourth limiting plate 17 and the movable frame 5 more stable, thereby improving the fixing effect of the movable frame 5 and the position fixing effect of the mold 3.

[0042] In a preferred embodiment of this invention, referring to Figures 4 to 6, the sides of the limiting rod 20 and the connecting plate 19 are C-shaped. A first handle 22 is fixedly connected to one end of the fourth limiting plate 17. The side of the first handle 22 is C-shaped. The connecting plate 19 is located in the middle of one side of the first handle 22. A second handle 24 is fixedly connected to one end of the third limiting plate 16. A hole is provided on one side of the second handle 24. The C-shaped sides of the limiting rod 20 and the connecting plate 19 facilitate pulling the connecting plate 19. The C-shaped sides of the first handle 22 at one end of the fourth limiting plate 17, and the connecting plate 19 being located in the middle of one side of the first handle 22, further facilitate the pulling of the connecting plate 19. The first handle 22 is positioned in the middle, allowing the operator's fingers to pass through the middle of the first handle 22 and the fourth limiting plate 17 when the operator's palm passes through the middle of the first handle 22 and the fourth limiting plate 17. The operator can then tighten their fingers to pull the connecting plate 19, causing the connection between the limiting rod 20 and the first limiting groove 21 to break. By pulling the first handle 22, the operator can rotate the fourth limiting plate 17, causing the fourth limiting plate 17 and the third limiting plate 16 to be at the same angle. The operation steps are simple and convenient, and it can prevent the operator from touching the mold 3, thus avoiding the operator being burned by the mold 3 which is still warm after use.

[0043] In a preferred embodiment of this invention, referring to Figures 5 and 6, the support column 6 is rotatably connected to the fixed plate 10, and both ends of the positioning spring 11 are fixedly connected to the support column 6 and the fixed plate 10 respectively. A hole is provided in the middle of the kick pad 12. The support column 6 is slidably connected to the moving track 8. The positioning groove 13 is adapted to the fixed plate 10, and both ends of the moving track 8 are fixedly connected to the positioning groove 13. One side of the rubber tire 7 is in contact with one side of the second limiting plate 9. The side of the fixed plate 10 is shaped like a "√". The positioning spring 11 is an arc-shaped plate. The positioning spring 11 is connected to both the support column 6 and the fixed plate 10, allowing the positioning spring 11 to restrict the position of the fixed plate 10, thus limiting the fixed position. The position of plate 10 after it is adapted to the positioning groove 13 fixes the position of rubber tire 7 after it is attached to the second limiting plate 9, thus restricting the position of the moving frame 5 after it moves. The hole in the middle of the kick 12 allows the operator to insert his foot into the hole in the middle of the kick 12 and disengage the fixed plate 10 from the positioning groove 13 by kicking the kick 12, reducing the difficulty of operation and making it easier for the operator to use. The sliding connection between the support column 6 and the moving track 8 allows the moving track 8 to restrict the movement position of the support column 6. The attachment of rubber tire 7 to the second limiting plate 9 can reduce the damage to the device caused by the rubber tire 7 hitting the second limiting plate 9 when the operator pushes the moving frame 5 with excessive force, thus improving the service life of the device.

[0044] The working principle of this invention is as follows: In use, the mold 3 to be used is placed on top of the first limiting block 4. Then, the limiting component is operated with one foot to disconnect the support column 6 from the second limiting plate 9, allowing the moving frame 5 to move. This facilitates the use of the device. The moving frame 5 is then pushed until the rubber tire 7 is in contact with the second limiting plate 9, restricting its movement. At this point, the mold 3 is aligned with the discharge port of the extruder body 1, and the mold 3 is connected to the first limiting plate 2, thus limiting the position of the mold 3 after movement. This facilitates docking between the mold 3 and the first limiting plate 2, making operation convenient. The first limiting plate 2 also helps the moving frame 5 restrict the position of the mold 3, ensuring stability after the mold 3 is connected to the extruder body 1, facilitating the extrusion of aluminum alloy. Simultaneously, the mold 3 on the other side of the moving frame 5, above the first limiting block 4, is pushed to the other side of the machine for natural cooling. This prevents workers from touching the freshly used mold 3, avoiding burns from contact with the hot surface of the mold 3.

[0045] The fixed brackets 15 on both sides of the extruder body 1 restrict the position of the movable frame 5 after movement, thereby effectively restricting the position of the mold 3. The fixed brackets 15 restrict the position of the third limiting plate 16, which in turn restricts the position of the fourth limiting plate 17. The fourth limiting plate 17, together with the limiting spring 18, restricts the position of the connecting plate 19, thereby restricting the position of the limiting rod 20 after it is matched with the first limiting groove 21. The fourth limiting plate 17 restricts the position of the movable frame 5, preventing it from moving and ensuring the stability of the mold 3, thus facilitating smooth material discharge.

[0046] The first handle 22 at one end of the fourth limiting plate 17 has a C-shaped side, and the connecting plate 19 is located in the middle of one side of the first handle 22. This allows the operator's fingers to pass through the middle of the first handle 22 and the fourth limiting plate 17 when the operator's palm passes through the middle of the first handle 22 and the fourth limiting plate 17. The operator can tighten their fingers to pull the connecting plate 19, thereby disconnecting the connection between the limiting rod 20 and the first limiting groove 21. Then, by pulling the first handle 22, the fourth limiting plate 17 is rotated, so that the fourth limiting plate 17 and the third limiting plate 16 are at the same angle. The operation steps are simple and more convenient, and it can prevent the operator from touching the mold 3 and avoid the operator being burned by the mold 3 which is still warm after use.

[0047] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
