Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy equipment, and in particular to a method and equipment for producing heat-treatment-free AlSi10MnMg aluminum alloy for automobiles. Background Art

[0002] Automotive heat-treatment-free AlSi10MnMg aluminum alloy is an aluminum alloy material commonly used in the automotive industry, especially suitable for the production of engine parts, wheels, body structures and other parts. The main characteristics of this alloy are good casting performance and mechanical properties, and it does not require complex heat treatment processes (such as solution treatment or aging treatment) to achieve the required performance.

[0003] The existing AlSi10MnMg aluminum alloy has the advantage of strong castability due to its 10% silicon content. However, when cutting it, the high silicon content will cause the aluminum alloy to produce larger and harder chips when being cut. In order to prevent the chips from affecting the cutting effect, the existing technology sets a water spray device on the cutting tool to spray coolant to the raw material to achieve the purpose of cooling and flushing away the chips.

[0004] Although this method can realize the cutting of aluminum alloy, there are still the following problems: if a deeper inner groove needs to be cut into the raw material, the cutting tool will go deep into the raw material for cutting, which may not only cause the coolant to be blocked by the cutting tool and difficult to enter, affecting the cooling effect. Moreover, even if the coolant enters the cutting groove, the coolant's own gravity will push the cutting chips down, and the high temperature generated by cutting will make the cutting chips stick to the cutting tool, making it difficult to discharge the cutting chips, affecting the cutting effect.

DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 2 to Figure 12 As shown, this embodiment proposes a device for producing AlSi10MnMg aluminum alloy for automobiles without heat treatment, and its structure includes a housing 1. The housing 1 used in this embodiment can ensure that the operator is separated from the processing area during the processing of the equipment, preventing the cutting chips generated during the processing from causing harm to the processing personnel.

[0023] The fixing frame 2 in this embodiment is fixedly arranged in the housing 1, and the mounting member 5 is arranged on the fixing frame 2. The transport structure is arranged between the mounting member 5 and the fixing frame 2, so as to make the mounting member 5 move relative to the fixing frame 2. The milling cutter 6 is rotatably arranged on the mounting member 5, the liquid guide groove 65 is arranged in the milling cutter 6, and a plurality of water outlet holes 611 are connected and arranged between the liquid guide groove 65 and the outer wall of the milling cutter 6. The sealing member 651 is slidably arranged in the liquid guide groove 65, the water outlet pipe 7 is fixedly arranged on the sealing member 651, the water storage tank 24 is arranged on the fixing frame 2, and the water storage tank 24 is connected to the water outlet pipe 7. In this embodiment, the liquid guide groove 65 is arranged in the milling cutter 6. The coolant flows out from the water outlet hole 611 through the liquid guide groove 65, which can not only effectively reduce the temperature generated by the milling cutter 6 during rotation, but also can separate the cutting chips generated by the milling cutter 6 from the milling cutter 6 under the drive of water pressure. The possibility of the cutting chips adhering to the milling cutter 6 is effectively reduced.

[0024] In this embodiment, the first drive motor 821 is fixedly arranged on the mounting member 5, and the first gear 81 and the second gear 82 are rotatably arranged on the mounting member 5. The first gear 81 is detachably connected to the milling cutter 6, so as to facilitate the disassembly and replacement of the milling cutter 6. The second gear 82 is fixedly connected to the output shaft of the first drive motor 821, and the first gear 81 and the second gear 82 are meshed. Such a design ensures that the milling cutter 6 can rotate normally for milling processing, and does not affect the movement of the sealing member 651 in the liquid guide groove 65, so as to facilitate the control of the sealing member 651.

[0025] In this embodiment, the first threaded hole 812 is provided on the side wall of the first gear 81, a locking bolt 811 is connected to the inner thread of the first threaded hole 812, and the second threaded hole 66 is provided on the milling cutter 6, and the locking bolt 811 is fixed to the second threaded hole 66 by threaded connection. In this embodiment, the locking bolt 811 is used to lock and fix the milling cutter 6 and the first gear 81, so that when the milling cutter 6 is worn, the milling cutter 6 can be replaced quickly and timely.

[0026] In this embodiment, the first row groove 61, the second row groove 62, the third row groove 63 and the fourth row groove 64 are arranged on the side wall of the milling cutter 6, and the first row groove 61, the second row groove 62, the third row groove 63 and the fourth row groove 64 are wound around the side wall of the milling cutter 6, and each water outlet 611 is respectively arranged in the first row groove 61, the second row groove 62, the third row groove 63 and the fourth row groove 64, and the horizontal height of the water outlet hole 611 close to the liquid guide groove 65 is lower than the horizontal height of the water outlet hole 611 away from the liquid guide groove 65. Such a water outlet design ensures that when the coolant flows out of the water outlet hole 611 during the cutting process, it will be discharged upward along the direction of the first row groove 61, the second row groove 62, the third row groove 63 and the fourth row groove 64, and the generated cutting chips will be discharged away from the milling cutter 6. In this embodiment, the cutting chips generated by the product are discharged through the first discharge groove 61, the second discharge groove 62, the third discharge groove 63 and the fourth discharge groove 64. The cutting chips will be discharged away from the milling cutter 6 along the rotation direction of the milling cutter 6 to avoid the accumulation of cutting chips during the cutting process, causing the cutting chips to stick to the milling cutter 6 and affecting the cutting effect.

[0027] The mounting member 5 in this embodiment includes a first mounting plate 51 and a second mounting plate 52, a connecting plate 53 is fixedly disposed between the first mounting plate 51 and the second mounting plate 52, and a first drive motor 821 is fixedly connected to the second mounting plate 52. This design enables the mounting member 5 to form a sealed box, in which the first drive motor 821 is disposed, and the cutting chips generated by the milling cutter 6 during cutting will not affect its normal operation.

[0028] In this embodiment, the connecting pipe 9 is fixedly arranged at the end of the sealing member 651 away from the liquid guide groove 65, the water outlet pipe 7 is arranged in the connecting pipe 9, the limit plate 91 is fixedly arranged at the end of the connecting pipe 9, and the sliding rod 84 and the screw rod 83 are arranged between the first mounting plate 51 and the second mounting plate 52. The limit plate 91 is slidably connected with the sliding rod 84 to ensure that the limit plate 91 does not slip and deviate. The limit plate 91 is threadedly connected with the screw rod 83, the second drive motor 831 is fixedly arranged on the first mounting plate 51, and the output shaft of the second drive motor 831 is fixedly connected with the screw rod 83. In this embodiment, the screw rod 83 is used to control the movement of the limit plate 91 to achieve the effect of controlling the movement of the seal 651 in the liquid guide groove 65. Since the movement stroke of the screw rod 83 is much greater than the movement stroke of the limit plate 91, it is more accurate and reliable to control the movement of the limit plate 91 by the screw. When ordinary milling is required in this embodiment, the seal 651 can be controlled by rotating the screw to block the water outlet, and the product can be milled by rotating the milling tool. Such a design allows a cleaning nozzle 54 to be set externally to increase the input amount of coolant, thereby better cooling the product during cutting.

[0029] The transport structure in this embodiment includes a first transport frame 3, a first sliding rail 22 and a second sliding rail 23 are arranged on both sides of the fixed frame 2, and are used to prevent the first transport frame 3 from moving out of position. The first transport frame 3 is slidingly connected to the first sliding rail 22 and the second sliding rail 23 at the same time, the third drive motor 32 is fixedly arranged on the first transport frame 3, the first sliding rack 221 is arranged on the side of the fixed frame 2 close to the first sliding rail 22, the third gear 321 is rotatably arranged on the first transport frame 3, the output shaft of the third drive motor 32 is fixedly connected to the third gear 321, and the third gear 321 is meshed with the first sliding rack 221. This is a design for controlling the milling cutter 6 to move along the Y-axis direction. In this embodiment, the third gear 321 is controlled to move on the first sliding rack 221 by the third drive motor 32, which effectively reduces the vibration and unstable factors occurring during the movement, enhances the stability of the overall structure and the reliability of the system, and prolongs the service life of the equipment.

[0030] The third sliding rail 31 in this embodiment is fixedly arranged on the first transport frame 3 to prevent the second transport frame 4 from sliding and deviating. The second sliding rack 33 is fixedly arranged on the first transport frame 3, the second transport frame 4 is arranged on the first transport frame 3, the fourth gear 421 is rotatably arranged on the second transport frame 4, the second transport frame 4 is slidingly connected with the third sliding rail 31, the fourth gear 421 is meshed with the second sliding rack 33, the fourth drive motor 42 is arranged on the second transport frame 4, and the output shaft of the fourth drive motor 42 is fixedly connected with the fourth gear 421. In this embodiment, the second sliding rack 33 is arranged beside the third sliding rail 31, and the second sliding rack 33 and the third sliding rail 31 are parallel to each other, which saves space to a great extent and facilitates the installation and commissioning of the first transport frame 3.

[0031] The second transport frame 4 in this embodiment is provided with a telescopic member 41, the fixed end of the telescopic member 41 is fixedly connected to the second transport frame 4, and the telescopic end of the telescopic member 41 is fixedly connected to the mounting member 5. The cleaning nozzle 54 is arranged on the mounting member 5, and is used to increase the input amount of the coolant to the milling cutter 6 when the milling cutter 6 is processing ordinary products (i.e., when deep grooves are not processed), thereby further strengthening the cooling effect on the milling cutter 6. The operation port 11 is arranged on the housing 1, and the sealing door 12 is slidably arranged on the operation port 11. In this embodiment, the operator can clamp and fix the product on the fixed frame 2 through the operation port 11, and the sealing door 12 is used to prevent the cutting chips from splashing to avoid hurting the operator. A plurality of mounting brackets 21 are fixedly arranged on the fixed frame 2, and the cross section of the mounting bracket 21 is an "I"-shaped structure, which is used to facilitate the installation of a fixed clamping mechanism (used to clamp and fix the workpiece to facilitate milling processing thereof). The telescopic member 41 used in this embodiment is preferably a hydraulic cylinder or a cylinder, wherein the hydraulic cylinder and the cylinder are both prior art and are not described in detail in this embodiment.

[0032] Another object of the present invention is to provide a method for producing a heat-treatment-free AlSi10MnMg aluminum alloy for automobiles, the steps of which are as follows: S1: 9.5% to 11.5% silicon, 0.3% to 0.6% manganese, 0.3% to 0.7% magnesium, 0.5% to 0.1% iron, copper, titanium mixture, and the rest aluminum are mixed to obtain the production raw material. Silicon is used in this embodiment to improve the castability and corrosion resistance of the aluminum alloy. Manganese enhances the strength and corrosion resistance of the alloy. Magnesium improves strength and high temperature resistance through solid solution strengthening. A small amount of iron and copper are used to improve strength. Titanium plays a role in grain refinement and improves the mechanical properties of the alloy.

[0033] S2: Put the raw material into the melting furnace, adjust the temperature in the furnace to 750℃~800℃, and melt for 30 minutes to 1 hour. This design can effectively ensure that the alloying elements of the aluminum alloy are completely dissolved and the composition is uniform, which helps to obtain high-quality aluminum alloy products. While controlling the temperature and time, it can reduce oxidation loss and pore defects, improve the physical and mechanical properties of the aluminum alloy, and ensure that it has good processability and mechanical properties in subsequent casting or processing.

[0034] S3: Blow argon or nitrogen into the furnace for 30 minutes to 1 hour to ensure that the bubbles in the molten metal are discharged. Blowing argon or nitrogen into the furnace for gas removal can effectively remove gas impurities (such as hydrogen, oxygen, etc.) in the molten metal, thereby improving the density and quality of the casting, reducing pore defects, and improving the physical and mechanical properties of the alloy. This process can not only improve the fluidity and filling properties of aluminum alloys and other metals, but also prevent metal oxidation and ensure the purity and stability of the metal.

[0035] S4: The raw material obtained in step S3 is introduced into the mold of the casting equipment, the casting temperature is adjusted to 700℃~750℃, and grain refining particles (such as titanium or boron alloy) are added for casting; after the raw material is introduced into the mold, the casting temperature is adjusted and grain refining particles are added, which can refine the grains of the casting, significantly improve the mechanical properties, corrosion resistance and density of the casting, reduce casting defects, and improve casting quality and efficiency. Grain refiners such as titanium and boron alloys play a key role in this process, helping to optimize the structure and properties of the metal and ensure that the casting meets higher use requirements.

[0036] S5: Remove the casting from the casting equipment, let the casting cool naturally to room temperature, and then place the casting into the equipment for producing AlSi10MnMg aluminum alloy for automotive use without heat treatment, and perform cutting, grinding, drilling and other processing to complete the processing. By cooling the casting naturally to room temperature and performing cutting, grinding, drilling and other processing, especially in the process of producing AlSi10MnMg aluminum alloy for automotive use without heat treatment, it can effectively reduce internal stress, improve surface quality and processing accuracy, reduce the production cost and cycle of heat treatment, and optimize the mechanical properties of the casting to ensure that it meets automotive standards. In addition, this process helps to improve production efficiency and reduce casting defects, thereby ensuring the high quality of the final product.

[0037] When it is necessary to process deep grooves on the aluminum alloy, start the second drive motor 831 to move the seal 651 away from the water outlet. At this time, water is supplied to the water outlet pipe 7 through the water storage tank 24, and then start the first drive motor 821. Driven by the first gear 81 and the second gear 82, the milling cutter 6 rotates, and then the third drive motor 32, the fourth drive motor 42 and the telescopic member 41 are used to control the movement of the milling cutter 6 to achieve deep groove processing on the aluminum alloy; when it is necessary to perform ordinary milling or shallow groove processing on the aluminum alloy, start the second drive motor 831 in the reverse direction to move the seal 651 toward the water outlet, so that the sealant blocks the water outlet, and then the first drive motor 821, the third drive motor 32 and the fourth drive motor 42 are used to control the movement of the milling cutter 6 to achieve processing of the aluminum alloy.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
