Description

Technical Field

[0001] This utility model relates to the field of milling equipment technology, specifically to a milling machine for alloy aluminum billets. Background Technology

[0002] During continuous casting, the liquid metal (molten aluminum) gradually cools and crystallizes into a solid aluminum alloy billet (bar). This transformation process easily leads to localized surface oxidation, inclusions, and surface cracks. To address these casting defects and improve the quality of the aluminum alloy billet (bar) before it enters the continuous rolling mill, an online continuous milling machine needs to be installed between the continuous casting machine and the continuous rolling mill to simultaneously mill the aluminum alloy billet (bar) cast in the continuous casting machine. The main challenges of existing continuous milling machines in milling operations are concentrated in the following aspects: Because the aluminum billet is at a high temperature and relatively soft after exiting the continuous casting machine, it undergoes significant deformation before entering the continuous milling machine. This deformation occurs along both the vertical Z-axis and the horizontal Y-axis, and large deformations in these two directions are detrimental to the control of the aluminum billet's cross-section after machining. Even after straightening, the aluminum billet surface remains uneven, making it difficult to control the cutting amount and resulting in significant fluctuations in the machined surface. The high temperature and softness of the aluminum billet frequently cause tool sticking, and prolonged machining requires tool cooling; otherwise, tool sticking will significantly impact the surface roughness of the machined surface. Furthermore, high-temperature machining... The lifespan of the cutting tools will be affected; existing continuous milling machines are also equipped with chip collection devices, most of which use negative pressure devices to suck away the generated chips. If a negative pressure device is used to suck away aluminum chips near the milling cutter, it will also absorb the coolant on the milling cutter while removing the aluminum chips, which will greatly affect the cooling effect of the milling cutter assembly and make it easier for the chip to stick; the temperature of aluminum chips after high-speed cutting is relatively high, and if they fall onto the machined surface, they will stick together and be difficult to clean; the aluminum billet speed is relatively high, which can easily cause the surface roughness of the machined parts to be too high, and high-speed rotating cutting tools are required to meet the requirements.

Detailed Implementation

[0016] To make the technical solutions and advantages of the embodiments of this utility model clearer, the following description is provided in conjunction with the appendix. Figure 1-10 The exemplary embodiments of the present invention will be described in further detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0017] In the process of realizing this utility model, the inventors discovered that the main difficulties of existing continuous milling machines in milling operations are concentrated in the following aspects: Because the aluminum billet is at a high temperature and relatively soft after exiting the continuous casting machine, it undergoes significant deformation before entering the continuous milling machine. This deformation occurs along the vertical Z-axis and the horizontal Y-axis, both of which hinder the control of the billet's cross-section after machining. Even after straightening, the billet surface remains uneven, making it difficult to control the cutting amount and resulting in significant fluctuations in the machined surface. The high temperature and softness of the aluminum billet frequently cause tool sticking, requiring cooling of the tool during prolonged machining to prevent significant impact on surface roughness. High-temperature machining also affects tool life. High-speed cutting of aluminum chips results in high temperatures, which can cause them to stick together on the machined surface, making them difficult to clean. The high billet speed can easily lead to excessively high surface roughness, necessitating high-speed tool rotation to achieve the desired result.

[0018] To address the above problems, this utility model provides an alloy aluminum billet milling machine, such as... Figure 1 , Figure 2 As shown, it includes: The milling machine base 10 includes a base plate, a front plate, a rear plate and a top plate. The milling machine base 10 is equipped with a power supply mechanism to provide power to the electrical equipment inside the alloy aluminum billet milling machine. The correction mechanism 20 includes multiple horizontally arranged correction guide wheels 201, which are rotatably mounted on the top of the milling machine base 10. The alloy aluminum billet 70 is rolled on the multiple correction guide wheels 201. The pressing mechanism 30 includes a pressing base 301 disposed on one side of the milling machine base 10. A pressing component 302 is movably disposed on the pressing base 301. The pressing component 302 is connected to the drive end of the pressing height adjustment component 303. Under the action of the pressing height adjustment component 303, the pressing component 302 can adjust its height relative to the pressing base 301. The working surface of the pressing component 302 is located above the straightening guide wheel 201. The milling mechanism 40 includes a milling frame 401 disposed on the other side of the milling machine base 10. The milling frame 401 includes a front plate, a rear plate, and a top plate. A first milling support plate 402 is movably disposed inside the milling frame 401. The first milling support plate 402 is connected to the drive end of the first milling height adjustment component 403. Under the action of the first milling height adjustment component 403, the height of the first milling support plate 402 can be adjusted within the milling frame 401. A first milling pressure roller assembly 404 and a milling cutter assembly 405 are installed at the bottom of the first milling support plate 402. The first milling pressure roller assembly 404 is located between the milling cutter assembly 405 and the pressing mechanism 30. The working surfaces of the milling cutter assembly 405 and the first milling pressure roller assembly 404 are located above the straightening guide wheel 201, and the height of the working surface of the milling cutter assembly 405 is lower than the height of the working surface of the first milling pressure roller assembly 404. The outer casing 80, milling machine base 10, straightening mechanism 20, pressing mechanism 30, milling mechanism 40 and other mechanisms together constitute the internal structure of the alloy aluminum billet milling machine. The outer casing 80 is set outside the internal structure of the alloy aluminum billet milling machine to protect the internal structure and can partially isolate the negative impact of high temperature and dust on the internal structure. The side wall of the outer casing 80 is provided with an openable door, which makes it convenient for workers to open the door to regularly inspect and maintain the internal structure of the alloy aluminum billet milling machine.

[0019] In practice, during the milling process, the overall operating temperature of the aluminum alloy billet 70 is between 350-400°C. The milling cutter only needs to mill the upper surface area of ​​the aluminum alloy billet 70, with a thickness within the range of 0.5mm + 0.1-0.2mm. When not in use, the pressing assembly 302 and the first milling support plate 402 are raised to the preset initial position, leaving a gap of ≥80mm between them and the surface of the aluminum alloy billet 70. This ensures that other billets can pass through normally and that the aluminum alloy billet 70 can be removed promptly in case of malfunction. When in use, the aluminum alloy billet 70 exits from the continuous casting machine. After arriving, the aluminum billet 70 rolls forward on the straightening guide wheel 201. After the first end of the aluminum billet 70 passes the pressing mechanism 30, the pressing height adjustment component 303 is activated, driving the pressing component 302 downwards to the set processing position. This, in conjunction with the straightening mechanism 20, presses and straightens the aluminum billet 70. Simultaneously, the first milling height adjustment component 403 is activated, driving the first milling support plate 402 downwards. The first milling pressure roller assembly 404 contacts the upper surface of the aluminum billet 70 before the milling cutter assembly 405. The milling cutter assembly 405 then activates, milling the upper surface of the aluminum billet 70. After processing, the pressing component 302 and the first milling support plate 402 are raised to their initial positions, and the remaining aluminum billet 70 is removed from the milling machine, at which point the milling machine stops working.

[0020] The alloy aluminum billet milling machine provided by this utility model uses a pressing component 302 in conjunction with a straightening mechanism 20 to press and straighten the alloy aluminum billet 70 simultaneously, integrating pressing, straightening, and milling. By setting the first milling roller assembly 404 and the milling cutter assembly 405 on the same height-adjustable milling plate, the height difference between the working surfaces of the first milling roller assembly 404 and the milling cutter assembly 405 is used to control the milling amount, enabling the milling cutter assembly 405 to perform follow-up processing with the first milling roller assembly 404. This ensures that the machined surface of the alloy aluminum billet 70 does not have large fluctuations, and that the oxide scale on the surface of the alloy aluminum billet 70 can be uniformly removed. Through stable control of the milling amount, the milling cutter assembly 405 is protected during the processing, while the cutting thickness is uniform, and it is not easy to generate fine flying chips. The chips are relatively continuous and do not easily fall onto the machined surface. Furthermore, the continuous cutting chips are easier to clean.

[0021] As a preferred option, such as Figure 3 , Figure 4As shown, the milling mechanism 40 also includes: Multiple guide rails 406 are vertically installed on the inner sides of the front and rear plates of the milling frame 401. The two sides of the first milling support plate 402 are slidably connected to the guide rails 406 through mounting sliders 407. The second milling support plate 408 is disposed on the side of the first milling support plate 402 away from the pressing mechanism 30. Both sides of the second milling support plate 408 are slidably connected to the guide rail 406 through mounting sliders 407. The second milling support plate 408 is connected to the drive end of the second milling height adjustment component 409. Under the action of the second milling height adjustment component 409, the height of the second milling support plate 408 can be adjusted within the milling frame 401. The second milling pressure roller assembly 410 is installed at the bottom of the second milling support plate 408, and the working surface of the second milling pressure roller assembly 410 is located above the straightening guide roller 201; A rotating scraper, positioned between the milling cutter assembly 405 and the second milling roller assembly 408, sweeps away aluminum chips from the surface of the cut aluminum alloy billet.

[0022] Specifically, the first milling assembly pressure roller assembly 404 includes a pressure roller housing, which is installed at the bottom of the first milling support plate 402. Bearings are installed at both ends of the inner wall of the pressure roller housing. The milling pressure shaft is rotatably disposed in the pressure roller housing through the bearings. The end of the milling pressure shaft that extends out of the front plate of the milling frame 401 is equipped with a first milling pressure roller 4041. The surface of the first milling pressure roller 4041 that contacts the alloy aluminum billet 70 is the working surface of the first milling assembly pressure roller assembly 404. The second milling roller assembly 410 includes a second milling roller 4101, and the rest of the structure is basically the same as that of the first milling roller assembly 404, which will not be described in detail here. The first milling height adjustment component 403 can be the first height adjustment cylinder 4031, and the output end of the first height adjustment cylinder 4031 is the driving end of the first milling height adjustment component 403. The second milling height adjustment component 409 can be the second height adjustment cylinder 4091, and the output end of the second height adjustment cylinder 4091 is the driving end of the second milling height adjustment component 409. The first height adjustment cylinder 4031 and the second height adjustment cylinder 4091 are located on the top of the milling frame 401 and do not occupy the space of the aluminum chip handling mechanism 60 inside the milling machine base 10.

[0023] In practice, the second milling pressure roller assembly 410 presses down synchronously with the first milling component pressure roller assembly 404 when it presses down, and lifts synchronously with it when it lifts up. The first milling component pressure roller assembly 404 and the second milling pressure roller assembly 410 are located on both sides of the milling cutter assembly 405, respectively pressing the alloy aluminum billet 70 before and after milling. With the help of the straightening guide rollers 201 below them, the stability of the alloy aluminum billet 70 before and after processing by the milling cutter assembly 405 is ensured, so that the milling cutter assembly 405 is protected during the processing, and the cutting accuracy is further improved.

[0024] As a preferred option, such as Figure 6 , Figure 7 As shown, the pressing mechanism 30 includes multiple sets of pressing components 302 and pressing height adjustment components 303 corresponding to the number of pressing components; The pressure-down assembly 302 includes: The thick-walled tube seat 3021 has its outer walls hinged at both ends to the top of the pressing base 301; Bearings are installed at both ends of the inner wall of the lower pressure wheel shaft 3022 and the thick-walled tube seat 3021. The lower pressure wheel shaft 3022 is rotatably mounted in the thick-walled tube seat 3021 through the bearings. Sealing gaskets and cover plates are sequentially provided on the outer sides of the bearings at both ends of the thick-walled tube seat 3021. The pressing flat roller 3023 has one end of the pressing roller shaft 3022 extending out of the thick-walled tube seat 3021 and connected to the pressing flat roller 3023. The contact surface between the pressing flat roller 3023 and the alloy aluminum billet 70 is the working surface of the pressing assembly 302. The downward pressure adjustment component 303 includes: The hydraulic cylinder base plate 3031 is located inside the milling machine base 10 and below the lower pressure base 301; The hydraulic cylinder 3032 is hinged at its bottom to the hydraulic cylinder base plate 3031. The output end of the hydraulic cylinder 3032 is the driving end of the pressure adjustment component 303. The middle part of the pressure base 301 is provided with an opening through which the hydraulic cylinder 3032 can pass. After the output end of the hydraulic cylinder 3032 passes through the opening, it is hinged to the outer wall of the thick-walled tube seat 3021.

[0025] In specific implementation, two sets of pressing components 302 and corresponding pressing height adjustment components 303 are set, and the pressing components 302 of the two sets of components press down simultaneously; correspondingly, the lower correction guide wheels 201 are preferably set to three, and the two pressing flat wheels 3023 after pressing are respectively located in the upper middle part of the two adjacent correction guide wheels 201. This preferred arrangement can better press the alloy aluminum billet 70.

[0026] As a preferred option, such as Figure 9 As shown, the straightening guide wheel 201 has a groove, the outline of which matches the shape of the lower half of the cross-section of the alloy aluminum billet 70, such as... Figure 8 As shown, the straightening guide wheel 201 includes a short-axis straightening guide wheel 202 and a long-axis straightening guide wheel 203; A short-axis straightening guide wheel 202 is disposed on one side of the pressing mechanism 30, and includes: The guide wheel base 204 is installed on the top of the milling machine base 10. A straightening load-bearing base plate is installed on the top of the straightening load-bearing base plate. An opening is provided in the middle of the straightening load-bearing base plate for the hydraulic cylinder to pass through. The guide wheel base 204 is located on one side of the opening on the straightening load-bearing base plate. The top of the guide wheel base 204 is connected to the lower pressure base 301. The guide wheel base 204 includes a front vertical plate 205, a rear vertical plate 206 and a short bushing 207. The outer walls of both ends of the short bushing 207 are connected to the front vertical plate 205 and the rear vertical plate 206 respectively. A straightening rear side plate is provided on the other side of the opening on the straightening load-bearing base plate. The bottom of the lower pressure base 301 is connected to the straightening rear side plate, the front vertical plate 205 and the rear vertical plate 206 and is located above the milling machine base 10. Bearings are installed at both ends of the inner wall of the short shaft 208 and the short shaft sleeve 207. The short shaft 208 is rotatably mounted in the short shaft sleeve 207 through the bearings. One end of the short shaft 208 extends out of the short shaft sleeve 207 and is connected to the short shaft straightening guide wheel 202. A long-axis straightening guide wheel 203 is disposed on one side of the milling mechanism 40, including: The long shaft sleeve 209 is set inside the milling machine base 10, and the two ends of the long shaft sleeve 209 are connected to the front and rear plates of the milling machine base 10, respectively. The long shaft 210 is rotatably mounted inside the long shaft sleeve 209, with one end of the long shaft 210 extending out of the long shaft sleeve 209 and connected to the long shaft straightening guide wheel 203.

[0027] In specific implementation, since the downward adjustment component 303 in the above scheme occupies the internal space of one side of the downward pressing mechanism 30 of the milling machine base 10, in order to ensure that the axle of the straightening guide wheel 201 on this side and the normal operation of the hydraulic cylinder 3032 are not affected, and also to increase the utilization rate of the internal space of the milling machine base 10, the straightening guide wheel 202 on one side of the downward pressing mechanism 30 is set as a short-axis straightening guide wheel 202; the inner groove shape of the straightening guide wheel 201 is adapted to the shape of the lower half of the alloy aluminum billet 70, and the bottom surface and two sides of the alloy aluminum billet 70 are limited to achieve straightening.

[0028] As a preferred option, such as Figure 4 As shown, the milling cutter assembly 405 includes: The milling cutter motor 4051 is located at the bottom of the first milling support plate 402; The corn kernel milling cutter 4052 is connected to the spindle of the milling cutter motor 4051. The milling cutter spindle of the corn kernel milling cutter 4052 is centrally cooled, and the internal circulating medium of the milling cutter spindle is connected to the external internal cooling circulation device. The contact surface between the corn kernel milling cutter 4052 and the alloy aluminum billet 70 is the working surface of the milling cutter assembly 405.

[0029] In specific implementation, in the above embodiments, the pressing mechanism 30, in conjunction with the straightening mechanism 20, presses and straightens the alloy aluminum billet 70, and coordinates with the follow-up processing of the milling cutter assembly 405 and the first milling pressure roller assembly 404. By precisely controlling the cutting amount, the chips at the milling cutter are easier to clean, eliminating the need to use coolant to flush the chips at the milling cutter. Therefore, in this invention, a milling cutter shaft center cooling solution can replace the coolant spraying solution to cool the milling cutter. The corn kernel milling cutter 4052 is connected to the motor spindle via a BT40 tool holder. The milling cutter motor 4051 can preferably be a variable frequency servo motor. The maximum speed of the milling cutter is 12000 rpm. Since the aluminum billet speed is relatively fast, 11~12 m / min (200 mm / s), this speed is relatively high for machining and can easily result in excessively high surface roughness of the machined parts. However, a high-speed rotating tool can meet the machining requirements. The milling cutter spindle adopts a water-cooled spindle or an air-cooled spindle, preferably a water-cooled spindle. When the milling cutter assembly 405 is started, the spindle of the milling cutter motor 4051 rotates, driving the corn kernel milling cutter 4052 to perform reverse milling on the upper surface of the alloy aluminum billet 70. At the same time, the internal cooling circulation device is started. The central cooling allows the corn kernel milling cutter 4052 to be kept cool and in working condition. Through heat conduction, some of the aluminum chips generated by the corn kernel milling cutter 4052 are cooled, so that the aluminum chips fall off more evenly in sheets. In conjunction with the water-cooled spindle, the milling cutter sticks to the tool.

[0030] As a preferred option, such as Figure 10 As shown, the alloy aluminum billet milling machine also includes an aluminum chip handling mechanism 60, comprising: A chip guard 601 is provided. Vertical stroke slots 411 are respectively provided on the front plate of the milling frame 401 corresponding to the first milling pressure roller assembly 404, the milling assembly 405, and the second milling pressure roller assembly 410. The chip guard 601 covers the vertical stroke slots 411 corresponding to the milling assembly 405. Openings for alloy aluminum billet strips 70 to pass through are provided on both sides of the chip guard 601. A chip outlet is provided at the bottom of the chip guard 601. A transparent window is provided on the chip guard 601 to facilitate observation of the processing status of the milling cutter assembly 405 at any time. An openable door is provided on the chip guard 601 to facilitate replacement of the milling cutter. The vertical stroke slots 411 facilitate the replacement of the first milling pressure roller assembly 404, the milling assembly 405, and the second milling pressure roller assembly 410. The aluminum chip receiving trough 602 is wider at the top and narrower at the bottom, with its side walls inclined. The aluminum chip receiving trough 602 is set on the front plate of the milling machine base 10. The aluminum chip receiving trough 602 covers the straightening component 20 and has its opening facing upward. The bottom of the aluminum chip receiving trough 602 is provided with a discharge port. The aluminum chip collection cover 603 is wider at the top and narrower at the bottom, with its side walls set at an angle. The aluminum chip collection cover 603 is set at the bottom of the milling machine base 10. The inlet of the aluminum chip collection cover 603 is connected to the outlet of the aluminum chip receiving groove 602. The bottom of the aluminum chip collection cover 603 is provided with a chip discharge port. An aluminum shavings collection box 604 is located on one side of the aluminum shavings collection cover 603 at the bottom of the milling machine base 10. The inlet of the aluminum shavings collection box 604 is connected to the shavings discharge port of the aluminum shavings collection cover 603 through a pipe. The chip removal fan 605 is installed inside the milling machine base 10. The air inlet of the chip removal fan 605 is connected to the outlet of the aluminum chip collection box 604 through an air inlet pipe. A filter screen is installed at the outlet of the aluminum chip collection box 604. The air outlet of the chip removal fan 605 is connected to the outside through an air outlet pipe.

[0031] In specific implementation, the aluminum chips generated during the processing mainly fall into the following categories: During the straightening and pressing process, the oxide scale on the surface of the alloy aluminum billet 70 is crushed or scraped off, and an aluminum chip receiving groove 602 with an opening that can cover all the straightening guide wheels 201 is set accordingly; Most of the aluminum chips are generated by milling, and an aluminum chip blocking cover 601 is set on the outside of the milling cutter assembly 405. The relatively continuous cutting blades generated by milling the surface of the alloy aluminum billet 70 fall into the aluminum chip receiving groove 602 below by their own weight, and the flying chips fly towards the side wall of the aluminum chip blocking cover 601 and fall off. After the milling cutter assembly 405 is started, the chip removal fan 605 is started simultaneously. Under the action of the chip removal fan 605, the flowing air passes from the aluminum chip receiving trough 602 through the aluminum chip collection cover 603, carrying away the aluminum chips in the aluminum chip collection cover 603. The air mixed with aluminum chips enters the collection box 604, where the aluminum chips settle to the bottom and separate from the flowing air. Finally, the flowing air enters the chip removal fan 605 and is discharged from the outlet of the chip removal fan 605. The aluminum chip collection box 604 can be taken out and put in from the milling machine base 10, and the aluminum chips accumulated in the aluminum chip collection box 604 are emptied periodically.

[0032] As a preferred option, such as Figure 5 As shown, an air-cooled chip removal assembly 606 is provided inside the aluminum chip shield 603. The air-cooled chip removal assembly 606 includes: The cold air inlet nozzle 6061 is located on the side wall of the aluminum chip shield 603. The air inlet of the cold air inlet nozzle 6061 is connected to the air outlet of the external cold air fan. The air outlet of the cold air inlet nozzle 6061 is directly opposite the upper part of the corn kernel milling cutter 4052. The cold air outlet 6062 is located on the side wall of the aluminum chip shield 603 away from the cold air inlet nozzle 6061, and the cold air outlet 6062 is positioned directly opposite the air outlet of the cold air inlet nozzle 6061.

[0033] In practice, the applicant discovered that in the traditional method of using coolant to flush chips from the milling cutter, it is impossible to simultaneously use a negative pressure fan or other collection device to remove the generated milling chips. This is because removing aluminum chips also absorbs the coolant from the milling cutter, greatly affecting the cooling effect of the milling cutter assembly 405 and making it more prone to chip sticking. To address the above problems, this utility model uses chip blowing instead of chip suction. After the milling cutter assembly 405 is started, a cold air fan is started simultaneously to cool the milling cutter. Preferably, the outlet of the cold air inlet 6061 is directly opposite the upper part of the corn kernel milling cutter 4052, and the outlet of the cold air inlet 6061 is tilted upward to avoid the cold air blowing directly onto the alloy aluminum billet 70. Excessive temperature difference could accelerate surface oxidation or internal stress changes, which may lead to a long-term decline in material properties. The cold air outlet is positioned directly opposite the outlet of the cold air inlet 6061 to ensure that the cold air only passes through the upper part of the corn kernel milling cutter 4052. The air-cooled chip removal assembly 606 works in conjunction with the internally cooled spindle to further cool the milling cutter, thereby protecting the tool.

[0034] As a preferred option, such as Figure 5 As shown, multiple aluminum chip nozzles 607 are installed on the front plate of the milling machine base 10. The air inlet of the aluminum chip nozzle 607 is connected to the air outlet of the external fan, and the air outlet of the aluminum chip nozzle 607 is directly facing the surface of the alloy aluminum billet 70.

[0035] In specific implementation, this utility model adopts an aluminum chip blowing nozzle 607 to assist in blowing. After the milling cutter assembly 405 is started, the blower is started simultaneously. The aluminum chip blowing nozzle 607 can blow away the chips that fall onto the surface of the alloy aluminum billet 70. The blown chips fall into the aluminum chip receiving groove 602 below the alloy aluminum billet 70 and enter the aluminum chip processing mechanism 60 for unified recycling. The aluminum chip blowing nozzle 607 further ensures that the aluminum chips are recycled cleanly, while ensuring the flatness of the processed surface of the alloy aluminum billet 70.

[0036] As a preferred option, such as Figure 10 As shown, a vibration motor 608 is installed on the side wall of the aluminum chip collection hood 603.

[0037] In practice, after the milling cutter assembly 405 is started, the vibration motor 608 is started simultaneously. Because aluminum chips are generally spiral in structure, they tend to accumulate at the chip discharge port of the aluminum chip collection cover 603. When the vibration motor 608 is working, it vibrates the side wall of the chip collection cover 603, which disperses the accumulated aluminum chips and allows them to be smoothly discharged from the chip discharge port along the side wall of the aluminum chip collection cover 603.

[0038] The alloy aluminum billet milling machine provided in this embodiment is mainly used on five-series alloy billets. Combined with a continuous casting and rolling mill production line, it performs online surface treatment. The entire milling machine system operates synchronously with the rolling mill system, ensuring synchronization with the main rolling mill and casting machine. The alloy aluminum billet milling machine provided in this embodiment, through the combined action of the pressing component, the straightening guide wheel, and the milling component pressure rollers located on both sides of the milling cutter component, simultaneously presses and straightens the alloy aluminum billet, preventing deformation of the billet from affecting subsequent processing. It creatively places the first milling pressure roller assembly and the milling cutter assembly on the same height-adjustable milling plate, using the height difference between the working surfaces of the first milling pressure roller assembly and the milling cutter assembly to control the milling amount, enabling the milling cutter assembly to perform follow-up processing with the first milling pressure roller assembly. The milling cutter spindle adopts an internally cooled spindle, abandoning the traditional method of using a negative pressure device to suck up aluminum chips, and instead using an air-cooled chip blowing component to cool the milling cutter. Simultaneously, aluminum chips on the milling cutter are blown into the aluminum chip handling mechanism; larger aluminum chips fall into the aluminum chip receiving trough under their own weight and the action of the air-cooled chip blowing component; aluminum chips that fall on the surface of the alloy aluminum billet are blown into the aluminum chip receiving trough by the aluminum chip nozzle; the aluminum chip baffle prevents aluminum chips from splashing everywhere; the aluminum chip collection hood is connected to the chip exhaust fan to suck the aluminum chips into the collection box; the short shaft straightening guide wheel and the downward pressure height adjustment component are set on the same side inside the milling machine base, and their normal operation does not affect each other; the milling height adjustment component is set on the top of the milling frame to avoid occupying the space of the aluminum chip handling mechanism below; through the reasonable planning of the internal space of the milling machine base, the volume of the alloy aluminum billet milling machine is reduced and the space utilization rate is improved. The alloy aluminum billet milling machine provided by this utility model effectively solves the problems of aluminum billet deformation correction and clamping, milling cutter cooling, high-temperature aluminum chip collection and treatment, and difficulty in controlling the cutting amount due to the high temperature and soft texture of the aluminum billet. It enables continuous milling of aluminum billets to run for a long time and has strong practicality.
