Abstract
Description
Technical Field
[0001] This invention belongs to the field of aluminum ingot production and processing technology, and specifically relates to a cutting device for the production of recycled aluminum ingots. Background Technology
[0002] Recycled aluminum is an aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum and aluminum alloy materials or aluminum-containing waste. However, recycled aluminum ingots have low purity (95%-99%), many impurities (containing iron, copper, silicon, and even small amounts of non-metallic impurities such as plastic residue and oxide scale, and uneven distribution), and large density fluctuations (due to poor control of melting temperature / refining process, which may result in porosity, air holes, or local "hard spots" (such as iron alloy particles)). The material is "uneven and has many impurities," making recycled aluminum ingots easy to be blocked by hard spots when cutting, resulting in unstable force and causing wavy lines and chipped edges on the cut surface, requiring an additional "grinding / milling" process. Summary of the Invention
[0003] In view of this, the present invention discloses a cutting device for the production of recycled aluminum ingots, the purpose of which is to address the problem that the cut surface of recycled aluminum ingots is prone to wavy patterns and chipped edges, requiring additional grinding.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A cutting device for producing recycled aluminum ingots includes a worktable with an installation groove. A cutting device and a grinding device are respectively installed at both ends of the installation groove. The cutting device includes a swing arm hinged to the worktable, with a torsion spring at the hinge point, and a cutting tool at the end of the swing arm. The grinding device includes a power cylinder perpendicular to the aluminum ingot conveying direction, with a support frame at the output end of the power cylinder, and grinding structures on both sides of the support frame. Two conveying structures for conveying aluminum ingots are symmetrically arranged on the worktable about the installation groove.
[0006] In this solution, aluminum ingots are conveyed and temporarily fixed by conveyor structures at both ends, and the aluminum ingot cutting area is placed in the installation groove. Then, the cutting is performed by a swing arm with a cutter at the end of the swing arm. The aluminum ingot is then moved forward a distance by the conveyor structure corresponding to the cut aluminum ingot, creating a gap between the two aluminum ingots. At this point, the support frame is driven by a power cylinder, and the grinding structure on the support frame grinds the cut surfaces of the aluminum ingots on both sides, making the cut surfaces of the recycled aluminum ingots smoother and flatter, which is beneficial for subsequent processing. After grinding, the cut aluminum ingots are conveyed away by two conveyor structures, and the aluminum ingot to be cut is moved to the cutting area facing the installation groove.
[0007] Furthermore, the polishing structure includes an adjusting cylinder vertically mounted on a support frame, a base vertically slidably connected to the support frame at the output end of the adjusting cylinder, a rotating seat horizontally perpendicular to the support frame rotatably mounted on the base, and a rotary motor for driving the rotating seat to rotate on the base; a vertically mounted support rod is hinged to the rotating seat, and a torsion motor for pushing the support rod to deflect is mounted on the rotating seat; an annular abrasive block is coaxially rotatably connected to each support rod, and a drive motor for driving the abrasive wheel to rotate is mounted on each support rod.
[0008] In this solution, when the cut surface needs grinding, the support rod is driven to swing vertically by a torsion motor, and the aluminum ingot is moved by a conveying structure so that the end face of the aluminum ingot can contact the grinding wheel on the support rod. At this time, the grinding wheel is driven by a power cylinder and a support frame to grind the cut end face of the aluminum ingot. When the periphery of the end of the aluminum ingot needs grinding, the support rod is driven to swing horizontally by a torsion motor, and the base is driven to slide by an adjusting cylinder, so that the grinding wheel on the end face of the support rod contacts the horizontal surface of the end of the aluminum ingot. At this time, the grinding wheel is driven by a power cylinder and a support frame to grind the horizontal surface of the periphery of the aluminum ingot. Then, the grinding wheel is driven by a power cylinder and a support frame to move to contact the vertical surface of the periphery of the aluminum ingot. At this time, the grinding wheel is driven to move vertically by an adjusting cylinder to grind the vertical surface of the periphery of the aluminum ingot. Furthermore, when the end face of the aluminum ingot requires chamfering, a torsion motor is used to deflect the support rod to an inclined position. The position of the support rod is then adjusted using a power cylinder and an adjustment cylinder, causing the grinding wheel on the support rod to contact the edge of the aluminum ingot and perform the chamfering. In this solution, by changing the orientation of the support rod, grinding operations can be performed on the cut end face and periphery of the aluminum ingot, preventing wavy lines and chipping on the cut surface and periphery. Simultaneously, chamfering can be achieved, reducing subsequent processing steps.
[0009] Furthermore, the support rod includes a rod body hinged to the rotating seat, and the telescopic cylinder is connected to the rod body; an adjusting rod is slidably arranged coaxially at the end of the rod body, the frosted block is rotatably connected to the adjusting rod, and the drive motors are all arranged on the corresponding adjusting rods; an adjusting telescopic rod for driving the adjusting rod to slide is provided inside the rod body.
[0010] In this solution, during grinding operations, the adjusting rod can be moved back and forth by adjusting the telescopic rod, which in turn drives the grinding wheel to move back and forth. Combined with the adjusting cylinder and power-driven linear movement of the grinding wheel, this achieves a complex movement. The grinding wheel's movement trajectory becomes a crisscrossing network, more comprehensively covering the workpiece surface and eliminating grinding blind spots inherent in unidirectional movement. Furthermore, this complex motion produces finer, more varied surface textures, reducing obvious directional lines, making it particularly suitable for applications requiring high surface finish. Simultaneously, the cut surfaces of recycled aluminum ingots are prone to micro-dimples or protrusions. Prolonged contact of the grinding wheel in the same position can lead to localized over-grinding. The complex movement dynamically changes the contact position between the grinding wheel and the aluminum ingot, dispersing grinding pressure and reducing the risk of localized wear or ablation.
[0011] Furthermore, the grinding wheel includes two coaxial and adjacent grinding wheel bodies. Each grinding wheel body has a coaxially fixed annular support on its inner wall, and each support end has a coaxially formed annular groove. The supports are rotatably connected to an adjusting rod. The drive motor is parallel to the adjusting rod, and each drive motor end has a coaxially fixed support shaft. A drive gear coaxially fixed to the support shaft meshes with the side wall of one of the grooves. A driving gear and a driven gear are coaxially rotatably connected to the support shaft. The driving gear meshes with the side wall of the other groove. A reversing gear meshes between the driven gear and the corresponding groove side wall. A bracket is provided on the adjusting rod, and the reversing gear is rotatably connected to the bracket. Two grooves are formed on the support shaft, and each groove contains a limiting telescopic rod. Limiting holes that mate with the corresponding limiting telescopic rods are provided on the inner walls of both the driving and driven gears.
[0012] In this design, the limiting telescopic rod corresponding to the driving gear extends into the limiting hole of the driving gear, while the other limiting telescopic rod is submerged in the groove. At this time, the drive motor drives the support shaft to rotate the driving gear and the driving gear synchronously, thereby driving the two supports on the same support rod to rotate synchronously in the same direction, thus enabling the two grinding wheels to rotate synchronously in the same direction for operation. In addition, the limiting telescopic rod corresponding to the driven gear extends into the limiting hole of the driven gear, while the other limiting telescopic rod is submerged in the groove. When the drive motor drives the support shaft to rotate, the support shaft drives the driving gear and the driven gear to rotate. The driven gear then drives the corresponding support to rotate through the meshing reversing gear. At this time, the two supports on the same support rod rotate synchronously in opposite directions, thereby driving the two adjacent grinding wheels to rotate synchronously in opposite directions for grinding operations.
[0013] Two grinding wheels can simultaneously act on the same longitudinal area of an aluminum ingot (such as a straight line or a narrow surface). The counter-rotating cutting force removes aluminum chips from both directions. Compared to a single grinding wheel or an off-axis dual grinding wheel, a single movement can achieve twice the cutting amount, making it particularly suitable for efficient grinding of narrow and long areas such as the sides and welds of aluminum profiles. Furthermore, the coaxial counter-rotation can offset the radial runout error of the grinding wheels themselves, while bi-directional cutting avoids the "single-sided burrs" caused by grinding in one direction, resulting in a finer and more uniform cutting texture on the aluminum surface. This reduces the workload of subsequent fine grinding or polishing by approximately 30%. Additionally, the horizontal cutting forces generated by the counter-rotation cancel each other out, retaining only the vertical grinding pressure. This effectively prevents the workpiece from shifting due to unilateral force during synchronous movement, providing better protection for the dimensional accuracy of easily deformable workpieces such as thin-walled aluminum tubes and strips.
[0014] Furthermore, each of the adjusting rods is equipped with a spraying device for spraying lubricant between adjacent grinding wheels.
[0015] Furthermore, the conveying structure includes an annular support base, a pressing cylinder is provided at the top of the support base, a pressing plate is provided at the end of the pressing cylinder, support rods are hinged to both sides of the inner wall of the support base, a swing telescopic rod is hinged between the support rod and the support base, and a roller for driving aluminum ingots is provided at the end of the support rod.
[0016] Furthermore, the support has rounded corners on the periphery facing the drive motor end.
[0017] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0024] like Figures 1-4 As shown:
[0025] A cutting device for producing recycled aluminum ingots 28 includes a workbench 1 with an installation groove. A cutting device and a grinding device are respectively installed at both ends of the installation groove. The cutting device includes a swing arm 2 hinged to the workbench 1, with a torsion spring at the hinge point (a conventional technique, therefore not shown in the figure). A cutting tool 3 is installed at the end of the swing arm 2 (the swing arm 2 and the cutting tool 3 are conventional techniques, therefore not described in detail). The grinding device includes a power cylinder 4 perpendicular to the conveying direction of the aluminum ingots 28. A support frame 5 is installed at the output end of the power cylinder 4, and grinding structures are installed on both sides of the support frame 5. Two conveying structures for conveying aluminum ingots 28 are symmetrically arranged on the workbench 1 about the installation groove.
[0026] In this scheme, aluminum ingots 28 are conveyed and temporarily fixed by conveying structures at both ends, and the aluminum ingots 28 are cut and placed in the installation groove. Then, the swing arm 2 is used to cut the aluminum ingots 28 by the cutter 3 at the end of the swing arm 2. The aluminum ingots 28 are then moved forward by the conveying structure corresponding to the cut aluminum ingots 28, so that there is a gap between the aluminum ingots 28 at both ends. At this time, the support frame 5 is driven by the power cylinder 4, and the grinding structure on the support frame 5 is used to grind the cut end faces of the aluminum ingots 28 on both sides, so that the cut surface of the recycled aluminum ingots 28 is smoother and flatter, which is conducive to subsequent processing. After grinding, the cut aluminum ingots 28 are conveyed away by two conveying structures, and the aluminum ingots 28 to be cut are moved to the cutting position facing the installation groove.
[0027] Furthermore, the polishing structure includes an adjusting cylinder 6 vertically mounted on a support frame 5, a base 7 vertically slidably connected to the support frame 5 at the output end of the adjusting cylinder 6, a rotating seat 8 horizontally perpendicular to the support frame 5 rotatably mounted on the base 7, and a rotary motor for driving the rotating seat 8 to rotate on the base 7; a vertically mounted support rod is hinged to the rotating seat 8, and a torsion motor for pushing the support rod to deflect is mounted on the rotating seat 8; an annular abrasive block is coaxially rotatably connected to each support rod, and a drive motor 11 for driving the abrasive wheel to rotate is mounted on each support rod.
[0028] In this scheme, when the cut surface needs to be polished, the support rod is driven to swing vertically by a torsion motor, and the aluminum ingot 28 is moved by a conveying structure so that the end face of the aluminum ingot 28 can contact the grinding wheel on the support rod. At this time, the grinding wheel is driven by the power cylinder 4 and the support frame 5 to polish the cut end face of the aluminum ingot 28. When the peripheral side of the end of the aluminum ingot 28 needs to be polished, the support rod is driven to swing horizontally by a torsion motor, and the base 7 is driven to slide by the adjusting cylinder 6, so that the grinding wheel on the end face of the support rod contacts the horizontal surface of the end of the aluminum ingot 28. At this time, the grinding wheel is driven by the power cylinder 4 and the support frame 5 to polish the horizontal surface of the peripheral side of the aluminum ingot 28. Then, the grinding wheel is driven by the power cylinder 4 and the support frame 5 to move to contact the vertical surface of the peripheral side of the aluminum ingot 28. At this time, the grinding wheel is driven to move vertically by the adjusting cylinder 6, so as to polish the vertical surface of the peripheral side of the aluminum ingot 28. Furthermore, when the end face of aluminum ingot 28 requires chamfering, a torsion motor is used to deflect the support rod to an inclined position. The position of the support rod is adjusted by the power cylinder 4 and the adjusting cylinder 6, so that the grinding wheel on the support rod contacts the edge of the end of aluminum ingot 28 for chamfering. In this solution, by changing the orientation of the support rod, the cut end face and the periphery of aluminum ingot 28 can be ground to prevent wavy lines and chipping from appearing on the cut surface and periphery of aluminum ingot 28; at the same time, chamfering can be achieved, reducing the number of subsequent processing steps.
[0029] Furthermore, the support rod includes a rod body 9 hinged to the rotating seat 8, and the telescopic cylinder is connected to the rod body 9; an adjusting rod 12 is slidably arranged coaxially at the end of the rod body 9, the abrasive block is rotatably connected to the adjusting rod 12, and the drive motors 11 are all arranged on the corresponding adjusting rods 12; an adjusting telescopic rod 10 (an electric telescopic rod is used in this embodiment) is provided inside the rod body 9 for driving the adjusting rod 12 to slide.
[0030] In this design, during grinding operations, the adjusting rod 12 can be moved back and forth by adjusting the telescopic rod 10, which in turn drives the grinding wheel to move back and forth. Combined with the adjusting cylinder 6 and the power-driven linear movement of the grinding wheel, this results in a composite movement of the grinding wheel. This transforms the grinding wheel's movement trajectory into a crisscrossing network, allowing for more comprehensive coverage of the workpiece surface and eliminating grinding blind spots inherent in unidirectional movement. Furthermore, this composite motion produces finer, more varied surface textures, reducing noticeable directional lines, making it particularly suitable for applications requiring high surface finish. Simultaneously, the cut surfaces of recycled aluminum ingots 28 are prone to micro-dents or protrusions. Prolonged contact of the grinding wheel at the same position can lead to localized over-grinding. The composite movement dynamically changes the contact position between the grinding wheel and the aluminum ingot 28, dispersing the grinding pressure and reducing the risk of localized wear or ablation.
[0031] Furthermore, the abrasive wheel includes two coaxial and adjacent abrasive wheel bodies 13. Each abrasive wheel body 13 has an annular support coaxially fixed to its inner wall, and each support has an annular groove coaxially formed at its end. The supports are rotatably connected to the adjusting rod 12. The drive motor 11 is parallel to the adjusting rod 12. Each drive motor 11 has a support shaft 15 coaxially fixed to its end. A drive gear 16 coaxially fixed to the support shaft 15, meshing with the sidewall of one of the grooves, is also coaxially rotatably connected to the support shaft 15. The gear 18 has a drive gear 17 that meshes with the side wall of another groove; the driven gear 18 has a reversing gear 20 meshing with the side wall of the corresponding groove; the adjusting rod 12 has a bracket 21, and the reversing gear 20 is rotatably connected to the bracket 21; the support shaft 15 has two grooves, and each groove is provided with a limiting telescopic rod 19 (an electric telescopic rod is used in this embodiment); the inner walls of the drive gear 17 and the driven gear 18 are provided with limiting holes that cooperate with the corresponding limiting telescopic rod 19.
[0032] In this scheme, the limiting telescopic rod 19 corresponding to the control drive gear 17 extends into the limiting hole of the drive gear 17, while the other limiting telescopic rod 19 is submerged in the groove. At this time, the drive motor 11 drives the support shaft 15 to drive the drive gear 17 and drive gear 16 to rotate synchronously, thereby driving the two supports on the same support rod to rotate synchronously in the same direction, thus enabling the two grinding wheels 13 to rotate synchronously in the same direction for operation. In addition, the limiting telescopic rod 19 corresponding to the control driven gear 18 extends into the limiting hole of the driven gear 18, while the other limiting telescopic rod 19 is submerged in the groove. When the drive motor 11 drives the support shaft 15 to rotate, the support shaft 15 drives the drive gear 16 and driven gear 18 to rotate. The driven gear 18 then drives the corresponding support to rotate through the meshing reversing gear 20. At this time, the two supports on the same support rod rotate synchronously in opposite directions, thereby driving the two adjacent grinding wheels 13 to rotate synchronously in opposite directions for grinding operations.
[0033] Two grinding wheels 13 can simultaneously act on the same longitudinal area (such as a straight line or a narrow surface) of the aluminum ingot 28. The counter-rotating cutting force can remove aluminum chips from two directions. Compared with a single grinding wheel 13 or an off-axis double grinding wheel 13, a single movement can achieve twice the cutting amount, which is especially suitable for efficient grinding of narrow and long areas such as the sides and welds of aluminum profiles. In addition, the coaxial counter-rotation can offset the "radial runout" error of the grinding wheel 13 itself. At the same time, bi-directional cutting can avoid "single-sided burrs" caused by grinding in one direction, making the cutting texture on the surface of the aluminum part more delicate and uniform. The amount of subsequent fine grinding or polishing work can be reduced by about 30%. Meanwhile, the horizontal cutting forces generated by the counter-rotation cancel each other out, leaving only the grinding pressure in the vertical direction. This can effectively prevent the workpiece from shifting due to unilateral force during synchronous movement, and provides better protection for the dimensional accuracy of easily deformable workpieces such as thin-walled aluminum tubes and aluminum strips.
[0034] Furthermore, each of the adjusting rods 12 is equipped with a spraying device for spraying lubricant between adjacent grinding wheel bodies 13.
[0035] In this solution, lubricant is sprayed onto the grinding wheel bodies 13 through a spraying device to reduce wear between adjacent grinding wheel bodies 13.
[0036] Furthermore, the conveying structure includes an annular support base 22, a pressing cylinder 23 is provided at the top of the support base 22, a pressing plate 24 is provided at the end of the pressing cylinder 23, support rods 25 are hinged to both sides of the inner wall of the support base 22, and a swing telescopic rod 26 (an electric telescopic rod is used in this embodiment) is hinged between the support rod 25 and the support base 22, and a roller 27 for driving the aluminum ingot 28 is provided at the end of the support rod 25.
[0037] When cutting and grinding, the clamping cylinder 23 is controlled to push the clamping plate 24 to fasten the aluminum ingot 28. When it is necessary to move the aluminum ingot 28, the swing telescopic rod 26 is controlled to extend, so that the support rod 25 swings to the end of the roller 27 to contact the side wall of the aluminum ingot 28. The roller 27 is driven to rotate by an external motor, and the friction between the roller 27 and the aluminum ingot 28 is used to move the aluminum ingot 28.
[0038] Furthermore, the support has rounded corners on the periphery of the end facing the drive motor 11.
[0039] The support end is rounded to reduce the supporting force of the support end on the grinding wheel body 13, reduce the grinding effect of adjacent ends of the grinding wheel body 13, and prevent excessive grinding of aluminum ingot 28 at the contact point of adjacent grinding wheel bodies 13.
[0040] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
