[0002] Aluminum-based composites have shown great application potential in aerospace, transportation, electronic packaging and other fields due to their excellent specific strength, specific modulus, good thermal conductivity and wear resistance, especially particle or fiber reinforced aluminum-based composites. By adding reinforcing phases such as ceramic particles and carbon fibers to the aluminum matrix, the mechanical properties, thermophysical properties and tribological properties of the material are significantly improved.

[0003] However, during the processing, residual stress will be generated inside the plate, causing deformation, cracking and other problems, affecting the product precision and service life. Traditional leveling equipment only focuses on geometric shape correction and is difficult to eliminate residual stress. In addition, there are designs such as being unable to adapt to different plate thicknesses and lacking surface cleaning functions, which may cause impurities to scratch the plate or induce new stress concentration. Based on this, a comprehensive leveling device for aluminum-based composite plates with integrated residual stress elimination is proposed for improvement. Summary of the Invention

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0020] Reference Figure 1-8 , which is the first embodiment of the present invention, provides an integrated leveling device for aluminum-based composite plates with integrated residual stress elimination, including a workbench 1, a leveling box 2 fixedly connected to the top of the workbench 1, a plurality of heating tubes 21 provided inside the leveling box 2, a plurality of pressing rollers 75 provided inside the leveling box 2, a plurality of conveying rollers 41 rotatably connected to the inner wall of the top of the workbench 1, the plurality of pressing rollers 75 being arranged above the plurality of conveying rollers 41, and an aluminum plate body 6 being provided between the pressing rollers 75 and the conveying rollers 41; The workbench 1 includes a striking mechanism 5 for striking the plate. A transmission shaft 51 is fixedly sleeved on one end of a conveying roller 41 at the center of the inner wall at the top of the workbench 1. The transmission shaft 51 is rotatably connected to a rotating shaft 53 through a second sprocket assembly 52. ​​The rotating shaft 53 is rotatably connected to the inner wall of the bottom of the workbench 1. Two cams 54 are fixedly sleeved on the outer surface of the rotating shaft 53. A connecting plate 55 is provided below the cam 54. The bottom surface of the cam 54 contacts the top of the connecting plate 55. Both ends of the top of the connecting plate 55 are fixedly connected to fixed columns 56. The top of the fixed column 56 is fixedly connected to a lifting rod 57. The top of the lifting rod 57 passes through the inner wall partition of the workbench 1 and contacts the bottom end of the aluminum plate body 6. A spring 58 is sleeved on the surface of the lifting rod 57, and the two ends of the spring 58 are respectively connected to the top of the fixed column 56 and the bottom end of the inner wall partition of the workbench 1; The workbench 1 also includes a conveying mechanism 4, and a plurality of conveying rollers 41 are fixedly sleeved with a linkage shaft 42 at one end. Two adjacent linkage shafts 42 are connected by a first sprocket assembly 43. A protective shell 44 is sleeved on the outside of the linkage shaft 42. The protective shell 44 is fixedly connected to one side of the workbench 1. A first motor 45 is fixedly installed on one side of the middle of the protective shell 44. The output shaft of the first motor 45 is sleeved with the linkage shaft 42 at the center of the inner wall of the protective shell 44.

[0021] During use, the first motor 45 is first started, and its output shaft drives the linkage shaft 42 in the protective shell 44 to rotate, which drives the adjacent linkage shafts 42 to rotate synchronously through the first sprocket assembly 43, thereby causing all the conveying rollers 41 to rotate synchronously, and the aluminum plate body 6 is fed into the device from the inlet; The aluminum plate body 6 moves forward along with the conveying roller 41 and enters the rolling zone between the pressing roller 75 and the conveying roller 41. The pressing roller 75 applies vertical pressure to the aluminum plate body 6, causing it to undergo plastic deformation, preliminarily eliminating surface warping or wavy defects. Then, the heating tube 21 is energized to generate heat, uniformly heating the aluminum plate body 6 entering the box, reducing the residual stress and hardness inside the aluminum plate body 6 and improving its plastic deformation capability. When the conveying roller 41 at the top center of the workbench 1 rotates, it drives the transmission shaft 51 to rotate synchronously. The transmission shaft 51 drives the rotating shaft 53 to rotate through the second sprocket assembly 52, and the cam 54 on the rotating shaft 53 rotates accordingly. When the cam 54 rotates, its bottom surface periodically squeezes the connecting plate 55, causing the fixed column 56 to drive the lifting rod 57 to move downward. When the raised part of the cam 54 rotates away, the spring 58 resets the lifting rod 57, and the top end of the lifting rod 57 knocks the bottom end of the aluminum plate body 6, completing a knocking cycle, and releasing the residual stress inside the aluminum plate body 6 through mechanical vibration; This design first reduces the stress hardness of the aluminum plate body 6 through the heating tube 21, and the pressure roller 75 and the conveying roller 41 achieve geometric leveling. Then, through the cooperation of the conveying mechanism 4 and the knocking mechanism 5, the aluminum plate body 6 can be periodically knocked to further release the residual stress inside the plate, avoid deformation caused by stress redistribution after rolling, and ensure the flatness of the aluminum plate body 6 and the uniformity of internal stress.

[0022] Reference Figure 1-8 , which is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: an adjustment mechanism 7 is provided inside the leveling box 2, a second motor 71 is fixedly installed at the center of the top of the leveling box 2, a threaded column 72 is fixedly sleeved on the output shaft of the second motor 71, and the threaded column 72 is rotatably connected to the inside of the leveling box 2, a threaded sleeve 73 is threadedly connected to the surface of the threaded column 72, and a lifting frame 74 is fixedly connected to the bottom end of the threaded sleeve 73. A plurality of pressure rollers 75 are rotatably connected to the bottom of the lifting frame 74, and guide columns 76 are symmetrically provided on the top of the lifting frame 74. The guide columns 76 are slidably connected to the inside of the top of the leveling box 2; A cavity 8 is defined inside each of the pressure rollers 75 . Ball baffles 81 are symmetrically provided on the inner wall of the cavity 8 . A plurality of iron balls 82 are provided inside the cavity 8 .

[0023] During use, the second motor 71 is started, and its output shaft drives the threaded column 72 to rotate, and the external thread on the surface of the threaded column 72 engages with the internal thread of the threaded sleeve 73, so that the threaded sleeve 73 moves up and down along the axial direction of the threaded column 72; The threaded sleeve 73 drives the lifting frame 74 to rise and fall synchronously, thereby adjusting the gap between the pressure roller 75 and the conveying roller 41, so as to adapt to the different thicknesses of the aluminum plate body 6, ensuring that the rolling pressure is adapted to the thickness of the aluminum plate body 6. The guide column 76 can prevent the lifting frame 74 from deflecting during the lifting process, ensuring that the pressure roller 75 presses down vertically, avoiding uneven rolling of the plate due to tilting; When the pressure roller 75 rotates, the iron ball 82 in the internal cavity 8 hits the inner wall of the cavity 8 from the ball baffle 81 under the action of gravity, thereby generating vibration. The vibration is transmitted to the aluminum plate body 6 through the surface of the pressure roller 75, forming a two-way impact up and down with the knocking vibration of the knocking mechanism 5, further decomposing the residual stress concentration area inside the aluminum plate body 6, targeting the micro-stress generated by local plastic deformation during the rolling process.

[0024] Reference Figure 1-8 , which is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a cleaning mechanism 3 is provided on the top of the workbench 1, and a mounting bracket 31 is provided on one side of the feed port of the leveling box 2, and the mounting bracket 31 is fixedly connected to the top of the workbench 1; A dust exhaust pipe 32 is provided on one side of the mounting frame 31, and two dust suction pipes 33 are fixedly sleeved on one side of the dust exhaust pipe 32. The upper dust suction pipe 33 on one side of the dust exhaust pipe 32 is fixedly installed on the inner wall of the mounting frame 31, and the lower dust suction pipe 33 on one side of the dust exhaust pipe 32 is fixedly installed on the inner wall of the top of the workbench 1; A brush 34 is fixedly connected to one side of the dust suction pipe 33 , a plurality of dust suction holes 35 are opened on one side of the dust suction pipe 33 , the interior of the dust exhaust pipe 32 is connected to the interior of the dust suction pipe 33 , and a fan 36 is fixedly installed on the other side of the dust exhaust pipe 32 .

[0025] During use, before the aluminum plate body 6 enters the leveling box 2, it first passes through the channel between the upper and lower sets of brushes 34, and its elastic bristles come into contact with the surface of the plate to brush away dust and other attached impurities; After the fan 36 is started, negative pressure is generated and transmitted to the inside of the dust collection pipe 33 through the dust discharge pipe 32. The multiple dust collection holes 35 on the dust collection pipe 33 form a local vacuum area, sucking the impurities picked up by the brush 34 and the dust on the surface of the aluminum plate body 6 into the pipe. The impurities sucked into the dust collection pipe 33 are collected into the dust discharge pipe 32 through the internal channel and discharged from the outlet of the fan 36 to an external dust collection box (not shown), thereby preventing the accumulation of impurities in the device or secondary contamination of the plate. This design cooperates with the cleaning mechanism 3 and the conveying mechanism 4. When the first motor 45 starts to convey the plate, the brush 34 brushes off the dust and other attached impurities on the surface of the aluminum plate body 6, and the fan 36 is turned on simultaneously to ensure that the surface of the aluminum plate body 6 is clean before entering the leveling box 2, avoiding impurities being carried into the rolling process, causing scratches on the surface of the aluminum plate body 6 or stress concentration to form defects.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
