Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy profile processing, in particular to a straightening device for aluminum alloy profile production. Background Art

[0002] In the production process of aluminum alloy profiles, straightening is a crucial link. Due to the uneven internal temperature distribution of aluminum alloy profiles during extrusion molding, uneven force is applied, which causes the extruded profiles to often have a certain degree of curvature. This curvature not only affects the appearance quality of the profile, but also causes inconvenience to its subsequent processing, installation and use. Therefore, the staff will use a straightening device to straighten the aluminum alloy profiles.

[0003] When straightening aluminum profiles, the straightening device usually pulls the two ends of the aluminum profile. However, for some profiles with large curvature or complex curvature shapes, the curvature cannot be completely eliminated during the stretching and straightening process.

DETAILED DESCRIPTION

[0030] 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.

[0031] Next, a specific embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0032] A straightening device for producing aluminum alloy profiles includes a fixed plate 1, and the upper surface of the fixed plate 1 is symmetrically fixedly connected to a straightening device 101, which is used to straighten the aluminum profile. The inner side of the straightening device 101 is provided with an upper clamp 102, which is used to clamp the aluminum profile when it moves up and down. The upper surface of the fixed plate 1 is provided with a transmission component 11, which is used to transport the aluminum profile.

[0033] As described in the background art, the straightening device usually pulls both ends of the aluminum profile when straightening it. However, for some profiles with large curvature or complex curvature shapes, the curvature cannot be completely eliminated during the stretching and straightening process.

[0034] In order to solve the problem that the aluminum profile with large bends cannot be corrected, this embodiment adopts the following technical solution: the two sides of the fixed plate 1 are symmetrically fixedly connected with fixing parts 16, the upper surface of the fixing part 16 on the rear side is fixedly connected with a first motor 12, the output shaft of the first motor 12 is fixedly connected with a screw rod 121, the first motor 12 is used to drive the screw rod 121 to rotate, the outer surface of the screw rod 121 is threadedly connected with a moving part 13, the screw rod 121 is used to drive the moving part 13 to move forward and backward, the outer surface of the front side of the first motor 12 is fixedly connected with a first guide rail 122, the The inner side of the upper surface of the moving part 13 is slidably connected to the outer surface of the first guide rail 122. The first guide rail 122 is used to guide the moving part 13 when it moves. The outer surface of the bottom of the moving part 13 is slidably connected to the connecting part 15. The moving part 13 is used to drive the connecting part 15 to move. A plurality of correction wheels 112 are provided at the bottom of the connecting part 15. The outer surfaces of the correction wheels 112 are used to ensure that the aluminum profile is evenly force applied during the correction process. The sides of the fixing parts 16 that are close to each other are inclined, and the lower surface of the connecting part 15 slides with the inclined surface of the fixing part 16.

[0035] The outer surfaces of both ends of the bottom of the moving member 13 are fixedly sleeved with a first spring 14, and the bottom ends of the first spring 14 are fixedly connected to the upper surface of the connecting member 15, and the first spring 14 is used to drive the connecting member 15 to squeeze downward, and the bottom of the connecting member 15 is symmetrically fixedly connected with a plurality of telescopic members 17, and the sides of the telescopic members 17 close to each other are fixedly connected with a second guide rail 110, and the outer surfaces of the second guide rail 110 are slidably connected with a plurality of sliding members 18, and the top of the correction wheel 112 is rotatably connected to the lower surface of the sliding member 18, and the sliding member 18 is used to drive the correction wheel 112 to move. The sides of the sliding members 18 close to each other are rotatably connected with a connecting rod 19, and the ends of the connecting rod 19 close to each other are rotatably connected to the outer surface of the bottom of the connecting member 15, and the outer surfaces of the second guide rail 110 are sleeved with a second spring 111, and the two ends of the second spring 111 are fixedly connected to the sides of the sliding members 18 close to each other, and the second guide rail 110 is used to support the sides of the sliding members 18 close to each other.

[0036] When the staff needs to straighten the aluminum profile, they can first place the aluminum profile on the left side of the upper surface of the transmission component 11. At this time, the transmission component 11 can drive the aluminum profile to move to the right. As the aluminum profile moves between the inner sides of the straightening device 101, the upper clamp 102 can clamp the two ends of the aluminum profile and straighten the aluminum profile through the straightening device 101. When the straightening device 101 is straightening, the output end of the first motor 12 can drive the screw rod 121 to rotate. When the screw rod 121 rotates, it will drive the moving part 13 to slide forward. When the moving part 13 slides forward on the outer surface of the first guide rail 122, it will drive the connecting part 15 to move at the same time, and the connecting part 15 is in the When the upper surface of the rear fixing member 16 moves forward, the lower surface of the connecting member 15 will be out of contact with the upper surface of the rear fixing member 16. At this time, the first spring 14 in a compressed state will drive the connecting member 15 to move downward. When the connecting member 15 moves downward, it will drive the second guide rail 110 to move at the same time through the telescopic member 17. When the second guide rail 110 moves downward, it will drive the correction wheel 112 to move at the same time through the sliding member 18. At this time, the correction wheel 112 can be located on both sides of the aluminum profile. Since the second spring 111 supports the side of the sliding member 18 that is close to each other, the sliding member 18 will not move inward when the sliding member 18 drives the correction wheel 112 to fit on the outer surface of the aluminum profile.

[0037] At this time, the first spring 14 can also drive the connecting member 15 to be squeezed downward. Since the outer surface of the bottom of the connecting member 15 is rotatably connected to the end of the connecting rod 19 that is close to each other, when the connecting member 15 moves downward, it can drive the end of the connecting rod 19 that is close to each other to move at the same time, and the end of the connecting rod 19 that is away from each other can pull the sliding member 18, causing the sliding member 18 to move toward the outer surface of the second guide rail 110 to move toward the side that is close to each other. During the movement, the sliding member 18 can squeeze the second spring 111 to a compressed state, and when the sliding member 18 moves, it can also drive the correction wheel 112 to move at the same time, causing the outer surface of the correction wheel 112 to fit the outer surface of the aluminum profile and slide forward, so that the aluminum profile is evenly applied with force during the straightening process, avoiding insufficient or excessive correction caused by excessive local force, and the correction wheel 112 can partially eliminate the residual stress inside the aluminum profile during the fitting process, thereby improving the stability and dimensional accuracy of the aluminum profile.

[0038] The bottom of the correction wheel 112 is rotatably connected to a ball 113, and the correction wheel 112 is used to drive the ball 113 to move. The upper surface of the fixed plate 1 is fixedly connected to a baffle 114, and the outer surface of the ball 113 slides with the upper surface of the baffle 114. As the sliding member 18 drives the correction wheel 112 to move downward, the correction wheel 112 can drive the ball 113 to move at the same time, so that the outer surface of the ball 113 can fit into the baffle 114. As the correction wheel 112 moves forward, it will drive the ball 113 to move simultaneously on the upper surface of the baffle 114, thereby reducing the friction generated when the correction wheel 112 slides, making the correction wheel 112 slide more smoothly.

[0039] As the aluminum profile is straightened, the output shaft of the first motor 12 can continue to drive the screw rod 121 to rotate, prompting the movable member 13 to then drive the connecting member 15 to move forward. When the connecting member 15 moves forward, the lower surface of the connecting member 15 can be in contact with the inclined surface of the front fixing member 16. At this time, when the connecting member 15 continues to move forward, it will prompt the connecting member 15 to gradually move upward, and when the connecting member 15 moves upward, the first spring 14 can be re-extruded into a compressed state, and when the connecting member 15 moves upward, the outer surface of the bottom of the connecting member 15 will drive the ends of the connecting rod 19 that are close to each other to move at the same time. At this time, the ends of the connecting rod 19 that are away from each other can drive the sliding member 18 to move toward the ends that are away from each other. As the sliding member 18 moves, it can not only drive the second spring 111 to return to its initial state, but also drive the correction wheel 112 to move at the same time, so that the outer surfaces of the correction wheel 112 can be separated from each other to clamp the aluminum alloy.

[0040] When the staff places the aluminum profile that needs to be straightened on the upper surface of the transmission assembly 11, the two ends of the aluminum profile will be uneven, resulting in the staff spending extra time to adjust the aluminum profile when straightening it, thereby reducing the adjustment efficiency of the aluminum profile.

[0041] In order to solve the problem of uneven aluminum profiles, this embodiment adopts the following technical solution: the upper surface of the fixed plate 1 is fixedly connected to the second motor 2, the output shaft of the second motor 2 is fixedly connected to the bidirectional screw 22, the second motor 2 is used to drive the bidirectional screw 22 to rotate, the outer surfaces of both ends of the bidirectional screw 22 are threadedly connected to the alignment parts 21, the bidirectional screw 22 is used to drive the alignment parts 21 to move back and forth, the rear side of the second motor 2 is fixedly connected to the third guide rail 23, the inner sides of the alignment parts 21 are slidably connected to the outer surface of the third guide rail 23, and the third guide rail 23 is used to limit the sliding position of the alignment parts 21.

[0042] As the staff places the aluminum profile on the upper surface of the transmission assembly 11 for transmission, the output end of the second motor 2 can drive the bidirectional screw 22 to rotate, and the rotation of the bidirectional screw 22 can drive the alignment member 21 to move back and forth, so that the side of the alignment member 21 that is close to each other can squeeze the two ends of the aluminum profile, so that the aluminum profile maintains a stable straight state during the straightening process, reducing bending or twisting caused by misalignment of the two ends.

[0043] The outer surface of the bidirectional screw 22 is linearly fixedly connected with a plurality of missing gears 24, and the bidirectional screw 22 is used to drive the missing gears 24 to rotate. The upper surface of the fixed plate 1 is fixedly connected with a plurality of limiting shafts 251, and the outer surface of the limiting shaft 251 is slidably connected with a shaking member 25. The upper surface of the right side of the shaking member 25 is extruded and matched with the bottom of the aluminum profile. The limiting shaft 251 is used to limit the sliding position of the shaking member 25. The outer surface of the missing gear 24 is meshed with the left end of the shaking member 25. The outer surface of the limiting shaft 251 is fixedly sleeved with a third spring 26, and the lower surface of the third spring 26 is fixedly connected to the upper surface of the shaking member 25.

[0044] As the output end of the second motor 2 drives the bidirectional screw 22 to rotate, the bidirectional screw 22 can drive the missing gear 24 to rotate at the same time. When the missing gear 24 rotates, the outer surface of the missing gear 24 can engage with the left end of the shaking member 25 and prompt the shaking member 25 to slide upward. When the shaking member 25 slides upward on the outer surface of the limit shaft 251, it will prompt the third spring 26 to move to a compressed state. When the shaking member 25 moves upward, the upper surface of the right end of the shaking member 25 can squeeze the bottom of the aluminum profile being straightened, so that the aluminum profile can produce a certain amount of plastic deformation. The plastic deformation can make the cross-sectional shape of the aluminum profile more regular and improve the straightening accuracy.

[0045] As the bidirectional screw 22 then drives the missing gear 24 to rotate, the outer surface of the missing gear 24 will disengage from the left end of the shaking member 25. At this time, the third spring 26 in a compressed state can drive the shaking member 25 to slide downward, so that the shaking member 25 returns to its initial state.

[0046] When the aluminum profile is placed on the upper surface of the transmission assembly 11 and moved, it is easy to cause collision and friction between the moving aluminum profile and the straightened aluminum profile, thereby affecting the straightening effect of the aluminum profile.

[0047] In order to solve the problem of mutual collision between aluminum profiles, this embodiment adopts the following technical solution: the left side of the upper clamp 102 is fixedly connected to the first rack 3, and the upper clamp 102 is used to drive the first rack 3 to move up and down. One side of the straightening device 101 is rotatably connected to a limiting member 33, and the limiting member 33 is used to block and flip the aluminum profile. The ends of the limiting members 33 away from each other are fixedly connected to the first gear 31, and the outer surface of the first gear 31 is engaged with the bottom of the left side of the first rack 3. The outer surfaces of the limiting members 33 away from each other are fixedly sleeved with a torsion spring 32, and the ends of the torsion springs 32 close to each other are fixedly connected to the outer surface of the straightening device 101, and the torsion spring 32 is used to drive the limiting member 33 to reset and rotate.

[0048] As the transmission assembly 11 transports the aluminum profile, the aluminum profile on the far right can fit against the left side of the limiting member 33. At this time, the upper clamp 102 can be gradually squeezed downward. When the upper clamp 102 is squeezed downward, it can drive the first rack 3 to be squeezed at the same time. When the first rack 3 is squeezed downward, it can drive the first gear 31 to rotate clockwise. When the first gear 31 rotates clockwise, it will drive the limiting member 33 to rotate at the same time. When the limiting member 33 rotates, it can rotate the torsion spring 32 to a stored force state, and can also drive the aluminum profile on the far right to flip to the right. When the limiting member 33 flips, it can also block other aluminum profiles, thereby preventing the aluminum profile to be processed from colliding with the aluminum profile being straightened. It can not only protect the outer surface of the aluminum profile, but also keep the straightening accuracy of the aluminum profile unaffected.

[0049] As the straightening device 101 drives the upper clamp 102 to move to both sides to straighten the aluminum profile, the upper clamp 102 can drive the first rack 3 to move at the same time. When the first rack 3 moves to both sides, the bottom of the left side of the first rack 3 can be disengaged from the outer surface of the first gear 31. At this time, the torsion spring 32 in the stored force state can drive the limiting part 33 and the first gear 31 to reset.

[0050] As the upper clamp 102 completes straightening of the aluminum profile, the upper clamp 102 can drive the first rack 3 to move upward, and the straightening device 101 can drive the upper clamp 102 to move toward the side close to each other. When the upper clamp 102 moves, it will drive the first rack 3 to move at the same time, so that the bottom left side of the first rack 3 can be re-engaged with the outer surface of the first gear 31.

[0051] The inner side of the straightening device 101 is fixedly connected to a fixed shaft 401, and the outer surface of the fixed shaft 401 is slidably connected to a wedge frame 4, and the inner side of the wedge frame 4 is rotatably connected to the second gear 41, and the wedge frame 4 is used to drive the second gear 41 to slide back and forth, and the bottom of the second gear 41 is meshed with a second rack 42, and the end of the second rack 42 away from each other is fixedly connected to the inner side of the straightening device 101, and the inner side of the straightening device 101 is fixedly connected to a guide shaft 43, and the outer surface of the guide shaft 43 is slidably connected to a third rack 44, and the outer surface of the top of the second gear 41 is meshed with the bottom of the third rack 44. The gear 41 is used to drive the third rack 44 to move forward and backward. The ends of the third racks 44 that are close to each other can be detachably connected with a filler 45. The filler 45 is used to fill the interior of the aluminum profile. The outer surface of the upper clamp 102 is fixedly connected with an extrusion piece 46. The upper clamp 102 is used to drive the extrusion piece 46 to move up and down. The outer surface of the wedge frame 4 is inclined, and the bottom of the extrusion piece 46 is squeezed and matched with the inclined surface of the outer surface of the wedge frame 4. The outer surface of the fixed shaft 401 is fixedly sleeved with a fourth spring 47. The left end of the fourth spring 47 is fixedly connected to the outer surface of the bottom of the wedge frame 4. The fourth spring 47 is used to drive the wedge frame 4 to slide again.

[0052] As the upper clamp 102 moves downward to extrude the aluminum profile, the upper clamp 102 can drive the extrusion piece 46 to move at the same time. When the extrusion piece 46 moves downward, it can squeeze the inclined surface of the wedge frame 4, causing the wedge frame 4 to slide to the right. When the wedge frame 4 slides to the right, it can squeeze the fourth spring 47 to a compressed state. When the wedge frame 4 slides, it can also drive the second gear 41 to move at the same time. As the second gear 41 moves to the right, the outer surface of the bottom of the second gear 41 can mesh with the upper surface of the second rack 42 and cause The second gear 41 rotates clockwise, and as the second gear 41 rotates, it can drive the third rack 44 to slide to the right on the outer surface of the guide shaft 43. When the third rack 44 slides to the right, it can drive the filler 45 to slide at the same time. At this time, the outer surface of the filler 45 can slide into the interior of the aluminum profile, which can provide the necessary supporting force for the aluminum profile during straightening, effectively preventing the aluminum profile from collapsing due to external force during the straightening process, and the filler 45 can also increase the rigidity of the aluminum profile, reducing the vibration and shaking of the aluminum profile during the straightening process.

[0053] As the aluminum profile is straightened, the upper clamp 102 can drive the extrusion piece 46 to move upward. At this time, the bottom of the extrusion piece 46 can be separated from the inclined surface of the wedge frame 4, and the fourth spring 47 in the compressed state can drive the second gear 41 to move left through the wedge frame 4. When the second gear 41 moves to the left, the second rack 42 can cause the second gear 41 to rotate counterclockwise. When the second gear 41 rotates counterclockwise, it will cause the third rack 44 to slide to the left on the outer surface of the guide shaft 43. As the third rack 44 slides to the left, it can drive the filler 45 to slide at the same time, so that the filler 45 can automatically slide out from the inside of the aluminum profile.
