[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] Example: See Figure 1 - Figure 7 An aluminum profile straightening device includes a base 1 and a turntable 2, which is arranged on the top of the base 1. The turntable 2 is a cross-shaped structure, and a plurality of structural grooves 3 are opened inside the turntable 2. The number of the structural grooves 3 is four.

[0042] The driving mechanism is arranged inside the base 1 and is used to drive the turntable 2 to rotate in sections. The driving mechanism includes a transmission shaft 4 installed on the inner wall of the bottom of the base 1 and a first motor 5 installed on the inner wall of the bottom of the base 1; the top of the transmission shaft 4 is fixedly connected to the bottom of the turntable 2; the outside of the output shaft of the first motor 5 and the outside of the transmission shaft 4 are fixedly sleeved with gears 6, and the two gears 6 are meshed;

[0043] The first motor 5 is controlled to drive the gear 6 outside its output shaft to rotate, and the transmission shaft 4 is driven to rotate through the meshing effect between the two gears 6, and then the turntable 2 is driven to rotate. The first motor 5 is controlled to drive the turntable 2 to pause after every quarter turn. The purpose of driving the turntable 2 to rotate is that the staff only needs to be at the position of one of the material ports 25 to realize the loading and unloading of aluminum profiles inside each structural groove 3.

[0044] A straightening mechanism is arranged inside the structural groove 3. There are also four straightening mechanisms, which are respectively located inside the four structural grooves 3 and are used to straighten the aluminum profiles. The straightening mechanism includes two straightening frames 7 arranged inside the structural groove 3 and two straightening plates 8 arranged inside the straightening frames 7. Two movable grooves are provided inside the straightening frames 7, and the straightening plates 8 are located inside the movable grooves to facilitate the movement of the straightening frames 7. One side of the straightening frames 7 is connected to a plurality of first hydraulic cylinders 9, which are installed inside the turntable 2. Slides 10 are fixedly connected to the outer walls of the opposite sides of the two straightening plates 8. Second hydraulic cylinders 11 are installed inside the two slides 10, and the extended ends of the two second hydraulic cylinders 11 are respectively fixedly connected to the outer walls of the opposite sides of the two straightening plates 8. First slide grooves 12 are provided on the top and bottom of the straightening frames 7, and the two slides 10 are respectively slidably connected inside the two first slide grooves 12.

[0045] The staff passes the aluminum profile through the two shaping blocks 16 and places it between the two straightening frames 7 and the two straightening plates 8. At this time, the aluminum profile is located on one side of the shaping block 16, so that when the two straightening frames 7 are close to each other, the shaping block 16 will not be stuck with the aluminum profile. After the aluminum profile is placed, the staff controls the extension of each second hydraulic cylinder 11 to drive the two straightening plates 8 arranged up and down to approach each other, clamp the aluminum profile, and straighten the top and bottom of the aluminum profile at the current position. Then, the staff extends each first hydraulic cylinder 9 to drive the two straightening frames 7 to approach each other, and straighten both sides of the aluminum profile.

[0046] Among them, when it is necessary to drive the correction plate 8 to move along the length direction of the aluminum profile, the second hydraulic cylinder 11 is first controlled to shorten, driving the two correction plates 8 to move away from each other. When the correction plate 8 moves, the slide 10 moves synchronously along the inside of the first slide groove 12, and the second hydraulic cylinder 11 also moves synchronously, changing the relative position of the correction plate 8 and the aluminum profile. Then, the second hydraulic cylinder 11 is controlled to extend, driving the two correction plates 8 to move closer to each other again, and straightening the top and bottom of the aluminum profile in the next area.

[0047] A shaping mechanism, which is connected to the straightening mechanism, and there are also four shaping mechanisms, which are used to shape the deformed positions inside the aluminum profile. The shaping mechanism includes a second slide groove 13 opened inside the straightening frame 7 and a screw rod 14 rotatably connected to the inside of the second slide groove 13; a slider 15 is screwed to the outside of the screw rod 14, and the slider 15 is slidably connected to the inside of the second slide groove 13. Shaping blocks 16 are fixedly connected to the outer walls of the opposite sides of the two sliders 15, and the outer walls of the shaping blocks 16 are adapted to the inner walls of the aluminum profile; one end of the straightening frame 7 extends to the outside of the turntable 2, and a second motor 17 is installed, and the straightening frame 7 is slidably connected to the inside of the turntable 2, and the output end of the second motor 17 is fixedly connected to one end of the screw rod 14;

[0048] When the two straightening frames 7 are close to each other, the two sides of the aluminum profile are straightened, and the two straightening plates 8 are close to each other, and the top and bottom of the aluminum profile at the current position are straightened, the aluminum profile in the inner area of ​​the two straightening plates 8 is heated by a fixed-point heating mechanism, and then the second motor 17 is controlled to drive the screw rod 14 to rotate, and then the slider 15 is driven to move along the inner wall of the second slide groove 13 toward the transmission shaft 4, and the shaping block 16 moves along the inner wall of the aluminum profile, so that the shaping block 16 moves to the end of the straightening plate 8. In this process, the shaping block 16 flattens the deformed position inside the aluminum profile.

[0049] The two correction plates 8 are connected to the slider 15 through a linkage assembly. The slider 15 is located between the two correction plates 8. The linkage assembly includes a plurality of telescopic rods 18 fixedly connected to the outer wall of the slider 15 and a plurality of third slide grooves 19 provided inside the correction plate 8; the extended end of the telescopic rod 18 is fixedly connected to a guide block 20, the guide block 20 is slidably connected inside the third slide groove 19, and a return spring 21 is provided inside the third slide groove 19, one end of the return spring 21 is fixedly connected to the outer wall of the guide block 20, and the other end of the return spring 21 is fixedly connected to the inner wall of the third slide groove 19; the straightening frame 7 is also provided with a plurality of through grooves 22 corresponding to the plurality of telescopic rods 18, and the telescopic rods 18 are located inside the through grooves 22;

[0050] When the slider 15 moves toward the transmission shaft 4, the correction plate 8 will not move because the correction plate 8 and the aluminum profile are in a relatively fixed state, and the slider 15 drives the guide block 20 to slide along the inner wall of the third slide groove 19 through the telescopic rod 18, and the return spring 21 is compressed accordingly. When the shaping block 16 moves to the end of the correction plate 8, that is, after the shaping of the current local aluminum profile is completed, the second hydraulic cylinder 11 is controlled to shorten, driving the two correction plates 8 to move away from each other, so that the correction plate 8 and the aluminum profile are aligned. The aluminum profile is out of contact with the material. At this time, the rebound force of the reset spring 21 drives the straightening plate 8, the slide 10 and the second hydraulic cylinder 11 to slide in the direction of the transmission shaft 4, and the guide block 20 is re-contacted with the inner wall of one side of the third slide groove 19, and then the second hydraulic cylinder 11 is controlled again to drive the two straightening plates 8 to straighten and heat the aluminum profile at the current position, and then continue to drive the slider 15 to move in the direction of the transmission shaft 4, and drive the shaping block 16 to shape the inside of the aluminum profile, and this cycle is repeated to shape the inside of the aluminum profile in sections.

[0051] The fixed-point heating mechanism is connected to the straightening mechanism and the shaping mechanism respectively, and is used to heat the local position of the aluminum profile. The fixed-point heating mechanism includes an auxiliary plate 23 fixed to the outer wall of the slider 15 and a plurality of heating tubes respectively installed inside the auxiliary plate 23 and the straightening plate 8; the auxiliary plate 23 is located inside the second slide groove 13, and an extension groove 24 corresponding to the auxiliary plate 23 is opened inside the turntable 2. When the slider 15 moves to the end of the straightening frame 7, the auxiliary plate 23 enters the extension groove 24;

[0052] When the two straightening frames 7 are close to each other and straightening treatment is performed on both sides of the aluminum profile, and the two straightening plates 8 are close to each other and straightening treatment is performed on the top and bottom of the aluminum profile at the current position, the auxiliary plate 23 and the heating tube inside the straightening plate 8 are controlled to perform synchronous heating treatment on all sides of the aluminum profile at the current position, so that when the shaping block 16 moves subsequently, the deformed position inside the aluminum profile can be more easily shaped, which effectively reduces the damage to the aluminum profile caused during the shaping process, and also solves the problem that the aluminum profile is easily clamped and deformed if the entire aluminum profile is heated at the same time.

[0053] A plurality of material ports 25 are provided on the outer wall of the turntable 2, and the plurality of material ports 25 are respectively connected to the plurality of structural grooves 3; a plurality of third hydraulic cylinders 26 are installed inside the turntable 2, and the plurality of third hydraulic cylinders 26 correspond to the plurality of material ports 25, respectively, and a pusher block is fixedly connected to the extended end of the third hydraulic cylinder 26;

[0054] The staff inserts the aluminum profile into the structural groove 3 through the material opening 25. After the external straightening and internal shaping of the aluminum profile are completed, one end of the aluminum profile is extended from the material opening 25 by controlling the extension of the third hydraulic cylinder 26, so that the staff can remove the processed aluminum profile.

[0055] Working principle: When in use, the staff passes the aluminum profile through the material port 25 between the two shaping blocks 16 and places it between the two straightening frames 7 and the two straightening plates 8. At this time, the aluminum profile is located on one side of the shaping block 16, so that when the two straightening frames 7 are close to each other, the shaping block 16 will not be stuck with the aluminum profile. After the aluminum profile is placed, the second hydraulic cylinders 11 are controlled to extend to drive the two upper and lower straightening plates 8 to approach each other, clamp the aluminum profile, and straighten the top and bottom of the aluminum profile at the current position. Then, the first hydraulic cylinders 9 are extended to drive the two straightening frames 7 to approach each other to straighten the aluminum profile. The two sides of the straightening treatment are carried out, the aluminum profiles in the inner area of ​​the two straightening plates 8 are heated by the fixed-point heating mechanism, and then the second motor 17 is controlled to drive the screw rod 14 to rotate, thereby driving the slider 15 to move along the inner wall of the second slide groove 13 toward the transmission shaft 4, and the shaping block 16 moves along the inner wall of the aluminum profile, so that the shaping block 16 moves to the end of the straightening plate 8. In this process, the shaping block 16 flattens the deformed position inside the aluminum profile. Among them, when the slider 15 moves toward the transmission shaft 4, the correction plate 8 and the aluminum profile are in a relatively fixed state, so the correction plate 8 will not move, and the slider 15 The block 15 drives the guide block 20 to slide along the inner wall of the third slide groove 19 through the telescopic rod 18, and the return spring 21 is compressed accordingly. When the shaping block 16 moves to the end of the correction plate 8, that is, after the shaping of the interior of the current local aluminum profile is completed, the second hydraulic cylinder 11 is controlled to shorten, driving the two correction plates 8 away from each other, so that the correction plates 8 are out of contact with the aluminum profile. At this time, the rebound force of the return spring 21 drives the correction plate 8, the slide 10 and the second hydraulic cylinder 11 to slide in the direction of the transmission shaft 4, and the guide block 20 is re-contacted with the inner wall of one side of the third slide groove 19, and then the second hydraulic cylinder is controlled again. After 11 drives the two straightening plates 8 to straighten and heat the aluminum profile at the current position, it continues to drive the slider 15 to move toward the transmission shaft 4, and drives the shaping block 16 to shape the inside of the aluminum profile, which effectively reduces the damage to the aluminum profile during the shaping process, and also solves the problem that the aluminum profile is easily deformed by clamping if the entire aluminum profile is heated at the same time. In this cycle, the inside of the aluminum profile is shaped in sections. After the straightening of the outside and the shaping of the inside of the aluminum profile are completed, one end of the aluminum profile is extended from the material port 25 by controlling the extension of the third hydraulic cylinder 26, so that the staff can remove the processed aluminum profile.
