[0004] When the device is actually used, it is difficult to ensure that the head and tail ends of the aluminum profile are on the same horizontal line during the pushing process of the aluminum profile. In addition, the device lacks an integrated structure that can automatically correct the position of the aluminum profile, which makes the aluminum profile prone to deflection and affects the straightening effect. For this reason, we provide an aluminum profile straightening device. Utility Model Content

[0031] An automatic position correction component includes two groups of connecting plates 101 symmetrically and movably connected to the top of the straightening table 1, a limit frame 102 is arranged on one side of the connecting plate 101, a guide roller 103 is equidistantly and rotatably connected to the limit frame 102, a connecting rod 104 is hinged between the connecting plate 101 and the connecting seat through a hinge, a limit slider is symmetrically and fixedly connected to the bottom of the connecting plate 101, a limit slot is arranged at the top of the straightening table 1 corresponding to the position of the limit slider and is slidably connected to the limit slider, which can guide the horizontal movement of the connecting plate 101;

[0032] The automatic position correction component also includes:

[0033] Two groups of cross bars 105 are symmetrically fixedly connected to one side of the connecting plate 101. The outside of the cross bar 105 is symmetrically slidably connected with a moving block. The moving block and the limit frame 102 are hinged with a connecting rod three 106. The outside of the cross bar 105 is symmetrically sleeved with a spring one 107.

[0034] The anti-warping component includes a sliding rod 201 which is laterally fixedly connected above the straightening table 1, a slider 202 is symmetrically slidably connected to the outside of the sliding rod 201, and the slider 202 is fixedly connected to the connecting plate 101 on the same side, a horizontal plate 203 is arranged below the sliding rod 201, a lower pressure frame 204 is arranged below the horizontal plate 203, a pressure roller 205 is symmetrically rotatably connected to the bottom of the lower pressure frame 204, and a connecting rod 206 is hinged between the horizontal plate 203 and the slider 202 through a hinge.

[0035] The anti-lift component also includes:

[0036] Two groups of vertical rods 207 are symmetrically fixedly connected to the top of the lower pressing frame 204 and slidably connected to the horizontal plate 203. The outer part of the vertical rods 207 is provided with a second spring 208.

[0037] The implementation principle of an aluminum profile straightening device in the embodiment of the present application is as follows: first, the aluminum profile is placed on the straightening table 1 and one end of it is on the top of the lower straightening roller 4, and then the hydraulic cylinder 2 is started. In the process of pushing the upper straightening roller 3 vertically downward by the hydraulic cylinder 2, the hinged effect between the connecting seat and the connecting plate 101 and the connecting rod 104 is utilized, and the sliding cooperation between the limiting slide groove and the limiting slide block can drive the two groups of connecting plates 101 to move inward at the same time, thereby driving the two groups of limiting frames 102 to move toward each other to push the aluminum profile toward the center, thereby ensuring that the head and tail ends of the aluminum profile can always be kept on the same horizontal line during straightening. When the guide roller 103 first contacts the aluminum profile, the sliding cooperation between the moving block and the cross bar 105, the hinged effect of the moving block and the connecting plate 101 and the connecting rod three 106, can make it possible to push the moving block to slide to both sides of the cross bar 105 and compress the spring 107, thereby playing a certain buffering role until the upper straightening roller 3 contacts the aluminum profile. When the aluminum profile is pushed toward the center, the movement of the connecting plate 101 will also drive the slider 202 to slide on the slide bar 201. The slider 202 and the hinged connection between the horizontal plate 203 and the connecting rod 206 can push the horizontal plate 203 downward, thereby driving the lower pressing frame 204 downward to press the top of the aluminum profile downward to limit the position, effectively preventing the aluminum profile from tilting at one end when the other end is squeezed and straightened. After contact, the sliding cooperation between the horizontal plate 203 and the vertical rod 207 is used to make the lower pressure frame 204 squeeze the spring 208, thereby playing a certain buffering role until the upper straightening roller 3 contacts the aluminum profile, and then the motor is started to drive the upper straightening roller 3 and the lower straightening roller 4 to rotate inward at the same time, and then the aluminum profile is pushed, and the rotation of the guide roller 103 and the pressure roller 205 is used to smoothly push the aluminum profile, and finally the straightened aluminum profile can be pulled out from the other end.

[0038] Embodiment 2:

[0039] This embodiment is further improved on the basis of the embodiment 1 in that the top of the vertical rod 207 is fixedly connected to a limiting plate, which can prevent the vertical rod 207 from being separated from the horizontal plate 203 .

[0040] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
