The working principle is as follows:

when the device is needed, firstly, the device is connected with an external power supply, then a worker selects a corresponding inner correction module 15 and an outer correction module 14 according to the shape of an aluminum-plastic profile to be corrected, at the moment, the worker manually moves the outer correction module seat 10 to the position below the sliding platform 8, then lifts the outer correction module seat 10, enables the outer correction module seat 10 to be sleeved on the sliding platform 8, aligns the bolt hole 12 on the outer correction module seat 10 with the fixed bolt hole 9 on the sliding platform 8, at the moment, inserts the fixed bolt 13 into the bolt hole 12 and the fixed bolt hole 9, rotates the fixed bolt 13 through a tool, enables the fixed bolt 13 to be connected with the fixed nut 11, and accordingly, the outer correction module seat 10 is installed on the sliding platform 8, at the moment, the outer correction module 14 is installed, and at the same time, the worker places the inner correction module 15 in the rectangular correction box 1, and enables the inner correction module 15 to be located below the outer correction module 14;

at the moment, a worker places an aluminum-plastic door window to be corrected into the rectangular correction box 1 and is positioned on one side of the fixed top plate 2, then places a section of supporting aluminum-plastic door window with the same shape and size as the aluminum-plastic door window to be corrected between the fixed top plate 2 and the aluminum-plastic door window to be corrected, then uses a tool to enable two steel wire ropes 33 which are positioned on one side of the fixed top plate 2 and are connected with the internal correction module 15 to penetrate through the supporting aluminum-plastic door window and the aluminum-plastic door window to be corrected and extend out of the other end of the aluminum-plastic door window to be corrected, then the worker connects hooks 34 on the steel wire ropes 33 with hanging rings 18 of the internal correction module 15, and connects hooks 34 on the rest steel wire ropes 33 with hanging rings 18 of the other end of the internal correction module 15 and hanging rings 18 of two ends of the sliding platform 8 respectively;

at the moment, the operator manually pushes the aluminum-plastic section bar to be corrected to make the aluminum-plastic section bar to be corrected contact with the aluminum-plastic section bar for supporting, the aluminum-plastic section bar for supporting is contacted with the fixed top plate 2, at the moment, a worker controls the electric cylinder I4 to start working through the controller, so that the telescopic end of the electric cylinder I4 starts to extend out, thereby driving the concave sliding seat 5 to descend, and the descending of the concave sliding seat 5 drives the sliding platform 8 to descend, so that the outer correction module 14 begins to descend, the outer correction module 14 descends to the position corresponding to the shape of the aluminum-plastic section bar to be corrected, so that the outer straightening module 14 is inserted into the aluminum-plastic section bar to be straightened, and the controller controls the electric adjusting cylinder 29 to start working at the same time, due to the descending of the sliding platform 8, the steel wire rope 33 connected with the sliding platform 8 is in a loose state, and the outer pulley seat II 25 starts to descend through the extending position of the electric adjusting cylinder 29, thereby pulling the steel wire rope 33 to move downwards, keeping the steel wire rope 33 in a tight state, after the sliding platform 8 and the steel wire rope 33 are respectively adjusted, at the moment, the first electric cylinder 4 and the electric adjusting cylinder 29 are controlled to stop working, at the moment, the operator controls the second electric cylinder 19 to start working through the controller, along with the extension of the telescopic end of the second electric cylinder 19, the fixed baffle 20 starts to move and gradually approaches to the aluminum-plastic section bar to be corrected, when the fixed baffle 20 contacts with the aluminum-plastic section, the electric cylinder II 19 is controlled to stop working, the aluminum-plastic section is extruded, but the friction between the aluminum-plastic section bar and the rectangular correction box 1 and the fixed baffle 20 is lower, the aluminum-plastic section bar can move at the moment, and the aluminum-plastic section bar is fixed.
