10. A one-time stamping forming method based on aluminum alloy door and window processing, comprising a one-time stamping forming die applied to the aluminum alloy door and window processing as described in claim 9, characterized in that, Includes the following steps: S1: Before stamping, the extension rod of the hydraulic push rod (19) is retracted to its shortest state. At this time, the sliding hinge seats (9) at both ends of the U-shaped tie rod (18) and the side pressure blocks (12) rise to the top position. Under the tension of the reset spring (17), the tops of the two side pressure blocks (12) are open and away from the middle forming platform (601). S2: Then place the profile blank (13) to be stamped in the middle of the upper surface of the forming platform (601), then face the opening of the C-shaped clamp (141) toward the middle of the mold boss (6), and push the grooved slide frame (143) into the side slide groove (7) as a whole, and then pull the two rubber pressure rollers (142) upward until the rubber pressure rollers (142) are pressed on the upper surface end of the profile blank (13) at the top of the forming platform (601); S3: Control the extension rod of the hydraulic push rod (19) to extend and start bending. At this time, the side pressure blocks (12) on both sides will slowly descend. Under the contact of the extrusion roller frame (3) and extrusion roller (4) on both sides, the two open side pressure blocks (12) will come together until the vertical plate and horizontal plate of the side pressure block (12) are in a horizontal and vertical state respectively. If it continues to descend, the bending of the two wings of the profile blank (13) will be completed. Then, control the geared motor (152) to start, which will drive all the impact columns to continuously strike the crease after bending.
