The hat stringer stiffened panel forming apparatus of Claim 1, wherein The depth of the locking hole (507) is greater than the depth of the third clamping groove (506), and the depths of the first clamping groove (504), the second clamping groove (505) and the third clamping groove (506) are equal.

5. The hat stringer stiffened panel forming apparatus of Claim 1 wherein, The first L-shaped pull plate (11) and the second L-shaped pull plate (12) are symmetrically arranged along the transverse central axis of the T-shaped groove (10) when they are buckled into the inside of the T-shaped groove (10).

6. The hat-stringer stiffened panel forming apparatus of Claim 1, wherein The widths of the first clamping groove (504), the second clamping groove (505) and the third clamping groove (506) are equal, and the end face of the end face clamping block (6) is flush with the end face of the first connecting template (501) when it is buckled into the inside of the first clamping groove (504), the second clamping groove (505) and the third clamping groove (506).

7. A hat stringer-stiffened panel forming method characterized by comprising: The hat stringer stiffened wallboard forming device of any one of claims 1-6 comprises the following steps: S1: first prepare the core mold, prefabricated hat stringer and cut skin material; S2: precisely place the hat stringer (2) in the groove inside the supporting mold (1), then buckle the core mold (5) in the groove inside the hat stringer (2), so that it fits the inside contour of the hat stringer (2) as the internal support reference for subsequent forming; S3: lay the skin (3) on the top of the hat stringer (2) and the core mold (5), make sure to cover the flange and peripheral area of the hat stringer (2), and simply pre-press the skin (3) and the hat stringer (2) to preliminarily fit; S4: heat and press to cure, close the mold and apply pressure, and heat to the material curing temperature to make the whole body set; S5: after the temperature decreases, separate the core mold (5) from the formed wallboard through the splicing clamping piece, and the simple forming process of the hat stringer stiffened wallboard is completed.
