DEFLECTION STRAIGHTENING METHOD OF BODY OUTER PLATE FOR AUTOMOBILE

PURPOSE:To straighten the shape deflection of said outer plate and to prevent the deflection re-generation of the straightened part by pressing a thermal hardening solid plastic plate via a thermosetting resin adhesive agent to the deflected part of a body outer plate for automobile after the formation and by performing a paint baking and straightening treatment of the deflected part with said condition. CONSTITUTION:The reinforcing member 1 having sufficient size to cover a deflected part C is applied in the inside of the chamber of the shape deflected part C of the automobile body B of the state of feeding to the next stage after the press formation. This member 1 forms the adhesive layer 3 by a thermosetting hardening adhesive agent on the side face of a thermosetting resin plate 2, and the protective film 4 consisting of a synthetic resin film is coated on the other face of the plate 2. An extrusion member 5 is then applied on the film 4, the outer force is loaded on the outdoor side by an adequate extruding means and with said state the body B is transferred to a painting stage T. Then after adhering TA a paint on the outer face of the body B, it is fed to a baking part TB and the adhered paint is baked. With this baking treatment the outer plate of the body B is softened, the deflected part C is extended, also the layer 3 of the member 1 is adhered with thermal hardening, and the deflected part C is straightened with holding the state of extending the part C.
