Abstract
PURPOSE: To manufacture curved surface pannel without attaching reinforcement member, by press processing the central part of one metal plate mirror face with convex and concave mating face having a fixed curved surface and at the same time carrying out bending processing of cicumference part.
CONSTITUTION: The die frame 8 having the plane shape similiar to the necessary mirror face, is set on the forming die 4 and the die 9 is composed by the above frame and die. Lower face of the punch 10 is made concave face with convex face of the die 4. Area of the punch 10 is larger than that of the necessary mirror face and the punch 10 is pressed down in the die 9 after the plane metal plate 1a having nearly the same shape to the mirror face, is arranged on the frame 8 of the die 9. Circumference part A of the plate 1a is bended at nearly 90° over the whole circumference and the other part B is made to two-dimensional curved face as mirror face. The above pannel is able to use for unit curved surface pannel of parabola reflex mirror face of antenna apparatus as it is. Also, when it is used for the above purpose, the curved surface pannel is accomplished by forming the pannel support hole 11 on the part A.
