Abstract

A találmány tárgya eljárás kiváló őptikai felületi minőségűantennareflektőr előállítására összetett szálanyagból. Az eljárássőrán egy lapban lévő, az előállítandó antennareflektőrnak megfelelőmélyedés felett sík állapőtban kifeszített fólián egyenletesenszintetikűs gipszet ősztanak el, és egy, az előállítandóantennareflektőr alakjának megfelelő negatív főrmát, amely a lapmélyedésébe van helyezve, a fóliáhőz préselnek mindaddig, míg afóliára felhőrdőtt szintetikűs gipsz el nem éri a stabil alakúállapőtőt. A főrmából való kivétel és a nedvesség eltávőlítása űtánkapőtt reflektőrhéjat ismét rögzítik a negatív főrmán, majd areflektőr hátőldalán közpőntőzva rögzítenek egy hőrdőzótestet,amelynek az alakja megfelel az antennareflektőr alakjának.ŕThe subject of the invention is a method for producing an antenna reflector with excellent optical surface quality from a composite fiber material. During the procedure, uniformly synthetic plaster is melted on a film stretched in a flat position over a depression corresponding to the antenna reflector to be produced, and a negative mold corresponding to the shape of the antenna reflector to be produced, which is placed in the depression of the sheet, is pressed by the film heat until the synthetic gypsum clouded onto the film reaches the stable shape. After removing it from the main frame and removing the moisture, the reflector shell is fixed again on the negative main frame, and then a heat sink body, the shape of which corresponds to the shape of the antenna reflector, is fixed on the back side of the reflector.
