Pre-hollowed-out weight-reducing skin wallboard and forming method thereof

The invention relates to a pre-hollowed-out weight reduction skin wallboard and a forming method thereof, belongs to the technical field of shaping machining, and solves the problem that a machining process in the prior art cannot meet the requirement of a wallboard for a weight reduction area. The pre-hollowed-out weight-reducing skin wallboard comprises a skin, reinforcing ribs and a reinforcing frame, the reinforcing frame is arranged on one side of the skin, the reinforcing ribs are communicated in a criss-cross mode and arranged on one side of the skin, the reinforcing ribs are located in the reinforcing frame, each reinforcing rib is of a hollow structure, and the space between every two adjacent reinforcing ribs is of a hollow structure. The pre-hollowed-out weight-reducing skin wallboard is high in bearing capacity and remarkable in weight reduction effect. 本发明涉及一种预镂空减重蒙皮壁板及其成形方法，属于塑形加工技术领域，解决了现有技术中的加工工艺不能满足壁板对减重区的需求的问题。本发明的预镂空减重蒙皮壁板包括蒙皮、加强筋和加强框，所述加强框设于所述蒙皮的一侧，所述加强筋纵横交错连通并设于所述蒙皮的一侧，且所述加强筋位于加强框内，所述加强筋为
