摘要

PURPOSE: A sheet molding apparatus including a plurality of forming punches controlled by less punch regulating motors and a sheet molding method using the same are provided to form sheets of various sizes and thicknesses to have single, double, or multiple curvature by increasing the load bearing power. CONSTITUTION: A sheet molding apparatus includes a plurality of forming punches and one or more punch regulating motors. Each of the forming punches(1) comprises a punch head, a hollow outer member with inner thread, and an inner member with outer thread inserted into the outer member. One of the outer and inner members is connected to the punch head while the other is connected to a rotary shaft(11). The punch regulating motor engages with the rotary shaft of each forming punch to provide torque.
