APPARATUS FOR DIELESS FORMING PLATE MATERIALS

摘要

An apparatus for dieless forming plate materials, generally comprising a pressure mechanism adapted to be moved in the directions of three axes X, Y, Z, a plate material retaining mechanism, a position-fixed top plate mold, the shape in plan of which is in agreement with a contour of a bottom surface of a product to be molded, a frame type support plate surrounding the top plate mold and adapted to be moved vertically by at least a pair of lifting actuators, and a frame type holding plate adapted to clamp a circumferential portion of the plate material along with the support plate in the direction of the thickness thereof and capable of being variably controlled in terms of a holding force thereof by a holding actuator, and preferably, in addition to these parts, a mechanism for moving the support plate in a balanced state, and a mechanism for controlling the fluidity of a material.
