Plate curved surface forming device for square pressure head adjustable mold

A plate curved surface forming device for square pressure head adjustable mold includes an upper group and a lower group of height-adjustable molds (4) and a loading mechanism. The adjustable molds (4) are mounted on the loading mechanism and at least one group of the adjustable molds (4) can be moved up and down under the drive of the loading mechanism. The upper group and the lower group of the adjustable molds (4) are respectively provided with M×N and (M-1)×(N-1) swinging square pressure heads (1). The upper group and the lower group of the square pressure heads (1) are arranged in a staggering way in both horizontal and longitudinal directions. The square head (1) is equipped with a square plate (a) and a ball (b). The pressurizing surface of the square pressure head (1) is a plane or a curved surface. The above mentioned device can eliminate corrugated deformation generated during the stamping process of the plate, reduce indentation, and improve the process quality.
