Abstract
A curved surface forming device for an adjustable segmented mold board with square rams, consisting of an upper group and a lower group of adjustable molds (4) whose height can be adjusted, and a loading mechanism. The adjustable molds (4) are arranged in the loading mechanism and at least one group of adjustable molds (4) can move 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) square rams (1) capable of swinging. The upper and the lower square rams (1) are arranged in an interlaced manner in both transverse and longitudinal directions. The square rams (1) are composed of a square plate (a) and the sphere (b) with the pressure imposition surface being a plane or a curved surface. The curved surface forming device can eliminate the crumpling and deformation generated in the board punching, reduce dents and improve processing quality.
