Curved surface forming device for adjustable segmented mold board with square rams

A curved surface forming device for an adjustable segmented mold board with square rams, essentially consisting of an upper group and a lower group of square rams (1) capable of swinging, height adjustable molds (4) and a loading mechanism, wherein the upper group and the lower group of adjustable molds (4) are arranged in the loading mechanism and at least one group of the adjustable molds (4) can move up and down under the drive of the loading mechanism;

• characterized in that the adjustable molds (4) are provided with a group of square rams (1) in the quantity of M×N capable of swinging installed on the supporting body (2) in the fixing frame (3), forming the lower or the upper adjustable molds (4);
• and a group of square rams (1) in the quantity of (M−1)×(N−1) capable of swinging installed on the supporting body (2) in the fixing frame (3), thus forming the upper or the lower adjustable molds (4);
• the height of each square ram (1) in the upper and the lower adjustable molds (4) can be adjustable, and the square rams (1) of the upper and the lower adjustable molds (4) are arranged in an interlaced manner in both transverse and longitudinal directions;
• the square rams (1) are composed of two parts:
• the square plate (a) and the sphere (b);
• one side of the square plate (a) is pressure imposition surface and the other side is the sphere (b);
• the pressure imposition surface of the square plate (a) is a plane or spherical surface;
• when the pressure imposition surface of the square plate (a) is a plane, the edge part of the pressure imposition surface can be provided with a taper or arc (c);
• the sphere (b) is located on the inner end concave spherical surface of the supporting body (2), and is flexibly coupled with the square rams (1) via the spring 8.
