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, comprising an upper group and a lower group of square rams, height adjustable molds and a loading mechanism, wherein the upper group and the lower group of adjustable molds are arranged in the loading mechanism and at least one group of the adjustable molds can move up and down under a drive of the loading mechanism;

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