AI Technical Summary

Technical Problem

Traditional large-scale cylindrical winding molds lack rigidity, cannot meet the design requirements of ultra-large cylindrical bodies, and have a large self-weight, which affects the product molding quality.

Method used

The frame-type cylindrical winding molding mold adopts a structure without an intermediate mandrel. The shell plate is supported by support frames at both ends and support flanges. Combined with the segmented shell plate structure and longitudinal rib connection, the overall rigidity is enhanced, and the rigidity of the mold is improved by diagonal support.

Benefits of technology

While reducing the weight of the mold, it significantly improves the rigidity and ease of assembly, making it suitable for mass production of large composite material cylinders.

Abstract

The application discloses a frame type cylinder winding forming die, which comprises a frame type middle section, symmetrically arranged end covers connected to two ends of the frame type middle section, a mandrel arranged at the center of the end cover, a middle section shell plate connected to the outer surface of the frame type middle section, and an end cover shell plate arranged on the end cover. The winding die adopts a structure without an intermediate mandrel, greatly reducing the self weight, and is supported by two side support frames, increasing the shell rigidity. The die shell adopts a split type structure, being easy to assemble and disassemble. Meanwhile, the frame type middle section structure is adopted in the shell, the ring frame and the longitudinal rib are connected and positioned through the positioning holes in the ring frame, and the shell plate is connected with the ring frame through bolts, greatly improving the shell plate rigidity and the winding die rigidity and simplifying the installation process. The application can realize the winding forming process of a large length and large diameter cylinder.
