AI Technical Summary
When changing the existing bending die to stamp different shaped plates, it is necessary to disassemble and install modules and die slots, resulting in low work efficiency.
A mold structure was designed that enables rapid replacement of modules and mold slots through the combination of components such as limiting posts, sleeves, sleeve grooves, and hydraulic rods. Magnetic blocks are used to enhance the stability of the limiting posts, while sleeves and rotating rudders improve the ease of operation. Manganese steel is used to enhance the toughness and restoring properties of the springs.
It enables quick mold changes when stamping sheet metal of different shapes, improving work efficiency and enhancing mold stability and ease of operation.
