Fastener Product Cold Heading Process Formulation and Precision Die Design

Abstract

The stamping and forming process of the flat-head cross stainless-steel bolt was formulated and finite element simulation analysis was carried out, and the forming pressure required for the forming of cold heading stainless steel fasteners was obtained. On the basis of the results of the finite element analysis, two-dimensional and three-dimensional CAD aided design tools were used the double-station cold heading dies for screw punches are carried out. According to the two-dimensional general structure diagram, the overall structure of the die base is designed and determined, the design purpose of each part of the die is analyzed, and the elements such as the size and material of each part are determined. , Completed the design of the precision mold, the mold was successfully used in the enterprise, the production was good, and it created better benefits, providing a reference experience for the development of similar molds.
