Design of a Flange Socket Mold and Improvement of Production Process

Abstrac t. Flange socket is a socket fittings which require a higher production process, and has a large market demand. The complex external shape, high precision connecting parts are very difficult to process. The traditional production engineering caused a great waste of materials and is very low efficient, and the work piece is easy to produce stress concentration. The cold extrusion forming and cutting compared to save raw materials and parts with better performance, longer life. In this paper, a flange socket mold is designed and extrusion forming process is developed through numerical experiments , and the process finally achieved the design requirements.
