Technology of production cover by forming

Master´s thesis project elaborated within the scope of Master´s degree submits a proposal of manufacture technologies for complicated components with the transition of an elliptical shell into a rectangular shape. Material: Aluminium EN: AW-3003, thickness 2 mm. Estimated annual production: 80 000 pieces. Drawing tool with blankholder was designed based on calculations and literature study of deep drawing. The drawing operation is performed by a hydraulic press ZH 50 with a rated power of 500 kN. The drawing tools are made from tool steel 1.2379 (19 573). Proposal of suitable technologies respectively drawing proces was verified by simulation program FormingSuite and PAM-STAMP
