Research on stamping formability for hood inner plate of aluminum alloy
The use of aluminum alloy material in the hood design aimed to improve the stamping forming quality of the hood inner plate,a complete process supplement surface model was built by planning the stamping direction and designing reasonable process supplement surface and drawing bead,etc.,AutoForm software was used to simulate and verify the stamping process of the hood in-ner plate to ensure the feasibility of the design scheme.Based on the simulation results,a specific formability improvement scheme was proposed and implemented to solve the problems encoun-tered in the stamping process of the front hood inner plate.The best reference value of the die de-moulding angle was 55°at the windshield of the front hood inner plate of the aluminum alloy,which provided reference for the process design and forming optimization of the hood inner plate of the aluminum alloy.
