Numerical Investigation of Fine Blanking of a Helical Gear

摘要：

　　Fine blanking, as an effective and economy metal forming process, can be used for the manufacturing of helical gears with inclined forming movement.In the present study, a reliable three-dimensional (3D) rigid-plastic finite element (FE) model is developed on the DEFORM-3D platform for rotational fine blanking of a helical gear.Based on this FE model, distributions of different field variables such as metal flow velocity, mean stress and effective strain are obtained, and cut surface features and punch stroke curve are predicted.The results achieved in this study can not only evaluate the capabilities of the rotational fine blanking process of a helical gear, but also provide valuable guidelines and a better understanding of the deformation mechanism of this process.
