through the reduction of friction force and deformation force between the steel wire and die, the tensile failure problem of steel wire workblank during the stamping process was resolved.
存在的主要问题是在沖压过程中钢丝坯料易被拉断,通过减小钢丝和模具间的摩擦力及变形力解决了问题。
finite element modelling was used to predict possible problems during stamping process and feasible shape and dimensions of workblank were obtained.
