Abstract

Metal forming has played a significant role in manufacturing development, thus investigations in the field of metal forming to improve the quality of the forming process are necessary. In the present study, the experimental and numerical analysis of airfoil contour forming of 301 austenitic stainless steel is examined in order to reduce the spring reversible ability under preheat temperature.

Considering the stress-strain properties of the preheat temperature; the body forming is simulated in ABAQUS software according to the theory of increasing the blank holder force during forming.

The obtained results of the spring-back for simulating the austenitic stainless steel airfoil are compared and investigated with the manufactured experimental sample results using deep tensile forming.

By comparing the results it can be seen that the control of blank holder force during forming cause to minimize the spring-back effects.

考虑回弹的301奥氏体不锈钢翼型成形模拟与实验研究

金属成形在制造业的发展中起着重要的作用，因此有必要对金属成形领域进行研究，以提高成形过程的质量。为了降低预加热温度下的弹簧可逆能力，对301奥氏体不锈钢翼型轮廓成形进行了实验和数值分析。考虑预热温度的应力-应变特性;根据成形过程中加大压边力的理论，在ABAQUS软件中对阀体成形过程进行了仿真。将得到的模拟奥氏体不锈钢翼型的回弹结果与用深度拉伸成形制造的实验样品结果进行了对比研究。通过对结果的比较可以看出，在成形过程中控制压边力可以使回弹效应最小化。
