【摘要】 针对TC4钛合金管件的径向精锻,根据其工艺特点进行了简化建模,利用数值模拟软件Deform 3D对管件径向精锻过程进行了数值模拟,通过其成形过程的应力、应变分布特征,分析钛合金管的成形特点;通过坯料金属流动的速度场分布,分析该零件成形过程及特点。通过其行程———载荷曲线,进行成形力预测,对实际生产过程具有较大的意义。进行了模具受力分析,对模具寿命的预测有一定帮助。在该管件的数值模拟基础上进行了生产试制,试件产品成形顺利,质量良好。

【Abstract】 Aiming at the radial precision forging of Titanium alloy tube of TC4,based on its technical characteristic,the simplified modeling is done.Using the FEM software Deform 3D simulates the process of the titanium tube radial precision forging.By the Stress and strain distribution characteristic during deformation,its forging characteristic is analyzed.The velocity distribution of the blank is used to analyze the process of the deformation.The forging force is predicted by the stroke-force curve,which has a great significance to the real manufacture.The bearing force of the die is analyzed,that is helpful to the prediction of the die service life.Based on this result,the trial-manufacture is carried out whose product is of good quality.
