摘要:

针对椭圆形封头热冲压成形过程中封头局部厚度出现减薄、增厚等问题,采用Deform软件对椭圆形封头热冲压成形过程进行三维有限元分析,得到不同温度下封头的等效应力、等效应变和厚度沿坯料半径的分布情况,并依据GB/T 1503—2011对封头厚度进行计算,得出制造封头最优的载荷力和工作环境温度参数。最后,利用4500 t封头液压机进行冲压制造,得到的封头的厚度分布与模拟结果基本一致。结果表明:在热冲压成形过程中,在坯料半径150~300 mm处的封头的等效应力、等效应变出现急剧变化,成形后的最大变化值位于直边段部位,此处受力最为薄弱。对于S30403不锈钢板材,当坯料温度为1000 ℃时,成形后椭圆形封头厚度的变化最为理想,封头质量较好。

For the problems such as thinning and thickening of the local thickness for oval head in the hot stamping process, the three-dimensional finite element analysis on the hot stamping process of oval head was conducted by software Deform, and the distributions of equivalent stress, equivalent strain and thickness of head along the radius of blank at different temperatures were obtained respectively. Then, the thickness of head was calculated according to GB/T 1503—2011, and the optimal load force and working environment temperature parameters of manufacturing head were obtained. Finally, the head was formed by a 4500 t head hydraulic press, and the thickness distribution of head was basically consistent with the simulation result. The results show that during the hot stamping process, the equivalent stress and equivalent strain of head at 150-300 mm of blank radius change sharply, and the maximum change value after forming is located at the straight edge section, where the force is the weakest. For S30403 stainless steel sheet, when the blank temperature is 1000 ℃, the thickness change of oval head after forming is the most ideal, and the head quality is better.
