摘　　要：为改善低合金钢冷成型制造封头后残余应力的不利影响,需要对其进行消应热处理。采用三维软件建模和有限元方法,对封头消应热处理过程进行模拟计算。结果表明,随着支撑杆数量的增加,开孔接管封头热处理形变量不断减少。随着支撑杆规格的增大,开孔接管封头热处理形变量不断减少,但形变量变化不如增加支撑杆数量的效果明显。随着支撑板尺寸的增大,开孔接管封头热处理形变量先减少后基本保持不变。对于封头规格为EHA2000×12、接管规格为?219×10的开孔接管封头,最优的减小消应热处理形变量的工装设计为布置?48 mm规格的8根支撑杆,同时其支撑板尺寸为100 mm×100 mm。In order to improve adverse effects of residual stress after cold forming of low alloy steel heads,it is necessary to perform stress relief heat treatment on the formed head.Three dimensional software modeling and finite element method are used to simulate the stress relief heat treatment process of the head.The results show that with the increase of the number of support rods,the deformation of the heat treatment of the opening nozzle head decreases continuously.With the increase of the size of the support rods,the heat treatment deformation of the opening nozzle head decreases,but the effect of reducing deformation is not as obvious as increasing the number of support rods.With the increase of the size of the support plate,the heat treatment deformation of the opening nozzle head first decreases and then remains basically unchanged.For the opening nozzle head with head specification of EHA2000×12 and nozzle specification of Ф219×10,the best tooling to reduce the deformation of stress relief heat treatment is the layout of the 8 support rods with specification of Ф48 mm,and the size of support plate is 100 mm×100 mm.
