摘要
介绍了编制低残余应力HSn70-1圆管拉拔配模规程的设计和计算方法,并提出根据变形参数KF预报(估计)HSn70-1圆管的残余应力σθ值的线性回归公式。文中介绍的具体方法,为编制其他合金半硬成品管免去低温消除残余应力的退火工序创造条件,是节能的一项"软技改"措施,值得试用和推广。
The design and calculation method for formulating the regulations for selecting dies for drawing HSn70-1 tubes with low residual stress are introduced. It is also pointed out that according to the deformation parameter Kf, the linear regression formula of the stress is predicted or estimated. The concrete method described will help create conditions for avoiding annealing steps for other half hard alloy tubes. Therefore, it proves to be an innovation deserving trial use and introduction.
