The simulations of single and multi pass drawing tube processes were carried out.
借助有限元分析软件模拟了 316 L 不锈钢管的拉拔过程 ,比较了单道次拉拔与多道次拉拔对残余应力场的影响 ,发现在变形量相同的条件下 ,单道次拉拔引发的残余拉应力较小 ,且分布较均匀。
The dynamic models and elasto-plastic finite element models of the non-plug and with-plug processes were established for the two-pass drawing process of an aluminium tube from circular to rectangular section,and then the simulation was performed.
针对铝合金管由圆形截面变形至矩形截面的两道次拉拔过程,相应建立了空拉拔和带芯头拉拔工艺的运动模型及弹塑性有限元模型,并进行了模拟分析。
It is pointed out that the fine stainless steel wire produced by melting drawing can only be used to some realms having not high requirements because of its section being shaped;the fine stainless steel wires produced by clustered drawing method have not uniform shape,uniformity and precision are worse,and the length of the fine wire is limited;the single wire drawing is.
介绍不锈钢极细丝的生产方法、热处理工艺及生产中存在的问题,指出采用熔抽法制成的不锈极细丝,横截面多为异形,只能用于一些要求不高的领域;集束拉拔法生产的不锈极细丝形状不一致,均匀性和精度较差,并对极细丝长度也有一定限制;单丝拉拔法是高档次、高精度不锈极细丝的主要生产方法,国内企业应加紧0。
