Mandrel drawing

用法例句

3D finite element model of steel tube and internal-external die is created to simulate the whole process of tube plug drawing mill dynamically based on explicit dynamic module of ANSYS.

借助ANSYS软件显式动力模块建立了钢管与内外模具的三维有限元模型,动态模拟了短芯棒拔制的整个过程,研究了模锥角、摩擦系数、壁厚等工艺参数对拔制力的影响,并根据得到的应力分布规律分析了生产中拔断等实际问题的机理。

Aiming at different factors that affected wall thickness variation of the non-mandrel drawing steel pipe,through comparison testing,educed theory formula of wall thickness variation,and found out quantificationally mutative rules of the wall thickness for the different conditions in non-mandrel drawing process.

针对影响无芯棒拔制壁厚变化的各种因素,通过对比试验,推导出了壁厚变化的理论公式,定量的找出了各种状态下的无芯棒拔制壁厚变化规律,对指导冷拔钢管生产,拓宽冷拔生产规格,提高产品精度及开发新产品具有很重要的意义。

Non-mandrel drawing is a method widely used in cold drawn pipe production.

无芯棒拔制是冷拔钢管生产中应用最广泛的一种生产方法。
