本文通过穿孔辊辊型的讨论指出,由于曲线轧辊的使用条件苛刻,这种轧辊适用于斜轧角α为常数的生产厂。随着α角调整方便的现代穿孔机在生产中的应用,α角将变成一个可变的参数,此时辊型简单的圆锥型轧辊(即折线式轧辊)反而具有更强的适应能力。为了正确使用圆锥型轧辊,有必要建立一套简单而易行的有效辊型计算方法。本文鉴于这样一个目的,提出了圆锥型穿孔辊出口锥有效辊型的计算原理与方法。有效辊型是正确计算穿孔调整参数的依据,而穿孔调整参数的正确与否又关系到穿孔调试过程的长短,减少调试中管坯的损失,这一问题对多规格穿孔轧制的生产厂而言尤为重要。
This article through the discussion of perforated roller type pointed out that due to the harsh conditions of the use of curved rollers, this type of roller is suitable for the production of a constant angle of roll angle α. With the use of a modern perforator with easy adjustment of α-angle, α angle becomes a variable parameter, and conical roller with simple roller profile (ie, fold line roller) can be more adaptive. In order to correctly use conical rolls, it is necessary to establish a simple and easy-to-use method of calculating effective rolls. In view of such an objective, this paper proposes the calculation principle and method of the effective roller shape of conical perforated roller outlet cone. The effective roller type is the basis for the correct calculation of perforation adjustment parameters. The correctness of the perforation adjustment parameters is related to the length of the perforation adjustment process, which reduces the loss of the tube during commissioning. Words are especially important.
