Abstract
Various industries, including mechanical engineering, utilize steel rings featuring variable cross-sectional profiles, such as eccentric rings. Presently employed methods for producing eccentric rings possess drawbacks like restricted geometries, significant material wastage or uneven microstructures. The radial–axial ring rolling process serves to create seamless rolled steel rings with near-net-shaped cross-sections. A novel technique involves achieving eccentricity by dynamically adjusting the mandrel’s position during the ring rolling process. This method’s fundamental feasibility has previously been showcased using a blend of oil clay and a labor test bench. Transferring the possibility of manufacturing eccentric rings on industrial radial–axial ring rolling mills would expand the product range of ring manufacturers without encountering drawbacks associated with existing manufacturing processes. The objective of this paper is to demonstrate the basic feasibility of the concept of an industrial radial–axial ring rolling mill. In the first step, FEA simulation studies were carried out to develop the rolling strategy and estimate the achievable eccentricity on the institute’s radial–axial ring mill. Subsequently, the rolling strategy was implemented on an industrial ring rolling mill with the help of a unique technology module programmed in C++. Finally, an eccentric ring was ring rolled and compared with the FEA simulation, and the reproducibility was demonstrated to be successful.
包括机械工程在内的各行各业都在使用具有可变截面轮廓的钢环,如偏心环。目前采用的偏心环生产方法存在几何形状受限、材料浪费严重或微观结构不均匀等缺点。径向-轴向环形轧制工艺可生产出横截面接近网状的无缝轧制钢环。一种新颖的技术是在轧环过程中通过动态调整芯轴的位置来实现偏心。这种方法的基本可行性此前已通过使用混合油粘土和劳动试验台进行了展示。在工业径向轴向轧环机上制造偏心环的可能性将扩大环制造商的产品范围,而不会遇到与现有制造工艺相关的弊端。本文旨在论证工业径向轴向轧环机概念的基本可行性。首先,进行了有限元分析模拟研究,以制定轧制策略并估算研究所径向轴向环轧机可达到的偏心率。随后,在用 C++ 编程的独特技术模块的帮助下,在工业环轧机上实施了轧制策略。最后,对偏心环进行了环轧制,并与有限元分析模拟结果进行了比较,证明其再现性是成功的。
