“…In the case addressed in the paper, tube bending with local induction heating was analysed by application of the finite element method, using version 12 of the Simufact Forming software package from MSC.Software. This software is used for numerical modelling of complex forming processes, and the results obtained by that means display high conformity with the relevant experience [8,[10][11][12].…”

This paper addresses numerical analyses of the bending process for tubes made of the X70 steel used in gas distribution pipelines. The calculations performed under the research involved simulation of processes of tube bending with local induction heating. The purpose of these calculations was to establish process parameters making it possible to develop pipe bends of geometric features conforming with requirements of the applicable standards. While performing the calculations, an analysis was conducted to determine the probability of occurrence of folding and fractures according to the Cockcroft-Latham criterion.

“…The parts are cut off in sizing zone by the ribs on the rolls [36]. SR is also called "helical rolling" and is mainly adopted in the production of short rotational parts, such as steel balls [37].…”

Shaft part rolling is an efficient and green nearnet shaping technology offering many advantages, including high production efficiency, high material utilization rate, high product quality, and excellent production environment. In this paper, the features of shaft part rolling are introduced along with the working principles of two main shaft part rolling technologies, namely, cross wedge rolling (CWR) and skew rolling (SR). In relation to this technology, some R&D achievements gained by the University of Science and Technology Beijing are summarized. Finally, the latest developments in shaft part rolling are presented, including SR steel balls, precise forming of camshaft blank by CWR, SR phosphorous copper balls at room temperature, and CWR hollow axle sleeve. Although the shaft part rolling technology has been widely used in China, it only accounts for about 15% of applicable parts at present. Nevertheless, this technology has broad application prospects.

“…The technique is based on the use of wedges with helical grooves which are mounted on the rolls to ensure that parts are formed in a continuous manner. The numerical results and experimental findings demonstrate that helical wedge rolling is a viable technique for forming balls [60,63,68,85,99,101,134,136]. Figure 19 shows the tools used in the HWR for balls and semi-finished balls.…”

The paper overviews the research on roll forging processes in the last two decades. Given the broad scope of this problem, the overview focuses on processes in forging plants, omitting those performed in metallurgical plants. Three rolling processes are discussed in detail: longitudinal rolling, cross rolling and helical rolling. Each of the three techniques is discussed in terms of the main research problems and potential directions of future development.
