The Flat Wedge Rolling Mill for Forming Balls from Heads of Scrap Railway Rails

The paper describes the design of a flat-wedge reversing mill used for forming balls directly from heads of scrap railway rails. At the beginning an innovative rolling method for producing balls is presented. This two-stage method consists in forming balls from heads of scrap railway rails using plate-shaped flat tools. The first stage involves preparation of a workpiece by changing the irregular shape of the rail head into a round bar. Next, the workpiece is automatically moved to the working space of the other tool set, where forgings of balls are formed on return motion of the slide. To enable the production of balls under industrial conditions in accordance with the above concept, a flat-wedge rolling mill was designed and constructed. The results demonstrate that the machine can be used to produce balls from heads of scrap railway rails.
