SUMMARY:Accuracy of skew rolled railway axle forgings
DESCRIPTION:The forming of railway axles is carried out using forming techniques. Rotary forging and open forging are used to produce railway axles. However, in order to increase the efficiency of the process by reducing the time needed to manufacture the product, as well as its energy intensity, it is necessary to propose an alternative forming method. To this end, research work is being carried out at the Lublin University of Technology, including the development of cross wedge rolling technology using flat tools, as well as skew rolling using three cone rollers. A test stand in the form of a numerically controlled inclined roller mill has been developed, enabling the forming of products whose final shape is obtained as a result of the sequential movement of three work tools. The machine developed is characterised by its high versatility of use due to the numerical control system used, which makes it possible to manufacture products on the basis of their envelope outline. The aim of the study was to analyse the geometric dimensions of the railway axle forgings obtained by the skew rolling method. Measurements were taken of the shape deviations, including the roundness of the individual steps, as well as the straightness of the axles. A non-contact measuring method using the GOM Scan 1 optical measuring system was used.
