Vplyv technologických parametrov pri prievlačnom ťahaní rúr na ich výsledné vlastnosti a presnosť

Abstract

The article is focused on the implementation of experimental tests in order to monitor the impact of technological parameters during the drawing of tubes on their resulting properties and accuracy. In experimental tests, samples of seamless tubes with dimensions of Ø14, Ø16 and Ø18 were used, which were pulled by pressing to the final outer diameter of Ø12. Measurements of internal and external diameter as well as tensile tests to determine mechanical properties were carried out before and after drawing on the tubes. Experimental tests were carried out in order to optimize the drawing process to reduce the number of operations and reduce production costs.
