Výroba švových rúr malých priemerov z austenitických ocelí

Abstract

The article focuses on the analysis of the production process of small diameter seam tubes made of austenitic steels used in the food industry, automotive and aerospace industries, in measurement technology, heating elements, in healthcare in the production of needles for syringes, for heat exchangers designed to cool exhaust gases in the automotive industry and for fuel-oil heat exchangers used in the aerospace industry. The article deals with the production of precision seam tubes with a diameter of 6 mm and a wall thickness of 1 mm. The aim was to optimize the process using simulation using the DEFORM 3D simulation program. The solution consisted in adjusting the geometry of the beam and improving the friction ratios during the drawing.
