20.500.12556/DKUM-75008 Vpliv radija pestiča in širine materiala na elastično poravnavanje pri procesu upogibanja diplomsko delo The effect of punch radius and material width on springback in bending process Diplomska naloga opisuje proces upogibanja, ki velja za enega najbolj razširjenih tehnoloških postopkov za preoblikovanje pločevine. Namen diplomskega dela je z eksperimentalnim delom ugotoviti, kako nekateri geometrijski parametri vplivajo na elastično poravnavo pri upogibanju po razbremenitvi. Rezultati eksperimentalnega dela, ki so prikazani v obliki grafov in preglednic ter so primerjani z analitičnimi preračuni, so pokazali, da je vpliv radija pestiča na velikost elastične poravnave zelo velik, medtem ko širina komada nima pomembnejšega vpliva na elastično poravnavanje. The thesis describes the bending process, which is considered as one of the most widespread technological processes for sheet metal forming. The purpose of this diploma thesis is to find out how some geometrical parameters affect the springback after unloading the material. I tried to find out the latter with experimental work. The results of the experimental work, which are presented in the form of graphs and tables are compared with analytical calculations. They showed that the influence of the radius of the punch on the size of the springback is large, while the width of the piece has no significant effect on the springback. upogibanje pločevine radij pestiča elastična poravnava kot zravnanja bending process punch radius springback springback angle true true false [J.
