Abstract
U uvodnom dijelu rada obrađene su teorijske osnove oblikovanja metala deformiranjem. Prikazane su fizikalne pojave u mikrostrukturi metalnih materijala prilikom deformacije i osnove teorije plastičnosti i trenja pri oblikovanju metala deformiranjem. Navedeni su osnovni modeli ponašanja materijala prilikom deformacije koji se koriste za proračune i MKE analizi naprezanja i deformacija. Osnova rada sastoji se od konvencionalnog proračuna sile sabijanja aluminijskog valjčića u hladnom stanju na različite visine sabijanja i MKE analize sabijanja te usporedbe dobivenih rezultata. Sila sabijanja je jedan od glavnih parametara za izbor stroja i ima veliki utjecaj na trošenje alata. Točan proračun sile sabijanja dovodi do bolje tehnologičnosti postupaka oblikovanja metala deformiranjem, a sa povećanom dostupnosti programskih paketa i računalne moći MKE analiza omogućava točniji proračun sile sabijanja.
Abstract (english)
In the introductory part of the paper, the theoretical foundations of metal forming are discussed. Physical phenomena in the microstructure of metallic materials during deformation and the basics of the theory of plasticity and friction in metal forming are presented. The basic models of material behavior during deformation used for calculations and FEM analysis of stresses and strains are given. The basis of the work consists of a conventional calculation of the compression force during cold upsetting of aluminum cylinders at different compaction heights and comparison of the results obtained by FEM analysis. Compression force is one of the main parameters for machine selection and has a great impact on tool wear. Accurate compression force calculation leads to better manufacturability of metal by forming processes, and with increased availability of software packages and computer power, FEM analysis enables more accurate compression force calculation.
