Analiza vtisa vijakov gravurnih delov v tlačnih orodjih za litje aluminija : diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje Strojništvo - Projektno aplikativni program
Mesec, Aljaž
Vijaki, ki držijo gibljivo gravuro v okviru tlačnega orodja za litje aluminija, so med izmetovalnim ciklom podvrženi visokim silam. Porodilo se je vprašanje, ali se pod glavo vijaka pojavi tako velik ...površinski tlak, da pride do vtisa. V primeru vtisa bi lahko prišlo do netočne izdelave ulitkov izven toleranc. Izmetovalno silo smo merili z piezoelektričnim napetostnim senzorjem. ki smo ga montirali na izmetovalni drog. Ko smo dobili podatke meritev, smo v programu ABAQUS simulirali, kako se izmetovalna sila porazdeli po vijakih. Program ABAQUS nam je podal maksimalen površinski tlak pod vijakom, ki smo ga nato preverili na dopustnem površinskem tlaku in ugotovili, da ga ne presega. Poleg površinskega tlaka smo izrisali deformacijski diagram vijačne zveze, pri čemer smo ugotovili, da se v najbolj obremenjenem vijaku ob izmetovalnem ciklu tesnilna sila ohrani.
