Modificirana izvedba priklopa hladilnega sistema
Modified version of the connection of the cooling system
Magistrska naloga zajema predelavo obstoječega sistema hlajenja tlačnega orodja na hlajenje skozi okvir. Ustrezno zasnovo novega sistema hlajenja se išče na različnih inženirskih področjih. Končno izvedbo novega orodja je treba primerjati z obstoječim, zato sta za primerjavo izvedeni toplotna in termomehanska analiza. Za konceptno rešitev tesnjenja na prehodu hladilno-ogrevalnih izvrtin iz okvirja na gravuro je bilo izbrano O-tesnilo, saj predstavlja najboljšo izbiro na podlagi ocenjevalne lestvice. Na podlagi meritev temperature na obstoječem orodju se je izkazalo, da so rezultati toplotne analize dober približek realnemu stanju. Iz primerjave toplotne analize obstoječega in novega orodja se vidi drugačna porazdelitev temperaturnega polja. Tudi termomehanska analiza pokaže razlike v porazdelitvi napetosti in večjih raztezkih na novem orodju.
The master thesis consists of a modification of an existing cooling system through the die casting tool outer die. Solutions for cooling system are searched in various fields of engineering. The final version of a new tool design needs to be compared with an existing one. For that reason, a heat transfer and thermomechanical analysis were needed for comparison between existing and new tool. For a conceptual choice that will guarantee a good sealing solution on a transition of cooling channels between outer and inner die, an O-ring was chosen as it presents the best solution based on the rating scale. Temperature measurements were performed in order to validate the results of heat transfer analysis. Based on that, we could confirm that the results from the analysis were a good approximation to real ones. The heat transfer showed the main differences between the existing and new tool. It showed how cooling channels affect the distribution of temperature over the tool. Due to this difference, it also affects the results of a thermomechanical analysis. The main differences are shown in the distribution of stresses and strains.
