Abstract

Lijevanje u pijesak kao postupak praoblikovanja metala koristi se već tisućama godina za proizvodnju komponenata svih veličina i oblika. Postupak lijevanja moguće je prilagoditi kako uporabi u ljevaonicama sa isključivo ručnim radom tako i uporabi u visoko automatiziranim ljevaonicama gdje je ručni rad sveden na minimum. Cilj ovog rada je osmisliti i konstruirati postrojenje za pripremu kalupne mješavine pijeska u malim ljevaonicama koja bi smanjila količinu ručnog rada, podigla kvalitetu pijeska i time povećala konkurentnost tvrtke vodeći računa o tome da postrojenje bude jednostavno i povoljno za izradu, uporabu i održavanje. U radu su navedene teorijske osnove lijevanja, detaljno je prikazan primjer iz prakse, razrađena je ideja postrojenja i prikazan je proračun kritičnih dijelova postrojenja.

Abstract (english)

Sand casting as a process of primary shaping of metal has been used for thousands of years for manufacturing components of all sizes and shapes. Casting process can be adjusted for use in foundries with manual labor only as well as in highly automated foundries where manual labor is minimized. Purpose of this thesis is to design sand preparing plant which would reduce the amount of manual labor, improve sand quality and increase company competitiveness having in mind that plant should be simple and cost effective to manufacture, use and maintain. In this thesis theoretic basics are listed, examples from practice are shown in detail, the idea of plant design is developed and calculations of critical components have been conducted.
