Abstract
Broni se uporabljajo za izdelavo orodij za litje ali brizganje plastike, kadar je potrebno hitrejše in učinkovitejše odvajanje toplote. V zadnjem času na veljavi pridobivajo aditivne tehnologije, s katerimi lahko izdelujemo tudi različna orodja. Tak proces je tudi robotsko oblikovno obločno navarjanje (angl. Wire Arc Additive Manufacturing), ki omogoča izdelavo multi-materialnih izdelkov. Prednosti tega so lahko hitrejša izdelava ter manjša poraba energije in materiala, ki lahko omogoča prihranke na času in stroških izdelave. Prednosti tega so lahko hitrejša proizvodnja in manjša poraba energije in materialov, kar lahko prihrani čas in stroške proizvodnje. V okviru naloge je bil s postopkom WAAM navarjen aluminijev bron (CuAl8) na orodni vložek iz maraging jekla, ki je bil izdelan z uporabo selektivnega laserskega taljenja (SLM). Pripravljen je bil eksperimentalni načrt oblikovnega obločnega navarjanja, kjer smo med obdelavo spremljali temperaturo in parametre WAAM. Narejen in analiziran je bil izračun tehnoloških vrednosti in proizvodnih stroškov. Ugotovljeno je bilo, da je postopek WAAM uspešno izveden, če je minimalna medvarkovna temperatura med 220 in 300 °C. Pri zelo visokih temperaturah pride do prekomernega pregrevanja izdelka, kar spodbuja razlivanje nanešenega materiala.

Secondary title: |
Shape surfacing of aluminum bronze CuAl8 |
Secondary abstract: |
Bronze is used as material to produce casting tools or tools for injecting melding when faster and more efficient heat dissipation is required. Recently, additive technologies are gaining importance in the manufacturing of various tools. Wire Arc Additive Manufacturing (WAAM) enables also the production of multi-material products. The advantages of this can be faster production and lower consumption of energy and materials, which can save time and production costs. As part of the task, WAAM of CuAl8 was done on a tool insert made of maraging steel using a Selective Laser Melting (SLM). An experimental plan of WAAM was prepared, where temperature and WAAM parameters were monitored during processing. A calculation of technological values and production costs was done and analyzed. It was found that the WAAM process is successfully done if the minimal inter-layer temperature is between 220 and 300 °C. At very high temperatures, excessive overheating of the product is done, which promotes spillage of the deposited material |
