Abstract
U ovom završnom radu bilo je potrebno, pomoću eksperimentalne analize, objasniti utjecaj trenja na silu deformiranja u procesu slobodnog kovanja te proračunati koeficijent kontaktnog trenja za različite odnose kontaktnih površina. U teorijskom dijelu ukratko je opisana pojava trenja, kako se ona očituje pri procesima oblikovanja metala deformiranjem, koje vrste trenja postoje te kako maziva mogu utjecati na njegovo smanjenje. Uz to, opisan je postupak oblikovanja kovanjem, a fokus je stavljen na proces slobodnog kovanja gdje uslijed djelovanja sile trenja na kontaktnim površinama alata i obratka dolazi do otežanog tečenja materijala te pojave bačvanja. Objašnjen je i raspored naprezanja na tlačnoj površini pravokutne prizme koji se kasnije u eksperimentalnom dijelu koristi za izračun koeficijenta trenja. Na temelju provedenog ispitivanja te sakupljenih informacija iz izvora literature, donesen je zaključak o utjecaju trenja na silu deformiranja nekog materijala.
Abstract (english)
In this thesis it was necessary, using experimental analysis, to explain the influence of friction on the deformation force in the process of free forging and to calculate the coefficient of contact friction for different contact surfaces. The theoretical part briefly describes the phenomenon of friction, how it is manifested in deformation forming technology, what types of friction exist and how lubricants can affect it. Also, the forging process is described, with the focus on free forging where, due to the action of friction forces between the tool and workpiece, there is a difficult material flow and the phenomenon of barreling. The stress distribution on the surface of a rectangular prism is shown, which is later used in the experimental part to calculate the coefficient of friction. A conclusion about the influence of friction on the deformation force was made based on the conducted research and the information collected from the literature.
