Abstract
U ovom radu opisano je sabijanje aluminijskih valjčića koristeći gravitacijski bat te utjecaj njegovih parametara na plastičnu deformaciju valjčića tijekom hladnog sabijanja. Parametri koje su uzeti u obzir su masa i visina. Osim toga, objašnjeno je koji su načini deformiranja te vrste kovanja. Naglasak je stavljen na strojeve koji se koriste za postupke oblikovanja, a osobito na gravitacijski bat s obzirom na činjenicu da je isti korišten za provođenje eksperimenta. Eksperimentalni dio rada opisuje tijek provedenog eksperimenta. Naime, sabijano je šest aluminijskih valjčića jednakom potencijalnom energijom no uz različite brzine udara. Rezultati ispitivanja prikazani su tablično i uz pomoć dijagrama kako bi se ukazalo na ovisnost logaritamskog stupnja deformacije o brzini udarca malja.
Abstract (english)
This thesis describes the compression of aluminium billets using a gravity drop hammer and the influence of its parameters on the plastic deformation of cylinders during cold upsetting. Parameters that were considered are mass and height. Also, the ways of deformation and types of forging are explained. Emphasis is placed on the machines used for forming processes, and especially on the gravity drop hammer, considering the fact that it was used to conduct the experiment. The experimental part of the work describes the planning of the conducted experiment. Namely, six aluminium billets were compressed with the same potential energy but with different impact speeds. The test results are presented in a table and a diagram to indicate the dependence of the logarithmic degree of deformation on the hammer impact speed.
