Abstract
Prvi zastavljen problem zaključne naloge je vzpostaviti celoten proces kovanja v vročem za zahtevan izdelek. Kot nadaljevanje je sledila energijska optimizacija celotnega postopka. Potrebna je bila teoretična določitev parametrov, ki so vezani na materialne lastnosti in končno obliko kovanega izdelka, sledilo je modeliranje orodja v modelirniku SolidWorks, ter uvoz skice posameznih orodij in simulacija v programskem okolju QForm. Za voljo iskanja optimalne temperature celotnega postopka, je bila simulacija izvedena pri različnih temperaturah. Postopek, ki je obsegal simulacije v temperaturnem območju od 700°C do 1250°C, je potrdil predvidevanja, in sicer, da je optimalna temperatura izvedbe celotnega postopka, ko je surovec segret na začetno temperaturo 700°C. To pa zato, ker se večinski delež energije porabi za začetno segrevanje.

Title:Optimisation of multi-stage hot forging in terms of process energy efficiency
Abstract:
The first set problem of the diploma thesis is to establish the entire hot forging process for the required product. As a continuation, the energy optimization of the entire process followed. It was necessary to theoretically determine the parameters related to the material properties and the final shape of the forged product, followed by tool modeling in the SolidWorks modeler, and the import of individual tool sketches and simulation in the QForm software environment. In order to find the optimal temperature for the entire process, the simulation was performed at different temperatures. The process, which included simulations in the temperature range from 700°C to 1250°C, confirmed the predictions, namely that the optimal temperature of the entire process is when the raw material is heated to an initial temperature of 700°C. This is because the majority of energy is used for initial heating.

Keywords:energy optimization, hot forging, QForm programming environment, stress in the tool
