V zaključni nalogi je predstavljena raziskava in analiza izdelave hladilnih reber iz aluminija s preoblikovalnim postopkom istosmernega iztiskavanja, ki bi lahko služila za hlajenje LED žarometov. Predstavili smo potek analiziranja vplivov tehnoloških parametrov in oblik po načrtu Taguchijeve ortogonalne matrike, eksperimente pa izpeljali s pomočjo simulacij, ki smo jih izvajali s programsko opremo QForm. Glede na najbolj ugodne rezultate smo postavili model, za katerega smo zasnovali in skonstruirali orodje. Za končan model orodja smo naročili material in poslali povprašanje za izdelavo lokalnim orodjarjem s ciljem realizacije izdelka. The thesis deals with the research and analysis of making aluminium cooling fins using the one direction extrusion process, the final product being utilized for cooling LED lights. The course of the analysis of impacts of technological parameters, as well as shapes, according to the Taguchi Orthogonal Matrix, has been presented. The experiments were carried out in the form of simulation, using the QForm software. According to the optimal results a model has been formed, along with the design and construction of the tools for its fabrication. Finishing the ultimate model of the tools was followed by commission of the material and inquiry among the local toolmakers in order to finalize the project.
