V magistrski nalogi je predstavljena tematika razvoja novega zavornega pedala, katerega bi v velikih serijah štancali s progresivnim preoblikovalnim orodjem. Obravnavana je zasnova prototipnega preoblikovalnega orodja s postopkom izdelave metodnega plana in konstruiranja posameznih preoblikovalnih operacij. V fazi razvoja novih izdelkov in preoblikovalnih orodij se v podjetjih vse bolj uporabljajo računalniško podprte simulacije, s katerimi se skrajšajo časi preizkusov in znižajo stroški le-teh. Izdelali smo simulacijo štirih preoblikovalnih operacij, ki so potrebne za izdelavo zavornega pedala. Analizirali smo napetosti in deformacije, ki se pojavijo med preoblikovanjem in jih primerjali med dvema različnima materialoma. Simulirana je tudi statična obremenitev na zavorni pedal, ki bi se pojavljala v realnosti za aktivacijo zavore. In this thesis the topic of a new break pedal production using progressive forming tool is presented. The design of the prototype forming tool is discussed using methodical plan and construction of individual forming operations. Computer aided simulations are being increasingly used in the development phase of new products and forming tools, which shortens testing times and reduces production costs. One of the main objecives of this thesis was to develope simulations for four forming operations, that are used to produce the prototype break pedal. With this simulations we analysed stresses and strains that occur during forming of two different materials. Additionally we simulated static loading on the break pedal, which would occur in reality for break acctivation. |
