Prispevek k stabilizaciji procesa hladnega preoblikovanja žice = [Contribution to the stability of the cold forming process of wire] : doktorsko delo

Nastran, Miha

ǂV ǂdisertaciji je obravnavana problematika stabilnosti preoblikovalnih proizvodnih procesov predelave žičnatih materialov. Sodobni prijemi za regulacijo geometrijskih parametrov izdelka s ... spreminjanjem kinematike in geometrije orodja so nadgrajeni v smeri vplivanja na mehansko preoblikovalne lastnosti preoblikovanca. Teoretično ozadje dela predstavlja Bauschingerjev efekt, ki ga srečamo pri hladnem preoblikovanju žice. Dejstvo, da med ravnalnim proizvodnim procesom lahko vplivamo na napetost tečenja materiala v obeh smereh, s pridom izkoristimo in ga uporabimo kot regulacijsko jedro procesa. Najprej se lotimo analitičnega modeliranja ravnalnega procesa, kjer z uvedbo dodatnega parametra v reološkem modelu materiala, dodamo možnost spreminjanja meje tečenja materiala. Model v optimizacijskem algoritmu služi za izračun potrebnih geometrijskih sprememb v orodju. Merjenje preoblikovalnih sil nam skupaj z inverznim pristopom k določevanju materialnih karakteristik predstavlja osnovo za potrebne korekcije preoblikovalnih orodij. Model na koncu preizkusimo tudi na realnem velikoserijskem proizvodnem procesu.
