20.500.12556/DKUM-20868 IZDELAVA VZMETI D3,2 ETB2-6 3S S POSTOPKI PREOBLIKOVANJA MANUFACTURE OF SPRING D3,2 ETB2-6 3S WITH THE FORMING PROCESS Pomembno vlogo v proizvodnem procesu izdelave tečajev, za vgradnjo v štedilnike in vgradne pečice ima natezna vzmet, brez katere tečaj ne more pravilno delovati. Jeklena vzmet je elastični element, ki je sposoben pod vplivom zunanje obremenitve sprejeti delo in ga po potrebi vrniti v obliki potencialne energije. Navidezno gre za zelo preprost in transparenten izdelek, v ozadju katerega, pa je praktično znanje, ki je poznano osebam, ki se ukvarjajo s proizvodnjo vzmeti, poleg tega pa pri proizvodnji ustvarja stroške, ki jih ni mogoče enostavno upravljati. V diplomski nalogi sem predstavil stroje za obdelovanje in preoblikovanje vzmeti. Stroj je mehanična naprava, ki prenaša ali pretvarja energijo in s tem omogoča, olajšuje ali opravlja delo. Sestavljen je iz več mirujočih in gibajočih se delov. Vzmet sem narisal s 3D programskim paketom in nato obremenjeval v temu primernim programu za simuliranje, kateri je prikazal kritične točke vzmeti. Podal sem tudi analitične izračune, katerih rezultate sem imel v postopku preoblikovanja za robne pogoje. Natezno vzmet sem optimalno preoblikoval in ji s tem podaljšal življenjsko dobo. Important role in the production process of manufactoring courses, for installation in stoves and ovens have built-in tension spring, without which the course can not work properly. Steel spring is an elastic element, whose is capable to accept given work under the influence of external loads, and give it back as an potential energy. Apparently, it is a very simple and transparent product, in the background of which, is however , a complex »know-how«, known to the spring manufacturers, in addition, the production creates costs that can not be easily managed. In the tesis i presented the machines, who process and transform springs. The machine is a mechanical device, that transfers or converts energy, thus enabling, facilitating or carrying out work. It consists of several stationary and moving parts. I drew a spring with a 3D software package, and then imputed it in program suitable for simulations, whose showed me weak spots of the spring. I gave the analytical calculations, whose results, I had in the process of transformation for the boundary conditions. I optimized and transformed the spring, to achieve longer life work. vzmet upogibanje predelava izdelava preoblikovanje MKE proizvodnja spring bending processing production transformation FEM manufacturing true true false [M.
