20.500.12556/DKUM-43185 Uporaba servo pogonov v stiskalnicah z omejeno potjo The usage of servo drives in mechanical presses Tehnološko zahtevni izdelki zahtevajo razvoj naprednih preoblikovalnih postopkov, pri katerih je uporaba konvencionalnih mehanskih stiskalnic nemogoča. Z uporabo servo pogonov v stiskalnicah z omejeno potjo je možno slediti trendom razvoja. Diplomsko delo prikazuje temeljne karakteristike navadnih mehanskih stiskalnic in stiskalnic s servo pogoni. Pri razdelitvi stiskalnic glede na pogonski mehanizem, se diploma osredotoča na 3 najbolj značilne zasnove. Te so: ekscentrska, kolenasta in večzgibna zasnova. Namen naloge je izvesti podrobno primerjavo med kinematičnimi veličinami obeh konceptov stiskalnic in v kakšni meri te veličine vplivajo na preoblikovalni proces. Z uporabo servo pogonov zagotovimo neposreden nadzor nad celotnim hitrostnim profilom stiskalnice, neodvisno od položaja paha, kar s pridom izkoriščamo za izboljšanje produktivnosti in zagotavljanje kakovosti. Technologically demanding products demand the development of advanced forming processes in which the usage of conventional mechanical presses is not possible. The usage of servo drives in stroke controlled presses allows these trends to be followed. The diploma work shows the fundamental characteristics of ordinary mechanical presses and presses with servo drives. Splitting the presses based on their drive mechanism, the diploma focuses on the 3 most typical designs. These are: eccentric, knuckle-joint and link-drive design. The purpose of the diploma work is to make a detailed comparison between the kinematical values of both press concepts and the effect these values have on the forming process. The usage of servo drives grants us direct control over the whole speed profile of the press, independent of the slide position, which we exploit to improve productivity and quality assurance.
