20.500.12556/DKUM-20666 RAZVOJ POTISNEGA ČEVLJA IN DOLOČITEV MEJNE NOSILNOSTI DEVELOPING OF THE PRESS SHOE AND LIMIT LOAD ANALYSIS Ledinek Engineering d.o.o., za katerega sem opravljal diplomsko delo, izdeluje predvsem stroje in proizvodne linije za obdelavo lesa. Diplomsko delo zajema postopek razvoja novega potisnega čevlja, ki je bil razvit v sodelovanju s Fakulteto za strojništvo Maribor. Primarni cilj razvoja je bil predvsem zmanjšanje teže potisnega čevlja ob zahtevani nespremenjeni nosilnosti stiskalnice Hyperpress, namenjene avtomatizirani izdelavi ukrivljenih lepljenih elementov, za približno 40%, kar nam je tudi uspelo. V diplomi so zajeta najpomembnejša področja razvoja novega, lažjega potisnega čevlja, od razvoja nove oblike do priprav na proizvodni proces, ki zajema razrez, pripravo, sestavo in varjenje potisnih čevljev. Velik poudarek je ravno na varjenju potisnih čevljev, saj so se pojavile neugodne zaostale napetosti in z njimi povezane deformacije, zaradi katerih je bilo potrebno razviti celoten tehnološki proces izdelave potisnih čevljev. The company Ledinek Engineering d.o.o., for which this thesis has been carried out, mainly produces woodworking machines and production lines. The thesis includes a description of the development of a new push shoe, which was developed in collaboration with the Faculty of mechanical engineering Maribor. The primary objective of development was to reduce weight of the push shoe for about 40%. The push shoe is part of the Hyperpress press, which is designed for fully automated production of curved laminated beams. The thesis covers the most important areas of the development process of a new, lighter push shoe, such as computer modeling, optimization and preparations for the production process, which includes cutting, preparation, assembly, and welding processes. Especially welding represents one of the main areas in the thesis because of residual stresses and associated deformations, which made it necessary to develop a complete new technological process of push shoe production. konstruiranje optimizacija lameliran lepljen les potisni čevelj metoda končnih elementov varjenje zaostale napetosti mejna nosilnost mechanical design optimization glued laminated timber press shoe finite element method welding residual stress limit load true true false [G.
