20.500.12556/DKUM-90115 Dimenzioniranje premične čeljusti primeža za stiskalnico "Rotopress" diplomsko delo Design of the movable clamp jaw for the "Rotopress" press V diplomskem delu je predstavljen postopek dimenzioniranja premične čeljusti primeža stiskalnice »Rotopress« za podjetje Ledinek Engineering d.o.o. Pri samem dimenzioniranju smo upoštevali, da je potrebno ohraniti vse pritrdilne površine, čeljust se ne sme plastično deformirati pri maksimalni delovni sili, ki znaša 200 kN, in pa sama konstrukcija mora biti enostavna za varjenje. Predstavili smo tri variante premične čeljusti in jih primerjali s staro verzijo, katere maksimalna delovna sila je bila 140 kN. Cilj je bil, da je na novi verziji premične čeljusti napram stari verziji zmanjšana masa konstrukcije, zmanjšana maksimalna napetost in pa pomik ne sme biti večji od 1 mm. Za potrebe varjenja smo določili tehnologijo varjenja in katere pozicije na konstrukciji je potrebno predhodno predgrevati. Izdelali smo tudi tehnično dokumentacijo. The thesis presents the procedure for dimensioning the movable jaw of the "Rotopress" press vise for the company Ledinek Engineering d.o.o. In the dimensioning process, we took into account that all mounting surfaces need to be preserved, the jaw must not undergo plastic deformation at the maximum working force of 200 kN, and the structure itself must be easy to weld. We presented three variants of the movable jaw and compared them with the old version, whose maximum working force was 140 kN. The goal was to reduce the mass of the structure, decrease the maximum stress, and ensure that the displacement does not exceed 1 mm in the new version of the movable jaw compared to the old version. For welding purposes, we determined the welding technology and which positions on the structure need to be preheated. We also created the technical documentation. dimenzioniranje premična čeljust lameliran lepljen les MKE varjenje dimensioning movable jaw glued laminated timber FEM welding true true false [N.
