20.500.12556/RUL-171890 Konstruiranje matrice za upogibanje pločevinastih korit tračnega elevatorja Design of a die for bending sheet metal troughs of belt elevator Namen diplomskega dela je bil izdelava orodja za upogibanje pločevine, namenjene koritom tračnega elevatorja. V okviru dela sta bili najprej izdelani dve poskusni matrici s kotom 90 $^°$, ena z manjšim radijem, druga pa z radijem, približno enakim želenemu končnemu radiju upognjene pločevine. Namen teh matric je bil pridobiti začetne eksperimentalne podatke, s katerimi smo lahko določili faktor elastične izravnave K za pločevino S355JOWP. Ugotovili smo, da velikost radija upogiba znatno vpliva na vrednost faktorja elastične izravnave. S tem razlogom smo se z izdelavo druge lesene matrice poskusili približati končnemu radiju upogibane pločevine. Na podlagi izmerjenih kotov in radijev upognjenih vzorcev je bil določen povprečni faktor K (K$_α$ = 0,868). Ti podatki so nato služili kot osnova za izračun natančnega kota in radija končne kovinske matrice. Po izdelavi kovinske matrice so bile izvedene dodatne meritve na upognjenih surovcih, ki so pokazale minimalna odstopanja faktorja K (K$_{αp}$ = 0,870), kar potrjuje pravilnost začetnega eksperimentalnega pristopa. Tak pristop nam je omogočil zanesljivo dimenzioniranje končnega orodja. The purpose of this thesis was to design and manufacture a bending tool for sheet metal used in the production of troughs for a belt elevator. As part of the thesis, two initial wooden dies with a 90$^°$ angle were produced. One with a smaller bending radius and the other with a radius approximately equal to the desired final radius of the bent sheet metal. The aim of these dies was to obtain preliminary experimental data to determine the elastic compensation factor K for S355JOWP steel. It was found that the bending radius significantly affects the value of the elastic compensation factor. For this reason, a second wooden die was made with a radius closer to the target final bending radius. Based on the measured angles and radii of bent samples, an average K-factor was determined (K$_α$ = 0,868). This data served as the basis for calculating the precise angle and radius of the final metal die. After manufacturing the metal die, additional measurements were performed on the bent samples, which showed minimal deviation in the K-factor (K$_{αp}$ = 0,870), confirming the accuracy ofthe initial experimental approach. This method allowed for reliable dimensioning of the final tool. upogibanje pločevine orodje za upogibanje faktor K eksperimentalna analiza konstruiranje orodij sheet metal bending bending tool K-factor experimental analysis tool design true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-09-04 08:30:25 2025-09-04 08:30:29 2025-09-24 04:01:24 0000-00-00 00:00:00 2025 0 0 XXI, 47 str. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.7.072:621.981:519.6(043.2) 275356 248632067 43385.pdf 43385.pdf 1 AAB695483E5FEC0027E967E049031BDA cbcc1145904aab0856a24795e17135ff7abd4eaa44727da804cbb4f22f875acc 80fed781-8958-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=215456 Fakulteta za strojništvo 0 0 0
