Sistem za sproten nadzor delovanja ekscentrične stiskalnice

V proizvodnih procesih je želja neprestano dosegati ustrezno kakovost in pravočasnost pri izdelavi izdelkov, ter s tem zadovoljiti želje kupcev. Težave se začnejo pojavljati, ko v starejših proizvodnjah nimamo ustreznega nadzora nad procesom in se je potrebno soočati s problemi v procesu kot so: obraba, lomi orodja, padci kvalitete izdelka, nepravilne nastavitve stroja, nepravilnosti na izdelkih. Cilj diplomske naloge je posodobiti obstoječo starejšo ekscentrično stiskalnico z vpeljavo sodobnega nadzornega sistema in tako izboljšati potek proizvodnega procesa ter spremljanje kvalitete izdelkov. V prvem delu smo obravnavali stiskalnico in ugotavljali glavne procesne parametre in variabilnosti pri zagotavljanju kakovosti v procesu preoblikovanja pločevine. Nato smo izbrali nadzorni sistem, ki spremlja in zaznava želene parametre ter na stiskalnico vgradili potrebne komponente za delovanje sistema. Po uspešni vgradnji smo sistem preizkusili in spremljali ter zaznavali napake v procesu. V rezultatih smo prikazali nekaj uspešno zaznanih napak ter opisali pridobitve v procesu z vpeljavo sistema. Zaključili smo z diskusijo pridobljenih rezultatov. In production processes, we constantly strive to achieve quality and punctuality in product production and, with that, fulfilling customers’ wishes. However, troubles start appearing when we have no appropriate process monitoring system in older productions, and we have to face problems in the process, such as wear, breaking of the tool, drop in product quality, incorrect machine settings, and product irregularities. This thesis aims to update an existing older eccentric press by introducing a modern monitoring system. In the first part, we evaluated the press and determined the principal process parameters and variability in quality assurance in the process of metal forming. Then we chose a monitoring system that follows and detects wanted parameters and installed the necessary components for the system to work onto the press. After a successful installation, we tested, monitored, and detected the faults in the process. In the results, we explained some of the successfully detected faults and described the gains in the process through the introduction of the system. Finally, the work is concluded with a discussion of obtained results.
