Abstract

Servo hidravlične stiskalnice predstavljajo visoko-dinamične pozicionirne sisteme krmiljene s servo ventili, ki se uporabljajo za najzahtevnejše proizvodne procese in testne naprave. Od njih se zahteva visoka fleksibilnost, ob hkratni visoki dinamiki obratovanja ter visoki pozicijski ločljivosti. Za doseganje zgoraj naštetih karakteristik, ki so odvisne od uporabljenih mehanskih, hidravličnih in krmilnih komponent stiskalnic, smo v magistrskem delu podrobneje popisali in analizirali glavne vplivne parametre teh sistemov. V prvem delu naloge smo obravnavali teoretične osnove servo hidravličnih stiskalnic in njihovih komponent, krmiljenje in krmilne metode. V nadaljevanju smo zasnovali koncept hidravličnega krmilja za zaprto-zančno krmiljenje poti, tlaka in sile. Zasnovali smo ustrezno ogrodje stiskalnice in izvedli trdnostno analizo kritičnih komponent. Na podlagi koncepta smo izdelali simulacijski model in podrobneje analizirali vse glavne parametre, ki bistveno vplivajo na obnašanje hidravličnega sistema. Na podlagi koncepta hidravličnega krmilja in simulacijskega modela, smo izdelali prototip stiskalnice in izvedli zagon sistema. V okviru zagona sistema smo izvedli eksperimentalno analizo, pri kateri smo obravnavali cikel za proces globokega vleka in preverili delovanje merilne opreme.

Secondary abstract:	Servohydraulic presses represent highly dynamic positioning systems controlled by servovalves, which are widely used in demanding manufacturing processes and testing equipment. The mentioned systems can operate in highly dynamic manufacturing processes, and should be very flexible and precise. In order to achieve these characteristics, which depend on the mechanical and hydraulic components used and their control, the main system parameters were analyzed in detail. In the first part of the master thesis we gave an overview of the theoretical principles of servo-hydraulic presses, their components, type of control and control methods. Further, we created a concept of a hydraulic closed-loop position, pressure and force control system. A suitable press frame was designed and strength analysis was carried out for the critical components. A simulation model was created based on the input data and the main model parameters that have a significant effect on the behavior of the hydraulic system were analyzed in detail. Based on the hydraulic control concept and the simulation model, a press prototype was designed and a test run was performed. Finally, the experimental analysis was carried out, in which the typical cycle of the deep drawing process was investigated and the proper operation of the measuring equipment was tested.
