20.500.12556/RUL-81661 Nadgradnja stroja za krivljenje cevi Upgrade of pipe bending machine Starejši CNC krmilniki so postali premalo zanesljivi za uporabo v industrijskih okoljih, kjer so vedno pomembnejši hitrost, zanesljivost in zmožnost hitrega odpravljanja napak. Zaradi tega se podjetja odločajo za zamenjavo celotnih strojev ali v primeru, da so le-ti mehansko še dovolj dobri, za njihovo nadgradnjo, saj to navadno predstavlja manjšo finančno investicijo. Diplomska naloga opisuje nadgradnjo stroja za krivljenje cevi italijanskega proizvajalca BLM Plauno. Glavni namen je bila zamenjava orginalnega Bosch CNC krmilnika s krmilnikom Siemens Sinumerik 828D. Izdelana je bila nova elektro omara, saj so bili zaradi združljivosti s krmilnikom zamenjani tudi pogoni osi in ostala elektro oprema. Za stroj je bil napisan nov program na PLK, določeni so bili parametri za optimizirano delovanje pogonov osi in izdelan je bil uporabniški program v G-kodi, glede na katerega stroj oblikuje cev. Ob predelavi je bilo poleg zahtev naročnika potrebno upoštevati tudi slovenske ter evropske pravilnike in standarde. Older CNC controls have become insufficiently reliabile for use in industrial environments, where speed, reliability and the ability of rapid troubleshooting is more and more important. For that reason the companies have been deciding to replace the machines or, if they are mechanically still good enough, to upgrade them since this represents a smaller financial investment. This bachelor thesis describes the upgrade of a tube bending machine, manufactured by BLM Plauno from Italy. The main purpose of the upgrade was the replacement of the original Bosch CNC controller with the Siemens Sinumerik 828D controller. Since axes drives and other electrical equipement were also replaced, a new electrical cabinet was designed to provide compatibility of the components with the controller. A new PLC program was made, parameters for optimized axes operation were set and a user program in G-code, according to which tubes are bent, was created. During the upgrade Slovenian and European regulations and standards had to be considered beside the customer's requirements. nadgradnja krivilnega stroja Siemens Sinumerik 828D numerično vodenje regulacija osi analogno regulirana os programirljiv logični krmilnik PROFINET DRIVE-CLiQ evropske direktive varnost stroja bending machine upgrade Siemens Sinumerik 828D numerical control axes control analogue axis control programmable logic controller PROFINET DRIVE-CLiQ european directives machinery safety true false false Slovenski jezik Angleški jezik Diplomsko delo 2016-04-25 14:50:01 2016-04-25 14:50:04 2022-08-01 22:18:08 0000-00-00 00:00:00 2016 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 34678 Kovacic_Urban_-_Nadgradnja_stroja_za_krivljenje_cevi.pdf Kovacic_Urban_-_Nadgradnja_stroja_za_krivljenje_cevi.pdf 1 243573DAE8B0592CB1E0C6CFDD82A41C 40a56fdd90f57993988346343fd8aecf6add515992ac6c265bda621037d5421e 708122c5-a1ad-11eb-a523-00155dcfd717 20.500.12556/rul/31cc0c64-7906-4e49-9c08-ab46b12f298b https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=81875 Fakulteta za elektrotehniko 0 0 0
