| Sažetak | U teorijskome dijelu diplomskog rada objašnjen je sami postupak tehnološke operacije bušenja. Zatim slijedi općeniti opis naprava, njihova podjela i osnovni zadatak naprava. Objašnjena je upotreba naprava za bušenje, kakva im mora biti konstrukcija, te kako se dijele prema oblikovanju naprave. Slijedi upoznavanje konstrukcije elemenata naprave za bušenje, elemenata za određivanje položaja, načina stezanja, centriranja te fiksiranje i vođenje alata. Objašnjena je primjena tripleks bušilice, navedene glavne specifikacije i sastavni dijelovi, te čemu služi i kako se održava stroj na dnevnoj bazi. Drugi dio i glavna tema ovog rada je projektirati tehnološki proces izrade naprave za bušenje.
U radu je konstruirana i izrađena naprava za bušenje fazonskih T-komada na tripleks bušilici. Konstrukcija je izvedena na način da može fiksirati komade različitih duljina i promjera od DN50 do DN200. Prije same izrade konstrukcije, prikazano je mjerenje postolja stroja mjernom rukom za prilagodbu stola. Za prikaz rješenja naprave izrađen je 3D model u programskom paketu SolidEdge, pomoću kojeg je izrađena i tehnička dokumentacija. Nakon toga pristupa se tehnološkoj razradi izrade pojedinih pozicija naprave, od operacije rezanja materijala i zavarivanja pozicije do same strojne obrade. Opisani je postupak izrade CNC programa i izbor alata u programskome alatu SolidCam, te prikazana obrada na obradnome centru. Izrađene su upute za pripremu tripleks bušilice, te upute za rad koje služe za lakše rukovanje strojem, od uzimanja nul točki do korekcije programa.
Nakon svih ovih realiziranih procesa do konačne svrhe izrade naprave za bušenje, a to je obrada komada, prikazana je izrada mjernog protokola za provjeru važnijih dimenzija upotrebom mjerne ruke. |
| Sažetak (engleski) | In the theoretical part, the procedure of the technological drilling operation itself is explained. Then in general about the devices, the division and the basic task of the device. The use of the drilling device is explained, what their construction must be, and how they are divided according to the design of the device. Getting to know the constructions of the elements of the drilling device, which are the elements for determining the position, methods of clamping, centering, fixing, guiding the tool. The application of the triplex drill machine is explained, what are its main specifications and main parts, what they are for and how to maintain the machine on a daily basis.
The second part and the main topic of this work is to design the technological process of making a drilling device.
In the work, a device for drilling shaped T-pieces on a triplex drill was designed and made. The construction is made in such a way that pieces of different lengths and diameters from DN50 to DN200 can be fixed. Before the construction itself, the measurement of the machine base with a measuring arm for adjusting the table is shown. To display the solution, a 3D model was created in the SolidEdge software package, with which the technical documentation was also created. After that, the technological development of making individual positions of the device is approached, from the operations of cutting materials and welding positions to the machining itself. The process of creating a CNC program and the choice of tools in the SolidCam program tool are described, as well as the display of processing on the machining center. Instructions for the preparation of the triplex drill machine were created, as well as operating instructions for easier handling of the machine, from downloading the zero point to the correction program.
After all these realized processes, for the purpose of making a drilling device, which is the processing of pieces, the creation of a measuring protocol for checking the necessary dimensions using a measuring arm is presented. |
