Abstract

Koosatud lõputöö baasettevõte on AS E-Profiil, mis seadis antud töö autorile eesmärgiks ettevõttes esmakordselt oleva toote masintöötluse tehnoloogilise protsessi väljatöötamise tellija poolt töösse antud seadmetele, vajaliku rakise projekteerimise ja tootmise omahinna arvutamise. Esmalt analüüsiti, milliseid pindu antud konstruktsioonis on vaja töödelda ning vastavalt sellele määratleti ära erinevate paigalduste arv. Valiti töötlemiseks vajaminevad instrumendid ning arvutati välja pingil tööks kuluv aeg. Teiseks võrreldi omavahel erinevate rakistuste konseptsioone, et konstruktsioon kinnitada töölauale. Valituks osutunud rakisele teostati tugevusarvutused 60 000 kg massi korral koos staatilisel koormusel nõutud ohuteguriga 1,2. Kolmandaks teostati majanduslikud arvutused sisetreipingile minevate kulude kohta aasta jooksul ning kahe käituri töötlemiseks minevad kulud. Lisadena koostati töötlusjoonised, rakise koostamiseks vajaminevad joonised, konstruktsiooni jaotusskeem, marsruutkaart, operatsioonikaardid ja paigaldusskeem.

Abstract [en]

The base company for this work is AS E-Profiil. Purpose of the work was to create machining technology, device to fix product on to machine table and calculate price for the production. At first was analyzed what kind surfaces needs to be machined, according to that were chosen how many instruments and placements are needed for machining and how long does it takes. Secondly fixing solutions were being compared to place the work piece to the machine table. Strength analysis was done for chosen fixing solution, where it was tested with 60 000 kg and safety factor was 1, 2 for a static stress situation. Thirdly came economical calculations where was calculated how much will cost whole year maintenance for horizontal milling machine and how much will cost to machine two propulsions. For annexes are presented machining drawings, fixing device drawings, product splitting for the workplace, operation charts and fixing scheme.
