STAMPING TOOL CONSTRUCTION FOR PRODUCT PD_TS_2019

Štancanje kao tehnika obrade materijala koristi se stoljećima, a postoje i dokazi koji upućuju na to da je i pračovjek koristio štancanje kako bi si olakšao neke radnje. Štancanje je napredovalo kroz stoljeća pa se u 19. stoljeću pojavljuju kompliciraniji alati u postolarskoj industriji. U današnje vrijeme, štancanje ima vrlo važnu ulogu u obradi materijala. Alati postaju sve složeniji i kompliciraniji, a izradci su sve bolji i precizniji. Prvo poglavlje rada sadrži uvod u sam rad i uvod u štancanje. Teme koje će biti obrađene opisivat će načine štancanja, podjelu štanci i ostale opće informacije vezane uz samu tehniku štancanja. U drugom poglavlju vršit će se proračun iskorištenja materijala koji je jedan od glavnih pokazatelja isplati li se obrada uopće vršiti ovim postupkom. Treće poglavlje sadrži proračun sila, momenata, naprezanja i deformacija. To su najvažniji proračuni koji će odrediti konstrukciju alata. Četvrto će poglavlje opisati konstrukciju alata kroz proračun dimenzija ploča, žiga i matrice kako bi se prema dobivenim vrijednostima mogao konstruirati efektivan alat. Peto poglavlje bit će zaključak i osvrt na rad.Die-pressing as a way of processing materials is being used for centuries. There are even evidence which suggest that the first-men used die-pressing as a mean to make their lifes easier. Die-pressing made a progress throughout centuries and in the 19th century the tools for die-pressing are becoming more complex and are being used by shoemakers. In today's world, die-pressing plays an important role in processing materials. Stamping tools are more complex and final products are better and more precise. The first chapter is a general introduction to this paper and into general die-pressing. It will cover different ways of pressing and stamping, classification of different stamps and general information about the process itself. Second chapter consists of calculation of the waste made by die-pressing. This is one of main indicators whether the right aproach to make the final product was chosen. Third chapter is calculation of needed force, moments of exertion, strains and deformations. Those calculations are the ones that will determine the design of the die-pressing tool. Forth chapter will describe the design of the tool throughout the calculation of segments of the tool. Fifth chapter is a the final conclusion and review of the whole paper
