CALCULATION AND CONSTRUCTION OF STAMPING AND BENDING COMBINED TOOL FOR PRODUCT GIVER BY TECHNICAL DRAWING PR_2018_FG

Tema ovog diplomskog rada je proračun i konstrukcija kombiniranog alata koji istovremeno vrši proces prosijecanja, probijanja, savijanja i odsijecanja. Ovdje je prikazan i detaljno objašnjen postupak proračuna i konstruiranja svih alata koji su spojeni u jednu cjelinu, te tako obavljaju svoju funkciju. Na osnovu rezultata dobivenih proračunima sila i naprezanja provodi se konstrukcija i dimenzioniranje kombiniranog alata za štancanje i savijanje koji se sastoji od više sastavnih dijelova. Za svaki dio postoji nekoliko konstrukcijskih izvedbi te je potrebno odabrati optimalnu. Sastavni dijelovi prikazani su crtežom, a bitno je izraditi što precizniji alat sa što manjim troškovima. Također, usporedbom mogućih tehnologija izrade zadanog komada objašnjeno je zašto se kombinirani alat isplati izraditi u odnosu na druge tehnologije.The aim of this graduate thesis is calculation and construction of a combined tool which simultaneously performs the process of slicing, punching, bending and cutting. Here, a detailed method is shown of calculation and construction all the tool elements that will be connected to one unit at a later time. Based on the results of the calculations of force and stresses, the construction and dimensioning of the combined punching and bending tool consists of several components. For each part there are several constructional designs and it is necesary to make optimal choise. The components are shown in the drawing, and it is essential to make the most accurate tool with the lowest cost. Also, by comparing the possible technology of making a default piece, it is explained why the combo tool is worth making compared to other technologies
