FORGING DIE CONSTRUCTION FOR PRODUCTION OF CV JOINT OUTER SHELL D_FR_2019

U uvodnom dijelu ovoga rada dan je kratak opis teorije oblikovanja metala deformiranjem s osnovnim podjelama, te je opisan razvoj tehnologije kovanja kroz povijest i postotak primjene navedene tehnologije u vodećim svjetskim i europskim zemljama u proizvodnji otkivaka. Tehnologija kovanja u drugom dijelu rada je podijeljena na slobodno kovanje i kovanje u ukovnjima te je dan detaljan opis navedenih postupaka uz glavne prednosti i nedostatke. Također opisana su i navedena sva pravila i najvažniji procesi o kojima je potrebno voditi računa prilikom proračuna i konstrukcije otkivka koji je u ovom slučaju kućište homokinetičkog zgloba. Na kraju u zadnjem teorijskom dijelu ovoga rada navedeni su i opisani kovački strojevi i peči koji se mogu koristiti za izradu odnosno predgrijavanje navedenog otkivka. U posljednjem dijelu ovoga rada izvršen je proračun potrebnih gravura, stroja za kovanje, dimenzija ukovnja i ostalih potrebnih podataka, te je na osnovu njih izvršena konstrukcija alata za kovanje sa svim pripadajućim dijelovima.In the introductory part of this work, a short description was given about a theory of forging steel using a deforming technique with it’s basic classification. This part also describes the development of the forging technique through history and the percentage of implementing these techniques in leading global and European countries in manufacturing forged steel. Technology of forging steel in the second part of this work is separated on free forging and die forging and a detailed description of these procedures is given with it’s main advantages and disadvantages. Likewise, all rules and most important processes are described which should be taken into account during the calculation and construction of forged product, which in this case is the housing of the homokinetic joint. In the last theoretical part of this work forging machines and ovens are mentioned and described which can be used to make or preheat the aforementioned forged steel. In the final part of this work, the calculation of the required gravure, forging machine, dimensions of the forging die and other necessary data was made and based on them the construction of a forging tool with all of it’s associated parts was carried out
