Forging can be defined as a technology of metal forming through hammering, usually in a heated state. It is categorized by open and closed forging. Closed die forging, also known as impression forging, is more significant for this master thesis. The forging die is precisely constructed tool which consists of two halves. The shape and dimensions of the workpiece are given by the impressions that were engraved in dies by machining. Forged parts are characterized by excellent mechanical properties, especially strength, which is a result of aligned grain flow of metal, and for this reason, elements exposed to frequent impact loads are mostly forged. Technology of forging is being compared to other production technologies such as machining, casting, welding, powder metallurgy and additive technologies. Then the tool calculation and construction for tractor steering arm forging, according to technical drawing D_FA_2023/2024, were created. Calculation includes the determination of tolerances, machining allowances, forging chamfers, fillets, flash and punching slug. All the necessary impressions and external dimensions of the forging die were constructed, and finally forging machine that is powerful enough was chosen. In the end, a 3D model of the forging die and its technical documentation were created by usage of the Autodesk Inventor Professional 2023 and AutoCAD 2023 software packages, which can be found in the attachments of this master thesis.
