Production of joint folded out the rule
Šoukal, Hynek ; Podaný, Kamil (referee) ; Žák, Ladislav (advisor)
Project developed within the bachelor study presents a proposal production technology of joint folded out the rule from construction steel 12 060. Thick is 0,5 mm and the production ran is specify at 30 000 units a year. In accordance with literature studies and by calculations have been designed a combined roll forming tool, which consists of a rack with two pillars. This tool will be fix in on eccentric press LEN 10C by SMERAL, Trnava, with nominal press force 100 kN. Trimming punches, holding punch and bending puch are made of tool steel, grade 19 436.3. Lower functional part of the tool ass well.

Optimization of a part production made of a structural 20 mm thick steel using laser cutting technology
Šoukal, Hynek ; Hála, Michal (referee) ; Mrňa, Libor (advisor)
The thesis deals with the optimization of process parameters in the oxidative laser cutting of structural 20 mm thick steel with regard to the type of material, the resulting roughness of the cut and the resulting price of the product. In line with the literary study and the Taguchi method, an experiment was developed. The cutting speed, laser performance, cutting gas pressure, and focal position were controlled during the experiment. Sample sets were cut with 7.5" and 10" focusing lens from the TATA STEEL S355MC and SSAB LASER 355 MC steels. According to ČSN EN ISO 9013, the samples were evaluated for roughness. Then micro and macro structures were evaluated, and compare the hardness according to Vickers. In conclusion, technical and economic evaluation was determined.
