Steiner, Jaromír ; Varjan, Matúš (referee) ; Žák, Ladislav (advisor)
The main topic of this thesis is the fineblanking technology with a vee-ring which was chosen as the most suitable solution. The aim is a design and an assessment of technologicity of the selected component, a draft of the structural design of the tool and an economic evalua-tion of the project. The chain wheel has been designed from structural steel 11500; parameters have been evaluated as appropriate. The instrument has been designed as two-station progressive tool for single-row layout of the fineblanked parts with a moving punch; the vee-ring is positioned both to the blanking plate and to the vee-ring plate. The press was chosen on the basis of the calculated shearing force by Feintool Company. At the selected batch 500,000 units, 5.1 CZK per fineblanket part has been calculated.
