Production of plough share screw
Hladík, Milan ; Jopek, Miroslav (referee) ; Forejt, Milan (advisor)
The bachelor's thesis presents a design of plow screw production technology used to attach the blade to the plow frame. The screw is made of structural steel 14,140, in a production series of 120,000 pcs / year. From the possible technologies, the technology of volume cold forming was chosen. From the literature sources of the issue of volume cold forming, the optimal procedure of screw production was proposed. With the help of design, technological and control calculations, a machine was designed and subsequently a production tool, for which drawing documentation was prepared. With the help of technical - economic evaluation, the costs of component production were compared using volume forming and machining.

Housing production by cold forming
Kouřil, Jakub ; Kunčická, Lenka (referee) ; Jopek, Miroslav (advisor)
The bachelor thesis is focused on the production of a part by cold forming. The subject of the thesis is the design of the technology of production of a housing with a production rate of 6 000 000 pcs/year by extrusion and tamping. The austenitic stainless steel X5CrNi18-10 is used for the production. Based on simulations, the most suitable geometric configuration of the forming operations was selected. The whole production process consists of a first cutting, two forming and a last machining and radnishing operation. Based on the calculated forming force of 175,6 kN and the required power of 425 W, the CHUN ZU CBF-83S automatic forming machine was selected. At the same time, the tool is designed and in the end a techno-economic evaluation is carried out, which also includes the calculation of the piece price considering a 15% profit, which amounts to 1,24 CZK.
