Production of the gutter hook
Šobáň, Jakub ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
This bachelor thesis introduces a gutter hook technology production design made of 5 mm thick 11 321 steel sheet. Progressive die tool shearing and bending was chosen as the best production technology. Technology and structure calculations were done for this method. A three step hole punching bender tool has been designed. HMG 100 press produced by TVARtech company – stroje s.r.o. with a coil feeding line by Coiltech company was chosen for production in accordance with the power requirements.

Manufacturing of fitting door
Rosenbergová, Lucie ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This bachelor thesis is focused on the design of the technology of the production of the locks lock plate. The component is made from 11 321 steel in form of scroll with 1,5mm width. Produciton series is 35,000 pcs/year. From the considered procution technologies is cutting and bending in progressive die tool the best. After determining the dimensions of the developed shape was suitable technological proces chosen. Acording to that is desired shape achived in four steps.Based on the performed calculation was combined tool constructed. Component will be manufactured at the eccentric press S 160 E from Šmeral Brno a.s. This press satisfies with dimensions of the tool and also with necessary forming force. The sale price is 20,4 Kč with 70%profit included. Production becomes profitable after exceeding 16 054 pieces.

Production hinge saddle motorcycle
Hanych, Libor ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The project elaborates the design of technology production of the hinge used for fixing saddle motorcycle. The hinge is manufactured from 1 mm thick construction sheet steel 1.0038 in production run of 50 000 pcs/year. A technology of shearing and bending at progressive die tool was selected from various options as the most suitable technology of manufacturing. Based on the literature study of shearing and bending technology, an optimal production process of hinge was designed. After technological, structural and control calculations the tool was designed and the technical documentation was elaborated. The eccentric press LKDR 200 made by ŽĎAS company was selected for the production. This press complies in terms of required forming force and the dimensions of the tool. Using the economic evaluation, the production costs for one hinge were calculated in the amount of 18,5 CZK. 35% profit of the company is included in the price. According to the calculated turning point, the production becomes profitable after 24 187 piece being manufactured.
