Proposal of production technology of uni-axial rod
Zejda, Václav ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The thesis is focused on the proposal of production of a stamped part of the uni-axial rod located in the axle of the truck. The uni-axial rod is made of materiál S420MC with thicknes of 4 mm and the planned series production is 84 000 pieces per year for 7 years. The most difficult point for production is a collar, which create support of the bushing. It is not posibble to produce a required height with conventional one-stage process, which was experimentally verified. In the programm PAM-STAMP there was designed multiple-stage process of the production with the use of numerical simulation. The progressive die was designed for this process of the production. Maximal load of a forming press is 5 057 kN. Production will be located on the forming press Kaiser 8000-50-F5-RKM by ANDRITZ Metals. Maximum force of the forming press is 8 000 kN.

Manufacturing of backstop
Toufar, Jan ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
Thesis solves the design of manufacturing technology of steel backstop – the part made by shearing and bending. The component will be made from a rolled steel coil of the DC01+ZE25/25-A-P-C material with the thickness of 1 mm. The batch size is determined 200 000 parts per year. At base of choosen process and calculations is designed progressive die for shearing and bending. Shearing punches, punching dies, bending punch and dies are made from steel 19 436. Die is made for eccentric press LENR 25-A with forming force 250 kN.

Manufacturing of slider
Chládek, Martin ; Havliš, Stanislav (referee) ; Podaný, Kamil (advisor)
Slider is a part of turn restrictor mechanism designed by company TOKOZ a.s. It is a part with complicated form and small dimensions from material DC04 (equivalent according to Czech standard ČSN 11 305.21). As the most suitable option for part manufacturing was chosen cutting and bending in progressive die. A design of forming layout with 11 stations was made and considering the outcomes of related calculations preliminarily selected presses LEXN 100 and Kaiser KSTU 1600. Subsequently was designed one row progressive die. Based on this designs were made few variants of part price calculations according to TOKOZ company customs. According to price calculation outcomes was as the most suitable selected press Kaiser KSTU 1600.

Sheet metal forming production of automobile frame top
Marák, Daniel ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The project, which have been created within the framework study of engineering branch N2326, submit project technology process of pressing - part from micro-alloyed steel with higher yield point H 240 LA and proposal of tool design for its pressing. Technology process was designed in ten operations, base on literary studying of cold forming technology. Design of progressive die respects type of press machine, which is specified for production this part. Press KRUPP 400t disposes pressing force 4 000kN. Materials, used for design of tool, are in use by tool shops. Punches and punching dies are produced from steels 19 573, heat-treated according drawing documentation. Drawing punches and dies are produced from steel 19 552, hardened on 56+2HRc and coated by TiCN method.

Manufacture of car lock components
Andris, Tomáš ; Císařová, Michaela (referee) ; Lidmila, Zdeněk (advisor)
The thesis is focused on the proposal of manufacturing technology of the opening lever for a car latch. The lever is made of S355MC sheet metal with thickness 2 mm, production series is set for 400 000 pieces per year, which includes 200 000 pieces of right and 200 000 pieces of left version. After considering several production methods, combined progressive die was chosen. The part is made in ten steps, which include shearing and bending. Necessary technological, design and safety calculations were also made. For production was chosen eccentric press S160 made by ŠMERAL company. Surface protection of the part will be provided by galvanizing. At the end of the thesis a technical and economical evaluation is provided. The final price of one piece of lever is calculated to 13,3 Kč, economical turning point when production become profitable was calculated to 156 339 pieces.
