Design of Tool for Louvers Production
Hejna, Jaroslav ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
This thesis presents a tool design for production of embossments into the bottom part of the agricultural silo made of Dx51D material. The research analysis all technologies used for embossing, that is cutting and shallow drawing. This is followed by a chapter on simulation. The tool design itself is described. Its principle is based on tools for punching machines. The upper half of the tool is composed of a weldment to be clamped into pressing machine, into which are mounted functional parts in the form of inserts. The lower tool consists of several bolted plates, punches and a holding plate, which is located on the springs. In order to achieve correct design, necessary calculations were carried out and it was all confirmed by simulation in ANSYS. The two tool halfs are guided by pins attached at the edges of the lower tool. The technical - economical evaluation compares the work of the proposed tool with other possibilities of embossing.

Production single parts from sheet metal
Nutilová, Marcela ; Peterková, Eva (referee) ; Žák, Ladislav (advisor)
The project drawn up within the framework of engineering studies in discipline Manufacturing technology (2303T002) presents a proposal for processing a single part – the part is made of sheet steel number S420MC – by blanking, bending and stamping. On the basis of a literary exploration of given problems several variants of processing a part was propounded in order to be made in just one tool. The transfer combined die is fixed in crank press WAINGARTEN ARP 80 with 800 kN nominal force. All functional parts are made of heat treated tool steel number 19 573.3 according to drawing documentation. Lower functional parts of tool (blanking die, stamping die and bending tool) are made as divided.
