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.

Tube bending
Richter, Tomáš ; Peterková, Eva (referee) ; Žák, Ladislav (advisor)
The bachelor thesis deals with the theoretical analysis technologies of bending circular cross-sections. In the first part are said formulas for the calculation of the processes occurring in the blank material and formulas to refine the viability of the operation (or for the assessment of defects). The second part describes the current technologies used for bending pipes of circular (and other) cross-sections.
