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.

Roll bending technology
Hejna, Jaroslav ; Štroner, Marek (referee) ; Žák, Ladislav (advisor)
The paper deals with the research of sheet metal bending technology. This technology is suitable for producing both cylindrical and conical parts. First summarized technological and physical nature of the technology. Also important is the method of making cones using bending machines. Different types of machines are disassembled. From the smallest hand to the largest three-roll maschine. In the future, the two-cylinder machines are the most promising. They are especially suited to their variability and also because the component can be manufactured faster than any other machine.
