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.

Typical features of progressive shearing
Žanda, Jakub ; Harant, Martin (referee) ; Štroner, Marek (advisor)
The bachelor thesis first covers the basic theory of shearing technology, its process and the quality of the shearing surface. Then it focuses on the technology of progressive shearing. Its advantages and disadvantages are thoroughly described, and furthermore it is compared with other shearing methods in cutting dies. This is followed by a description of the individual components of the die and an explanation of their function and use. The material requirements of the tools are discussed and their heat treatment is presented. The last part is focused on the evaluation and contribution of this technology.
