Manufactory of drown flanges on a sheet of high-strength steel
Laštovica, Petr ; Vašík, Ladislav (referee) ; Lidmila, Zdeněk (advisor)
Based on study of documents supplied by PWO Unitools a.s. and on advices of design office staff, tool for forming flanges was designed. This tool was then manufactured and it has been used for carrying test of creating flanges of various diameters from high-strength steels. During these tests, the following parameters were optimized – force of upper and lower blank holder and the height of the main guides. Threads were created into these drown flanges. These threaded joins were later tested for maximum torque and maximum compressive strength.

Moderní výroba kovových dílů používaných v dopravní technice
KOUBA, Matěj
In all branches of human activity there is a certain advance and the development of modern materials and new technological processes in production. This work summarizes this procedure, especially in the field of transport technology. However, conventional production is an important part of modern production, that is why the work is divided into two parts. The first part deals with the conventional production of metal parts, especially materials such as steel and aluminum and conventional methods of forming body parts. The second part provides information on the first, second and third generation of AHSS steels and modern production technologies that have the potential for use in transportation technology. Conventional methods are mainly drawing and pressing. Modern methods in the production of metal parts can be hydroforming, high-speed forming. In recent years, additive production has become very popular, especially 3D printing.
