Rovnanie plechu bodovým ohrevom
(Žilinská univerzita v Žiline, 2023) Moravec, Ján
The contribution is devoted to the issue of material alignment. The theoretical description and essence of straightening by local heating is presented. Mechanical methods of leveling the material are also covered. In the experimental part, an experiment is described, which is based precisely on the theoretical analysis of the process of straightening by local heating.
Tvárnenie skla v jednoduchom tvárniacom nástroji
(Žilinská univerzita v Žiline, 2023) Moravec, Ján
The contribution presents the analysis and issues of glass forming in a forming tool with external heating. The necessary theoretical knowledge and properties of glass, which are necessary for solving the design of the forming tool, are listed. technological methods of glass forming are mainly press-blowing and forming with a double-blowing system. With the help of the described tool, glass can be relatively successfully shaped, which is inserted into the tool in the shape of a plate. The glass plate, which is bent into a cylindrical or hemispherical shape, is placed on the press and heated with a flame until the glass is sufficiently soft to work with.
