    Konštrukčná úprava strižných hrán
    (University of Žilina, 2024) Moravec, Ján
    The contribution is devoted to geometrical questions related to the issue of adjusting the active parts of the cutting tool. There are three modifications of the cutters: With the blade beveled inward and bevelled outward, the blades formed by the intersection of two cylinders. The necessary schemes of these solutions and the necessary mathematical relations are published.

    Klinové zváranie rúrok
    (University of Žilina, 2024) Moravec, Ján
    The article points out the possibilities offered by wedge welding, that is, one that does not require classic additional material and the creation of a welded joint. two significant methods of joining pipes are pointed out and the advantages of this neglected method of joining different materials of different chemical composition are also mentioned.

    Magnetic forming with heat in a magnetic field
    (University of Žilina, 2024) Moravec, Ján
    The article focuses on the application of a magnetic field in the forming of low-carbon steel castings. The original solution of the forming device, which was used in the experimental works, is presented. The results of the experimental works confirmed the suitability of its use for the mentioned work.

    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.

    Tvárnenie v hydraulickom prostredí explóziou
    (University of Žilina, 2023) Moravec, Ján
    The article describes and analyses the issue of explosive sheet metal forming in a hydro environment. In the introductory part, the necessary theoretical and technological knowledge is presented, which is necessary as a theoretical introduction to the issue. The explosion process in a liquid environment is described. The reflection from the surface and bottom of the tank used in the experiment is important. The paper only offers a view of the theoretical side of the process, because the legislative framework does not yet allow direct experimental work to be carried out, which must be done by a certified specialist in the handling of explosives.

    Uzatváranie koncov rúr v tvarovej lisovnici
    (University of Žilina, 2023) Moravec, Ján
    The paper describes the issue of closing pipe ends in a pressing tool specially designed for this work. Theoretical relations from the theory of forming form the necessary basis for the subsequent design of the tool. production process. A simple tool with the application and consideration of theoretical knowledge usually brings a significant effect expressed not only financially, but also qualitatively, which was also confirmed in this case.
