Item Hydraulický ráz a jeho aplikácie v tvárnení(University of Žilina, 2025) Moravec, JánThe presented paper discusses the issue of the possibility of forming metals using hydraulic shock. The first part of the text presents the necessary theoretical knowledge about the issue. The second part presents some solutions of this advanced metal forming technology.Item Združené voľné a zápustkové kovanie(University of Žilina, 2025) Moravec, JánThe article deals with the issue of metal processing by hot forming, in this case by forging. The text points out the supporting facts that influence the possibility of applying combined open and drop forging. This technology will become a good way to achieve optimal results. The theoretical and practical aspects of the analysed process are pointed out. One solution to produce a forging by combined open and drop forging is presented.Item Blechsschneiden unter Anwendung von Materiallwärmung(University of Žilina, 2024) Moravec, JánIn the paper, the theoretical part presents the issue of metal cutting. The experimental part deals with the investigation of the influence of temperature during the application of heating. the text of the paper is supplemented by a discussion and at the end of the paper there is an evaluation of the obtained results. The contribution appropriately and well complements a wide range of sheet metal cutting problems.Item Konštrukčná úprava strižných hrán(University of Žilina, 2024) Moravec, JánThe 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.Item Klinové zváranie rúrok(University of Žilina, 2024) Moravec, JánThe 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.Item Aplikácia solenoidu pri magnetickom tvárnení(University of Žilina, 2024) Moravec, JánIn the contribution, the theoretical part points out the known starting points for calculating the inductance of a long cylindrical coil. In the practical part, the method of application of magnetic forming in the production of tins in lead samples is presented. The results confirm the correctness of the hypothesis.Item Magnetic forming with heat in a magnetic field(University of Žilina, 2024) Moravec, JánThe 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.
