ОБРАБОТКА МЕТАЛЛОВ № 2 (59) 2013 24 ОБОРУДОВАНИЕ. ИНСТРУМЕНТЫ The tool of magnetic-pulse repair technology based on combined matching device of cylindrical type Yu.V. Batygin, А.V. Hnatov, I.S. Trunova Kharkiv National Automobile and Highway University, Petrovskogo st., 25 Kharkov, 61002, Ukraine Abstract The electromagnetic processes analysis in the combined matching device that is presented by some base component of the tool for the non-contact electromagnetic metal forming technology of the dents removing in the sheet metals is conducted. The proposed design is a combination of proper matching device with an executive body, which significantly increases the level of energy transmitted from the source of power in the area of impacts to the object being processed. Analytical expressions for the components of the electromagnetic field excited in the system, and the currents, induced in the secondary coil of the metal considered constructive of the device were obtained by integration of Maxwell's equations. It is shown that the cylindrical geometry of the device made of, e.g., copper and being in actual pulsed magnetic metal processing time the current in the primary winding, conversion coefficient can reach its maximum value equal to the number of turns in the primary winding of the matching device considered. Research results are entirely consistent with those obtained from a previously published similar relationships for similar designs DC switching converters, which confirms the reliability of the conclusions of this work. The experimental results showed the high efficiency of the combined matching device cylindrical type of contactless technology for magnetic pulse alignment. Keywords: magnetic-pulse metal working, external magnetic-pulse straightening, matching device, transformer ratio. References 1.
