MANUFACTURE INVESTIGATION OF CARTRIDGE WITH BOTTOM-MOST PART FLANGE BY DIRECT EXTRUSION WITH COUNTERPUNCH. REPORT 17. EXPERIMENTAL CHECK OF THEORETICAL RESULTS WITH USE OF STRAIN-HARDENING MATERIAL
Keyword(s):
Results of the experimental check with the use of strain-hardening material, which was carried out for the obtained theoretical formulae allowing one to determine the most important parameters of the cartridge extrusion with a counterpunch, are presented. Methodology of the theoretical calculations, characteristics of used tools, geometric parameters of extrusion experiments, strength characteristics of deformed materials, as well as lubricants are described in detail. The high precision of obtained design formulae was confirmed.
