MANUFACTURE INVESTIGATION OF CARTRIDGE WITH BOTTOM-MOST PART FLANGE BY DIRECT EXTRUSION WITH COUNTERPUNCH. REPORT 19. EXPERIMENTAL CHECK OF THEORETICAL RESULTS FOR DIFFERENT ANGLES OF DIE TAPER
Keyword(s):
The results of an experimental check of the obtained theoretical formulae allowing us to determine the most important parameters of extrusion of cartridges with a counterpunch for different angles of die taper are presented. Characteristics of used tools, geometric parameters of extrusion experiments, strength characteristics of deformed materials and lubricants are described in detail. Both strain-hardening material and strain-unhardening material were studied. Methodology of the theoretical calculations is demonstrated in detail. High accuracy of the obtained design formulae was confirmed.
