DIE SET FOR EQUAL-DUCT ANGULAR PRESSING (VARIANTS)

摘要

FIELD: plastic metal working with use of intensive plastic deformation, namely manufacture of nano-crystalline materials with improved degree of mechanical properties. ^ SUBSTANCE: die set includes slider and plate restricting inlet duct; stationary stop closing inlet duct and restricting together with plate outlet duct; ram and member for knocking out blank. Said member is joined with motion drive unit and it is mounted with possibility of introducing into additional through duct formed in slider. According to first variant of invention at initial position of slider its through duct is arranged in front of outlet duct. Slider may be shifter before starting pressing process by value exceeding size of through duct. According to second variant of invention through duct of slider is arranged in front of outlet duct in lower limit position of slider. Said cone-shape through duct of slider is closed by means of plug pressed-in to it. ^ EFFECT: improved design providing possibility for extracting last blank out of outlet duct before starting pressing of next lot of blanks. ^ 2 cl, 5 dwg
