TECHNOLOGICAL PECULIARITIES OF STAMPING ON HYDRAULIC INERTIAL PRESS (GIP300) (TEKNOLOGICHESKIE OSOBENNOSTI SHTAMPOVKI NA GIDROINERTSIONNOM PRESSE GIP300),
FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OHIO
Pagination or Media Count:
An experimental model of a hydraulic-inertial press of 1000 kn capacity with a ram vibrating up to 19 cps and a 160-kw drive was designed at ENIKMash. It is intended for direct or reverse extrusion, upsetting, heading, trimming, and drawing. Tests of AD1 aluminum and AK6 aluminum-alloy specimens 35 mm in diameter conducted at room temperature and vibration frequencies in the range 8--15 cps showed that the force required for direct or reverse extrusion with a vibrating load was lower by 10--50 than that required for upsetting AD1 aluminum by 30--60, and that required for stamping steel plate by more than 60. The specimens surface was polished after trimming with a cutting die with radial edges and grease and kerosene used as lubricant. Vibration increased the deep drawing of brass, 3-steel, and 08-steel sheet specimens to 45 mm, and decreased the drawing coefficient by 10--15.
