PROCESS OF TEST AND EVALUATION OF EFFICIENCY OF TECHNOLOGICAL LUBRICANTS |
摘要 |
FIELD: plastic metal working. SUBSTANCE: disc billet is held rigidly over contour and deformed to form recess in it. Second billet in which hole with diameter D<SB>o</SB> is drilled is used in addition. Lubricant is applied to surface of contact of punch and billet with hole. Two billets superimposed one on another are deformed simultaneously. Diameter D<SB>k</SB> of hole flanged with deformation in second billet is found. Efficiency of lubricant depends on the ratio D<SB>k</SB>/D<SB>o</SB>. EFFECT: elimination of effect of mechanical properties of sheet metal of billets on result of test. 2 cl, 1 dwg |
