METAL PLASTIC WORKING APPARATUS

摘要

FIELD: apparatuses for strengthening metals during working them. ^ SUBSTANCE: apparatus includes die having two mutually crossing ducts in crossing place of which rollers are mounted with possibility of rotation. Diameter of roller in zone of crossing of vertical wall of upper duct with lower wall of horizontal duct exceeds diameter of said roller in zone of crossing of vertical wall of upper duct with upper wall of horizontal duct. Centers of rollers are on line connecting zones of duct crossing. In order to work blanks in the form of round rods, rollers may be concave ones and for working blanks in the form of rectangular prisms rollers may be in the form of round cylinders. ^ EFFECT: improved mechanical characteristics and quality of worked blanks. ^ 5 cl, 2 dwg
