EVEN CHANNEL ANGLE EXTRUDER

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to metal forming. Extruder comprises shell ring, male die and female die. Female die has at least three intersecting inlet, intermediate and discharge channels. Inlet and discharge channels feature square section, while intermediate channel has screw cross section. Lead angle makes 2-11. Intermediate channel length does not exceed 6H where H is the length of face of inlet and discharge channel cross section square. Note that split female die is used. ^ EFFECT: higher intensity of fine-grain structure formation and homogeneity of structures extruded. ^ 2 dwg, 1 tbl
