METHOD FOR PRODUCING BLANKS CASE TIP

摘要

FIELD: process engineering.;SUBSTANCE: invention relates to metal forming and may be used for production of parts like brake hose nozzles. After straightening of blank ends, smaller-diameter section is directly extruded at the blank. Then, indirect extrusion is used to form inner cavity. At the next forming position, flange is swaged at the blank and, at a time, conical bearing surface is headed at inclination to blank axis making at least 5 degrees. Then, smaller-diameter inner cavity is extruded and said flange is cut to hexahedron.;EFFECT: higher quality of finished products.;1 dwg
