FIELD: metallurgy.
SUBSTANCE: invention relates to metal forming, namely, to forming of parts, type of casings, by stretch forming of a movable die. Sheet of film material with a lubricant applied to both sides is put on the movable die and tightened until it is completely seated. Layer of film material with a lubricant applied on both sides is freely laid on the workpiece and, together with it, laid on the movable die. Lubrication as adhesive maintains a layer of film material on the workpiece. Ends of the workpiece are fixed in the clamps of the tightening press. With the help of the press, the workpiece is stretched over the movable die.
EFFECT: technological possibilities of the method are expanded due to the manufacture of parts of complex profile, and the uniformity of deformation is increased.
