FIELD: technological processes. ^ SUBSTANCE: stretching is carried out in one punch, elements of which are puncheon and matrix. In the end of puncheon travel local bends of part are carried out by application of one stamp elements with working surface, which is arranged in the form of structural elements projection-cavity under the condition of stretching accuracy provision by redistribution of internal stresses depending on value of mentioned bends of part. ^ EFFECT: higher accuracy of making parts with larger radiuses. ^ 4 cl, 3 dwg |
