FIELD: metal pressure forming, namely at sheet forming for drawing with use of technological holes, cutouts. SUBSTANCE: method comprises steps of applying coordinate network onto blank had been placed and having predetermined shape and dimension of its openings, cutouts; drawing that blank; investigating deformation field - loading type, deformation path of critical points according to deformation; selecting location of openings, cutouts, appointing their values and shapes; applying coordinates; drawing and repeating such actions until making high-quality part. EFFECT: lowered cost price of part due to using of low-grade drawing material with maintaining of high-quality of part. 1 cl, 3 dwg, 2 tbl |
