FIELD: process engineering.SUBSTANCE: invention relates to metal forming, particularly, to sheet stamping and can be used for production of sheets with branch pipes including those of out-of-round shape. Temporary hole in made in the part to form therein the branch pipe by burring with permissible burring factor. Note here that permissible burring factor is defined prior to pipe forming proceeding from the results of sheet tests before first crack formation. Specimen material elongation in the area of first crack formation is defined to set temporary hole diameter and tolerable burring factor.EFFECT: ruled out end crack formation.4 cl |
