Abstract
Способ изготовления полых осесимметричных изделий с отверстием в донной части, включающий вырубку плоской заготовки с диаметром отверстия меньшим диаметра отверстия в донной части готового изделия, отличающийся тем, что производят раздачу кромки отверстия, а формообразование полуфабриката осуществляют предварительной вытяжкой, совмещенной с отбортовкой, до достижения предельно допустимой деформации на кромке отверстия без существенного утонения, затем удаляют наиболее упрочненный материал краевой части отверстия полуфабриката разверткой и осуществляют окончательную вытяжку - отбортовку до получения готового изделия. A method of manufacturing a hollow axisymmetric products with a hole in the bottom, including cutting a flat workpiece with a hole diameter less than the diameter of the hole in the bottom of the finished product, characterized in that they distribute the edges of the hole, and the formation of the semi-finished product is carried out by preliminary drawing, combined with flanging, until reaching the maximum permissible deformation on the edge of the hole without significant thinning, then the most hardened material of the edge part of the hole of the semi-finished product is removed with a screwdriver and carry out the final drawing - flanging to obtain the finished product.
