FIELD: machine engineering.
SUBSTANCE: device contains a matrix, inside of which a punch is installed, and a punch-matrix which is made composite with a blind forming cavity that is adjacent to the end of the matrix. The punch-matrix consists of two-piece upper and lower semimatrix. There is a forming hemisphere cavity, divided along the centerline, in each semimatrix. The matrix and punch-matrix are enclosed in a shell and fixed by covers on both sides. The lower semimatrix can be made of four identical parts, and the upper semimatrix is made up of two identical parts.
EFFECT: improved quality of spherical products and saving powder by size pressing.
