FIELD: mechanical engineering. SUBSTANCE: pressing tool has body 1, matrix 2 positioned in cavity of body 1. Matrix 2 is formed as square prism with holes in sides. Hole axes are offset one with respect to the other and are separated by equal distance from matrix sides. Axis of punch 7 is offset relative to body cavity axis of symmetry for value equal to half the distance between hole axes. EFFECT: increased efficiency, simplified construction, enhanced reliability in operation. 2 dwg
