FIELD: metallurgy.
SUBSTANCE: invention relates to metal deformation process and can be used in punches for punching of openings simultaneously in two and more shelves of detail, located at different levels, and allowing greater tolerances for dimensions between shelves. Top mobile and bottom parts are aligned by means of columns and bushes. Top part contains of top plate and carrier with located in it two puncheons of different length and pressing. Bottom part consists of bottom plate, carrier with two matrix, located on different levels and pressing. Floating units, operating for self-adapting of puncheons and/or matrix, are located in top and bottom parts of punch, accordingly. Each of it is implemented in the form of spacer block with groove, supports, located in groove of mentioned spacer block with ability of pumping, and step-bearing, located on bearing and interacting with matrix and puncheon, accordingly.
EFFECT: it is simplified construction and service of punch.
