FIELD: mechanical engineering.
SUBSTANCE: invention relates to collapsible dies for drawing wire and profiles. The die contains a frame, pressure screws and working dies, which are a steel base in the form of a rectangular plate with a carbide solder on its working side with a working zone having a deforming, calibrating and output zones with a ratio of the length of the output zone to the total length of the working zone in the range of 0.24-0.32. The steel base is made in the form of a rectangular container filled with at least one layer consisting of two rows of tetrahedra. The vertices of the tetrahedra in each row are directed to opposite sides, and their bases lie on the boundaries of this layer.
EFFECT: rigidity and durability of the die increases.
