Description

one

The invention relates to the field of mechanical engineering, machine-tool construction, instrument-making and can be used in the processing of metals and other materials by pressure without chip removal (cold stamping).

A matrix is known, containing four inserts made in the form of elongated rectangular parallelepipeds arranged in a cage in one plane perpendicular to one another and forming a closed loop L U

The disadvantage of this matrix is narrow technological capabilities.

The aim of the invention is to expand the technological capabilities of the matrix.

The goal is achieved by the fact that a matrix containing four inserts, made in the form of elongated rectangular parallelepipeds, located in the cage in one plane, perpendicular to one another and forming a closed loop, is provided with longitudinal and transverse displacement of parallelepipeds relative to each other, type of screws with conical ends located in the walls of the cage, while on the front and one of the side surfaces of each parallelepiped there is a groove with scrap at the top of 90, for guiding the conical end of the pressing screw.

The proposed device consists of inserts 1, 2, 3 and t, which are made in the form of parallelepipeds, arranged perpendicular to each other in a rectangular recess 5 about 6 in one plane. To fix the parallelepipeds in the working position and move them relative to each other, pressure screws 7 are used to achieve this position, which are located one at the end of each parallelepiped and two on the side of it. Clamping screws are made with a tapered end 8, and parallelepipeds with grooves 9 and 10. The matrix works as follows. To cut a part with dimensions O and B (see Fig. 2 parallelepipeds f, it is necessary to move relative to the end face of parallelepiped k to distance Q, and parallelepiped 2 along side surface of parallelepiped k to contact end surface of parallelepiped 2 with side surface of parallelepiped 1 , the parallelepiped 2 is moved to the distance OL Then parallelepiped 2 is neo (5 you need to move relative to the side surface of the liner 1 to the distance {j, parallelepiped 3 will move along the end surface of the liner until contact with the side surface of parallelepiped 2 at a distance b. Thus, we obtain a closed loop with specified dimensions O and use of the invention will allow us to obtain significant savings in expensive tool steel as well as other materials, greatly reducing the time of manufacturing parts while improving their quality The use of the invention will also make it possible to save a lot of working time of several highly skilled workers, which were previously used to produce tools. ment for each batch deta-.
