The number of rollers raskatnoe head is chosen equal to the number of faces of the pyramid.

The device for implementing the method of forming according to the invention contains a step matrix consisting of cylindrical and versatile pieces and also multi-roll belt raskatnoe head.

Multifaceted part of the matrix acts as a stripper and made with a number of faces equal to the number of sides of the pyramid. The number of rollers raskatnoe head is equal to the number of faces of the pyramid.

The drawing shows a device for forming according to the invention (rescata head not shown).

The step matrix consists of a cylindrical part 1 of the matrix with cutoff ring 2 and multifaceted part 3 matrix.

When the function is executed puller multifaceted part 3 matrix is driven by a pneumatic cylinder 4 by means of the pushers 5.

Size "B" multi-faceted part of the matrix is performed is equal to the diameter of the cylindrical part of the matrix, and the size of the "h" calculated taking into account the guarantees touch the edges of the "C" planes of the faces of the pyramid when installing billet (pyramid) in the cylindrical part of the matrix with a touch of edge "d" on the circumcircle.

When clicking on the table of the drilling machine, and multi-roll belt rescata head is attached to the spindle. The formation process using the device according to the invention can be implemented on different hardware (boring, turning, turning, metal spinning), but the most economically feasible is the handling of drilling machines.

The smaller cross section of the pyramid do with so that she was in contact with the cylindrical portion of the matrix on the circumcircle with the creation of the field "And" sufficient for forming a cylindrical pipe and cutting his face.
