Here investigated influence of values of pressure of puncheon in the chosen range of stand, forms of walls of instrument and friction of material without and with the use of greasing on character of plastic section and on the basis of foregoing methods of calculation (method of hard blocks, CAE - analysis) carried out comparing of the got results to the last for the classic method of sliding lines. By means of two original metallic shrouded sectional stamps and standard hydrohammer the equichannel angular pressing of purveyances produced from metals and materials are in solid phase (powders); investigated influence of linear and angular parameters of deformation channel of the equichannel angular pressing on the basis of both physical (liquid) and numeral models of continuous environments (method of overhead estimation, method of eventual elements). The choice of energypower and geometrical parameters of purveyance for the transversal and transversal-spiral rolling was conducted experimentally by means of the specialized laboratory setting of 3х60- 160, projected and made in Donbass state machine-building academy, worked out to recommendation on the choice of technological parameters of processes of production of axisymmetrical ribbed metal products. The structural features of transmissions are considered with relatively by the mobile cylindrical elements of hooking and recommendations over of their calculation are brought on durability. he optimal mode of hitting is chosen " flywheel-anvil" in the system "A thin- percussive impact wrench is screw-thread connection", at which a transmitivity of energy at hitting is maximal. For the choice of optimal parameters of protective bimetallic slats in the cages of flattings mills : material, hardness, thickness of plating layer, correlation of thicknesses of it and parent metal was used technical documentation of figure 2000 by Novolipetsk Steel (NLMK), subject to the reconstruction. The improved construction of the shrouded stamps with collapsible holders was exposed to pressed in them insertions the experienced verification at the operations of stamping and calibration carried out on electro-spiral presses, where used the preliminary extruded purveyances. Results - the necessary experimental researches were maked, design procedures for working methols and corresponded equipment.
