By the Purpose master's of operation is: Development Idealized design techniques of sizings for rolling sprockets from bar with the previously prepared ripple .
For reaching the indicated purpose in master's to operation are resolved, following, Problems:

• The Browse of state of the art of production of railway sprockets by a processing techniques of metals by pressure.
• the Analysis of the existing "know-how" formed and stampedrolled of sprockets.
• the Analysis of idealized computational methods of technological modes of a strain and sizings of rolls mill of rolling sprockets.
• the Analysis of experimental researches of geometrical and technological parameters of process of rolling.
• Development of idealized design techniques of sizings for rolling sprockets from bar with the previously prepared ripple.
• Milestones of development of the new "know-how" stampedrolled of sprockets.
• Development of a method and program of designing new without conic merging(ingots) and precise bars for an extrusion of wheel bars in the closed title block.
• the Circuit(scheme) of production stampedrolled of sprockets from precise bars eliminating asymmetry for want of to an extrusion of wheel bars.
• Setting and development of a method of a solution of a boundary value problem of rolling of a sprocket from wheel bar with the previously prepared ripple.
• Development of a design technique of sizings for rolling sprockets from bars with the previously prepared ripple.
• Development of the new "know-how" mass profiledimension of sprockets a dia of 957 mms in intended a field of the admissions.
• Technology precipitations of precise bars on presses by gain 20 МН and 50 МН.
• Technology of an extrusion of wheel bars in a selfcontained title block on press by gain 100 МН.
• Technology of rolling of draft-quality sprockets on mill of rolling sprockets.
• Technology of calibration of sprockets on press by gain 35 МН.

Urgencies of a theme

   

By Such by image, program design, which one for want of introduction of the definite data, namely coordinate of points of interface of an outline, could construct an outline of a sprocket and to trace his(its) modification for want of to rolling. Such program in the long term lie in the basis(fundamentals) of accounts of sizings, with the purpose of tracing form-building of current of metal, filling and high infill of calibres.
