Serdyuk O. The exploration is intense of the deformed condition of metal in dies with complex movement of knifes and perfecting of technology cuts of П-shaped structures.

Object of research - technology pieces in stamps. The purpose - improvement of quality of П-shaped structures on the basis of perfection of technology pieces and development of a design of a stamp with complex movement of knifes. Methods of the theory of plasticity and processing of metals by the pressure have been put in a basis of theoretical researches, including methods of mathematical modelling is intense - deformed conditions of the center of deformation with use of lines of sliding. Classification of movements of a mobile knife with reference to the circuit short closed pieces is developed. For the first time the method of definition of a direction pieces is developed and theoretically proved at progress of a knife of shaped angular and П-shaped structures. The mathematical model for definition power and geometrical parameters of process at the first stage of division is developed. Two circuits of complex rotationally-progress of a knife are developed and theoretically proved. Scope - the metallurgical and machine-building enterprises. The new "know-how" to the plug in accordance with GOST 22343-90 on Open Society " МК " Azovstal " is developed and introduced.
