Research of the process of cold breaking of rolling by bending under static and shock loads was conducted to determine the effect of loading speed on the power parameters of the separation process and the quality of the workpieces. Experimental researches are conducted for the three-point cold breaking by bending of templates from steel of different brands at the static and shock loading with the use of original equipment and rigging. Comparison of maximal force of breaking at the static and shock loading was estimated by the coefficient of dynamic, which for the different brands of steel laid down accordingly: ШХ15 - 0,7; 60С2 - 1,6; 45 - 2,0..2,2; 40Х - 1,8..2,1; 20 - 1,6..1,8 at speed of deformation to 18 m с. At the increase of speed of deformation the coefficient of dynamic grows for materials in the plastic and viscidly-resilient state and diminishes for materials in the fragile state. Than higher plasticity of material of templates, the greater size of coefficient of dynamic.
Obviously, that for the exposure of inclination of materials of templates to fragile destruction it is necessary to apply the higher values of speed of loading. With the growth of speed of deformation geometrical exactness of blanks from the different brands of steels, gets better, but not significant. The most high quality was shown by blanks at the division of standards from fragile and viscoelastic steels: ШХ 15, steel of 60С2, steel 45, steel of 40Х. It is identified that greater part of energy of deformation is spent on an origin and viscid growing up of crack, while energy expended on fragile destruction is insignificant. Got results can be used for the improvement of the technologies of process of division of grade rolling on the measured blanks by the method of the cold breaking by a bend.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
