Object of research - machines and equipments of the different setting. Methods of research - development of mathematical models, experimental devices and leadthrough of experiments. Theoretical and practical results - information is got about the sizes of general energy of deformation and destruction, and also its constituents, duration of different phases of destruction, and speed of main crack for materials with different mechanical properties at a shock ladening on the chart of the three-point cold breaking by a bend with the use of the multichannel system of high-speed registration of efforts; conclusions are done about influence of speed of ladening on durabiliteble properties and geometrical exactness of purveyances, got the method of the three-point cold breaking by a bend at the static and shock division of standards from the different brands of steels; expedience of application is grounded in presses for realization of dividing processes of wedgeshinge mechanism with a concave wedge at which the chart of change of force of ladening is most close to the technological model chart of change of force at a division, researches of this mechanism are conducted, on the basis of analysis of the offered mathematical models the method of calculation of wedgeshinge presses with a concave wedge and construction is developed the press by effort 4 MN for dividing operations. Novelty - on the basis of scientific analysis and researches structural and technical decisions were found on the increase of exactness, reliability and longevity of mobile connections, in the process of exploitation of machines. Got further development of conformity to law and connection of the power modes of dividing technological operations of treatment pressure with kinematics and dynamic descriptions the press; with the use of the developed mathematical models dependences are exposed for the calculation of basic geometrical, kinematics and power parameters of wedgeshinge mechanism of presses with a concave wedge as it applies to dividing operations;got further development of picture of conformities to law of ladening of presses with a wedgeshinge mechanism with a concave wedge at implementation of dividing operations, allowing to ground the necessity of account of resilient deformation of executive mechanism, forces of friction in it and to offer the new charts of technological equipment for implementation. An application domain is production of machines and equipment, repair and technical maintenance of pumps, compressors and hydraulic systems.
