| Popis: | The aim of the work is designing of the new schemes of cut-to-length workpieces of rolled stock and equipment for their implementation. A special construction of the equipment for cutting by breaking of rolled stock has been designed. The energy accumulated into hydro press at the expense of elastic deformation of the machine frame and the drive is used for effective work, namely, application of stress concentrator for cutting by breaking the next workpiece. Mathematical model for indentation of the wedge tool with different form has been designed. Dependences for calculation of energy-power parameters of the process of stress concentrator application have been found. Experimental studies of indentation of the wedge-shaped tool with different forms into the sample confirmed the adequacy of the proposed mathematical models. Calculating errors within 5–10% is related to the need for a more correct choice of the value of sliding friction coefficients. Calculations for steel C 20 (0.2% of the carbon) with triangular stress concentrator show that the amount of accumulated energy of elastic deformation of the machine frame and the drive of hydraulic press will be enough for application of the effective stress concentrator for cutting by breaking the next workpiece (taking into account the bluntness of the cutting edges of the wedge knife). |
