Изобретение относитс  к обработке металлов давлением и может быть использовано в машиностроении дл  разделени  проката на мерные заготовки .The invention relates to the processing of metals by pressure and can be used in mechanical engineering for the separation of rolled metal into dimensional workpieces.

Цель изобретени  - повьшение качества получаемых заготовок.The purpose of the invention is to improve the quality of the resulting blanks.

На чертеже изображена схема осуществлени  способа на примере одной из разделительных операций обработк металлов давлением - резки проката сдвигом.The drawing shows the scheme of the method implementation on the example of one of the separation operations of metal processing by pressure - cutting shear.

Заготовку 1 помещают между втулочными ножами 2 и 3. Далее к заготовке подвод т контакты 4 и в течение операции резки пропускают через нее импульсы электрического тока плотностью 200 - 1000 М/мм с частотой 10 - 10 с . Применение импульсов электрического тока плотностью и частотой меньше указанныхThe workpiece 1 is placed between stub blades 2 and 3. Next, contacts 4 are brought to the workpiece and during the cutting operation, electric current pulses of 200-1000 M / mm with a frequency of 10-10 s are passed through it. The use of pulses of electric current density and frequency less than the specified
