Description
Известны способы упрочнени металлических изделий путем поверхностного наклепа, в том числе и на спепа струей воды. Однако в них примен ют струю, F ыпycкaeмyю под относительно небольшим давлением, а дл усилени действи з нее ввод т металлическую дробь.Methods are known for hardening metal products by surface work-hardening, including with a stream of water. However, they use a jet, which is fired under relatively low pressure, and metal shot is introduced to enhance the effect of it.
Особенность насто щего способа повышени усталостной прочности металлических изделий, заключаетс в том, что, с целью повышени эффективности воздействи струи, используемую дл удара жидкость подвергают сжатию под сверхвысоким давлением.The peculiarity of the present method of increasing the fatigue strength of metal products is that, in order to increase the efficiency of the impact of the jet, the liquid used for the impact is subjected to compression under ultrahigh pressure.
Способ заключаетс и том, что предварительно сжата до нескольких сотен атмосфер стру жидкости от насосного блока через насадок подаетс под углом на поверхность обрабатываемого металлического (гздели . При обработке стру перемещаетс относительно издели .The method also consists in the fact that a fluid jet from the pumping unit is pre-compressed to several hundreds of atmospheres through nozzles at an angle to the surface of the metal to be treated (at the exit. During the treatment, the jet moves relative to the product.
