Abstract

Inventia se refera la un sistem hidraulic de actionare a unei prese pulsatoare utilizata, în special la deformarea plastica a materialelor metalice, fiind alcatuit din niste servomotoare care permit o reducere a consumurilor energetice în timpul presarii si o crestere a stabilizarii parametrilor fortei de presare. Ambele servomotoare hidraulice sunt amplasate într-un corp comun si lucreaza axial prin intermediul unui piston cu doua etaje de lucru care formeaza niste spatii de lucru este în legatura cu niste distribuitoare si cu un generator rotativ de pulsatii.
