Abstract

Inventia se refera la un procedeu si la un dispozitiv pentru prelucrarea prin presare a materialelor în stare plastica, care permit un consum energetic scazut prin utilizarea mai multor faze în procesul de presare presare care poate fi adaptata în functie de natura materialului si de operatia de prelucrare impusa de tehnologia de fabricare a pieselor, respective avînd aplicabilitatea la forjare perrforare brichetzare injectarea maselor plastice s.a. Fiecare faza cuprinde o etapa de energie mare, pe o durata relativ mare de timp. în faza respectiva se utilizeaza energia acumulata de niste elemente elastice deformabile de legatura cu un sistem de came si de pîrghii articulate.
