Abstract

Inventia se refera la tehnologia constructiilor de masini, si anume la formele de presare pentru obtinerea pieselor din pulberi metalice.Forma de presare pentru pulberi metalice contine o bucsa de strângere (3), în care sunt amplasate o matrita (2) si elemente de formare de sus (4) si de jos (5), executate în forma elicoidala cu proeminente interne în partea de jos, care în asamblare formeaza o suprafata cilindrica, si amplasate cu posibilitatea deplasarii reciproce dupa o traiectorie curbilinie de-a lungul axei de presare. Forma de presare mai contine un miez (7) si un poanson (6), care împreuna cu elementele de formare (4, 5) formeaza cavitatea de presare.
