Abstract

Inventia se refera la un procedeu si la o matrita pentru realizarea pieselor prin turnare sub presiune, utilizate, în special, la realizarea vîrfurilor de geometrie variabila de la corpurile focoaselor pentru diferite arme de foc. Procedeul consta din confectionarea vîrfului de geometrie variabila dintr-un aliaj de aluminiu cu rezistenta la tractiune cu aproximativ 33 daN/cm2 cu o forta de presare de 1,57 x 10 la puterea 5 N si la o temperatura de 690-710 degree C. Matrita pentru realizarea procedeului este alcatuita dintr-o parte mobila si din niste miezuri pentru a realiza forma interioara a vîrfului de geometrie variabila. Unul din aceste miezuri este coaxial cu o bucsa extractoare.
