Abstract

Inventia se refera la un procedeu si la un dispozitiv pentru realizarea manetoanelor pentru realizarea manetoanelor pentru arborii cotiti frezati, care consta din realizarea unui semifabricat de pornire prin forjare libera si matritat în douafaze separate de matrite permitînd obtinerea unor manetoane cu fibraj continuu si cu dimensiuni apropiate de dimensiunile manetoanelor în stare finita. în prima faza de matritare se realizeaza profilul superior si inferior al manetonului respectiv dupa care în a doua faza de matritare se realizeaza fusul manetonului. Prima faza de prematritare se realizeaza cu o matrita alcatuita dintr-o parte exterioara a carei suprafata interioara este înclinata si în contact cu niste adausuri care împreuna cu un poanson dau forma exterioara a manetonului. Forma definitiva se realizeaza cu un alt poanson.The invention relates to a process and a device for making manikins for making the crankshaft crankshafts, which consists of the realization of a freeform molding blank and molded into two separate molds allowing to obtain continuous and close-sized fiber of the size of the manikins in the finished state. In the first molding stage the upper and lower profile of the manikin is made, after which in the second molding stage the spindle of the manikin is made. The first phase of prematriction is performed with a mold made of an outer part whose inner surface is inclined and in contact with some additions which together with a punch give the outer form of the manikin. The final form is made with another punch.
