Abstract

Inventia se refera la un procedeu pentru realizarea racordurilor de tip teuri, laterale sau reductii din semifabricate sub forma de teava. Procedeul, conform inventiei, consta în umplerea unui semifabricat sub forma de teava cu lichid la presiune atmosferica, semifabricatul fiind introdus într-o matrita prevazuta cu un canal vertical, dupa care se scoate aerul din lichid pe la partea superioara a matritei. Se etanseaza apoi teava prin presare usoara la capete actionând doua poansoane laterale. Dupa etansare, în interiorul semifabricatului se introduce lichid de la o sursa de presiune medie, printr-un canal longitudinal practicat într-unul din poansoanele laterale si se preseaza lateral, pâna ce teava se deformeaza corespunzator în canalul vertical al matritei. Presiunea din interiorul semifabricatului este corelata cu presarea laterala, datorita unui ventil proportional ce utilizeaza semnalul primit de la un traduxctor de deplasare. Procedeul permite eliminarea surselor de presiune înalta determinând astfel reducerea consumului de energie.
