Abstract

Inventia se refera la un procedeu de formare a nufei de capat a unei tevi din material plastic în interiorul unui spatiu de prelucrat si fasonare prin care trece peretele capatului înmuiat al acesteia. Procedeul include cresterea unei prime portiuni înclinate spre exterior, pentru nmarirea razei tevii atunci cînd peretele din capatul sau înainteaza, a unei a doua portiuni înclinate spre exterior, dispusa în dosul primeia, marirea razei tevii prin avansarea peretelui din capat, precum si crearea unei portiuni înclinate spre interior, de la pareta superioara a primei pîna la partea inerioara a celei de-a doua, urmata de scurtarea razei, simultan cu avansarea capptului. Are loc largirea capatului tevii înmuiate în directie circumferentiala si în prima portiune înclinata spre exterior, simultan cu împingerea fortata a capatului tevii în directia axiala. Dupa aceasta, se realizeaza contractarea capatului înmuiat al tevii ce a trecut prin partea superioara a primei portiuni înclinate spre exterior, în directia circumeferentiala..........
