Abstract
Procedeul conform inventiei supune materialele, într-o prima faza, unei operatii de extindere, cînd are o vîscozitate ridicata, iar în a doua faza, se realizeaza tragerea tubului extrudat peste un dorn de calibrare interioara, în timp ce între tubul care nu este întarit total si dornul de calibrare se introduce un agent de alunecare, practicat fara presiune, astfel încît tubul extrudat antreneaza un strat de agent de alunecare între suprafata lui interioara si suprafata dornului de calibrare, strat a carui grosime pe lungimea dornului de calibrare se aduce progresiv, datorita unor forte radiale care actioneaza asupra tubului extrudat. Instalatia pentru realizarea procedeului este formata dintr-o presa melc pentru debitarea materialului termoplastic dintr-un dispozitiv de extrudare, format dintr-un corp si un dorn de extrudare, dorn care este cuplat direct cu un dorn de calibrare de îmbinare, s-a prevazut un spatiu inelar, în care se diriheaza un fluid de alunecare, fluid care trece liber prin dornul de calibrare si suprafata interioara a tubului extrudat, tub care este înconjurat de un schimbator de caldura, alcatuit din mai multe componente, pentru a raci sau a încalzi tubul realizat cu instalatia respectiva.The process according to the invention subjects the materials, in a first step, to an expanding operation when having a high viscosity, and in the second stage, pulls the extruded tube over an internal calibration mandrel, while between the non-cured tube and a pressureless sliding agent is inserted and the calibration mandrel is inserted so that the extruded tube drives a sliding agent layer between its inner surface and the surface of the calibration mandrel, the layer of which thickness along the length of the calibration mandrel is progressively brought, due to radial forces acting on the extruded tube. The apparatus for carrying out the process consists of a screw press for cutting the thermoplastic material from an extrusion device formed by a body and an extrusion mandrel which is directly coupled to a joint calibration mandrel, in which a sliding fluid is passed, a fluid that passes freely through the calibration mandrel and the inner surface of the extruded tube, which is surrounded by a multi-component heat exchanger to cool or heat the made tube with the respective installation.
