Abstract

Sposób obróbki cieplno-plastycznej kształtowników wyciskanych ze stopów aluminium, zwłaszcza ze stopu AlMgSi(Cu), polegający na tym, że natychmiast po wyjściu z prasy do wyciskania, kształtownik przesyca się z temperatury wyciskania przez nagłe chłodzenie, a następnie chłodzi się go w na wybiegu prasy do wyciskania, po czym rozciąga się go do uzyskania odkształcenia trwałego, zaś po rozciąganiu kształtownik poddaje się procesowi sztucznego starzenia w podwyższonej temperaturze, charakteryzujący się tym, że rozciąganie kształtownika przeprowadza się najpierw przykładając do niego quasi-statycznie siłę rozciągającą, nadając mu naciąg wstępny w zakresie odkształceń sprężystych, po czym, zachowując naciąg wstępny, kontynuuje się rozciąganie w sposób dynamiczny. Przedmiotem zgłoszenia jest również przedstawiona na rysunku konstrukcja urządzenia do rozciągania kształtowników.A method of thermoplastic treatment of extruded sections made of aluminium alloys, particularly of AlMgSi(Cu) alloy, consisting in that immediately after leaving the extrusion press, the section is supersaturated from the extrusion temperature by sudden cooling, and then it is cooled in the run-out of the extrusion press, after which it is stretched until a permanent deformation is obtained, and after stretching the section is subjected to a process of artificial ageing at an elevated temperature, characterised in that the stretching of the section is carried out first by applying a quasi-statically tensile force to it, giving it a pre-tension in the range of elastic deformations, and then, while maintaining the pre-tension, the stretching is continued in a dynamic manner. The subject of the application is also the construction of a device for stretching sections shown in the drawing.
