aluminium alloy AA6063 - Opis:
- This work deals with the tube sinking process. The main purpose is to develop a process chain for the manufacturing of ultra-thick-walled tubes with the lowest possible diameter. The base material is a hot extruded tube consisting the aluminium alloy AA6063 with the dimensions 9,9 ×1 mm. The drawing tools include several dies with various exit holes, a drawing bench and a muffle oven to produce ultra-thick-walled tubes with dimensions 5,02…5,03 × 1,54…1,59 mm. The process has been applied successfully. With a double-layered tube, it was possible to reach a low diameter/wall-thickness ratio of 3,3 at tube sinking process. Subsequent pull-out tests showed that by reaching the threshold outer tube diameter value of Ø 5 mm the joining strength increased from 1,3 MPa to 6,2 MPa. It could be observed that the heat treatment reduced the joining strength for the double-layered tubes with diameter of 5 mm, whereupon for the bigger tubes diameter it has no significant influence on the joining strength.
