Online extruding and quenching process and device for aluminum profiles

The invention discloses an online extruding and quenching process and device for aluminum profiles. The online extruding and quenching device comprises a shell. A base plate is slidably connected to the bottom of the interior of the shell. A cavity is formed in the base plate. An external shaft is fixedly connected to the bottom end of the base plate. An internal shaft is slidably connected to theinner side wall of the external shaft. A to-be-quenched aluminum profile is placed on a rotary table at the top of the base plate, the rotary table drives the internal shaft to rotate, then a drivinggear is driven to rotate to drive a driven gear, and then a lead screw rotates; through the arrangement of an external thread, a sliding block moves inwards to drive a fixing plate through a connecting rod to move inwards to extrude the aluminum profile; a motor drives the base plate and the aluminum profile to rotate, cooling liquid is evenly sprayed on the surface of the rotating aluminum profile through a spray pipe du
