The aluminum profile straightener includes a relatively set fixed stretching head and a moving stretching head. The fixed stretching head is set on the stretching track. The moving stretching head controls the movement through the connected main straightening cylinder. It is characterized in that it also includes a control system, a laser rangefinder and a pressure sensor set on the moving stretching head. The control system records the parameters of the laser rangefinder and the pressure sensor, It can also control the straightening parameters of the moving stretching head. This new aluminum profile straightener can improve the function of memorizing profile straightening parameters, make the straightening process more uniform, reliable, and improve production efficiency. It is very suitable for straightening aluminum alloy parts of aircraft.
