Abstract

The invention discloses a magnesium-aluminum alloy plate softening method and relates to the technical field of alloy processing. The method comprises the following steps that firstly, electrifying is carried out on an electromagnetic disc so as to keep the arrangement state of a plurality of friction blocks arranged in an array along with the concave-convex change of the surface of a magnesium-aluminum alloy plate, and full fitting is carried out to finish shaping; then a vibration exciter arranged on the side walls of friction box bodies is started, the vibration exciter vibrates violently to drive the friction box bodies to vibrate violently, the plurality of friction blocks completely attached to the surface of the magnesium-aluminum alloy plate generate tiny relative displacement under the action of vibration, the magnesium-aluminum alloy plate and the friction blocks are in violent friction with each other, heat is generated, through a working mode and the the friction box bodies which are symmetrically arranged, the temperature of the surface of the magnesium-aluminum alloy plate is increased at the same time, gradual softening is carried out, meanwhile, heating is uniform, softening is thorough, and the magnesium-aluminum alloy plate flattening and correcting device and the method are used for solving the problems of how to uniformly heat, how to pressurize to avoid cracks and how to overcome uneven thickness in the prior art.
