Abstract

The invention provides a double-shaft-shoulder friction stir tunnel forming method, and solves the technical problems that in the traditional friction stir tunnel forming process, a tunnel is small in size and unstable to form and the forming position is close to the surface of a plate. A double-thread structure of the double-shaft-shoulder friction stir welding tunnel machining device is used for enabling a metal plate center material to flow outwards, so that the tunnel can be formed in the center of the plate; the plane of the end surface of the double shaft shoulder and a vortex-shaped line groove alternate structure enable metal materials to be stacked on the upper surface and the lower surface of the metal plate and achieve welding while the pressing effect of the double shaft shoulder on the upper surface and the lower surface of the metal plate is achieved, and therefore the surface forming quality is guaranteed; double-face machining grooves are used for guiding out materials in the metal plate, the mobility of the materials is improved through cooperation with an auxiliary heating device, and finally, the continuous tunnel large in size and excellent in surface quality is formed in the metal plate. The method can be widely applied in the technical field of medium plate friction stir tunnel forming.

Description

technical field [0001] The invention belongs to the field of welding technology, and more specifically relates to a method for forming a double-shaft-shouldered friction-stir tunnel. Background technique [0002] With the advancement of science and technology and the continuous development of the material industry, lower cost, high efficiency, and easy-to-manufacture heat exchange devices and cooling systems are widely used in the automotive and aerospace fields. Tunnel processing technology can provide a higher surface area to volume ratio, so it can achieve higher heat transfer rate in the heat exchange device and reduce the volume of the device to achieve lightweight requirements. Therefore, tunnel processing technology is expected to become a new generation of high heat production equipment cooling system requirements one of the solutions. At present, tunnel processing technologies include electron beam processing (expensive, low processing rate), laser processing (expe...
