In the equipment, the specific structures of a mounting base, a centering and clamping device, a working head clamping device and a mobile platform are designed; through flexible cooperation of the components, the efficiency of spraying a protective coating before forming of the superplastic diffusion surface of the hollow titanium alloy wing rudder and the efficiency of removing a pollution layer after forming of the superplastic diffusion surface of the hollow titanium alloy wing rudder are improved.

Description

technical field [0001] The invention belongs to the field of mechanical engineering, and relates to a device and a method for protecting and cleaning the superplastic diffusion surface of a hollow titanium alloy wing rudder. Background technique [0002] During the high temperature forming process of titanium alloy products, the surface preferentially adsorbs oxygen to form a pollution layer, which will reduce the forming performance of the titanium alloy and shorten the service life of the titanium alloy. In terms of surface protection, glass protection lubricating materials of borosilicate glass are mainly used by hand, which is not only inefficient, but also difficult to control the quality of the coating. In terms of surface contamination layer removal, the formulation of the conventional alkali ablation and pickling process actually lacks effective data support, and the method for removing the contamination layer cannot meet the needs of mass production. At the same tim...

Problems solved by technology

[0002] During the high-temperature forming process of titanium alloy products, oxygen is preferentially adsorbed on the surface to form a pollution layer, which will reduce the formability of titanium alloys and shorten the service life of titanium alloys

In terms of surface protection, glass protection and lubricating materials that are sprayed with borosilicate glass by hand are mainly used. This method is not only inefficient, but also difficult to control the quality of the coating.

In terms of surface contamination layer removal, the formulation of the conventional alkali collapse pickling process actually lacks effective data support, and the method of removing the contamination layer cannot meet the needs of mass production. At the same time, the wastewater and waste gas generated by this process will cause harm to operators and the environment. Certain hazards, the production is very easy to stop production and limit production due to environmental protection control requirements; at the same time, the outer surface of the titanium alloy wing rudder is relatively complicated, and if there is no corresponding tooling, the front and back cleaning with the same laser parameters will have the same effect. will make a difference

[0003] Therefore, it is urgent to design a device to improve the efficiency of spraying the protective coating before the superplastic diffusion forming of the hollow titanium alloy wing rudder and removing the contamination layer after forming. At present, there is no patent related to this device
