Description
Technical Field
The invention relates to the field of material surface treatment and processing, in particular to a pressure induction feedback type ultrasonic and electric pulse composite rolling treatment device.
Background
10 percent of steel produced in every year in the world can be corroded into rust, 30 percent of steel equipment is damaged, various mechanical equipment has the phenomena of short service life, high energy consumption and the like due to fatigue fracture, abrasion and corrosion, the economic loss brought to China every year reaches hundreds of millions of yuan, materials are wasted, and the problems of production stop, safety accidents, environmental pollution and the like are also brought. For reasons, the failure modes of mechanical parts such as fatigue fracture, abrasion, corrosion and the like are mostly started from the surface of the material, and from the viewpoint of environmental protection and sustainable development, the surface strengthening processing is carried out on the material, and the improvement of the surface property of the mechanical parts is greatly necessary for industrial production.
At present, various processing methods such as electroplating, shot blasting, rolling and the like are adopted by various countries for improving the surface properties of mechanical parts, such as hardness, corrosion resistance, wear resistance, fatigue resistance and the like, but the processing methods have limitations and defects of the processing methods.
Electroplating is a process of plating a thin layer of other metals or alloys on the surface of some metals by utilizing the electrolysis principle, has simple structure and process and low cost, but a large amount of chemical medicines such as strong acid, strong alkali, salts, organic solvents and the like are used in the electroplating production, and a large amount of toxic and harmful gases are emitted in the operation process, for example, the safety management work is not good, and poisoning and burning are easy to occur, so that the combustion and explosion accidents are caused. On the other hand, the work site of the electroplating workshop is wet, equipment is easy to corrode, and electric shock accidents are easy to cause.
The shot blasting is to spray high-speed shot flow to the surface of a part to enable the surface layer of the part to generate plastic deformation so as to form a reinforcing layer with a certain thickness, and high residual stress is formed in the reinforcing layer. The shot blasting treatment has the advantages that various products with complex shapes can be treated, but the shot blasting treatment has poor working environment, low unit yield, low efficiency ratio than shot blasting, and incapability of accurately ensuring the size, and is suitable for non-matching surfaces.
The rolling is a plastic working method in which a high-hardness and smooth roller is brought into rolling contact with a metal surface to cause a local slight plastic deformation of the surface layer, thereby improving the surface roughness. After the surface of the metal workpiece is subjected to rolling processing, the surface layer obtains enhanced ultimate strength and yield point, and the service performance, fatigue resistance, wear resistance and corrosion resistance of the workpiece are obviously improved. But the hardened layer generated by rolling will be connected with the inside
The material has obvious layering phenomenon, the surface layer is easy to fall off, and the rolling process is difficult to master and is improper to treat, so that waste products are easy to cause.
