Pulse water jet coating peeling and finishing equipment

Abstract

The invention relates to a coating peeling, surface finishing and burring equipment, in particular to pulse water jet coating peeling and finishing equipment comprising a protecting cover. The protecting cover is provided with collecting box inside, the side of the collecting box is fixedly provided with a robot executing mechanism, a sprayer device is fixed to the front end of a moving arm of the robot executing mechanism, the surface of a high-pressure generating device is provided with a pressure regulator, the high-pressure generating device is connected to the sprayer device through a high-pressure pipeline, the upper end of the sprayer device is fixed to an ultrasonic transducer connected to an ultrasonic generator through a cable, and the lower end of the ultrasonic transducer is connected to a high-pressure water jet sprayer; the top of the protecting cover is provided with a fog absorbing device, and the fog absorbing port of the fog absorbing device corresponds to the washing station of the sprayer device. By the aid of the finishing equipment, carbon deposition and coating of the surfaces of aerospace engine parts, the parts can be washed, and the surfaces can be finished.

Description

technical field [0001] The invention relates to a coating stripping, surface finishing and deburring device, in particular to a pulse water jet coating stripping finishing equipment. Background technique [0002] At present, in the repair of jet engine blades, high-pressure turbine couplings, flame tubes and other parts in the domestic aviation and aerospace fields, the carbon deposits, coating stripping, removal and cleaning are mainly used for lathe cutting, manual grinding, Chemical reagent immersion corrosion and other methods. Disadvantages of using this kind of process to remove carbon deposits and coatings: 1. It is easy to damage the substrate of the parts, causing the parts to be scrapped; 2. The efficiency of manual grinding is low and the cost is high; 3. The chemical reagents pollute the environment and cause harm to the operators. In developed countries in Europe and America, the coating peeling and removal of such parts is realized by ultra-high pressure water...

Disadvantages of using this kind of process to remove carbon deposits and coatings: 1. It is easy to damage the substrate of the parts, causing the parts to be scrapped; 2. The efficiency of manual grinding is low and the cost is high; 3. The chemical reagents pollute the environment and cause harm to the operators.

Due to the high pressure, this method has high requirements for high-pressure pumps, high-pressure pipe fittings and related high-pressure spare parts, and the price of spare parts is very high; the requirements for water are very strict, and the water must be softened and filtered before use; the nozzles are also required to be very hard Wear-resistant, the nozzles are generally made of gems or diamonds, and the life of each nozzle is 100-150 hours, so the cost of use is very expensive
