Description
Technical Field
The utility model belongs to the technical field of welding equipment, concretely relates to very heavy uide bushing seal groove face metallic film welding equipment of hydraulic pressure.
Background
The guide sleeve used on the existing hydraulic jack is formed by carbon steel forging, the outer wall and the inner wall are respectively provided with a sealing groove, and a sealing original piece is arranged through the sealing groove to seal hydraulic pressure. The guide sleeve is a core stressed component of the hydraulic jack, due to the fact that the underground working environment is severe and the corrosion conditions of water quality of all parts are different, the hydraulic jack, particularly the guide sleeve, is often corroded and damaged to different degrees in the using process, particularly once the sealing groove surface is corroded and damaged to reach a certain limit value, pressure is relieved, and therefore the hydraulic jack is made to lose efficacy, and the solution mode can only be to replace a new guide sleeve. The service life of the existing guide sleeve on the market is about one year, the price is about 10 ten thousand yuan/ton, and each large enterprise frequently using hydraulic jack equipment has very large consumption of the guide sleeve every year, the equipment maintenance cost is seriously improved, the number of the guide sleeves which are disassembled and replaced is huge, the guide sleeves cannot be reused, and the guide sleeves can only be treated as scrap iron and are extremely serious in waste.
In order to prolong the service life of the guide sleeve, the technical means adopted at present is to increase a layer of metal film on the surface of the guide sleeve sealing groove by using an electroplating method so as to improve the corrosion resistance strength and the wear resistance strength of the surface of the guide sleeve sealing groove, but the metal film electroplated on the surface of the guide sleeve sealing groove by using the electroplating method can only be a single metal material and is only a few microns thick, and the service life is not obviously prolonged. The repair of the scrapped guide sleeve is mainly realized by turning a seal groove and increasing the seal at present, but the repair range has certain limitation, and the guide sleeve is only suitable for repairing with slight rust amount, and the repair process is complex, high in difficulty and poor in quality.
Aiming at the problems, a good theoretical scheme is adopted before, a layer of composite metal film is welded on the sealing groove surface of the guide sleeve, and composite metal (such as copper alloy, nickel alloy and the like) can greatly improve the corrosion resistance and the wear resistance of the sealing groove surface, so that the composite metal film has remarkable superiority, the service life of the composite metal film can be predicted to be greatly improved, but the existing welding technology cannot be realized, and the difficulty lies in that: firstly, a welding surface generates a large amount of bubbles, slag inclusion and other defects in the welding process, so that the sealing groove surface cannot be used; secondly, the guide sleeve is easily heated and deformed due to overhigh temperature in the welding process, so that the guide sleeve cannot be used; thirdly, because the uide bushing seal groove is mostly the right angle groove, the even roughness of the face of weld can't be guaranteed to current welding equipment, causes the welding groove face to be unable to use. If the technology of welding a layer of composite metal film on the sealing groove surface of the guide sleeve can be realized, the scrapped guide sleeve can be repaired by turning the sealing groove surface and then welding a layer of composite metal film in a repair mode, so that the service life of the guide sleeve is prolonged, waste recycling can be realized, and the effects of energy conservation and environmental protection are achieved.
