Vacuum welding equipment with supersonic aging function and application method of vacuum welding equipment

Abstract

The invention provides vacuum welding equipment with an supersonic aging function and an application method of the vacuum welding equipment. The vacuum welding equipment comprises a vacuum device, a welding vacuum chamber, a feeding vacuum chamber, an electron beam welding device, a welding working table, an argon arc welding device, a nitrogen making device, and an supersonic aging device. The welding vacuum chamber and the feeding vacuum chamber are separately provided with a piston sealing plate and a lifting sealing plate. The electron beam welding device is arranged on the piston sealingplate. The welding working table can rotate at 180 degrees and 360 degrees. The argon arc welding device is mounted on the piston sealing plate in a replacing mode. The nitrogen making device can provide liquid nitrogen for a welding gun and a weldment for cooling. The supersonic aging device is arranged on a conveying belt. Continuous production is achieved. The size of the vacuum chamber can beadjusted based on the size of the weldment. Impurities of the weldment can be shaken off before the weldment entering the vacuum chamber. The supersonic aging is adopted to remove welding stress afterwelding. The fatigue life of a welding structure is prolonged. The welding quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of vacuum welding, and relates to a vacuum welding device with an ultrasonic aging function and a use method thereof. Background technique [0002] In the existing welding equipment, there are many technologies such as explosive welding and vacuum welding.

[0002] In the existing welding equipment, there are many technologies such as explosive welding and vacuum welding. Among them, vacuum electron beam welding is the welding of materials in a vacuum environment. Electron beams can weld different metals and alloy materials, especially high refractory metals. Welding, and the welding precision is high, the efficiency of welding large and thick parts is higher, the welded joints are of high purity, the weld seam is pure, smooth, mirror-like, and free of oxidation and other defects; but at present, due to the long vacuuming time of large-scale vacuum electron beam welding, about It takes 10-15 minutes, and repeated vacuuming is required for each welding, which affects the production efficiency of the equipment. Especially when welding small parts, continuous welding cannot be performed, and the vacuuming time seriously affects production efficiency; at the same time, welding stress will be generated during welding, resulting in welding In addition, in the existing welding process, there is a need to switch to argon arc welding equipment for alternate welding operations, causing a lot of smoke during the welding process, which seriously affects the welding quality of the welded parts and the health of personnel
