Vacuum welding equipment with interlayer for cooling and heating and application method of vacuum welding equipment

Abstract

The invention provides vacuum welding equipment with an interlayer for cooling and heating 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 a heat exchanging 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 sealing plate. 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 replaceable mode. The nitrogen making devicecan provide liquid nitrogen for a welding gun and a weldment for cooling. The heat exchanging device is connected to a vacuum chamber interlayer. Continuous production is achieved. The size of the vacuum chamber can be adjusted based on the size of the weldment. Welding technologies can be shifted. A welding smoke processing device is arranged, so that environment protection is achieved. The interlayer is arranged in the vacuum chamber. The interlayer is filled with heat conducting oil for cooling or heating. The requirements for temperatures of different welding technologies can be met.

Description

technical field [0001] The invention belongs to the technical field of vacuum welding, and relates to a vacuum welding device equipped with interlayer cooling and heating and a use method thereof. Background technique [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.

[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 carried out. The time of vacuuming seriously affects production efficiency. At the same time, the vacuum cannot be controlled during the process of welding different materials. room temperature environment, resulting in uneven welding quality; in addition, in the existing welding process, there is a need to switch to argon arc welding equipment for alternate welding operations, resulting in a large amount of smoke during the welding process, which seriously affects the welding quality of the welded parts and personnel health
