Description

Technical Field

[0001] The invention relates to the technical field of welding devices, in particular to a medium-pressure vacuum electron beam welding device for blade welding. Background Art

[0002] Electron beam welding is a welding method that uses the heat energy generated by the bombardment of the weldment placed in a vacuum or non-vacuum by an accelerated and focused electron beam. Electron beam welding is widely used in many industries such as aerospace, atomic energy, national defense and military industry, automobiles, and electrical and electrical instruments because of its advantages of no need for welding rods, not easy to oxidize, good process repeatability, and small thermal deformation; every progress in electron beam welding technology has made human aviation manufacturing technology more perfect and robust. The high stability and high strength characteristics of electron beam technology have enabled aircraft metallurgy to have more advanced science and structural precision design. The important technology that exists today is actually to reduce hydrogen embrittlement and limit oxygen and hydrogen pollutants while reducing decomposition, heating, and residual stress. As an important technology in the field of welding integration, electron beam welding technology has now increasingly affected the manufacturing and design of aerospace aircraft.

[0003] Although ordinary electron beam welding can effectively limit oxygen and hydrogen pollutants, hydrogen pollutants still exist. The welding method of electron beam welding is to form a ray, which is harmful to the operator, so attention should be paid to protection at all times during welding.

[0004] The prior art discloses a vacuum electron beam welding device, which includes a vacuum space, a movable workbench is provided at the bottom of the inner cavity of the vacuum room, a vacuum system interface is fixedly installed at the bottom of the right side of the vacuum room, a glass mirror is fixedly installed at the middle of the left front end of the vacuum room, an electron beam gun is fixedly installed at the top of the vacuum room, and a filament power supply, a cathode, an anode, a focusing coil and a deflection coil are fixedly installed in the inner cavity of the electron beam gun from top to bottom in sequence, the movable workbench, the filament power supply, the cathode and the anode are all electrically connected to the high-voltage power supply, and the focusing coil is electrically connected to the focusing power supply. This vacuum electron beam welding device extracts the air inside the vacuum space from the vacuum system interface through the vacuum system device to form a real vacuum space, which can effectively reduce pollution, and does not require contact with the staff, so the health of the staff is guaranteed.

[0005] However, when the above-mentioned equipment performs electron beam welding, if the clamping effect of the welded parts is not good enough, the clamping is not stable enough or the clamping position deviates, it will lead to welding failure and affect the welding efficiency. In addition, during the electron beam welding operation, the temperature inside the welding chamber will rise, and there is a lack of corresponding cooling mechanism for cooling and heat dissipation. Excessive temperature will affect the welding process.
