Abstract

The invention belongs to the welding field, in particular to an intelligent magnetic shielding device for electron beam welding. The device includes a detection unit, a shield part and a control part,The structure of the shielding cover can be adjusted according to the complexity of the electron beam machining and the intensity of the ambient magnetic field, and the expansion and contraction of the electric ejector rod can be controlled to make the inner and outer silicon steel sheets be nested and combined into a single-layer structure or a multi-layer structure, so as to realize different shielding requirements, thereby ensuring stable track and high welding precision when the electron beam machining is carried out.

Description

technical field [0001] The invention belongs to the field of welding, in particular to an intelligent magnetic shielding device for electron beam welding. Background technique [0002] The electron beam welding technology of one gun and multiple beams is to make the electron beams move rapidly at different positions through the control of the magnetic field. Due to the high frequency of movement, the effect of multiple beams is generated, so as to process and process the material or structure. Vacuum electron beam welding has extremely strict requirements on the magnetic field, and the moving charge will be disturbed by the environmental magnetic field or the magnetic field of the workpiece, and the trajectory will be deflected. The patent CN105228433A of Xi'an Aviation Power Co., Ltd. provides a magnetic field shielding method, but this method is only suitable for single-beam electron beam processing. Contents of the invention [0003] The invention provides an intellige...
