Abstract

The invention belongs to the field of welding and particularly relates to a one-gun multi-beam electron beam welding anti-magnetic-interference device. The one-gun multi-beam electron beam welding anti-magnetic-interference device comprises a detection part, a shielding part and a control part. With the adoption of the one-gun multi-beam electron beam welding anti-magnetic-interference device, a structure of a shielding case can be adjusted according to the complexity degree of electronic beam machining and the intensity of an environmental magnetic field, and an electric push rod is controlled to extend and retractso as to allow silicon steel sheets on the inner layers and the outer layers to be nested and combined into a single-layer structure or a multi-layer structure, so that the different shielding requirements are achieved, it is guaranteed that the track is stable in the electronic beam machining process, and the welding accuracy is high.

Description

Technical field [0001] The invention belongs to the field of welding, and particularly relates to an antimagnetic interference device for electron beam welding. Background technique [0002] The one-shot multi-beam electron beam welding technology makes the electron beam move quickly in different positions through the control of the magnetic field, and the effect of multiple beams is produced due to the high frequency of the movement, thereby processing and processing the material or structure. Vacuum electron beam welding has very strict requirements on the magnetic field, and the moving charge will deviate from the trajectory due to the interference of the environmental magnetic field or the magnetic field of the workpiece. The patent CN105228433A of Xi'an Aerodynamics Co., Ltd. provides a magnetic field shielding method, but this method is only suitable for single beam electron beam processing. Summary of the invention [0003] The invention provides a magnetic interference sh...
