Research and Development of Vacuum Electron Beam Cladding Equipment
Focusing on the strategic requirements of vacuum electron beam cladding equipment and the research and devel-opment of core functional components.Study on key technologies such as electron beam gun technology,mechanical mo-tion mechanism and control technology,and vacuum quantitative powder feeding technology.The electron beam cladding equipment consists of an electron beam gun system,mechanical motion and control system,vacuum system,vacuum pow-der feeding system,monitoring system,PLC control system,etc.Develop an electron beam gun with a plasma hollow cath-ode structure to achieve normal operation of the electron beam under low vacuum conditions.The continuous working time of the cathode can exceed 50 hours,making it suitable for electron beam cladding and additive manufacturing.Optimize the design of the electromagnetic focusing system by adjusting the magnetic field distribution to control the focusing degree of the electron beam.The focusing system ensures good focusing current stability of the electron beam,and the deviation of the measured focusing current from the set value is≤0.5%.Research and Development of the five axis linkage motion mecha-nism and numerical control system,which enables the fusion and additive manufacturing of complex spatial surfaces.Stud-ied the vacuum pumping and vacuum powder feeding system to achieve continuous and controllable powder feeding.Inte-grate electronic guns,vacuum systems,motion systems,etc.with the control system through PLC control system for overall debugging and optimization.Resolve compatibility and stability issues that may arise during system operation.The break-through in the above-mentioned key technologies is a necessary condition for the localization and integrated manufacturing of electron beam cladding equipment.
