Apparatus for adjusting the powder flow in relation to the central axis of the energy beam

摘要

DeviceA device for aligning the powder feed in two dimensionsIt is provided on the machining headElectromagnetic radiation started from radiation sourceThe particle of the powdered material is directed to the region (3) to which it is joined as a linear beamThe photodetector arrayThe intensity of electromagnetic radiation is designed to be spatially resolved and capturedConnected to the electronic evaluation unit (8);The electronic evaluation sectionThe shape of the irradiated region (9) captured by the photodetector array (7) with intensity exceeding the acceptable thresholdSize and / or lengthDesigned to be confirmed in a spatially resolved mannerThe irradiated regionFrom the particle surface of the powder irradiated with the reduced power laser beam 4 during adjustmentLocated in the direction of the powder particle accelerated toward the surface of the workpieceThe particles heated by the laser beam (4) extend to the partial region of the irradiated region (9) which is diversibly moved.Diagram
