Abstract

The invention discloses a high-energy beam additive manufacturing forming device and method. The device comprises a magnetic field unit for assisting additive forming, and further comprises a formingbase for placing a to-be-processed material, and a high-energy beam generation device which emits a high-energy beam, acts on the to-be-processed material, and forms a molten pool. The magnetic fieldunit comprises a first magnetic field generating device, and the first magnetic field generating device comprises an induction coil arranged below the molten pool. The first magnetic field generatingdevice is detachably arranged below the surface, used for containing the to-be-processed material, of the forming base; a second magnetic field generating device is arranged above the forming base; the induction coil is arranged below the molten pool, and the molten pool is located in the area, where the clustered magnetic induction lines are emitted, of the induction coil, so that the clustered magnetic induction lines penetrate through the molten pool, therefore, the magnetic field intensity of the molten pool is concentrated, the control effect of the magnetic field on additive forming is improved, and the control efficiency of the magnetic field unit on the molten pool is improved.

Description

technical field

[0001] The invention relates to the field of metal additive manufacturing process control, in particular to a high-energy beam additive manufacturing molding device and molding method. Background technique

[0002] Additive manufacturing technology, also known as 3D printing technology, is based on the principle of layering and superposition, using computers to control the trajectory of high-energy laser beams / electron beams / arcs, and using high-energy laser beams / electron beams / arcs to melt metal powder. After the high-energy beam melts the metal powder, the molten metal forming the molten pool undergoes rapid cooling and solidification. The entire additive manufacturing is the forming step of the high-energy beam spot movement from point to surface, and then from surface to body. This point-line-surface-body integrated processing method has unique advantages in manufacturing components with complex shapes. Due to its high material utilization rate, short ...
