Abstract

The invention discloses a variable gradient powder supply device for SLM gradient metal printing, which includes a stocker and a movable partition. The feeder has a plurality of evenly arranged powder supply compartments along its length direction. Each powder supply compartment is equipped with a movable partition along its length direction, and the movable partition is slidably connected to the corresponding powder supply compartment. Inside, it is used to separate each powder supply partition into two or more powder supply sub-slots; the controller is located outside the stocker, and the controller is connected with multiple movable partitions for controlling multiple movable partitions. The plates slide along the length of the corresponding powder supply compartment. The variable gradient powder supply device has simple structure, reasonable design, good flexibility and easy operation, can effectively improve the content accuracy of each component of the gradient material, and has a good market application prospect.

Description

technical field [0001] The invention relates to the technical field of powder supply devices, and more specifically relates to a variable gradient powder supply device for SLM gradient metal printing. Background technique [0002] Gradient materials are more and more favored by scientific researchers because of their adaptability to the development of high-tech. Selective laser melting technology SLM is an important method for preparing functionally gradient materials. Research on precise powder supply devices has become an important step in the preparation of high-performance gradient materials. important topic. At present, the existing powder supply devices all use a movable partition to divide the stocker to realize the adjustment of gradient powder supply components. The disadvantage is that the horizontal plane of the powder layer is always along the material composition gradient perpendicular to the powder spreading direction. Constant and less precise. [0003] Ther...
