Abstract

The invention discloses a powder feeding control and recovery device. The powder feeding control and recovery device comprises a powder feeding device, wherein the discharge end of the powder feedingdevice communicates with a laser cladding operation end through a powder feeding pipe; a powder storage assembly is connected between the powder feeding pipe and the discharge end of the powder feeding device; the powder storage assembly comprises a powder inlet pipe, a reversing valve, a powder outlet pipe and a powder storage tank which are sequentially communicated; the reversing valve is a two-position three-way reversing valve; the feed end of the reversing valve communicates with the discharge end of the powder feeding device through the powder inlet pipe; the first discharge end of thereversing valve communicates with one end, far away from the laser cladding operation end, of the powder feeding pipe; and the second discharge end of the reversing valve communicates with the feed end of the powder storage tank through the powder outlet pipe. According to the powder feeding control and recovery device, the powder stabilization reservation time is avoided, the time cost is reduced, and real-time control is realized; powder in the powder storage tank can be fed back to the powder feeding device for cladding welding operation, so that powder waste is prevented, and the raw material cost is reduced; and the stability of the powder conveying amount is guaranteed, and the adverse effect of processing suspension on the powder stability is eliminated.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a powder feeding control and recovery device. Background technique [0002] Additive manufacturing technology refers to the "printing" of powder materials on the surface of objects to form the required surface layer or directly form the desired object, such as 3D printing, cladding equipment, etc. On the related equipment of additive manufacturing, it is necessary to use the powder bucket to load the printing powder required for printing to facilitate subsequent printing operations. [0003] In the welding and laser additive manufacturing system, the powder is delivered to the operation end through the powder feeding device, that is, the cladding head of the laser cladding welding equipment, and the powder amount can be adjusted through the powder feeding device as needed. During welding or laser processing, it is not continuous, and there is often a pause in the ...
