Problems solved by technology

As an important part of additive manufacturing technology, metal additive manufacturing mainly uses metal powder, granules or metal wire as raw materials. If the particle size of metal powder is too small, the problem of flying metal powder is serious, which is not conducive to the recovery of metal powder

Abstract

A powder recovery device of metal additive manufacturing equipment comprises a box. A box cover is arranged on the upper portion of the box, a first supporting frame is mounted at the bottom of the box, and a feeding hopper is arranged inside the box and located in the middle of the box; a feeding inlet is formed in the upper end of the feeding hopper, the upper end of the feeding inlet can penetrate through the box cover to be located outside, and a first discharging outlet is formed in the lower end of the feeding hopper; and an atomizing bin and a floating-down bin are arranged inside the box, and the floating-down bin is located at the bottom of the atomizing bin. First electromagnets are mounted in dust suction covers, and the first electromagnets are powered on so that metal powder can penetrate through through holes to enter the dust suction covers, and after stopping for a period of time, a control device controls a driving motor to rotate; the first electromagnets are poweredoff, and second electromagnets are powered on so that the metal powder can enter dust-removing cloth bags and can rapidly arrive at the lower ends of the dust-removing cloth bags under the attractionforce of the second electromagnets, meanwhile, second knocking rods knock the dust-removing cloth bags, thus the situation that the metal powder is pasted to the inner walls of the dust-removing clothbags is avoided, and the collecting speed is increased.

Description

technical field [0001] The invention belongs to the field of additive manufacturing equipment, in particular to a powder recovery device for metal additive manufacturing equipment. Background technique [0002] Additive manufacturing technology, born in the late 1980s, is a rapid prototyping process based on the principle of material accumulation. It is based on digital model files, using non-metallic bonding materials such as powdered metal or plastic, through layer-by-layer accumulation. The technology of constructing objects in a unique way has the characteristics of not being limited by the complexity of parts and fully digitalized control. As an important part of additive manufacturing technology, metal additive manufacturing mainly uses metal powder, granules or wire as raw materials. If the particle size of metal powder is too small, the problem of flying metal powder is serious, which is not conducive to the recovery of metal powder. Contents of the invention [0...
