Abstract

The invention discloses a hollow metal material preparing device which comprises a workbench and a fixing frame. The fixing frame is composed of stand columns and a first beam provided with a throughhole and a plug pin. A magnetic stirring water bath pot and a slurry container are arranged in an inner cavity of the fixing frame. A dipping basket is arranged in the slurry container. The dipping basket comprises a basket frame, a porous base plate and a porous cover plate. The two sides of the basket frame are connected with a first lifting rod and a second lifting rod connected with a second beam separately. A third lifting rod is connected to the porous cover plate. The invention further discloses a hollow metal material preparing method. According to the method, after an inner supportingbody is pretreated and then dipped in metal powder slurry, then, sintering is performed, and a hollow metal material is obtained. The phenomenon that the inner supporting body floats in the slurry isavoided through the dipping basket, the defect that residual falling, rolling and secondary contamination of the inner supporting body appear is avoided, batched production is achieved, and the prepared hollow metal material has the advantages of being high in void ratio, high in strength and low in mass.

Description

technical field [0001] The invention belongs to the technical field of metal material preparation, and in particular relates to a preparation device and method of a hollow metal material. Background technique [0002] Hollow metal porous composite material is a new type of porous material developed in recent years. It has the characteristics of light weight, good impact resistance and high energy absorption performance. It has great application prospects. At present, the preparation of hollow metal porous composite materials mostly uses spherical cores such as glass microspheres, spherical sodium chloride particles, polyurethane foam, and ceramics to make a hollow metal porous composite material with a sandwich structure. The obtained hollow metal The hollow-shaped pores in the internal structure of porous composite materials cannot be well distributed. During the preparation process, some support materials whose internal filling substances cannot be removed limit the applic...
