Abstract

The invention relates to a compression-buffer composite foaming mechanism. The compression-buffer composite foaming mechanism comprises an accommodating bin, a foaming pipe, a foaming assembly and a pressurizing plate, wherein a pressure relief groove is formed in the inner wall of the accommodating bin which is used for storing a melt; a gas emission channel is formed between the pressure reliefgroove and the pressurizing plate; a foaming gas enters the bottom of the accommodating bin through the foaming pipe, and then is applied to the gas foaming of the melt; being driven by a driving assembly, the foaming assembly spirally pushes a solution positioned at the upper part of the melt to the bottom of the melt; the pressurizing plate is cooperatively mounted on the foaming pipe and in a movable seal fit with the inner wall of the accommodating bin; an emission zone and a gas storage zone are correspondingly formed on the upper and lower sides of the pressurizing plate; a sufficient amount of the foaming gas is adopted for the secondary foaming of the aluminum solution in the high-pressure state; meanwhile, the aluminum soliton and the gas which are positioned at the upper part ofthe melt are circularly transmitted to the bottom of the belt from top to bottom, thereby achieving the sufficient mixing and foaming of the foaming gas and the aluminum solution; and accordingly, thetechnical problems that in the prior art, the foaming effect is non-uniform and the foaming rate is low are solved.

Description

technical field [0001] The invention relates to the technical field of foamed aluminum production equipment, in particular to a compression buffer composite foaming mechanism. Background technique [0002] Metal foam is a new type of multi-purpose material. Commonly used porous metal materials include bronze, nickel, titanium, lead, stainless steel, and other metals and alloys. Among all porous metal materials, aluminum foam is the most widely used; its It has excellent mechanical damping, noise reduction, energy absorption, electromagnetic shielding and other functions, and is light, strong, heat-resistant and beautiful. It has broad application prospects in many fields such as national economic construction and national defense high-tech. One of the important contents of material science research in the world; however, during the foaming process of aluminum foam, there are bubbles generated by the foaming agent floating up, and the upper part of the melt has more pores tha...
