Abstract

The invention relates to a pressure-buffering foaming device, which includes a sealed foaming chamber and a foaming pipe for introducing foaming gas, including: a pressure booster plate, a first pressure relief groove and a second pressure relief groove. The pressure plate is installed on the foaming tube with sliding fit, and is arranged in sealing cooperation with the inner wall of the foaming chamber. The upper and lower sides respectively form a pressure relief area and a pressurization area. The first pressure relief groove is set on one side of the inner wall of the foaming chamber , and located above the booster plate, the second pressure relief groove is set opposite to the first pressure relief groove and located above it; by changing the position of the waste gas discharge port, the flow direction of the foaming gas inside the melt can be changed, and the gas flow direction can be changed During the process, the foaming gas flows through the foaming blind area and at the same time, the melt in the foaming blind area is foamed, so as to solve the technical problem of low foaming rate in the foaming blind area in the prior art.

Description

technical field [0001] The invention relates to the technical field of foaming aluminum production equipment, in particular to a pressure-buffering foaming device. 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 world materials science research; such as figure 1 As shown, during the foaming process of foamed aluminum, due to the positional relationship of the exhaust gas outlet after foaming, the foaming rate of the melt in ...
