Shell of the present invention comprises end cap and housing, and case body is rectangular tube or pipe.
The preparation method of metallic honeycomb sandwich assembly energy-absorbing construction material, this method comprises following content:
A. metal plate cold-bent is pressed into half regular hexagon corrugated sheet, half regular hexagon corrugated sheet is buckled together again, forming end face is cellular metallic honeycomb sandwich body;
B. dividing plate is selected the cold rolled metal thin plate for use;
C. shell adds the sheetmetal end cap by common metal thin-walled square tube or pipe and makes;
D. utilize conventional acid or alkaline cleaner clean metal end cap, metal shell, metal partion (metp), metallic honeycomb sandwich body;
E. with 1～4 mutual crisscross combination of metallic honeycomb sandwich body, add metal partion (metp) between the every metallic honeycomb sandwich body, the metal brazing filler metal is folded up between metal end, metal shell, metal partion (metp), metallic honeycomb sandwich body, and with the combination the metallic honeycomb sandwich body place in the metal shell, seal up with end cap at two ends, uses the metal end at clamp two ends then;
F. place in vacuum furnace or the atmosphere furnace, cold conditions is evacuated down to 1 * 10
-1～1 * 10
-2Pa is above or charge into Ar or N
2Shielding gas is heated to brazing temperature, is incubated 20～50 minutes and carries out soldering, and take out the cooling back.
The present invention compared with prior art, its significant advantage is:
With the common metal thin plate is cellular structural material, and material source is extensive, and cost is low, and assembly energy-absorbing construction material promptly can be used as the welded structure bearing load, can be used as the buffering energy-absorbing parts again.The plasticity of metal and good toughness are clashed into back generation plastic yield and the plastic buckling distortion can absorb lot of energy, and after optimal design, its load to weight ratio and buffering efficient can reach more than 90%.This composite structure helps classification and absorbs impact energy, and for some varying load impact events, crisscross composite structure can be resisted the bump of different direction; Classification slows down bump stroke; Classification dissipation impact energy; Adopt soldering to connect the adhesive strength that can improve between each constituent element, each constituent element can only be out of shape with plastic yield and plastic buckling mode, prevent between each constituent element to produce the phenomenon that shearing is scattered because of adhesive strength is low.
