Obtain rolled-up stock；Or pressurize 1-3min obtains rolled-up stock under hot pressing pressure 300-400MPa；
5) dissolve pore creating material, by step 4) rolled-up stock be placed in pore creating material dissolving tank, the water temperature of pore creating material dissolving tank is adjusted to
30-50 DEG C, sonic oscillation is completely dissolved to pore creating material, takes out rolled-up stock and stands；
6) it being dried rolled-up stock, by step 5) rolled-up stock of gained puts in air dry oven and takes out after drying；
7) sintering rolled-up stock, puts in holding furnace by dried rolled-up stock, is warming up to the programming rate of 5-10 DEG C/min
500-550 DEG C, it is incubated 0.5-1h；If step 1) in material choice be pure magnesium or magnesium alloy powder, need first logical in holding furnace
Enter protective gas 10-20min, then heat up；
8) cooling, is put in cooling pond cooling by the rolled-up stock after sintering, puts in air dry oven and dry, i.e. after cooling
Obtain open cell foam metal.
Compared with prior art, the invention has the beneficial effects as follows:
Complete set of equipments of the present invention has outstanding feature and marked improvement in the following areas:
(1) complete equipment uses the design concept of three district's distributions of upper, middle and lower three-decker and left, center, right, improves the profit in space
By rate, reduce cost of investment.
(2) single robot device can realize rolled-up stock in liftout attachment, pore creating material dissolving tank, air dry oven, insulation
Branch problem between stove, cooling pond, process can realize mechanization, save labor cost.
(3) design of the back-shaped transporter of mould, realizes recycling mould by transporter controller, improves mould
The utilization rate of tool；The transmission of mould uses roller bearing conveying and station to control, and each station sets pin type touching switch to control mould
The operation of tool, decreases manual operation, improves efficiency and safety.
(4) raw material by mix powder machine falls into mould occurs in the middle of material many, around expect few phenomenon, by the vibration of agitator
Make raw material be distributed in whole mould more uniform, preferably ensure the concordance of rolled-up stock performance, reduce because periphery lacks material pressure not
Obtain underproof rolled-up stock in fact.
(5) in the course of dissolution of pore creating material, by controlling the outlet with regulation valve and water inlet, pore creating material is made to dissolve
Water in pond keeps flowing, accelerates the dissolving of pore creating material Sal granule；By adding dissolving tank heater, circulating water is heated,
Improve Sal granule dissolubility in water；Ultrasonator vibrational flow water bottom pore creating material dissolving tank, further speeds up food
The dissolving of salt；Course of dissolution does not use alkali liquor be carried out, decrease the corrosion to foamed aluminium；This pore creating material dissolving tank both saved
Energy environmental protection, reduces again cost, and safety simple to operate.
(6) leakage basket uses the design of multiple small grid, can dissolve different batches pressed blanks in n little leakage basket simultaneously
Sal granule (is put with a batch of rolled-up stock in each leakage basket), substantially increases production efficiency.
(7) holding furnace, the use of mating protection gas, also can produce oxidizable or incendive foam metal (such as, bubble
Foam magnesium alloy etc.).
(8) mixed powder machine uses the mixed powder tank of n same model carry out mixed powder simultaneously, improve productivity ratio；Use phase homotype
Number mixed powder tank preferably ensure in identical mixed powder speed with under the time, the powder in n mixed powder tank reaches uniform simultaneously.
(9) mould may be designed to the structure of a multi-cavity mold, and once compacting obtains multiple rolled-up stock, not only improves productivity ratio but also subtract
Lack the abrasion of pressure apparatus.
The marked improvement of the inventive method is:
(1) replacing carbamide conventional in powder metallurgic method to do pore creating material with Sal granule, Sal aboundresources is easy to get, recyclable
Utilize, both saved cost, again safety non-pollution；Sal may select spherical, cube shaped, irregular shape, according to actual need
The Open-cell Aluminum Foam of Different Pore Structures to be obtained.
(2) solvent of pore creating material uses clear water to replace alcohol and the alkali liquor of sodium hydroxide preparation, has both reduced foamed aluminium/foam magnesium
Corrosion, saved again cost.
(3) first aluminium powder being ground removing surface film oxide during the most mixed powder, strengthening the adhesion between aluminium powder preferably to press
Real rolled-up stock；First with low speed (250-300r/min) mixing a period of time (20-30min), then adjust increasing to height speed
(350-450r/min) mixing a period of time, so make mixing the most uniform.
(4) during rolled-up stock sintering, holding furnace is to slowly warm up to 500-550 DEG C with the speed of 5-10 DEG C/min, controls programming rate,
Selecting slowly heats up makes rolled-up stock internal/external heating more uniform, reduces the defects such as the cracking because internal-external temperature difference causes, deformation.

If rolled-up stock is less in the present invention, mould 203 can use the design of a multi-cavity mold, should make top board 206 into push rod, one
The corresponding one or more push rods of individual rolled-up stock.Mixed powder tank 104 carries out rotation while revolving round the sun with traffic cycle 101, utilizes operating to produce
The centrifugal force of life, frictional force, abrading-ball moves in mixed powder tank 104 and is ground mixed powder；Abrading-ball select rustless steel, diameter according to
Required powder size selects；The diameter of mixed powder tank material spilling hole can not be excessive, postpones in case weight induction device 202 display regards number
The raw materials quality in mould 203 is caused to count more than regarding of weight induction device 202 display.In the application, n is natural number.
The present invention prepares the method (abbreviation method) of open cell foam metal, uses above-mentioned complete set of equipments, comprises the following steps:
1) select materials, select spherical, cube shaped or irregular shape, and the Sal granule of a diameter of 1-5mm is pore creating material, choosing
Selecting raw material is the fine aluminium of a diameter of 100-300 μm, aluminium alloy, pure magnesium or magnesium alloy powder；
2) powder is uniformly mixed, by raw material speed grinding 20-30min with 150-200r/min in mixed powder machine；According to Sal granule
It is that 0.05-0.10 weighs Sal granule with the mass ratio of raw material, after mixing 20-40min with the speed of 250-300r/min, by speed
Degree increases to 350-450r/min, the powder being uniformly mixed after mixing 20-30min；
3) charging, by step 2) powder of mix homogeneously is blown in mould by aerator, vibrates, make powder divide in a mold
Cloth is the most uniform；
4) compacting, is sent to compressing district by the mould installing powder, pressurize 2-4min under the pressure 500-600MPa that colds pressing
Obtain rolled-up stock；Or pressurize 1-3min obtains rolled-up stock under hot pressing pressure 300-400MPa；
5) dissolve pore creating material, by step 4) rolled-up stock be placed in pore creating material dissolving tank, the water temperature of pore creating material dissolving tank is adjusted to
30-50 DEG C, sonic oscillation is completely dissolved to pore creating material, takes out rolled-up stock and stands；
6) it being dried rolled-up stock, by step 5) rolled-up stock of gained puts in air dry oven and takes out after drying；
7) sintering rolled-up stock, puts in holding furnace by dried rolled-up stock, is warming up to the programming rate of 5-10 DEG C/min
500-550 DEG C, it is incubated 0.5-1h；If step 1) in material choice be pure magnesium or magnesium alloy powder, need first logical in holding furnace
Enter protective gas 10-20min, then heat up；
8) cooling, is put in cooling pond cooling by the rolled-up stock after sintering, puts in air dry oven and dry, i.e. after cooling
Obtain open cell foam metal.
The inventive method is further characterized by described step 8) open celled foam can be obtained to use cool down in the way of furnace cooling
Metal, if open celled foam magnesium, should be carried out during furnace cooling under protection gas.
