The cylinder metal foam welding procedure that fruit impacts, with overcome the deficiencies in the prior art.
A purpose of the invention is achieved in that
A kind of cylinder metal foam welding procedure, it is characterised in that: the first step, metal foam sheets are round as a ball, it forms band and opens
Mouthful cylindrical shape, opening requirement cleans out, impulse- free robustness, smooth surface (after carrying out above-mentioned processing to open surfaces, can
So that opening close up it is even closer), and it is round as a ball after metal foam sheets when being disposed vertically, opening contact surface can close naturally
Hold together.
Second step is equipped at least two shallow slots along the axis direction of cylindrical metal cystosepiment is spaced apart, each shallow
Slot straight line arranges and installs copper wire clamp in the opening of cylindrical metal cystosepiment, shallow slot；Copper wire clamp is embedded into shallow slot,
Opening is avoided to open.
Third step handles the burr in cylindrical metal cystosepiment, and keeps it internal in smooth；
Opening is connected and fixed by the 4th step by the way of 3D printing metal powder, and 3D printing metal powder can be by copper wire clamp
It covers.
5th step naturally cools to room temperature after 3D printing metal powder, so that 3D printing metal bisque keeps preferable toughness,
It avoids that 3D printing metal bisque is made to become fragile because of rapid cooling, is easy to cause cracking.
6th step, the seam crossing of polishing connection opening simultaneously carries out sanding processing to it, with increasing friction force.
7th step, the processing of spray protective layer, since the 6th step carries out sanding processing to it, can make protective layer at abutment joint
There is better adhesive force with it.
8th step is blown clean cylindrical metal foam plate surface and intrapore impurity using high pressure air rifle, to make
It obtains its internal porous structure to exist, also, avoids the heat exchange of impurity effect metal foam surface and air.
A purpose of the invention can also be solved using following technical measures:
As more specific scheme, the round as a ball front surface of metal foam sheets passes through roughening treatment, during roughening treatment, first
Be metal foam sheets substrate surface treatment is clean, metal wire rod is sprayed on metal foam surface using machine.
As further embodiment, metal wire rod be aluminium wire, stainless steel wire or copper wire (but not limiting to the above different materials),
A diameter of 1.5mm to 2.0mm.
As further embodiment, between adjacent two shallow slot between be divided into 60mm to 100mm.
As further embodiment, copper wire clamp is U-shaped, and copper wire clamp diameter is 2.0mm to 3.0mm.
As further embodiment, the print temperature of 3D printing metal powder is 400 DEG C to 500 DEG C；Print speed is 3mm/s
To 6 mm/s.
As further embodiment, seam crossing spray protective layer sprays to be formed using metal wire rod, and width is 45 mm to 50
mm。
Metal foam sheets that are easy, promoting metal foam heat dissipation effect are produced another object of the present invention is to provide a kind of
Roughening process, with overcome the deficiencies in the prior art.
It is another object of the present invention to what is be achieved:
A kind of metal foam sheets roughening process, it is characterised in that: be first metal foam sheets substrate surface treatment is clean,
Metal wire rod is sprayed on metal foam surface using machine.Wherein, the machine of spraying metal materials requires to be that treatment effeciency is high, right
Foam metal penetration power is strong.
Another object of the present invention can also be solved using following technical measures:
As more specific scheme, metal wire rod is aluminium wire, stainless steel wire or copper wire (but not limiting to the above different materials).
Metal wire rod diameter is 1.5mm to 2.0mm.
Beneficial effects of the present invention are as follows:
(1) opening of cylinder metal foam of the invention is welded and fixed in a manner of 3D printing metal powder, and metal powder will not
The porous structure for blocking metal foaming material makes it keep original porous heat sinking function, the cylinder metal foam with the prior art
Foam is compared, better heat-radiation effect；
(2) metal foam sheets of the invention increase metal foam structures surface area by roughening treatment, greatly promote it and dissipate
Thermal effect；Moreover, because its rough surface, adhesive force is strong, convenient for being welded by 3D printing metal powder to it.
