Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the present invention.But the present invention can be much different from alternate manner described here to implement, those skilled in the art can when without prejudice to doing similar improvement when intension of the present invention, therefore the present invention is by the restriction of following public concrete enforcement.
Refer to Fig. 1, the metal product 100 of an embodiment, it is applied in electronic installation.Metal product 100 comprises the first metal parts 10 and is welded in the second metal parts 30 on the first metal parts 10.First metal parts 10 and the second metal parts 30 are made by aluminum alloy materials.Be appreciated that metal product 100 also can be made for other metal materials such as magnesium alloys.
See also Fig. 2, a kind of metal product forming method, it comprises the following steps:
Step S101, provides the metal parts with position to be welded.In the present embodiment, first metal parts 10, second metal parts 30, first gummed paper 40 and the second gummed paper 50 is provided, first metal parts 10 is formed with the first position 15 to be welded, second metal parts 30 is formed with the second position 35 to be welded, the mating shapes at the first gummed paper 40 shape and the first position 15 to be welded, the mating shapes at the shape of the second gummed paper 50 and the second position 35 to be welded.
Step S102, blocks the position to be welded of metal parts; Particularly, the first gummed paper 40 and the second gummed paper 50 are pasted on respectively on the position to be welded 15,35 on the first metal parts 10 and the second metal parts 30, to block.Be appreciated that and other modes such as fixture blocks can also be adopted to realize blocking first and second position 15,35 to be welded, also can be pre-formed the structure of definite shape to cover on the welding position of metal parts.
Step S103, carries out anodized to metal parts; Particularly, it comprises the following steps:
(1) pre-treatment of metal parts; Carry out oil removing and activation to the first metal parts 10 and the second metal parts 30, oil removing adopts in the aqueous solution formed at concentration 5% ~ 15% NaOH and concentration 5 ~ 15% sodium phosphate to be carried out, and treatment temperature is room temperature, 20 ~ 60 seconds processing times; Activating process adopts and carries out in the aqueous solution of concentration 20% ~ 40%NaF, and treatment temperature is 20 ~ 60 DEG C, 3 ~ 15 minutes processing times.
(2) anodic oxidation solution is prepared; Anodic oxidation solution is made up of anodic oxidation base soln and Ludox, and the aqueous silicate solution that anodic oxidation base soln is 0.2 ~ 3.0 mol/L by concentration forms.Ludox addition volume ratio is 5 ~ 40% of anodic oxidation base soln, and Ludox is the colloidal sol with O-Si-O chain structure.
(3) anodized; Particularly, anodized adopts AC power or dc source.When adopting AC power, will through the first metal parts 10 of step (1) and the second metal parts 30 as anode, be placed in the anodic oxidation solution that step (2) prepares, solution temperature is 0 ~ 60 degree Celsius, current density is 5 ~ 30 milliamperes/square centimeter, and oxidization time is 10 ~ 60 minutes; When adopting dc source: first metal parts 10 that will process through step (1) and the second metal parts 30 are as anode, adopt corrosion resistant plate as negative electrode, be placed in the anodic oxidation solution that step (2) prepares, solution temperature is 0 ~ 60 degree Celsius, anodic current density is 5 ~ 30 milli case/square centimeters, and oxidization time is 10 ~ 40 minutes.
(4) take out metal parts and carry out rinsing and drying and processing.Namely the first metal parts 10 is taken out and the second metal parts 30 carries out rinsing and drying and processing.
Step S104, the position to be welded of exposing metal parts is also welded this position to be welded, to obtain metal product.In the present embodiment, remove gummed paper 105 on the first metal parts 10 and the second metal parts 30 to expose position 15,35 to be welded, second position 35 to be welded is aimed at and laser weld in the first position 15 to be welded, thus together with the first metal parts 10 is welded in the second metal parts 30.When adopting fixture to block, first need remove fixture and being appreciated that to carry out welding behind the position to be welded of exposing metal parts again.In addition, also can other modes such as substitute soldering, agitating friction welding weld.
Be appreciated that metal product 100 also only can comprise a metal parts, namely the first metal parts 10 and the second metal parts 30 one-body molded and its on only leave a position to be welded, as hole etc.Described metal product forming method is used for processing a described metal parts, namely carries out anodized to described metal parts and is eliminated by described hole by welding.
Before anodic oxidation is carried out to metal product 100, take the measure of blocking, the position to be welded 15,35 of metal parts 10,30 thoroughly can be avoided to occur anodic oxide coating, therefore, it is possible to reduce the impact of anodic oxide coating on welding to greatest extent, effectively improve intensity and the stability of welding.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
