The advantages that quick molding method is due to quick, flexible, convenience is prepared in material and forming field has obtained extensively
Using.Especially in metal preparation field, due to that can save the complicated processes such as traditional casting, forging and stamping, realization can it is quick, low into
This preparation, has been obtained widely used in small lot, flexibility preparation field.
Existing rapid shaping prepares metal parts technology and generally melts powder or silk material online using the thermal source of movement,
And moving freely for three dimensions is realized by computer control system, so as to realize rapid shaping and manufacture, produce metal
Part is in kind.But this method has obtained molding part and generally required by offline inspection internal soundness, such as stomata, segregation, pit
Deng, and whether the index such as consistency meet the specification.Once it was found that internal soundness problem, then can not make up, can only sentence it is useless,
This brings challenge to the industrial applications of the technology.
Industry is currently needed for that online quality control can be realized and according to quality measurements, and can eliminate internal matter
The rapid shaping technique of amount problem, so as to promote industrial applications, but make little progress so far.
The content of the invention
It is an object of the invention to the quick molding method for possessing online quality control, quality is corrected, and solves traditional fast
The fast forming method offline quality testing cycle is long and technology that unrepairable can only be scrapped the defects of offline inspection is brought is difficult
Topic.
For achieving the above object, the present invention adopts the following technical scheme that：
Rapid shaping prepares metal parts method and device, and its operation principle is to be molded technique of the preparation system 1 according to input
Parameter prepared successively or by the metal in road, and heat power supply device 11 produces the thermal source such as laser beam or electric arc 13, then melting appartus
The metal dust or silk material of 12 fillings, while detection means 14 carries out quality inspection.Pass through temperature measuring equipment 2 and side thickness device 3
After detection, index is sent to control system 5, while instruction device 4 is rolled according to the parameter of setting.
The device includes shaping preparation system 1, temperature measuring equipment 2, side thickness device 3, rolling device 4, computer and programme-control
System 5.Preparation system 1 is molded, specifically includes laser or arc generating device 11, feeds silk or dust feeder 12, laser beam or electricity
The thermals source such as arc 13, quality detecting system 14, and shaping welding bead 15.Rolling device 4, specifically include working roll 41, support meanss
42, transmission device 43, hydraulic means 44.
Rapid shaping prepares metal parts method and device, when preparing nickel-base alloy, aluminum alloy materials, when implementing rolling
Roller surface shape should select concave surface.
Technology is described as follows：
By control system can molding preparation system 1 technological parameter, carry out successively or by road metal prepare.Thermal source fills
Putting 11 generations can the thermal source 13 such as laser beam, electric arc, plasma.Control system can be sent according to program setting command device 12
Powder or wire feed.According to the species and size of target material, thermal source 13 is coordinated with material input 12, so as to obtain metal target
It is prepared by part.
Then, quality inspection is carried out to the metal of foregoing preparation using detection means 14, it is the internal stomata of emphasis monitoring, thin
The internal flaws such as pine, and consistency is calculated, and will be to data feedback to quality control system 5, while quality system 5 can contrast
Internal database and quality criteria requirements.
Temperature measuring equipment can determine forming part surface temperature and feed back to control system.
Measuring thickness device can determine thickness and surface thickness difference and feed back to control system.
Control system can be according to qualitative data, temperature data, the thickness data received, and inputs its internal calculation mould
Type, and according to built-in system database result of calculation, rolling technology parameter is provided, and feed back to rolling device 4 in time.
Rolling device 4 according to instruction, can match surface configuration, drafts and the rolling temperatures scope of roll, so as to really
Internal soundness, surface configuration, the physical dimension protected after rolling.
Repacking is put including including being molded preparation system 1, temperature measuring equipment 2, side thickness device 3, rolling device 4, computer and program
Control system 5.Preparation system 1 is molded, specifically includes laser or arc generating device 11, feeds silk or dust feeder 12, laser beam
Or the thermal source such as electric arc 13, quality detecting system 14, and shaping welding bead 15.Rolling device 4, working roll 41 is specifically included, supported
Device 42, transmission device 43, hydraulic means 44.
When preparing nickel-base alloy, aluminum alloy materials, roller surface shape when implementing rolling should select concave surface, because this
Class material easily generates the internal flaw such as stomata, loose in rapid shaping, can be effective when being rolled using the roll of concave surface
Internal flaw is eliminated, and improves profiled part consistency.
Advantages of the present invention and beneficial effect：
Present approach provides the rapid shaping metal parts method and dress for being equipped with online quality control, online quality improvement
Put, quality testing can only be carried out offline and sentence technical barrier and bottleneck that time part can not be repaired by solving prior art.
