Abstract
The invention relates to a method of repairing a metal part through additive manufacturing. The method comprises the following steps of scanning by three-dimensional scanning equipment to obtain three-dimensional data of a worn part, then comparing the three-dimensional data of the worn part with that of an intact part through three-dimensional software, carrying out Boolean calculation, carrying out subtraction on the three-dimensional data to obtain three-dimensional data of worn portions of the part, then stacking the worn portions by virtue of a means of additive manufacturing, and finally, obtaining the intact part. According to the method, a wear value of the metal part can be accurately measured and the worn metal part can be rapidly repaired.
Description
Technical field
The present invention relates to a kind of method increasing material manufacture reparation metal parts.Referring more particularly to data acquisition after metallic element use is worn and torn, then these data and Complete three-dimensional data are contrasted, wearing part utilizes the mode increasing material manufacture to repair complete method the most at last.
Background technology
In plant equipment, the situation such as parts depreciation, scuffing and dimension overproof is recurrent, and these situations account for 70% that machine components lost efficacy.The parts great majority of equipment are metal material, owing to its intensity is high, hardness is big, and parts are in work running under the effect of impact vibrated and other composite force, frequently result in metal parts and produce " firmly to hard " relation, lengthening over time, part blastic deformation becomes permanent deformation, and recovery stress declines, crushed element can not recover, thus forming gap between part and part, it is impossible to meet the cooperation of service requirement, cause the component wear that hardness is relatively low.
The restorative procedure that wearing terrain is conventional has the techniques such as built-up welding, thermal spraying, brush cross, often because there is no the data of abrading section when carrying out these renovation techniques, I haven't seen you for ages is difficult to accurately grasp and control for repairing amount many, directly affect the dimensional accuracy after part is repaired and normal use, cause the cost repairing part far above the manufacture again of part.
Therefore, patent of the present invention first passes through 3-D scanning, the three-dimensional data of worn-out part is obtained after equipment component is scanned, then pass through three-dimensional software to contrast with complete parts three-dimensional data, again through the method that three-dimensional software carries out Boolean calculation, two data are subtracted each other the three-dimensional data obtaining having worn out part, piles up out by wearing part finally by the means increasing material manufacture, after reparation, finally give intact part.
Summary of the invention
In order to overcome the deficiency of background technology, the invention provides a kind of adopt 3-D scanning mode obtain wearing part data and by increase material manufacture repair metal parts method.
The present invention three-dimensional data by 3-D scanning wearing part, then Boolean calculation is carried out with the three-dimensional data of intact part, subtract each other the three-dimensional data obtaining having worn out part, pile up out by wearing part again through the means increasing material manufacture, finally give intact part, it is achieved that accurately measuring of metal parts abrasion numerical value is repaired with quick.
The present invention makes full use of existing resource, uses and quickly increases material manufacturing technology, it is achieved the efficiently and accurately property that component of machine is repaired.
Accompanying drawing explanation
Fig. 1 is the part of abrasion.
Fig. 2 is complete part.
Fig. 3 is the data that the data Boolean calculation after partial data and abrasion subtracts each other the worn-out part obtained.
Detailed description of the invention
With three-dimensional scanning device, wearing part is scanned, the three-dimensional data of part after being worn and torn.By Boolean calculation, deduct wearing part data with complete part data, it is thus achieved that the accurate data at worn-out position.Recycling quickly increases material manufacturing technology, repairs according to the three-dimensional data that Boolean calculation obtains, and can rapidly and efficiently complete the reparation to abrasion parts.
Claims (3)
1. one kind increases the method that metal parts is repaired in material manufacture, it is characterized in that, utilize 3-D scanning technology, the part of abrasion is carried out 3-D scanning, obtain the three-dimensional data of wearing part, it is contrasted with the initial three-dimensional data of part, uses Boolean calculation, after subtracting each other, obtain the data at worn-out position.Pile up out by wearing part again through the means increasing material manufacture, finally give intact part.
2. metal parts method is repaired in increasing material manufacture according to claim 1, it is characterised in that using 3-D scanning mode to obtain abrading section data, recycling increases material manufacturing technology and repairs.
3. metal parts method is repaired in increasing material manufacture according to claim 1, it is characterised in that 3-D scanning, Boolean calculation, and increasing material manufacture reparation is that the control by computer program realizes.
