Specific embodiment
Below, the present invention is specifically described by exemplary implementation method.It should be appreciated, however, that not entering one
In the case of step narration, element, structure and features in an implementation method can also be advantageously incorporated into other embodiment
In.
In the description of the invention, it is necessary to explanation, term " on ", the orientation of the instruction such as D score or position relationship be base
In the position relationship shown in accompanying drawing 3, it is for only for ease of and describes of the invention and simplify description, signified rather than instruction or hint
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to of the invention
Limitation.Additionally, term " first ", " second ", " the 3rd " are only used for describing purpose, and it is not intended that indicating or implying relatively heavy
The property wanted.
Referring to Fig. 1, Fig. 1 is the operation principle schematic diagram of metal surface remelting method of the present invention.As shown in figure 1, a kind of gold
Metal surface remelting method, comprises the following steps：
In the path planning stage, walking path of the thermal source along the face to be processed of metal parts 3 is determined by CAD/CAM softwares, entered
And choose multiple points to be processed, and then the local face to be processed of the metal parts 3 according to where point to be processed along the walking path of thermal source
Curvature and position determine the normal of point to be processed, and then it is little with to be processed normal angle θ value to set source center axis
In 45 °；
Preparatory stage, will be fixed on workbench 1 by the metal parts 3 of increasing material manufacturing, meanwhile, by thermal source output 23
It is installed on on the corresponding machining cell of workbench 1, metal parts 3 as shown in Figure 1 is obtained by Direct Metal Deposition technology, has
Body is, using thermal source fusing metal powder or metal wire material, meanwhile, according to certain path to molten metal layer upon layer with
Directly manufacture metal parts 3；
Process segment, machining cell drives thermal source output 23 to move according to the routing information in path planning stage, meanwhile,
The relative position of thermal source output 23 and the point to be processed of metal parts 3 is adjusted immediately according to the normal of point to be processed, so that θ values are not
More than 45 °, it is necessary to explanation, the determination to the local face normal to be processed of metal parts 3 is that those skilled in the art pass through to be used to
It is attainable with technological means, for example, the 3-D graphic of metal parts 3 is converted into STL forms, meanwhile, by metal parts 3
Each part face to be processed is defined as triangle surface, so can each triangle surface of initiative recognition normal, additionally, the present invention will
The effect that θ values are set to no more than 45 ° is, in order that must be through the partial face of adjacent metal part 3 after thermal source re melting process
Curvature is same or like, and then obtains the surface of metal parts 3 of any surface finish,
At the same time, thermal source output 23 is started, thermal source output 23 sends thermal source to the point to be processed of metal parts 3, and
Melted using the metal near thermal source point to be processed to metal parts 3, it is necessary to be illustrated, thermal source can be with increasing material manufacturing
Thermal source be same thermal source, i.e., needed thermal source output using same thermal source output 23, but during for metal surface remelting
23 parameter adjustment is the parameter for meeting remelting processing requirement, additionally, thermal source can also be used only for the only of metal surface remelting
Vertical thermal source,
At the same time, moving heat source output 23, realizes the re melting process in the face to be processed of whole metal parts 3.
On the one hand metal surface remelting method of the present invention by way of using to the face remelting to be processed of metal parts 3, takes
For traditional Milling Process mode, so that without complicated process equipment and the course of work, and then reduce to metal parts 3
The processing cost in face to be processed and process time；On the other hand, the center of thermal source is sent from thermal source output 23 by adjusting
Line is not more than 45 ° with to be processed normal angle θ value, so as to ensure that (i.e. thermal source is delivered to specified to be added thermal source accessibility
Accessible situation about blocking during work point) while, it is ensured that the quality on the whole surface of metal parts 3.
Additionally, the present invention carries out remelting on the surface of metal parts 3, the thin of the surface of coated metal part 3 can be prepared with this
Crystal grain strengthening layer, and then improve the mechanical performance of metal parts 3.
Preferably, in the path planning stage, setting source center axis are 0 ° with this normal angle θ values, i.e., from thermal source
The center line that thermal source is sent in output 23 overlaps with the normal of the metal parts 3 point to be processed, with this so that through re melting process
The partial face of metal parts 3 afterwards is best in quality；In the process segment, machining cell adjusts thermal source output 23 and the metal zero immediately
The relative position of the point to be processed of part 3, so that θ values level off to 0 °.
In addition, in the path planning stage, path width is consistent when the width of machining path is with actual fusing, and makes to own
The set in path can be completely covered face to be processed.
Preferably, thermal source is that laser, electron beam, beam-plasma or electric arc are one kind of.
Further, metal surface remelting method of the present invention is further comprising the steps of：In the process segment, to thermal source output
23 carry out parameter adjustment, with formed can either ups and downs metal on the local face to be processed of fusing metal part 3, can make again
The shallow pool of molten metal quick solidification.The present invention is by the parameter adjustment to thermal source output 23 it is possible to prevente effectively from fusing
Metal occur under gravity it is obvious under drop down, and then improve the quality on the surface of metal parts 3.

The normal of point overlaps with gravity direction.
Metal surface remelting method of the present invention is overlapped by adjusting the normal of the point to be processed of metal parts 3 with gravity direction,
There is the phenomenon dropped down under liquid metal during face remelting to be processed to metal parts 3 so as to avoid, and then be effectively guaranteed gold
Belong to the surface quality of part 3.
It should be noted that the normal of the adjustment point to be processed of metal parts 3 overlaps with gravity direction, it is people in the art
Member is attainable by conventional techniques, for example, the point to be processed of metal parts 3 can be obtained according to the CAD model of part
Horizontally and vertically the normal (the determination method of normal is referring to foregoing) of profiled outline, then determines the to be processed water of metal parts 3
The tangent line of gentle vertical profiled outline, the plane for then adjusting the attitude of workbench 1 to cause two tangent lines to synthesize and horizontal plane
Overlap, now, the normal of the metal parts 3 point to be processed overlaps with gravity direction.
In addition, carrying out surface to baroque metal parts 3 (such as impeller) using metal surface remelting method of the present invention
During re melting process, the situation of the thermal source conveying of thermal source output 23 being hindered due to there are some structures, therefore, can be difficult to avoid that
The phenomenon that the normal of the point to be processed of metal parts 3 does not coincide with gravity direction, now, on the one hand needs adjustment work platform 1
Attitude is with so that the normal of the point to be processed of metal parts 3 is close proximity to gravity direction；On the other hand, it is necessary to thermal source output 23
Parameter adjustment is carried out, so as in the case where the normal of the point to be processed of metal parts 3 and gravity direction are inconsistent, it is to avoid liquid gold
Category drops down under occurring significantly.
