Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings.
See Fig. 1, a kind of utilize gap, groove constraint part thickness, the metal cladding forming device of slice width,
Including be arranged on can substrate 5 on the 3D displacement platform that tri-sides of X, Y, Z move up, and
Being arranged on the fixing feed appliance 1 above substrate 5, fixing have gap between feed appliance 1 and substrate 5, fixes and send
The feeding port 2 vertical with substrate 5 is offered, bottom fixing feed appliance 1 centered by feeding port 2 in the middle part of glassware 1
If being provided with the groove 3 that dried layer is arranged at equal intervals, it is some little recessed that every layer of groove includes being distributed on same circle
Groove, is filled with correspondence if being positioned in one or more layers groove of internal layer in the groove 3 arranged at equal intervals of dried layer
The screw that groove is filled and led up.
A kind of using method of the metal cladding forming device utilizing gap, groove constraint part thickness, slice width,
Comprise the following steps:
Step one: regulate fixing distance between feed appliance 1 and substrate 5 according to the thickness of part, according to part
Slice width select use groove 3, other untapped groove 3 screws fill；
Step 2: motlten metal 4 is coated in solid by the feeding port 2 of fixing feed appliance 1 by pressure P
Determine, at the gap of feed appliance 1 and substrate 5, to form uniform cladding layer；
Step 3: motlten metal 4 persistently coats on the substrate 5, substrate 5 is on tri-directions of X, Y, Z
Mobile, shape required part.
Motlten metal 4, due to surface tension and adhesion, does not passes through will not crossing when sprawling of pressure injection
The groove that screw is filled and led up.
The present invention mainly improves the precision of formation of parts from the standpoint of metal melting and coating process and improves shaping
Efficiency.Specifically, the present invention utilizes gap, groove constraint part thickness, the metal cladding forming of slice width
Method, is the surface tension utilizing metal material, utilizes fixing feed appliance to define the feeding port of centre, Gu
Determine bottom feed appliance, there is symmetrical groove, by the width of adjusting grooves, metal zero when retraining deposition
Slice width D of part, fixing gap between feed appliance and substrate is used for retraining the thickness of part, substrate can X,
Tri-sides of Y, Z move up.Under the effect of pressure P, motlten metal 4 is by by fixing feed appliance 1
Feeding port 2 coat on the substrate 5, form one layer of uniform cladding layer, its cladding layer width D is by fixing
Above feed appliance, the distance between groove 3 determines, due to metallic surface tension force and adhesiveness, when it is sprawled
Groove 3 will not be crossed.Different groove 3 combinations form different distance size, and no groove 3 is screwed on screw,
Make it concordant with fixing feed appliance 1 baseplane, now metal cladding is sprawled and do not produce impact；Cladding thickness
Spend and determined by the gap between fixing feed appliance 1 and substrate 5.By substrate 5 in tri-directions of X, Y, Z
Upper movement, shapes required part.Forming accuracy of the present invention is high, reproducible, and groove structure is simple, can
Accelerate metal cladding forming speed, good quality of product, be conducive to improving element precision and forming efficiency, no
Need substantial amounts of frock, it is only necessary to control forming technology and just can reach.By tying mutually with numerical control system
Closing, groove has unlimited compounding power, and stops that shaping layer pitch modification is convenient.
In metal coating procedure, when having symmetrical groove 3 to retrain deposition bottom fixing feed appliance 1
Slice width D of metal parts, distance D1 of the first groove 3-1 and the second groove 3-2 formation, the 3rd groove 3-3
Distance D3 formed with distance D2, the 5th groove 3-5 and the 6th groove 3-6 of the 4th groove 3-4 formation,
Owing to metal has certain surface tension, it is difficult to carry out wider sprawling by groove, such as: coating
Width is D1 cladding layer, metal parts when retraining deposition by the first groove 3-1 and the second groove 3-2
Slice width D；If the cladding layer wanting coating width to be D2, it is necessary to the first groove 3-1 and the second groove 3-2
Fill with screw so that it is concordant with bottom fixing feed appliance, come by the 3rd groove 3-3 and the 4th groove 3-4
Slice width D of metal parts during constraint deposition；If the cladding layer wanting coating width to be D3, it is necessary to groove
First groove 3-1, the second groove 3-2, the 3rd groove 3-3 and the 4th groove 3-4 screw are filled so that it is with
Fix bottom feed appliance concordant, metal parts when retraining deposition by the 5th groove 3-5 and the 6th groove 3-6
Slice width D, by that analogy, different groove distance can be set according to the dimensional accuracy of formation of parts,
Fixing gap between feed appliance 1 and substrate 5 is used for retraining the thickness of part, utilize substrate 5 can X,
Tri-sides of Y, Z move up, and are in layer filled with from part, until required part forming is complete.
Embodiment: shaping a part, it is desirable to thickness is 1mm, slice width is 0.5mm, comprises the following steps:
Step one: by between fixing feed appliance 1 and substrate 5 distance regulate to 1mm, make the first groove 3-1 and
Distance D1=0.5mm that second groove 3-2 is formed, other untapped groove 3 screws are filled；
Step 2: motlten metal 4 is coated in solid by the feeding port 2 of fixing feed appliance 1 by pressure P
Determine, at the gap of feed appliance 1 and substrate 5, to form uniform cladding layer；
Step 3: motlten metal 4 persistently coats on the substrate 5, substrate 5 is on tri-directions of X, Y, Z
Mobile, shape required part.
