The specific embodiment
Fig. 1 adopts the principle schematic of shock peening in metal 3D forming process; Adopt the printer of this principle can use the metal 3D printer integrated spray nozzle structure for interlayer shock peening of the present utility model, nozzle arrangements of the present utility model comprises melting-painting nozzle, melting-painting nozzle is for pulverized powder, also comprise strengthening nozzle, strengthening nozzle is used for spraying shot-peening or Emission Lasers.
The structure that cooperatively interacts between strengthening nozzle in the utility model and melting-painting nozzle can have five kinds: the first is that melting-painting nozzle is arranged on center, strengthening nozzle is arranged on melting-painting nozzle periphery, strengthening nozzle comprises 3-5 jet pipe, and each jet pipe can be controlled and be realized independent shot-peening by electrical system.The second is that strengthening nozzle is arranged on center, and melting-painting nozzle is arranged on strengthening nozzle periphery, and melting-painting nozzle comprises 3-5 jet pipe, and each jet pipe can be controlled and be realized independent pulverized powder by electrical system; The third is that melting-painting nozzle comprises a plurality of jet pipes, and strengthening nozzle comprises a plurality of jet pipes, and the jet pipe of the jet pipe of melting-painting nozzle and strengthening nozzle is interphase distribution and circumference uniform distribution successively; The 4th kind is that strengthening nozzle is arranged on melting-painting nozzle periphery, and strengthening nozzle comprises 3-5 laser head, and each laser head is Emission Lasers separately; The 5th kind of strengthening nozzle comprises 1 laser head, and laser head is arranged on center; Melting-painting nozzle arranges the periphery of strengthening nozzle.
Figure 2 shows that at 3D and print the schematic diagram that in Ti alloy part process, Ti alloy cladding layer is adopted shot-peening shock peening.Shot peening strengthening nozzle becomes one with coaxial melting-painting nozzle and the laser focusing head heating for metal dust, and melting-painting nozzle and strengthening nozzle respectively comprise a plurality of jet pipes, the jet pipe of the jet pipe of melting-painting nozzle and strengthening nozzle is interphase distribution and circumference uniform distribution successively, can to accumulation horizon, carry out shock peening rapidly afterwards and not need other auxiliary equipment in the accumulation that completes certain number of plies, its basic step be as follows:
1] cladding layer is shaped:
First adopt metal 3D printing technique to form some cladding layers at substrate surface, the bed thickness 0.05-0.3mm of every one deck cladding layer, when cladding layer reaches certain thickness, stops 3D printing-forming;
2] cladding layer heating:
By heater, cladding layer upper surface is heated to 100 ℃-700 ℃;
3] cladding layer subregion:
Cladding layer is divided into frontier district and mesozone 7; Wherein frontier district is comprised of external boundary region 6, or is comprised of external boundary region 6 and inner edge battery limit (BL) 8; External boundary region 6 is that part outline is offset the closed area of the formed closed curve of 0.5-3mm and the formation of this outline to inside parts, and inner edge battery limit (BL) 8 is that in part, profile is offset the closed area of the formed closed curve of 0.5-3mm and this interior profile formation to inside parts; Mesozone 7 is other regions except frontier district;
4] cladding layer strengthening:
Strengthening is sequentially mesozone 7 again, first frontier district, and the 0.5-0.8 that the coverage rate in mesozone when strengthening is frontier district doubly;
5] cladding layer continues to be shaped:
Some cladding layers, bed thickness 0.05-0.3mm are continued to form in cladding layer top after strengthening;
6] repeating step 2,3,4,5 until metal 3D printout be shaped.
In the utility model, because the deposit thickness that can penetrate at the lower shock peening of different condition (different schedule of reinforcements, differing formed material) has larger difference, so the number of plies that has been shaped before strengthening need to be set according to the difference of actual conditions.As adopt mechanic shot peening when strengthening to need successively or every which floor carry out one-shot strengthening, adopt when laser impact intensified and can even after tens layers, carry out one-shot strengthening being shaped ten layers.
In the utility model, according to the different attribute of material (as moulding), can heating-up temperature be set to different predetermined values, can bring into play better like this ability of shock peening aspect enhancing part density.
In the utility model, can take different strengthening parameter (comprising pressure, number of times, speed, shot-peening quality size, translational speed, moving interval etc.) at the diverse location of cladding layer, or according to certain order, adjust the strengthening order of cladding layer diverse location, and then reach character and the size that the technique of strengthening by adjustment regulates the residual stress at inside parts diverse location place, thereby reach the effect that guarantees drip molding precision when increasing density.
