The specific embodiment
Below the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
As Fig. 2, shown in Fig. 3 and Fig. 4, the present embodiment provides a kind of supersonic electric arc spray gun, comprise blowpipe 1, anodal wire-feeding pipe 2, negative pole wire-feeding pipe 3 and insulation board 4, blowpipe 1 end is connected with poly-powder accelerating tube 5, anodal wire-feeding pipe 2 and negative pole wire-feeding pipe 3 ends are connected with ignition tip 6, blowpipe 1, anodal wire-feeding pipe 2 and negative pole wire-feeding pipe 3 are through insulation board 4, all adopt locking nut 7 to be fixed on insulation board 4, blowpipe 1 is fixed on insulation board 4 centers, anodal wire-feeding pipe 2 and negative pole wire-feeding pipe 3 are arranged on air delivery pipe 1 one sides, its end intersects for Arc district 8, become 60 ° of angles directly to enter blowpipe 1.
After after the both positive and negative polarity wire-feeding pipe connects, prolong pipeline can boundling after diameter be no more than 30mm, nearly 10 times of volume-diminished.Both positive and negative polarity wire-feeding pipe end intersects 60 ° of angles and directly enters hyperbaric chamber accelerating tube design, boundling starting the arc district powder at utmost, and the very first time is ejected into substrate surface, improves the material surface deposition, reduces loose arc dust.The both positive and negative polarity wire-feeding pipe directly enters the accelerating tube design, uses separately this part to change nozzle and can spray 100mm endoporus tube wall, and the degree of depth is adjustable (build-out).
Wherein, blowpipe 1 is provided with hyperbaric chamber 9 through the part of insulation board 4, hyperbaric chamber 9 is communicated with described poly-powder accelerating tube 5, and the Arc district 8 of anodal wire-feeding pipe 2 and negative pole wire-feeding pipe 3 is arranged in the blowpipe 1 that hyperbaric chamber 9 ends are connected.Hyperbaric chamber and poly-powder accelerating tube are processed by the antiseized glutinous crystal of insulation high-temperature-resistant, and the effect of hyperbaric chamber is compressed air to be assembled speed over velocity of sound when accelerating tube ejects, and can greatly improve bond strength and improve coating quality.
Wherein, arc pistol is set with dust collection cover 10 outward, and collecting hood 10 1 ends and insulation board 4 are threaded connection, and dust collection cover 10 outer setting have scale 11.
But the spray distance of rotation screw thread adjustment criteria, make new operator also ability go out standard quality, reduced work difficulty.
Wherein, be provided with dust recovery tube 12 on insulation board, be communicated with dust collection cover 10.
Wherein, dust collection cover 10 other ends are set with soft rubber cover 13.During work, soft rubber cover 13 is close to workpiece base material 14.The soft rubber cover plays the elastic packing effect, can further prevent that metallic dust from leaking, the operator's who has effectively improved working environment.
The effective recycling of metallic dust that the hyperacoustic zone arc pistol of the present embodiment produces, no longer include loose arc and be diffused into contaminated environment in air.
The operation principle of thermal spraying apparatus: be to produce high temperature under arcing, when the wire that copper zinc-aluminium etc. will be sprayed is atomized into molten of small that dissolve or half melting state, with the supersonic speed gases at high pressure, sprays and strike on the surface of the work through blasting treatment fast.Form metallurgical binding with the body base material, form cover layer, and put and mutually diffuse to form new crystallizing layer diffusion depth more than 20 microns by microbonding, its result can further improve the bond strength of coating and matrix.
The technological process of this equipment is: anodal wire-feeding pipe and negative pole wire-feeding pipe that sprayed on material is sent into the mutually insulated belt current by wire-feed motor arrive ignition tip and intersect in accelerating tube, positive and negative crossing generation electric arc atomization wire, be sprayed onto substrate surface by the pressure-air brute force and form coating, do not form the loose arc powder of coating just by the dust recovery tube, by vavuum pump, sucked back in the filtered and recycled tank and can also recycle.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
