Abstract
The utility model provides a high efficiency arc pistol having secondary atomizing function. Along the vertical direction of the axial cord thereof, the proper position of the central air hole of a back pistol body is provided with secondary atomizing compressed air holes from 4 to 6 with the hole diameter from 2 to 4 mm passing through the central air hole. The outside of a shroud type spray pistol sleeve is provided with a proper outer pistol sleeve and is connected with the back pistol body via screw threads. The high efficiency arc pistol improves the spray coating efficiency of the spray coating pistol for preparing dense sound metal coating. Taking sherardizing as example, the spraying efficiency is improved from 30 kg/h to 70 kg/h.
Description
The utility model belongs to thermal spraying gun
Electric arc spraying is that two one metal wires of desire spraying are done to utilize its end contacting ignition arc to come the deposite metal from the consumption electrode, utilizes compressed air stream that the motlten metal atomizing is formed atomized particle stream again, is ejected into a kind of technology that substrate surface forms metal coating.This technology mainly is to implement to finish by arc pistol.
The existing single sealing atomizing structure of the general employing of formula arc pistol of shrouding, as the fixed electric arc metallizing gun of SCD-3 type, the atomization process of its motlten metal blows out one strong compressed air by means of the rear lance centre bore and flows and finish a kind of shroud in the formula spray gun cover.
Arc pistol is because of its high efficiency, low energy consumption, easy to control and be widely used in automatic spraying production line.But the spray efficiency of existing spray gun is difficult to reach the requirement of modern production line, and existing arc pistol generally adopts the wire of φ 2mm, 8 meters/minute of the highest wires feed rate.With spray zinc is example, and the highest spray efficiency is 30Kg/h.Improve the spray efficiency of existing spray gun, or increase the wire cross section, or improve wire feed rate.But these measures have very big limitation, because the single sealing atomizing structure of existing arc pistol can not adapt to owing to increasing the atomizing requirement that wire cross section or wire feed rate cause, must cause bum coating, even spraying process can't be carried out.
The purpose of this invention is to provide a kind of high efficiency arc pistol that improves existing arc pistol spray efficiency and coating quality, propose the newly-designed high efficiency arc pistol that the utility model has the secondary-atomizing function.
A kind of efficient arc pistol of the utility model, by insulation rifle body, hollow conducting rod and shroud formula spray gun cover and form, insulation rifle body has a centre porosity that runs through along axial line, its end connects with the compressed air entrance hole, it is two conducting rod holes of 30 °～45 ° that centre porosity both sides axial symmetry is distributed with angle, two hollow conducting rods embed respectively in this hole, shrouding formula spray gun cover inner is conical cavity, its convergence end forms φ 6-10mm perforate, be the spray gun spout, and it is concentric with rifle body centre bore, shroud formula spray gun cover and insulation rifle body thread connection, this efficient arc pistol is characterised in that: in the appropriate location of insulation rifle body centre porosity, along its axis normal direction 4～6 apertures that connect with centre porosity being arranged is the secondary-atomizing compressed air apertures of 2～4mm, shrouding the outer holster of the suitable shape of formula spray gun cover outer setting one, also connecing fixingly, forming appropriate gap between spray gun cover outer wall and the outer holster inwall by screw thread and the rifle sports association of insulating.
Advantage of the present utility model:
1. improved the spray efficiency of arc pistol, and can obtain fine and close high-quality coating, can use φ 3mm wire, maximum wire feed rate is 11 meters/minute, is example with spray zinc, and maximum spray efficiency reaches 70Kg/h.
2. strengthened cooling effect, the service life of having improved burner elements to the spray gun cover.
Accompanying drawing 1 is the efficient arc pistol structural representation of the utility model.
Accompanying drawing 2 is a secondary-atomizing pore profile.
(1) insulation rifle body centre porosity, (2) secondary-atomizing compressed air apertures, (3) shroud formula spray gun cover, (4) outer holster, (5) insulation rifle body, (6) compressed air ingress pipe, (7) hollow conducting rod, (8) spray gun spout.
Now further specify by reference to the accompanying drawings the utility model feature: at insulation rifle body centre porosity (1) The appropriate location, along its axis vertical direction 4～6 secondary-atomizing compressed air apertures (2) are arranged, connect with centre porosity (1), diameter is 2～4mm, holster (4) outside the one suitable shape is set outside shrouding formula spray gun cover (3), be connected and fixed by screw thread and rifle body (5), entered the compressed air of insulation rifle body centre porosity (1) by the compressed air ingress pipe, punish into two-way in secondary-atomizing compressed air apertures (2), one the tunnel continues to blow out along centre porosity, at the primary atomization of spray gun spout inner edge realization to motlten metal, another road, blow out through secondary-atomizing compressed air apertures (2), carry along outer holster (4) inwall and the air channel, the formed gap of outer wall of shrouding formula spray gun cover (3), in spray gun spout outer rim the atomized particle stream of passing through primary atomization is realized secondary-atomizing, and atomized particle stream is had concurrently compression, thereby obtain the more atomized particle stream of Shu Mi. Realized the electric arc spraying of high-efficiency high-quality.
Application example:
The utility model is used for cast tube spray zinc automatic assembly line.6 secondary-atomizing compressed air apertures, the aperture of airport are φ 3mm; The zinc filament diameter that uses is φ 3mm, and wire feed rate is 10 meters/minute, and spray zinc efficient is 60Kg/h.
