Have and in metal spray gun, place the such portable electrostatic spray torch of high pressure generator, can in various devices, be used in a large number.High pressure generator is accommodated in the spraying plating gun barrel usually or is contained in the handle.Also knowing simultaneously, is that high pressure generator is placed between lower, the free end of wire pistol and handle as a part independently.Yet the common shortcoming of all these devices is: no matter the trial of running counter to desire usually how, only aspect size, weight and weight center, as the instrument in long-time hand held, these devices all are quite unfavorable.
Therefore, purpose of the present invention is exactly to make a kind of portable electrostatic spray torch of form noted earlier, and it is very little, and is in light weight, and can more easily arrest than the device of form known.
The concrete solution that realizes purpose of the present invention and propose will be described in detail in conjunction with following embodiment shown in the drawings.
Fig. 1 be pass the coating spray torch profile and
Fig. 2 passes the spraying plating gun barrel along the II among Fig. 1-II line, i.e. the drawing in side sectional elevation of the direction of arrow as shown.
Shown blackwash sprayer comprises rifle body 10 preferably made of aluminum, and this rifle body is cylindrical basically.The plating gun barrel 11 that preferably is made of plastics, this spraying plating gun barrel spiral is screwed into the front end of rifle body 10, and the core of this spraying plating gun barrel has the drawing in side sectional elevation of three cloverleaf forms as shown in Figure 2.Thus, in rifle body 10 dorsal areas, below it, will have the high pressure generator of plastic mulching layer with spiral and be made of metal and and the compressed air guide wire 13 of high pressure generator runs parallel be connected and fixed.At last, plate machine 14 is hinged on the rifle body 10.
Like this, the coating spray torch is made up of following five fundamental components, and promptly the rifle body 10, spraying plating gun barrel 11, and high pressure generator 12, compressed air guide wire 13 and trigger 14, these main components will be described in detail below.
Control channel 15 runs through rifle body 10 in the vertical.In this passage, control assembly 16 is placed movably and is positioned at that this coating valve axially runs through control channel 15 on the bar of coating valve.Control assembly 16 comprises controls dome 16a and control dome 16b rigidly, and they can move with interior work by control assembly 16 partly.All define the position of control assembly on valve bar 17 on both sides in the helical spring 18 and 19 that control assembly 16 works.The air interface channel that control channel is extended by a deflection runs through, promptly in the section of control assembly 16.Air duct is with two form continuities that extend to the air duct 21 of rifle body 10 leading portions, of can only see these two passages 21 in the accompanying drawings.These two passages 21 can be opened separately and can be closed by means of bolt 22 respectively by corresponding air interface channel 20.Rifle body 10 also further comprises coating bindiny mechanism 23, it has coating derives passage 24, passage 24 is last near the positive place's introducing of rifle body 10 front ends control channel 15, and rifle body 10 also comprises a thorax that is positioned at the front equally, the high pressure pilot cable 25 in this thorax.Lance tube 11 is run through by coating passage 26 centers, in coating passage 26, has valve bar 27 to pass.When being fixed to spraying plating gun barrel 11 on the rifle body 10, coating passage 26 and control channel 15 interrelate, and valve bar 27 closely is connected on the valve bar 17, and coating valve 28 is installed in the front end of valve bar 27.Valve passage 26 extends to spraying plating device nozzle 29 over there to coating valve 28.That also extends in spraying plating gun barrel 11 also has two air ducts 30 and 31.When pipe 11 has been installed on the rifle body 10, two passages 21 of air duct 30 and 31 continuity rifle bodies 10, thus an air duct 30 provides the control air at another air duct 31 with two air cantilevers 33.At last, high-tension cable 34 extends in spraying plating gun barrel 11, and this cable 34 electrically is connected on the high-tension cable 25 of rifle body 10, and provides electric energy by high value resistor 35 for jetelectrode 36.When spraying plating gun barrel 11 was put on the rifle body 10, alignment pin 37 was used as the position of rotation that limits spraying plating gun barrel 11.
One end of high pressure generator 12 screws in rifle body 10, and thus, the output of its electricity is received on the high-tension cable 25 that extends in rifle body 10.At its other end, high pressure generator 12 is received on the low pressure supply cable 38.High pressure generator 12 mainly is made up of transformer, high-pressure series level and insulating barrier, and as narrating: this overcoat has the shape of handle.
Compressed air guide wire 13 has an end to screw in rifle body 10, and is useful on the connector of compressed air supply line at its other end 13a.Pipe 13 extends in the back of high pressure generator 12, and releasably is connected to preferably for stable that this structure has guaranteed that high pressure generator 12 and compressed air guide wire 13 can be booked by operator's hand above it.
As what narrated, trigger 14 is hinged on the rifle body 10, and comprises the switch element 39 that can be hinged out.This switch element 39 be arranged on high pressure generator 12 with interior proximity switch (not shown), snap switch for example, action matches.
The static spray torch of being narrated is worked as follows.When trigger 14 is driven by the user, movably control dome 16b and at first move (towards the accompanying drawing left direction), consequently, flow to compressed air in the compressed air guide wire through behind the thorax 15, enter into two compressed air channels 21 by thorax 20 again and continue from entering air nozzle 32 and air cantilever 33 by way of 30 and 31 here.Control dome 16b one knocks control dome 16a, The whole control parts 16 just all are moved (left direction in the figure), its result is exactly that coating valve 28 is opened by interconnected valve bar 17 and 27, and coating comes up from the injector nozzle 29 as nozzle.At the same time, switch contact 39 is proximity switch (not shown) of so close high pressure generator 12, thereby make this proximity switch be switched on, for spraying plating electrode 36 provides from high pressure generator 12, through high-tension cable 25 and 34 and the plating current of high-tension resistive 35.When trigger 14 was released, running was carried out in antipodal mode, that is to say that the supply of coating at first is under an embargo, and then, the supply of air also is under an embargo.The ratio of nozzle air and control air discriminably by swivel bolt 22(and) stroke of trigger or change the trigger impedances by swivel bolt 40 and adjust arbitrarily.When switch element was hinged opening, the spraying plating process can be carried out with pure mechanical system, that is to say, does not need the territory of electricity.
Rifle body 10 also can be made with plastics.But the use metal, particularly the aluminium that operating weight is light in this case is best, connects because this rifle body includes the spiral of some.Yet, what must lack is: coating is supplied with part 24,23 must be near bindiny mechanism's device of spraying plating gun barrel 11, particularly for those given rifles of under high coating pressure, working, because only there is a few components of rifle body 10 to be subjected to coating pressure, and for weight reduction, most of parts of rifle body 10 all are manufactured into thin-walled shape.The implication of weight reduction comprises that also spraying plating gun barrel 11 has on its length direction all effective parts all to have as shown in Figure 2 cross section, promptly those of tube wall comparatively speaking not necessarily part all be removed.At last, with regard to weight reduction and aspect reduced in size, the most important thing is that the insulating barriers of high pressure generator 12 itself have been represented handle, that is to say, up to the present traditional structure is opposite, and high pressure generator (insulating barrier that it is arranged) is so as to being introduced into a hollow handle.Equally, compressed air guide wire 13 and trigger 14 also can be selected to use the plastics manufacturing, but light metal remains the best.
The static coating spray torch of being narrated can be discerned by its structure.This mechanism guarantees the simple manufacturing and simple installation of its part.Yet what it was outstanding is also advantageous in that rifle is very little, very smooth, and than can be by comparison device available on the market lighter on weight.Additional advantage is exactly a very useful center of gravity.This point has just caused such fact comprehensively, even that is: the user uses this coating spray torch with integrated high voltage generator also can not feel tired for a long time.
Typical embodiments indicated and narration is a kind of compressed air spraying and attached coating spray torch that helps the control air of utilizing, but, this rifle also can be designed to obstructed compressed-air actuated high pressure rifle, and vigor high-pressure air tube 13 fully thus, simultaneously, spray torch nozzle 29 is also replaced by corresponding high pressure nozzle.If in this case, produce a very large weight saving, the spraying plating gun barrel just can be become following pattern by specialized designs so: air duct 30 and 31 is omitted, and cross section is designed to two clovers formation cylinder barrel shaped respectively.Coating spray torch of the present invention is particularly suitable for using high coating pressure and attached helping under the compressed-air actuated situation to work, and do not need to revise in essence on typical embodiments, revising only is to tend to more in the design of the air exhaust openings of metallising gun barrel front end.
