Description
Technical field
The present invention relates to a kind of air plasma cutting gun, the JW series air plasma cutting gun of particularly a kind of energy-conservation province consumption structure.
Background technology
In production operation at present; The air plasma cutting is the advanced product that substitutes traditional oxygen-acetylene cutting; It not only can more effectively cut carbon steel; Can also the material that oxygen-acetylene such as stainless steel, non-ferrous metal can not cut be cut, advantage be pollute less, efficient is high, slot is smooth.Cutting power and cutting effect are by the decision of four aspects such as life-span of magnetic pinch, mechanical compress effect, hot compression effect, rifle head and electrodes conduct mouth.Existing air plasma cutting is relatively poor at the efficiency control ratio of the aspects such as life-span of mechanical compress effect, hot compression effect, rifle head and electrodes conduct mouth, is prone to cause the damage of the wasting of resources and air plasma cutter.
Summary of the invention
To the shortcoming of existing air plasma cutting, the JW series air plasma cutting gun that the present invention provides a kind of novel energy-conservation province to consume structure.
To achieve these goals, the measure that the present invention taked
The JW series air plasma cutting gun of a kind of energy-conservation province consumption structure comprises gun barrel, rifle head, and first end of rifle and protective cover connect and compose the rifle body case; The rifle head other end is connected with the cutting gun handle; Be provided with gun barrel in the rifle head, gun barrel is connected with the rifle body of setting in the rifle head; Be disposed with spring, steel ball in the rifle body; Steel ball contacts with spring; Simultaneously, steel ball and electrode one end in contact, the electrode other end contacts with current divider, and the current divider other end is connected with ignition tip; Ignition tip is arranged at the protective cover exit position;
Be respectively arranged with electrode helicla flute, ignition tip spiral inner wall groove in described electrode, the ignition tip;
Described protective cover is protected ignition tip to more than 60%;
Described cutting gun handle is provided with touch-switch, and cutting gun handle monnolithic case is circular arc and is provided with three roads and points recessed fox shape and structure.
Beneficial effect of the present invention: simple in structure, cost is low; Efficient is high, saves energy consumption, improves the service life of air plasma cutter; Holding of cutting gun handle feels comfortable, reduces fatigue strength.

The specific embodiment
The JW series air plasma cutting gun of a kind of energy-conservation province consumption structure, as shown in Figure 1, comprise gun barrel 1, rifle head 2, rifle head 2 one ends and protective cover 3 connect and compose the rifle body case; Rifle head 2 other ends are connected with the cutting gun handle; Be provided with gun barrel 1 in the rifle head 2, gun barrel 1 is connected with the rifle body of setting in the rifle head 2; Be disposed with spring 5, steel ball 6 in the rifle body; Steel ball 6 contacts with spring 5; Simultaneously, steel ball 6 and electrode 4 one end in contact, electrode 4 other ends contact with current divider 7, and current divider 7 other ends are connected with ignition tip 8; Ignition tip 8 is arranged at protective cover 3 exit positions; As shown in Figure 2, be respectively arranged with electrode helicla flute 9, ignition tip spiral inner wall groove 10 in described electrode 4, the ignition tip 8.In the patent working process, at first will utilize steel ball 6 to go over the inwall that four apertures are diverted to the rifle body equably from the air draught that gun barrel 1 gets into, make it behind inwall, to come out from rifle body head in radial loop, whole rifle body is evenly cooled off; Traditional refrigerating gas is to get into directly to come out to rifle body head from gun barrel 1, and the inwall of rifle body is just flow through vertically, and cooling effect is bad.Secondly; The electrode helicla flute 9 of electrode 4 heads and the ignition tip spiral inner wall groove 10 of ignition tip 8 inwalls; Make air draught 11 form more anxious eddy flow along helix herein; In the compression of radially having strengthened electric arc, improved the degree of ionization of air and the energy density of electric arc, make the mechanical compress effect of electric arc more effective; Traditional air draught is in that radially the compression to electric arc is general, if directly add the pressure of atmospheric, and in the influence that axially will produce stabilising arc to electric arc, current interruption easily.Like Fig. 3, Fig. 4, shown in Figure 5; And then be that protective cover 3 is protected ignition tip 8 to more than 60% with the protective cover lengthening, air draught has certain pressure when between protective cover 3 and ignition tip 8, flowing; There is radial compression to strengthen intensity of cooling to ignition tip 8 outer walls; Make ignition tip 8 obtain more effective cooling, the temperature gradient that the gas in the ignition tip 8 radially forms is bigger, makes the hot compression effect of electric arc more effective; General protective cover 3 is shorter, only ignition tip 8 is protected in 1/2nd, if reason is that whole rifle head 2 cooling effects are bad, protective cover 3 lengthenings can hold can't stand and explosion easily.At last, as shown in Figure 6, the cutting gun handle is designed to whole circular arc band three roads finger concave arc shape, and adopts touch-switch 12.Utilize bionic principle, according to the basic structure of human body palm skeleton, thumb touch touch-switch 12, and all the other four finger natures are fitted with the finger concave arc; 360 ° of ball-type knots of handle afterbody band can not drive cable when making the swing handle.Hold the sense comfortable, fatigue strength is light, makes the operator better brought into play in use.
Those skilled in the art's simple change and replacement all are within protection scope of the present invention in this area.
