Description
Technical field the utility model relates to a kind of device that is applied to cut different shape workpiece (as sheet material), belongs to the B23K7/02 class.
Background technology is before the utility model, the oxyacetylene metal-cutting rifle that is used to cut the employed oxyacetylene metal-cutting rifle of straight or special-shaped workpiece (as steel plate etc.) and all is manual operations, lights a fire by hand by the operator, use this oxyacetylene metal-cutting rifle can realize the purpose of cuts sheet material, also get used to this operation to a certain extent; But its weak point mainly is inconvenience, if security incident appears in misoperation easily.So the operator wishes to have a kind of oxyacetylene metal-cutting rifle that does not need the manual firing and can light a fire automatically to be used for operation field.
Summary of the invention task to be solved in the utility model provides the safe oxyacetylene metal-cutting rifle that a kind of applicability can not occur security incident again by force, not need manual firing's the continuous igniting of electronics, this electronics continuity point fire safety oxyacetylene metal-cutting rifle still utilizes the original manual firing's oxyacetylene metal-cutting rifle rifle body that uses, only a direct-current discharge device is installed at the handle place of manually-operated rifle body, the mist nozzle head is redesigned and changes, the electrical discharge wire of drawing from the direct-current discharge device---be that ignition lead is installed on the oxygen mouth conduit of mist nozzle head.
For finishing the technical scheme that above-mentioned task adopts be: this electronics continuity point fire safety oxyacetylene metal-cutting rifle is made up of rifle body, electronic striking device and mist nozzle.The rifle body comprises that still oxygen, acetylene suction nozzle, turn-knob switch and their conveyance conduit and oxygen, acetylene converge first-class; The electronic striking device comprises discharge transformer, discharge line plate, dc-battery and switch; The mist nozzle comprises cap mouth connecting filament mouth, insulated porcelain sleeve, oxygen mouth, oxygen muzzle pipe etc., and successively they are dressed up an integral body, draw an electrical discharge wire (being ignition lead) from the discharge transformer of electronic striking device and be affixed on the oxygen mouth conduit of mist nozzle through the ceramic conduit on the coupling nut.
Adopt the electronics continuity point fire safety oxyacetylene metal-cutting rifle of as above technical scheme making to compare with the manual firing's oxyacetylene metal-cutting rifle that uses in the past, its advantage is:
Compact conformation, manufacturing process is simple, and is easy to use, and operating personnel need not carry the purpose that any firing tools just can be realized continuous safety ignition, are specially adapted to work high above the ground personnel's safety operation.
Description of drawings Fig. 1 is the structural representation of electronics continuity point fire safety oxyacetylene metal-cutting rifle described in the utility model, also is specification digest accompanying drawing of the present utility model;
Fig. 2 is the direct-current discharge device conspectus that is installed on handle inside shown in Figure 1.
Fig. 3 is that the F-F ' of Fig. 4 is to cross-sectional schematic;
Fig. 4 is marked oxygen and acetylene gas mixture nozzle arrangements enlarged diagram shown in the A by Fig. 1.
The specific embodiment is described in further detail the specific embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1,1 for oxygen advances mouth, and 2 for acetylene advances mouth, with the rubber packing appendix they is linked to each other with oxygen, acetylene source of the gas.Handle 3 is installed on oxygen, the acetylene conveying pipe, in handle 3, be equipped with direct-current discharge device as shown in Figure 2, the positive pole of dc-battery 21 is connected with a point of discharge line plate 22 through switch 6, negative pole is connected with the b point of discharge line plate 22, draw a line from the c point of discharge line plate 22 and be connected, draw an ignition lead 8 from discharge transformer 23 with discharge transformer 23.Wherein switch 6 is a point driving switch, and it is installed on the shell of handle 3, and ignition lead 8 is connected with lower cap mouth 18 through the porcelain tube 20 that the mixing head 9 of oxygen, acetylene passes on the coupling nut 10.Coupling nut 10 is threaded in and converges a lower end of 9, tighten coupling nut 10 and converge 9 cap mouth connecting filament mouth 12 is adjacent, make and converge an oxygen channel in 9 centres 11 ' communicate with the oxygen channel 14 in cap mouth connecting filament mouth 12 centres, making can the smooth and easy oxygen channel 14 that enters cap mouth connecting filament mouth 12 from the oxygen that converges a oxygen channel 11 on 9 ' come, can not make oxygen channel 11 ' in oxygen leakage go out.Around the top of cap mouth connecting filament mouth 12, evenly be processed with acetylene passage 13 (being generally 6).Last cap mouth 15 is threaded with the bottom of cap mouth connecting filament mouth 12, and this connects version partly as shown in Figure 3, be that cap mouth connecting filament mouth 12 is not a full circle cylindrical body herein, but the space is left on both sides, so that from then on the acetylene of coming from acetylene passage 13 pass through the space.The first half of porcelain tube 16 is threaded with the lower end of last cap mouth 15.Oxygen mouth 17 usefulness copper materials are made, the upper end of oxygen mouth 17 is threaded with the lower end of cap mouth connecting filament mouth 12, tightly be enclosed within the bottom of oxygen mouth 17 with the oxygen mouth conduit 19 of ceramic material, it plays insulating effect to the lower end of oxygen mouth 17, lower cap mouth 18 is threaded in the lower end of insulated porcelain sleeve 16, the upper end of lower cap mouth 18 is cylindrical, and the lower end is conical.The oxygen channel 14 in oxygen mouth 17 centres ' be conical, the more little then pressure of the bore at the oxygen outlet place is just big more.
When operating personnel use electronics continuity point fire safety oxyacetylene metal-cutting rifle described in the utility model, oxygen is advanced mouth 1 to be advanced mouth 2 with acetylene and connects appropriate, and open acetylene hand switch 4 and oxygen hand switch 5, regulate hand switch 7, make oxygen and acetylene from separately pipeline enter enter again after converging 9 acetylene passage 11 and oxygen channel 11 ', when feel has gas to come out to the port of export at oxygen mouth 17, open the switch 6 on the handle 3, battery 21 power supplies, because ignition lead 8 is connected on the shell of lower cap mouth 18, so between oxygen mouth 17 and lower cap mouth 18, produce the continuous electric spark, ignite from the acetylene gas of acetylene passage 13.Regulate oxygen, mix the purpose of flame temperature that improves burning gases with acetylene to realize that cutting is in kind from oxygen channel 14 ' come.Behind the cutting end-of-job, close the air inlet switch of oxygen and acetylene, cutting work stops.
