Description
One, technical field
The utility model relates to a kind of burning torch, relates in particular to a kind of plasma burning torch.
Two, background technology
The plasma burning torch that utilizes plasma to cut in the market mainly comprises nozzle, electrode, electrode tip holder, water inlet pipe, outlet pipe, little water pipe, air inlet pipe, flow splitter, insulating case, interior rifle body and outer rifle body; Little water pipe is located in the electrode tip holder of electrode rear end and communicates with water inlet pipe, outlet pipe; This plasma cutting torch is owing to be by water inlet pipe, outlet pipe and little water pipe cooling water to be imported in the plasma cutting-torch electrode is cooled off, and its electrode cooling effect is relatively poor to make that the useful life of electrode is shorter.
Three, summary of the invention
At above-mentioned shortcoming, the purpose of this utility model is to provide a kind of plasma burning torch that can improve electrode cooling effect and useful life.
Technology contents of the present utility model is a kind of plasma burning torch, nozzle, electrode, electrode tip holder, water inlet pipe, outlet pipe, little water pipe, air inlet pipe, flow splitter, insulating case, interior rifle body and outer rifle body; It is characterized by outside that rifle body front end is connected with a pressure cap by a swivel nut, be provided with a compacting ring between pressure cap front end and the nozzle, form a cooling water cavity between pressure cap, compacting ring and the nozzle; Be provided with a water guide cover in pressure cap, the water guide cover is connected by penstock and little water pipe, and the water guide cover is communicated with by water output duct and outlet pipe.
The profile of plasma burning torch of the present utility model is divided directly handle and curved two kinds of forms, directly being applicable to numerical control automatically or the auto-manual system cutting, curved practical with manually or the auto-manual system cutting.
The advantage that the utility model is compared with prior art had is:
1, adopts the type of cooling of tandem double-water internal cooling, simultaneously electrode and nozzle are effectively cooled off, improve electrode cooling effect and useful life.
2, more advantages of simple, handled easily and use of structure of the present utility model.
Four, Figure of description
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Five, specific embodiment
As depicted in figs. 1 and 2, a kind of plasma burning torch, nozzle 1, electrode 2, electrode tip holder 3, little water pipe 4, water inlet pipe 5, outlet pipe 6, air inlet pipe 7, flow splitter 8, insulating case 9, interior rifle body 10 and outer rifle body 11; Flow splitter 8 is mounted on nozzle 1 rear end and air inlet pipe 7 communicates; Interior rifle body 10 is installed in flow splitter 8 rear ends; Water inlet pipe 5, outlet pipe 6 and air inlet pipe 7 are arranged in the outer rifle body 11, are filled with epoxy resin in the rifle body 11 outside; Water inlet pipe 5 and little water pipe 4 are communicated with; Little water pipe 4 is arranged in the electrode tip holder 3 of electrode 2 rear ends; Rifle body 11 front ends are connected with a pressure cap 13 by a swivel nut 12 outside, are provided with a compacting ring 14 between pressure cap 13 front ends and the nozzle 1, form a cooling water cavity 15 between pressure cap 13, compacting ring 14 and the nozzle 1; Be provided with water guide cover 16 in pressure cap 13, water guide cover 16 is connected by penstock 17 and little water pipe 4, and water guide cover 16 is communicated with by water output duct 18 and outlet pipe 6; Be provided with striking line 19 in the rifle body 11 outside.
Operation principle of the present utility model is:
1, air-channel system
The air feed of ion gas: the helical intake of the ion gas of compression in air inlet pipe 7 → flow splitter 8 forms rotation gas → nozzle 1, forms the high-temperature plasma arc and spray from nozzle bore under the effect of plasma power supply.
2, water-cooling system
The cooling water of electrode, nozzle through water inlet pipe 5 → electrode tip holder 3 → air inlet pipe 7 → cooling electrode 2 → penstock 17 → water guide cover 16 → cooling water cavity 15 → cooling jet 1 → water guide cover 16 → water output duct 18 → outlet pipe 6, is finished a circulation cooling procedure thus.
3, electric power system:
A, burning torch is provided main power source (negative electrode) through water inlet pipe 5 → electrode tip holder 3 → electrode 2, under the guiding of untransferable arc and ion gas, produce transferred arc and form required cutting current with the main power source that is connected workpiece is anodal;
B, auxilliary power supply (anode striking power supply) produce loops with electrode 2 and form the plasma untransferable arcs under the effect of striking line 19 → swivel nut 12 → pressure cap 13 → compacting ring, 14 → nozzle 1 at striking voltage, for the generation of transferred arc provides necessary condition.
