Abstract
The utility model discloses a need not high frequency high pressure striking, adopt low pressure direct current striking and cutting, the nozzle end of cutting torch pastes the work piece when cutting striking and one downwards relaxs according to promptly gently, just can lead into the low pressure direct current striking cutting machine cutting torch of cutting with plasma arc during the separation. The plasma arc discharge device is characterized in that the inner wall of the inner-layer metal conductor is connected with an electrode for emitting plasma arc, a circulating air flow groove is arranged outside the inner-layer metal conductor, and three tangential air flow grooves are arranged at the top end of the inner-layer metal conductor and circularly wound. The cutting torch has the advantages of saving energy and materials (saving raw materials by 60 percent), improving the service life of the cutting torch by about 10 times compared with the cutting torch of a common cutting machine, and the like.
Description
The utility model relates to a kind of low-voltage direct striking cutting torch, the cutting machine of low-voltage direct striking specifically cutting torch.
The plasma cutting all can't be got rid of the technical problem of high frequency, high-voltage arc strike for a long time, because the fault rootstock of cutting machine and plasma arc cutting torch comes from the damage of puncture aspect, the damage root of electric wiring comes from high-frequency and high-voltage, the source of damage more than 95% of cutting torch be do not become when coming from the high-frequency and high-voltage striking or striking not good and cause.The infiltration of high-frequency and high-voltage also is easy to cause the damage of the electronic device in the machinery equipment, and complete machine is damaged, and high-frequency and high-voltage also can be by the contiguous electronic equipment of power supply radiation interference, work as computer, microcomputer, so, for a long time China in the program control field of cutting machine always slowly not before.
The purpose of this utility model then is the problem at above-mentioned existence, has designed a kind of high-frequency and high-voltage striking that need not this machine of cutting machine, and can reach the low-voltage direct striking cutting machine cutting torch of energy-conservation joint material.It is to any electronic instrument and equipment is noiseless and damage, and can with various microcomputers and the supporting use of program control numerical control device, make the cutting machine life-span that nearly 10 times prolongation be arranged.
The utility model technical solution:
A kind of by body insulator 9; internal layer; outer layer metal electric conductor 5; 8; the electrode 2 of hafnium filament 10 is housed; insulation separation sleeve 3; nozzle 1; the low-voltage direct striking cutting machine cutting torch that protective sleeve 4 is formed; it is characterized in that inner layer metal electric conductor 5 inwalls connect the electrode 2 of emission plasma arc; there is the circulation airflow groove inner layer metal electric conductor 5 outsides; have three tangential gas flow grooves and annular to curl up at inner layer metal electric conductor 5 top ends, middle level metallic object 6 cooperates with spring 7 between centers, and there is axial cold gas chute metallic conductor 6 outsides in middle level; separation sleeve 3 is inserted in inner layer metal electric conductor 5 tops; nozzle 1 is inserted on the separation sleeve 3, and 1 two at electrode 2 and nozzle are isolated extremely mutually, and outer layer metal electric conductor 8 one ends are connected with the pneumoelectric pipe by inner layer metal electric conductor 5 tops; the other end links to each other with protective sleeve 4, and protective sleeve 4 links to each other with nozzle 1.
Advantage of the present utility model:
The utility model need not the high-frequency and high-voltage striking, adopts low-voltage direct striking and cutting, and the nozzle end of cutting torch is sticked workpiece downwards gently one by loosening during cutting arc-striking, just plasma arc can be drawn to become during separation and cuts.That this cutting torch has is energy-conservation, joint material (economizing in raw materials 60%), and characteristics such as structure optimization improve nearly 10 times than the cutting torch life-span of general cutting machine.
Fig. 1 is the utility model structural representation.
Below in conjunction with accompanying drawing the utility model is further described:
Electrode 2 one ends are equipped with hafnium filament 10, the other end is connected with inner layer metal electric conductor 5 inwalls, the cutting operating voltage is added to electrode 2 by metallic conductor, it is indoor that air-flow flows to outside air drain by outer layer metal electric conductor 8 by inner layer metal electric conductor 5 top endoporus, indoor gas divides two-way, one the tunnel enters the tangential rotating room of inner layer metal electric conductor 5 outside leading portions, forms the whirlpool surrounding electric poles and enters electrode chamber, discharges through nozzle 1 internal orifice.The gas that (electrode and nozzle the two poles of the earth) are flow through when cutting torch collides be the original molecule state insulator (because since in the free factor effect gas in the gas external world free electron that produces few, thereby the conductance of gas medium is also less, so be in insulator state).(electrode separates with nozzle the two poles of the earth) gas is in the arc column when cutting torch collides the moment of separating; outside under the effect of electric field along with the increase of applied voltage; the dielectric charge particle is more and more; when applied voltage increases to a certain degree; air gap develops into the electron avalanche phenomenon by charged particle because of liberation; and number of charged particles is increased severely; thereby cause puncturing; qualitative change has taken place in the gas in the arc column at this moment; the atom of some of them neutrality has been emitted electronegative electronics; and qualitative change is an ionic condition; the particle that this charged son has been arranged; just possessed conductive capability; in ionized gas; the neutrality that all presents electricity in its each macroscopical zone; this gas in the arc column has formed plasma; and go out through jet hole with very fast rotary speed; and the gas of spray Zi, one of the lunar mansions mouth around along the wall limit; because the gas qualitative change in the arc column is a plasma; gas along wall spreads applied voltage around the nozzle and make; charged particle in the discharge channel again can be (compound because of playing liberation; diffusion etc.) disappear; cause the conductance of gas air gap to reduce again; so the electrolytical insulating properties of gas can be recovered; make nozzle around wall, form an insulating properties better protect air film; make nozzle obtain strong protection; and operating current forms a galvanic circle to electrode by arc column through metallic conductor; three big effects in electrode chamber, have been formed by the arc column current lead-through; i.e. " mechanical compress effect "; " thermal pinch "; " magnetic pinch "; because above-mentioned Fundamentals make the plasma column concentration of energy, penetrate with superfine flame cylindricality attitude.Another road gas enters inner layer metal conductor 5 external shafts to the cold gas chute; through insulation separation sleeve 3 outer flow through nozzle 1 outside; in protective sleeve 4, the hot temperate zone on the nozzle is gone out with very fast speed; therefore; the utility model all adopts the low-voltage direct mode from striking to cutting, thereby makes the life-span of cutting plasmatorch improve nearly 10 times.
The plasma cutting-torch of the utility model low-voltage direct striking; import and homemade raw material have been adopted; mainly be to have adopted the copper alloy conductive material; insulating material adopts import SMC, epoxy adhesive plaster etc.; nozzle, protective sleeve adopt the white pottery porcelain; insulating spacer adopts epoxy material or white pottery porcelain, and gas adopts cheap compressed air.
