Abstract
The utility model discloses a need not high frequency high pressure striking, adopt low pressure direct current striking and cutting, the nozzle of cutting torch pastes the work piece when cutting striking and presses to the next gently, just can form the low pressure direct current striking plasma cutting torch of plasma arc and cutting during the collision separation. The electrode is extended into the part of the isolating sleeve, the diameter of the outer edge of the electrode shrinks in a step shape from top to bottom, and the section of the inner hole of the nozzle shrinks in a step shape corresponding to the diameter of the outer circle of the electrode. Compared with the cutting torch of a common cutting machine, the service life of the cutting torch is improved by about 10 times.
Description
The utility model relates to a kind of low-voltage direct striking cutting torch, the plasma cutting-torch of low-voltage direct striking specifically.
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 plasma 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 life-span of cutting machine and cutting torch that nearly 10 times raising be arranged.
The utility model technical solution:
A kind of by body insulator 11; internal layer, outer layer metal electric conductor 9; 7; nozzle 1; the electrode 2 of hafnium filament 12 is housed; insulation separation sleeve 3; insulation wireway 4; protective sleeve 6; the low-voltage direct striking plasma cutting-torch that conduction tracheae 10 is formed is characterized in that spring 5 collides the two poles of the earth (two opposite poles of electrode and nozzle) with up and down cover 8 by separation sleeve 3 and separates the part that electrode 2 prolongations enter the separation sleeve 3 that insulate; its outside diameter is stairstepping from top to bottom and shrinks, and nozzle 1 bore profile is with the corresponding ladder of electrode 2 outside diameters shrinks.
Advantage of the present utility model:
The utility model need not the high-frequency and high-voltage striking, and the nozzle end of cutting torch is sticked mutual part downwards gently one by loosening when adopting the low-voltage direct striking with the cutting cutting arc-striking, just plasma arc can be drawn to become when collision separates and cuts.Originally cut, joint material (economizing in raw materials 60%) energy-conservation apart from having, characteristics such as structure optimization improve nearly 10 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:
The characteristics of the utility model low-voltage direct striking plasma cutting-torch are: electrode 2, nozzle 1 the two poles of the earth (opposite sex) can be collided and separate automatically, inner layer metal electric conductor 9 inwalls connect the electrode of emission plasma arc, there is the air drain chamber of circulation inner layer metal electric conductor 9 outsides, and front end has tangential rotation form whirlpool surrounding electric poles to enter electrode chamber through nozzle 1 outlet discharge.Up and down body 8 cooperates with spring 5 between centers; there is axial air cooling duct inner layer metal electric conductor 9 outsides; and the insulating spacer 3 that links to each other on inner layer metal electric conductor 9 tops; the other end of insulating spacer 3 links to each other with nozzle 1, and the two poles of the earth also isolate, and inner layer metal electric conductor 9 tops communicate with contact tube 10; outer layer metal electric conductor 7 one ends link to each other with protective sleeve 6; nozzle with cutting torch during striking sticks work,, just plasma arc can be formed and cutting during separation by promptly loosening to next.
The utility model low-voltage direct striking plasma arc cutting torch; import and homemade raw material have been adopted; mainly adopted the copper alloy conductive material; insulating material adopts import SMC, epoxy adhesive plaster etc.; nozzle, insulating spacer material adopt epoxy material or white pottery porcelain; protective material adopts the white pottery porcelain, and gas adopts cheap compressed air.
Claims (2)
1, a kind of by body insulator 11, inside and outside layer metallic conductor 9,7; nozzle 1 is equipped with the electrode 2 of hafnium filament 12, insulation separation sleeve 3; insulation wireway 4, protective sleeve 6, the low-voltage direct striking plasma cutting-torch that conduction tracheae 10 is formed; it is characterized in that spring 5 is enclosed within on the metallic object 7; movable sleeve 8 one ends connect spring 5, and the other end connects separation sleeve 3, and separation sleeve 3 other ends connect nozzle 1; electrode one end connects metallic object 8, and the other end is in the centre of separation sleeve 3, nozzle 1.
2, low-voltage direct striking plasma cutting-torch according to claim 1 is characterized in that electrode 2 in the middle of separation sleeve 3, and its outside diameter is shunk through the conical surface by equal-diameter part from top to bottom, and nozzle 1 diameter of bore is shunk through the conical surface by isometrical district from top to bottom.
