Abstract
The invention relates to a numerical control flame cutting machine and a cutting torch thereof. The numerical control flame cutting machine comprises a cutting worktable, a cross beam of the cutting machine, and the cutting torch mounted on the cross beam of the cutting machine; the cutting torch comprises a cutting torch support and a cutting nozzle; an insulating connection mechanism is arranged on the cutting torch support; the cutting nozzle is mounted on the insulating connection mechanism, is a conductor, and is connected with an ignition output pole of an ignition circuit; and the cutting worktable is connected with the other output pole of the ignition circuit. A control switch of the ignition circuit is operated after the cutting torch reaches the work position during the working, discharge phenomena can be generated among the peripheral parts of gas pores at the bottom end of the cutting nozzle and steel plate mother materials, so that a tubular ignition electric arc can be generated; since the electric arc is located on a jetting path of the flammable gas flow, and a plurality of ignition sources formed around the gas flow, so that the flammable gas can be immediately ignited, the phenomenon that the gas can not be ignited can be eliminated, and the success rate of the onetime ignition is high. The invention has the advantages that an additional ignition device is not required to be configured, the structure is simple and the cost can be saved.
Description
Technical field
The present invention relates to a kind of NC flame cutting machine.
Background technology
At present, what the sparking mode of NC flame cutting machine was commonly used has two kinds, and a kind of is that a firing device is installed on its cutting torch support; The burner of firing device is positioned at the next door of Cutting nozzle for cutting torch, and during the igniting cutting, needing earlier, the operation firing device makes it to produce a little flare; Then fuel gas sprays from cutting torch; At this moment the generation cutting flame that after running into little flare, just ignited also need knock out the little flare of firing device again, and this ignition method that ignites is more original; Igniting is slow, complicated operating process; Another kind of sparking mode is that an electronic ignition device is installed on its cutting torch support; Because the firing tip of this electronic ignition device is positioned at the next door of Cutting nozzle for cutting torch; During igniting, near the fuel gas air-flow that from cutting torch, sprays, only produce an incendiary source, the fuel gas air velocity that in addition from cutting torch, sprays is very fast; Often appearances needs the situation that igniting several times could be lighted combustion gas, and an ignition success rate of this point type incendiary source can not reach a hundred per cent.
Summary of the invention
The purpose of this invention is to provide an a kind of high NC flame cutting machine of ignition success rate.
The present invention adopts following technical scheme: NC flame cutting machine; Comprise cutting workbench, cutting machine crossbeam and be installed on the cutting torch on the cutting machine crossbeam, cutting torch comprises cutting torch support and cutting torch, and the cutting torch support is provided with insulation bindiny mechanism; Cutting torch is installed in the insulation bindiny mechanism; Cutting torch is an electric conductor, and cutting torch is connected with an igniting output stage of a firing circuit, and the cutting workbench is connected with another output stage of said firing circuit.
Said insulation bindiny mechanism comprises insulator, and insulator one end is connected with the cutting torch support, and the other end is connected with cutting torch.
Cutting torch is installed in the other end of insulator through a cutting torch clamper, and the cutting torch clamper is an electric conductor.
Said firing circuit comprises high-voltage pulse power source.Said cutting torch is connected with the positive pole of high-voltage pulse power source, and the cutting workbench is connected with the negative pole of high-voltage pulse power source.The minus earth of high-voltage pulse power source.
The present invention utilizes cutting torch to be connected with an igniting output stage of firing circuit as electrode body, and the steel plate mother metal that is seated on the cutting workbench is connected with another igniting output stage of firing circuit, during work; After cutting torch arrived the operating position, the gauge tap of operating point ignition circuit just can cause electric discharge phenomena between position around the pore of cutting torch bottom and the steel plate mother metal; Produce the tubulose ignition arc, at this moment, if there is fuel gas from the cutting torch pore, to spray; The fuel gas air-flow promptly can be surrounded by the tubulose ignition arc; Because this electric arc is on the path of combustible gas stream ejection, and has formed a plurality of incendiary sources around air-flow, so fuel gas is lighted at once; Eliminated the phenomenon of putting not, an ignition success rate height.The present invention does not need to dispose igniter in addition, and is simple in structure, and practiced thrift cost.
