Abstract
The utility model relates to a cutting torque for a numerical control flame cutting machine and the numerical control flame cutting machine. The numerical control flame cutting machine comprises a cutting workbench, a cutting machine crossbeam, and the cutting torque arranged on the crossbeam. The cutting torque comprises a cutting torque bracket and a cutting tip, wherein an insulating connection mechanism is arranged on the cutting torque bracket; the cutting tip is a conductor, is arranged on the insulating connection mechanism and is connected with an igniting output terminal of an igniting circuit; and the cutting workbench is connected with the other output terminal of the igniting circuit. During operation, the control switch of the igniting circuit is controlled to initiate discharge between a section around the bottom air holes of the cutting tip and a steel plate base material to generate tubular ignition arc when the cutting torque reaches a work position. Since the arc is located on the spray path of an inflammable gas and a plurality of ignition sources are formed around the gas flow, the inflammable gas can be ignited immediately to eliminate the ignition failure, thereby achieving high success rate for one-time ignition. The numerical control flame cutting machine has no need for additional ignition device and has simple structure and reduced cost.
Description
Technical field
The utility model relates to a kind of cutting torch and NC flame cutting machine of NC flame cutting machine.
Background technology
At present, what the sparking mode of NC flame cutting machine was commonly used has two kinds, 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, during the igniting cutting, needing earlier, the operation firing device makes it to produce a little flare, then fuel gas sprays from cutting torch, the generation cutting flame is just ignited after running into little flare, at this moment also need to knock out again the little flare of firing device, this ignition method that ignites is more original, and 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 sprays from cutting torch is very fast, the situation that igniting several times could be lighted combustion gas often occurs, an ignition success rate of this point type incendiary source can not reach absolutely.
The utility model content
The purpose of this utility model provides the high NC flame cutting machine cutting torch of an a kind of ignition success rate.
Another purpose of the present utility model provides an a kind of high NC flame cutting machine of ignition success rate.
For realizing first purpose, the utility model adopts following technical scheme: the NC flame cutting machine cutting torch, comprise cutting torch support and cutting torch, described cutting torch is an electric conductor, be used for being connected with the igniting output stage of a firing circuit, the cutting torch support is provided with insulation bindiny mechanism, and cutting torch is installed in the insulation bindiny mechanism.
Described 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 by a cutting torch clamper, and the cutting torch clamper is an electric conductor.
For realizing second purpose, the utility model adopts following technical scheme: NC flame cutting machine, comprise cutting workbench, cutting machine crossbeam and be installed on cutting torch on the cutting machine crossbeam, cutting torch comprises cutting torch support and cutting torch, the cutting torch support is provided with insulation bindiny mechanism, and cutting torch is installed in the insulation bindiny mechanism, and cutting torch is an electric conductor, cutting torch is connected with an igniting output stage of a firing circuit, and the cutting workbench is connected with another output stage of described firing circuit.
Described 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 by a cutting torch clamper, and the cutting torch clamper is an electric conductor.
Described firing circuit comprises high-voltage pulse power source.Described 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 utility model 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 arrives 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 utility model does not need to dispose igniter in addition, and is simple in structure, and saved cost.
