Abstract
A carbon arc air gouging torch nozzle with circumferential air supply is applied to carbon arc air gouging metal cutting and characterized in that the upper end part of a nozzle core is provided with a carbon rod fixed outer thread and the lower end part thereof is provided with a central tube. The carbon rod fixed outer thread is provided with a carbon rod fixed nut; the center of the nozzle core is provided with a carbon rod installation hole; and the carbon rod installation hole is a through hole. A nozzle is fixed on the outer wall of the nozzle core, wherein the shape of the nozzle is as follows: the upper end of the nozzle is a cylindrical tube and the lower end thereof is a conical tube. A ring-shaped gap with the width of 0.5-1.5 mm is arranged between the lower end of the conical tube of the nozzle and the outer wall of the central tube of the nozzle core. An air inlet is arranged on the cylindrical tube wall of the nozzle. The carbon arc air gouging torch nozzle with circumferential air supply has the effects that the air supply volume is uniform and the cutting speed is high; the air supply volume is large, thereby being capable of improving the cutting quality; and the operation is convenient.
Description
Technical field
The utility model relates to golden cutting technique field, and particularly a kind of instrument that utilizes the carbon arc air gouging cutting metal is a kind of carbon arc air gouging cutting nozzle of circumferential air-supply.
Background technology
At present, in the Metal Cutting technical field, often use a kind of carbon arc air gouging cutting metal.The principle of carbon arc air gouging cutting metal is, utilizes electric arc and compressed air simultaneously workpiece to be carried out the instrument of arc gouging, and electric arc makes the workpiece high temperature melting, the metal after compressed air blows away and dissolves.Have multiplely about the carbon arc air gouging instrument, the structure different principle is basic identical.As the Chinese patent publication number is CN2587569, and a kind of carbon arc air gouging torch is provided.The Chinese patent publication number is CN201086171, discloses a kind of carbon arc air gouging mouth.Publication number is CN2933681, discloses a kind of carbon arc air gouging rifle head.
The carbon arc air gouging cutting torch mouth that uses is the single face air-supply now, and there is following shortcoming in this cutting torch:
1. uneven air influences cutting speed.
2. air output is little, and welding slag is deposited near the weld bond, influences cut quality.
3. it is not easy to operate to operate unskilled person.
The utility model content
The purpose of this utility model is: a kind of carbon arc air gouging torch mouth of circumferential air-supply is provided, makes carbon arc can have the metal after enough wind-force will dissolve to blow away on every side, reach the purpose of cutting metal.Improve the operating efficiency of carbon arc air gouging, reduce the use difficulty of carbon arc air gouging instrument.Overcome present carbon arc air gouging instrument uneven air simultaneously, influence the deficiency of cutting speed;
The technical solution adopted in the utility model is: the carbon arc air gouging torch mouth of circumferential air-supply, mainly form by nozzle, nozzle core and carbon-point hold-down nut, it is characterized in that: nozzle core is that ladder is cylindric, and there is fixedly external screw thread of carbon-point the upper end of nozzle core, and there is central tube the bottom of nozzle core.Fixedly on the external screw thread carbon-point hold-down nut is arranged at carbon-point.At the center of nozzle core a carbon-point installing hole is arranged, the carbon-point installing hole is a through hole.On the outer wall of nozzle core, external screw thread is arranged, be fixed with nozzle on the external screw thread of nozzle core.Its shape of nozzle is that the upper end is a cylindrical drum, and the nozzle lower end is a conical tube.There is internal thread the cylindrical drum upper end of nozzle and is fixed on the external screw thread of nozzle core outer wall.The annulus that 0.5～1.5 mm wide is arranged between the lower end of nozzle conical tube and the central tube outer wall.On the cylinder barrel of nozzle, fresh air inlet is arranged.Fresh air inlet can connect the pressure-air pipeline.Pressure-air enters from fresh air inlet, from the ejection of annular gap crack, blows away the metal after dissolving during work.
Carbon-point fixedly external screw thread is a tapered thread, and carbon-point fixedly has four gap longitudinally on the external screw thread, when the carbon-point hold-down nut screws, can make the fixing externally threaded center-hole diameter of carbon-point dwindle the chucking carbon-point; When the carbon-point hold-down nut unscrews, can make the fixing externally threaded center-hole diameter of carbon-point recover normal, unclamp carbon-point, can adjust the length of carbon-point.
The beneficial effects of the utility model: the utility model circumferentially carbon arc air gouging torch mouth of air-supply has following advantage:
1. air output is even, and cutting speed is fast.
2. air output is big, can improve cut quality.
3. operation is very easy, and the beginner who has just begun to learn carbon arc air gouging also can operate easily.
Description of drawings
Fig. 1 is the circumferentially carbon arc air gouging torch mouth structure generalized section of air-supply of the utility model.
Among the figure, 1. nozzle, 2. nozzle core, 3. carbon-point hold-down nut, 4. carbon-point installing hole, 5. fresh air inlet, 6. central tube, 7. annular gap.
The specific embodiment
Embodiment 1: with carbon-point installing hole 4 diameters is that the carbon arc air gouging torch mouth of 6.5 millimeters circumferential air-supply is an example, and the utility model is described in further detail.
Consult Fig. 1.The utility model is the carbon arc air gouging torch mouth of air-supply circumferentially, mainly is made up of nozzle 1, nozzle core 2 and carbon-point hold-down nut 3.Nozzle core 2 is that ladder is cylindric, and there is fixedly external screw thread of carbon-point the upper end of nozzle core 2, the tapered thread that external thread diameter is 12 millimeters, 15 millimeters of length.It is 3 millimeters gap that carbon-point fixedly has longitudinally four width on the external screw thread.There is central tube 6 bottom of nozzle core 2, with nozzle core 2 be one.10 millimeters of central tube 6 external diameters, 6.5 millimeters of internal diameters, 66 millimeters of length.Fixedly on the external screw thread carbon-point hold-down nut 3 is arranged at carbon-point.Carbon-point hold-down nut 3 is tapered cup nuts.It is through hole (6.5 millimeters of diameters) that a carbon-point installing hole 4, carbon-point installing hole 4 are arranged at the center of nozzle core 2, and with central tube 6 UNICOMs.
