Abstract

The utility model discloses a welding torch with electronic ignitor provided with an electronic ignitor and an assident mixed gas ejecting device. The electronic ignitor is ignited to light up the assident ejecting device to eject the mixed gas to ignite the welding and cutting gun so as to reach the purpose of igniting automatically. The utility model solves the problem that the ignition is difficult and the operation is not convenient after using the electronic ignitor, has the advantages of energy saving and having high production efficiency, and is the favorable welding and cutting tool to weld and cut.

Description

Welding torch with electronic ignitor

The utility model relates to the weldering of present industrial use, the igniting of burning torch.The utility model is with the combining of electronic lighter and weldering, burning torch, and lights the gaseous mixture of self, the solder cutting gun that ignites, thus reach automatic igniting purpose.It is the improvement on original various old-fashioned weldering, burning torch basis.

Weldering of the prior art, burning torch are the igniting of artificial use match, and this is energy-conservation and use and all exist many shortcomings, often since first and second igniting not cause unnecessary waste to bring many troubles or the like with giving in the operation.

Electronics auto-ignition welding of the present utility model, burning torch design specially for solving above shortcoming, thereby have improved the deficiencies in the prior art.

Design of the present utility model is to improve to form on the basis of various old-fashioned weldering, burning torch.In original weldering, burning torch handle, install an electronic lighter additional, draw high-voltage line, rotor, see accompanying

drawing

1,1. 3. 2., and below weldering, burning torch mixture pipe, install a gaseous mixture switch, mixture pipe, nozzle head additional, 4. 5. 6., gaseous mixture drawn with high pressure, spark by gaseous mixture switch, mixture pipe, nozzle head meet and light, thereby ignite weldering, burning torch, reach automatic igniting purpose.

For reaching the optimum igniting effect, nozzle head and rotor preferably extend to the arc welding gun head afterbody, and burning torch extends to 3/4 or 4/5 position of burning torch mixture pipe; Its nozzle head center line and weldering, burning torch head center line intersection point should be within 10 to 20 millimeters.Electronic lighter can adopt high-effect electronic lighter, is preferably continuous ignition.High-voltage line adopts general high-voltage line, can not leak electricity when requirement contacts with metal tube.The rotor body is ceramic making preferably, draws an ignition pin.Mixture pipe can adopt 6 millimeters copper pipes of φ, shower nozzle, rotor under the prerequisite that does not influence electrion, as close as possible weldering, burning torch pipe.

During use, at first open the gaseous mixture switch, push away (or pressing down) electronic ignition switch when then respectively oxygen, acetylene being opened in right amount forward, tracheae to be mixed is got angry and the weldering of igniting.Again the gaseous mixture switch is shut behind the burning torch.Through test, moderate at oxygen, acetylene, oxygen is on the high side, and under acetylene three kinds of situations on the high side, the efficent electronic igniter all can be lighted weldering, burning torch in time.

Describe in detail bright again:

1, blender switch and position: blender switch structure and acetylene torch switch structure are similar, its position is installed in weldering, burning torch mixture pipe below, see that accompanying drawing 2A-A cuts open, at first lengthening weldering, burning torch mixture pipe length, see accompanying drawing 2,8., require to arrange till the following gaseous mixture switch, switch valve doorway central point is 9. with 8. 5 to 8 millimeters of afterbody level reaches of mixture pipe, 8. move 15 millimeter below the center line with mixture pipe, 3. 5. mixture pipe reach high-voltage line under requiring to arrange, and is convenient to again till dismounting weldering, the burning torch mixture pipe.10. the gaseous mixture air admission hole can take vertical drilling, considers the outflow of being convenient to gaseous mixture, and the aperture can be slightly larger than the internal diameter of weldering, burning torch mixture pipe, perhaps to the 8. afterbody angle that tilts of mixture pipe, sees that 10. A-A cuts open, and mixture pipe is 5. with screw thread and body

Connect, mixture pipe can adopt 6 millimeters copper pipes of φ.

2, electronic lighter and installation: because electronic lighter is various in style on the market at present, this drawing is an example with the electronic lighter in the at present comparatively popular electronic lighter, divide two kinds on battery and no battery arranged, 1. be installed between two air inlet pipe as accompanying drawing 2B-B electronic lighter, between requiring up and down enough gaps are arranged, in order to avoid electrion.Push away (or pressing down) electronic lighter switch before weldering, the place ahead, burning torch handle left side are dug a square hole, installed one, see accompanying drawing 1 1., electronic lighter one end is connected with weldering, burning torch body, and the other end is seen accompanying drawing 2 by high-voltage line.3. B-B draws along the handle front end.Battery

Be installed in the handle rear, by lead Joining with electronic lighter, in a word, is that next electronic lighter can be installed to the requirement of handle, and reliably working effectively.

3, the installation of shower nozzle, electronic striking head: shower nozzle is 6. 2. as close as possible under the situation that does not influence electrion with the electronic striking head, sprinkler configuration and arc welding gun head structure are similar, cut open 6. 5. as accompanying drawing 2, C-C, consider weight, minification as far as possible, shower nozzle is connected with mixture pipe with screw thread, and the place ahead installs a sparking plate additional With ignition pin

Cooperate and get angry ignition pin With the sparking plate

Should not influence the as close as possible of gaseous mixture ejection, ignition pin and shower nozzle mouth distance should be less than the distances between ignition pin and the sparking plate.

4, fixed mount, as accompanying

drawing

1,7. use the spring steel plate manufacturing, with bolt the folder form is fixed on weldering, the burning torch pipe, requirement can be with its high-voltage line, rotor, mixture pipe, shower nozzle, secure fixation is lived, preceding fixed mount and ignition pin should leave certain distance.

Claims

1, a kind of weldering, burning torch of lighting a fire automatically with electronics, it is characterized in that: in weldering, burning torch handle, electronic lighter (1) is housed, along its handle front end and weldering, burning torch head high-voltage line (3) is arranged, rotor (2) reaches below weldering, burning torch gaseous mixture switch (4) is housed, along its below to front end mixture pipe (5) is arranged, nozzle head (6) is fixed on weldering, the burning torch with fixed mount (7) respectively.
