Abstract
The utility model relates to a special igniter of a common welding-cutting torch widely used in industrial and mining enterprises, which is an auxiliary tool in the welding working. The special igniter can provide timely igniting process for the welder and eliminate the trouble of carrying a lighter, thereby being rapid and safe. The unique design enables the special igniter to adapt to reform all the existing common welding-cutting torches. The special igniter of the welding-cutting torch is fixed at the front end of a welding-cutting nozzle, and adopts a spring reset structure; when igniting, the igniting electrode is pushed to the best position at a gun nozzle head, and then the fire ignition is made; after the ignition, the hand is relaxed, and the igniter returns to the original position by the action of the spring. The special igniter has the beneficial effects that 1, when igniting, the hand position is far from the gun nozzle, the hand cannot be burnt, and the safety is increased; 2, after igniting, the igniting electrode returns to the original position, preventing the high temperature fire from burning down the igniter; 3, evading the lower section of the gun nozzle makes convenient for the operation using a circle-cutting compass and a liner; 4, the cost is low, being suitable for the reform of prior China-made tools.
Description
Affiliated technical field
The utility model relates in a kind of industrial and mining enterprises and generally to use, common welding torch dedicated points firearm is the aid in the welding job.It can save the trouble of carrying lighter for the welder provides ignition procedure timely, not only fast but also safety.Original design adapts to it and transforms existing homemade common welding torch.
Background technology
In modern enterprise, the cutting of metal structure and welding are except adopting arc welding, and argon arc welding is outside the vanguard technologies such as plasma cutting.Now generally still adopting traditional gas welding, Methods of OFC-A.It has easy and simple to handle, and flexibly, adaptable advantage is fit to vast medium-sized and small enterprises and uses in engineering with in producing.
The instrument that gas welding is used is except oxygen cylinder, and beyond acetylene cylinder and the pressure reducer, topmost has been exactly welding torch and cutting torch.What generally use on producing now is a kind of jet absorption type welding torch.The first step of use is lighted a fire exactly, during igniting, must be noted that safety, will burn hand unless you give your whole attention to it, damages to the workman.To this problem; The people is all arranged in research both at home and abroad, now, a kind of welding cut bit of automatic igniting occurs in Japan, and domestic also someone succeeds in developing, but because of its mechanism's complexity, cost is higher, is extensively promoted always.
Summary of the invention
In order to solve the practical problem in the above-mentioned production, I look for another way, and propose a new technology solution.It is based on such phenomenon, when the welder in ignition process, even lighter does not go out naked light sometimes, still, electric spark fragmentarily also can be lighted welding torch.This phenomenon of a tree name, I have designed a kind of common welding torch dedicated points firearm.It is characterized in that; Be fixed on the igniter of welding mouth front end, adopt a kind of spring reset structure.When igniting,, be advanced to rifle mouth optimum position earlier with ignitor, percussion igniting then, after lighting, openhanded opening, under spring action, igniter returns initial position.
Useful effect is; Hand position is far away from the rifle mouth during igniting, can not burn hand, increases security.Igniting back ignitor returns initial position, prevents that the high temperature fire burns from ruining igniter.Dodge shooting mouth hypomere, give and use cyclotomy rule and liner operation, it is convenient to create.With low cost, be fit to existing homemade instrument transformation.
Description of drawings
Now in conjunction with an embodiment; Common welding torch dedicated points firearm is described in detail its structure.
Accompanying drawing 2; Common welding torch dedicated points firearm internal view
Accompanying drawing 3; Common dedicated points firearm welding torch 3 d effect graph
Wherein, Igniter main body (1), igniter pushing button (2), last position block (3), rifle body fixed mount (4), bolt (5), piezoelectric crystal component (6), high-field electrode (7), negative pole (8), following positioning baffle (9), spring (10), welding torch (11).
The specific embodiment
Bolt (5), locking rifle body fixed mount (4) installs in the inner slide, igniter (1), button (2), piezoelectric crystal component (6), high-field electrode (7), and negative pole (8) is gone up locating piece (3), following positioning baffle (9), and igniter back-moving spring (10).
All member all adopts the thermosetting plastics injection molded, and is with low cost, safe and reliable.Accompanying drawing 3; It is the 3 d effect graph of common welding torch (11) device dedicated points firearm.
When needing igniting, open the acetylene valve earlier, touch the button with hand, igniter can move along slideway, when arriving assigned address.Last locating piece blocks, and the compressing piezoelectric crystal component that continues to touch the button produces high voltage direct current, makes high-field electrode and negative pole point discharge, produces electric spark, lights the welding torch.After loosing one's grip, under the effect of spring, the rapid reposition of igniter, ignition process finishes.
Claims (2)
1. a common welding torch dedicated points firearm of being made up of rifle body fixed mount and igniter main body is characterized in that; Igniter adopts a kind of spring reset structure, is attached on the common welding torch.
2. according to a kind of common welding torch dedicated points firearm of claim 1, it is characterized in that; Rifle body fixed mount (4) by bolt (5) locking is enclosed within welding torch cutting torch top, be equipped with in the fixed mount slidably, by: the igniter (1) that button (2) piezoelectric crystal component (6) positive electrode (7) negative pole (8) constitutes, the configuration of fixed mount two ends are gone up locating piece (3) positioning baffle (9) and and the supporting back-moving spring (10) of button down.
