Description
The present invention relates to a head assembly for a welding torch which can be applied to both CO 2 arc welding, TIG arc welding and passive metal arc welding, and an integrated welding torch using the same.
Arc welding is the most widely used joining method currently used for joining metal materials by fusing welding using an arc as a heat source.
Generally, arc welding can be classified into carbon arc welding using carbon electrode and metal arc welding using metal electrode depending on the type of electrode used, and different types of welding can be performed depending on the respective welding method, cooling method, A welding operation is performed using a torch.
In particular, carbon arc welding is a method in which an arc is generated between a welding base material and a carbon electrode to melt an electrode. Metal arc welding generates an arc between electrodes made of the same kind of metal as the welding base material, Thereby bonding the base material. Accordingly, in the metal arc welding, since the continuous supply of the electrode consumed in the welding torch is required, the electrode portion having a shape different from that of the welding torch for the carbon arc welding is obtained.
Also, in case of welding method, Shield Metal Arc Welding (SMAW), which is most widely used at present, is used in the category of GMAW (Gas Metal Arc Welding) And is classified into CO 2 , MIG, MAG, and Ar welding depending on the type of gas.
In addition, FCAW (Flux Cored Arc Welding) has a working principle such as GMAW, but it uses a self-protection method in which the flux is filled in the wire, And the welding torch having a structure different from that of the GMAW method is used.
That is, in the prior art, each welding torch corresponding to each welding method is used, and a water-cooled type and an air-cooled welding torch are also used separately according to the cooling method.
In addition, the welding torch may be classified into large, medium, and small types according to the length of the torch. In order to perform various welding operations, the user must purchase and use various welding torches according to the welding method, .
On the other hand, Korean Patent No. 10-1412374 entitled " Welding torch and its assembling method " discloses a technique for easily assembling and disassembling a contact tip, which frequently occurs during welding, without a separate tool.
Korean Patent Laid-Open Publication No. 10-2014-0078826 " Welding Torch " discloses a welding torch capable of easily separating a welding tip from a tip holder.
In other words, in the conventional technologies, the welding part is changed only according to the welding method, and the welding part is changed only by the welding method. I can not do it.
It is an object of the present invention to provide an integrated welding torch which can be applied to various welding operations such as carbon arc welding, TIG arc welding and passive metal arc welding.
It is another object of the present invention to provide an integrated welding torch capable of varying a welding direction and a corresponding switching structure according to a variable welding method.
The present invention relates to a cable connector comprising a handle for providing a user's gripping space, a connector body to be fastened to the handle, and a welding cable fastener for fastening a welding cable to the inside of the connector body, A welding torch body provided on one side of the cable connector and including a switching unit for generating a control signal for power control; and a head assembly coupled to the welding torch body, And a head body having a second conduit formed therein for providing at least one exhaust path of gas, wire and electrode at one side of the first conduit, and a second conduit A gas diffuser corresponding to the welding method is mounted on the pipe, and a nozzle, a welding tip and an electrode collector And a fixing unit for adjusting the fixing position of the handle by varying the fastening force of the connector body with respect to the connector body.
According to another aspect of the present invention, there is provided a welding apparatus comprising a handle for providing a user's gripping space, a connector body at least a part of which is inserted into and engaged with the handle, and a welding cable fixing member for fixing a welding cable, And a head assembly provided at one side of the cable connector, wherein the head assembly is provided at one side of the cable connector, And a second conduit for providing at least one of a gas, a wire and an electrode at one side of the first conduit, and a second conduit for providing at least one outlet path of the gas, the wire and the electrode at one side of the first conduit , A gas diffuser corresponding to a welding method is mounted on the second pipe, It mounted jeoptip or more collector electrodes, characterized in that, the fixing means for the handle to adjust the fixed position of the steering wheel to vary the clamping force with the connector body is further provided.
The fixing means is formed in an annular shape cut in at least a part of the handle body surrounding the outer surface of the cable connector and includes a fixing hole and a fixing bolt which is rotationally coupled to the fixing hole, And the fastening force is adjusted.
According to the present invention, the head assembly includes a first conduit and a second conduit communicating with one side of the first conduit, wherein the gas or wire is supplied through the first conduit, and the electrode according to the welding method is selectively mounted on the second conduit .
According to the selected welding method, at least one of a gas diffuser, a nozzle, a welding tip, and an electrode collector is selectively installed in the second pipe so that the user can easily use the welding device for CO 2 welding and TIG welding have.
In addition, in the present invention, by constructing the integrated welding torch by applying the above-described head assembly for welding torch, the electrode according to the welding method, the gas diffuser corresponding to the selected electrode and the nozzle, the shielding means, The welding method can be easily changed.
That is, in the present invention, when the welding operation to be performed is CO 2 welding, a first gas diffuser is mounted on the integrated electrode head body, and a CO 2 welding is performed by mounting a welding tip and a first nozzle on the first gas diffuser .
On the other hand, in the case of TIG welding, a second gas diffuser is mounted to the head assembly, and an electrode collector for fixing a tungsten electrode to an inner space of the second gas diffuser is further provided. The tungsten electrode and the electrode The TIG welding can be performed by mounting the second nozzle to the second gas diffuser accommodating the collector. In the case of manual metal arc welding, a welding operation can be performed by mounting a welding rod to the electrode collector instead of the tungsten electrode and removing the nozzle.
In addition, the head assembly is formed so that the second channel is vertically penetrated, and the opened upper side is shielded by the shielding means, so that the gas leakage can be prevented while easily accommodating the relatively long electrode.
In addition, since the shielding means as described above can be selectively installed in a form that does not accommodate the electrode and accommodates the electrode according to the welding method, the user can easily perform the welding operation by changing the welding method .
Therefore, according to the present invention, at least one of the gas diffuser, the nozzle, the welding tip, and the electrode collector mounted on the head assembly is replaced according to the selected welding method, unlike the conventional welding method in which each welding torch according to the welding method is purchased and used So that it is possible to easily switch the operation, thereby improving the workability and facilitating maintenance and storage.
Further, since the integrated welding torch according to the present invention is capable of moving the handle and changing the direction of the handle according to the necessity such as the welding method and the welding habit of the user, and in addition, the switching means can be operated bidirectionally, It is possible to input a signal and the user can more conveniently perform the welding work.
