Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a torch cable in a welding device having a torch at a tip.

[0002]

[Prior art]

 In a torch cable of a welding device having a torch at a tip, a wire is arranged in a core tube and a shield gas is conveyed, and a gap is formed between the core tube and the jacket tube. A torch cable for a torch through which an arc welding wire and a control wire are penetrated is well known, for example, as disclosed in Japanese Utility Model Publication No. 4-21657.

In general, in the torch, a device for supplying air for blowing off a sputter attached to the inner peripheral surface of the torch nozzle and a device for supplying assist gas around a shield gas are provided. Some are equipped with peripheral devices such as a cooling water or high-pressure air supply device for cooling around the torch and the torch nozzle, and an air motor for weaving the automatic torch.

Meanwhile, a fluid conduit for supplying a fluid for the peripheral device provided with the peripheral device is formed independently of the toe cable and guided to the peripheral device.

[0005]

[Problems to be solved by the invention]

 When the fluid conduit for the peripheral device is formed separately from the toe cable as described above, the fluid conduit and the toe cable are entangled with each other when the torch is moved, so that there is no problem. There is a risk of coming. In addition, since the fluid conduit and the toe cable move independently of each other, there is a possibility that each of the fluid conduit and the toe cable obstructs a surrounding person.

[0006] The present invention has been made in view of such problems of the prior art, and the purpose is to combine a fluid conduit and a toe cable. Therefore, it is an object of the present invention to provide a safe torch cable that prevents mutual entanglement and does not interfere with the welding operation.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the torch cable of the present invention is characterized in that a fluid conduit for peripheral equipment is additionally penetrated between the core tube and the jacket tube. It is a sign.

[0008]

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a torch connected to one end of the torch cable 2 via a connection pipe 3, and to the other end of the torch cable 2 via a wire introduction guide 4. Introduced wire 5, shield gas 7 supplied from shield gas supply pipe 6, arc welding electric wire 9 connected to welding power supply side 8, control connected to control power supply side 10, 10 ' Electric wires 11, 11 'and an inlet pipe 12 for introducing a fluid to peripheral equipment are input.

FIG. 2 shows a cross-sectional view of the toe cable 2 which passes through the toe cable 2 in a core tube 13 at the center thereof. Arc welding wire 9 and control wires 11, which penetrate the torch cable 2 between the core wire 13, the shield gas 7, and the core tube 13 and the jacket tube 14. And a fluid conduit 15 for peripheral equipment.

A wire 5 supplied from the torch cable 2 to the torch 1 through the connection pipe 3 passes through the center of the torch 1 and serves as a consumable electrode at the tip of the torch 1. The used shield gas 7 is blown out from the diffuser 16 into the nozzle 17 to form a shield atmosphere for welding with the wire 5.

The electric wire 9 for arc welding is also guided to the torch 1 and is used to carry the welding current. However, the control electric wires 11 and 11 ′ are mainly composed of a torch cable as shown in FIG. A lead line 18 is used to control peripheral devices (not shown) such as an automatic torch from one end of the handle 2.

The fluid conveyed through the fluid conduit 15 in the torch cable 2 is, for example, high-pressure air when it is for blowing off spatters attached to the inner peripheral surface of the nozzle. When the gas is supplied to the vicinity of the shield gas at the time, the gas is the gaseous assist gas. In these cases, the gas is sent to the torch 1 via the connection pipe 3. The fluid conveyed by the fluid conduit 15 in the torch cable 2 is, for example, cooling water or high-pressure air for cooling the periphery of the nozzle 17, and furthermore, the fluid of the torch 1 For driving the air motor for the wing, it is high pressure air, etc. In these cases, as shown in FIG. 19 to a desired peripheral device (not shown).

The fluid conveyed through the fluid conduit 15 is selected depending on the purpose of use of the peripheral device. If the peripheral device has a supply / discharge function, two fluid conduits 15 will be used, and a plurality of fluid conduits 15 corresponding to the number must be used to introduce fluid to a plurality of peripheral devices. And

Since the torch cable 2 for the torch described above is used, the fluid conduit 15 for the peripheral device is built in the torch cable 2, so that the fluid conduit as in the prior art is used. The torch cable and the torch cable are not entangled with each other, such as when the torch moves, and there is no risk that the fluid conduit and the torch cable move independently of each other. Therefore, there is no possibility that each of the fluid conduit and the toe cable is in the way.

[0015]

[Effect of the invention]

 According to this invention, a fluid conduit for peripheral devices was additionally penetrated between the core tube and the jacket tube in the toe cable, so that the toe cable could become entangled during welding work. It is a safe torch cable for a torch, because the cable does not hinder the surrounding people as well as the surrounding people.
