Description

Carbon dioxide gas automatic welding system

The present invention relates to an automatic welding device for carbon dioxide gas, and more particularly, it is possible to proceed in the up, down direction or left, right direction by the control of the control unit while moving the base material to be welded in the direction of rotation or immediately before. The present invention relates to an automatic welding device for carbon dioxide gas, which allows automatic welding with carbon dioxide (CO ₂ ) using a welding torch.

Typically, the welding gas container or power supply and the main feeder is fixed in a fixed place due to the weight or size.

Therefore, when the position or the material of the welding operation is close to them, the welding torch is immediately bound to the main feeder to receive the welding wire.

On the contrary, when the position or material of the welding work is far from them, a separate extension cable is connected between the main feeder and the welding torch to forcibly transfer and supply the welding wire wound on the main feeder to the welding torch. Will let you.

As such, a conventional apparatus for transferring and supplying a welding wire to a welding torch is already known. This is a structure in which the welding wire is pressurized using a set of feed rollers only in the main feeding device, so that the transmission driving force is small and the welding wire is used. As it pushes from the back, the friction of the welding wire is generated in the passage of the extension cable, and the bending force of the welding wire is increased by this frictional force, which causes the slip rate in the feed roller to increase, resulting in a loss of power and a lot of force in conveying. This will expose the closed end of the transfer efficiency is greatly reduced.

In view of this, there is known a structure in which an auxiliary feeder is provided at the end of the connecting cable, but it is configured to have a drive source (driving motor) completely independent from the main feeder, and such a structure includes the main feeder and the auxiliary feeder. Since each drive motor is provided in the device, there is an uneconomical problem that leads to an increase in power consumption, and because the structure is complicated and the weight is large, the productivity is inconvenient and the handling is inconvenient, and a separate drive motor is used. It is very difficult to accurately match the rotational speed between the feed roller and the feed roller of the auxiliary feed device, which causes slip between the feed roller and the welding wire, resulting in a loss of power and a decrease in the transfer efficiency.

In order to solve the above problems, a welding wire transfer apparatus of a carbon dioxide gas welding machine has been recently published in Patent Application No. 10-1996-0059461.

Looking at the welding wire feeder of the conventional general carbon dioxide gas welder, the first grooved feed roller is formed in the guide groove of the annular welding wire is formed around the body and is connected to the motor and rotated, and the pressure can be adjusted arbitrarily A first feed device including a driven feed roller to pressurize the welding wire to impart a feed friction force, a main feeding device including a winding bobbin of the welding wire, and a guide groove of the welding wire formed around the trunk And a two-drive feed roller and a driven feed roller installed above the second-drive feed roller in a state in which the pressing force is controlled to pressurize the welding wire to impart a feeding friction force, wherein one side is bound to the main feed device. In a known structure comprising a subsidiary feeder that is selectively engaged with the other side of the cable, the main feeder of the Bevel gears integrally formed on one side of the first driving feed roller and the second driving feed roller of the auxiliary feeder, and an electric bevel rotatably arranged in the main feeder and the auxiliary feeder in engagement with the bevel gears. It is installed in the longitudinal direction on the gear and the surface of the extension cable, it is detachably coupled to the connecting hole of the electric bevel gear by using a connector formed at both ends, and the driving force of the first driving feed roller is connected to the second driving feed roller. Consists of a flexible drive shaft for power transmission.

However, the welding wire transfer apparatus of the conventional general carbon dioxide gas welder made as described above has a problem in that the speed of the welding operation is inevitably decreased since the operator directly grips the welding land to perform welding on the base material.

In addition, the welding wire transfer apparatus of the conventional general carbon dioxide gas welder made as described above, because the operator grips the welding land directly and welds to the base metal, as described above, the precision is low and the defect rate of the product is inevitably generated. There was a problem.
