Description

Portable welding device capable of automatic transfer {AUTOMATIC TRANSFERABLE PORTABLE WELDING APPARATUS}

The present invention relates to a portable welding device capable of automatic transfer, and more particularly, to improve the welding torch by improving the application No. 10-2008-0032897 "Automatic transferable portable welding apparatus" filed by the inventor. The present invention relates to a portable welding device capable of automatic transfer for moving in the rearward and upward and downward directions.

In general, various structures are installed during ship construction, and the work of combining a number of reinforcing beams, such as H-beams, to a certain length for the reinforcement of the hull, is performed. In addition, the structure and the structure reinforcement beams are installed in the hull, the majority is made through a welding operation.

Therefore, a number of welding operations, which are usually performed during ship construction, are performed while moving along a beam of a constant length installed as a structure.

Republic of Korea Utility Model Publication No. 20-0169936 "Vertical automatic welding device" has a magnet attached to the lower edge of the rail, the carriage body is installed on the rail, the torch separation fixture is attached to the left side of the carriage body, Torch left and right adjustment box is connected to the torch separation fixture, and the torch up and down adjustment box is connected to the torch left and right adjustment box by the torch left and right adjustment support, and the torch up and down adjustment box is connected to the torch up and down adjustment support. Torch up and down support is connected, the torch mount is installed at the tip of the torch up and down support, the torch is fixed to the torch mount, and the torch is connected to the feeder control and toe at the end of the torch up and down support. Torch up and down fine adjustment handle is installed for fine up and down movement of the Och mount, and right and left of the copper shoe on the right side of the carriage body The fixed box is attached, and the copper shoe left and right adjustment box is connected to the copper shoe left and right adjustment box, the copper shoe support is connected to the copper shoe left and right adjustment support, and the copper shoe is installed at the tip of the copper shoe support. It is proposed a vertical automatic welding device which has the effect of reducing and preventing the failure of the control circuit.

Further, Korean Utility Model Publication No. 2000-0005792 "Welding Carriage with Minimized Welding Hold" is a welding carriage in which guide wheels are formed, and a torch fixing holder having fixing screws on both sides of the welding carriage is installed, and a welding torch The present invention proposes a technique of forming a fixed engagement portion fitted to a torch fixing holder in a fixed manner, and fixing the welding torch to the torch fixing holder in the traveling direction of the welding carriage.

As such, a number of welding operations that are usually performed during ship construction are performed while moving along a beam of a constant length, which is installed as a structure. Since there must be a problem that the operator must be observed continuously, and the preparation work, such as the operation of the welding device, the ignition of the welding torch is made separately, there is a problem that the operator must manage separately for each welding device.

On the other hand, Application No. 10-2008-0032897 "automatic transferable portable welding device" that the inventors have filed to drive the driving unit automatically when the ignition of the welding torch to automatically move the welding section, welding section When the end of the welding torch is automatically extinguished, the automatic welding is possible by combining the torch for normal manual work without using a separate automatic welding torch, guiding the welding device Although there is an advantage of not using the rail for the welding, it is possible to adjust the height of the welding torch because the work is performed by setting the upper and lower heights so that the welding is not made precisely at the welding part, and therefore, an apparatus capable of adjusting the upper and lower heights is required. Was done.

Therefore, the present invention has been proposed for such a necessity. When the operator ignites the welding torch, the driving unit is automatically driven to automatically move the welding section, and when the welding section is finished, the extinguishing of the welding torch is automatic. The new type of automatic transfer without the need to use a rail for guiding the welding device, and to enable automatic welding by combining the torch for normal manual work without using a separate automatic welding torch. It is to provide a portable welding apparatus possible.
