Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a flux-cored welding wire unwinding device. Background Art

[0002] In welding operations, it is essential to use flux-cored wire. In order to prevent the flux-cored wire from getting damp and affecting the welding quality, the flux-cored wire is generally placed in a wire barrel. When using it, just open the end cover of the wire barrel. In actual use, the welding wire and the wire barrel often get stuck, or the welding wire is too loose and contacts the machine tool to cause sparks, which will greatly reduce the processing efficiency. At the same time, if the wire barrel is open, it is easy for foreign matter to mix in, the welding wire to rust, and ash to fall, thereby affecting the welding quality. Especially when performing online surfacing operations, the working site environment is complex and the downtime and maintenance time is tight. If there is a problem with the wire feeding, it will lead to a decrease in processing efficiency, affect the overall production plan, and cause economic losses. Therefore, during the welding operation, a flux-cored wire release device that can solve the above problems is needed. Utility Model Content

[0008] The utility model has the following advantages:

[0009] The welding wire unwinding device of the utility model is provided with a welding wire barrel cover at the upper end of the welding wire barrel. The welding wire bracket is adjusted to a suitable angle and fixed by tightening knobs on both sides of the welding wire barrel cover. The welding wire comes out through the wire outlet of the welding wire barrel cover and goes out through the wire outlet of the bracket to realize the wire unwinding process. The angle of the welding wire bracket is adjustable and can be applied to welding operations in various environments. The wire comes out smoothly without jamming. After the wire comes out, there will be no sparking phenomenon after the welding wire touches the conductor. The welding wire barrel cover can prevent foreign matter, dust, liquid, etc. from entering the welding wire barrel to contaminate the welding wire, especially in a humid environment, and can play a moisture-proof role for the remaining welding wire after opening.
