Automatic electrowelding electrode feeder

Abstract

The invention provides an automatic electrowelding electrode feeder comprising a connecting rack, a feed box, and a power unit. The automatic electrowelding electrode feeder is fitted on a welding torch employing welding wires for welding. The feed box and the power unit are fitted to the end of the welding torch through the connecting rack. A welding wire for welding is passed into the feed box; a transmission structure is arranged in the feed box; the power unit drives the welding wire to move forward. The forward direction of the welding wire and a hot jet flow direction of the welding torch intersect at one point. Speed of feeding the welding wires in the welding manner is evener, welding quality can be improved effectively, a welder can operate with one hand using the automatic electrowelding electrode feeder, welding is more convenient, and the automatic electrowelding electrode feeder can be freely used in more complex environments.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to an automatic electric welding strip extension device. Background technique [0002] Electric welding is a common name for arc welding. It is a welding operation that uses welding rods to melt the places where metal parts need to be connected through arc high temperature. Because the flexibility of welding parts is often required, most of the non-standard parts are usually welded by hand. There are many types and methods of welding. Among them, in welding methods such as MIGA welding, brazing, and gas welding, it is necessary to hold the welding wire in one hand and the torch in the other hand, so that the operation of two hands is not necessary during welding. If the welding wire cannot be fed in time, it will cause missing welding, so that the product has a welding hidden danger that is not strong enough, and if the welding wire is fed too much, it will affect the appear...

Problems solved by technology

There are many types and methods of welding. Among them, in welding methods such as MIGA welding, brazing, and gas welding, it is necessary to hold the welding wire in one hand and the torch in the other hand, so that the operation of two hands is not necessary during welding. If the welding wire cannot be fed in time, it will cause missing welding, so that the product has a welding hidden danger that is not strong enough, and if the welding wire is fed too much, it will affect the appearance of the welding place, and at the same time cause some parts that require precision The size of the weld is not accurate enough

Moreover, this kind of welding requires two hands to operate and coordinate the operation. In some welding positions, it is not convenient, especially when welding in some smaller holes, it is difficult for the welder to use both hands to operate inside.
