An automatic slag cleaning machine for narrow gap mag/mig welding

Abstract

The invention relates to an automatic slag removal machine with narrow-gap MAG / MIG welding. The automatic slag removal machine comprises a rotary file assembly and a transverse swinging mechanism connected with the rotary file assembly, the transverse swinging mechanism is fixed on an elastic device, and the elastic device is fixed on a height adjusting mechanism; and, a height self-adaptive tracking control system is used for automatically detecting a real-time thickness of each layer of welding seam and outputting the real-time thickness to a height motor of the height adjusting mechanism, and the same thickness of the rotary file can be automatically lifted or reduced after each welding is completed to keep the rotary file and the surface of the welding seam in the same elastic pressingdegree all the time. Therefore, the automatic slag removal machine with the narrow-gap MAG / MIG welding has the advantages that 1, a removal rate of a deoxidation product can reach 100%; 2, impact andvibration do not exist in a cleaning process, and normal work of other automatic welding systems is not interfered; and 3, the production rate of automatic welding construction with narrow / ultra-narrow gap MAG / MIG welding is improved, and the high-strength and low-efficiency manual slag removal is enabled to enter an automatic and intelligent new stage.

Description

technical field [0001] The invention relates to a narrow-gap MAG / MIG welding automatic slag remover capable of automatically removing metallurgical deoxidation products on the surface of a weld bead during narrow-gap and ultra-narrow-gap MAG / MIG welding, and belongs to the field of welding technology. Background technique [0002] Narrow gap welding (Narrow gap welding) technology development began in the early 1960s. After half a century, narrow gap submerged arc welding (Narrow gap SAW) and narrow gap hot wire pulse tungsten arc welding have been developed. (Narrow gap TIG Welding) and narrow gap MAG / MIG welding (Narrow gap MAG / MIG Welding), and have been applied in industrial production. Narrow-gap MAG / MIG welding is significantly superior to narrow-gap submerged arc welding and welding in terms of welding heat input (line energy), space position applicability, mechanical properties of welded joints, simplicity and high efficiency of process technology, welding productivi...

Problems solved by technology

Usually, the time of manual slag removal takes up a large proportion of the welding construction cycle. In order to reduce the labor intensity of workers and improve welding productivity, a needle beam composed of multiple high-strength steel wires is used instead of the hammer head, and a pneumatic reciprocating motion is used to replace the hammer head. The mechanical slag cleaning machine composed of hammer power, auxiliary dragging and height adjustment mechanism has been used in production, but the vibration has an adverse effect on the stability of the welding process, and the cleaning rate cannot reach 100%, which has long been absent. continuous application
