Description
Technical Field
[0001] The invention relates to the technical field of pipeline welding equipment, in particular to an anti-corrosion elbow welding assembly device. Background Art
[0002] Anti-corrosion elbows have excellent corrosion resistance, especially in high temperature, high pressure and corrosive media. They are widely used in the petroleum, chemical, electric power and other industries. When using anti-corrosion elbows, welding operations are indispensable. This operation can combine and weld multiple groups of elbows, making it convenient for subsequent use.
[0003] For example, the invention patent disclosed in the publication number CN118404234B is a pipe bending welding device for processing metal products, comprising a base plate, a slide fixedly provided at the center of the top surface of the base plate, and a slide frame slidably fitted on the top of the slide. The present invention adjusts the two rotating frames to a parallel state by the ring size, and the inner ends of the two pipe bends fit together. The welding head of the welding gun is used to weld the connection points of the two pipe bends accordingly. After loosening the second nut, a plurality of balls rotate synchronously inside the partition groove using the ring, and the balls slide inside the partition groove using the second support rod, and the second support rod is matched with the partition groove to ensure the rotation stability of the rotating structure in the horizontal direction. The balls use the first support rod and the rotating sleeve to limit the annular clamp, and the annular clamp is used to drive the pipe bend to rotate synchronously. At this time, the rotating structure drives the pipe bend to rotate, which facilitates the welding head of the welding gun to perform comprehensive welding processing on the fitting points of the two pipe bends, thereby reducing the labor intensity of the welder and improving the work efficiency of pipe bend welding.
[0004] Although the above-mentioned equipment can perform welding operations on bent pipes, it can only perform welding operations on specific bent pipes, which makes the above-mentioned equipment insufficient in adaptability to welding special-shaped bent pipes. At the same time, the above-mentioned equipment also has insufficient accuracy in guiding and positioning when welding bent pipes. Therefore, an anti-corrosion bent pipe welding assembly device is needed to solve the above-mentioned problems. Summary of the Invention
