Description

Technical Field

[0001] This utility model belongs to the field of strip steel splicing, and in particular relates to a steel plate cutting and welding device. Background Technology

[0002] Steel strip is a narrow and long steel plate produced by various steel rolling mills to meet the needs of different industrial sectors for the industrialized production of various metal or mechanical products. Also known as steel strip, steel strip has a width of up to 1300mm, with the length varying slightly depending on the size of each coil. Steel strip can be manufactured from various steel grades, including plain carbon steel, carbon structural steel, spring steel, tool steel, and stainless steel. It is widely used in the manufacture of welded pipes, clamps, washers, spring sheets, saw blades, and cutting blades.

[0003] When spiral-rolled or straight-seam-rolled welded steel pipes are produced from strip steel, the strip steel needs to be continuously fed into the rolling machine. After being rolled and welded into pipes, the pipes are cut to the rated length. The length of each strip steel roll is limited. In order to achieve continuous production of strip steel rolls, the tail end of the first roll of strip steel needs to be connected to the head end of the next roll of strip steel. Currently, this is usually done manually, which makes the welding quality and efficiency uncontrollable and poses production safety hazards. Summary of the Invention
