Technical Field

[0001] This utility model relates to the technical field of strip steel processing equipment, specifically to an automatic distance measuring and forming device for crescent laser cutting of strip steel weld seams. Background Technology

[0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of different industrial sectors for the industrialized production of various metal or mechanical products. It has excellent ductility and plasticity and is often used to manufacture products such as steel pipes and cold-rolled strip steel.

[0003] Laser crescent cutting is an essential auxiliary device in high-precision specialized equipment designed for steel strip splicing, cutting, and sheet metal processing. After steel coils are spliced ​​and welded, misalignment may cause stepped protrusions at the interface between the two steel strips. If this is allowed to proceed directly to subsequent rolling or coiling processes, it can easily lead to strip breakage or damage to the conveyor rollers. Laser cutting equipment shears the metal on both sides of the weld, creating a crescent-shaped notch, ensuring a smooth transition at the interface and reducing the risk of strip breakage.
