Abstract

This invention relates to a rolling and resistance welding device and its control method for inlaying spirals, belonging to the technical field of spiral processing equipment for metal strips. It includes a frame and a spiral forming mechanism mounted thereon. The spiral forming mechanism includes an operating platform with resistance seam welding components and corresponding spiral inlay rolling components. The rolling components form a constrained cavity through left and right side molds and a lower mold. A servo motor drives the rolling mandrel to rotate, completing the rolling process, while a dual-axis telescopic cylinder drives the mandrel forward and backward. The seam welding components use a telescopic motor and a lifting cylinder to drive a voltage wheel for two-dimensional trajectory adjustment and continuous welding. A pallet conveyor and a material handling robotic arm are also provided on the side of the equipment. Integrating the rolling and resistance seam welding processes into the same station eliminates deformation and positional deviations caused by secondary clamping of elastic workpieces, achieving integrated production from automatic feeding and rolling to precision seam welding, significantly improving the weld quality and production efficiency of the spirals.
