Grooving device for metal material

The utility model relates to the technical field of machining, in particular to a grooving device for metal materials. The driving part drives the rotating shaft and the blade parts on the rotating shaft to rotate, meanwhile, the moving mechanism drives the rotating blades in the rotating state to move in the space along a slotted product, multi-groove machining of the slotted product on the positioning table top is completed, and the spacing parts are arranged between the adjacent blade parts. The distance between every two adjacent rotating blades is controlled in the mode that the interval parts are stacked, free change of the grooving distance is achieved, the grooving device can be compatible with the blades with different thicknesses, and meanwhile various blades can be replaced. The two ends of the rotating shaft are arranged on the rotating frame, the rotating shaft and the singing are supported, the opposite force generated by grooving is shared, and the cutting face can be smoother. 本实用新型涉及机加工技术领域，涉
