The invention provides a sectional material multi-axis cutting device comprising a lifting mechanism and a cutting mechanism. The lifting mechanism comprises a base and a movable frame, and a pair offork-shearing type lifting frames is hinged between the movable frame and the base. First movable plates slidably arranged on the surface of the base are hinged to the front sides of the lower ends ofthe two lifting frames, and transmission assemblies capable of driving the movable frame to vertically rise and fall are connected to the first movable plates. The cutting mechanism comprises a sliding assembly and a cutting assembly, the cutting assembly comprises a pair of L-shaped vertical plates which are arranged on the surface of the movable plates in the backward direction, and a cutting blade which is in transmission connection with a cutting motor is arranged between the vertical plates. According to the sectional material multi-axis cutting device, the requirement for machining sectional materials of large specifications can be met, adjustment can be conducted at any time according to the machining requirement so as to achieve the optimum machining angle, the purposes that the machining quality is good, operation is easy, the production efficiency is high, and the labor intensity of workers is low are achieved, and the sectional material multi-axis cutting device can be widely suitable for machining of the various sectional materials.
