The invention relates to a manufacturing device of an electric smelting assembly sample. The manufacturing device comprises a machine frame, a moving mechanism, a cutting mechanism and a clamping mechanism. The manufacturing device is characterized in that an electric smelting assembly is abutted against a first positioning piece, a pressing strip is arranged on one side, opposite to the first positioning piece, of the electric smelting assembly in a pressing mode, a first power source drives a rotating shaft to rotate, the rotating shaft drives a first saw blade and a second saw blade to rotate, the cutting mechanism or the clamping mechanism is arranged on a sliding plate, the sliding plate is arranged on the machine frame and can move relative to the machine frame so that the cutting mechanism and the clamping mechanism can move relative to each other, the width of the pressing strip and the width of the first positioning piece both are smaller than the distance between the first saw blade and the second saw blade, and the first saw blade and the second saw blade can simultaneously cut the electric smelting assembly, so that the electric smelting assembly sample with a certain width is obtained. According to the manufacturing device for the electric smelting assembly sample, the manufacturing process of the electric smelting assembly sample is simpler, and the situations that the difficulty and the complexity of machining are increased due to machining multiple times are avoided.
