The invention discloses a stacked combined type heavy hammer sheet and a manufacturing method thereof and belongs to the technical field of hammer manufacturing. The heavy hammer sheet comprises heavyhammer sheet bodies, wherein a square groove is formed in an upper surface of each heavy hammer sheet body, a connecting rod mounting groove is formed in the middle of each heavy hammer sheet body, the multiple heavy hammer sheet bodies are arranged in an overlapped mode, butt joint pieces are symmetrically mounted on two sides of the connecting rod mounting groove in the middle of each heavy hammer sheet body, and the butt joint pieces are symmetrically distributed with the circle center point of each heavy hammer sheet body as the center. The stacked combined type heavy hammer sheet is advantaged in that the whole combined heavy hammer sheet is integrated into a whole, overall stability is improved, after the heavy hammer sheets are combined, the combined heavy hammer sheets are arranged on the cable, the heavy hammer sheet is convenient to assemble and disassemble, high in bonding strength, high in use stability and high in practicability, shock resistance is improved, use safety is improved, compactness and waterproof performance of a coating can be effectively improved, connecting friction force is increased when the square connecting rod mounting groove polished by a file ismounted, and mounting stability is improved.
