The invention discloses a steel plate spring vulcanization noise reduction device. The steel plate spring vulcanization noise reduction device is characterized in that a Q235 base plate is arranged on the upper surface of one end of a reed, a PU gasket is vulcanized to the upper surface of the Q235 base plate, and a leaf spring clamp is arranged at the lower portion of the reed; and the leaf spring clamp, the reed, the Q235 base plate and the PU gasket are riveted together through rivets. By means of the above arrangement, the leaf spring clamp, the reed, the Q235 base plate and the PU gasket are riveted together, the firmness of connection of the Q235 base plate, the PU gasket and the reed is improved through the rivets, and the aim of noise reduction of the reed is achieved through the Q235 base plate and the PU gasket.
