Install the sound insulation cover: Enclose the high-speed press transmission system and cover shell, which can significantly reduce the noise of the transmission parts. For motors with large power and high noise, a partial sound insulation cover or a closed sound insulation cover should also be provided. Outside the working area of the high-speed punch, installing a movable protective grille or sound insulation cover can make the noise reduction effect of the high-speed punch more significant.
2. Installation of sound insulation room: The wall of the sound insulation room of the punch press adopts a special sound insulation material structure, which can effectively prevent the noise from scattering outward.
3. Change the mold structure: the punching noise is proportional to the punching force. By changing the structure of the die, the punching force can be reduced and the action time of the punching force can be prolonged, that is, the oblique cutting edge is used. Step punch and heated blanking method to reduce stamping noise.
