Punch is a very popular machine and equipment in our production and manufacturing, but in many cases, there are also some regions that will also raise a bit of distress for you. Noise will appear with the use of punch. Although it is difficult to avoid, we can reduce its basic skills in some effective ways.
Reverberation time refers to the constant sound in the room, the residual sound in the room stops, the vertical plane is digested by the boundary layer everywhere, and the average specific energy is reduced to one millionth of the original. The reverberation time is long, the noise is reflected in the workshop several times, the mechanical energy attenuation coefficient rate is slow, in the same sound source everywhere reverberation time workshop is good at reverberation time, the workshop noise is big.
2. Generally, there are five parts in the sound insulation material. One part of the energy is converted into energy according to the vibration consumption of laminated glass wool and silk, and the other part is extracted from the surface of carbon steel plate. The digestion of vibration can be shared.
3. Because the closure of all production lines is the splicing of small sound-absorbing boards into a closed body, in order to better ensure the actual effect of noise reduction, it is necessary to control the gap in the middle of each sound-absorbing board, generally 1-2. In order to avoid noise as much as possible, sealant can be used to seal the gap.
4. Because of the calorific value caused by the operation of machinery and equipment, coupled with the insulation characteristics of sound-absorbing material glass wool, the temperature is general It is 3-5 ℃ higher than the outside. After the implementation of noise reduction project, in a closed production line, the exhaust fan is generally installed on the top of the sound insulation board to close the air in the indoor space. As a result, the internal negative pressure is caused by the punch press in Henan Province, and the outside gas can enter the internal sound insulation board. Low noise centrifugal fan in the exhaust pipe centrifugal fan selection, in order to avoid the harm of noise effect.
It seems that in order to weaken the destructive power of noise, all fields should cooperate with each other and do it together. In order to improve their basic skills, it is inevitable that we must solve the problem of punching machine better.
