Application range of noise reduction in sound insulation room of punch equipment
Design of sound insulation room for large and medium-sized high-speed automatic punch, punch shock absorber punch is the most important and necessary machine and equipment in plate processing industry. When the punch is working, it will cause mechanical transmission noise. To solve the problem of punch noise, we can use the technical treatment countermeasures of punch sound insulation room, automatic punch, small and medium-sized punch sound insulation box, punch static sound, punch silencing room and punch sound insulation room.
The sound insulation room of punch press has simple technical measures and good noise reduction effect. It is widely used in noise control engineering. The sound absorption of materials focuses on the reflected sound energy on one side of the sound source, and the goal is to reduce the reflected sound energy; Sound insulation materials focus on the scattered sound energy on the other side of the outgoing sound source, and the goal is to reduce the scattered sound energy. The difference between sound-absorbing materials and sound-insulating materials is that sound-absorbing materials have little reflection on outgoing sound energy, which means that sound energy is easy to enter and pass through such materials; It can be imagined that the material of this kind of material should be porous, loose and breathable, which is a typical porous sound-absorbing material.
The structural type of sound insulation room is: there are many interconnected micropores from the surface to the inside in the material, that is, it has certain air permeability. For sound insulation materials, to weaken the scattered sound energy and block the propagation of sound, they can not be as porous, loose and breathable as sound-absorbing materials. On the contrary, their materials should be heavy and dense, such as steel plate, lead plate, wall and other materials.
