The position of the workshop on the general plan should be arranged in the downwind position of the local perennial wind direction, and away from the precision equipment and modeling department that require vibration prevention. The design of the factory building should be reasonable to minimize the impact of noise and vibration on the surrounding environment. Corresponding noise reduction measures are taken for different noise sources, and closed operations should be implemented when conditions permit. Replacing forging with low-noise and non-impact processes instead of high-noise and impact processes. Extrusion, press die forging, and rotary machining should be used instead of on-hammer forging. Forging equipment with good rigidity, low noise, low vibration and hydraulic transmission should be used.
Do not use or use forging hammers as much as possible. When selecting forging hammer equipment, you must take measures to reduce vibration, prevent vibration, and isolate vibration (spring foundation, adding dampers, rubber cushions, and installing anti-vibration grooves). Forgings that have reached a certain economic volume, a forging production line should be organized to reduce the number of semi-finished product stacking accesses and reduce the number of collisions between forgings. For small and medium-sized forgings, various low-noise transmission devices should be used. Avoid high drop roll during transportation.
Acoustic and optical signals are used to connect the hydraulic press with the high-pressure pumping station. For larger pumping stations that supply multiple hydraulic presses, a separate factory building should be established, and sound absorption measures should be taken to reduce noise, suspend sound spaces in the space, and install sound insulation barriers. Perform sound insulation. When cutting with a bar shearing machine, the shearing process and tooling should be improved to reduce shearing noise. The exhaust hole of the pneumatic pressing device on the automatic feeding system shall adopt a damping or impedance composite muffler.
