机械压力机是冲压车间的主要加工设备,它产生的冲裁噪声是冲压车间中最强的噪声源。机械压力机也是锻压机械中产量最大、应用最广的设备。因此,研究降低压力机的噪声,对于降低冲压车间的强烈噪声,减轻对周围环境的危害有重要意义。本成果分为两部分。第一部分是降低压力机的运转噪声。研制陶瓷多孔消声器,降低摩擦离合器 Mechanical press is the main processing equipment in the press shop, it produces punching noise is the strongest noise source in the press shop. Mechanical presses is also the largest forging machinery, the most widely used equipment. Therefore, research to reduce the noise of the press is very important for reducing the strong noise in the press shop and reducing the harm to the surrounding environment. The result is divided into two parts. The first part is to reduce the operating noise of the press. Development of porous ceramic muffler to reduce friction clutch
