本文研究了一种可广泛用于液压机的冲裁缓冲系统,采用这种缓冲系统,可以有效的阻止冲裁冲击的产生。 对400kN及5000kN液压机进行的大量试验结果表明,应用该缓冲系统可使冲裁噪声下降15dB(A)以上,而冲裁压力只增加3％右左。 应用DSH软件对液压机冲裁缓冲过程进行了仿真研究,结果表明,在冲裁缓冲系统的设计中,缓冲油缸面积及缓冲腔容积的大小对缓冲效果有着决定性的影响 This paper studies a punching buffer system that can be widely used in hydraulic press. With this kind of buffer system, it can effectively prevent the punching impact. A large number of tests on 400kN and 5000kN hydraulic presses show that the damping system can reduce the blanking noise by more than 15dB (A) and increase the blanking pressure by only about 3%. The application of DSH software to simulate the punching buffering process of hydraulic press shows that in the design of punching buffering system, the area of ​​buffer cylinder and the size of buffer chamber have a decisive influence on the buffering effect
