冲裁液压机缓冲系统

Buffer System in Hydraulic Punching Press

为实现液压机在冲裁过程中的减振和降噪,提出一种可以广泛应用于冲裁液压机的缓冲系统。在对缓冲机理进行分析的基础上,建立液压缓冲系统的综合特性模型及缓冲过程的动态模型,运用Matlab软件仿真技术进行计算分析,阐明缓冲作用工作点、节流阻尼、缓冲油缸作用面积和缓冲腔容积大小与缓冲效果间的关系。结果表明:该结构设计具有一定的创新性和实用性,可为同类产品设计提供借鉴。

A kind of hydraulic punching press that is widely used in the buffer system is researched to realize the vibration and noise reduction in hydraulic punching process, and a comprehensive system of hydraulic characteristics of the buffer model and dynamic model of the buffer process is established based on the buffer mechanism analysis, using the Matlab software to calculate and analyze clarifies the role of the buffer working point, throttling damping, working area of the buffer cylinder and the relationship between the buffer cavity volume and the effects of buffer. The structure of buffer system is reasonable, innovative and practical and can be referred by the same kind of product.
