前言由于在造型的两个重要工序——填砂和压实中增加微震击,可以使填砂均匀、改进紧实度的不均匀现象,增大压实效果(即能在相同的压实比压下获得较高的紧实度),所以气动微震造型机获得广泛的应用。对于震击机构的性能分析及合理设计也理所当然地引起人们的注意。气动微震造型机的震击机构就其本质来说,是一个将压缩空气能转化为机械冲击能的换能机构,因此,对震击机构性能的研究及其合理设计就不能脱离开表征震击机构的换能过程的示功图的讨论。可以说震击机构的一切参数选择的最基本的出发点,都是建立在示功图的分析上的,这却正是目前普遍存在的不足之处。本文的目的 Preface Due to the two important processes in modeling - micro-shock in sand filling and compaction, sand filling can be uniform, improve the unevenness of compaction, increase the compaction effect (ie, the same compaction ratio Pressed to obtain a higher degree of compaction), so pneumatic microseismic modeling machine has been widely used. It is a matter of course that people pay attention to the performance analysis and rational design of the shock mechanism. As a matter of fact, the shock mechanism of a pneumatic microseismic molding machine is a transduction mechanism that can convert compressed air into mechanical impact energy. Therefore, the research on the performance of a shock mechanism and its reasonable design can not be separated from the characterization of shock Discussion of the mechanism diagram of the transduction process. It can be said that the most basic starting point for selecting all the parameters of the striking mechanism is based on the analysis of the dynamometer, which is the ubiquitous deficiency at present.
