文档介绍：曲轴滚压强化机液压系统的设计
摘要:本曲轴滚压机的特点是采用强化滚压与滚压校直相结合,设计为三级变压液压系统。滚压过程中滚压力成阶梯型变化,实现自动定位、强化滚压、光整滚压三个过程。以提高滚压质量和滚压校直作用。即开始按较小的夹紧力进行滚压,以便曲轴定位;当滚压数圈后,滚压力增至最大值,做强化滚压;滚压至需要圈数后压力又降至一定值做光整滚压。再滚数圈,滚压循环结束。液压系统液压阀配置形式选择集成块式。液压集成块是安装各种液压元器件,并在其内部按液压原理图实现元件间孔道连通的复杂功能阀块,其结构紧凑,元件密度高,占据空间小,变化灵活,易标准化等特点。

Crankshaft Rolling strengthen the design of the hydraulic system
ABSTRACT
Abstract: The crankshaft rolling machine used to strengthen the characteristics of rolling and rolling straightening the integration of design for the three PSA hydraulic system. Rolling into the process of rolling pressure on the ladder-type changes, automatic positioning, strengthening rolling, rolling three-whole process. Rolling to improve school quality and rolling straight role. That is to embark on the smaller clamping force to roll in order to crank positioning when rolling a few laps later, rolling to the maximum pressure, so strengthening rolling, rolling to need a few laps after the pressure has to do a certain value Finishing rolling. Rolling again a few laps, rolling cycle ended.. Hydraulic system hydraulic valve configuration of choice for integrated block. Hydraulic Manifold is the installation of various ponents, and in its internal realization of the principle of ponents of plex functions of the channels connected valve block, pact, high-ponents, occupy small space, changes in flexible, easy to standardize And so on.
