2、类：按用途不同、按传动系统、按操纵系统、按平板加热方式、按结构不同。 柱塞是平板硫化机的主要零部件之一，它与工作缸、密封装置、压紧法兰等组成了传递压能的部件，主要是将液体的压能转变成带动平台或可动横梁运动的动能。 工作缸是平板硫化机传递力量的主要零件，属于高压下操作的厚壁容器。对于缸体的要求是保压性能好，无泄漏，成本低，导向部分耐磨。密封装置是工作缸与柱塞组合件的重要组成部分，平板硫化机能否者正常工作，在很大程度上取决于工作缸密封结构的完善程度。 热板为平板硫化机重要部件之一，其主要作用是向模具或制品提供热能和压力，保证制品硫化过程中所需的温度和压力。 可动平台与柱塞连接，当柱塞受液压而升降时
3、，平台亦随之升降，当与上部横梁或热板接触则平台上均匀受压，平台的变形会影响平板硫化机的精度及硫化制品的质量。上横梁和底座的作用是来承受平板硫化机加压时所产生的作用力，这些零部件用立柱连在一起，并形成一个坚固的封闭构架。连接方式为柱塞在工作缸内滑动，为了防止漏油在缸的上方放置两个密封圈，一个与法兰相接触，另一个与柱塞相接触，柱塞上部与可动平台连接，可动平台与下加热板之间有隔热板用螺钉固定，上横梁与上加热板也是中间有隔热板用螺钉固定，上横梁和底座之间用立柱和螺母固定，来确定整个平板硫化机稳定性。 它的基本工作原理是：油泵通过管道进入缸内使柱塞拖动可动平台缓缓上升（但是它的运动速度比较缓慢，往往在底
4、座上方加入两个辅助油缸，来提高柱塞的上升和下降速度），直至上热板上升到对制品加压的作用，进行保压硫化，完成硫化作用缸内油由管道送出，使可动平台带动下热板放回。这就是整个硫化过程。 关键词：硫化机；液压传动；底座AbstractVulcanizing press for the whole column as column hydraulic vulcanizing machine.
