1、学士学位论文I学士学位论文学士学位论文弯边装置液压系统设计弯边装置液压系统设计摘摘 要要弯边装置属于冲压机械设备，它采用液压传动，主要应用于对板型材 料弯边，如冰箱的前门板等，此弯边装置的工作目的是将 0.5mm 厚的钢板 弯成槽状，其工作过程如下：接料（由气缸完成）到模具上开模竖直 弯边水平弯边水平弯边缸缩回竖直弯边缸缩回定位模合拢闭模， 整个工作循环要求在 20s 之内完成。它的主要工作参数有：竖直弯边缸及 水平弯边缸行程均为 100mm；定位模缸的行程为 80mm。此弯边机的主要 组成部分主要有泵站、床身、立柱、竖直和水平弯边部件、竖直压紧部件 及定位模部件等。泵站总共有 10 个油缸组
2、成，传动是平稳连续的。其中， 竖直压紧部件是弯边装置的重要组成部分，它的主要作用是压料和进行第 一次冲压弯曲。本弯边装置从结构上看，元件单位传递的功率大，结构简 单，布局灵活，能迅速换向和变速，元件易实现系列化和标准化。关键词关键词 竖直弯边；水平弯边；压紧部件；定位模缸学士学位论文IIThe design of the curved side machines system of the hydraulic pressureAbstractThe curved side machine belongs to the stamping engine equipments, it adoptio
