专用冲压设备及液压系统设计 摘要 弯边机属于冲压设备，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。 本设计中弯边机的工作目的是将0.5mm的钢板弯成槽状，其工作过程如下：接料由汽缸完成，放到磨具上-开模-竖弯边-水平弯边-水平弯边缩回-定位模合拢受模，整过动作循环要求在20秒之内完成。它的主要工作参数有：竖弯边缸及水平弯边缸行程为100 mm；定位模缸的行程为80mm。此弯边机的主要组成部分有泵站、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个油缸组成，传动是平稳连续的。其中，竖直压紧部件是弯边机的重要组成部分，它的主要作用是压料和进行第一次冲压弯曲。 本设计中涉及大量计算推导，以及各种机械工程制图的运用，用计算和推导做为基础，直观图表作为表达方式，具体形象的展现液压系统在机械工具中的重要作用。 本弯边机从结构上看，元件单位传递的功率大，结构简单，布局灵活，能速换向和变速，元件易实现系列化、标准化。在大批加工、生产中可以起到高效、保质的效果。 关键词 竖直弯边；水平弯边；压紧部件；定位模 Special-purpose ramming equipment and hydraulic system design Abstract Curved side machine belongs to the ramming equipment, it uses the hydraulic transmission, mainly applies in the gauge block material curved side, before like refrigerators, shutter and so on. In this design the curved side machine work goal is steel plate curved Cheng Caozhuang who captures 0.5mm, its work process is as follows: Meets expects c to complete by the cylinder, - the die sinking - sets upright the curved on the one hand - level curved on the other hand - level the side to the grinding tool on curved side to retract - locates the mold to close up the mold, puts in order the operating cycle request to complete within 20 seconds. Its prime task parameter includes: Sets upright the curved on the one hand cylinder and the level curved on the other hand cylinder traveling schedule is 100 mm; The localization mold cylinders traveling schedule is 80mm. This curved on the one hand machine key component has the pumping station, the lathe bed, the column, vertical and the level curved on the other hand part, contracts the part and the localization mold part vertical and so on. The pumping station altogether has 10 cylinder compositions, the transmission is steady continuously. And, contracts the part is the curved side machine important component vertical, its leading role is presses the material and carries on the first ramming to be curving. this curved side machine structurally speaking. In this design involves the ma
