单柱液压剪板机结构及液压系统设计 SINGLE-COLUMN HYDRAULIC SHEARING MACHINE STRUCTURE AND HYDRAULIC SYSTEM DESIGN PAGE I PAGE I 摘要 近年来，随着工业的快速发展，各个行业对的金属板料需要越来越多。为此，金属加工设备也有更高要求。其中，剪板机就是具有代表性的机械加工设备之一。在分析现状和现场调研的基础上，从机械剪板机和液压剪板机中选择优势较大的液压剪板机作为设计对象。 本文设计了一种简单的剪板机，可以剪切4毫米厚、500毫米宽的板材。这次设计的剪板机可以分为两个部分。第一个部分为机械结构部分，第二个部分为液压系统设计部分。在机械结构部分中，各个部件的连接方式主要以使用螺栓连接为主。并且在一些部位上进行焊接，以此来保证整体结构的稳定。本次设计的结构由五个部分组成，分别为立柱、横梁、刀架、刀片和托板。重点就机架、刀架等重要部件进行了设计。同时在设计的过程中，用到了液压系统。本次设计将一个液压缸作为动力源，上刀架在动力源的作用下进行剪切运动。通过了解液压闸式剪板机，完成了刀架的设计、机架的设计、剪切力计算、液压系统的设计、关键零件计算与校核，最终设计出结构简单，操作简便，同时经济、合理的液压剪板机。 关键词 刀片；液压缸 ；液压剪板机 ；刀架； 全套图纸加扣 3346389411或3012250582 PAGE III PAGE III Abstract In recent years, with the ?rapid expansion of industry, more and more metal sheets are needed in various industries.. For this reason, metal processing equipment also has higher requirements. Among them, the shearing machine is one of the representative mechanical processing equipment. Based on the analysis of the current situation and on-site investigation, the hydraulic shears with greater advantages are selected as the design objects from the mechanical shears and hydraulic shears. This paper designs a simple shearing machine that can cut 4 mm thick and 500 mm wide plates. The shearing machine designed this time can be divided into two parts. The first part is the mechanical structure part, and the second part is the hydraulic system design part. In the mechanical structure part, the connection method of each component is mainly using bolt connection. And welding is performed on some parts to ensure the stability of the overall structure. The structure designed this time is composed of five parts, namely upright, beam, knife holder, blade and pallet. Focus on the design of important components such as frame, knife holder. At the same time, a hydraulic system was used in the design process. In this design, a hydraulic cylinder is used as the power source, and the upper tool holder performs shearing movement under the action
