第 PAGE III页液压弯管机系统PLC控制设计 摘要液压弯管机一种新型的具有弯管功能及起顶功能的弯管工具。具有结构合理、使用安全、操作方便、价格合理、装卸快速、便于携带、一机多用等众多优点，在国内液压弯管机市扬占据很大份额，主要用于工厂、仓库、码头、建筑、铁路、汽车等安装管道和修理。它除了具有弯管功能外，还能卸下弯管部件(油缸)作为分离式液压起顶机使用。整个系统由机械系统、液压系统和控制系统等组成，可以完成复杂空间形状的空心管加工。采用PLC作为控制中心直接与硬件交互。本课题利用液压传动的基本原理，拟定出合理的液压系统图，通过经过必要的计算,确定液压系统的参数，然后按这些参数来选用液压元件的规格并进行系统的结构设计来达到设计一套完整的液压弯管机的目的。该弯管机系统包括液压泵站和PLC控制两部分：液压泵站部分设计包括液压泵站原理图设计以及泵站上各主要元件的选型和相关参数设置；PLC控制部分主要包括电气控制原理图设计、PLC控制系统设计级软件仿真，结果符合设计要求。 关键词：液压弯管机；PLC；液压泵 全套图纸加153893706 The Design of Control System in Hydraulic Pipe BenderAbstractHydraulic pipe bender is a kind of novel has the function of elbow pipe and the top tube bending tools. With reasonable structure, the use of safe, convenient operation, reasonable price, loading and unloading fast and easy to carry, one machine, and many other advantages, a large share in domestic hydraulic pipe bender, Yang, mainly used in factories, warehouses, docks, building, railway, automobile and other pipeline installation and repair. It not only have the functions of bend, still can remove pipe bending parts (cylinder) as a separate hydraulic jacking machine use. The whole system consists of mechanical system, hydraulic system and control system, etc, can complete the complex space in the shape of a hollow tube processing. Adopting PLC as the control center interact directly with hardware. This topic by using the basic principle of hydraulic transmission, and formulate a reasonable hydraulic system diagram, through after the necessary calculation, determine the parameters of the hydraulic system, and then according to these parameters to choose the specifications of the hydraulic components and system structure design to achieve the purpose of the design of a complete set of hydraulic pipe bender. The pipe bending machine system consists of hydraulic pump station and PLC control of two parts: hydraulic pump station part of the desi
