摘要:卷板机（Rolling Machine）是对板材进行连续点弯曲的塑形机床，具有卷制O型、U型、多段R等不同形状板材的功能。以把金属板材卷制成筒形、弧形、扇形、锥形等工件，是专门用于金属板材弯曲、成型、校正的一种通用设备，在造船、化工、锅炉、水电、压力容器以及机械制造各行业中，有着广泛的应用。
随着工业制造业的发展，对于卷板机能够生产的O型、U型、多段R型板材需求量越来越大。卷板机是建造化工厂、海上石油平台等的必备设备，卷板机功率较大，在生产中以交流电机作为驱动。老式的卷板机需要人工操作，这种操作模式生产效率低下，且不能达到可靠稳定、安全生产、高质量的生产要求。
随着PLC的应用，使得工业生产可以脱离人力操作，实现电气化控制。电气化自动化控制后，卷板机的操作简单方便，人性化的人机界面能很方便的反应实际生产情况和完成操作。本次毕业设计为能满足工业生产要求设计一种卷板机控制系统。24560

The design of control system of plate bending machine
Abstract: Bending machine (Rolling machine) is the plates by continuous point bending shaping machine, with rolling O type, U type, and multisession different shipmate function. The metal sheet rolled into a barrel shaped, curved, fan-shaped, conical work piece, is designed for the sheet metal bending, forming, the correction of a universal equipment, shipbuilding, chemical, boiler, power, pressure vessels and machinery manufacturing industries, has a wide range of application.
With the development of industrial manufacturing, for bending machine capable of producing O, U-shaped, multi-plate type R growing demand.Plate bending machine is necessary equipment for construction of chemical plants, offshore oil platform, power machine, in the production of AC motor as driving. Bending machine old-fashioned manual operation, this mode of operation and low production efficiency, and cannot meet the requirement of production is reliable and stable, safe production, high quality.
With the application of PLC, the industrial production can be separated from the manual, electrical control. Electrical automation and control, machine operation is simple and convenient, user-friendly man-machine interface can be very convenient reaction of actual production and complete the operation. This graduation design is to meet the requirements of industrial production to design a control system of plate bending machine.
