【摘要】：焊丝盘,是用来收集和储存焊丝的工具,现如今国内焊丝盘还是以塑料焊丝盘为主流,但是随着环境日益恶化,以及可持续发展的需要,环保成了必须要走的路,目前有很多国家对于进口产品的环保性提高了执行标准,要求采用环保经济的金属焊丝盘代替传统塑料焊丝盘,金属焊丝盘越来越多的应用在了线材、焊材、电缆等各种线材的包装上。随着焊丝盘需求量和焊丝盘进出口量的不断增加,对弯曲工件精度和结构的要求也来越高。因此,弯丝设备的自动化对产品的质量起着至关重要的作用。传统的国内数控弯丝机的控制系统主要是以单片机或PLC为控制核心,在功能上主要完成较为简单的二维空间上的弯曲,实现三维弯曲比较困难,无法满足线材包装上的需要。本文针对较为复杂的三维形状,采用三菱PLC和触摸屏为控制方式对金属焊丝盘数控系统进行研究开发。首先对国内外数控弯丝设备控制系统的研究现状做了简单的介绍,在课题组前期机械结构研究的基础上,对金属焊丝盘弯丝设备的主要机械结构的工作原理进行了介绍,并给出了设备的总体控制方案。其次,根据金属焊丝盘数控设备加工过程的控制要求,对金属焊丝盘数控设备控制系统的软、硬件进行了设计,包括:PLC控制模块、步进电机控制模块、气动回路、人机界面等。为适应网络化制造的要求,对金属焊丝盘数控设备的车间群控进行了研究设计。最后,对编写的PLC和触摸屏程序进行在线仿真验证,搭建模拟实验台,对设计方案的可行性进行实验验证,总结全文并展望未来的研究工作。
[Abstract]:Wire pads are tools for collecting and storing wires. Nowadays, domestic wire plates are still dominated by plastic wire pads. However, with the worsening of the environment and the need for sustainable development, environmental protection has become a must. At present, many countries have improved the implementation standards for the environmental protection of imported products, requiring the use of environmentally friendly and economical metal wire pads instead of traditional plastic wire plates. Metal wire pads are increasingly used in wire and welding materials. Cable and other wires on the packaging. With the increasing demand for wire disk and the increasing import and export of wire plate, the higher the precision and structure of bending workpiece is. Therefore, the automation of wire bending equipment plays a vital role in the quality of products. The traditional control system of domestic numerical control wire bending machine is mainly based on single chip computer or PLC. It can not meet the needs of wire packing because of the simple bending of two-dimensional space and the difficulty of realizing three-dimensional bending. In this paper, the numerical control system of metal welding wire disk is researched and developed by Mitsubishi PLC and touch screen. Firstly, the research status of the control system of CNC wire bending equipment at home and abroad is briefly introduced. Based on the previous research of mechanical structure of wire bending equipment, the working principle of the main mechanical structure of wire bending equipment for wire plate is introduced. The overall control scheme of the equipment is also given. Secondly, according to the control requirements of the machining process of the metal welding wire disk NC equipment, the software and hardware of the metal welding wire disk numerical control equipment control system are designed, including the control module of the 1: PLC, the step motor control module, the pneumatic loop, the man-machine interface and so on. In order to meet the requirement of networked manufacturing, the group control of NC equipment for wire plate is studied and designed. At last, the PLC and touch screen program are simulated and verified online, the simulation experiment bench is built, the feasibility of the design scheme is verified, the full text is summarized and the future research work is prospected.
