辊弯机自动控制系统的设计和实现
|
摘要
辊弯机是很多制造行业中应用广泛的板(型)材成形加工设备。由于辊弯工艺本身所具有的复杂性,目前国内辊弯工艺及辊弯设备的技术水平还比较低。为了能从根本上改变目前国内辊弯设备在操作方式上的手工依赖性强、成形精度差和工作效率低的缺点,我们设计并实现了基于虚拟仪器技术的辊弯机自动控制系统。整个系统以工业控制计算机为核心,以数据采集为基础,包含了计算机、自动控制、测试测量和机械工程等多种技术,系统的研发过程采用了目前国际测控领域中先进的虚拟仪器开发平台─LabWindows/CVI。
本文在分析系统的设计方案的基础上,主要从系统的硬件和软件设计这两个方面阐述了系统的实施技术细节,并重点分析了几个关键技术难点及其解决方法。
系统的研制成功极大地提高了产品的质量和生产效率,并且成本低廉、结构简单,开发周期较短,对设计和研制类似设备的自动控制系统具有较高的参考价值。
In manufacturing sectors, the cold roll forming machine is in wide use for the forming of slabs. In view of its own complexity, the workmanship and technology of domestic cold roll forming machine are still immature currently. Based on the technology of Virtual Instrument, the Automatic Control System has been designed and put into practice, aimed at fundamentally improving the current operating patterns, which is heavily dependent on manual work, imprecise in formation and low in productivity. On the basis of data acquisition, the whole system is industrially-controlled-computers-centered, including such technology, say, computers, automatic control, test and tryout, mechanical engineering and etc. Labwindows/CVI, the advanced virtual instrument in the international testing and controlling area, is embodied in R&D of the system.
The essay, on the basis of analysis of the system design, elaborates on how to operate details of the system upon the design of hardware as well as software. Moreover, it stresses several key technical difficulties and the solutions.
The success of the system significantly enhances the quality and efficiency in production, boasting low cost, simple structure and short-term development cycle. Plus it offers high value of reference to design and develop the equipment, akin to the automatic system.
