钢坯火焰清理机氧化皮裂纹清理装置设计.docVIP

摘 要 钢坯清理厂目前所用的设备为老式的清理机，它是上世纪九十年代产品，设备老化，维修困难，加工零件精度低，加工范围小，功能已很难适应新的工艺及船用工件，所以改造时主要从以上几方面考虑。经过与工厂协商，在改造中主要解决这些问题，改装割炬升降装置，进而适应钢坯厂大型钢坯的加工。改造后应达到通用性好，可进行直线及任意曲线的清理，可配置任何形式的割炬。精度高，改造后的数控火焰清理机运行精度、定位精度及转角处精度均要得到保证。清理质量好，清理机运行平稳，定位精度高。自动化程度高，切割全过程自动控制。数控系统功能齐全。 本论文的工作重点是数控火焰清理机机械本体的改造，通过对机械本体的不合理地方重新设计和计算机数字控制技术应用，完成了数控火焰清理机的改造，并且在实际中进行了运行和调试．本论文的工作及贡献 主要有下面几个方面； 1．进行了机械方案设计、计算与分析，其主要内容包括机械本体，传动 系统及加装的自动调高，和割炬升降装置改装等。。 2．对改造后的数控火焰切割机进行了调试和运行，参数设置，诊断分析 以及精度检测。’ 关键词：数控火焰清理机、改造、机械本体、电气控制 加工 ABSTRACT Billet cleaning plant equipment currently used to clean up the old machine, it is the nineties of last century products, equipment aging, maintenance difficulties, low precision machining parts, machining range of small, function has been difficult to adapt to the new technology and marine artifacts, so transformation of the above areas is a major consideration. After consultation with the factory, in the transformation  Mainly to solve these problems, the modified torch lifter, and then adapt to large-scale billet steel billet plant processing. After transformation, should reach common good, can be straight and clean up any curves that can be configured to any form of cutting torch. High precision CNC flame transformed cleaning machine running accuracy, positioning accuracy and precision of the corner have to be guaranteed. Clean-up of good quality, clean machine running smoothly, high positioning accuracy. High degree of automation, automatic control of the whole process of cutting. Numerical control system fully functional.  Focus of this paper is the numerical control flame cleaning machine mechanical body transformation, by mechanical body to re-design and unreasonable where technology computer numerical control, CNC flame cleaning machine to complete the transformation, and carried out in practice running and debugging . Work and contribution of this paper There are the following aspects; 1. For the mechanical design, calculation and analysis, which mainly
