由长治锻压机床厂承担的国家“八五”科技攻关项目:数控技术及装备开发与研究专题——管材柔性加工单元经过该厂科技人员历时4年多的奋战,近日通过了由机械部科技质量监督司和机械基础装备司及有关科研院校组成的验收组验收.在执行攻关任务过程中,该厂积极与大专院校和科研院所联合,集中优势开发出了数控系统,掌握了与之相关的联机技术,在广泛进行深入探讨和工艺试验验证的基础上;撰写了“管材变形机理研究及弯管模具数学模型的建立”、“管形数据回弹修正研究报告”、“高速大惯量精确定位”、“弯管模具结构型式”等成果论文,并在样机验证对管型工件仿型加工,建立了包括16,25,40,76,90,120,220,275毫米等多种规格的不同管型的相关数据库.
From the Changzhi forging machine tool plant bear “85” key scientific and technological projects: CNC technology and equipment development and research topics - flexible pipe unit after the plant science and technology lasted more than 4 years of hard work, recently adopted by the Ministry of Machinery Science and Technology Quality Supervision Division and the basic equipment and mechanical equipment and acceptance of the acceptance of the research group composed of acceptance.In the implementation of the task of tackling the task, the plant actively with universities and research institutes jointly focused on the development of a CNC system, mastered Related online technology, based on a wide range of in-depth discussions and process validation tests based on the written “pipe deformation mechanism and the establishment of elbow mold mathematical model ”, “tubular data springback correction research report ”,“ High-speed large inertia precise positioning ”, “ elbow mold structure type ”and other results of the paper, and in the prototype verification of the tubular workpiece profiling processing, established including 16,25,40,76,90,120,220,275 mm A variety of different specifications of the tube-related databases.
