卷板机设计说明书.doc

I 摘要卷板机是一种将金属板料弯卷成筒体、锥体、曲面体或其他形体的一种专用锻压机械设备,广泛用于锅炉、造船、化工、金属结构及机械制造行业。本课题的研究宗旨在改进旧式卷板机的不足,提高生产率、降低工人劳动强度,满足厂方对板料加工的生产需求。本文主要研究内容:分析了对称式三辊卷板机的受力状况。在对卷板过程变形力能参数分析的础上, 将其受力与设备的驱动功率直接建立联系, 通过功能转换计算,得出了卷板机主驱动系统的驱动功率的一种计算方法。经算例分析证明:该方法简化了卷板机选择设备动力的功率计算,计算结果更为符合实际。关键词:卷板机,受力分析,驱动功率 II STRACT Roll Machine can bend metal plate toaspecial shape, such ascolumn, conecamber and soon, which iswidely applied toboiler manufacture, shipbuilding,chemical industry and machine manufacture. decrease the work intensity andcontent the demand ofthe factory for plate coiling. The bearing force analysis ofthree rollers veneer reeling machine ofsymmet rical type was carried out .Onthebase ofthe ability analysis intransform , the direct contact between bearing force and driving power onequipment wasestablished. Through the function conversion calculation ,the calculating method ofdriving power onthe main drivesystem was given. The deducing process was simple and could beunderstood easily.
