1、鞍山科技大学本科生毕业设计（论文）第1页1700冷轧机组卷取机设计摘要卷取机是轧钢成卷生产不可少的设备。保证卷取机顺利工作对提高轧机生产率有很重要意义。冷轧机组中，卷取机用于卷取带钢成钢卷。采用恒张力轧制，可以提高带钢质量。这次设计是1700冷轧机组卷取机设计，其用于二机架冷轧机组中。首先，选择卷取机的设计方案，并对设计方案进行评述。由于冷带钢卷取张力大，采用四棱锥卷筒结构。用液压缸移动斜楔进行胀缩。将四棱锥体单独加工装在卷筒轴上，这样改进，加工方便。当锥体磨损后可以单独更换。这样，可以降低设备维修

2、费用。另外，四个扇形块边采用搭接技术，防止卷筒胀开后出现空隙，减少钢卷局部压扁，提高钢卷质量。去掉钳口，采用助卷器卡紧带钢头部，方便卸卷。这次设计，进行主电机容量的计算和选择。对斜楔进行受力分析。计算带钢卷取过程中对卷筒的压力并计算卷取轴弯曲强度，对传动齿轮进行设计计算。对支承轴承进行选择和校核。采用合理的润滑方案、润滑方法和控制技术，使卷取机技术先进，经济合理。强度足够，有广泛的使用价值，可用于酸洗、热处理、镀锌和镀锌机组中。关键词：卷取机，斜楔胀缩，助卷鞍山科技大学本科生毕业设计（论文）第2页1
