摘要
现在各国工业迅猛发展,钢铁企业是国民经济的主要支柱,它的发展状况很大程度上可以反映出国家的实力。现代钢铁冶金业发展的一个着眼点就是在对钢材的处理速度。圆盘剪切机就是其中的一台重要设备。
圆盘剪切机通常设置在精整作业线上,用来将运动着的钢板的纵向边缘切齐或切成窄带钢。根据其用途可分为两种类型:剪切板边的圆盘剪和剪切带钢的圆盘剪。
本文通过对圆盘剪切机及相关设备结构进行了深入了解,并从材料力学、动力学和经济学的角度出发,对圆盘剪切机的主传动系统,压下系统、侧间隙调整机构进行了设计。重点包括电动机的计算选娶轴和齿轮的设计,以及其他传动装置和执行机构的设计等,同时对部分主要零部件进行了强度校核。本次设计的改进点:首先,在径向间隙调整机构连杆机构,其二,侧向间隙调整增加自锁装置。其三,宽度调整采用行星齿轮减速机。最后增加了测速机构。本圆盘剪切机可普遍用于横切机组、酸洗机组等。
关键词:开口度调整机构,圆盘剪切机,带钢,压下装置,强度校核
