Description

中厚板轧机机架辊装置
技术领域
本实用新型所述的中厚板轧机机架辊装置,涉及冶金行业中厚板轧机的一种辅助装置。
背景技术
机架辊又名牌坊辊,是与主机轧制过程中联系最紧密的设备之一。它的作用是将板坯顺利送入轧机辊缝并接受轧出的轧件,这就决定了它的重要性,是轧制过程中不可缺少的设备,机架辊工作条件恶劣,受冲击,负荷大。损坏是难免的,现代设计思想不再是尽量加大安全系数,既然损坏难以避免,就要从缩短更换时间,方便维修入手设计结构,又由于不同的轧机轧制力不同,板坯规格不同,成品规格不同,所以机架辊的设计型式也不同。
中厚板轧机所用坯料长度较短,需要横轧,以前一般设计为3根机架辊集体传动,但使用效果均不理想,经常出现各部件损坏。比如4200四辊轧机,自投产以来,机架辊频繁出现各部件的损坏,如机架辊接轴的扭曲变形,扁头折断,叉头扳开,辊颈滚键或断裂等。还有的机架辊,出现过断辊情况和齿轮分配箱齿轮损坏,而齿轮分配箱工作环境恶劣,齿轮损坏是最大问题。
国外SMS中厚板轧机3根机架辊,为1根单传动和2根集体传动的复合形式,使用效果较比3根机架辊集体传动要好些。针对上述现有技术中所存在的问题,研究设计一种新型的中厚板轧机机架辊装置,从而克服现有技术中所存在的问题是十分必要的。
发明内容
鉴于上述现有技术中所存在的问题,本实用新型的目的是研究设计一种新型的中厚板轧机机架辊装置,从而解决中厚板轧机3根机架辊集体传动所带来德问题。本实用新型所述的中厚板轧机机架辊装置是由轧机前后各3根机架辊所组成。其结构在于每个机架辊采取单独传动。机架辊由机架辊本体、卡紧装置和传动装置组成。传动装置由电机、联轴器、减速机和十字轴万向接轴组成并依次安装。机架辊本体和十字轴万向接轴相连接。机架辊本体由卡紧装置固定在轧机机架上。本实用新型所述的机架辊本体下面装有冷却水喷嘴。在前机架辊下部还装有高压水除鳞喷嘴。
本实用新型为中厚板轧机机架辊装置,设计为3根机架辊,每根单独传动,配有齿轮减速机,取消了齿轮分配箱,此结构形式机架辊在此系列中厚板轧机中为国内外首创。机架的单独传动具有很大的意义,因为机架辊的更换很不方便,采用单独传动,在使用过程中,如果有一根辊子的传动出现问题,则还可以继续进行生产,可以不更换,若采用集体传动,如果齿轮箱出现问题,则只能更换。
本实用新型具有结构新颖、机架辊更换方便、安全实用等优点,其大批量投入市场必将产生积极的社会效益和显著的经济效益。

具体实施方式
本实用新型的具体实施例如附图所示,轧机前后各安装3根机架辊,每个机架辊单独传动。每个机架辊均由机架辊本体、卡紧装置和传动装置组成。传动装置由电机、联轴器、减速机和十字轴万向接轴组成并依次安装。机架辊本体和十字轴万向接轴相连接。机架辊本体由卡紧装置固定在轧机机架上。在机架辊本体下面装有冷却水喷嘴,用以冷却机架辊辊身。在前机架辊下部还装有高压水除鳞喷嘴,对钢板进行二次除鳞。。
