Description

平坦度测量辊
技术领域
本发明涉及一种用于轧制控制工艺中的控制装置;具体而言,涉及一种平坦度测量辊,它被设计成可压在轧制带钢上、且具有许多横跨于轧制带钢宽度方向上的测量区的活套挑,所述测量区分别由一个可顺时针摆动的且与测力机构一起工作的可转动支承的测量辊构成。
背景技术
DE-403166C2公开了一种在带钢轧机中作为带钢张力调节装置的这种活套挑。另外,带钢最好是无张力的即调节值为零。作为带钢张力调节装置的活套挑例如安装在轧机机架出口侧。它具有许多分布于宽度上的成对测量摇臂,每个测量摇臂一方面具有配属于带钢的测量辊而另一方面具有测力机构。活套挑或它的每个测量区原则上布置成天平式对称结构。两个并排平行间隔设置的平板形测量摇臂支承测量辊并具有通过导板拧紧的转动轴承。另外,在转动轴承的垂直下方还设置了一个用于空心调节臂的转轴。用许多螺钉如此调节转轴,即它使测量辊位于水平位置。为每个测量辊配备了两个测力机构,测力机构设置在一个测力摇臂上和空心调节臂上。空心调节臂同时是防翘起机构。由这种公知活套挑构成的测量区域要求测量辊在水平面内具有自由度。这可以借助设置在各测量摇臂轴上的摆动辊轴承而通过浮动支承方式实现。
支承测量辊的两个测量摇臂板在横向上只有较低的强度,从而必须在各测量区域或成对的测量摇臂板之间留有相对大的自由空间,以避免相互接触。由于测量摇臂板的强度低且浮动支承测量辊,所以出现了这样的危险,即当活套挑的测量辊受到偏心负载时,它转移出水平位置并由此通过侧向抬起的辊棱损坏轧制带钢。此外,由于测量辊处于倾斜位置,所以造成与测量摇臂的接触并造成损坏。特别是还会损坏测量辊轴承的润滑油路,这显然将导致轴承失效。由于测量摇臂与测量辊的相对摩擦接触而最终导致了测量不准确。基于此,活套挑具有许多旋转支承的且需要代价高昂的润滑处理的元件。另外,必须花时间通过许多埋头调节螺钉调节测量辊,而且需要经常调节,这是因为它们会由于外载荷和振动而松动或锁死。
发明内容
本发明的目的在于提供一种上述类型的平坦度测量辊,它不存在所述活套挑的缺陷且机构简单。
本发明的目的是这样实现的,各测量辊支承在摆动的空心杆架上。具有空心杆结构的杆架具有很高的刚度,此刚度避免了最好设置在连续支承轴上的测量辊的倾斜并同时可以使活套挑的各杆架部分彼此相邻设置。本发明的平坦度测量辊或活套挑与公知结构相比具有低很多的结构且重量轻。特别是由于测量辊部分质量很小,所以转动惯量很小,特别是在制造薄带钢时,这对带钢张力的调节特别有利。
本发明的一种结构为:杆架转点位于具有测力机构的轴上。该轴可为空心轴,这样可以减小质量。在轴前面设有许多测力机构,例如借助螺栓固定的压力测量盒以及终端测量区域即测量辊。为了在轧制带钢时使平坦度测量辊或活套挑摆动,至少在轴的一端设有调节缸,该轴还装有一个自动同步发送器。
在本发明的一个优选实施例中,杆架转点、相应的测量辊的转点以及设置在杆架转点下的测力机构的传力点近似地形成了等腰三角形。根据本发明,由于这三点通过框架彼此相连,因此拉力或压力作用到各点连线上,从而获得了最佳刚度并通过测量辊转点到杆架活动接头或转点较大的力臂获得了最佳传力效果。在此,测力机构中垂直地设置在杆架转点与传力点间的连线上。与在公知活套挑中将拉力传递到测力机构上不同地,带钢张力形成的压力有利地传递到测力机构上。
若在由转点和传力点形成的各杆架或各杆架部分的三角形之外有利地设置了防翘起机构,则可确保杆架顺时针或逆时针转动。例如,该防翘起机构可以包括插入杆架穿孔的并插入在轴接头中对准的孔中的螺栓。若承载带钢张力的杆架顺时针摆动,在杆架侧的螺栓头相对杆架具有空隙(如0.1mm-0.3mm)。预紧螺栓可以有选择地达到相同的目的,即允许顺时针运动而防止逆时针运动。本发明的平坦度测量辊结构允许通过松开在杆架下面的自由触及的防翘起机构而使一个或多个杆架逆时针运动,从而从活套挑中运动到自由触及的位置上。由此可以单独更换测量辊或整个杆架部分或测力机构,而不需要拆卸整个测量辊。
附图说明
从权利要求书和以下的说明书中给出了本发明的其它细节和优点,其中描述了一个本发明主题的实施例。其中:
图1在局部剖视图中示出了由多个杆架部分组装成的平坦度测量辊;
图2示出了杆架部分细节的俯视图;
图3示出了图2的杆架部分的侧视图。
具体实施方式
如图1所示,一个例如在输出侧设置在带钢轧机机架后的平坦度测量辊1形活套挑具有相邻地设置在一个公用轴2(空心轴,见图3)上的多个杆架或杆架段3。调节缸的活塞杆4与图1所示轴2的左端连接,从而通过轴2的摆轴5调节杆架3,即在轧制带钢(未示出)时使杆架3摆动。借助与摆轴5或轴2连接的自动同步发送器监控平坦度测量辊或活套挑1的调节数值。
从图2和图3可进一步看出,杆架3是空心结构以便提高其刚度。在各远离轴2的杆架3前端上支承着通过连通轴7支承的并绕转点8转动的测量辊9。与杆架上侧拧在一起的导板10作为耐磨件使轧制带钢在其上受到导向地通过。杆架3通过转动铰点形转点11设置在轴2的凸轮形附件12上。防翘起机构13确保了杆架3按顺时针方向转动而不能逆时针转动。在防翘起机构13的上方具有配属于轴的测力机构15的传力点14。
除了由于当出现带钢张力时摆动的转点11外,杆架3还作为一体部件地具有测量辊9的转点和传力点14。这些点之间的连线16-18(见图3)近似地构成了等腰三角形。通过连线16即杆架3转点11与测量辊9转点8之间的连线形成的较大力臂获得了将作用于测量辊9上的带钢张力传递到测力机构15上的最佳传递效果。
尽管平坦度测量辊或活套挑1是很紧凑的且是由许多标准的高刚度杆架构成的,但在转点7、11或传力点14之外的防翘起机构仍然可以通过简单方式自由触及任一个杆架以便进行成套的更换或仅更换测量辊9。在松开防翘起机构13后,所需的杆架3沿逆时针方向转移出来,即按图1的布局绕转点11向上转动出来而不需要拆卸整个平坦度测量辊或活套挑1。
