Description
本发明涉及一个万能轧机机座,它在两个互相平行的轧辊支架上放置可调节的水平轧辊和垂直轧辊。
用此类连续运行或可逆工作的万能轧机机座能够轧制各种不同的型材,例如:工字型材和槽钢或钢轨。此类万能轧机机座的水平轧辊和垂直轧辊组借助于安装块安装在支架横梁的开口空间,在该处水平轧辊的安装块成对地支持住上、下横梁。用若干压紧螺母通过与之配合的、轴向不能移动的、可转动的且在轧制轴线两侧面对面布置的压下螺丝把上下横梁固定住。为了在更换轧辊时不再从轧机机座上拆下横梁,一种为人所熟悉的万能轧机机座的结构是把上横梁分成两段,这样,能够将横梁向外转出并在轧辊更换完毕后再将其转回原位,最后用其余的部件锁定。在转出横梁时,能够容易地接触放置轧辊的安装块并能够穿过开口空间将其从机座上拆下。在这种结构的万能轧机机座上,除了用于更换轧辊的安装块以外,为了转动或者转出横梁,还需要一些附加的转动机构,例如:附加的转动液压缸。
本发明的目的在于创造一种开头所称的、结构简单、操作方便的万能轧机机座。
根据本发明,上述任务是这样解决的:水平轧辊直接置于安装在轧辊支架上的轴承内,而不需借助于安装块;由传动元件带动的位于操作侧的轧辊支架可以带着轴承沿着水平轧辊的轴向离开另一个轧辊支架;位于盒中的垂直轧辊插在与轧辊支架固定在一起的导向架中。本发明的基本思路在于通过移动操作侧的轧辊支架获得一种完全舍弃安装块的万能轧机机座,在其他种类的轧机机座上这种移动已为人所熟悉。在操作侧的轧辊支架移开后,不仅使水平轧辊,而且使垂直轧辊也敞开,并使互相分开的轧机机座的内部能够容易地接触到。根据本发明制造的、全新结构的万能轧机机座能取消其他类型的轧机机座在更换轧辊(尤其是垂直轧辊)时所必需的安装块,因为当轧辊支架固定在一起的导向架能够完成在其他类型轧机机座中由垂直轧辊安装块所承担的全部任务。
装有垂直轧辊的盒能够直接放在轧辊支架上对轧制工作所需的安装位置上,即插进导向架,也就是说不再需要借助于安装块。因此,导向架具有从内侧穿过轧辊支架进入盒式空间的优点,例如:采用容易***的滑动导轨的形式。
建议用拉杆把导向架与轧辊支架固定在一起。虽然也可以把它们做成一体的铸件,但是,多元结构具有加工技术上的优点,特点是由钢锭制成的轧辊支架和导向架可以采用经济的烧熔加工方法并因此可以采用简单的钢结构。用两根或四根拉杆把导向架拉紧并水平地固定在轧辊支架上,使其能够承受轧制压力。
本发明把导向架分成两部分,一部分是盒形部分,另一部分是从外侧装上的横梁。在组装导向架时,用拉杆把横梁和盒式梁固定在轧辊支架上。导向架的这种二元结构具有能够在横梁中配置垂直轧辊调节装置的优点。
为了使本发明的万能轧机能够做好可逆运转的准备,推荐在连续运行的机座上安装垂直轧辊调节装置,它由一个楔形调节器和一个用于抵抗由盒传过来的加载冲击的附件组成。连续运转的万能轧机机座只需进行一次性的调节,把附件从后面在腹板区域内接到盒上。附件能平衡垂直轧辊的扭转程度并能够调节不同宽度型材的轧辊间隙。而楔形调节器则用于微调,例如:当调节量为±5mm时,能够修正轧辊的磨损和万能轧机机座的弹回率。
由于万能轧机机座的结构简单,所以用手就能够进行各种调节,例如:通过安装在调节楔上的棘轮;当然也可以用液压马达或电动机,后者主要用于可逆工作的万能轧机机座。在这种情况下,在横梁和盒之间、在使用机械楔形调节器时安装附件的地方装上一个液压缸;这样,整个横梁可向盒形部分进行调节,因此,装有垂直轧辊的盒也能够调节了,例如:采用安装在机械同步传动调节螺母中的两个调节丝杠的形式。
如果在盒和轧辊调节装置之间安装一个U形支撑件,则它们就能够支承垂直轧辊向后的也就是在轧辊间隙或轧辊轴线的扩散面上的轧制压力,因为该轧制压力是通过U形支撑件的桥形截面传递的,它的接触面积较大。盒本身以及用它来装载放进、取出导向架的更换件由一个上板和一个下板组成,并包括装在板上的承载轴、轴承和垂直轧辊。
本发明的万能轧机机座可用单件的水平轧辊驱动。然而,如果用拉杆把可分离的水平轧辊紧固成一个整体,则会使这种结构的万能轧机机座更简单、更经济,因为它在辊体磨损后不再需要更换整个水平轧辊,而是仅仅更换辊环。
水平轧辊上装有受蜗轮蜗杆传动装置调节的偏心轴套,通过用于转动偏心轴套的蜗轮蜗杆传动装置能够把水平轧辊调节到希望的位置。
如果在盒朝向轧辊间隙的内侧面上安装一个环状的、用于承受进、出轧件侧向板加载冲击的夹持器,则藉助于侧向板同时通过夹持器(环状框架)把盒用液压向后压向调节装置并因此达到平衡。
下面按照图中描绘的实例详细地解释本发明。在附图中:
图1根据本发明的万能轧机机座正视图和沿着图2中Ⅰ-Ⅰ线的剖面图;
图2根据图1所示的万能轧机机座的侧视图;
图3沿着图1中Ⅲ-Ⅲ线剖开的万能轧机机座的俯视图;
图4根据图1所示的万能轧机机座的Ⅳ-Ⅳ剖面图。
如图1所示,万能轧机机座1在传动侧和操作侧各有一个轧辊支架3和4,前者固定在基础底板2上,后者是可移动的,二者彼此平行排列。为了移动或移开轧辊支架4,有一带有活塞杆6的调节缸5作用在轧辊支架4上。轧辊支架4离开轧辊支架3后的位置在图1中用点划线表示(对照用4′标注的轧辊支架)。在轧辊支架3、4上各有一个上水平轧辊7和一个下水平轧辊8以及两个垂直轧辊9(没有安装块)。
水平轧辊7、8由几部分组成(参见图1的上半部分),其中包括两个承载轴11、12,它们通过轴承13分别安装在传动侧轧辊支架3和操作侧轧辊支架4上。水平轧辊7、8中间夹着辊环14,它们被从操作侧穿进的、然后穿过承载轴12的、最后延伸至承载轴11的拉杆15拉紧成一个整体。水平轧辊7、8的轴承13直接放在轧辊支架3、4上;当然,这些轴承是置于偏心轴套16中,偏心轴套16又位于滑动套筒17中;此外,偏心轴套16上装有一个蜗轮18,它可通过蜗杆19藉手动驱动。上、下水平轧辊7、8蜗轮蜗杆传动装置21(蜗轮18和蜗杆19)用一个公用万向轴22连接在一起;上水平轧辊的蜗轮蜗杆传动装置21通过万向轴22A从传动端轧辊支架3连接到操作端轧辊支架4上,因此,它们在机械上是同步的(参见图2和图3)。为了调节水平轧辊7、8或轴环14,可转动蜗杆19,通过蜗轮18和偏心轴套16把蜗杆的运动传递到多单元组合的水平轧辊7、8的承载轴11、12上,根据蜗轮蜗杆传动装置21的转向,水平轧辊7、8彼此分开或靠近,从而达到调节水平轧辊7、8或辊环14的目的。
同水平轧辊7、8一样,垂直轧辊也可以不借助于安装块直接安装在轧辊支架3、4上,确切地说是放在旁边处于水平位置的导向架23中。导向架23由两部分组成,包括一个盒形部分24和一个从外侧装在其上的横梁25(参见图3)。图4个拉杆26把导向架23(即盒形部分24和横梁25)固定在轧辊支架3、4上,使其能够承受轧制轧件时产生的径向轧制压力。导向架23有一盒式空间27,当把轧辊支架3、4彼此分开后并处于图1点划线所示的轧辊支架4′的位置时,能够从内侧穿过轧辊支架3或4把盒29插进上述盒式空间27。盒29由上、下板组成,且装有一个垂直轧辊9及其承载轴28。盒29布置在一个U形支撑件30中,以它的腹板朝外指向横梁25而***进盒式空间27。这样,通过支撑件30间接地加大了导向架23的横梁25与盒29的接触面积。在横梁25中装有垂直轧辊调节装置31,它由一个楔形调节器32组成,用手转动丝杠33可以调节调节楔。用于微调的楔形调节器32经过附件34把调节力传递到盒29上,进而施加给垂直轧辊9,附件34位于横梁25和盒29之间固定在支撑件30上,它用粗调。
在盒29朝向轧辊间隙或者轧制轴线35的内侧面上装有一个环状夹持器36,在轧制轧件时,它受到与其反向放置的轧件侧向板37向外(即朝着轧辊调节装置31的方向)的冲击;因此,它们使垂直轧辊9或盒29处于平衡状态。调节缸38给轧件侧向板37施加向后压向盒29的接触压力。
在更换万能轧机机座1的轧辊时,分别松开连接两个轧辊支架3、4的连杆39和水平轧辊7、8各自的拉紧杠15。然后用调节缸5拉动操作端轧辊支架4,使其离开轧辊支架3到达图1点划线所示的位置。此时,承载轴12、轴承13以及偏心轴套16连同蜗轮蜗杆传动装21(蜗杆19和蜗轮18)仍保持其各自固定的安装位置。此时,可以从内侧自由地接触到水平轧辊7、8的辊环14和带有垂直轧辊9的盒29。使用轧钢机上配有的室内起重机和一台合适的夹紧装置把辊环14从承载轴12的安装位置上拆下和/或把带有垂直轧辊9的盒29从其导向架23的盒形部分24的安装位置上拆下,然后换上新组装的盒或新辊环。一旦把操作侧的轧辊支架4重新拉回其工作位置并与对面的轧辊支架3相连接以及拉紧拉杆和水平轧辊7、8的承载轴11、12,则万能轧机机座1又做好了重新使用的准备。
