Abstract

本发明涉及一种飞剪,至少包括一个装有切刀的滚筒,该滚筒的圆周速度与轧制带材的推进速度同步,还包括一个位于所述滚筒对面的砧。本发明的任务是,提供一种以上所述类型的剪切装置,其磨损量小,并且制造公差较大时不会影响剪切效果。为此所建议的方案是,在所述砧辊(3)和切刀滚筒(2)之间的切刀滚筒(2)的工作位置上保留一个间隔(8),该间隔可保证由于轧制带材(4)上作用的纵向力使轧制带材(4)在薄弱位置处被断开。

Description

飞剪
技术领域
本发明涉及一种飞剪，至少包括一个装有切刀的滚筒，该滚筒的圆周速度与轧制带材的推进速度同步，还包括一个位于所述滚筒对面的砧。
背景技术
这种同步飞剪例如作为高速飞剪用于对轧制带材进行横切，它已公开在德国专利文献DE 19637862 A1中。其中或者使用两个相对设置并可相对调整的、两者装有切刀的滚筒，或者可以采用具有一个砧的滚筒，或者作为砧而使用。
调整路径的尺寸选择方式是，两个刀刃对置设置的滚筒以极小的距离相互重叠，或者一个切刀的剪切边位于对面滚筒的砧上，但是其圆周处在压力作用下。然而人们发现，这种剪切过程中的刀刃磨损以及和使用的砧的表面磨损极高，造成制造成本升高，而且切刀要能精确地靠在砧上，或者两个切刀要有确定的截面，所以飞剪必须在极窄的公差范围内制造，以保证良好的剪切效果。
发明内容
本发明的任务是，提供一种以上所述类型的剪切装置，其磨损量小，并且制造公差较大时不会影响剪切效果。
以上任务的解决方案体现在权利要求1的特征中。该方案可允许切刀仅部分地切入或楔入的轧制带材，大大限制切割部位的横截面，并且通过作用在轧制带材上的拉力实现分离。本发明的优点和其他有利的改进特征见从属权利要求。
附图说明
下面对照说明书附图所示实施例对本发明的详细特征作进一步的说明。
图1表示一个剪切装置，它包括一个切刀滚筒和一个砧辊，并且
图2表示一个剪切装置，用张紧的轧制带材作为砧。
优选实施例描述
在图1中表示出一个装有切刀1的切刀滚筒2，它的对面是一个光滑的作为砧使用的砧辊3。在朝箭头方向5转动的切刀滚筒和朝反方向6转动的砧辊之间运行着轧制带材4，其方向是箭头7。
在高速剪切装置中，切刀滚筒2通常位于轧制带材4的上方，其切刀并不接触轧制带材4。为进行切割要用图中未画出的调节装置使切刀滚筒2以相当于带材速度的圆周速度运转若干圈，并短促地朝砧辊3的方向进给，使切刀12切入轧制带材4，直到将带材分离到双箭头8所示的剩余厚度。
当带材低速运转时，可放弃采用调节装置，切刀滚筒2只需要在每个工作位置上进入相对砧辊3的固定间隔，并且在切刀滚筒2的近似一周旋转中，使圆周速度加速到带材线速度。
朝箭头7方向运行的轧制带材4此时将受到一个拉力的作用，其方式是，轧制带材在分离位置上，即被切刀1大大削弱的位置上断开。
该方案可使分离不采用纯粹的切割，而是仅通过切刀1切入或楔入轧制带材4的材料中，达到一定尺寸，使分离位置的强度被大大削弱。最终的分离所需的拉力可采用不同的方式施加。一种方案是该拉力由轧制带材4本身施加，但另一种可能是使切刀滚筒2的圆周速度稍小于或稍大于轧制带材4的进给速度7，使得轧制带材4被断开所需的拉力作用在切刀1和轧制带材4的始端或终端之间。还有一种可能性是，适当设计速度差和张力差，从而实现分离。
图2表示的是另一个实施例。其中的轧制带材4被一个卷曲机9所牵引。具有楔形10的刀辊11在杠杆臂12的端部转动，后者作为调整装置经一个连杆13与驱动偏心盘14相连。
进行切割时，偏心盘动作，经连杆13使杠杆臂12和刀辊11摆动到工作位置15上。
在该实施例中，放弃了专门的砧：在其工作位置15上，刀辊11使轧制带材向下弯曲，达到直线16以下，并且楔形10切入，通过刀辊接触轧制带材4的材料以及轧制带材受到偏转产生的力的作用使轧制带材4受到作用。通过轧制带材4的拉伸和/或刀辊的旋转，使楔形10部分切入轧制带材4后，在纵向力作用下产生分离。
本发明可作出一系列变化。例如调节装置可采用液压活塞驱动的杠杆，例如做直线运动的液压活塞。也可采用偏心装置，通过一个鱼尾板确定杠杆臂的摆角，或使其偏心盘直接引导杠杆臂。在任何情况下，不仅可以实现减小磨损的目的，而且剪切部件的加工也不需要很小的公差，所以简化了结构，提供了一种低磨损的剪切装置。
