一种可横向矫正带材的在线对中装置和方法

本发明提供了一种可横向矫正带材的在线对中装置和带材对中方法，包括固定基座、螺纹副、操作侧对中矫正模块和传动侧对中矫正模块，丝杠固设在固定基座上，操作侧对中矫正模块和传动侧对中矫正模块结构相同且底端分别与操作侧螺母和传动侧螺母固定，操作侧螺母和传动侧螺母螺距相同旋向相反。本发明通过两个等螺距螺纹副使两个对中矫正模块同步地打开或者闭合，关于机组中心线始终处于对称位置的对中矫正模块通过短行程油缸驱动对中导轮以实现对带材的柔性横向调整。短行程油缸和高精度溢流阀的配合使用极大的提高了设备的可靠性并实现了对中设备的在线使用，兼具在线对中、在线横向矫正带材和离线对中的作用。 The invention provides an online centering device capable of transversely correcting a strip and a strip centering method.
