摘要： A flying shear is disclosed having upper and lower blade assemblies wherein upper and lower blade holders can be slid endwise out of the machine when replacing cutting blades and are rigidly clamped in position by adjustable tapered wedges acting against shoulders on the blade holder. The lower blade holder is mounted on a trapezoidal mounting member which has a small taper on both sides and is clamped between two oppositely tapered wedges in such a way that the gap between the cutting blades can be adjusted very easily while maintaining substantially perfect alignment of the blades by sliding the wedges lengthwise. Adjusting screws are provided to simplify this adjustment. Dovetail joints are provided between the side edges of the upper blade holder and its cooperating wedge and upper mounting member to prevent the upper blade holder from dropping out of its mounting member.
摘要翻译：公开了具有上下刀片组件的飞剪，其中上刀片保持器和下刀片保持器可以在更换切割刀片时从机器端部向外滑动，并且通过作用于刀片保持器上的肩部的可调节楔形楔紧固在适当位置。下刀架安装在梯形安装构件上，梯形安装构件在两侧具有小锥度并且被夹紧在两个相对锥形楔形件之间，使得可以非常容易地调节切割刀片之间的间隙，同时保持基本上完美的对准纵向滑动楔形刀片。提供调整螺丝以简化此调整。燕尾接头设置在上刀片支架的侧边缘及其配合的楔块和上安装件之间，以防止上刀架从其安装件脱出。
