查询词典 tilter

The device comprises: a conveyer belt; a let-off roller (16) on which the conveyer belt runs and from which the rubber tape is let off; a traverser (21) to move the let-off roller (16) in an X-axis direction parallel to the rotational axis of the object; a radial shifter to move the let-off roller in a Y-axis direction perpendicular to the X-axis direction; a tilter (23) to turn the rotational axis of the let-off roller (16) around a reference axis which is parallel to a Z-axis direction perpendicular to the X-axis direction and Y-axis direction.

所述装置包括：输送带；送出辊，所述输送带在送出辊上行进并且所述橡胶带从送出辊送出；移动台，其沿平行于物体的旋转轴线的X轴方向移动送出辊；径向移位装置，其沿垂直于X轴方向的Y轴方向移动送出辊；倾转装置，用于绕平行于Z轴方向的基准轴线转动送出辊的旋转轴线，所述Z轴方向垂直于X轴方向和Y轴方向。

Feed the gross pipe from front plant, cog down the upper roller to given size to rotating bring the pipe into rolling zone for reducing diameter and wall form rolling; after rolling from head to tail, turn 90Deg with the gross pipe, top bar and core head by tilter for next rolling travel that inverse roll to head to bring the pipe back to front plant; then, turn again for next periodical to-an-fro rolling till design size request.

将毛管自轧机前台喂入，将上轧辊压下至设定的尺寸，毛管在轧辊的旋转带动下曳入轧制区域，进行减径和减壁变形轧制；毛管从头部轧制到尾部后，将毛管、顶杆及芯头在翻转装置的作用下翻转90°，进行下一个轧制行程，反向轧制到头部，毛管回到轧机前台；再将毛管、顶杆及芯头在翻转装置的作用下翻转90°，进行下一个轧制周期往复轧制，轧制到毛管成达到设计尺寸要求。
