Description
При повороте подающей клети на угол а перемещение заготовки S, создаваемое клетью , будет направлено под углом а к продольной оси стана и может быть разложеноWhen turning the feed stand at an angle a, the movement of the workpiece S created by the cage will be directed at an angle a to the longitudinal axis of the mill and can be decomposed

5non 5-Sina. Составл юща перемещени 5прод направлена вдоль оси стана и представл ет собой поступательное перемещение заготовки . Составл юща 5поп представл ет поворот заготовки вокруг продольной оси стана , который приводит к изменению взаимного полол :ени полуобечаек и к изменению рассто ний между кромками в обоих стыках трубы. Нижн заготовка при повороте подающей клети поворачиваетс в направлении, противоположном смещению верхней заготовки .5non 5-sina. The movement component 5prod is directed along the mill axis and is a translational movement of the workpiece. The component 5pop represents the rotation of the workpiece around the longitudinal axis of the mill, which leads to a change in the mutual field: half of the half-shells and to a change in the distance between the edges in both joints of the pipe. The bottom billet is rotated in the opposite direction to the displacement of the top billet when the feed stand turns.
На фиг. 2 стрелками показаны направлени вращени заготовок при повороте подающей клети на угол („ как показано на фиг. 3.FIG. 2, the arrows indicate the directions of rotation of the blanks when the feed stand is rotated through an angle (as shown in Fig. 3.
