    摘要： In the process of rolling a tubular billet with a mandrel is displaced in the rolling direction as it is simultaneously rotated about its longitudinal axis. Then a portion of the billet is advanced between the working rolls and is drawn over the mandrel during backward movement of the billet together with the mandrel. During forward movement of the billet with the mandrel, the billet is displaced relative to the mandrel in the same direction for a distance equal to that covered by the billet portion fed into the gap between the working rolls. The backward movement of the billet with the mandrel is effected at a speed substantially close to the peripheral speed of the working rolls at the starting moment of the drafting operation. The pilger mill comprises a stationary stand with continuously rotating working rolls. The mill also incorporates a billet feeding and turning mechanism and a billet gripping jaw kinematically linked with each other. The billet gripping jaw has screw nuts coaxially positioned therein and cooperating with a lead screw mounted together with the mandrel rod in a carriage. A tube turning mechanim has a tube gripping means accommodated in its body. Feeding and turning shafts in the billet feeding and turning mechanism are made hollow and formed with openings to receive respectively the lead screw and mandrel rod coaxially arranged therein.

    摘要翻译： 在轧制具有心轴的管坯的过程中，当其心轴沿着其纵向轴线同时旋转时，其在轧制方向上移位。 然后，坯料的一部分在工作辊之间前进，并且在坯料与心轴一起向后移动期间被拉过心轴。 在坯料与心轴的向前运动期间，坯料相对于心轴在相同方向上移动一定距离，该距离等于被供给到工作辊之间的间隙中的坯料部分所覆盖的距离。 坯料与心轴的向后运动在起草操作的起始时刻以基本上接近工作辊的圆周速度的速度进行。 包皮机包括具有连续旋转工作辊的固定架。 轧机还包括一个坯料进给和转动机构以及运动上相互连接的钢坯夹爪。 钢坯夹爪具有同轴地定位在其中的螺母，并与与芯棒一起安装在滑架中的导螺杆配合。 管转动机构具有容纳在其主体中的管夹持装置。 坯料进给和转动机构中的进给和转动轴被制成中空的并且形成有开口以分别容纳同轴地布置在其中的导螺杆和芯棒。

    摘要： THE RECOIL DEVICE OF A ROTARY FORGING MILL IS ENABLED TO OBTAIN UNI-DIRECTIONAL ROTATION OF THE HOLLOW, OR WORKPIECE, BETWEEN WORKING STROKES IN SUCH A MANNER THAT THE ANGLE OF ROTATION IS INDEPENDENT OF THE LENGTH OF STROKE OF THE RECOIL PISTON. THERE IS A SHAFT OPERATIVELY CONNECTED TO THE MANDREL HOLDER IN SUCH A WAL THAT ROTATION OF THE SHAFT IS TRANSMITTED TO THE MANDREL HOLDER. THE SHAFT IS ROTATED BY TWO PRESSURE-FLUID OPERATED PISTONS WHICH CAN BE COUPLED IN TURN TO THE SHAFT. THE PISTONS ARE ALSO COUPLED TO EACH OTHER SO THAT AS ONE PISTON MAKES A WORKING STROKE THE OTHER PISTON MAKES A RETURN STROKE.

    摘要： The state of the art discloses cold rolling mills comprising a roll stand, at least one roll rotatably mounted to the roll stand, a feed clamping saddle for feeding a blank, and a first drive for the feed clamping saddle. Those cold rolling mills have ball spindle drives with a high rate of wear as the drive for the feed clamping saddle. In comparison the object of the present invention is to provide a cold rolling mill whose drive for the feed clamping saddle involves no or only very slight wear and which in addition permits a slow movement of the feed clamping saddle. According to the invention that object is attained by a cold rolling mill which has a direct electromechanical linear drive for the feed clamping saddle.

    摘要翻译： 现有技术公开了一种冷轧机，其包括辊架，至少一个可旋转地安装在辊架上的辊，用于供给坯料的进给夹持鞍座和用于进给夹紧鞍座的第一驱动装置。 这些冷轧机具有作为进给夹紧鞍座的驱动器的高磨损率的球轴驱动。 相比之下，本发明的目的是提供一种冷轧机，其用于进给夹紧鞍座的驱动不涉及或仅仅非常轻微的磨损，并且还允许进给夹紧鞍座的缓慢移动。 根据本发明，目的是通过一种用于进给夹紧鞍座的直接机电线性驱动的冷轧机来实现的。
