摘要： In the case of bending an outer pipe, a pressure die provided just in front of a bending section is provided with a groove, wherein the shape of the groove on the side far from the bending section is semi-circular and of which the diameter corresponds to that of the outer pipe before bending, while the shape of the groove on the side near the bending section is tapered semi-elliptically. With this, the cross-sectional shape of the outer pipe is caused to change into a substantially elliptical shape in which the outside of the section to be bent is tapered. The cross-sectional shape becomes substantially circular when bending is completed.

摘要： A method and an apparatus for bending pipes by clamping one end of the pipe between a formed roll and a rotary base and by turning the rotary base so that the pipe may be bent along the outer periphery of the formed roll. A mandrel supported by a mandrel bar is arranged inside the pipe at a position corresponding to a position slightly behind where the pipe is clamped between the formed roll and the rotary base. The rear end of the mandrel bar is held in place by a pressurizing device so that the mandrel can be held fixed at said predetermined position inside the pipe. At the same time, a vibrating device attached to the mandrel bar causes the mandrel to continuously reciprocate in the axial direction of said mandrel bar, whereby flattening of the pipe which occurs when the pipe is bent along the outer periphery of the formed roll can be corrected by the reciprocation of the mandrel. As a result, the radius of curvature R of the pipe can be made smaller than R=3D, where D is the diameter of the pipe.
摘要翻译：一种用于通过将管道的一端夹持在成形辊和旋转底座之间并通过转动旋转底座使得管可沿着成形辊的外周弯曲来弯曲管道的方法和装置。由芯棒支撑的心轴配置在管道内部的位置，该位置对应于管道夹在形成的辊和旋转底座之间稍稍后方的位置。芯棒的后端通过加压装置保持就位，使得心轴可以保持固定在管内的所述预定位置。同时，安装在芯棒上的振动装置使心轴沿着所述芯棒的轴向连续地往复运动，由此当管沿成形辊的外周弯曲时发生的管的扁平化可以是通过心轴的往复运动校正。结果，管的曲率半径R可以小于R = 3D，其中D是管的直径。
