摘要： In a method and apparatus for manufacturing a corrugated tube, a tube is clamped by a pair of spaced apart chucks. A local portion of the tube is softened. The chucks are moved in the same direction such that the trailing or rearward chuck moves farther than the leading or forward chuck, thereby imparting an axially compressive force on the tube. Accordingly, a bulge is formed at the softened portion of the tube. The heating and compression cycle may be performed several times to obtain a corrugated tube having a plurality of bulges or waves formed therein.

摘要： The present invention can provide a method and an apparatus for bending a pipe whose bending cross section has reduced compressed ratio, reduced reduction ratio of area and reduced reduction in thickness and in which bending can be conducted at the desired curvature. In the present invention, both edges of the pipe bending portion are arrested and grasped, a center of one bending edge is set to be the axis and a revolution axis is amounted on it, a rotation axis is mounted at a center of the other bending edge and gears are installed on the revolution axis and the rotation axis so as to engage each other so that the driving is driven to the gear on the rotation axis. The rotation axis revolves having the radius to be the distance from the rotation axis to the revolution axis and at the same time the rotation axis rotates on its axis having the radius of the gear in response to the revolution angle. Accordingly, both of the rotational centers of rotation and revolution are existed on the pipe axis and the bending stress is effected on the whole of the bending portion. Therefore, the levels of the tensile force at the bending outside and the compressive force at the bending inside are constantly kept to be a balanced condition. As the result, the problems that the thickness of the pipe bending portion is reduced and that the pipe bending portion is compressed are improved very much.
摘要翻译：本发明可以提供一种用于弯曲管道的方法和装置，其弯曲横截面具有减小的压缩比，减小的面积减小率和减小的厚度减小，并且可以以期望的曲率进行弯曲。在本发明中，管弯曲部的两个边缘被抓住，一个弯曲边缘的中心被设定为轴线并且在其上形成转轴，旋转轴安装在另一个弯曲的中心边缘和齿轮安装在旋转轴线和旋转轴线上以便彼此接合，使得驱动被驱动到旋转轴上的齿轮。旋转轴以半径为旋转轴向旋转轴的距离旋转，同时旋转轴在其具有相应于转角的齿轮半径的轴上旋转。因此，旋转旋转中心和旋转中心都存在于管轴上，并且在整个弯曲部分上产生弯曲应力。因此，弯曲外侧的拉伸力和弯曲内侧的压缩力的水平恒定地保持为平衡状态。结果，管弯曲部的厚度减小，管弯曲部被压缩的问题变得非常大。

摘要： Provided are a steel having a non-magnetic portion, which can be applied to the steel of the remaining portion irrespective of the material and which has a structure of a short treating time required and a determined depth direction, its manufacturing method, and a revolving electric core. There is prepared an electromagnetic steel sheet having a recessed groove. A two-layered chip of a modifier metal foil and a stainless steel foil is so set in the groove of the electromagnetic steel sheet that the electromagnetic steel sheet and the stainless steel foil have surfaces of the same height. The modifier metal foil is melted when electric current is applied under pressure. When this pressing and current applying is continued, inner sides of the electromagnetic steel sheet and the stainless steel foil contacting the modifier metal foil are melted to form a nonmagnetic alloy layer in the region excepting the surface portions of an electromagnetic steel sheet layer and a stainless steel layer. The nonmagnetic alloy layer and the stainless steel layer do not pass a magnetic flux.
