摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method by which a double pipe having an outer pipe part which has high rigidity is manufactured even when a thin tubular material is used. SOLUTION: After forming a collar part 12 by expanding the lower end part of a tubular material 1, the lower end face of the collar part 12 is brought into contact with the contacting surface 21 of the collar part of a die 2 and a shaft material 4 is inserted into the main body part 13 by using the die 2 having the contacting surface 21 of the collar part with which the lower end part of the collar part 12 can be contacted and a die hole 24 which is formed into a shape in which at least a part of the inner peripheral surface 24c is expanded as it recedes from the contacting surface 21 of the collar part. By applying the pressure of liquid to the root part 12a of the collar part 12 connecting to the main body part 13 from the upper part in this state, the main body part 13 is turned so as to reverse the outer peripheral surface and the inner peripheral surface while expanding the main body part 13 successively from the end part and also the outer pipe part 14 having a shape matching the inner peripheral surface 24a of the die hole 24 is formed by pressing the turned part against the inner peripheral surface 24a of the die hole 24.

摘要： PROBLEM TO BE SOLVED: To provide a hydraulically bulged component provided with a flange having an arbitrary shape and size.
SOLUTION: This component is a hydraulically bulged component provided with the flange 2 which is outward projected and for joining other component and this hydraulically bulged component with the flange has a rib 31 on at least one side of the flange 2. It is preferable that the flange is formed by being squeezed after a portion of a material of which a bulged part is composed is bulged. Further, it is desirable that the rib is a thing for improving the strength and rigidity of the flange.

摘要： PROBLEM TO BE SOLVED: To provide a method for working a diametrically enlarged portion of a pipe by which the diametrically enlarged portion can be worked only by applying stress to the pipe from one end part, the reduction of the cost of equipment is possible by miniaturizing and simplifying the working apparatus and the diametrically enlarged portion in a position near the end part of the pipe and of a pipe bent beforehand is worked.
SOLUTION: By adding axial stress to the pipe 1 which is fast held with a clamp die 11 having a space for forming the diametrically enlarged portion from one end part with a punch die 13, applying fluid pressure to a position facing the space 27 for forming the diametrically enlarged portion of the pipe 1 from the inside through an injection port 29 of a liquid injecting shaft 12 provided on the punch die 13 and stretching a buckled part with the fluid pressure at the same time as a portion of the pipe 1 is buckled in the space 27 for forming the diametrically enlarged portion by the axial stress, the diametrically enlarged portion 1a which is suited to the shape of the space 27 for forming the diametrically enlarged portion is formed on the pipe 1.

摘要翻译：要解决的问题：为了提供一种用于直径扩大部分的直径扩大部分的加工方法，只要通过从一个端部向管道施加应力即可加工直径扩大部分，则设备成本的降低是可以通过在靠近管的端部的位置和预先弯曲的管的加工装置和径向扩大部分进行小型化和简化。
解决方案：通过向管1加上轴向应力，管1通过具有用于用冲头模13从一个端部形成直径扩大部分的空间的夹具11快速保持，将流体压力施加到面向空间的位置 27，用于通过设置在冲模13上的液体注入轴12的注射口29从内部形成管1的直径扩大部分，并且同时作为管的一部分拉伸具有流体压力的弯曲部分如图1所示，在轴向应力形成直径扩大部分的空间27中弯曲，在管1上形成适合用于形成直径扩大部分的空间27的形状的直径扩大部分1a。（C）2006，JPO＆NCIPI
