The purpose is to provide a jig useful for fixing the ring in a predetermined position by friction and shearing by plastically deforming the end portion of the tube into which the ring is inserted outward with an expanding force from within. At the point.

度を出し易い技術をもって固着できる利点がある。A method for manufacturing a pipe joint in which a joint pipe and a ring are manufactured separately, and the ring is inserted into the joint pipe to secure them together, is compared to a method in which the joint pipe and ring are integrally manufactured by casting or machining. The method has the advantage that the position of the ring can be freely selected and various types of pipe joints with rings can be manufactured at low cost. There are disadvantages to the method of fixing the ring to the pipe by welding, namely, a decrease in the engagement force between the ring and the housing due to irregularly shaped beads formed on the side surface of the ring, and anti-corrosion treatment of the inner surface of the pipe due to heating. There is no deterioration or destruction of the lining treatment such as anti-corrosion treatment, and it has the advantage that it can be fixed using a technique that is simpler and more accurate than welding such as pipe expansion.

とを特徴とするものである。The joint pipe processing jig with a metal ring according to the present invention is used when a method with such advantages is adopted, and the metal ring for pipe jointing is attached to the outer peripheral surface near the end of the joint pipe. When fixing, the jig is used by being fitted on the outside of the pipe, and has an inner diameter that is smaller than the outside diameter of the joint pipe, and has a jig that is inserted into the outside of the joint pipe on its inner circumferential surface. It should have a concave circumferential groove that fits into the fitted metal ring, and be constructed to have a strength that can withstand the tube expansion force that plastically deforms the tube portion corresponding to the insertion position of the ring outward. It is characterized by:
即ち、拡管力は、管のみならず、管に挿入位置させたリ
ングにも作用する。That is, the tube expansion force acts not only on the tube but also on the ring inserted into the tube.
従って、例えば、拡管力のみを作用させてリングを管に
固着する場合には、拡管力によるリングの変形を防止し
て摩擦と剪断とによる固着力を確保するために、リング
を管よりも変形に強い材質、形状にするといったように
リング構成に制約を受ける。Therefore, for example, when fixing a ring to a pipe by applying only the tube expansion force, the ring must be deformed more than the tube in order to prevent the ring from deforming due to the tube expansion force and to ensure the fixation force due to friction and shear. There are restrictions on the ring configuration, such as the use of materials and shapes that are resistant to corrosion.
然し乍ら、本考案によれば、治具を装着しておくことに

態に構成し得るに至ったのである。However, according to the present invention, by attaching the jig, deformation of the ring against the tube expansion force can be reliably prevented regardless of its material strength, and only the tube can be deformed. Both the ring and the tube can be made of materials that suit the conditions of use, and this allows the method of effectively fixing the ring to the tube by expanding the tube to ensure the desired ring-attached joint tube. Moreover, it has now been possible to configure it in a high quality state.
