＜触媒コンバータケースの製造装置１００の動作＞
次に、触媒コンバータケースの製造装置１００の動作について説明する。図１（ａ）に示すように、触媒コンバータケースの製造装置１００内に素管１を装着してから、アクチュエータ８０を作動させると、図１（ｂ）に示すような触媒コンバータケース１０が製造される。すなわち、触媒コンバータケースの製造装置１００によれば、アクチュエータ８０を作動させるという１回の工程により、素管１に縮管部１０ａと拡管部１０ｂを隣接して形成することが可能となり、触媒コンバータケース１０を製造することができる。
<Operation of Catalytic Converter Case Manufacturing Apparatus 100>
Next, the operation of the catalytic converter case manufacturing apparatus 100 will be described. As shown in FIG. 1A, when the raw tube 1 is mounted in the catalytic converter case manufacturing apparatus 100 and then the actuator 80 is operated, the catalytic converter case 10 as shown in FIG. 1B is manufactured. Is done. That is, according to the catalytic converter case manufacturing apparatus 100, the contracted tube portion 10a and the expanded tube portion 10b can be formed adjacent to the base tube 1 by a single step of operating the actuator 80, and the catalytic converter can be formed. Case 10 can be manufactured.
具体的には、図１（ａ）に示すように、縮管用のダイ部材３０及び拡管用のダイ部材４０によって素管１を位置決め固定してから、アクチュエータ８０を作動させる。このアクチュエータ８０の作動により、連結部材７０は、軸芯２に沿って枠体２０の他端面２２側（図１の場合には上方側。以下同じ。）に移動する。この連結部材７０の移動に伴って、縮管用の当接部材５０及び拡管用の当接部材６０は、同時に上方側に移動する。 Specifically, as shown in FIG. 1 (a), the element tube 1 is positioned and fixed by the die member 30 for contraction and the die member 40 for tube expansion, and then the actuator 80 is operated. By the operation of the actuator 80, the connecting member 70 moves along the axis 2 toward the other end face 22 side of the frame body 20 (upper side in the case of FIG. 1, the same applies hereinafter). Along with the movement of the connecting member 70, the contact member 50 for contraction and the contact member 60 for tube expansion simultaneously move upward.
縮管用の当接部材５０が上方側に移動すると、縮管用のダイ部材３０は、軸芯２に向かって移動する。そうすると、素管１の外周面１ａは、縮管用のダイ部材３０の内周面３０ａと当接しつつ軸芯２に向かって半径方向に押圧されて縮径される。これにより、素管１には、縮管部１０ａ（図１（ｂ）参照）が形成されることとなる。 When the contracting tube contact member 50 moves upward, the contracting tube die member 30 moves toward the shaft core 2. If it does so, the outer peripheral surface 1a of the raw pipe | tube 1 will be pressed by the radial direction toward the shaft core 2 and diameter-reduced, contacting the inner peripheral surface 30a of the die member 30 for tube contraction. As a result, a contracted tube portion 10 a (see FIG. 1B) is formed in the raw tube 1.
これと同時に、拡管用の当接部材６０も上方側に移動し、この移動に伴って、拡管用のダイ部材４０は、軸芯２から離れるように移動する。素管１の内周面１ｂは、拡管用のダイ部材４０の外周面４０ａと当接しつつ、軸芯２から離れるように半径方向に押圧されて拡径される。これにより、素管１には、拡管部１０ｂが形成されることとなる。 At the same time, the abutting member 60 for pipe expansion also moves upward, and the die member 40 for pipe expansion moves away from the shaft core 2 along with this movement. The inner peripheral surface 1b of the raw tube 1 is pressed in the radial direction so as to be separated from the shaft core 2 while being in contact with the outer peripheral surface 40a of the die member 40 for tube expansion. As a result, the expanded portion 10b is formed in the raw tube 1.
このようにして素管１に縮管部１０ａ及び拡管部１０ｂが形成されると、触媒コンバータケース１０が製造される。なお、製造された触媒コンバータケース１０を触媒コンバータケースの製造装置１００から取り出すには、まず、アクチュエータ８０を作動させて連結部材７０を下方側に移動させる。これにより、縮管用の当接部材５０及び拡管用の当接部材６０は、いずれも下方側に移動する。次に、縮管用のダイ部材３０を軸芯２から離れるように半径方向に移動させるとともに、拡管用のダイ部材４０を軸芯２に向かって半径方向に移動させる。このようにして、触媒コンバータケース１０の位置決め固定を解除するとともに、開口部２１ａから枠体２０の外側に、触媒コンバータケース１０を取り出すことが可能となる。 In this way, when the contracted tube portion 10a and the expanded tube portion 10b are formed in the raw tube 1, the catalytic converter case 10 is manufactured. In order to take out the manufactured catalytic converter case 10 from the catalytic converter case manufacturing apparatus 100, first, the actuator 80 is operated to move the connecting member 70 downward. As a result, both the contraction tube contact member 50 and the tube expansion contact member 60 move downward. Next, the die member 30 for contraction is moved in the radial direction so as to be separated from the shaft core 2, and the die member 40 for tube expansion is moved in the radial direction toward the shaft core 2. In this manner, the positioning and fixing of the catalytic converter case 10 can be released, and the catalytic converter case 10 can be taken out of the frame 20 from the opening 21a.
＝＝＝第二実施形態＝＝＝
次に、図２を参照しながら、本発明の第二実施形態に係る触媒コンバータケースの製造装置２００について説明する。図２において、図１と同一の箇所には同一の符号を付すこととし、異なる箇所を中心に説明する。
=== Second Embodiment ===
Next, a catalytic converter case manufacturing apparatus 200 according to a second embodiment of the present invention will be described with reference to FIG. In FIG. 2, the same parts as those in FIG. 1 are denoted by the same reference numerals, and different parts will be mainly described.
図２に示す触媒コンバータケースの製造装置２００は、図１に示した触媒コンバータケースの製造装置１００を改良したものであり、これとほぼ同様の構成を有する。但し、同図に示す触媒コンバータケースの製造装置２００においては、貫通孔２３ａ、ロッド５１、及び台座９１の構成が、図１に示したものと異なる。すなわち、貫通孔２３ａは、枠体２０の他端面２２ではなく、枠体２０の側部２３に設けられている。また、ロッド５１は、この貫通孔２３ａを挿通して縮管用の当接部材５０に連結されるように構成されており、棒状の構成ではなく、折り曲げられて構成されている。さらに、台座９１の内面と枠体２０の側部の外面との間には、空隙が設けられており、この空隙により、ロッド５１が上下に移動可能となるような可動域が確保されている。 A catalytic converter case manufacturing apparatus 200 shown in FIG. 2 is an improvement of the catalytic converter case manufacturing apparatus 100 shown in FIG. 1, and has a configuration substantially similar to this. However, in the catalytic converter case manufacturing apparatus 200 shown in the figure, the configurations of the through hole 23a, the rod 51, and the base 91 are different from those shown in FIG. That is, the through hole 23 a is provided not on the other end surface 22 of the frame body 20 but on the side portion 23 of the frame body 20. The rod 51 is configured to be inserted through the through hole 23a and connected to the contact member 50 for contraction, and is not a rod-shaped configuration but is bent. Further, a gap is provided between the inner surface of the pedestal 91 and the outer surface of the side portion of the frame 20, and a movable range is secured by this gap so that the rod 51 can move up and down. .
このような構成とした場合にも、触媒コンバータケースの製造装置２００は、図１とほぼ同様の動作を行うこととなり、アクチュエータ８０を作動させるという１回の工程により、素管１に縮管部１０ａと拡管部１０ｂとを隣接して形成し、触媒コンバータケース１０を製造することが可能となる。 Even in such a configuration, the catalytic converter case manufacturing apparatus 200 performs substantially the same operation as in FIG. 1, and the contracted tube portion is formed on the raw tube 1 by a single process of operating the actuator 80. 10a and the expanded pipe portion 10b are formed adjacent to each other, and the catalytic converter case 10 can be manufactured.
