る。However, in the pipe expanding apparatus having the above-mentioned structure, various devices such as a limit switch 10, a rack body 11, and an encoder 13 using a pinion gear 12 meshing with the rack body 11 must be individually attached to the apparatus. As a result, the production cost rises.
【００１１】よって、前記の如く製造コストが高騰する
のを抑えるために、図３に示す構造を有した拡管装置が
開発されて前記拡管装置に代わって市場に出回りつつあ
る。Therefore, in order to suppress the increase in the manufacturing cost as described above, a tube expanding device having the structure shown in FIG. 3 has been developed and is being marketed in place of the tube expanding device.

成にしてなるものである。The expansion device uses a cylinder 4 equipped with a pulse encoder 18 and attaches a reference base 1 for stopping the lowering of a stripper plate 9 to a telescopic rod 4a of the cylinder 4 via a fixing member 1a such as a male screw. The configuration is as follows.

【００１５】[0015]
【発明が解決しようとする課題】しかしながら、上記構
成からなる拡管装置に於いては、下記の様な問題点があ
った。However, the pipe expanding device having the above-described structure has the following problems.
【００１６】即ち、上記前者及び後者何れの構成であっ
ても、ストリッパプレート９は、該ストリッパプレート
９の両端を支持する一対のシリンダのみを介して所定箇
所に停止するものである。That is, in either of the former and the latter configurations, the stripper plate 9 stops at a predetermined position only through a pair of cylinders supporting both ends of the stripper plate 9.
【００１７】よって、拡管時に往復作動体７と共に下降
するストリッパプレート９を所定箇所で停止させる際、
常にシリンダの伸縮ロッドのみがストリッパプレート９
の自重を、該伸縮ロッドに設けられた基準台１を介して
ダイレクトに受けることになる。Therefore, when the stripper plate 9 descending with the reciprocating member 7 at the time of expanding the pipe is stopped at a predetermined position,
Always only the telescopic rod of the cylinder is stripper plate 9
Is directly received via the reference base 1 provided on the telescopic rod.
【００１８】よって、シリンダの伸縮ロッドのみでスト
リッパプレート９の自重を受けた場合において、伸縮ロ
ッドの伸出長がある一定寸法を超えた場合には、該伸縮
ロッドに瞬間的な撓みが生じることとなり、かかる撓み
の大きさは伸縮ロッドの伸出長に比例して増すことにな
る。Therefore, when the extension length of the extensible rod exceeds a certain dimension when the stripper plate 9 receives its own weight only by the extensible rod of the cylinder, instantaneous bending occurs in the extensible rod. Thus, the magnitude of the deflection increases in proportion to the extension length of the telescopic rod.
【００１９】従って、特に全長の長い熱交換器１５を装
置本体１４ａの基台１９にセットして拡管する際、伸縮
ロッドは最大長域でシリンダより伸出することとなり、
その結果、シリンダから最大長域で伸出した状態の伸縮
ロッドがストリッパプレート９の自重を受けた瞬間に、
伸縮ロッドが大きく撓んでシリンダのシール部を破損す
るという恐れがあった。Therefore, particularly when the heat exchanger 15 having a long length is set on the base 19 of the apparatus main body 14a and expanded, the telescopic rod extends from the cylinder in the maximum length range.
As a result, at the moment when the telescopic rod extended from the cylinder in the maximum length region receives the weight of the stripper plate 9,
There is a risk that the telescopic rod will bend significantly and damage the seal portion of the cylinder.

う恐れもあった。Also, for example, instead of the cylinder, a base 19
When the reference table 1 is reciprocated using a reciprocating means such as a bar-shaped male screw (not shown) provided on the base 1, when the weight of the stripper plate 9 is received by the reference table 1, There was also a risk that the screws would bend too much and break the screw threads as before.

スト面での問題もあった。Further, as described above, the heat exchanger 15 having a long overall length is used.
When expanding the telescopic rod, the extension length of the telescopic rod is naturally limited. Therefore, particularly when expanding the heat exchanger 15 having a long overall length, replace the cylinder with the telescopic rod having an applicable effective stroke. Therefore, not only is the replacement work complicated, but also there is a problem in terms of cost that a cylinder corresponding to the entire length of the heat exchanger 15 must be prepared.

供するものである。According to the present invention, even when the telescopic rod of the cylinder, the rod-shaped male screw, or the like, which is the reciprocating means of the reference base, momentarily receives the weight of the stripper plate via the reference base, The first problem is to reduce the deflection of the rod-shaped male screw by supporting the reference table at a plurality of positions to prevent the seal portion of the cylinder from being damaged. Even if there is no need to prepare or replace a cylinder adapted to the entire length of the heat exchanger 15, the second problem is to move the reference base 1 to adapt to the entire length of the heat exchanger 15. A reference platform is provided.
