Description
図1は、本発明の一実施形態にかかる伝熱管拡管装置1の概略構成図である。
次に、伝熱管固定装置としての第1伝熱管クランプ装置103の詳細構造、及び、伝熱管拡管装置1の動作について、図1~図15を用いて説明する。ここで、図2、図6~図8及び図11~図15は、伝熱管拡管装置1の動作を示す図である。図3~図5、図9及び図10は、第1伝熱管クランプ装置103を構成するコレットチャック31を示す図である。
伝熱管固定装置としての第1伝熱管クランプ装置103の詳細構造について説明する。第1伝熱管クランプ装置103は、主として、掴持部37aを有する複数のコレットチャック31と、移動部としてのコレット開閉用スライド板32と、移動部駆動装置としてのコレット開閉用シリンダ33とを有している。
伝熱管拡管装置1の動作について説明する。
本実施形態の伝熱管拡管装置1及び伝熱管拡管方法には、以下のような特徴がある。
ここでは、上記のように、移動部としてのコレット開閉用スライド板32がコレットチャック31の掴持部37aの周囲を覆った第1状態の状態でマンドレル51による拡管が行われる。このため、伝熱管203の外面が掴持部37aの内面に当接し、そして、掴持部37aの外面がコレット開閉用スライド板32の内面に当接することになる。すなわち、掴持部37aが伝熱管203を軸方向に動かないように固定する際に、コレット開閉用スライド板32が伝熱管203の一端部203aを掴持する掴持部37aに重なった状態になる。これにより、ここでは、従来の管当接部材及びガイド筒による伝熱管の固定に比べて、掴持部37aによって伝熱管203を掴持する力のバラツキが抑えられ、精度のよい拡管を行うことができる。また、ここでは、従来の管当接部材及びガイド筒による伝熱管の固定に比べて、掴持部37aによって伝熱管203を掴持する力自体も大きくすることができる。このため、伝熱管203の軸方向の一端部203aのうち掴持部37aによって掴持される部分の軸方向長さを短くすること、ひいては、伝熱管203の軸方向の一端部203aの軸方向長さを短くすることが可能になる。そして、これにより、熱交換器201のコンパクト化にも寄与することができる。しかも、ここでは、コレット開閉用スライド板32を伝熱管203の軸方向に移動させるだけで掴持部37aの周囲を覆う第1状態に切り換えることができるため、伝熱管203の間隔が狭い場合にも適用することができる。さらに、ここでは、従来のガイド筒の移動工程を伴う拡管とは異なり、伝熱管203を軸方向に動かないように固定するとともに、拡管工程を一気に行うことができるため、拡管をスムーズに行うことができる。
また、従来の管当接部材及びガイド筒による伝熱管の固定では、伝熱管の本数と同じ個数のガイド筒の移動が必要になる。これに対して、ここでは、上記のように、移動部としてのコレット開閉用スライド板32が1つあり、このコレット開閉用スライド板32が複数のコレットチャック31の掴持部37aのすべてに対応している。これにより、1つのコレット開閉用スライド板32を第1状態に切り換えるだけで、複数の掴持部37aのすべてで伝熱管203の固定を行うことができる。これにより、従来の管当接部材及びガイド筒による伝熱管の固定では対応が困難な伝熱管203の間隔が非常に狭い場合や伝熱管203の間隔が等間隔ではない不等ピッチの場合にも対応可能になり、種々の仕様の熱交換器201の拡管を行うことができる。
また、ここでは、上記のように、移動部としてのコレット開閉用スライド板32が第1状態になる際に、コレットチャック31の掴持部37aの内面が伝熱管203の軸方向に平行になる。これにより、コレット開閉用スライド板32が第1状態に切り換えられた状態において、掴持部37aの内径d3を所定の寸法、すなわち、拡管前の伝熱管203の軸方向の一端部203aの外径よりも大きく、かつ、拡管後の伝熱管203の軸方向の一端部203aの外径よりもわずかに小さい寸法にすることができる。これにより、伝熱管203の拡管時に伝熱管203の外面を掴持部37aの内面に確実に当接させることができる。
また、ここでは、上記のように、コレットチャック31の掴持部37aが、移動部としてのコレット開閉用スライド板32が第2状態にある状態で、放射状に開くように形成されている。これにより、伝熱管203を拡管して掴持部37aが伝熱管203を軸方向に動かないように固定するとともに伝熱フィン202と伝熱管203とを固定した後に、コレット開閉用スライド板32を第1状態から第2状態に切り換えることによって、掴持部37aが伝熱管203を固定した状態を解除することができる。また、掴持部37aが伝熱管203を固定した状態を解除した後に、掴持部37aの内面と伝熱管203の外面との間の隙間を利用して、伝熱管203の軸方向の一端部203aにフレア加工を行うことができる。
また、ここでは、上記のように、コレットチャック31の掴持部37aの内面が平滑面である。これにより、掴持部37aに掴持される伝熱管203の一端部203aにおいて、拡管後の肉厚を均等に保つことができる。
また、ここでは、上記のように、コレットチャック31の掴持部37aの先端側には、先広がりのテーパ(ここでは、第1案内部37dのテーパ状の内面)が形成されている。これにより、伝熱管203の一端部203aに掴持部37aを配置する際に、伝熱管203の一端部203aを掴持部37aにスムーズに案内することができる。
また、ここでは、上記のように、コレットチャック31の掴持部37aの基端側の外面には、移動部としてのコレット開閉用スライド板32が第2状態から第1状態に切り換わる際に、コレット開閉用スライド板32を案内するテーパ(ここでは、第2案内部37eのテーパ状の外面)が形成されている。これにより、コレット開閉用スライド板32を第2状態から第1状態に切り換える動作をスムーズに行うことができる。
<A>
上記実施形態の伝熱管拡管装置1においては、コレットチャック31の掴持部37aの内面が平滑面であったが(図4参照)、例えば、図16に示すように、凹凸面であってもよい。この場合には、掴持部37aに掴持される伝熱管203の一端部203aにおいて、拡管時の管肉の逃げ代を確保することができる。
また、上記実施形態の伝熱管拡管装置1においては、各種装置の駆動装置がサーボモータやシリンダであったが、これに限定されるものではない。
また、上記実施形態の伝熱管拡管装置1においては、伝熱管203の軸方向が上下方向を向く縦型の構成であったが(図1参照)、これに限定されるものではなく、伝熱管203の軸方向が横方向を向く横型の構成であってもよい。
また、上記実施形態の伝熱管拡管装置1においては、拡管のための装置102~105だけでなく、フレア加工を行うためのフレア装置106も有する構成であったが(図1、図14及び図15参照)、これに限定されるものではなく、拡管のための装置102~105だけであってもよい。
