Description

【発明の詳細な説明】 〔産業上の利用分舒〕 本発明は、複数の熱可塑性合成樹脂成形物を迅速に且つ
強力に溶着する方法に関する。
〔関連技術とその問題点〕
一般に、複数の合成樹脂成形物を接続するにはモルタル
、接着剤等を用いた接着手段がとられている。しかし、
それは接続作業の能率面。
接続強度面並びに合成樹脂成形物の接続部に複雑な接続
構造を形成するための成形面等に問題を有しているとと
もに、接続作業がしにくい場合も多かった。
ところで、この問題を解決するものとして高周波加熱手
段を用いる事が考えられる。しかし、高周波誘電加熱を
行なった場合、温度分布が均一にならないため複数の合
成樹脂成形物の中部が加熱されて軟化しても表面部分が
硬くて溶着出来ないという問題があり、特に高周波誘電
加熱の場合、合成樹脂成形物を全体的に加熱するため局
部加熱により溶着を行うにはエネルギー損失が大である
。
〔発明の目的〕
本発明の目的とするところは、高周波加熱手段を用いて
上記問題を解消しながら合成樹脂成形物を溶着する方法
を提供することにある。
〔発明の概要〕
本発明の複数の合成樹脂成形物を溶着する方法は溶着す
べき複数の熱可塑性合成樹脂成形物間に金属体を設け、
この金属体を高周波誘導加熱により急速に加熱した後、
熱可塑性合成樹脂成形物同志を溶着するものである。
〔実施例〕
第１図において、１．２は溶着すべき複数の熱可塑性合
成樹脂成形物、３はその合成樹脂成形物１，２の溶着部
分Ｇこ介在したリング状の金属体、４は金属体加熱用の
高周波誘導コイルである。
しかして、複数の熱可塑性合成樹脂成形物１゜２の溶着
接合部分間にリング状金属体３を置き、その金属体３が
ほぼ中心軸線位置に在るように高周波誘導加熱コイル４
を設けて、この加熱コイル４に高周波大電流を短時間通
電する。すると、金属体３の表層部には金属体３の比抵
抗の平方根に比例し、かつ実効透磁率と印加周波数との
平方根に反比例した深さの加熱層が得られる。そこで表

着する。実験によると、加熱温度９０〜１２０℃で数秒
間の後衝撃等に対して良好な溶着が出来た。その場合、
金属体３はＦｅ分の多い金属が好ましく、第３図のよう
なプレートリング状のもの、第４図のようなパンチング
プレート状のもの等適宜選定してもよい。また、第５図
のように合成樹脂成形物１，２の少なくとも一方に溝等
の金属体３の位置決め部５を形成することが好ましい。
合成樹脂成形物１，２は同質材あるいは異質材でもよい
ことは勿論であり、少なくとも一方が長尺物であっても
溶着が可能である。金属体３を高周波誘導加熱によって
加熱すると、金属体３はその中心部は加熱されず、表層
部より非常に低温であるため溶着後直ちに冷却されるこ
とになり、溶着時間が短かく、合成樹脂成形物の形層れ
や寸法精度が防止される。
また、第２図のように複数の合成樹脂成形物１゜２の溶
着部には金属体３が埋入するから剪断応力、耐衝撃力も
大となる。
〔発明の効果〕
本発明は溶着すべき複数の熱可塑性合成樹脂成形物間に
金属体を設け、この金属体を高周波誘導加熱により急速
に加熱した後、熱可塑性合成樹脂成形同志を溶着するも
のであるから、迅速且つ強力に溶着出来るとともに、金
属体が埋入した溶着部の断面構造になって耐衝撃力、剪
断応力も大となり、接着作業が行いにくい箇所をも容易
に高周波加熱出来、その効果は大きい。
