場合に使用する熱溶着装置に関するものである。
〈従来技術〉 従来、プラスチツク部品の溶着による成形かし
めは、かしめ部成形のための予熱、加熱及び加
圧、離形のための冷却の加工順序で行なわれる。
第２図に示すように従来のプラスチツク部品２は
被かしめ部材１の透孔１ａに対して突起部２ａを
形成し、これを挿入した後に、先端に半球状の凹
部３ａを有する鏝先３を接触させ、ヒータ４で加
熱すると同時に加圧することにより、前記突出部
２ａを溶かし、半球状の成形かしめ部５を形成

合するものであつた。
上記のような、半円球状の成形かしめ部では、
実際に力が加わる外周より幅Ａの区間が、周縁部
に向つて肉厚が薄くなるように形成されているた
め、かしめ強度が弱い欠点があつた。また溶着時
の圧力の掛け具合により、上記成形かしめ部の直
径が小さくなることもあり注意を必要とするもの
であつた。
〈目的〉 本考案は上記欠点を除去するものであり、成形
かしめ部の周縁部の肉厚を厚くし、そのかしめ強

供するものである。
〈実施例〉 以下、本考案の一実施例を図面に従つて説明す
ると、第１図において、６は熱溶着装置の鏝先で
あり、その先端部には半球状の凹部６ａとその周
囲に段部６ｂを形成しているものである。
上記の鏝先６に変更することにより、ヒータ４
で溶かされる突出部２ａは前記凹部６ａと段部６
ｂとにより、周縁部の肉厚を厚くしたかしめ部７
が形成されるため、幅Ｂの間での肉厚があまり変
化なく、且つその容積を大きくすることができる
ため、その強度を大幅に向上させることができ

圧力のばらつきに余裕ができ、かしめ強度を略一
定のものにすることができるものである。
〈効果〉 以上のように、本考案の熱溶着装置では、先端
に半球状の凹部と、この凹部をとり囲む段部とを
形成した鏝先を有してなり、プラスチツク部にお
けるかしめ部周囲を肉厚にすることができるの
で、その容積を増やすことができるとともにかし
め強度を向上させることができるものである。
