Zusammenfassung: | To provide a caulking device that prevents a work from being damaged when a tip of a punch comes close to the work, and a method for manufacturing a molded product by caulking.SOLUTION: A thermal caulking device 20 includes: a flame 23; a punch holder 26 that can move up and down with respect to the frame; a punch 10 attached to the punch holder 26 and having a pressing part 17 at its tip capable of pressing a convex part of a fixing member; and a work upper surface stopper 40 mechanically coupled with a punch holder extension 27 extending from holder body 261 of the punch holder 26. The work upper surface stopper 40 has an inner wall facing a tip of the punch 10 through a gap and has a contact surface 48 that can contact the upper surface of the convex part protruding side of a fixed object and that prevents an occurrence of damage to the fixed object when the pressing part 17 approaches the upper surface. As a result, the punch does not bite into the work without being affected by the dimensions of the work.SELECTED DRAWING: Figure 1
【課題】 ワークとパンチ先端との接近に伴うワークの損傷の発生を防止するかしめ装置及びかしめ固定による成形品の製造方法を提供する。【解決手段】 熱かしめ装置20は、フレーム23と、フレームに対し、上下動可能なパンチホルダ26と、パンチホルダ26に取り付けられ、先端に固定部材の凸部を押圧可能な押圧部17を有するパンチ10と、パンチホルダ26のホルダ本体261から延びるパンチホルダ延長部27と機械的に結合されるワーク上面ストッパ40を備える。ワーク上面ストッパ40は、パンチ10の先端に隙間を介して対向する内壁を有し、被固定物の凸部の突き出す側の上面に当接可能な当接面であって押圧部17が前記上面に接近するとき被固定物の損傷発生を防止する当接面48を有する。これにより、ワークの寸法の影響を受けることなしに、パンチがワークに食い込むことはない。【選択図】図1 |
