Title
(EN) METHOD OF MANUFACTURING FERRULE
(FR) PROCEDE DE FABRICATION DE PASSE-FIL
Abstract
(EN) A method of manufacturing a ferrule by drawing or extruding a thread after pre-setting the outside and inside diameter dimensions of a tube-shaped object, through which the thread is inserted, by dieing, rolling, swaging, pressing, or drawing, characterized in that a production control is easy, the skill of a worker is not necessarily required, and thus a fraction defective is low and productivity is high, whereby such expensive equipment as a forming machine and metal mold is not needed, and the ferrule can be produced at low energy cost, with high dimensional accuracy and dimensional stability by a general inexpensive equipment, and also a multi-core ferrule of 2-core or more can be produced easily.
(FR) Cette invention concerne un procédé de fabrication de passe-fil consistant à réaliser par étirage ou extrusion un filetage après réglage des cotes extérieures et intérieures d'un objet tubulaire au travers duquel ledit filetage est inséré par matriçage, rectifiage, emboutissage, pressage ou étirage. Ce procédé se caractérise en ce qu'il simplifier le contrôle de la production, qu'il ne requiert pas l'intervention d'un ouvrier qualifié que le taux de rebut est faible et la productivité élevée, qu'il ne nécessite pas l'utilisation de matériels coûteux tels qu'une machine à former ou une installation de moulage à coquille métallique, et que le passe-fil peut être fabriqué sans grande dépense d'énergie, avec une précision et une stabilité dimensionnelle élevées, en utilisant un matériel universel bon marché, et qu'il se prête à la fabrication de passe-fil multi- ou bi-câble.
