@ Procédé et dispositif pour le traitement de fil métallique laminé, destiné à la fabrication de ressorts, en particulier de ressorts à boudino
La présente invention se rapporte à un procédé et un dispositif pour le traitement de fil métallique laminé destiné à la fabrication de ressorts, en particulier de ressorts à boudin.
Le fil métallique laminé pour la fabrication de ressorts à boudin a jusqu'ici été trempé par re- froidissement brusque immédiatement après le laminage, à la chaleur du laminage. Ce procédé provoque des irré- gularités dans la texture du fil métallique soumis au refroidissement brusque, et par suite aussi une diffé- rence dans les ressorts fabriqués ultérieurement avec ce fil métallique. La cause de ce fait réside, en partie
<Desc/Clms Page number 2>
dans la température variable de* laminage des différentes couronnes de fil métallique et aussi des différentes parties de fil métallique d'une seule et même couronne, et, en partie, dans le refroidissement brusque irrégulier
EMI2.1
produit par l'eau. L'tnventlon a pour but d'éviter ces in- convénients.
Le dessin ci-joint représente une forme ci 'exécution d'un dispositif servant à la réalisation du procédé suivant l'invention.
Le dispositif consiste en une bobine aun four à
EMI2.2
réchauller b avec ouvertures d'entrée et de sortie e et pour le ftl métallique e, une cuve à eau avec galets de guidage g, et une deuxiérne bobine h. Les différents éléments sont, comme il est visible sur le dessin, disposés à la suite l'un de l'autre.
Avec le dispositif décrit, le procédé est réalisé
EMI2.3
de la mantère suivante: On laisse les couronnes de fil métallique se refroidir après le laminage, on les place sur la bobine a , et on fait passer le fil métallique,
EMI2.4
en le déroulant de la bobine, a travers le four à ré- chau,fer b (ou à travers un autre système de 7,échauffage).
Dans ce ,our, on porte le fil métallique sur toute sa longueur à la même température, Du faur b , le fil mué talltque est entraîné, en passant sous les galets de guidage g, à travers la cuve à eau,- est refroidi brusque- ment dans l'eau, et est ensuite enroulé sur'la bobine h.
De la manière indiquée, on obtient un produit absolument uniforme.

@ Method and device for the treatment of rolled metal wire, intended for the manufacture of springs, in particular coil springs
The present invention relates to a method and a device for the treatment of rolled metal wire intended for the manufacture of springs, in particular coil springs.
Rolled metal wire for the manufacture of coil springs has heretofore been quenched by sudden cooling immediately after rolling, in the heat of rolling. This process causes irregularities in the texture of the wire subjected to the sudden cooling, and hence also a difference in the springs subsequently produced with this wire. The cause of this fact lies, in part
<Desc / Clms Page number 2>
in the variable rolling temperature of the different rings of wire and also of the different parts of the wire of one and the same crown, and, in part, in the sudden irregular cooling
EMI2.1
produced by water. The aim of the invention is to avoid these disadvantages.
The accompanying drawing shows one embodiment of a device for carrying out the method according to the invention.
The device consists of a coil in a
EMI2.2
warmer b with inlet and outlet openings e and for the metallic ftl e, a water tank with guide rollers g, and a second coil h. The different elements are, as can be seen in the drawing, arranged one after the other.
With the device described, the method is carried out
EMI2.3
of the following mantera: The wire rings are allowed to cool after lamination, they are placed on the spool a, and the wire is passed through,
EMI2.4
by unwinding it from the reel, through the reheating oven, iron b (or through another 7 system, reheating).
In this, our, the metal wire is brought over its entire length to the same temperature, Du faur b, the molten wire is entrained, passing under the guide rollers g, through the water tank, - is suddenly cooled - ment in water, and is then wound onto the coil h.
As indicated, an absolutely uniform product is obtained.
