Les poin\u00e7ons en carbure sont l’un des composants cl\u00e9s utilis\u00e9s dans divers processus de fabrication, en particulier dans des industries telles que l’emboutissage et la d\u00e9coupe de t\u00f4les. Le poin\u00e7on en carbure de tungst\u00e8ne est utilis\u00e9 avec un insert de matrice comme un ensemble complet de poin\u00e7ons et de matrices.<\/p>\n\n\n\n

Ils sont bien s\u00fbr fabriqu\u00e9s \u00e0 partir de carbure et sont parfois fabriqu\u00e9s \u00e0 partir de PM ou de HSS. Mais le carbure est le meilleur choix, car il s\u2019agit d\u2019un mat\u00e9riau m\u00e9tallique dur connu pour sa duret\u00e9, sa r\u00e9sistance \u00e0 l\u2019usure et sa durabilit\u00e9. Il existe diff\u00e9rents types de marques et de mod\u00e8les de carbure, comme Fujilloy, Sanalloy, Everloy, Cbceratizit, etc. Certains mod\u00e8les de carbure couramment utilis\u00e9s sont KD20, RD50, KX03, RG3, FD15, FD25, GA20, H40S et CD650, etc.<\/p>\n\n\n\n

Voyons quelques-unes des principales caract\u00e9ristiques et applications des poin\u00e7ons en carbure :<\/p>\n\n\n\n

Caract\u00e9ristiques des poin\u00e7ons en carbure<\/h2>\n\n\n\n

Duret\u00e9:\u00a0<\/h3>\n\n\n\n

Les poin\u00e7ons en carbure sont extr\u00eamement durs et peuvent r\u00e9sister \u00e0 des applications \u00e0 haute pression sans se d\u00e9former ni se casser. Cette duret\u00e9 les rend id\u00e9ales pour une utilisation dans les op\u00e9rations de poin\u00e7onnage o\u00f9 un outil tranchant et durable est requis.<\/p>\n\n\n\n

R\u00e9sistance \u00e0 l\u2019usure\u00a0:\u00a0<\/h3>\n\n\n\n

Les poin\u00e7ons en carbure ont une excellente r\u00e9sistance \u00e0 l\u2019usure, ce qui signifie qu\u2019ils conservent leur tranchant et leur pr\u00e9cision dimensionnelle m\u00eame apr\u00e8s une utilisation prolong\u00e9e. Cette propri\u00e9t\u00e9 prolonge la dur\u00e9e de vie de l\u2019outil et r\u00e9duit le besoin de remplacements fr\u00e9quents.<\/p>\n\n\n\n

Pr\u00e9cision:<\/strong><\/h3>\n\n\n\n

Les poin\u00e7ons en carbure peuvent \u00eatre fabriqu\u00e9s avec une grande pr\u00e9cision, garantissant des r\u00e9sultats constants et pr\u00e9cis dans les op\u00e9rations de poin\u00e7onnage et de formage. Cette pr\u00e9cision est cruciale dans les industries o\u00f9 des tol\u00e9rances serr\u00e9es sont requises.<\/p>\n\n\n\n

Rentabilit\u00e9 :<\/h3>\n\n\n\n

Bien que les poin\u00e7ons en carbure puissent avoir un co\u00fbt initial plus \u00e9lev\u00e9 que les mat\u00e9riaux d\u2019outillage traditionnels, leur durabilit\u00e9 et leurs performances se traduisent souvent par des \u00e9conomies de co\u00fbts \u00e0 long terme. La r\u00e9duction des temps d\u2019arr\u00eat et des co\u00fbts de remplacement des outils contribue \u00e0 leur rentabilit\u00e9 globale.<\/p>\n\n\n\n

Applications des poin\u00e7ons en carbure<\/h2>\n\n\n\n

Les poin\u00e7ons en carbure peuvent \u00eatre utilis\u00e9s avec une vari\u00e9t\u00e9 de mat\u00e9riaux, notamment les m\u00e9taux, les plastiques, les c\u00e9ramiques et les composites. Ils sont utilis\u00e9s pour des t\u00e2ches telles que le poin\u00e7onnage, l’estampage, le formage et le fa\u00e7onnage des mat\u00e9riaux.<\/p>\n\n\n\n

Ils conviennent au poin\u00e7onnage de t\u00f4les, au per\u00e7age de trous, au formage de formes, au gaufrage et \u00e0 d’autres t\u00e2ches similaires sur diff\u00e9rents mat\u00e9riaux.<\/p>\n\n\n\n

Ce sont des composants d’outils essentiels dans de nombreux processus de fabrication. Surtout dans le processus de fabrication micro\u00e9lectronique. Par exemple, des micro-connecteurs et des micro-borniers, des composants de t\u00e9l\u00e9phones portables et d’ordinateurs, etc.<\/p>\n\n\n\n

Types de poin\u00e7ons en carbure<\/h2>\n\n\n\n

Il existe diff\u00e9rents types de poin\u00e7ons en carbure. Selon la classification des formes, certains sont des poin\u00e7ons cylindriques en carbure, d’autres sont des poin\u00e7ons rectangulaires et carr\u00e9s.<\/p>\n\n\n\n

Il existe certaines marques de poin\u00e7ons standard comme les poin\u00e7ons en carbure Dayton, les poin\u00e7ons en carbure Misumi, les poin\u00e7ons et matrices en carbure \u00e0 vie. Mais la plupart des poin\u00e7ons sont fabriqu\u00e9s sur mesure selon des conceptions et des dessins sp\u00e9cifiques.<\/p>\n\n\n\n

Ces types de pointage personnalis\u00e9s peuvent \u00eatre appel\u00e9s comme ci-dessous :<\/p>\n\n\n\n

Poin\u00e7ons vierges en carbure<\/p>\n\n\n\n

Poin\u00e7ons de formage en carbure<\/p>\n\n\n\n

Poin\u00e7ons d’estampage en carbure<\/p>\n\n\n\n

Poin\u00e7ons droits en carbure<\/p>\n\n\n\n

Poin\u00e7ons en carbure<\/p>\n\n\n\n

Poin\u00e7ons de per\u00e7age en carbure<\/p>\n\n\n\n

Poin\u00e7ons pilotes en carbure<\/p>\n\n\n\n

Poin\u00e7ons en carbure pour rectification de profils<\/p>\n\n\n\n

Lacunes des poin\u00e7ons en carbure<\/h2>\n\n\n\n

Bien que le poin\u00e7on en carbure pr\u00e9sente quelques bonnes caract\u00e9ristiques, il pr\u00e9sente \u00e9galement quelques faiblesses. Comme c’est trop dur, la duret\u00e9 peut \u00eatre d’environ 89-95 HRC. Il n’est pas facile \u00e0 traiter, il suffit d’utiliser un \u00e9quipement d’usinage tr\u00e8s co\u00fbteux pour traiter le mat\u00e9riau, par exemple, une rectification de profil et une rectification de surface avec des meules diamant\u00e9es de bonne qualit\u00e9, ou une EDM \u00e0 fil ou une EDM \u00e0 plomb. Son co\u00fbt mat\u00e9riel et son co\u00fbt de fabrication sont donc tous deux \u00e9lev\u00e9s.<\/p>\n\n\n\n

Il y a une autre faiblesse, c’est qu’il peut facilement \u00eatre endommag\u00e9 en tombant au sol. Bien qu\u2019il soit dur, il est \u00e9galement croustillant et facile \u00e0 casser. Le package est donc tr\u00e8s important. Habituellement, il est emball\u00e9 dans une bo\u00eete en plastique avec du coton perl\u00e9, et \u00e9galement fix\u00e9 par un ruban de papier.<\/p>\n\n\n\n

Poin\u00e7ons et matrices en carbure<\/h2>\n\n\n\n

Comme nous l’avons mentionn\u00e9 ci-dessus, les poin\u00e7ons et matrices en carbure sont un ensemble d’outils utilis\u00e9s ensemble. Les matrices d\u00e9signent ici les inserts de matrice en carbure avec des trous correspondant exactement aux poin\u00e7ons en carbure. Habituellement, un insert de matrice doit conserver un jeu, un angle d’inclinaison et un angle conique \u00e0 certains endroits pour garantir une utilisation correcte.<\/p>\n\n\n\n

Fabricants de poin\u00e7ons en carbure<\/h2>\n\n\n\n

Il existe de nombreux fabricants de poin\u00e7ons en carbure de tungst\u00e8ne aux \u00c9tats-Unis, au Japon, en Chine et m\u00eame en Inde. Certaines marques c\u00e9l\u00e8bres comme Oberg Industries, Endurance Carbide, Raven Carbide Die et Langdi Precision. Pour certains fournisseurs de poin\u00e7ons en carbure aux \u00c9tats-Unis, les co\u00fbts de production peuvent \u00eatre tr\u00e8s \u00e9lev\u00e9s et certaines usines de poin\u00e7ons en carbure en Chine peuvent \u00eatre plus rentables, comme Langdi Precision. Tout d\u00e9pend des choix des clients.<\/p>\n\n\n\n

Dans l\u2019ensemble, les poin\u00e7ons en carbure offrent des performances et une long\u00e9vit\u00e9 sup\u00e9rieures par rapport aux poin\u00e7ons traditionnels fabriqu\u00e9s \u00e0 partir de mat\u00e9riaux comme l\u2019acier. La fabrication de poin\u00e7ons en carbure est un travail tr\u00e8s sophistiqu\u00e9 qui n\u00e9cessite des machinistes chevronn\u00e9s et des technologies d’usinage avanc\u00e9es.<\/p>\n\n\n\n
