PRINCIPE D'\u00c9TIRAGE \u00c0 FROID<\/strong><\/h2>\n

L'\u00e9tirage \u00e0 froid est une technologie de traitement des mat\u00e9riaux. Pour les mat\u00e9riaux m\u00e9talliques, l'\u00e9tirage \u00e0 froid d\u00e9signe un \u00e9tirage \u00e0 temp\u00e9rature ambiante afin d'obtenir une certaine forme et certaines propri\u00e9t\u00e9s m\u00e9caniques.<\/p>\n

L'\u00e9tirage \u00e0 froid est g\u00e9n\u00e9ralement un processus d'\u00e9tirage forc\u00e9 du mat\u00e9riau \u00e0 travers le trou de matrice de tr\u00e9filage en alliage dur, qui est plus r\u00e9sistant que l'\u00e9tirage pur. Le mat\u00e9riau \u00e9tir\u00e9 \u00e0 froid est non seulement \u00e9tir\u00e9 longitudinalement, mais \u00e9galement soumis \u00e0 une extrusion lat\u00e9rale en m\u00eame temps. Apr\u00e8s une ou plusieurs fois d'\u00e9tirage \u00e0 froid, le r\u00e9seau interne glisse, la r\u00e9sistance \u00e0 la traction peut \u00eatre augment\u00e9e de 50% \u00e0 90%, et la duret\u00e9 est augment\u00e9e, mais la plasticit\u00e9 est consid\u00e9rablement r\u00e9duite.<\/p>\n

La situation des voitures particuli\u00e8res de taille moyenne est similaire \u00e0 celle des grandes voitures particuli\u00e8res. Il existe de nombreuses vari\u00e9t\u00e9s et sp\u00e9cifications utilis\u00e9es dans les petites voitures, et la plupart des sections transversales sont plus complexes et les exigences de pr\u00e9cision dimensionnelle sont strictes.<\/p>\n <\/p>\n Les camions (y compris les camions l\u00e9gers) utilisent le plus grand nombre de sections \u00e9tir\u00e9es \u00e0 froid dans le compartiment. Selon les diff\u00e9rents mod\u00e8les de voiture, la structure du mod\u00e8le de voiture est \u00e9galement diff\u00e9rente.
