Conformaci\u00f3 controlada per a politges d’automoci\u00f3 d’alta precisi\u00f3. Estalvi de material, concentricitat estable i geometria de ranura repetible. Fins a 200 peces per hora amb consist\u00e8ncia industrial.<\/p>\n\n
El repte<\/mark><\/h2>\n\n
Els sistemes de transmissi\u00f3 exigeixen precisi\u00f3.<\/p>\n\n
La fabricaci\u00f3 tradicional de politges es basava en gran mesura en operacions de mecanitzat i premsat. Aix\u00f2 significava un major malbaratament de material, temps de cicle m\u00e9s llargs i costos d’utillatge que limitaven la flexibilitat.<\/p>\n\n
Els fabricants necessitaven:<\/p>\n\n
\n
Consum redu\u00eft de materials<\/li>\n\n\n\n
Alta precisi\u00f3 de ranura<\/li>\n\n\n\n
Concentricitat estable<\/li>\n\n\n\n
alts ritmes de producci\u00f3<\/li>\n\n\n\n
Rendiment fiable del contacte amb la corretja<\/li>\n<\/ul>\n\n
Tot mantenint unes estrictes toler\u00e0ncies d’automoci\u00f3<\/p>\n\n
La soluci\u00f3 DENN<\/mark><\/h2>\n\n
DENN va desenvolupar una estrat\u00e8gia de conformat controlat utilitzant tecnologies de forja rotativa i ranurat rotatiu<\/strong> , implementada en m\u00e0quines RF i MPT.<\/p>\n\n
En lloc d’eliminar material mitjan\u00e7ant el mecanitzat, li donem forma mitjan\u00e7ant una deformaci\u00f3 controlada.<\/p>\n\n
Segons el tipus de politja (trapezo\u00efdal, multicanal o Poly-V), el proc\u00e9s pot incloure:<\/p>\n\n
\n
Producci\u00f3 de preformes amb forma gaireb\u00e9 neta mitjan\u00e7ant forja rotativa (RF)<\/li>\n\n\n\n
Operacions de divisi\u00f3 i conformaci\u00f3 a partir de discs plans<\/li>\n\n\n\n
Ranurat progressiu amb rodets perfilats<\/li>\n\n\n\n
Conformaci\u00f3 multipassada per acumular material en zones cr\u00edtiques<\/li>\n\n\n\n
Conformaci\u00f3 final amb concentricitat controlada<\/li>\n<\/ul>\n\n
El material flueix on es necessita. Sense exc\u00e9s. Sense eliminacions innecess\u00e0ries. <\/p>\n\n
El resultat<\/mark><\/h2>\n\n
La deformaci\u00f3 controlada proporciona:<\/p>\n\n
\n
Important estalvi de material en comparaci\u00f3 amb el mecanitzat<\/li>\n\n\n\n
Ritmes de producci\u00f3 de fins a 200 peces per hora<\/li>\n\n\n\n
Alta precisi\u00f3 i repetibilitat de ranura<\/li>\n\n\n\n
Acabat superficial compactat que millora la vida \u00fatil de la corretja<\/li>\n\n\n\n
Reducci\u00f3 de la desviaci\u00f3 axial i radial<\/li>\n<\/ul>\n\n
Les politges Poly-V, cada cop m\u00e9s utilitzades en sistemes de transmissi\u00f3 d’autom\u00f2bils, es beneficien especialment d’aquest proc\u00e9s, ja que combinen una alta capacitat de transmissi\u00f3 de pot\u00e8ncia amb una geometria estable i una producci\u00f3 eficient.<\/p>\n\n\n<\/figure>\n\n\n\n<\/figure>\n\n\n\n<\/figure>\n<\/figure>\n\n
Per qu\u00e8 \u00e9s important<\/mark><\/h2>\n\n
Quan les toler\u00e0ncies s\u00f3n ajustades i els volums s\u00f3n alts, l’estabilitat defineix la competitivitat.<\/p>\n\n
En substituir els processos subtractius per un conformat controlat, els fabricants redueixen els residus, milloren les propietats mec\u00e0niques i augmenten la consist\u00e8ncia de la producci\u00f3.<\/p>\n\n
A DENN, no nom\u00e9s formem politges. Controlem el flux de material per estabilitzar el rendiment de la transmissi\u00f3, pe\u00e7a rere pe\u00e7a.<\/p>\n","protected":false},"featured_media":8866,"template":"","format":"standard","meta":{"_acf_changed":false,"inline_featured_image":false},"class_list":["post-10741","projects","type-projects","status-publish","format-standard","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"\n
