Projeto de M\u00e1quina de Conforma\u00e7\u00e3o de Perfis<\/span><\/strong><\/h2>\r\n\r\n\r\n\r\n

Complexidade dos desenhos de perfil<\/span><\/strong><\/h3>\r\n\r\n\r\n\r\n

Os desenhos de perfil dos perfis conformados a frio s\u00e3o o fator mais importante no projeto dos rolos da m\u00e1quina de conforma\u00e7\u00e3o a frio.<\/p>\r\n\r\n\r\n\r\n

A variedade de formas n\u00e3o \u00e9 limitada. E as formas podem ser classificadas arbitrariamente como Simples, Abertas, Fechadas, de Complexidade M\u00e9dia, Muito Complexas e Pain\u00e9is.<\/p>\r\n\r\n\r\n\r\n

\"Desenhos<\/figure>\r\n\r\n\r\n\r\n

A profundidade do perfil afeta o projeto dos rolos da m\u00e1quina de perfilagem.<\/span><\/strong><\/h3>\r\n\r\n\r\n\r\n

A profundidade do perfil corresponde \u00e0 dimens\u00e3o vertical m\u00e1xima da se\u00e7\u00e3o de a\u00e7o ao sair dos \u00faltimos est\u00e1gios de conforma\u00e7\u00e3o. Essa profundidade influencia o n\u00famero de est\u00e1gios de conforma\u00e7\u00e3o necess\u00e1rios e, consequentemente, o projeto da m\u00e1quina de conforma\u00e7\u00e3o. Para uma mesma se\u00e7\u00e3o transversal, quanto maior a profundidade, maior o n\u00famero de est\u00e1gios de conforma\u00e7\u00e3o necess\u00e1rios.\u00a0<\/p>\r\n\r\n\r\n\r\n

Largura da parte plana<\/span><\/strong><\/h3>\r\n\r\n\r\n\r\n

A largura da parte plana, a se\u00e7\u00e3o n\u00e3o conformada, geralmente n\u00e3o influencia o n\u00famero de passes de perfilagem. No entanto, quanto mais larga a se\u00e7\u00e3o plana (parte n\u00e3o conformada) e mais fino o material, maior a possibilidade de ocorr\u00eancia de ondula\u00e7\u00f5es. Independentemente da qualidade do projeto dos cilindros, eles n\u00e3o podem eliminar completamente as ondula\u00e7\u00f5es. No projeto de cilindros de m\u00e1quinas de perfilagem, existem muitas maneiras de reduzir ou eliminar ondula\u00e7\u00f5es nas bordas ou no centro.<\/p>\r\n\r\n\r\n\r\n

Componentes largos, planos e sem forma definida apresentar\u00e3o diferentes dificuldades durante a conforma\u00e7\u00e3o por rolos. Se apenas um lado do produto for conformado e o restante da tira for largo e plano, uma pequena press\u00e3o nessa parte plana far\u00e1 com que ela se alongue. Esse elemento alongado pode criar curvatura, tor\u00e7\u00e3o ou ondula\u00e7\u00e3o nas bordas.<\/p>\r\n\r\n\r\n\r\n

Durante a conforma\u00e7\u00e3o por rolos de pain\u00e9is largos e sulcados, a conforma\u00e7\u00e3o \u00e0s vezes come\u00e7a na nervura central. Nesses casos, al\u00e9m da modifica\u00e7\u00e3o progressiva dos \u00e2ngulos de dobra de passe para passe, se\u00e7\u00f5es planas relativamente largas em ambos os lados precisam ser deslocadas lateralmente, dentro do mesmo plano, cada vez mais pr\u00f3ximas do centro. Deslocar uma chapa fina e plana lateralmente sem criar grandes ondula\u00e7\u00f5es n\u00e3o \u00e9 uma tarefa f\u00e1cil.<\/p>\r\n\r\n\r\n\r\n

\"rolos<\/figure>\r\n\r\n\r\n\r\n

A toler\u00e2ncia da se\u00e7\u00e3o transversal afeta o projeto dos rolos da m\u00e1quina de perfilagem.<\/span><\/strong><\/h3>\r\n\r\n\r\n\r\n

O cliente, o projetista da se\u00e7\u00e3o transversal e o projetista da m\u00e1quina de perfilagem devem concordar com a interpreta\u00e7\u00e3o das dimens\u00f5es e toler\u00e2ncias especificadas nos desenhos dos perfis antes do in\u00edcio do projeto dos rolos da m\u00e1quina de perfilagem.<\/p>\r\n\r\n\r\n\r\n

As toler\u00e2ncias do produto tamb\u00e9m afetar\u00e3o o projeto do rolo. Quanto menor a toler\u00e2ncia, mais suportes ser\u00e3o necess\u00e1rios.<\/p>\r\n\r\n\r\n\r\n

Toler\u00e2ncias de retilineidade e planicidade<\/span><\/strong><\/h3>\r\n\r\n\r\n\r\n

A curvatura, o arqueamento, a tor\u00e7\u00e3o, o efeito de arco, o efeito espinha de peixe, a ondula\u00e7\u00e3o nas bordas ou no centro podem ser causados pela natureza da conforma\u00e7\u00e3o por rolos, bem como por imperfei\u00e7\u00f5es no material, no equipamento e na configura\u00e7\u00e3o. As ferramentas t\u00eam grande influ\u00eancia nas tens\u00f5es residuais, que criam desvios de retilineidade e planicidade. Um bom projeto de conforma\u00e7\u00e3o por rolos elimina ou minimiza esses problemas; um projeto ruim os cria ou os agrava.<\/p>\r\n\r\n\r\n\r\n
