Base do moinho<\/span><\/h1>\n

Requisitos mais importantes para a base do moinho<\/span><\/h2>\n

A base do laminador, tamb\u00e9m chamada de "camada", suporta os suportes, eixos, cilindros, transmiss\u00e3o e os componentes necess\u00e1rios para formar as se\u00e7\u00f5es. Os requisitos mais importantes para a base s\u00e3o:<\/p>\n

    \n
  1. \u00a0Rigidez durante a opera\u00e7\u00e3o, transporte e instala\u00e7\u00e3o.<\/li>\n
  2. \u00a0Superf\u00edcie superior lisa e nivelada para instala\u00e7\u00e3o dos componentes.<\/li>\n
  3. \u00a0Uma chaveta ou outro componente a ser usado para alinhar os suportes.<\/li>\n
  4. \u00a0Drenagem do lubrificante de conforma\u00e7\u00e3o por rolos<\/li>\n<\/ol>\n

    Introdu\u00e7\u00e3o \u00e0 Base do Moinho<\/span><\/h2>\n

    Bases de laminadores longas podem precisar ser divididas em duas ou mais se\u00e7\u00f5es para facilitar a usinagem, o manuseio (eleva\u00e7\u00e3o) e o transporte. Se a base for dividida, se houver previs\u00e3o de expans\u00e3o ou se outras unidades forem acopladas posteriormente, placas adicionais e dispositivos de jun\u00e7\u00e3o dever\u00e3o ser instalados nas extremidades de jun\u00e7\u00e3o das bases dos laminadores. As bases dos laminadores devem ser capazes de acomodar a recircula\u00e7\u00e3o do lubrificante utilizado durante a conforma\u00e7\u00e3o. No caso de bases divididas, deve-se atentar para a recircula\u00e7\u00e3o em cada se\u00e7\u00e3o da base e para a cria\u00e7\u00e3o de um sistema de recircula\u00e7\u00e3o eficiente.
    \njunta estanque entre as bases.<\/p>\n

    Na maioria dos casos, a base tamb\u00e9m suporta o sistema de transmiss\u00e3o. As caixas de engrenagens que acionam os suportes raramente s\u00e3o montadas em uma base separada. N\u00e3o existe um projeto padr\u00e3o para a base de moinhos, mas a maioria das bases \u00e9 constru\u00edda de forma semelhante, seja com chapas ou com se\u00e7\u00f5es tubulares. A superf\u00edcie superior da placa superior \u00e9 totalmente usinada ou usinada apenas ao longo das bordas longitudinais onde os suportes e as caixas de engrenagens s\u00e3o montados. Uma chaveta de alinhamento \u00e9 usinada em toda a extens\u00e3o da placa superior. A chaveta (ou outros componentes) deve ser reta, com uma toler\u00e2ncia de 0,025 a 0,050 mm em toda a extens\u00e3o do moinho, mesmo que seja montado a partir de se\u00e7\u00f5es. Furos s\u00e3o feitos e roscados para a montagem dos suportes e outros componentes. As bordas superiores das laterais da base s\u00e3o soldadas \u00e0 placa superior, e as bordas inferiores s\u00e3o fixadas a uma estrutura de suporte. Placas de nivelamento e funda\u00e7\u00e3o s\u00e3o fixadas \u00e0 estrutura. Placas transversais e outros elementos soldados na cavidade da base proporcionam rigidez e suporte adicionais.<\/p>\n

    Sistema de lubrifica\u00e7\u00e3o na base do moinho<\/span><\/h3>\n

    Para garantir o retorno do lubrificante, a maioria dos moinhos possui um canal ao redor do per\u00edmetro superior. Frequentemente, esses canais s\u00e3o feitos de cantoneiras estruturais soldadas \u00e0 base, com um espa\u00e7o suficiente para o lubrificante e para facilitar a limpeza. \u00c9 \u00fatil que o fundo do canal seja inclinado em dire\u00e7\u00e3o \u00e0 abertura de descarga do l\u00edquido. Durante a constru\u00e7\u00e3o, a parte superior da aba vertical externa da cantoneira deve ficar acima da base do moinho. A aba saliente, usinada para ficar nivelada com a base do moinho, fornece suporte adicional aos suportes externos durante a troca e instala\u00e7\u00e3o de ferramentas.<\/p>\n

    Considera\u00e7\u00f5es Especiais para a Base do Moinho<\/span><\/h3>\n

    Deve-se dar aten\u00e7\u00e3o especial aos suportes do motor\/engrenagem\/transmiss\u00e3o. Se a placa superior for recortada ao redor do centro do moinho para dar espa\u00e7o \u00e0 correia ou corrente de transmiss\u00e3o, a rigidez da base ser\u00e1 comprometida.
    \nDeve ser verificado novamente. O recorte pode precisar ser refor\u00e7ado. Em laminadores que se deslocam lateralmente sobre trilhos, deve-se fornecer suporte adequado para os rod\u00edzios (ou guias) e as for\u00e7as exercidas durante o movimento lateral devem ser verificadas.<\/p>\n

    Na maioria dos casos, a altura da base do laminador \u00e9 calculada para proporcionar uma altura de passagem confort\u00e1vel para o produto. Normalmente, a altura da linha de passagem \u00e9 definida entre 900 e 1025 mm acima do piso. No entanto, o tamanho dos suportes, o tipo de prensas, outras opera\u00e7\u00f5es secund\u00e1rias na linha e o m\u00e9todo de manuseio do material podem determinar a altura real da linha de passagem. Se a altura da linha de passagem for muito alta, uma plataforma de trabalho\/circula\u00e7\u00e3o deve ser instalada ao lado do operador do laminador. Contudo, a seguran\u00e7a e a fadiga (a frequ\u00eancia com que o operador precisa subir e descer da plataforma) s\u00e3o fatores adicionais a serem considerados. Portanto, ocasionalmente, a prensa de corte ou outro equipamento \u00e9 instalado em um fosso para criar uma altura de linha de passagem confort\u00e1vel para os operadores.<\/p>\n
