Os materiais s\u00e3o selecionados para atender aos requisitos espec\u00edficos do produto ao menor pre\u00e7o poss\u00edvel. <\/span>No entanto, as propriedades mec\u00e2nicas, a superf\u00edcie, o desvio de espessura, a largura, a retilineidade e a planicidade da mat\u00e9ria-prima influenciam o projeto da m\u00e1quina de perfilagem.<\/span><\/p>\n

Propriedades Mec\u00e2nicas<\/strong><\/h2>\n

Durante processo de conforma\u00e7\u00e3o de rolos<\/a>, a deforma\u00e7\u00e3o (alongamento) da fibra externa da tira deve permanecer abaixo da deforma\u00e7\u00e3o uniforme de engenharia. <\/span>Portanto, o projetista da m\u00e1quina de conforma\u00e7\u00e3o deve conhecer a resist\u00eancia ao escoamento, a resist\u00eancia m\u00e1xima \u00e0 tra\u00e7\u00e3o e o alongamento do material. <\/span>Esses dados geralmente est\u00e3o dispon\u00edveis junto ao fornecedor do material.<\/span><\/p>\n

Em a\u00e7os de baixo carbono, a correla\u00e7\u00e3o entre dureza e resist\u00eancia \u00e0 tra\u00e7\u00e3o \u00e9 razoavelmente boa. <\/span>Portanto, a dureza \u00e9 \u00e0s vezes usada para verificar se o material \u00e9 macio ou duro.\u00a0<\/span>No entanto, um material com boa dureza n\u00e3o garante uma boa conformabilidade.<\/span> O trabalho a frio, como a conforma\u00e7\u00e3o por rolos, o tensionamento, a compress\u00e3o e outras opera\u00e7\u00f5es, aumenta a resist\u00eancia ao escoamento e \u00e0 tra\u00e7\u00e3o, e reduz o alongamento.<\/span>
\n<\/span><\/p>\n

Com base na experi\u00eancia anterior, o projetista de m\u00e1quinas de perfilagem geralmente consegue prever a conformabilidade do material, incluindo o raio m\u00ednimo e o retorno el\u00e1stico. <\/span>Materiais com alta resist\u00eancia ao escoamento, pequena diferen\u00e7a entre as tens\u00f5es de tra\u00e7\u00e3o e de escoamento e pequeno alongamento requerem mais passes de conforma\u00e7\u00e3o.<\/span><\/p>\n

O retorno el\u00e1stico do material influencia o projeto da m\u00e1quina de perfilagem.<\/strong><\/h2>\n

O m\u00e9todo de conforma\u00e7\u00e3o por rolos e o m\u00f3dulo de elasticidade do material influenciar\u00e3o as propriedades mec\u00e2nicas do material, incluindo o retorno el\u00e1stico.<\/p>\n

Toler\u00e2ncia de <\/strong>Influ\u00eancia do material no projeto de m\u00e1quinas de perfilagem<\/strong><\/h2>\n

Grossura<\/strong><\/h3>\n

O material deve ser capaz de passar pelo espa\u00e7o entre os rolos sem redu\u00e7\u00e3o de espessura. <\/span>Portanto, a folga do rolo \u00e9 calculada como a soma da espessura m\u00e1xima especificada, mais a toler\u00e2ncia m\u00e1xima de espessura, mais a espessura m\u00e1xima do revestimento, mais a profundidade m\u00e1xima de estampagem.<\/span><\/p>\n

Tentar conformar materiais mais espessos do que a espessura m\u00e1xima especificada pode quebrar os rolos, danificar o equipamento, reduzir a qualidade do produto e, adicionalmente, causar ondula\u00e7\u00f5es, arranh\u00f5es ou outros problemas.<\/span>\u00a0A espessura tamb\u00e9m afeta a largura da tira. <\/span>A largura e as dimens\u00f5es s\u00e3o calculadas com base na espessura m\u00e9dia. <\/span>Se a espessura estiver no limite m\u00e1ximo com a toler\u00e2ncia, algumas dimens\u00f5es ser\u00e3o menores. E <\/span>Se a espessura estiver dentro da toler\u00e2ncia negativa, algumas dimens\u00f5es ser\u00e3o maiores.<\/span><\/p>\n

Largura<\/strong><\/h3>\n

A toler\u00e2ncia de largura obviamente influenciar\u00e1 algumas dimens\u00f5es do produto. Na maioria dos casos, a toler\u00e2ncia de largura da tira se somar\u00e1 \u00e0 toler\u00e2ncia de conforma\u00e7\u00e3o por rolos na borda externa. Se essa dimens\u00e3o for cr\u00edtica e rigorosamente controlada, o excesso de material poder\u00e1 se acumular no centro, criando ondula\u00e7\u00f5es e outros problemas.<\/p>\n
