No nosso dia a dia, se observarmos com aten\u00e7\u00e3o as conex\u00f5es das m\u00e1quinas e equipamentos \u2013 parafusos, veremos que muitas m\u00e1quinas e equipamentos est\u00e3o utilizando parafusos hexagonais<\/a>, por que \u00e9 isso? Quais s\u00e3o as vantagens dos parafusos hexagonais para a conex\u00e3o de equipamentos mec\u00e2nicos? Diante dessas quest\u00f5es, o Pr\u00edncipe Fastener de acordo com o entendimento espec\u00edfico para explicar o problema a todos.<\/p>

Parafusos de cabe\u00e7a sextavada<\/a> s\u00e3o arredondados por fora, o meio \u00e9 hexagonal c\u00f4ncavo. Tal estrutura de fato, as vantagens s\u00e3o muito \u00f3bvias.<\/p>

1, tendo maior carga. Ele tem seis superf\u00edcies de suporte de for\u00e7a, em compara\u00e7\u00e3o com apenas dois lados de um parafuso de palavra e os parafusos em forma de cruz carregam mais o parafuso.<\/p>

Nota: O material do parafuso sextavado<\/a> geralmente \u00e9 feito de a\u00e7o inoxid\u00e1vel, a\u00e7o carbono, liga de a\u00e7o e outros estilos de parafusos, basicamente n\u00e3o h\u00e1 diferen\u00e7a no material, quanto maior o n\u00edvel de desempenho de alta resist\u00eancia, maior a escolha de parafusos, certifique-se de selecionar o n\u00edvel de desempenho apropriado de parafusos estritamente de acordo com os requisitos de uso, o n\u00edvel \u00e9 diferente, o pre\u00e7o n\u00e3o \u00e9 o mesmo.<\/p>

2, pode ser processamento rebaixado. Ou seja, toda a porca \u00e9 afundada no interior da pe\u00e7a de trabalho, o que pode manter a superf\u00edcie da pe\u00e7a de trabalho plana e bonita.<\/p>

\"Parafuso

3, \u00e9 f\u00e1cil de instalar. Em compara\u00e7\u00e3o com os parafusos hexagonais externos, o hex\u00e1gono \u00e9 adequado para mais ocasi\u00f5es de montagem, especialmente ocasi\u00f5es estreitas, por isso \u00e9 conveniente ao montar e reparar e depurar conveniente.<\/p>

4, n\u00e3o \u00e9 f\u00e1cil de desmontar. As ferramentas que normalmente usamos s\u00e3o chaves vivas, chaves de fenda e chaves ma\u00e7antes, etc., enquanto a desmontagem do parafuso hexagonal deve usar uma chave especial, por isso n\u00e3o \u00e9 f\u00e1cil para o p\u00fablico em geral desmontar, o que tamb\u00e9m \u00e9 um benef\u00edcio.<\/p>

Apenas este problema de uma chave? Alguns clientes dizem que, como o parafuso hexagonal interno tem a vantagem de resist\u00eancia e \u00e9 projetado com orif\u00edcios escareados, \u00e9 dif\u00edcil desaparafusar em caso de escorregamento do fio, enquanto o parafuso hexagonal externo possui ferramentas comuns para faz\u00ea-lo, ent\u00e3o por que n\u00e3o projet\u00e1-lo em outras formas?<\/p>

Como voc\u00ea sabe, os parafusos hexagonais externos ficam expostos para fora, a chave deve ter um certo espa\u00e7o para aparafusar, o furo escareado necess\u00e1rio \u00e9 muito grande ou fica saliente. E o hexagonal precisa de um furo escareado bem pequeno, n\u00e3o leve em conta o espa\u00e7o, o hexagonal \u00e9 basicamente uma galinha. Portanto, o tipo de aplica\u00e7\u00e3o do parafuso, ou depende do uso da ocasi\u00e3o.<\/p>


Os parafusos de cabe\u00e7a hexagonal s\u00e3o semelhantes aos parafusos de cabe\u00e7a escareada, a cabe\u00e7a do prego \u00e9 enterrada na m\u00e1quina, a for\u00e7a de conex\u00e3o \u00e9 maior, mas deve usar as especifica\u00e7\u00f5es correspondentes da chave hexagonal para instalar e remover o parafuso. Geralmente usado em v\u00e1rias m\u00e1quinas-ferramentas e seus acess\u00f3rios.<\/p>

\u00a0De acordo com os requisitos de uso, existem v\u00e1rios pontos no desempenho:
1, a resist\u00eancia \u00e0 tra\u00e7\u00e3o nominal do material do parafuso at\u00e9 o n\u00edvel de 400MPa;
2, a taxa de resist\u00eancia ao escoamento do material do parafuso de 0,6; resist\u00eancia nominal do material do parafuso de 400 \u00d7 0,6 = grau 240MPa. Parafusos de alta resist\u00eancia de grau de desempenho 10.9, o material ap\u00f3s o tratamento t\u00e9rmico, pode alcan\u00e7ar:
a, a resist\u00eancia \u00e0 tra\u00e7\u00e3o nominal do material do parafuso at\u00e9 1000MPa.
b, a taxa de resist\u00eancia ao escoamento do material do parafuso de 0,9; resist\u00eancia nominal do material do parafuso de 1000 \u00d7 0,9 = grau 900MPa.<\/p>

\"Parafuso

O significado do n\u00edvel de desempenho dos parafusos hexagonais \u00e9 o padr\u00e3o internacional, o mesmo n\u00edvel de desempenho do parafuso, independentemente da diferen\u00e7a de material e origem, o desempenho \u00e9 o mesmo, o design s\u00f3 pode escolher o n\u00edvel de desempenho.<\/p>


PONTAS<\/p>


A grade dos parafusos de cabe\u00e7a cil\u00edndrica \u00e9 basicamente essa, as diferentes gradua\u00e7\u00f5es, o pre\u00e7o no mercado com certeza \u00e9 diferente. Os parafusos de cabe\u00e7a cil\u00edndrica de alta resist\u00eancia em geral s\u00e3o certamente muito mais altos do que o pre\u00e7o dos parafusos de cabe\u00e7a cil\u00edndrica comuns. No mercado geralmente usado mais ou 4,8 graus, 8,8 graus, 10,9 graus, 12,9 graus esses quatro tipos.<\/p>


Dica quente: Os parafusos de cabe\u00e7a hexagonal batem no exc\u00eantrico, batem no torto, podem levar a problemas muito s\u00e9rios. Por exemplo, pela apar\u00eancia do produto, o geral n\u00e3o \u00e9 bonito o suficiente. H\u00e1 tamb\u00e9m jogar exc\u00eantrico, \u00e9 f\u00e1cil levar ao soco da ferramenta de produ\u00e7\u00e3o f\u00e1cil de quebrar. Os mais graves tamb\u00e9m levar\u00e3o a parafusos hexagonais de cabe\u00e7a quebrada e uma s\u00e9rie de problemas.<\/p><\/div><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
