Os pun\u00e7\u00f5es de metal duro s\u00e3o um dos principais componentes usados em v\u00e1rios processos de fabrica\u00e7\u00e3o, especialmente em ind\u00fastrias como estampagem e corte de chapas met\u00e1licas. O pun\u00e7\u00e3o de carboneto de tungst\u00eanio \u00e9 usado com uma inser\u00e7\u00e3o de matriz em conjunto como um pun\u00e7\u00e3o completo e um conjunto de matrizes.<\/p>\n\n\n\n

Eles s\u00e3o feitos de metal duro, \u00e9 claro, e \u00e0s vezes s\u00e3o feitos de PM ou HSS. Mas o metal duro \u00e9 a melhor escolha, pois \u00e9 um material met\u00e1lico duro conhecido por sua dureza, resist\u00eancia ao desgaste e durabilidade. Existem v\u00e1rios tipos de marcas e modelos de metal duro, como Fujilloy, Sanalloy, Everloy, Cbceratizit, etc. Alguns modelos de metal duro comumente usados s\u00e3o KD20, RD50, KX03, RG3, FD15, FD25, GA20, H40S e CD650, etc.<\/p>\n\n\n\n

Let\u2019s see some of the key features and applications of carbide punches:<\/p>\n\n\n\n

Recursos de pun\u00e7\u00f5es de metal duro<\/h2>\n\n\n\n

Dureza:<\/a><\/h3>\n\n\n\n

Os pun\u00e7\u00f5es de metal duro s\u00e3o extremamente duros e podem suportar aplica\u00e7\u00f5es de alta press\u00e3o sem deformar ou quebrar. Essa dureza os torna ideais para uso em opera\u00e7\u00f5es de puncionamento onde \u00e9 necess\u00e1ria uma ferramenta afiada e dur\u00e1vel.<\/p>\n\n\n\n

Resist\u00eancia ao desgaste:<\/h3>\n\n\n\n

Os pun\u00e7\u00f5es de metal duro t\u00eam excelente resist\u00eancia ao desgaste, o que significa que mant\u00eam sua nitidez e precis\u00e3o dimensional mesmo ap\u00f3s uso prolongado. Esta propriedade prolonga a vida \u00fatil da ferramenta e reduz a necessidade de substitui\u00e7\u00f5es frequentes.<\/p>\n\n\n\n

Precis\u00e3o:<\/h3>\n\n\n\n

Os pun\u00e7\u00f5es de metal duro podem ser fabricados com alta precis\u00e3o, garantindo resultados consistentes e precisos nas opera\u00e7\u00f5es de puncionamento e conforma\u00e7\u00e3o. Esta precis\u00e3o \u00e9 crucial em ind\u00fastrias onde s\u00e3o necess\u00e1rias toler\u00e2ncias rigorosas.<\/p>\n\n\n\n

Custo-benef\u00edcio:<\/h3>\n\n\n\n

Embora os pun\u00e7\u00f5es de metal duro possam ter um custo inicial mais alto em compara\u00e7\u00e3o com materiais de ferramentas tradicionais, sua durabilidade e desempenho geralmente resultam em economia de custos a longo prazo. A redu\u00e7\u00e3o do tempo de inatividade e dos custos de substitui\u00e7\u00e3o de ferramentas contribui para a sua rela\u00e7\u00e3o custo-benef\u00edcio geral.<\/p>\n\n\n\n

Aplica\u00e7\u00f5es de pun\u00e7\u00f5es de metal duro<\/h2>\n\n\n\n

Os pun\u00e7\u00f5es de metal duro podem ser usados com uma variedade de materiais, incluindo metais, pl\u00e1sticos, cer\u00e2micas e comp\u00f3sitos. Eles s\u00e3o usados para tarefas como puncionamento, estampagem, conforma\u00e7\u00e3o e modelagem de materiais.<\/p>\n\n\n\n

Eles s\u00e3o adequados para puncionar chapas met\u00e1licas, fazer furos, formar formas, estampar e outras tarefas semelhantes em diferentes materiais.<\/p>\n\n\n\n

Eles s\u00e3o componentes essenciais de ferramentas em muitos processos de fabrica\u00e7\u00e3o. Principalmente no processo de fabrica\u00e7\u00e3o de microeletr\u00f4nica. Por exemplo, microconectores e microblocos de terminais, componentes de celulares e computadores, etc.<\/p>\n\n\n\n

Tipos de pun\u00e7\u00e3o de metal duro<\/h2>\n\n\n\n

Existem v\u00e1rios tipos de pun\u00e7\u00f5es de metal duro. De acordo com a classifica\u00e7\u00e3o do formato, alguns s\u00e3o pun\u00e7\u00f5es cil\u00edndricos de metal duro, outros s\u00e3o pun\u00e7\u00f5es retangulares e quadrados.<\/p>\n\n\n\n

Existem algumas marcas de pun\u00e7\u00f5es padr\u00e3o, como pun\u00e7\u00f5es de metal duro Dayton, pun\u00e7\u00f5es de metal duro Misumi, pun\u00e7\u00f5es de metal duro vital\u00edcias e conjuntos de matrizes. Mas a maioria dos pun\u00e7\u00f5es s\u00e3o feitos sob medida de acordo com projetos e desenhos espec\u00edficos.<\/p>\n\n\n\n

Esses tipos de pun\u00e7\u00e3o personalizados podem ser chamados conforme abaixo:<\/p>\n\n\n\n

Pun\u00e7\u00f5es em metal duro<\/p>\n\n\n\n

Pun\u00e7\u00f5es formadoras de metal duro<\/p>\n\n\n\n

Pun\u00e7\u00f5es para estampagem de metal duro<\/p>\n\n\n\n

Pun\u00e7\u00f5es retas de metal duro<\/p>\n\n\n\n

Pun\u00e7\u00f5es de cunhagem de metal duro<\/p>\n\n\n\n

Pun\u00e7\u00f5es perfurantes de metal duro<\/p>\n\n\n\n

Pun\u00e7\u00f5es piloto de metal duro<\/p>\n\n\n\n

Pun\u00e7\u00f5es de metal duro para retifica\u00e7\u00e3o de perfis<\/p>\n\n\n\n

Defici\u00eancias dos pun\u00e7\u00f5es de metal duro<\/h2>\n\n\n\n

Embora o pun\u00e7\u00e3o de metal duro tenha algumas boas caracter\u00edsticas, ele tamb\u00e9m apresenta alguns pontos fracos. Como \u00e9 muito duro, a dureza pode ficar em torno de 89-95 HRC. N\u00e3o \u00e9 f\u00e1cil de processar, basta usar equipamentos de usinagem muito caros para processar o material, por exemplo, retifica\u00e7\u00e3o de perfis e retifica\u00e7\u00e3o de superf\u00edcie com rodas diamantadas de boa qualidade, ou EDM com corte de fio ou EDM Sinker. Portanto, seu custo de material e custo de fabrica\u00e7\u00e3o s\u00e3o altos.<\/p>\n\n\n\n

H\u00e1 outro ponto fraco: ele pode ser facilmente danificado ao cair no ch\u00e3o. Embora seja duro, tamb\u00e9m \u00e9 crocante e f\u00e1cil de quebrar. Ent\u00e3o o pacote \u00e9 muito importante. Geralmente \u00e9 embalado em uma caixa pl\u00e1stica com algod\u00e3o perolado e tamb\u00e9m fixado com fita de papel.<\/p>\n\n\n\n

Pun\u00e7\u00f5es e matrizes de metal duro<\/h2>\n\n\n\n

Como mencionamos acima, pun\u00e7\u00f5es e matrizes de metal duro s\u00e3o um conjunto de ferramentas usadas em conjunto. As matrizes aqui significam as inser\u00e7\u00f5es da matriz de metal duro com furos que combinam exatamente com os pun\u00e7\u00f5es de metal duro. Normalmente, uma inser\u00e7\u00e3o de matriz precisa reter uma folga, um \u00e2ngulo de inclina\u00e7\u00e3o e um \u00e2ngulo c\u00f4nico em alguns lugares para garantir o uso adequado.<\/p>\n\n\n\n
