A substitui\u00e7\u00e3o de um pun\u00e7\u00e3o gasto \u00e9 normalmente considerada uma opera\u00e7\u00e3o de rotina.<\/p>\n\n\n\n

Mas na estampagem de precis\u00e3o, muitos engenheiros j\u00e1 passaram por isso:<\/p>\n\n\n\n

\u00c9 instalado um novo pun\u00e7\u00e3o, as dimens\u00f5es est\u00e3o dentro da toler\u00e2ncia - mas o desempenho altera-se.<\/p>\n\n\n\n

As rebarbas aumentam. A vida da ferramenta torna-se imprevis\u00edvel. A lascagem da aresta aparece mais cedo do que o esperado.<\/p>\n\n\n\n

Porqu\u00ea?<\/p>\n\n\n\n

Porque a substitui\u00e7\u00e3o de pun\u00e7\u00f5es n\u00e3o tem apenas a ver com dimens\u00f5es.<\/p>\n\n\n\n

Trata-se de consist\u00eancia geom\u00e9trica<\/strong>.<\/p>\n\n\n\n

Pequenas diferen\u00e7as de geometria, grande impacto na produ\u00e7\u00e3o<\/h2>\n\n\n\n

Em aplica\u00e7\u00f5es de alta precis\u00e3o, especialmente em matrizes progressivas e estampagem de conectores, mesmo varia\u00e7\u00f5es microsc\u00f3picas podem afetar todo o processo.<\/p>\n\n\n\n

\n

Alguns micr\u00f3metros de desvio:<\/p>\n\n\n\n

<\/path><\/svg>Perfil de perfura\u00e7\u00e3o<\/span><\/div>
<\/path><\/svg>Raio da borda<\/span><\/div>
<\/path><\/svg>Zonas de transi\u00e7\u00e3o<\/span><\/div><\/div>\n\n\n\n

pode alterar a forma como o material flui durante a estampagem.<\/p>\n\n\n\n

Isto conduz frequentemente a:<\/p>\n\n\n\n

<\/path><\/svg>Isto conduz frequentemente a:<\/span><\/div>
<\/path><\/svg>Qualidade inconsistente das pe\u00e7as<\/span><\/div>

\n
\"\"<\/figure>\n<\/div>\n <\/div><\/div>\n\n\n\n

Dois pun\u00e7\u00f5es podem parecer id\u00eanticos no papel, mas comportam-se de forma muito diferente na produ\u00e7\u00e3o.<\/p>\n\n\n\n

Porque \u00e9 que a retifica\u00e7\u00e3o de perfis faz a diferen\u00e7a<\/h2>\n\n\n\n

\u00c9 aqui que a retifica\u00e7\u00e3o de perfis se torna cr\u00edtica.<\/p>\n\n\n\n

N\u00e3o se trata apenas de obter toler\u00e2ncias apertadas, mas de garantir que todos os pormenores da geometria do pun\u00e7\u00e3o s\u00e3o repet\u00edveis.<\/p>\n\n\n\n

Os principais factores incluem:<\/p>\n\n\n\n

<\/path><\/svg>Raio de borda controlado para distribui\u00e7\u00e3o de tens\u00f5es<\/span><\/div>
<\/path><\/svg>Zonas de transi\u00e7\u00e3o suaves para reduzir a concentra\u00e7\u00e3o de tens\u00f5es<\/span><\/div>
<\/path><\/svg>Replica\u00e7\u00e3o exacta do perfil para um comportamento de corte consistente<\/span><\/div><\/div>\n\n\n\n

Sem uma consist\u00eancia de retifica\u00e7\u00e3o est\u00e1vel, mesmo os materiais de alta qualidade e um tratamento t\u00e9rmico adequado n\u00e3o podem garantir o desempenho.<\/p>\n\n\n\n

O que os engenheiros realmente precisam<\/h2>\n\n\n\n

Do ponto de vista da produ\u00e7\u00e3o, um \u201cbom pun\u00e7\u00e3o sobresselente\u201d n\u00e3o \u00e9 apenas aquele que serve.<\/p>\n\n\n\n

\u00c9 uma que:<\/p>\n\n\n\n

<\/path><\/svg>Tem o mesmo desempenho que o original<\/span><\/div>
<\/path><\/svg>Mant\u00e9m a vida \u00fatil da ferramenta est\u00e1vel<\/span><\/div>
<\/path><\/svg>N\u00e3o introduz novas vari\u00e1veis no processo<\/span><\/div><\/div>\n\n\n\n

Este n\u00edvel de consist\u00eancia requer n\u00e3o s\u00f3 equipamento de precis\u00e3o, mas tamb\u00e9m experi\u00eancia no controlo da geometria a um n\u00edvel micr\u00f3nico.<\/p>\n\n\n\n

Como apoiamos o desempenho consistente da perfura\u00e7\u00e3o<\/h2>\n\n\n\n

No nosso trabalho com aplica\u00e7\u00f5es de estampagem de precis\u00e3o, concentramo-nos em:<\/p>\n\n\n\n

<\/path><\/svg>Retifica\u00e7\u00e3o de perfis de alta precis\u00e3o<\/span><\/div>
<\/path><\/svg>Controlo rigoroso da geometria das arestas e das transi\u00e7\u00f5es<\/span><\/div>
<\/path><\/svg>Consist\u00eancia entre lotes para um desempenho repet\u00edvel<\/span><\/div><\/div>\n\n\n\n

Isto \u00e9 especialmente importante para os pun\u00e7\u00f5es de metal duro utilizados em ambientes de alta velocidade ou de carga elevada<\/p>\n\n\n\n

Replacing a worn punch is usually considered a routine operation. But in precision stamping, many engineers have experienced this: A new punch is installed, dimensions are within tolerance \u2014 yet performance changes. Burrs increase.
