Abstract(s)
Na Indústria Automóvel, e em todas as outras indústrias ligadas a esta, sente-se cada
vez mais, um aumento da competitividade e da obrigatoriedade de cumprir requisitos
a nível ambiental. Tendo isto em conta, os esforços para aumentar o tempo de vida útil
dos seus produtos são maiores do que nunca.
A presente dissertação foi desenvolvida em torno desta necessidade real, procurando
reunir informação que permita obter um aumento do tempo de vida útil dos punções
de cravação de terminais elétricos para a Indústria Automóvel. O processo para atingir
o objetivo do trabalho prático iniciou-se pela recolha de amostras dos principais
concorrentes da Ricardo & Barbosa no mercado, de modo a ser possível fazer uma
análise e caracterização das mesmas. Posteriormente, realizaram-se sessões de
brainstorming, onde se definiu que amostras alternativas se iriam produzir, analisar e
caracterizar. Mais tarde, foram produzidas novas ferramentas de cravação em
diferentes etapas da produção, de forma a estudar a importância e impacto das etapas
de acabamento do processo produtivo. Finalmente, foram produzidas novas amostras,
colocadas em teste num cliente da R&B e realizados ensaios de caracterização
avançados, o que permitiu uma melhor compreensão da evolução do desgaste das
ferramentas durante o seu tempo de vida útil.
Em suma, a presente dissertação contribuiu para uma melhor clarificação do tempo de
vida útil das ferramentas de cravação da R&B, possibilitando identificar potenciais
indícios de desgaste e, consequentemente, garantir uma melhor qualidade dos seus
punções de cravação
In the Automotive Industry, and in all other industries linked to it, an increase in competitiveness and the obligation to comply with environmental requirements is increasingly felt. Efforts to increase the lifespan of the products are greater than ever. This dissertation was developed around this real need, seeking to gather information that allows an increase in the lifespan of electrical terminal crimping tools for the Automotive Industry. The process to achieve the objective of the practical work began with the collection of samples from the main competitors of Ricardo & Barbosa in the market, to be able to analyze and characterize them. Subsequently, brainstorming sessions were carried out, where it was defined which alternative samples would be produced, analyzed, and characterized. Later, new crimping tools were produced at different stages of production, to study the importance and impact of the finishing stages of the production process. Finally, new samples were produced, put to the test at an R&B customer and advanced characterization tests were done, which allowed a better understanding of the evolution of tool wear during its lifetime. In conclusion, the present dissertation contributed to a better clarification of the lifespan of R&B's crimping tools, making it possible to identify potential signs of wear and, consequently, guarantee a better quality of their crimping punches
