Resumo
A Engenharia Reversa além de auxiliar na fabricação de um produto, acelera o desenvolvimento de um objeto já existente, sendo empregada para recuperar projetos e peças obsoletas ou simplesmente para produzir algo a um custo menor dentro do território nacional (redução de despesas com importações). É neste contexto que foi selecionado e desenvolvido o principal item de um rolo soldador que é o anel central (item de desgaste), utilizado em uma roldana de solda que é responsável por unir duas extremidades de embalagens metálicas através da solda por costura. Os métodos necessários para este desenvolvimento consistem na desmontagem, medição e modelagem computacional, acompanhada da lista de peças. Também foi realizada a identificação e caracterização do material da peça para a fabricação, remontagem do conjunto e testes em condições reais de funcionamento. Os resultados se mostram promissores, visto que foi possível realizar a modelagem do anel central, foco desta pesquisa, caracterizá-lo, selecionando um material de composição equivalente, que foi a liga de cobre, segundo a norma, EN 1652, CW103C. Além disso, foram registradas 8,96 milhões de embalagens soldadas, considerando 50% da vida útil do anel central fabricado com a nova liga de cobre, o que indica que o estudo foi satisfatório, pois ficou acima da média que foi de 16,196 milhões, considerando 100% da vida útil (registro de durabilidade dos últimos quatro discos de solda).
Reverse engineering apart from assisting the fabrication of a product, speeds up the development of an already existing object, being used to recover obsolete projects or parts or simply to manufacture something at a lower cost within the national territory (reduction of import costs). In this regard, it was selected and developed the main item of a welding roller that is its central ring (wear item), used in a welding sheave responsible for uniting two edges of a metal packaging through seam welding. The methods necessary for this development consist of disassembly, measurement, computational modeling, accompanied by the parts list. It was also performed the identification and characterization of the workpiece material for its fabrication, reassembly of the set, and test in real working conditions. The results are promising, given that it was possible to model the central ring, the main focus of this research, characterize it, and select an equivalent compositional material, that was the copper alloy, according to the standard EM 1692, CW103C. Moreover, 8,96 million welded packaging were registered considering 50% of the service life of the central ring manufactured with the new copper alloy, which indicates that the study was satisfactory, as it was above the average of 16.196 million, considering 100% of it’s service life (durability record of the last four welding rollers).
