Abstract(s)
Uma das indústrias que mais tem evoluído e destacado nos últimos anos é a Indústria Automóvel. Sendo considerados para muitos como um meio de lazer ou uma ferramenta, o automóvel está presente nas vidas da maioria das pessoas em pleno século XXI. Derivado do seu papel, existe uma luta constante em busca de maior qualidade de fabrico, menores custos e tempos de ciclo para o fabrico das mais variadas peças, nomeadamente, peças de plástico.
No âmbito desta necessidade surge a obrigatoriedade de trabalhar estas peças, quer em vertente de projeto, como em vertentes mais práticas, como o corte. Esta dissertação destaca, desta forma, o trabalho desenvolvido para responder à necessidade da WRK, Lda, de reestruturar toda a solução existente de um equipamento de corte LASER cuja função é o corte de gitos de peças de plástico decorrentes do processo de injeção. Assim, a presente dissertação tem como objetivo demonstrar o desenvolvimento de um novo projeto
para a solução do equipamento de corte LASER, bem como apresentar, relacionar e quantificar todas as melhorias obtidas relativamente ao equipamento atual. Foi então conduzido um projeto de retrofit que englobou todos os sistemas presentes e necessários para que o equipamento funcione corretamente, desde a estrutura ao sistema de eixos. De forma a gerir o trabalho elaborado foi integrada na dissertação a metodologia Design Science Research (DSR). O resultado do trabalho foi a conceção de uma nova solução para um equipamento de corte de plástico por LASER mais robusto e mecanicamente fiável, cumprindo agora toda a legislação necessária em vigor. No projeto foram ainda maximizadas todas as aberturas para melhor
acesso ao interior da célula, bem como melhorado o sistema de estanqueidade ao redor do equipamento.
One of the industries that has evolved the most and stood out in the last couple of years is the automotive industry. Being considered by many as a leasure means or a tool, the automobile is present in most of the people´s lives in the XXI century. According to it's role, there is a constant struggle for high fabrication quality as well as lower costs and cycle times, namely for plastic parts. Within the scope of this need, arises the obligation of managing the fabrication of these parts, whether it is in a project matter or even in a more practical and specific way, such as the cut of the plastic. This dissertation outlines, this way, the developed work in response to the need of WRK, Lda to refurbish the present solution for a LASER cutting equipment whose function is to cut plastic sprues which are a product of the plastic injection process. Therefore, the present dissertation has as its main objective to layout the development of a new LASER cutting equipment project, as well as present, relate and quantify all the gathered improvements in comparison to the existing equipment. The retrofit project was then conducted and all the needed systems which allow the equipment to function correctly were taken into consideration, from the structure itself to the axle system. As a way of managing the elaborated work, it was followed the Design Science Research (DSR). This work resulted in the full conception of a new solution for a plastic cutting LASER equipment that is more robust and mechanically reliable, allied to the fact that it complies with the most recent legislation. All the opening of the equipment were maximized allowing better access to the inside of the cell, as well as the seal systems that were also improved around the whole equipment.
