Diagnóstico de uma prensa extrusora de alumínio

Abstract

It is clear that in recent years, technological advances and the modernization of industrial processes have been essential for economic and social development. In this context, the interaction between workers and machines must present an effective management of occupational safety and healty, and comply with the current legislation. The extrusion process of aluminum profiles is carried out by extruder presses, wich are machines that can generate risks to the health and safety of workers, and therefore must comply with standardization standards. The types of research used in this work are bibliographical, field and qualitative. The objectives of this study are to perform a diagnostic, categorising and a risk analysis of an aluminum extruder press, based on Regulatory Standard – NR 12, ABNT NBR ISO 12100:2013, ISO/TR 14121-2:2012 and ABNT NBR ISO 14153:2013. The diagnostic is elaborated from a photographic register, the press and its set, and the identification of nonconformities. From the diagnostic, the risk analysis and the categorising and, afterwards, the considerations and proposed measures of control are made. For the risk analysis the “GFOP” method is applied, based on identified hazards (burn; fall; electric shock; crushing; and mutilation). However, through categorising, category 4 is defined, with its due specifications. With the results obtained, this work contributes to solving management problems and preserving the physical integrity and life off all workers, as well as others involved in the work aluminum extrusion process.
