AUTOMAÇÃO PNEUMÁTICA NO PROCESSO DE GRAMPEAMENTO DE CAIXAS DE MOLDES EM AREIA VERDE

Abstract

Metallurgy is the science that studies and manages metals from their extraction from the subsoil to their transformation into products suitable for use, it designates a set of procedures and techniques for the extraction, manufacture, casting and treatment of metals and their alloys. The work consists of a case study carried out in a metallurgical industry that operates in the casting segment in green sand molds, in this process boxes formed by pairs are used, which are respectively cover and bottom and are manually stapled. This monograph aims to demonstrate how pneumatic automation can assist in the creation of an automated system for the stapling of these mold boxes in green sand since the process is done manually and two operators are used who work between the moving boxes increasing the risk of accident of the work in the company, the objective will be to automate this function through the use of pneumatic actuators with the purpose of reducing costs of the manufactured product, improving the efficiency of the stapling reducing the index of scrap and eliminating the risks of accidents of the work, therefore, they will be removed of this sector and consequently of the payroll expenses with labor, reducing the direct costs in my finished product. After the entire project was executed, it was concluded that the system implementation was satisfactory, since with a low investment a good return and a good profitability were obtained.
