Otimização do processo de fabricação da pá da amassadeira

Abstract

The objective of this work is to optimize the manufacturing process of a part that composes a mixer (product manufactured by G.Paniz), called mixing paddle. This part is made of nodular cast iron FE 42012 and needs to go through a process of sandblasting, polishing and tin bath. All the development has as premise the use of the analytical method, using concepts from the available literature and, as a complement, the use of finite element analysis computational simulations. The present study starts from the need to reduce the product cost in order to make it more competitive in the market. For the analysis of the critical component, a static simulation was used the von Mises stress as a criterion, thus it was possible to evaluate the points of higher stress concentration and if they would not exceed the yield strength of the material. The use of the analytical model with the aid of simulation aims to determine whether the project is technically, commercially, and financially viable. In the second moment a sample manufactured in cast aluminum SAE 306 was fabricated for validation in practice.
