Modelagem e construção de dispositivos para a soldagem dos quadros centrais de um protótipo de pulverizador agrícola

Abstract

The brazilian agricultural scene demands the development of high technology equipments and implements. In this context, self-propelled machines for pesticide application gain more prominence. The present project consisted of the development of fixtures for the welding of the só called ‘Central Frames’ from an agricultural sprayer. A methodology was structured for the project execution based on the theoretical references connected to product project methodologies and welding fixtures. The execution of the project started with the study of the 3D Models from the frames, followed by the definition of welding configurations and the modelling of the suggested solutions. The fixtures were fabricated, and with the aid from welding procedures, guided the welding of the components. The manufacturing of the central frames with the developed solution – defined by a modular setup of welding fixtures – was approved by the company’s quality department, which indicates that the process of fixtures development presented can be utilized succesfully in similar welded structures.
