Análise do planejamento e desenvolvimento de uma máquina expansora de tubos

Abstract

Machines and tools that assist in the mechanical conformation process are present in most metal-mechanical industries and aim to change the material's geometry through applied forces. Due to the need for machinery to expand tubes with low amount invested, a machine was planned and developed using a simple hydraulic system and tooling in order to be durable and functional. The present work aims to analyze the planning and development of a tube expander machine, used in the metal-mechanical industry for the production of hundreds of parts per day. First, an analysis of the material used in the mechanical conformation will be carried out, so, it is possible to evaluate what the hydraulic project for the machinery should be. In a second moment, the evaluation of the structural part will be carried out, aiming at a compact and robust machine that occupies the least space possible in the environment and supports the effort exerted when shaping the material. After completing these two steps, the planning and development of the necessary tooling to carry out the expansion of the tubes will be carried out, and finally, show the results obtained during the process.
