ESTAMPO DE CORTE: estudo comparativo de punção e matriz de aço SAE 1045 e aço VC131 com tratamento térmico conforme descrição do fabricante, para estampagem de aço SAE 1012 com espessura de 3mm e diâmetro de 32,5mm

Abstract

This work addresses the issue of the use of steel for cold working and steel of mechanical construction for the same purpose. It specifically deals with VC131 steel and SAE 1045 steel in the stamping of SAE 1012 steel parts with determined thickness and diameter. It then describes the entire theoretical basis and subsequent practical tests and analysis of results, indicating the ideal way for heat treatment according to manufacturers' standards, as well as the best application for cutting tools (stamp) in the manufacturing process of products with 3mm thickness and diameter of 32.5mm. Through this research, it was possible to prove the impracticability of SAE 1045 steel for stamping, demonstrating that early wear and cost, not of the raw material, but of equipment and labor, becomes expensive before use.
