INFLUENCE OF TEMPERATURE AND DRAWING SPEED ON THE FORMING OF ALUMINUM ALLOY 1100 VIA WARMING HYDROFORMING PROCESS

Abstract

The limiting used of the alloys of aluminum since the formability is low at room temperature. To plan and grow more parts made of aluminum, new forming systems, for example, warm framing hydroforming and warming hydroforming processes have been explored to solve the low formability. The effect of temperature on the mechanical properties of aluminum 1100 sheet alloy is investigated at different temperature levels and strain rates using the test of uni-axial tensile. A warming forming tool for sheet metal is designed and manufactured. Four temperatures levels were used in this experiments (25 , 100 200 and 300 ). The drawing speeds that were used in these experiments were (3, 6, and 9 mm/min). Before design, the warming hydro-punch system, the analysis of this system is done in ANSYS software to choose the optimum die radius and then the results of experiments are simulated. The results of experiments showed that the appropriate hydroforming temperature and drawing speed of 1100 aluminum alloy are 300 and 3mm/min respectively. The FE simulation of strain distribution matched reasonably well with the experimental results.
