Prediction of Springback and Die Compensation in TC4 Alloy Blade Forging Based on the Finite Element Method
Author Information
Abstract
The finite element simulation method was employed to simulate the forging process of TC4 alloy blades, predicting the post-forging springback of the blades. Based on the springback data, compensation was applied to the blade forging die, and simulation experiments were conducted using the compensated die to analyze the effectiveness of springback compensation. The results indicate that the springback amount of each cross-section of the TC4 alloy blade increased with the distance from the tenon after forging. When the distance reaches 122 mm, the springback angle at that cross-section reaches 2.2°. After implementing reverse equal-amount springback compensation, most of the blade’s springback was eliminated, with residual springback of 0.2°–0.4° observed in cross-sections at distances ≥112 mm.
