AI Technical Summary
During the forging process of TC18 titanium alloy, uneven deformation of the sidewalls and uneven temperature field of rod and beam forgings lead to unqualified microstructure and properties, making them prone to scrapping and causing economic losses.
Design a TC18 titanium alloy pre-forged rod-beam type, including through-type protrusions on the sidewalls and bottom of the pre-forged part, progressively decreasing protrusions on the sidewalls in the area perpendicular to the transverse ribs, and through-type protrusions on the bottom. Combine numerical simulation optimization design to ensure that the deformation is not less than 30%, and steps are designed at key positions to ensure accurate positioning.
It improves the uniformity of deformation of the forging sidewall, enhances the batch stability and forming quality of the forging, and meets the performance requirements of the final forging.
