Optimizing Die Life in Hot Forging: A Comprehensive Review of Improvement Methods

Abstract

Abstract: The wear investigation on die inserts utilized in the hot forging method to create a yoke type forging—an element that makes up passenger car steering systems—is presented in this paper. In order to provide a quick and accurate wear examination of the forging tools (of complex forms), the investigation used an innovative reverse scanning technique that eliminates the need to remove the tools from the producing unit. The study is based on evaluations (scans) of forgings that are routinely gathered from the process and serve as a practical tool for testing and characterization. Apart from the industrial bending process, a new lubrication-cooling system has been created to investigate the impact of lubrication quantity and duration on tool wear and to identify the best lubrication parameters to guarantee forging process repeatability. In additionally offering a new forging and stabilizing procedure for the lubricating and cooling devices, the preliminary results demonstrate the potential for employing an expanded method to study the lifespan of forging tools, including tools with tricky shape. The study's findings indicate that the inverse scanning approach allows for realistic real-time control over the forging tools' condition. Additionally, the apparatus is made to choose while offering the best tribological conditions for the procedure. Both of the suggested strategies ought to have a favorable effect on raising manufacturing output and lowering the cost of production.
