Process innovation in advanced sheet metal manufacturing

世界汽车制造商在深拉深后的修边过程中报废了50%的金属板材。这种浪费主要是由于材料被保持在压边架中，这有助于控制撕裂和起皱失效之间的过程窗口。该项目的目的是开发一种新的工艺，可以在没有压边架的情况下形成深拉形状。为了评估工艺，将设计和开发新机器的工具，并研究各种形状和材料。将提出分析模型来了解其局限性；最终导致开发一个完全自动化的工业演示过程。

The world's automotive manufacturers scrap 50% of all sheet metal during the trimming process after deep-drawing. This waste is mainly a result of material being held in the blankholder, which helps the control process window between tearing and wrinkling failures. The aim of this project is to develop a novel process that can form deep-drawn shapes without the blankholder. In order to evaluate the process, tooling of a new machine will be designed and developed and various shapes and materials will be investigated. Analytical models will be proposed to understand its limits; ultimately leading to the development of a fully automated industrial demonstrator process.
