Research about Warm-Hot Forming Process Control of LTWB Auto B-Pillar

Abstract:

Article Preview

In recent years, with the trend of auto body lightweight, more and more auto manufacturers pay attention to warm-hot forming of laser tailor weld blank (LTWB). In this article, choosing Audi Q5 B-pillar as the study object provided by Benchmark 2008 and using the stamping specific software Autoform, the effects of blank holder force (BHF) and drawbead on the formability of B-pillar are studied in different forming tempreture and put forward the reverse compensation method to control the weld line offset and the reverse compensation quantity is quantized, which has great significance to direct the industrial production, determine the process parameters of warm-hot forming and reduce the times of trying dies.
