Stamping process analysis and progressive die design of l-panel for specific car seats

Abstract The frequent use of electric vehicle seats will lead to the loosening of their fixing devices, which will bring certain safety risks. This article studied the core component of the fixing device - L-panel, analyzed its forming process performance and focused on controlling the springback during its forming process, so as to prevent any issues related to low position accuracy when securing electric seats. Moreover, the die design was also carried out. A set of 8-station progressive dies was completed, which was of good precision, high production rate, good feasibility for mass production, good product interchangeability, and extremely high intelligent automation production.
