摘要：以某車型全景天窗頂蓋為例，通過對零件結構進行分析，介紹了全景天窗頂蓋沖壓工藝，設計了 用于成形全景天窗口部特征的側整形模，并闡述了2種雙動斜楔機構在全景天窗頂蓋側整形模中的應 用。實際應用表明，凹模擴張斜楔機構與凹模收縮斜楔機構的聯合使用，使模具機構更加緊湊和穩定， 實現了全景天窗口部沿周負角法蘭的同步成形，減少了成形工序，降低了零件制造成本。

Abstract: Taking a panorama sunroof panel as an example, the stamping process was described based on analysis of part structure, and a side sizing die was designed for panorama sunroof flang? ing area forming. It focused on the application of two dual driving wedge in the die design. The practical application showed that the die structure could be designed compactly and steadily by combined utilizing the die expanding wedge and die shrinking wedge, the forming of panorama sunroof flanging area could be synchronized.
Key words: roof panel; panorama sunroof; stamping process; die structure; dual driving wedge
