冲模结构术语
标签：凸模, 凹模, 导向柱, 卸料板, 模具术语
**凸模（punch）**为压制外形的上部刀具；**凹模（die）**为承受板料的下部型腔。**导向柱（guide pillar）**保证上下模对中；**卸料板（stripper）**在回程将板料从凸模脱开；**压边圈（blankholder）**在拉深时压制法兰防皱。复合模一次行程完成冲裁+成形。
The **punch** is the upper tool that shapes the outline; the **die** is the lower cavity receiving the sheet. The **guide pillar** keeps the tool halves aligned; the **stripper** releases the sheet from the punch on return; the **blankholder** clamps the flange during drawing to prevent wrinkles. A compound die cuts and forms in one stroke. ---
