Troubleshooting: Wrinkling, Cracking
常见问题：起皱、开裂
标签：起皱, 开裂, 故障排查
①起皱：坯料未贴模、进给过快或材料过薄→先充分收口、放慢、加厚料。②开裂：加工硬化未退火或模板有尖角→及时退火、圆滑过渡。③壁厚不均：压力偏心→保持工具-模板平行、圆周均匀施压。④橘皮：局部过热/过压→降速降温。
①Wrinkling: blank not set, too-fast feed, or too thin → set the edge fully, slow down, thicker stock. ②Cracking: no anneal or sharp mandrel → anneal in time, round transitions. ③Uneven wall: eccentric pressure → keep tool parallel to mandrel, even force. ④Orange peel: local overheat/pressure → slower, cooler. ---
