摘要：

首先介绍了用于加工精密轮廓零件的剪挤复合精整、平面压边精冲、齿圈压板精冲技术的特点，论述了精冲、冲压和精冲、挤压复合成形技术的工艺要点；针对具有塑性差和厚板的难成形坯料，介绍了对向凹模精冲、往复精冲和闭挤式精冲技术的工艺特点；展望了未来精冲技术的发展趋势，并指出未来精冲零件必向着更复杂、难成形方向发展，而对于新型精冲材料，精冲智能化、自动化技术也将在精冲行业中得到广泛应用。最后，提出了今后精冲技术的研究重点是有限元模拟、数字化设计、精冲辅助工艺和新型精冲的产业化问题等。

Firstly, it was introduced that the characteristics of the technologies used to process precise contour parts, including cutting-extruding trimming technology, fine blanking with plane blankholder and fine blanking with gear ring blankholder. The technical highlights of fine blanking, stamping and fine blanking, and combined extruding forming process were also analyzed. For materials with low plasticity and the thick plates that difficulty in forming, the technical characteristics of opposed die fine blanking, reciprocating fine blanking and closed extruding fine blanking were introduced respectively, and the future development tendency of fine blanking technology was prospected, which indicated that fine blanking parts would develop towards a more complex and difficult forming direction. Meanwhile, for the new fine blanking materials, intelligentization and automation technology of fine blanking would be extensively used in the industry. Finally, the research emphases of fine blanking technology were put forward, which would be FEM simulation, digitization design, fine blanking aided process and industrialization of new fine blanking.
