车身覆盖件拼焊板冲压成形技术的研究现状及发展趋势

摘要

The characteristics and developing history of stamping technology used for auto-body panels were introduced briefly. The newest development and existing problems were presented from the welding materials, welding technologies, and also research methods and key technologies in the forming process of tailor welded blanks(TWBs). In the end, the development trends of TWBs stamping technology was identified.%简述了汽车车身覆盖件拼焊板冲压成形技术的特点与发展历史;从拼焊板材料与焊接技术、拼焊板冲压成形的研究手段和面临的几个关键问题等方面阐述了有关拼焊板研究和应用的最新成果;探讨了拼焊板冲压成形技术的发展趋势.
