摘要
介绍了国内、外内高压成形的汽车管类零件对内高压成形生产汽车管类零件的特点及关键技术进行了分析。应用结果表明内高压成形生产汽车管类零件具有减小质量、节约材料20%～50%;减少零件数量和工艺装备数量;提高后续机械加工和组装焊接工作量;提高汽车零件性能(如强度、刚度及疲劳寿命);降低成本15%～30%等特点。
Automotive tubing parts at home and abroad by high internal high press forming was introduced. The characteristics and key technologies of internal high press forming to produce automotive tubing parts was analyzed. Practice indicated that to produce automotive tubing parts by internal high press forming process, 20%～50% materials as well as weight can be reduced, numbers both of parts and equipment can be reduced, parts properties, e.g. strength, stiffness and fatigue life, can be improved and 15%～30% costs can be saved.
