多股圆柱螺旋弹簧加工制造工艺技术

The Manufacturing Technique for Multi-radices Cylindrical Helical Springs

在分析零件结构的基础上,针对多股圆柱螺旋弹簧的加工特点,采用制作辅助工装的方法,使钢索缠制与弹簧成型一次完成,确保了弹簧的钢索索距、钢索索径及多股弹簧的外形尺寸要求。改变以往修整方式,采取定径强压后修整,提高了零件特性要求的制造工艺技术。通过试验和应用验证,效果良好。

Based on the analysis of the part structure and according to the processing characteristic of stranded wire cylindrical helical spring,the auxiliary fixture is manufactured to make the winding of steel wire and spring forming completed at once.Thus,ensure the accurate strand pitch and diameter of the steel wire and the dimension requirements of the stranded wire helical spring.The previous dressing method is changed and new manufacturing technology is used,performing dressing process after sizing and prestressing,and improving the parts performance requirement technology,achieve good effect though testing and validation.
