HB/Z 223.7-2003

Assembly workers and process engineers in aircraft manufacturing and maintenance use this standard to guide the riveting operations of swaged collar type rivets on metal structures. It ensures consistent and reliable riveting quality, which is critical for the safety and durability of aircraft structures.

飞机制造和维修企业的装配工人和工艺工程师使用本标准，用于指导金属结构件中环槽铆钉的铆接操作。该标准确保了铆接质量的一致性和可靠性，对飞机结构的安全性和耐久性至关重要。

This standard is Part 7 of the HB/Z 223 series, specifying the complete riveting process for swaged collar type rivets on aircraft metal structures, including two methods: pull riveting and upset riveting. It details each step from positioning and clamping, hole making, countersinking and chamfering, rivet insertion, to riveting and anti-corrosion treatment, along with tool requirements, quality control, and technical safety requirements. Appendix A adds special requirements for riveting titanium alloy swaged collar type rivets. This standard replaces the 1996 version and adds content such as riveting defect characteristics and elimination methods.
