Abstract：

In response to the problems of complex stamping die structure, high process waste, poor dimensional consistency and long development cycle in the production and manufacturing of semi-open spring buckle related products, for the computer numerical control(CNC) forming mechanism design of semi-open spring buckle, combined with wire automatic forming machine,the research on forming process and mechanism design were conducted. Firstly, a comprehensive analysis was conducted, which pointing out the forming requirements and difficulties in the forming process. Secondly, the CNC forming process steps of semi-open spring buckle were studied and designed. Furthermore, based on the forming steps, the cutting, bending and ejection mechanisms during the forming process were designed. Finally, the actual production testing was realized by Suzhou Zhaoneng Precision Spring Hardware Co., Ltd. The results show that the designed CNC forming mechanism for semi-open spring buckle not only improves the product forming accuracy and production efficiency, ensures the product consistency, but also saves the materials and process time and reduces the production costs, which proves the feasibility and practicality of the CNC forming mechanism for semi-open spring buckle, and lays a practical foundation for the promotion and application of this technology.
