摘要：

针对半开式弹簧卡扣相关产品生产制造中的冲压模具结构复杂、工艺废料多、尺寸一致性差以及开发周期长等问题，以半开式弹簧卡扣数控成形机构设计为例，结合线材自动成形机，开展成形工艺和机构设计相关研究。首先，对产品进行了全面分析，指出成形要求和成形过程中的难点。其次，研究并设计了半开式弹簧卡扣数控成形工艺步骤，并依据成形步骤设计了切断机构、折弯机构以及顶出机构。最后，经苏州兆能精密弹簧五金有限公司实际生产验证，设计的半开式弹簧卡扣数控成形机构不仅提高了产品的成形精度和生产效率，保证了产品的一致性，还节约了材料和时间，降低了生产成本，证明了半开式弹簧卡扣数控成形机构的可行性和实用性，为该技术的推广应用奠定了实践基础。

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.
