摘　　要：分析了汽车坐垫边梁侧件相应区域与衬套铆接配合的技术要求,还介绍了常规侧件连接处的生产工艺和特点,指出目前存在的问题和缺陷。通过结合材料流动规律和体积不变定律,优化并整合新工序,有效解决了边梁侧件连接处侧壁过薄、配合稳定性差的问题。结合实际生产,证明了整体工序设计合理,有效控制了成本,满足了客户的使用要求。It analyzed the technical requirements for the riveting fit between the corresponding ar-eas of the side members of the car seat cushion and the bushing,and introduced the production process and characteristics of the conventional side member connection,pointed out the existing problems and defects.By combining the laws of material flow and volume conservation,improving and optimizing new processes,and integrating new processes,the problems of thin side walls and poor fit stability at the junction of side beams were effectively solved.Based on actual production,it had been proven that the overall process design was reasonable,and the cost control was appro-priate,which met the customer's usage requirements.
