摘　　要：连杆采用涨断加工是国际上近年发展起来的一种连杆加工新技术,但连杆涨断后爆口一直是涨断连杆的最大问题,文章从激光涨断加工工艺、材料试验等角度详细分析了连杆爆口产生的原因,得出S含量低于材料标准要求是产生爆口的关键因素,从而为降低涨断连杆的工废率和生产成本提供指导意见。Cracking is a new technology recently developed internationally for connection rod machining. But after the connection rod is cracked, the biggest problem is many separated surfaces, this paper analyzes the reason why separated surface occur from the view point of laser cracking machining process, material test etc. It indicates that low S content is the key factor causing separated surface, thus providing guidance to the reduction of both production cost and reject rate of the cracking connection rod.
