摘要
为了提高螺旋预焊机组铣边质量及效率,结合螺旋预精焊钢管预焊生产工艺特点,系统分析了预焊机组带钢递送速度快、带钢边沿铣削加工量大及带钢弯度等因素对铣边质量的影响,提出了可行的控制措施和解决办法。对铣边工艺及装备进行了优化设计,采用"三铣边工艺",合理分配铣削加工量,有效保证了带钢边沿坡口和钝边等质量指标的加工稳定性,为提高预焊钢管成型及预精焊质量奠定了基础。实际应用表明,效果明显,可满足高速预焊生产的铣边要求。
In order to increase the edge milling quality and efficiency of spiral prewelding unit, combined with prewelding characteristics of SAWH pipe, it systematically analyzed the influence on edge milling quality of several factors, such as strip steel fast delivery of the prewelding unit, large amount of machining for strip steel edge milling, the strip steel camber and so on. It also put forward the feasible control measures and solutions： the optimization design was conducted for edge milling technology and equipment, ＂three edge milling process＂was adopted and carried out, and reasonable distribution for milling processing capacity. These measures effectively guaranteed the machining stability of quality index, including the edge groove of strip steel, truncated edge, etc, which laid a solid foundation for improving the prewelding pipe forming weld and pre-finishing welding quality. Actual application showed that its effect is obvious, can meet the requirements of high speed milling in the process of the welding production.
