预开卷机在预精焊生产中的应用

    Application of Coil Preparation Stand to Two-step Pipe Welding Process

    • 摘要: 介绍了预精焊机组中预开卷机的组成和结构特点、工作原理及过程,分析了钢卷头部尺寸精度对切斜量的影响。分析认为:侧弯量对切斜有较大影响,若将带钢“镰刀弯”控制在6 mm/5 m范围,可提高对头铣边速度,节省对头时间,提高产量。实际使用结果表明:该预开卷机工作可靠,能够很好的满足生产需要。

       

      Abstract: Described in the paper are the main aspects of the coil preparation stand integrated in the two-step pipe welding operation line, including equipment configuration and structure characteristics, and work principle and work process.Also analyzed is the effect by the dimensional accuracy of the head-end of the coil on the oblique cut amount.The analysis reveals that the side-bending amount imposes rather obvious effect on the oblique cut amount.In this case, if the bending range of the steel "sickle" is controlled within 6 mm/5 m, the butting-edge-milling speed shall be increased, and thus the butting time shall be shortened, and the output enhanced.The actual operation result shows that the coil preparation stand is capable of reliable operation, and is quite satisfactory to the need by the production.
