小直径焊管管端修磨头设计

Pipe End Grinding Head Design for Small Diameter Welded Pipe

针对目前行业内采用的传统修磨机无法满足小直径焊管管端自动内修磨的问题,设计了一种适用于小直径螺旋焊管管端内修磨磨头。该设计对修磨机的磨头机构进行了重新布局,使用单轮结构代替原来的双轮结构,并去除原先的偏摆机构等,对传统磨头进行简化。同时制作了样机,进行了相关试验,试验结果证明了该设计方案可以较好地解决小直径钢管的管端修磨问题,同时与原来的磨头机构不冲突,对修磨大直径钢管也是一种很好的补充方法,可以在制管生产线上广泛应用。

The traditional grinding machine, commonly used in industry at present, cannot solve automatic grinding for small diameter welded pipe end, so a kind of pipe end grinding head was designed for small diameter SAWH pipe end. The design relayout the grinding mechanism of grinding machine, using a single round structure to replace the original double round, removing the original yawing mechanism, simplifying the traditional grinding head. A sample was made, and the relevant tests were carried out, the experimental results verified this design scheme can better solve pipe end grinding for small diameter steel pipe, does not conflict with the original grinding head organization at the same time, which is a good supplementary method for large diameter steel pipe grinding, can be widely used in pipe-making production line.
