高频直缝焊管内毛刺清除装置设计改进

Improvement of HF Longitudinal Welded Pipe Inside Burr Removing Device

介绍了高频直缝焊管内毛刺清除的主要方式,对天津双街钢管有限公司准325 mm机组原有机械刮削式内毛刺清除装置的结构形式及优缺点进行了分析。研究设计了新型液压升降刮削式内毛刺清除装置,对其周向调整结构、无油润滑轴承、刀具冷却方式和内毛刺余高检测方法等创新点进行了详细的阐述。经过实际生产应用,这种新型液压升降式内毛刺清除装置刮削质量更稳定,轴承套和刀具的使用成本更低,操作方便,经济实用,在高频直缝焊管生产行业中有很好的推广价值。

The main removing insdie burr methods on high frequency longitudinal welded pipe were introduced;the structure,advantages and disadvantages of original mechanical scraping inside burr removing device of 325 units in Tianjin Shuangjie Steel Pipe Co.,Ltd.were analyzed.A new kind of hydraulic lifting and scraping inside burr removing device was designed and studied,and several innovative points were expatiated,covering the circumferential adjusting structure,bearing without oil lubrication,cutter cooling mode,detecting method of inside burr reinforcement and so on.The practical application proved that this new device possesses stable quality,lower cost for bearing and cutter,operation convenience,so it is applicable to widely promote in high frequency longitudinal welded pipe industry.
