近年来，由于我国对于工业标准的提升，对连续管型材料的要求也逐渐的提高，对连续直缝焊管的焊缝打磨要求也提升到了一个新的高度。由于传统的直缝焊管的焊缝打磨设备为砂带横向打磨，即通过将砂带横向跨过需要打磨的连续直缝焊管物料，然后通过砂带的连续运动实现砂带对直缝焊管物料的打磨工作，这样的结构会使砂带的运动力施加在连续直缝焊管物料上，从而使连续直缝焊管物料在被打磨的同时发生偏载，这会使焊缝的打磨与实际需要的打磨效果出现偏差，这对于高精度管材来讲是致命的缺陷，所以本领域的技术人员为了解决这样的技术问题开发一种既可以实现砂带的连续打磨又不会使砂带产生作用于连续直缝焊管物料的偏载力的一种焊缝打磨装置成为了行业的需要。In recent years, due to the improvement of my country's industrial standards, the requirements for continuous tubular materials have also gradually increased, and the requirements for weld grinding of continuous longitudinal welded pipes have also been raised to a new height.

Therefore, in order to solve such technical problems, those skilled in the art have developed a method that can realize the continuous grinding of the abrasive belt without causing the abrasive belt to act on the continuous straight line. A weld seam grinding device that can reduce the eccentric load of seam welded pipe materials has become the need of the industry.
