The shape modulating machine for the large-diameter oil & gas pipeline is the main component of the automatic welding equipment of oil & gas pipelines, and is mainly used for pipe processing groove at the construction site. The groove quality of the pipe end directly affects the difficulty and quality of automatic welding. Engineering application shows that one of the main factors affecting the quality of pipe groove processing is the mechanical vibration of the shape modulating machine. Taking the CPP900-FM4048 shape modulating machine produced by Pipeline Science Research Institute Co., Ltd as the research object of the study, analyzing the vibration test under different working conditions, finding out the main vibration source and analyzing the cause of vibration main frequency components. The feed pressure, tension pressure, cutter velocity, feed rate and tool arrangement during groove machining are optimized and precisely controlled to improve the accuracy of the pipe groove.
