Pre Bending Machine For JCOE LSAW Pipe Mill Production Line


Overview of Pre Bending Machine For JCOE LSAW Pipe Mill Production Line

The Pre Bending Machine For JCOE LSAW Pipe Mill Production Line is the front-end forming device of JCOE LSAW pipe mill production lines, used for edge pre-bending treatment of steel plates before formal JCO molding. This Pre Bending Machine For JCOE LSAW Pipe Mill Production Line adopts a hydraulic multi-point pressing structure to bend the two edges of flat steel plates into a preset radian, solving straight edge residual problems after conventional integral bending. It matches the width and thickness parameters of raw steel plates to implement symmetrical edge forming on both sides. The Pre Bending Machine For JCOE LSAW Pipe Mill Production Line connects with production line conveying equipment to realize continuous feeding and pre-bending operation. Pre-set edge radian on this Pre Bending Machine For JCOE LSAW Pipe Mill Production Line eliminates pipe seam gap and edge misalignment during subsequent JCO forming. It standardizes plate edge forming dimensions and provides qualified raw workpiece conditions for follow-up molding, tack welding, and submerged arc welding processes.
