On -line pipe cutting machine

The utility model discloses an on -line pipe cutting machine relates to pipe cutting technical field. On -line pipe cutting machine includes workstation, tracking means and cutting device. The workstation sets up on the follower along first with predetermineeing the direction slidable. The workstation sets up in screw actuation mechanism, and reciprocating motion is made along the first directionof predetermineeing to screw actuation mechanism drive workstation. Cutting device includes cutting mechanism, pipe clamping mechanism and surely manages feed mechanism. Surely manage feed mechanism and include the cutting bed, feed platform and crank rod drive portion, cut the establishment of institution on the cutting bed. Crank rod drive portion is connected with the cutting bed transmission,thereby crank rod drive portion is constructed as that it makes reciprocating motion and be close to pipe clamping mechanism or keep away from pipe clamping mechanism to make the cutting bed predetermine the direction along th
