Water circulation device for cooling and shaping in pipe production

The utility model discloses a water circulation device for cooling and shaping in pipe production, which relates to the technical field of pipe production and comprises a frame, a cooling cylinder, a cooling cavity, a first cooling chamber and a second cooling chamber, and the cooling cylinder is fixedly mounted on the frame. During use, firstly, one end of a pipe is placed in the cooling cylinder, then the driving motor is started, the driving motor drives one rotating shaft to rotate, then the other three rotating shafts are driven to rotate synchronously under the action of the first transmission assembly, and when the four rotating shafts rotate, a plurality of screw rod guide sleeves rotate synchronously through a plurality of second transmission units; and a screw rod and a plurality of U-shaped mounting plates are driven to synchronously move in the axis direction under the action of a plurality of limiting units, so that a plurality of clamping rollers are driven to clamp and limit a pipe, and therefo
