Online welded pipe thread rolling device

The on-line rolling device for welded pipe thread is set between the eight roll straightener of welded pipe production line and the fixed length flying saw, including the gear transmission box fixed on the base and the rolling cylinder installed above the gear transmission box. And a side bracket of the base, a support member arranged on the bracket, a guide frame, an inner groove guide plate, a connecting rod mechanism, a hollow shaft with a flange, a rotary table connecting member with a through hole and the rolling mechanism, which are characterized in that: a gear: the input shaft of the gearbox is connected with the belt pulley from the outside, and the output shaft is connected with the hollow shaft through the gear engagement part. One end of the connecting member of the turntable is fixedly connected with a flange on the hollow shaft through a bolt, and the other end has at least two "t" in the diameter direction. The chute is equipped with a T-shaped slider corresponding to the rolling mechanism, and a plug is arranged on the outside of the T-shaped chute.


The long arm of the guide frame is movably connected with the cylinder shaft joint at the axial end of the rolling cylinder, and the short arm is movably connected with the support on the bracket. The inner groove of the guide frame is provided with a groove shaped guide plate passing through the connecting shaft and groove. The groove guide plate is movably connected. The inner ring of the inner groove guide plate is fixedly connected with the rotary table connector through the flat key. At least two connecting rod mechanisms are arranged, the connecting rod mechanism comprises two hole connectors and three hole connectors. One end of the two hole connector is movably connected with the earphone arranged on one side of the inner groove guide plate, and the other end is hinged with one end of the three hole connector and the middle hole. The pin of the three hole connector passes through the pin and the pin seat of the rotary table connector. The pin hole is connected with the waist hole at the end, and can be movably connected to the pin hole arranged on the end slider of the rolling mechanism through the pin.
