Abstract
The utility model discloses a seamless pipe perforating machine top head cooling device. The seamless pipe perforating machine top head cooling device comprises a perforating cart body, a hollow rotating main shaft and a cooling water pipe. The rotating main shaft is rotably arranged in the perforating cart body through a bearing. A connecting frame is installed on the tail portion of the perforating cart body. A sealing cover is installed on the end portion of the connecting frame and provided with a through hole. The cooling water pipe penetrates through the through hole and penetrates into the rotating main shaft to arrive at a top head. One end, stretching out of the connecting frame, of the cooling water pipe is connected with a water inlet pipe through a rotating connector. In the rolling process, because the rotating connector is additionally arranged on the seamless pipe perforating machine top head cooling device, the top head rotates to drive the cooling water pipe to rotate together with the rotating main shaft, the cooling water pipe is prevented from cracking, pressure of water flow can be kept, and the temperature of the top head is reduced. The seamless pipe perforating machine top head cooling device reduces maintenance cost and fault time and improves working efficiency and productivity.
