Equipment composition of the expanding machine: The mechanical expanding machine is composed of a rotary support roller device, a lifting cone roller track, a driving pull rod sleeve support roller, a length measuring roller, a clamping car, an expanding head, a pull rod, a pull rod sleeve, a hydraulic cylinder, and an expanding machine frame. The function of a mechanical expansion pipe machine is to gradually expand and connect large-diameter straight seam submerged arc welded pipes with an expansion head, in order to obtain the roundness, straightness, and dimensional accuracy required by the standard process.
Process: The washed pipeline is sent to the rotating roller device on the centerline of the expanding machine. Using a rotating roller device and camera system, accurately rotate the pipeline weld seam to the 12 o'clock position, ensuring that the weld seam can enter the groove of the sector on the expanding tool during the subsequent expansion process.
The lifting cone roller conveyor lifts the pipeline to the centerline, and the position is controlled by the displacement sensor in the lifting hydraulic cylinder. The clamp car moves forward and is controlled by a metal detector to detect the end of the pipe and clamp it. Simultaneously send a signal to start the feeding roller of the clamp truck, and the position is controlled by the encoder. During the movement, the metal detector at the expansion head detects the front end of the pipe, thereby measuring the position of the pipe. Combine the pipe length with the expansion joint to automatically calculate the number of expansion steps. The jaws of the pipe clamp can rotate to avoid damaging the pipe wall. During the promotion process, the height of the pipe clamp can be adjusted to compensate for the straightness deviation of the pipeline and optimize the straightening effect of the expansion machine.
The above is some knowledge about expanding machines that Huajin Heavy Equipment has compiled for you, hoping to be helpful.
