Steel pipe expanding machine manufacturer

Steel pipe expanding machine manufacturer

Expanding machine factory is a design and manufacturing experience for many years, where there are the wide order user can switch machine equipment, to provide customers the wide is expanding machine equipment quality assurance, cheap, expanding machine model according to the customer to provide manufacturing, manufacturing of expanding machine during the process of production technology of high precision, stable performance, convenient operation, high production efficiency, etc.

Pipe expanding machine is also known as expanding machine and expanding head machine, expanding machine and so on in pipe fitting equipment. Pipe expander generally adopts hot expansion steel pipe specifications in production; Diameter φ60 ~ φ1420mm, wall thickness 3 ~ 120mm, length 3 ~ 24m. Can be expanded to various materials of steel pipe (such as P91-92/T91-92, Q235, Q345, 45#, A106B-C, 12CrMoV).

The pipe expanding machine is designed for the lack of production and incomplete specifications of large diameter seamless pipe. The pipe fitting equipment is an oil cylinder or four oil cylinders parallel speed pushing machine. The valve platform of the pump station adopts the integrated form, according to the length of the outer diameter of the expanded steel pipe, the power of the intermediate frequency heating power source of the pipe fitting equipment, the thrust and stroke of the oil cylinder.

Tube expanding machine mainly includes: machine base, main cylinder support plate, movable push plate, front support plate, automatic feeding structure, feeding roller table, mold support, intermediate frequency coil adjustment frame, (including intermediate frequency heating coil) intermediate frequency power supply, electrical control system.

The operation process of the pipe expander: the washed pipe is sent to the rotating roller on the center line of the pipe expander. Using this rotating roller device, combined with a camera system, the pipe weld is rotated precisely to the 12 o 'clock position to ensure that the weld enters the groove in the upper sector of the expanding tool during subsequent reaming. The lifting cone roller lifts the pipe to the center line of the expanding machine, and the position is controlled by the displacement sensor in the lifting hydraulic cylinder. The clamping trolley moves forward and is controlled by the metal detector to detect the end of the pipe and gets stuck, and signals are sent to start the clamping trolley to feed the roller. The position is controlled by the encoder. In the process of moving, the metal detector at the expanding head is set to detect the front end of the pipe, so as to measure the position of the pipe. The tube length is combined with the expanding head to automatically calculate the number of expanding steps. The jaws of the clamp can be turned to avoid damaging the pipe wall. The height of the clamp can be adjusted to compensate for the straightenness deviation of the pipe and optimize the straightening effect of the diameter expander during running.
