The working principle of hydraulic two-step pipe expanding machine
The material on the two-step hydraulic pipe expanding machine is driven by the feeding coiling machine, which drives the steel wire rope, pushes the pipe, and reciprocates through the steel wire rope wheel. The raw pipe to be expanded is sent to the pipe expanding machine.
Medium frequency power supply installed in the device's front end, medium frequency induction coil placed on the shelf, good expansion tube core head mould and expanding the original pipe, a open water pump and intermediate frequency power supply, adjustment of intermediate frequency power, can for expanding core mold and heating pipes, again to start the expanding machine, tube expanding.
The controllable silicon of the medium frequency power supply, the medium frequency coil, the compensation resonant capacitor, the reactor and other components need circulating water cooling.
The electrical control part of the pipe expanding machine is installed in the general control cabinet. The stroke switch is installed at both ends of the pipe expanding machine. After the push plate is in place, the machine will stop automatically. |
