Electrical Control System Pipe Expanding Machine For Producing 426mm Diameter Tubes

Used for produce diameter of 426mm carbon steel and alloy steel pipe hot induction tube expander

The main components of the tube expanding machine include: stand, main oil cylinder support plate, movable push plate, front support plate, automatic feeding mechanism, discharging roller table, mold support, intermediate frequency coil adjusting frame, (including intermediate frequency heating coil) intermediate frequency power supply, electrical control system.

Operating process of the expanding machine: the rinsed pipe is sent to the rotary idler device on the center line of the expanding machine.Using this rotating idler device, combined with the camera system, the tube weld is precisely rotated to the 12 o 'clock position to ensure that the weld can enter the groove of the upper sector of the tool during subsequent diameter enlargement.The lifting cone roller way lifts the pipe to the center line of the reaming machine and the position is controlled by the displacement sensor in the lifting hydraulic cylinder.The clamping trolley moves forward and is controlled by a metal detector to detect the end of the tube and to secure it. At the same time, a signal is sent to start the feeding roller of the clamping trolley. The position is controlled by an encoder.The pipe length is combined with the reaming head to automatically calculate the optimal reaming steps.The clamp jaws can be rotated to avoid damaging the tube wall.During the advance, the height of the clamp can be adjusted to compensate for the pipe straightening deviation and optimize the straightening effect of the reamer.

The equipment mainly includes: machine base, main oil cylinder support plate (including main oil cylinder), movable push plate, front support plate, automatic feeding mechanism, blanking roller table, mold support, intermediate frequency coil adjustment frame (including intermediate frequency heating coil), intermediate frequency power supply, electrical control system and so on.

Specification of hot expanding steel pipe: diameter 89 ~ 1420mm, wall thickness 30 ~ 150mm, length 3 ~ 24m.Steel tubes of various materials can be expanded (such as p91-92 / t91-92, Q235, Q345, 45#, a106b-c, 12CrMoV).

Special equipment for steel tube hot hole enlargement, mainly for domestic large diameter steel pipe production cannot meet the demand of market and all kinds of steel pipe specification is not complete, meet the needs of small batch more varieties of steel pipe production, can satisfy the different material steel pipe hole enlargement and various non-standard steel tube expanding needs, is currently the main production process of large diameter steel pipe.It has been widely used in military industry, power plant construction, aerospace industry and Marine industry equipment manufacturing industry, making a great contribution to the steel pipe industry and energy construction.
