Large Dia Carbon Steel Pipe Expander Machine , Automatic Pipe Expander 850T

Used for manufacturing of large diameter carbon steel pipe expanding machine

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.
 

Compared with manual heating of steel pipe, the intermediate frequency tube expander simplifies the process and reduces labor cost and time.Increased production efficiency.
The equipment consists of the main engine of the hydraulic pusher, the automatic feeding and discharging mechanism, the hydraulic pump station, the tube adjusting device, the operating platform, the motor control cabinet, the intermediate frequency power supply, the compensation capacitor, the water cable, the intermediate frequency coil adjusting frame, the reactor and other components.Medium frequency tube expanding machine has an advantage is the intelligent constant temperature system, can effectively avoid due to human factors caused by the temperature is too high to pull down the quality of the steel tube and die scrap, or the temperature is too low to cause the rod and die fracture phenomenon, put an end to the unsafe factors.
