OD.2500mmx40mm hydraulic machine for bending pipe

Specifications

A  The main function of the pipe bending machine

1   Pipe heat by the induction coil induction, can be bend by radius less than 6D and bigger than the 3D bend, maximum bending Angle is 180 °, the largest diameter 2500 mm, maximum thickness of 40 mm.

Material: low carbon steel, medium carbon steel pipe, alloy steel pipe, stainless steel pipe. Seamless, straight seam, and spiral pipe.

2   The front fixture open, lock, fixture head turning, radius adjustment are all hydraulic drove, through the button control.

3   The hydraulic system of the pipe bending machine drove by four different flow of oil pump, can be open according to need, ensure low-speed small flow drainage system, no fever.

4   Bending Angle sensed by the encoder, the terminal show on the liquid crystal display, Can dynamic feedback bending Angle, and the angle can be input preset via the LCD screen, Automatic stop after bending to scheduled Angle.

5   There are infrared thermometer for real-time monitoring of the heating tube, Keep pace with the speed to set Angle and automatically stop after that.

6   The output transformer is above the roller shelf, To facilitate the adjustment of the heating coil ( electric up and down adjustment, manual fine tuning left and right).

7   The whole machine focused on the control console (buttons and touch screen operation).

B The main technical parameters and features medium frequency power supply:

Power supply rated output power: 1500 KW;                                        

1   Medium frequency power supply from the main circuit to control circuit, is to use an adaptive digital control circuit, All control circuit for the three-phase bridge rectifier part, inverting part is parallel inverter, inverter Power rating from 5% - 100% range stepless adjustable.

2   Starting with reliable performance, No matter any artifacts in the inductor it can start reliably

3   Has a good stable performance. Current device used for the inner ring and intermediate frequency voltage for outer ring of the closed-loop system. When the input voltage fluctuations in the plus or minus 10%, stable output voltage accuracy + / - 1%, Thus ensure the consistency of the steel temperature inside the inductor during the heating process.

6   The inward lines without the phase sequence and no polarity outgoing requirements. Starting is zero voltage starting, no current shock.

C  Environment and working conditions

1  Environmental factors

Indoor temperature: top 40 ℃, 5 ℃ lowest; Air humidity: 98% or less (no frost);

2  Cooling water quality: life used tap water.

5  AC 380 v power connected to the distribution box for the pipe bending machne, total power is no less than 1500KVA.

6  hydraulic oil:45 # anti-wear hydraulic oil, Filter and aced on a regular basis.
