MAX.OD.820-2500mm carbon alloy stainless steel pipe bending hydraulic machine

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.

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;

Rated output frequency: 500-1000 HZ;

The rated output voltage: 750 V;

The rated input voltage: 380 V - 450 V;

The rated dc current: 3000 A.

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.

4 Has overcurrent, overvoltage, water pressure, the fuse are short etc,multiple protection, Effectively protect the safety of power electronic devices.

5 All integrated device mounted on a panel.

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°C, 5°Clowest; Air humidity: 98% or less (no frost);

4 Cooling water circulates, The buyer is responsible for the configuration of cooling water system. Water pressure shall be 0.25 Mpa or higher.

5 AC380 v power connected to the distribution box for the pipe bending machne, total power is no less than 1500KVA.

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

D Pipe bending machine configuration instructions

1 Main oil cylinder:inner diameter: 400 mm,outer diameter: 480 mm trip: 12 m maximum thrust: 530 tons

2 Hydraulic pump station:

Pump selection: 40scy plunger pump 1 set ,1kw motor 1 (the main pump frequency control of motor speed)

……………………

40scy plunger pump 1 set,11kw motor 1 set (guide wheel, motor with fixture).

Hydraulic motor 7 sets.

1 set of hydraulic control valves (Rexroth models)

3 Assembly:

Fixture, clamping wheel adopt 45 # steel casting

The main framework,molding plate weldments, push master board are plate weldments

Screw, chains, standard parts, bearings are of national standard

Guide for board form dovetail groove

5 Uses the Omron encoder to measure oil cylinder speed, In a real-time display,Can also be used for setting the stop when get to a certain distance and set in place after the stop. The angle encoder calculates the bending angle and show on the screen, the bending angles should be preset.

6 Intermediate frequency sensors can be combined with programming system, Through the thermometer and the speed encoder adjust the bent pipe temperature, speed, hydraulic valve to the set temperature, after that the oil cylinder driving steel pipe bending forward, speed mate to the temperature, when bend to the set angle, the intermediate frequency and the master machine stop. Touch screen is Taiwan Weilun 7 inch colorful LCD, Siemens series is used in the programming system
