Rim Flash Butt Welding Machine

I. Technical process scheme:

1.Fit to the welding: let us discuss according to real products for the Automatic Butt Welding Machine.

2.Type: Horizontal structure, upper and lower jaw arms, 4 large parts are framed in cast steel structure, with PLC control, hydraulic clamping, touch screen, servo electric cylinder and linear rail guide to control the flash and upsetting. This fully configured design defines the performance of the Automatic Flash Butt Welding Machine.

3.Hydraulic clamping, servo electric cylinder flash and upsetting constitute the core drive system of the Flash Butt Welder.

4.Left and right clamping, the pressure is individually adjustable and displayed with a pressure gauge.

5.The movable board and the body are guided by linear rail.

6.The main transformer has a built-in temperature controller.

7.Two types of functions: pulsating and non-pulsating.

10. The hydraulic system includes a hydraulic valve block made by Rexroth (China).
11. The equipment is painted with titanium blue shrink varnish;
12. Linear rail guide     HIWIN         HGW55HA
13. Electrodes are made of chrome zirconium copper;
14. Accompanied with a set of hydraulic valve seals;
15. Accompanied with jaws: a set of chrome-plated copper electrodes are mounted on the body.

Following machine parameters as a example of UN-400KVA,

III. Requirement:
Purchaser should prepare by itself:
Power transformer: 1. Ordinary transformer >= 630KVA; only for this machine>=400KVA
Two-phase power source for main transformer A.B. 440V. >=180 mm2 copper wire    Distance <50 m.
Three-phase four-wire A.B.C.N 440V >=8 mm2 copper wire; (workshop power is enough)

Note: 1. The cracking rate due to welding is less than 0.5%, the rate of micro cracks is less than 10%.
2. In case of an equipment failure that cannot be solved by purchaser, supplier must give a response within 24 hours and seek a feasible solution. All costs and expenses incurred after the warranty period shall be separately discussed and settled by the parties.
