An electroforge
(EFG)-welding machine is a dedicated machine used to make steel bar
grating from flat steel (bearing bar) and twisted bar (cross bar).
It is a key machine in whole steel bar grating production
line.
The steel bar
gratings manufactured with this equipment meet requirements of such
a Standard as YB/T******8 (Chinese Metallurgical Standard),
ANSI/NAAMM (MBG *****8) (USA) and BS ********7
(UK).
The EFG - welding
machine is classified as single bar type and double- bar type on
welding function. Single bar EFG-welding machine means one cross
bar is welded at a time, for example type GYH*****1A, being
suitable for small scale production. Double bar one means two cross
bars are welded at a time. The most of products we provided are
double bar type ones.
The EFG - welding machine is also classified as
A.C. type and D.C. type on welding power supply. D.C. type means
that D.C. power work as welding power supply. It is realized to
change A.C. power into D.C. power by means of a rectifier. The
welding power of A.C. EFG-welding machine can be supplied in
different three methods as below: single phase power supply,
*-phase power supply with phase controller, and reverse power
supply.
A.C. reverse type
is the latest design based on reverse technique. Welding power is
from A.C. 3 - phase power supply and then reverse changes to
A.C. single phase power supply output through a reverse –
controller, and finally goes through a single phase step-down
transformer for welding current output. In this way the
problem of single power supply for A.C. EFG -welding machine is
solved, preventing a power grid from unbalance. Its outstanding
advantage is high efficiency and energy preservation. The
efficiency can reach up *0% *- *0%, preserving energy 1/3 more than
traditional EFG -welding machines. Utilization of reverse technique
in welding main circuit design results in efficient increase in
power factor of the welding equipment. The power factor for
electric power supply can be over 0.9 even without a power factor
compensation device. In addition, the reverse circuit is controlled
with an embedded computer CPU being simple in structure, reliable
in operation, and excellent in anti-interference. Modularized
structures are utilized in the whole reverse power supply. Each
modular unit generates power output **5KVA. Different numbers of
modular units can be assembled to form such sizes of products as
**0, **0 and ***0 EFG-welding machines.
The welding main
machine, briefly to say, consists of a set of hydraulic press plus
such a unit as welding power supply set, conductor row, electrode,
electrode seating, combing clamp (bearing bar positioning device),
pressing rollers, welding deformation correcting blocks and cooling
pipes, etc.
There are following
common features for all types of EFG-welding
machines:
1)
Cross bars (twisted bars) are manually laid and automatically
fed.
2)
Bearing bars are manually positioned and automatically
fed.
3)
Steel grating is auto-repeatedly clamped & sent out by dragging
device.
4)
Switchgear cabinets are equipped with a primary current indicator
and a voltmeter.
5)
Longitudinal welding distortion is automatically
corrected.
6)
Both manual mode and automatic mode can be selected in operating
console. The operating console is fixed with man-machine interface
touching screen and LCD.
7)
Welding parameters are set and stored sections in PLC (data never
disappear even if power supply is interrupted). Parameters are set
with intelligence and indicated with digital
display.
8)
Linear ball rail is used in steel grating dragging
device
Technical
parameters depend upon type of EFG –welding machine. Please see
Selling Offer for details.
