2. Structure character
PHJ15 H-beam Assembly-Welding-Straightening Integrating machine is
an advanced and high efficiency equipment for welding H-beam
production, integrating precision assembly, stable SAW welding,
flange deformation straightening and welding of H-beam together. It
has merits of compact structure, small area occupying, high
automatic and high productivity. It mainly consists of assembly
unitwelding unitstraightening unitconveyorhydraulic system and
electrical control system, etc.
2.1 Assembly unit:
There is 1 each centering positioning clamp unit of web and flange
set, adopts mechanical interlocked unit realizing synchronization
motion, one side is located by lead-screw while the other side
clamp by hydraulic pressure, lead-screw position is measured by
rotation encoder and digital display shows the data. The clamping
for wed and flange is powered by hydraulic cylinder, not only with
powerful strength, but also adding flexible of web and flange
clamping to accommodate flange width varies caused by cutting or
other reasons and web thickness varies due to web prolong welding
seam by means of automatic retraction to avoid work piece block.
There are 3 sets web and flange initial centering pulling rod at
the end of input conveyor, when hoist the flange and web to main
machine, it can make initial automatic centering for the central
line of machine and support the web, avoiding swing or overturn of
web and increasing the safety rate of operation.
The swing block rack at the end of H-beam assembly input can ensure
the end alignment of web and flange when assembling.
2.2 Welding unit
The main machine of Assembly-Welding-Straightening Integrating
Machine adopts flat welding to weld I-beam and H-beam, each one set
of SAW power at both sides. It adopts seam mechanical tracing,
tracing welding of both seams at both sides at same time.
Welding system collected by U.S.A LINCOLN DC-1000 power source and
NA-3S control box and wire feeder, which adopts twin arc welding
technology to achieve high welding efficiency and reliable quality.
There are 2 sets welding flux automatic feeding and recovering
unit, which can improve the welding automatization level.
Welding speed, that means work piece transportation speed adjusting
by variable frequency way, choose the reasonable weld speed
according to welding technology.
2.3 Straightening unit:
There will be distortion of H-beam flange for heat radiation,
continuous roller press straightening after seam cooling and
solidification. The straightening specification of work piece that
is straightening capacity refer to Fig1 and the table below ( work
piece material is Q235, tensile strengthσb=400Mpa, the other
material can adjust suitable according to material tensile
strength. For example, when tensile strength isσb=600MPa,
s=400/600=0.667, the flange width, flange thickness will be 0.667
times of figure in the following table):
The lower straightening roller drives work piece forward when the
upper roller straighten work piece by pressing downward. The
straighten capacity can be adjusted accordingly to flange thickness
and deformation condition to make continuous roller press
All straightening rollers are made by good quality alloy steel, and
finished by advanced heat-treating to avoiding the defect of
creating cranny easy, ensuring stability and long time using of
The straightening speed is same as assembly speed, which are driven
by the same motor reducer and controlled by variable frequency
The hydraulic elevation conveyor is set at the output side, which
can be elevated to certain height according to deformation of
welded H-beam and support the work piece to finish the whole
assembly, welding and straightening process.
Straightening speed and assembling speed is same, driven by same
motor and reducer, and adjusted by inverter. The speed of drive
motor is adjusted via Japanese MITSUBISHI A.C. inverter. Hydraulic
system equipped with fine filter is the standard product of
professional producer, which ensures the long and reliable
performance of solenoid valves.
