Componets Descriptions of Galvanized Steel Guardrail Production
The maximum capacity of the coil decoiler can hold is 5 tons. It is
designed for the coils with 508mm
inner-diameter and maximum 1000mm outer-diameter.
It adopts wheel and screw which are used to regulate the iron stick
for direction guilding.
This leveling device adopts 7 rollers (3 rollers up and 4 rollers
down) to make the steel sheet flatly into
the rolling system.
The main frame of machine is welded separately and the outside wall
is connected by screws after being painted on the surface. The
rollers are made by Cr12 mould steel of high quality, which are
processed with quenching treatment. The rolling shafts are made by
No.45 carbon wrought steel of high quality, which can improve the
integrated mechanic feature of the rolling shafts, then the rolling
shafts will be processed by cylindrical grinding machine to ensure
the precision of final products.
Holes Punching Device:
The holes punching dies are made by Cr12 mould steel to get a good
hardness and lifespan.
Cutter blade is made by Cr12 mould steel with heating treatment.
The cutter’s structure adopts welded frame for good rigidity. The
power of cutting action is provided by hydraulic station.
Supporting Tables for Finished Products:
They are used to support the finished products. It is convenient
for the workers to stack the finished products.
Hydraulic Station for Cutting Device:
The motor and hydraulic accessories are with famous Chinese brand
which guarantee the hydraulic station is supplying stable the power
for the step presser and cutter.
PLC Control Cabinet:
The control system adopts Mitsubishi PLC, inverter, touching screen
for all the working actions of the machine. Some parameters, such
as product quantity, product length and so on can be set into the
PLC controller, then this machine will automatically produce the
desired products according to the set parameters.
Tools Box with Spare Parts:
The tools box contains the necessary tools such as spanners,
screwdrivers, pilers, oil pot and useful spare parts such as
control buttons, position switches, mini relays, chains and so on.
The finished guard rail sheets are widely used in the crash
barriers of highway.
