The cable tray machine is integrated with a pre-punching system to
make the wholes on the bottom and side of the tray. cable tray
forming machine is a big machine line. here comes the information
of the cable tray roll forming machine line:

Roll Forming Process
Description:
(1)Load coils onto the double head decoiler’s expansion system.
(2)Start the equipments and feed the material into the flattener
manually.
(3)The material after flattened is accurately fed into the
mechanical puncher for ordinal punching. The accumulated tolerance
of the central distance of holes is subject to the feeding system.
(4)The front and rear material stores are used to adjust the non
synchronization caused by the discontinuous moving in punching.
(5)The material after flattened and punched is rolled through the
specially designed tooling station by station to form the required
shape.
(6)At the end of the roll former a rectifying system is mounted to
rectify the shape and straightness of the formed product to the
final profile.
(7)The hydraulic cutter controlled by photoelectric switch and
measuring system is used to cut the finished material into required
length.
(8)The finished products, counted by the PLC automatically, are
conveyed to the simple run out table where the workers can take
them for package or to the warehouse.
Ⅱ. Main Configuration and Technical Details
The line is mainly consist of one double head decoiler, one
flattener, one front material store, one serve feeder, one
mechanical puncher, one roll former, one rectifying system, one
cutting system, one hydraulic system, one electrical controlling
system and one run out table, etc.
1. Double Head Decoiler
This decoiler with a steel welded structure, decoiling passively,
adopts coils with ID of 500mm. It is operated manually under which
it can load coils on both the heads which can be circumgyrated.
2. Flattener
According to the flatness accuracy requirement, the flattener,
calculating under the theory of minimum distortion is used to
flatten, convey and draught the material. The flattener has 5
flattening rollers, 2 feeding rollers and 2 delivering rollers. And
the distance of the rollers can be adjusted according to the
thickness and rigidness of the material to ensure an ideal
flattening function. The flattening rollers are made of heat
treated high alloy steel to ensure the rigidity and abrasion
proofed characteristics.
3. Front and Rear Material Stores
In order to match the speed of intermission feeding while punching
and the continuous feeding while roll forming for continuous
production, in front and rear of the puncher material stores are
supplied, in which the length of the material naturally sinks is
able to provide a cushion for the interval of punching and the
continuing of the roll forming. The dimension of the material
stores depends on the forming speed. Photoelectric sensor
equipment, mounted in the material stores, can stop or re start the
roll former when the accumulated material monitored is too long or
less.
4. Intermission Feeder
This system, adopting sever roller feeder and computer controlling
panel
