Fully automatic Copper Radiator Fin Machine 100 M/Min Wavy Fin
Summary of Fin Machine
The machine is used to produce heat exchange wavy fins with or
without windows.
The machine is equipped with the following devices: decoiler,
tensioning device, feeding, interval oil lubrication, fin forming,
correction and cuttig function, strip run-out detection, blockage
detection device, cutting fault indicator, fin forming unit
overloading protection device, and fault indication light.
The copper fin making machine adopts PLC, inverter, AC servo
control, and touch screen control. The parameters are easily set
through the touch screen.
Fin Forming Unit Technical Parameters
The fin forming roller is the most important parts of the fin
machine.
It can be customized based on the customer's fin drawing.
The fin forming roller is completely processed by our factory, and
it makes the total cost of the radiator fin machine highly
competivie in the market.

Composition of Equipment
1 magnetic powder brake: equipped on the decoiler frame. The
decoiling speed is controlled by the resistance force of the
magnetic powder brake.
2 decoiler: The coil tray supports the coil and it can tighten or
loosen the tray by adjusting the tray claw. The changing resistance
value of the potentiometer automatically controls the resistance
force of the magnetic powder brake. When there is an emergency, the
decoiler can be stopped immediately.
3 feeding resistance adjustment structure: the fin making machine
is set with an automatic feeding system. The damper controller
controls the resistance force of the magnetic powder brake to keep
the coil feeding speed matching the feeding speed of the fin
forming unit.
4 feeding tensile force adjustment mechanism: consisting of strip
run-out detection mechanism, bracket, and pneumatic cylinder. The
fin height can be micro-adjusted by changing the working pressure
of the cylinder. The strip run-out detection mechanism could cut
the power supply of the whole machine when the Aluminum/Copper
strip runs out.
5 fin lubrication device: consisting of upper and lower oil chamber
and oil immersing felt. Before entering the fin forming unit, the
two sides of the Aluminum/Copper strip must be covered with an oil
film to protect the fin forming unit. And also the impurities could
be wiped out.
6 fin forming unit: it is the most important part of the fin making
machine. It is driven by the inverter motor.
7 separation device: one upper and one lower separation sheets
which can separate the formed strip from the fin forming unit to
avoid blockage.
8 fin convolution wheel: a pair of fin convolution wheel to bend
the formed Aluminum/Copper strip, keep the convolutions and conveys
them to the next unit.
9 collection device: the spring damper pops out the closely packed
Aluminum/Copper strip to get the basically formed fin.
10 fin pitch correction device: the basically formed fin can’t meet
the fin pitch requirement, and the fin pitch should be achieved by
the fin pitch correction device.
11 fin conveyance device: the device is controlled by a stepping
motor and a worm rod to convey the finished fin and count the fin
convolutions at the same time. When the fin convolutions has met
the set value (i.e., the fin length), the stepping motor stops and
PLC controls the cutter to cut off the fin. The fin is cut at the
fin crest.
12 worm rod: the choice of the worm rod is decided by the pitch of
the fin. Different fin pitch should work with different worm rod.
13 blockage detection device: consisting of motor, detection probe
and isolation block. The electrode works with DC 24V voltage. This
blockage device is installed at the exit side of the fin forming
unit. When the electrode probe detects a blockage, the control loop
power is cut off, and the motor is stopped immediately to protect
the fin forming unit.
14 cutter: consisting of cutter stand and dual-direction adjustable
buffer pneumatic cylinder. There is a 2-position 5-direction valve
to control ON/OFF of the cutting cylinder.
15 oil spray mechanism: consisting of solenoid valve, vacuum
generator, and pipes. The vacuum generator draws the volatile oil
of the oil tank by ON/OFF of the solenoid valve and then spray the
oil mist on the blade rollers for lubrication.
16 The working table of the fin forming unit is made of
Aluminum/Copper material. And the fin forming unit is made of an
organic glass cover.
