Automatic Radiator Fin Machine 0.6Mpa Pneumatic System Working Pressure

Automatic Radiator Fin Machine 0.6Mpa Pneumatic System Working Pressure

1. Summary

The radiator fin machine is used to produce heat exchange wavy fins with or without windows.

The fin radiator making machine is equipped with the following devices: decoiler, tensioning device, feeding,

interval oil lubrication, fin forming, correction and cutting function, strip run-out detection, blockage detection device,

cutting fault indicator, fin forming unit overloading protection device, and fault indication light.

The CPJ type radiator fin machine adopts PLC, inverter, AC servo control, and touch screen control.

The parameters are easily set through the touch screen. 

2. Main Technical Parameters

3. Fin Forming Unit Technical Parameters

4. Composition

4.1   magnetic powder brake: equipped on the decoiler frame. The decoiling speed is controlled by

the resistance force of the magnetic powder brake.

4.2  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.  

4.3 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.  

4.4  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 strip runs out.  

4.5  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 strip must be covered with an oil film to protect the

fin forming unit. And also the impurities could be wiped out.  

4.6 fin forming unit: it is the most important part of the fin making machine. It is driven by the inverter motor.

4.7 separation device: one upper and one lower separation sheets which can separate the formed strip

from the fin forming unit to avoid blockage.

4.8 fin convolution wheel: a pair of fin convolution wheel to bend the formed Aluminum strip, keep the

convolutions and conveys them to the next unit.

4.9 collection device: the spring damper pops out the closely packed Aluminum strip to get the basically formed fin.    

4.10 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. There is a 2-grade fin pitch device to adjust the fin pitch.                                            4.11 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.

4.12 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.  

4.13  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.  

4.14 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.

4.15 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.   

4.16 The working table of the fin forming unit is made of Aluminum alloy material.

And the fin forming unit is made of an organic glass cover.

5. Configuration of fin radiator making machine 

Note: The customer should provide the aluminum coil size so that the seller could design the decoiler.

(usually coil size: ID 70-Φ210 mm; OD: Φ1500 mm)  

6. Acceptance

The buyer is to prepare a minimum of 20kg Aluminum strip for testing the equipment. And the equipment is

ready for delivery after acceptance by the buyer’s representative at the seller’s factory.

7. Installation

When the equipment arrives at the buyer’s site, the buyer should be responsible for erecting the

equipment at the right place according to the seller’s instruction. The seller should provide assistance to the former.

The installation of the equipment is done by the seller while the buyer should provide assistance to the former.
