radiatorhaveMultiple heat dissipation systemspipe、Base, heat dissipation fin components, bracketcomposeDue toheat pipeThickness is relatively highsmall，There are many heat dissipation fins, making the connection difficult,Need to eliminateheat pipeThe gap between the heat dissipation fins (05mm-0.8mm）Achieve interference fit to prevent looseningThis is the function of the tube expander.

IIIComposition of tube expanding machine

pneumaticwater pressureThe tube expander consists of three parts: the electronic control part, the pneumatic boosting system, and the expander. The electrical control adopts Siemens PLC control. The pneumatic boosting system adopts two Saist high-pressure expansion tube machines and liquid superchargers Can quickly increase pressure, pipe diameterThe boosting time within 15mm in length and 5m reaches the predetermined pressure within a few tens of seconds.

4Main technical parameters

1. Rated expansion pressure: 0-100MPa

2. Expansion speed: about1-2root/Min (water injection - expansion joint, slightly different depending on the length and diameter of the pipe fittings, etc.)）

3. Expansion medium: water

4. Input power supply: 220V

5. Drive: Compressed air5-8 kilograms

6. Water source: tap water

7. Control system: PLC

8. Voltage control accuracy:+-1%

9. Workstation: 1 workstation

5Product Features

1. The expansion fixture is easy to operate, convenient to clamp, and has a high clamping force,

2. canon one's ownSet the holding time and expansion pressure to ensure the quality of the expansion joint;

3. Foot switch control is convenient to operate

4. The speed of pressure rise and release is fast, and the expansion speed is doubled;yesmechanicalSwollen joint3timesabove.

5. Perform a one-time uniform expansion joint on the entire thickness of the heat dissipation tubes and fins;

6. The residual stress of the device after expansion is low, making it less prone to gap corrosion;

7. After expansion, the axial direction does not elongate but slightly contracts, which is beneficial for reducing operating noise;

8. There is no pollution at the expansion joint, and the expansion before welding is not affected;
