Overview
Inflatable water pressure tube expanding machine (tube+fin expansion, pipe fittings overall inflation type) 1. Application scenarios: Stainless steel tubes, aluminum tubes, copper tubes, steel tubes, etc. are expanded with fins. Cooling equipment such as radiators, condensers, and surface coolers are expanded with fins. Quick freezing equipment is expanded with tubes and fins. 2. The radiator is composed of multiple heat dissipation tubes, bases, heat dissipation fin components, and brackets. Due to the small thickness of the heat dissipation tubes and the large number of heat dissipation fins, the connection is more complicated. It is necessary to eliminate the gap (0.5mm-0.8mm) between the heat dissipation tubes and fins to achieve interference fit and prevent loosening

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

5Product Features
①The expansion fixture is easy to operate, convenient to clamp, and has a high clamping force,
②canon one's ownSet the holding time and expansion pressure to ensure the quality of the expansion joint;
③Foot switch control is convenient to operate
④The speed of pressure rise and release is fast, and the expansion speed is doubled;yesmechanicalSwollen joint3timesabove.
⑤Perform a one-time uniform expansion joint on the entire thickness of the heat dissipation tubes and fins;
⑥The residual stress of the device after expansion is low, making it less prone to gap corrosion;
⑦After expansion, the axial direction does not elongate but slightly contracts, which is beneficial for reducing operating noise;
⑧There is no pollution at the expansion joint, and the expansion before welding is not affected;
