What is High Fin Tube Rolling Machine?
The high fin tube rolling machine is used to roll single or dual metal finned tubed, which is used in industrial heat exchangers. It is also named tube finning machine, extruded fin tube machine and bi-metallic fin tube machine.
Aluminum muff tubes of different specifications are lined with copper tubes or steel tubes or carbon steel tubes (also known as base tubes), rolled and compounded by the 3 sets of cutter in the unit, and the fins are extruded at one time to achieve the effect of increasing the heat transfer area, the formed products is named high fin tube or extruded finned tube.
Structure
Tool holder and its body adopt the advanced dual-circular key structure to withstand torque and achieve accurate and reliable displacement.
Tool holder adopts split type design, make blade installation.
Spindle bearing can be moved using conical hydrodynamic sliding bearings to maximize the utilization.
Universal joins and shaft key link between all lines of hope pepper.
Cooling box is separated from rolling mill machine
Closely with technical data, rolling fin efficiently.
