The mold wheel 21, the fixed small roller 4 and the bending small roller 6 with proper sizes are selected according to the size specification of the refrigerant pipe workpiece 3, and the refrigerant pipe bending device is assembled.
The refrigerant pipe movable clamp of the refrigerant pipe bending device is positioned in the state of fig. 1, and the fixed end of the refrigerant pipe workpiece 3 is inserted between the die wheel 21 and the bending small roller 6 until the fixed end of the refrigerant pipe workpiece 3 can be fixed by the fixed small roller 4.
