In this way, by arranging a plurality of bending components on the base, the copper tubes can be bent at the same time, thereby improving efficiency.

When bending the copper tube, the copper tube passes between the fixed die and the movable die, and reaches between the bending wheel, the bending die and the supporting die. The lifting structure drives the supporting die to rise, and clamps the copper tube through the supporting die and the bending die. The lifting assembly drives the movable die to rise into place, and the power input structure drives the turntable to rotate, thereby driving the bending wheel and the bending die to rotate, and the supporting die rotates accordingly, so that the copper tube is bent around the bending circular groove of the bending wheel.
