The bending process of automatic pipe bender can be completed fully automatic without the participation of personnel, but it still needs personnel to participate in the loading and unloading of pipe fittings. For fully automated production, the pipe bender can be equipped with an automatic loading device (Figure 1).

Figure 1 Automatic loading device

When used, the operator will put the pipe in the machine material preparation area, the material preparation area through the mechanical structure of the pipe will be transferred to the material rack, and then the loading machine will clamp the pipe on the material rack and put on the CNC pipe bender. The feeding car claw is hollow, so when the tube is in place, the feeding car moves to let the pipe through the pipe clamp, and when it reaches the appropriate position, the pipe clamp holds the pipe fitting and the feeding mechanism returns to its position. The pipe bender begins to bend. There are two loading positions at present.

One is in front of the feeding trolley (Figure 2)

Figure 2   Front-part loading

Although the feeding car can start to bend the pipe after clamping, but if the bending machine has auxiliary pull arm and multi-layer mold, the material on the loading machine needs to avoid many parts of the design is relatively complex.

And the other way is from the back of the car (Figure 3).

Figure 3  Back-part loading

The advantage of loading from the rear is less interference, The car and the loading device need to work together.

Since the matching gap between mandrel and pipe fittings is very small, if automatic loading is used, the mandrel cannot be used because of the error in movement.
