By opening multiple sets of annular slots with different diameter specifications, it is possible to easily adapt and process metal pipes of different diameters. Then, the servo motor is rotated with a preset frequency to intermittently control the drive shaft to drive the rotating tray and multiple sets of lower insertion molds to rotate. At the same time, the necking hydraulic cylinder is installed with a preset frequency to control the extension and retraction of the hydraulic telescopic rod. The operator continues to insert metal pipes into multiple sets of adjacent lower insertion molds. When the lower insertion mold with the inserted metal pipe rotates to below the upper necking mold, the hydraulic telescopic rod extends downward to push the upper necking mold towards the metal pipe for necking. After the metal pipe is necked, it is rotated to the operator, pulled out, and then inserted into the metal pipe to be processed. In this way, the necking process of metal pipes can be achieved efficiently. Attached Figure Description
