During the production and processing of the U-shaped cross beam, a mold needs to be used for press bending and forming operations.
[0003] At present, the existing U-shaped beam bending forming mold is usually designed and finalized with a single mold during design and development. In actual application, it is necessary to first perform loading and unloading operations, then perform bending and forming operations, and finally perform unloading operations.

By rotating and adjusting the rotating top seat, the bending lower die can be rotated to the bottom of the rotating top seat, and the U-shaped beam is bent by the bending lower die and the rotating top seat. After the U-shaped beam is bent, the rotating top seat is rotated again to switch the bending lower die at the bottom of the rotating top seat, so that the U-shaped beam inside the bending lower die can be loaded and unloaded by the robot.
[0010] Furthermore, a groove wheel is provided at the bottom of the rotating top seat, and the active dial is transmission-connected to the groove wheel, and the transmission ratio between the active dial and the groove wheel is 6:1.

[0014] In addition, the transmission motor drives the active dial to rotate through the synchronous belt. Every time the active dial rotates one circle, the active dial drives the rotating top seat to rotate one-sixth of a circle, thereby realizing the switching operation of the bending lower die at the bottom of the rotating top seat. When the rotating top seat stops rotating, the rotating top seat is limited by the active dial to ensure the stability of the U-shaped beam bending forming process at this time.
