The technical scheme is adopted: through setting up bearing and installation pole, can effectively install the live-action roller.

The utility model is further arranged that the inside of the bottom plate is sleeved with the mounting bolt, and a round hole matched with the mounting bolt is formed in the inside of the bottom plate.

The technical scheme is adopted: through setting up the mounting bolt, can effectively install the device.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, a machined part is placed at the top of the lower die, then the bending machine is started to drive the upper die to bend the machined part, and then the machined part drives the rotating roller to rotate when entering the lower die, so that the rotating roller bends the machined part by a negative angle through the groove, and the negative angle can be effectively bent to the machined part;

when the upper die is reset, the upper die brings out the machined part, and the spring drives the rotating roller to rotate and reset, so that the rotating roller can be effectively and rapidly reset.
