Pneumatic re-flattening die of bending machine

The utility model discloses a pneumatic re-flattening die of a bending machine, which comprises a die body, the die body comprises an upper die and a lower die, the upper die is connected with the lower die, a re-flattening notch is formed between the upper die and the lower die, the top surface of the upper die is provided with a bending groove along the length direction, and the side surface of the lower die is provided with a guide strip. According to the pneumatic re-flattening die of the bending machine, through connection during separation, when one of the two dies is damaged, local replacement is convenient, overall replacement is avoided, the strength of overall equipment is improved through a fixing mode, and therefore the replacement cost of the equipment is reduced; the re-flattening die can be flexibly used according to different environments, and meanwhile, the die can achieve multiple operations such as re-flattening and bending through the operation of firstly bending and then re-flattening. 本实
