Abstract

The utility model discloses a die flexible supporting structure. The die flexible supporting structure comprises a plurality of nitrogen springs which are fixedly arranged on a lower die. The free height of a piston rod of each nitrogen spring coincides with the storage height of a die in a punching machine, the limiting height of each compressed nitrogen spring coincides with the working height of the die, and the bottom face, corresponding to the end portion of the piston rod of each nitrogen spring, of an upper die is provided with a buffering cushion. The nitrogen springs are arranged between the upper die and the lower die so as to replace an existing stationary-type supporting piece, when the dies are installed and changed, in the punching machine, the situation that two parameters needing to be adjusted is improved into the situation that parameters are adjusted in place once, therefore, waiting time for installing and changing the dies is greatly shortened, and installing space of the nitrogen springs is small and can be freely selected according to the requirements of different dies. Meanwhile, the damage, caused by the fact that staff forget to take down the stationary-type supporting piece, to the dies can also be eliminated.
