Double-layer rear material blocking device of bending machine

The utility model discloses a double-layer rear material blocking device of a bending machine. The double-layer rear material blocking device comprises a rear material blocking structure. The clamping clip is used for connecting the rear material blocking structure with the blocking ruler; the rear material blocking structure makes contact with the rear portion and the bottom of the material piece at the same time so as to position the material piece. According to the rear material blocking device, on the premise that an existing blocking ruler of the bending machine is not changed, the problem of machining and positioning of small material pieces can be solved; based on the continuous characteristic of the double-layer rear material blocking device in the length direction, a plurality of materials can be placed at a time, and the working efficiency is greatly improved. According to the rear material blocking device, the transverse size of the device can be changed by adjusting the relative positioning of the
