[0006] A fixing block is fixed on the top of the base, and a fixing plate is fixed on the fixing block via a second screw, and a second stamping part that matches the first stamping part is fixed on the fixing plate.

[0007] Preferably, a hydraulic rod is fixed to one side of the connecting frame, and a limiting member is fixed to the output end of the hydraulic rod.

[0008] Preferably, a groove is provided on the connecting frame.

[0009] Preferably, the fixing plate is provided with an opening adapted to fit the second screw.

[0010] Preferably, the second stamping part is provided with a stamping groove adapted to the first stamping part.

[0011] Preferably, the bolt is provided with a nut adapted to the bolt.

[0012] Compared with the related art, the stamping and bending die provided by the present invention has the following beneficial effects:

[0013] The utility model provides a stamping and bending die. By replacing a suitable first stamping part and a second stamping part, a plate is placed on the second stamping part, and a hydraulic cylinder is started to drive the first stamping part to stamp the plate. The first stamping part cooperates with the second stamping part to stamp and bend the plate. The utility model solves the problem that the existing plate stamping and bending die has a single function, poor stability, and is difficult to replace stamping dies of different specifications, which greatly affects the processing efficiency of the plate.
