In order to achieve the above purpose, the invention provides the following technical scheme: a combined cutting die comprises a cutting die holder and a blade, wherein the blade is movably arranged at one side end of the cutting die holder in the thickness direction, a locking block is arranged on the outer side of the blade, and a punch pressing plate and a punch are arranged at one side of the cutting die holder in the thickness direction.

As an improvement of the invention, the knife die holder is disc-shaped, the blade is annular, the locking blocks are annular blocks, the locking blocks comprise a first arc-shaped locking block and a second arc-shaped locking block, and the middle parts of the first arc-shaped locking block and the second arc-shaped locking block in the arc length direction are connected with the knife die holder through first fastening screws.

As an improvement of the invention, the first arc-shaped locking block and the second arc-shaped locking block are both in a semi-arc shape, both ends of the first arc-shaped locking block in the arc length direction are respectively provided with a first connecting screw hole, both ends of the second arc-shaped locking block in the arc length direction are respectively provided with a second connecting screw hole, and connecting screws are respectively screwed into the first connecting screw holes. The connecting screw can penetrate through the first connecting screw hole and be screwed into the second connecting screw hole.

As an improvement of the invention, the punch press plate and the blade are all arranged on one side of the knife die holder in the thickness direction, the punch press plate and the punch are all arranged on the inner side of the blade, one end part of each punch in the length direction movably penetrates through the punch press plate, and second fastening screws are uniformly arranged between the punch press plate and the knife die holder. A gap is reserved between the outer side end wall of the punch pressing plate and the inner side end wall of the blade.

Compared with the prior art, the invention has the following advantages: this combination cutting die can realize the detachable of cutting die holder and blade through the latch segment and be connected, and the blade can be realized changing alone, and cutting die holder repeatedly usable, resources are saved, reduce cost. The punch is pressed on the cutter die holder through the punch pressing plate, so that the punch is convenient to detach and replace.
