Further, the upper surface of described die 2 is provided with the pin for locating.

Further, on described die shoe 1, offer bar-shaped trough, after limiting plate 20 and described bar-shaped trough, described limiting plate is fixed on described die shoe described in screw bolt passes.

Further, the upper surface of described die 2 offers die cavity, and the sidewall of described die 2 is run through in the left side of described die cavity.

Further, the bottom surface of described die cavity is arcwall face.

(3) beneficial effect

The utility model thin-wall part knife edge die, simple in structure, substitute the laser cutting machine in traditional handicraft, milling machine and abrasive wheel cutting machine by common punch press, greatly reduce production cost, simplify production process, improve production efficiency; Avoid multiple bearing to cause deviation accumulation, improved making precision; Also corresponding raising of production stability, has avoided the generation of product rejection phenomenon simultaneously.
