The receiving member 18 is used by being disposed on the lower surface plate 62. The punching die 1 includes a three-dimensional strip-shaped blade 11, a base material 12, and an ultrasonic vibrator 13.

  FIG. 2 is a detailed explanatory view of the three-dimensional die 1. The band-shaped blade 11 has a three-dimensional loop contour (that is, a contour in which the contour of the blade tip T cannot be drawn on a plane), and a rectangular notch R and a bend notch B on the opposite side of the blade tip T. A plurality of (lower edges) are formed. The bend notch B may be left as a short straight line, that is, the end edge on the opposite side of the cutting edge T may not be processed, or the line contour on the opposite side of the cutting edge T is processed into a curved line. You can also.

  The base material 12 includes an upper base material 121, a lower base material 122, and a three-dimensional metal band 123. The upper base material 121 and the lower base material 122 can be made of a wood board (plywood, particle board), compressed paper, metal, or the like. Note that the upper and lower expressions of the upper base material, the lower base material, and the like are for convenience, and are expressions when the blade is facing upward, and are different from the vertical direction when installed on the surface plate.

  The upper base 121 has a uniform thickness, that is, the front and back surfaces are formed in the same three-dimensional shape. Further, the upper base 121 has a loop-shaped slit S formed so as to leave a region corresponding to the notch R. The loop contour of the slit S and the loop contour of the strip blade 11 are the same in plan view, and the strip blade 11 is inserted into the slit S so that the blade tip T protrudes from the surface of the upper base 121.

  The three-dimensional metal band 123 is made of stainless steel in the present embodiment, and is formed so that the three-dimensional shape follows the three-dimensional outline of the lower edge of the band-shaped blade 11. The lower base material 122 is formed so that the three-dimensional shape of the upper surface is the same as the three-dimensional shape of the lower surface of the upper base material 121, and the lower surface is formed in a planar shape. A shallow groove G having an outline of the belt-like blade 11 is formed in a portion of the lower base 122 corresponding to the lower edge of the belt-like blade 11.
