Abstract

Provided is a blanking die which causes no slack of a fixed punch and carries out exact blanking even if a large number of sheetlike materials are blanked at a high speed, and also to provide a blanking die which easily separates products obtained by blanking the sheetlike materials from the scraps, and causes no pollution problems even if the disposal by incineration is carried out. Base materials 2, 3 of the blanking die have spaces 4 surrounding the punch 1. Resin is charged into the spaces and is solidified to fix the punch 1. Further, the spaces 4 are filled with gas, and the base material 2 is provided with a plurality of gas flowing-out holes. As a result, the products and the scraps are easily separated by flowing-out the gas through the gas flowing-out holes.

Description

technical field [0001] The present invention relates to a punching die for punching a sheet-like material such as a plastic plate or a corrugated cardboard into a desired shape and a method for manufacturing the punching die. technical background [0002] A conventional punching die will be described with reference to the drawings. [0003] Figure 19 To show a perspective view of a conventional punching die, Fig. 20(a) is the edge of a thin groove formed using a laser beam. Figure 19 Y, the enlarged cross-sectional view of the Y line, Figure 20(b) is the edge when using end mills and steel wires to form fine grooves Figure 19 Y, Y-line zoomed-in profile. Conventionally, as a punching die for punching a sheet-like material such as a plastic plate or a corrugated cardboard into a desired shape, a plate-shaped body (referred to as a "base material" in this specification) made of wood such as a veneer, for example, has been used. A base material 2 composed of a plywood, a pl...
