First, in adding reference numerals to components of each drawing, the same components are described so as to have the same reference numerals as much as possible even if displayed on different drawings.

Figure 2 is a perspective view showing the form of a tool for thin plate hole processing according to an embodiment of the present invention.

As shown, the tool device for thin hole processing according to a preferred embodiment of the present invention is the top plate 100, the bottom plate 200, the top plate / bottom plate fixing means 300, the guide pin 400 and a plurality of holes It consists of a punch 500.

The upper plate 100 has a plate-shaped body, and the plate-shaped body has a fixing means insertion hole 120, a guide pin insertion hole 110 and a plurality of punching holes 130 through.

In addition, the lower plate 200 is also made of a plate-like body similar to the upper plate 100, the plate-shaped body has a fixing means insertion hole 120, guide pin insertion hole 110 and a plurality of punching holes of the upper plate 100. Fixing means insertion hole 220, guide pin insertion hole 210 and a plurality of punching holes 230 are formed in the same position so as to correspond to the 130.

Therefore, during the hole processing process, a thin thin plate 10 to be processed is inserted between the upper plate 100 and the lower plate 200, and each through hole 110, 120, formed in the upper plate 100 and the lower plate 200. 130, 210, 220, 230 should be exactly matched to each other, this function is performed by the upper / lower plate fixing means 300 and the guide pin 400.
