Then, air flows from the fluid supply path formed in the die holder 207 to the air outlet 213 through the circumferential groove 211.
- the diameter of the plurality of air outlets 21 is set to be smaller than the diameter of the fluid supply passage formed in the die holder 200. Therefore, the air flowing into the plurality of air outlets 21 from the fluid supply path formed in the die holder 207 is ejected from the air outlets 21 with an increased flow velocity. Thus, the downward suction action of the punched piece from the die hole 203 can be more effectively performed.
- FIG. 12 shows an aspect in which a part of the tenth embodiment according to the present invention is modified, and the air ejection port 3 13 of the die body 3 05 is formed thinner toward the tip, It has a nozzle shape. With this configuration, the flow rate of air is further improved at the tip of the air ejection port 3 13.
- FIG. 13 shows an aspect in which a part of the tenth embodiment according to the present invention is further modified, and the air ejection ports 4 13 of the die body 4 05 are connected to the tip side and the circumferential groove side.
- the air outlet is formed in two stages, an air outlet 413 having a relatively large diameter and an air outlet 415 having a relatively small diameter. Therefore, the two air drills 4 13 and 4 15 can be perforated by selectively using two types of drills having different diameters.
- FIG. 14 shows the die holder 7 of the die apparatus according to the first embodiment of the present invention from the bottom side.
- the fluid supply hole has two fluid supply holes 581, 581 formed on both sides of the fluid supply hole 35.
- the respective fluid supply holes 581 are formed with grooves 575 and 575 extending and bent to the positions of the respective dies.
- the grooves 575 and 575 are located on the upper surface of the die base 3.
- a pipe line is formed by making close contact with. Then, the air proceeds to the fluid supply paths 583, 583 formed in the die holder 7 via the pipe, and the air flows into the circumferential groove formed in the die. It is.
- the present invention is not limited to the above-described embodiment of the invention, and can be implemented in other modes by making appropriate changes.
