A lower mold stand 2 is fixed to the slide part 2 of the press (noted as "Press"), and a lower mold stand 4 is fixed to the press's bolster (not shown) via a punch 3 for height adjustment bit. There is C. A tie plate i-5 is fixed to the lower mold table 40, and a product Δ (a flat plate before being bent) is placed on this plate. A punch plate 6, a pan differential, and an E3 are fixed to the -F side of the upper die table 2. The punch plate 6 and the die plate 7.8 and the die plate 5 are hardened to form the J3.
In addition, the top end of the punch 7.8 is placed on the product Δ.
Punch out a predetermined part of the product △ through the n through hole 9 into Ritsubub 1 No. 1 (Figure 1 shows the state immediately after punching.) The upper side of the lower die table 4 and the upper 511 die 20 ) Guide bosses 1 to 10 and guide bush 11 are fixed to the upper side so that they are in a straight line, and the - It is arranged. These guide posts 10 and guide bushes 11 are provided to ensure that the positional relationship between the upper mold table 2 and the lower mold table 4 is accurately determined. A compression coil spring 12 is disposed between the stand 2 and the stripper plate 9 through a hole in the bump plate 6.

In the configuration of such a conventional apparatus, when drilling a predetermined part of the product A with a press, the integrated body of the upper mold table 2, punch 7.8, and punch plate 6 is 2. In this case, the stripper brake 1-0 is hung from a hanger bolt (not shown) as shown in FIG.

Then, in this state C Daishire 1-5 soil, Ijj product △
