And the drilling disk-shaped members 8, 8,. 6, the shaping disk-shaped members 14, 14,... And the drilling disk-shaped members 15, 15,.

When a flat metal plate is inserted from the introduction portion side, as shown in FIG. 14, the metal plate is fed by the rotation of the upper die roller portion 2 and the lower die roller portion 3, and the shaping disc-like member 7. The crest portion 35a bites into the trough 45b side of the corresponding shaping disc-shaped member 14 with the metal plate interposed therebetween, and the crest portion 45a of the shaping disc-shaped member 14 corresponds to the corresponding shaping disc shape. It bites into the valley 35b of the member 7 and is gradually formed into a substantially sinusoidal waveform.
At the same time, as shown in FIG. 15, the wedge-shaped protrusions 41a of the drilling disk-like member 8 sandwiched between the shaping disk-like members 7 and 7 adjacent to each other are shaped circles adjacent to each other with the metal plate interposed therebetween. The corresponding perforated disc-like member 15 sandwiched between the plate-like members 14 and 14 bites into the concave portion 51b side, and the perforated disc-like member 15 has a wedge-shaped projection 51a corresponding to the corresponding perforated disc-like member 8. The concave portion 41b side is bitten, and a substantially rectangular through hole is gradually perforated. By using the wedge-shaped projections 41a and 51a, a planar projection is formed at the edge of the through hole.

Here, a pressing force is applied to the metal plate so that the portion pressed by the perforating disk-shaped members 8 and 15 is formed into a corrugated shape by the adjacent shaping disk-shaped members 7 and 14. At the same time, the intermediate portions 41c and 41d and the intermediate portions 51c and 51d are pressed so as to be formed into a corrugated shape.
In this way, the metal plate is continuously formed into a corrugated shape, and at the same time, a number of through-holes with surface protrusions are formed in the metal plate, and a corrugated metal plate 61 as shown in FIG. 16 is manufactured. This makes it possible to manufacture the same corrugated metal plate 61 at a speed approximately 5 times that of the conventional processing method in which the upper and lower molds are repeatedly pressed and separated.
In this example, as the material of the metal plate, for example, stainless steel (SUS304 (C: 0.08% or less, Si: 1.00% or less, Mn: 2.00% or less, P: 0.045% or less, S: 0.030% or less, Ni: 8.00% to 10.50%, Cr: 18.00% to 20.00%))).

As shown in FIGS. 16 and 17, the corrugated metal plate 61 is provided with a large number of rectangular through holes Ha, Hb,. The through-hole Ha is bent and protruded from the front surface to the back surface side at the edge portion, and has four planar protrusions pa, pa,. The through-hole Hb has four triangular planar protrusions pb, pb,... That are bent and protruded from the back surface toward the front surface side.
In this example, the dimensions of the wedge-shaped protrusions 41a and 51a are such that the average height H of the planar protrusions pa, pb,... Formed on the corrugated metal plate 61 and the concave and convex portions (rows) of the corrugated metal plate 61 The relationship between the average depth D of the concave portions) is set to 0.7D ≦ H ≦ 1.2D.

In this example, the through holes Ha and Hb of the corrugated metal plate 61 have a size of about 0.5 mm square. Further, the planar protrusions pa, pb,... Provided in the through holes Ha, Hb have substantially congruent triangular shapes.
The corrugated metal plate 61 having a large number of through holes is wound up by a winding device to form a spiral shape, and is used as a porous metal body constituting a metal filter 62 as shown in FIGS. .
Here, as shown in the figure, the corrugated metal plate 61 is wound up in a spiral shape in a state where the corrugated metal plate 61 is overlapped with a flat metal plate 63 having a plurality of through holes Ma, Ma,. The metal filter 62 is manufactured. In addition, the planar protrusions are not provided in the through holes Ma, Ma,.

The metal filter 62 is used for capturing and removing unburned particles in diesel exhaust gas discharged from, for example, a diesel engine.
Here, the through holes Ha, Hb, Ma, for example, enable the diesel exhaust particulates to move in the filter radial direction and have a function of increasing the filter collision probability and the residence time in the filter. Also, the planar protrusions pa and pb compensate for the reduction in the contact area of the fine particles due to the provision of the through holes Ha and Hb, increase the filter collision probability of the fine particles, block the straight movement of the fine particles, and the residence time in the filter Has the function of extending the length. In addition, when the planar protrusions pa and pb are accommodated in the concave portions of the corrugated metal plate 61, the planar protrusions pa and pb can be prevented from being deformed when the spiral protrusions are formed.

As described above, according to the configuration of this example, the metal plate is sandwiched from above and below between the upper die roller portion 2 and the lower die roller portion 3 so that the processing is continuously performed. Thus, since there is no reciprocating motion, it is possible to eliminate the wasteful time spent for pressing and separating the upper die and the lower die, so that the time required for processing can be shortened.
The upper mold body 9 (lower mold body 16) includes a plurality of shaping disk-shaped members 7, 7,... (14, 14,...) And drilling disk-shaped members 8, 8,. ,...), And so on, in particular, even when performing complex processing such as drilling a number of through holes and processing into a corrugated shape on a flat metal plate, Since a flat metal plate is processed into a corrugated shape in advance, drilling and processing into a corrugated shape can be performed at the same time without drilling a through hole, so that the time required for processing can be further shortened. . In addition, high accuracy can be maintained.

Further, since the metal plate can be sandwiched from above and below between the upper die roller portion 2 and the lower die roller portion 3 to smoothly process, the impact when the upper die and the lower die are pressed as in the prior art. Therefore, the wear of the blade edge can be suppressed, and the life of not only the mold but also the device itself can be increased.
The upper mold body 9 (lower mold body 16) includes a plurality of shaping disk-shaped members 7, 7,... (14, 14,...) And drilling disk-shaped members 8, 8,. ,...) Are laminated, the manufacturing cost of the molding die can be reduced as compared with the case where the die is manufactured by integral molding.
Further, for example, when a part of the cutting edge is damaged or when only a part of the blade is severely worn, the corresponding disk-shaped members 7 and 14 for drilling, Since only 15 need be exchanged, the maintenance cost can be reduced. Also, maintenance work can be reduced.
