Then, with reference to Fig. 4, the upper roll group 100 of metal plate perforation device and the concrete structure of lower rollers group 200 that form present embodiment are described in detail.Fig. 4 is (A) of the figure of perforated portion amplifying the metal plate perforation device representing present embodiment, Fig. 4 is amplify the side view representing perforated portion, and (B) of Fig. 4 is along the sectional view of the IVb-IVb line in Fig. 4 (A).
As (A) of Fig. 4, Fig. 4 (B) shown in, upper roll group 100 by forming like this, that is: is less than in the described perforation both sides of discoideus roller 10 bores a hole with side clearance roller 30,30 on a pair of the radius of discoideus roller 10 to link radius with this perforation mode that discoideus roller 10 is coaxial.In addition, lower rollers group 200 by forming like this, that is: between a pair deflector roll 40,40 to link with this pair deflector roll 40,40 coaxial modes the underside gap roller 50 that radius is less than the radius of deflector roll 40.In addition, as (A) of Fig. 4, Fig. 4 (B) shown in, make described upper roll group 100 relative with lower rollers group 200 with the discoideus roller 10 of the perforation of the upper roll group 100 when observing along the throughput direction of metallic plate 300 with the mode of deflector roll 40 in alternately shape arrangement of lower rollers group 200, thus form the perforated portion of the metal plate perforation device of present embodiment.
In addition, as (A) of Fig. 4, Fig. 4 (B) shown in, rotate by making upper roll group 100 and lower rollers group 200, and shearing force is produced between the perforation roller cutter portion 20 of the discoideus roller 10 of perforation forming upper roll group 100 and a pair deflector roll 40,40 forming lower rollers group 200, thereby, it is possible to utilize, being located at bores a hole bores a hole to metallic plate 300 continuously with multiple perforation roller cutter portions 20 of discoideus roller 10.
Wherein, in the present embodiment, as (A) of Fig. 4, Fig. 4 (B) shown in, upper roll group 100 is made up of with side clearance roller 30,30 in discoideus roller 10 and a pair perforation, lower rollers group 200 is made up of underside gap roller 50 and a pair deflector roll 40,40, but such as, also can be as shown in Figure 5, upper roll group 100 is by alternately configuring the discoideus roller 10 of multiple perforation and multiple upper side clearance roller 30 forms, and lower rollers group 200 is by alternately configuring multiple deflector roll 40 and multiple underside gap roller 50 forms.In this case, boring a hole is not particularly limited by discoideus roller 10 and the quantity of upper side clearance roller 30 and the quantity of deflector roll 40 and underside gap roller 50, as long as combine the quantity in the hole for being formed at metallic plate 300 and suitably determine.In addition, in this case, preferably, perforation residual fraction removing member 80 gap described later of the quantity corresponding with the quantity of underside gap roller 50 is set.In addition, such as, (A) of Fig. 4, Fig. 4 (B) shown in form in, the perforated metal in a hole can be had in the direction of the width, in addition, when the form shown in Fig. 5, the perforated metal in 4 holes can be had in the direction of the width.In addition, in the form shown in Fig. 5, the each perforation forming upper roll group 100 is formed at the perforation roller cutter portion 20 of discoideus roller 10 position can bored a hole to metallic plate 300 at synchronization, but also can adopt the form that the position in perforation roller cutter portion 20 offsets one from another.
In addition, as shown in Figure 6, the metal plate perforation device of present embodiment comprises the perforation residual fraction removing member 80 being positioned at the direction of rotation downstream leaning on lower rollers group 200 than perforated portion, and this perforation residual fraction removing member 80 is for removing the perforation residual fraction (perforation residue) produced when utilizing 20 pairs, perforation roller cutter portion metallic plate 300 to bore a hole.At this, (A) of Fig. 6 is the lower rollers group 200 of the metal plate perforation device representing present embodiment and the side view of perforation residual fraction removing member 80, and (B) of Fig. 6 is along the sectional view of the VIb-VIb line in Fig. 6 (A).As (A) of Fig. 6, Fig. 6 (B) shown in, perforation residual fraction removing member 80 is the tabular components with the thickness roughly the same with the thickness of the underside gap roller 50 forming lower rollers group 200, when observing along the thickness direction of perforation residual fraction removing member 80, this perforation residual fraction removing member 80 has with the top ends that the mode of narrowed width comes to a point along with going towards top.Further, residual fraction removing member 80 of boring a hole configures with following state: in the face being formed top ends, the first surface 81 of side is the tangential direction of the circumference along underside gap roller 50, and the second face 82 of opposite side is toward the outer side.
In addition, in the present embodiment, when the perforation residual fraction (perforation residue) produced when utilizing 20 pairs, perforation roller cutter portion metallic plate 300 to bore a hole is fallen on underside gap roller 50, owing to being provided with such perforation residual fraction removing member 80, thus suitably can remove from underside gap roller 50 the perforation residual fraction fallen on underside gap roller 50 in gap.
Specifically, the perforation residual fraction (perforation residue) produced when utilizing 20 pairs, perforation roller cutter portion metallic plate 300 to bore a hole is fallen on underside gap roller 50, this perforation residual fraction (perforation residue) along with the rotation of underside gap roller 50, moves to direction of rotation downstream and is removed from underside gap roller 50 under the effect of the centrifugal force of the rotation of gap roller 50 as shown in the thick arrow in (A) of Fig. 6.But, on the other hand, part perforation residual fraction is not removed and arrives the forming position of perforation residual fraction removing member 80 under the effect of the centrifugal force rotated, adopt present embodiment, even such part perforation residual fraction be not removed under the effect of the centrifugal force rotated, under the effect of perforation residual fraction removing member 80, also can suitably remove.
Particularly, when not arranging perforation residual fraction removing member 80, because such part perforation residual fraction be not removed under the effect of the centrifugal force rotated is not removed from underside gap roller 50, therefore this part perforation residual fraction rotates and again turns back to perforated portion together with underside gap roller 50.So, in this case, under the impact remaining in the perforation of the part on underside gap roller 50 residual fraction, perforation precision when utilizing 20 pairs, perforation roller cutter portion metallic plate 300 to bore a hole obviously reduces, as a result, the precision in the hole formed on the perforated metal obtained is caused to reduce.Particularly, be about 0.02mm ~ 0.2mm when using thickness, when especially the metallic plate of the thickness filming that is below 0.1mm is used as metallic plate 300, the weight of perforation residual fraction also trends towards lightweight, therefore, under the effect of electrostatic force etc., the tendency that such perforation residual fraction remains on underside gap roller 50 is always higher, and such problem becomes obvious.To this, in the present embodiment, by arranging perforation residual fraction removing member 80, thus such problem can effectively be prevented.
Then, the piercing process using the metal plate perforation device of present embodiment to bore a hole to metallic plate 300 is described with reference to Fig. 7.
In the present embodiment, as shown in Figure 3, rotate while make upper and lower a pair jockey pulley 60a, 60b and upper and lower a pair jockey pulley 70a, 70b rotate along the direction in figure shown in arrow by making upper roll group 100 and lower rollers group 200 along the direction in figure shown in arrow, thus, metallic plate 300 is passed through continuously between upper roll group 100 and lower rollers group 200, thus utilizes the perforation roller cutter portion 20 being located at the discoideus roller 10 of perforation of upper roll group 100 to bore a hole to metallic plate 300 continuously.
Now, first, as shown in (A) of Fig. 7, roughly side by side to be nipped metallic plate 300 and form joint-cutting by the front nose part 21 and rear end side nose part 22 making the formation perforation roller cutter portion 20 of the discoideus roller 10 of perforation.Wherein, in the present embodiment, by making the sword of front nose part 21 height high in the sword of rear end side nose part 22, thus can obtain making front nose part 21 and rear end side nose part 22 roughly side by side to nip the structure of metallic plate 300 as shown in (A) of Fig. 7.In addition, in (D) of (A) ~ Fig. 7 of Fig. 7, on the upside of accompanying drawing, represent the state near perforated portion, and on the downside of accompanying drawing, represent the appearance of metallic plate 300 now.
Then, the discoideus roller 10 of perforation is made to continue to rotate along the direction in figure shown in arrow, then bore a hole as shown in (B) of Fig. 7 with roller cutter portion 20 extend from front nose part 21 and rear end side nose part 22 respectively, the part of lateral margin nips metallic plate 300, and the joint-cutting being formed at metallic plate 300 extended.
Afterwards, the discoideus roller 10 of perforation is made to continue to rotate along the direction in figure shown in arrow, under the effect of the shearing force then produced at lateral margin and the deflector roll 30 (not shown) by perforation roller cutter portion 20, the joint-cutting being formed at metallic plate 300 extends further, as shown in (C) of Fig. 7, when perforation arrives the center of the perforated portion of metal plate perforation device with the center in roller cutter portion 20, form the hole of rectangle.
Then, make the discoideus roller 10 of perforation continue to rotate along the direction in figure shown in arrow, then bore a hole as shown in (D) of Fig. 7 and to extract from the metallic plate 300 being formed with rectangular opening with roller cutter portion 20.In addition, fall after on underside gap roller 50 at the perforation residual fraction produced because of perforation, a part for this perforation residual fraction is removed under the effect of the centrifugal force of underside gap roller 50, and the remainder of this perforation residual fraction is removed under the effect of perforation residual fraction removing member 80.
As described above, the metal plate perforation device of present embodiment is used to bore a hole to metallic plate 300 continuously.
According to the present embodiment, as (A) of Fig. 6, Fig. 6 (B) shown in, perforation residual fraction removing member 80 is provided with, therefore, it is possible to suitably remove the perforation residual fraction (perforation residue) produced when utilizing 20 pairs, perforation roller cutter portion metallic plate 300 to bore a hole leaning on the position in the direction of rotation downstream of lower rollers group 200 than perforated portion.So, thereby, it is possible to effectively solve such problem: perforation residual fraction rotates and again turns back to perforated portion together with underside gap roller 50, and thus, perforation precision when utilizing 20 pairs, perforation roller cutter portion metallic plate 300 to bore a hole obviously reduces.Particularly, be about 0.02mm ~ 0.2mm when using thickness, when especially the metallic plate of the thickness filming that is below 0.1mm is used as metallic plate 300, the weight of perforation residual fraction also trends towards lightweight, therefore, under the effect of electrostatic force etc., the tendency that such perforation residual fraction remains on underside gap roller 50 is always higher, and such problem trends towards obviousization.To this, adopt present embodiment, by arranging perforation residual fraction removing member 80, thus can effectively solve such problem, when the metallic plate 300 that the metallic plate 300, the particularly thickness that to thickness are about 0.02mm ~ 0.2mm are below 0.1mm is bored a hole, also can bore a hole to metallic plate 300 well, thereby, it is possible to wear many same holes continuously with high accuracy.
And, adopt present embodiment, multiple perforation roller cutter portion 20 is circumferentially formed with on discoideus roller 10 with being separated with predetermined distance with the state outstanding to radial outside in perforation, when observing this perforation roller cutter portion 20 from the side, this perforation roller cutter portion 20 has V-shape, and make the sword of front nose part 21 height high in the sword of rear end side nose part 22, thus can obtain making front nose part 21 and rear end side nose part 22 roughly side by side to nip the structure of metallic plate 300 as shown in (A) of Fig. 7.So, thus, with front nose part 21 individually or rear end side nose part 22 nip individually metallic plate 300 situation compared with, can abirritation in the stress of metallic plate 300, result, can suppress the distortion of the perforated metal obtained.
