In Fig. 1 to 5, comprise patrix fixture 2 according to the metallic plate blanking units 1 of this embodiment, it is by hydraulic cam and suchlike members uplift and decline; Be fixed to the pressing plate 3 of patrix fixture 2; Pressure pad 5 under hanging from patrix fixture 2 by elastic component 4; Drift fixture 7, it is constructed to the punch units that is fixed to pressure pad 5 by means of bolt 6 grades; Counterdie 9 is waited to stand die-cut metal sheet 8 and is placed on this counterdie; And be embedded in mould 10 in the counterdie 9.
Sliding part 12 has depression 21, and is suitable for being fixed in depression 21 places cooperation one detent pin 22 of shell 11, so that sliding part 12 does not break away from shell 11 because of the elastic force of helical spring 14.When patrix fixture 2 descended, sliding part 12 was suitable for being pressed down by pressing plate 3.
Being used for the drift 13 of die-cut metallic plate 8 comprises and forms columniform punch body 25; Be formed on the circular end surface 26 of punch body 25---promptly, an end face---on protuberance 27; And the circular end surface 28 that is arranged on punch body 25 integratedly---promptly, the other end---on the axle collar 29.
In above-mentioned drift 13, if the radius of supposition punch body 25 is r1 (=D1 * 1/2), the radius of curvature of curved surfaces 34 is r2, the radius of cylindrical part 43 is r3 (=D3 * 1/2), the length of cylindrical part 43 is h, the thickness for the treatment of die-cut metallic plate 8 is t, then r3＜r1-r2, and h＞t+r3.
The axis 31 that the end face 60 of formation frustum outer surface extends into respect to drift 13 tilts, and the inner peripheral surface 63 that constitutes cylindrical surface is parallel to axis 31 extensions of drift 13.The end face 60 that extends in the inclination mode is connected each other with the inner peripheral surface 63 that extends in parallel with adjoining, forms acute angle theta at opening 61 places of the circular port 62 of end face 60.Therefore, mould 10 has die edge 67, and it has acute angle theta at opening 61 places.
The diameter D1 of circular end surface 26 is not less than 0.8 to the ratio D1/D4 of the diameter D4 of circular port 62, be assumed to t if treat the thickness of die-cut metallic plate 8, then poor (gap) f between the radius r 4 (=D4 * 1/2) of the circular port 62 of radius r 1 of circular end surface 26 (=D1 * 1/2) and mould 10 is not less than 0.15t, and is not more than 2mm.By being equipped with and being fixed on outer peripheral surface 66 places, mould 10 is embedded in the counterdie 9.
In above-mentioned blanking units 1, when pressing plate 3, pressure pad 5 and drift fixture 7 descend along with the decline of patrix fixture 2, be placed on metallic plate 8 pressurized pad 5 pressurizations on the counterdie 9, and be fixed by the clamping between counterdie 9 and the pressure pad 5.Simultaneously, sliding part 12 is pressurizeed by pressing plate 3, and drift 13 descends in conjunction with pressing down of sliding part 12.When drift 13 descends, as shown in Figure 6,, thereafter,, perforation 71 is formed in the metallic plate 8 by cylindrical part 43 by the tapering part 45 of protuberance 27.In such circumstances, wherein, the motion of metallic plate 8 is subjected to being inserted in cylindrical part 43 restrictions of the protuberance 27 in the perforation 71, drift 13 continues to descend, the punch body 25 of drift 13 is inserted in the circular port 62 of mould 10, as shown in Figure 7, and thus, the metallic plate 8 that contacts with the annular surface 33 of circular end surface 26 is pressurizeed by annular surface 33, and descends in conjunction with the decline of punch body 25.In this descends, metallic plate 8 is its that part of between the die edge 67 of the curved surfaces 34 of circular end surface 26 and mould 10, by die edge 67 pullings and the elongation of the curved surfaces 34 of circular end surface 26 and mould 10, and thereafter metallic plate 8 in conjunction with shearing force, on die edge 67 sides of mould 10, be torn and break, as shown in Figure 8.After metallic plate 8 broke on die edge 67 sides of mould 10, drift 13 rose, and simultaneously die-cut waste material 64 is discharged by circular port 65, as shown in Figure 9; Therefore, through hole 72 is formed in the metal forming 8.
Incidentally, in mould 10, because end face 60 adjoins mutually to be connected with inner peripheral surface 63 and is embodied as acute angle theta, promptly, because the die edge 67 of mould 10 has acute angle theta, so under punch body 25 cooperations of metallic plate 8 and drift 13 when punched, the part place that adjoins connection mutually that between end face 60 and inner peripheral surface 63, has acute angle theta, concentrated stress is formed in the metallic plate 8 greatly.Its result can suppress near the elongation of the metallic plate 8 the die edge 67 as much as possible, and the part place that adjoins connection mutually between end face 60 and inner peripheral surface 63 can accurately die-cut metallic plate 8 down.Therefore, not only be no more than the metallic plate of 0.8mm but also be 0.8mm or above metallic plate, can realize the die-cut of metallic plate, simultaneously, be enough to avoid the generation of burr for thickness of slab for thickness of slab.
In addition, in metallic plate 8, realize die-cut blanking units 1 for being suitable for, this metallic plate 8 has the end face 60 and inner peripheral surface 63 cooperations of acute angle theta with adjoining with being connected each other, and with curved surfaces 34 cooperations, protuberance 27 has cylindrical part 43, cylindrical part 43 is arranged on the annular surface 33 of punch body 25 integratedly, and has circular base plane 41 and circular top plane 42.Therefore, even the cone angle of the far-end of the tapering part 45 of protuberance 27 is done very greatly and may be obtained enough intensity and durability,, whole protuberance 27 can prevent that protuberance 27 breaks away from perforation 71 even doing very highly formed perforation 71 by protuberance 27 after, then surround the circular base plane 41 of cylindrical part 43 of protuberance 27 and the annular surface 33 that extends perpendicular to axis 31, also can be fixed on the nose circle face 26 of punch body 25 with enough width.Therefore, by the die edge 67 that centers on mould 10 with the punch body 25 cooperation metallic plate 8 that breaks reliably, can in metallic plate 8, form through hole 72 accurately.In addition, because curved surfaces 34 has the radius of curvature r2 of 0.1mm to 5mm,, simultaneously, reduce to cause the shearing effect of burr reason so metallic plate 8 can stand tensile fracture more satisfactorily.In addition, because ratio D1/D4 is not less than 0.80, and difference f is not less than 0.15t, so, except some shearing force, can mainly cause tensile fracture, thus, formation through hole 72 metallic plate 8 in effectively.
According to mould 10 with inclined end face 60, needn't further handle end face 60 according to the shape of metallic plate 8, thus, can reduce cost.
For blanking units 1, form through hole 72 by movable punching head 13 vertically, but through hole 72 can be formed in the sloping portion of metallic plate 8 also by movable punching head 13 obliquely.
For above-mentioned mould 10, although realize having the die edge 67 of acute angle theta with end face 60, described end face 60 extends obliquely with respect to the axis 31 of drift 13, but also can provide a kind of structure to replace, or combine, as shown in figure 10 with it, extend obliquely by axis 31 with respect to drift 13, make inner peripheral surface 63 form the inner surface of frustum, end face 60 is connected each other with inner peripheral surface 63 with adjoining, forms acute angle theta at opening 61 places of the circular port 62 of end face 60.In this case, end face 60 can extend perpendicular to the axis 31 of drift 13.
Although the opening in the foregoing description 61 forms circle, but also can provide a structure to replace it, opening 61 can form the quadrangle of bight rounding as shown in figure 11, or Long Circle as shown in figure 12, or such as ellipse, triangle, rectangle or polygonal other shape.
In addition, for the mould in the foregoing description 10, circular port 65 forms with circular port 62 continuous, but also can provide a kind of structure, as shown in figure 13, so that diameter only is slightly less than the circular port 75 of circular port 62 diameters is concentric with circular port 62, and has a diameter bigger than punch body 25 diameters, circular port 75 is plugged between circular port 62 and the circular port 65.In this case, when drift 13 descends after through hole 72 forms, die-cut waste material 64 is pushed out circular port 75, after die-cut waste material 64 is pushed out circular port 75, when drift 13 promotes, die-cut waste material 64 is caught by the inner peripheral surface 76 of the qualification circular port 75 of mould 10, so die-cut waste material 64 can be discharged circular port 75 reliably, and can not promote owing to the pulling of drift 13.
