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; Through the pressure pad 5 of elastic component 4 under patrix fixture 2 suspension; 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 the 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 through 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 is 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, and the radius of cylindrical part 43 is r3 (=D3 * 1/2); The length of cylindrical part 43 is h; The thickness of treating die-cut metallic plate 8 is t, then r3＜r1-r2, and h＞t+r3.
The end face 60 that constitutes the frustum outer surface extends into axis 31 inclinations with respect to drift 13, 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 with the inclination mode is connected with the inner peripheral surface that extends in parallel 63 each other 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.Through 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 through the clamping between counterdie 9 and the pressure pad 5.Simultaneously, sliding part 12 is by pressing plate 3 pressurizations, and drift 13 combines pressing down of sliding part 12 and descends.When drift 13 descends, as shown in Figure 6, through the tapering part 45 of protuberance 27, thereafter,, perforation 71 is formed in the metallic plate 8 through cylindrical part 43.In such situation, wherein, the motion of metallic plate 8 receives cylindrical part 43 restrictions that are inserted in 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, and is as shown in Figure 7, thus; The metallic plate 8 that contacts with the annular surface 33 of circular end surface 26 is by annular surface 33 pressurization, and combines the decline of punch body 25 and descend.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; Draged by the die edge 67 of curved surfaces of circular end surface 26 34 and mould 10 and to draw and elongate; And metallic plate 8 combines shearing force thereafter, and quilt is torn and broken on die edge 67 sides of mould 10, and is 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 through circular port 65, and is as shown in Figure 9; Therefore, through hole 72 is formed in the metal forming 8.

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 cooperates with curved surfaces 34, and 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 possibly 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 circular base plane 41 and the annular surface 33 that extends perpendicular to axis 31 of the cylindrical part 43 of protuberance 27, also can be fixed on the nose circle face 26 of punch body 25 with enough width.Therefore, through 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 the mould with inclined end face 60 10, 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 through movable punching head 13 vertically, but through hole 72 can be formed in the sloping portion of metallic plate 8 also through movable punching head 13 obliquely.
For above-mentioned mould 10, although the die edge 67 of realizing having acute angle, theta with end face 60, said end face 60 extends with respect to the axis 31 of drift 13 obliquely; But also can provide a kind of structure to replace, or combine with it, shown in figure 10; Axis 31 through with respect to drift 13 extends obliquely; Make inner peripheral surface 63 form the inner surface of frustum, end face 60 is connected with inner peripheral surface 63 each other 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 shown in figure 11, or Long Circle 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 a kind of structure can be provided; 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 descended after through hole 72 forms, die-cut waste material 64 was 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 draw and promote owing to draging of drift 13.
