Preferential embodiment is detailed to be situated between:
Below in conjunction with accompanying drawing one embodiment of the invention are described.
Fig. 1 is a partial cut away side views of using the hole punched device of hole-punching method of the present invention.Hole punched device among the figure comprises a die shoe 1, that column 3 on the die shoe 1 is supported by cover compression spring 4 thereon by being anchored on, and can vertically upper and lower mobile upper bolster 2, be fastened on the punch die that is drilled with through hole 5a 5 on the die shoe 1, and the drift 6 that is anchored on upper bolster 2, the latter is corresponding with the through hole in the punch die 5 with the pressed sheet 8 that drift 6 is fixed in its relevant position by means of backing plate 7.Blank compressing member 9 is fixed on the lower end of each suspension rod 10 that hangs on upper bolster 2, has pilot hole 9a on the blank compressing member 9, and the corresponding through hole 5a in they and the punch die aligns.Electrical equipment is placed between punch die 5 and the compressing member 9 with laminate 11, and compressor arm 12 passes upper bolster 2, backing plate 7 and pressed sheet 8, and its end props up compressing member 9.
When the hole punched device stated of chatting face to face in the use carries out the punching of laminate 11, this hole punched device is fastened on the table top (not shown) of stamping machine the required stamping press F of punching on laminate 11 1Act on the upper bolster 2, simultaneously with thrust F 2Put on the compressor arm 12.At above-mentioned thrust F 2 Effect compressing member 9 down is pressed under the condition of laminate 11, and drift 6 is at punching power F 1Effect under pass the logical laminate 11 of guide hole 9a backlash on the compressing member 9, and then penetrate the through hole 5a in the punch die 5.So just gone out the hole of preliminary dimension in laminate 11 at electrical equipment.
The present invention is not subjected to the influence of any device of exerting pressure, any pressue device, and for example the two action stamping machines of oil pressure type need only it and can apply punching shear F 1With thrust F 2, can use.
In the above-described embodiment, be transferred to 0 kgf/millimeter in the surperficial thrust that acts on the compressing member 9 2Condition under, when changing the diameter d of institute's punching and electrical equipment with the ratio d/t between the thickness t of laminate 11, crackle 14 has as shown in Figure 2 appearred in the thickness direction along laminate 11 around the hole of going out 13.Crackle 14 makes laminate 11 become substandard products, because they have reduced the electric property of laminate, especially they have reduced the insulaion resistance between the adjacent holes 13,13 on the laminate 11 and can cause the short circuit of wiring closet on the laminate.
Be shown in Fig. 3 in the result of study that cracks 14 reason that is intended to find out of carrying out aspect each details of punch process, it show when the d/t ratio of laminate hour, the horizontal direction of laminate or horizontal material amount of flow 15 are bigger, and the height that increases the annular flange 16 around each hole 13 along with the cross-current momentum of material also becomes big.Found thus each go out hole 13 around because pouring of drift 6 acts on the circumferential stress σ produce θAlso bigger, thus produced perpendicular to stress σ θBreak, form above-mentioned crackle 14(Fig. 2).
As for the measure that prevents that should take at above-mentioned crackle, think to blank compressing member 9 exert pressure make its be pressed in electrical equipment with laminate 11 on, do not allow bead 16 arch upward can to reduce the circumferential stress σ that cracks effectively θ
To using drift 6 14(Fig. 2 that cracks of the hole punched device among Fig. 1) the unidirectional gap between drift 6 and the punch die 5 remained in the research carried out under 5% the condition and change thrust F 2, obtained result as shown in Figure 5.
The abscissa of Fig. 5 is the applanation (q) that applied of blank compressing member and the tensile strength sigma of blank BRatio, ordinate then is the ratio between the thickness (t) of the aperture (d) in the hole of going out 13 when crackle occurring between adjacent holes and laminate 11.Article three, curve A ((P-d/2)/(d/2)=3.0), B((P-d/2)/(d/2)=4.0) and C((P-d/2)/(d/2)=5.0) incidence of crackle represented respectively.The applanation of q(compressing member above-mentioned) is thrust F 2Divided by the contact area of printed panel 11 with compressing member 9, P then is the pitch between two adjacent holes 13,13.
In addition, also to use towards electrical equipment with of laminate have 1 millimeter high and diameter as D and with blank compressing member 17(Fig. 6 of the concentric annular raised face 17b of guide hole 17a) cracking frequency when blank applies constant, 20% the applanation that is equivalent to printed panel tensile strength studies, the variable during research is diameter D.
Research the results are shown in Fig. 7, its ordinate is cracking frequency (%), abscissa is the external diameter (D) of the annular excrescence on the compressing member and the ratio of guide hole diameter (d), has expressed on compressing member 17 area of exerting pressure with laminate 11 to the electrical equipment influence to cracking frequency among the figure.The applanation that curve E((compressing member from Fig. 7 applies)/and (tensile strength)=0.2) can clearly be seen that, the radius of the area of on the compressing member laminate being exerted pressure should be equivalent to the twice of the radius in the hole that each is gone out in the laminate at least, the compressing member applied pressure then will be equal to or greater than 20% of laminate tensile strength, could prevent the generation of crackle effectively.
As mentioned above, the method according to this invention, punching can at room temperature be carried out, the shrinkage of the centre-to-centre spacing of the Kong Yukong that the zone of heating pressing plate causes during punching like this just can be avoided fully, in the punch process this electrical equipment with laminate between the adjacent hole issuable crackle also can prevent, like this, the degree of accuracy of the size in hole and productivity ratio can improve.
