Detailed description of the invention
Below in conjunction with accompanying drawing, enforcement the specific embodiment of the present invention is described in detail.
Refer to shown in Fig. 1, for implementing the cross-sectional schematic of diel of the present invention when original state, execute diel of the present invention for the multiple hole of punching press on product material strip, spacer ribs (non-label) is provided with between the plurality of hole, this diel comprises upper module 10 and lower module 11, wherein upper module 10 comprises upper die plate 100, upper bolster 101, guide pin fixed head 102, stripper plate 103, and lower module 11 comprises lower bolster 111 and die shoe 110, wherein be provided with spring 105 between guide pin fixed head 102 and stripper plate 103, and product material strip 12 is placed between stripper plate 103 and lower bolster 111, and by upper, lower module 10, 11 are closely affixed (as shown in Figure 3) and are firmly compressed between stripper plate 103 and lower bolster 111 by this product material strip 12, and this diel is provided with a decompressor (non-label), red needle 13 is made relatively to go up after being driven, lower module 10, 11 move and punching products material strip 12 (as shown in Figure 4).
In the specific implementation, this decompressor comprises a red needle fixed head 131 and red needle backing plate 130, this red needle fixed head 131 is mounted on red needle backing plate 130, and red needle 13 is groups is located on red needle fixed head 131, and this red needle fixed head 131 and red needle backing plate 130 are located in the middle of upper die plate 100, and be connected with upper bolster 101 by spring 132, this red needle backing plate 130 is connected with the driving mechanism (not shown) of this decompressor, under the driving of driving mechanism, spring 132 is compressed, thus make red needle fixed head 131 and red needle backing plate 130 move, thus drive red needle 13 motion punching products material strip 12.
In addition, this upper die plate 100, upper bolster 101 and guide pin fixed head 102 are under the driving of the drive unit of this diel, to lower bolster 111 direction motion also Compress Spring 105, make stripper plate 103 and guide pin fixed head 102 fit tightly, and product material strip 12 is firmly compressed between stripper plate 103 and lower bolster 111.Or, also the drive unit of this diel can be made to drive this die shoe 110 to move to stripper plate 103 direction under the driving of the drive unit of this diel with lower bolster 111, and the spring 105 compressed between stripper plate 103 and guide pin fixed head 102, make stripper plate 103 and guide pin fixed head 102 fit tightly, and product material strip 12 is firmly compressed between stripper plate 103 and lower bolster 111.
In addition, this diel is also provided with guide pin 104 on guide pin fixed head 102, is provided with corresponding pilot hole 112 accordingly at lower bolster 111 and die shoe 110.Meanwhile, lower bolster 111 with on die shoe 110 also corresponding red needle 13 be provided with material-dropping hole 113, these structures above-mentioned to be in diel conventional structure, no longer describe in detail herein.
Moreover, the hydraulic means or other frame for movement that match with this diel is can be as the drive unit of driving die shoe 110, red needle backing plate 130 and upper die plate 100 mentioned in describing above, this structure in the prior art more description, also no longer describes in detail herein.
During hole multiple for punching on product material strip 12, be out of shape when punching press adjacent holes for preventing the spacer ribs between adjacent holes, this diel is also provided with packed column 106, this packed column 106 parallels setting with red needle 13, this packed column 106 is arranged on guide pin fixed head 102, when stripper plate 103 and guide pin fixed head 102 fit tightly and are firmly compressed between stripper plate 103 and lower bolster 111 by product material strip 12, this packed column is to pass in type hole on product material strip 12 close to gapless state and to penetrate in lower bolster 111, namely the outer wall of this packed column 106 and the edges close of this hole are conflicted, when so preventing red needle 13 punching products material strip 12, spacer ribs between hole is out of shape to the center position of packed column 106, add, lower module 10, the pressure of the vertical direction of 11, thus the deformation power of punching products material strip 12 generation can be offset.Accordingly, this lower bolster 111 is provided with the groove 114 holding this packed column 106 one end.
Detailed process when punching press is carried out in the diel of using the present invention to disclose can be joined shown in Fig. 1 to Fig. 4, and wherein Fig. 1 is original state, i.e. die opening state.In this case, product material strip 12 can be placed on lower bolster 111.Afterwards as shown in Figure 2, this upper module 10 and lower module 11 matched moulds, make product material strip 12 be positioned between stripper plate 103 and lower bolster 111.Afterwards as shown in Figure 3, upper die plate 100, upper bolster 101 and guide pin fixed head 102 are under the driving of the drive unit of this diel, to lower bolster 111 direction motion also Compress Spring 105, make stripper plate 103 and guide pin fixed head 102 fit tightly, and product material strip 12 is firmly compressed between stripper plate 103 and lower bolster 111.Last this red needle backing plate 130, with under the driving of the driving mechanism of this decompressor, makes red needle fixed head 131 and red needle backing plate 130 move to lower bolster 111 direction as shown in Figure 4, thus drives red needle 13 motion punching products material strip 12.Certainly, the product material strip 12 shown in above-mentioned Fig. 2 and Fig. 3 is located and is also driven die shoe 110 and lower bolster 111 to move to stripper plate 103 direction by drive unit with fixing process and realize, and concrete principle is the same, no longer describes in detail herein.
Compared with prior art, implement diel of the present invention by arranging the packed column paralleled with a red needle, before red needle punching products material strip, this packed column passes in type hole on product material strip and penetrates in lower bolster, and the edges close of the outer wall of this packed column and this hole is conflicted, spacer ribs when so preventing red needle punching products material strip between hole occurs collapsing the problems such as the flatness that angle, torsional deformation, die-cut material deformation produce is poor, Stress non-homogeneity.Implement diel of the present invention by upper simultaneously, lower module closely cooperates and is firmly compressed between stripper plate and lower bolster by product material strip, carry out die-cut by decompressor to product material strip again, thus avoid existing diel stripper plate when punching press to depend merely on spring pressure compacted products material strip, when die-cut, cause stripper plate pressure to put not tight product material strip because die-cut material deformation makes spring pressure change, ensure that product material strip there will not be above-mentioned angle of collapsing after die-cut especially, torsional deformation, the flatness that die-cut material deformation produces is poor, the problems such as Stress non-homogeneity.
Be understandable that, for those of ordinary skills, can be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, and all these change or replace the protection domain that all should belong to the claim appended by the present invention.
