The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.
Referring to Fig. 1 and Fig. 2, the punching riveting die of exempting from of the present utility model comprises cope match-plate pattern 1 and lower bolster 2, and cope match-plate pattern 1 is used for fixedly patrix drift 3, and lower bolster 2 is used for fixedly counterdie drift 4.In view of riveted construction mostly is circular, patrix drift 3 and counterdie drift 4 in the utility model all are preferably rotary structure, perhaps are being used for that riveted material 9 is realized that the part of riveted joint forms rotary structure at least.Certainly, this structure is a kind of preferred, as long as can realize that the structure of riveted all should be worked as belongs to protection domain of the present utility model, does not give unnecessary details herein.In addition, in the utility model " on ", D score do not limit practical structures of the present utility model, the bearing change that carries out as the basis take this structure all belongs to protection domain of the present utility model.
Need to prove that the state that is in when finishing riveted when cope match-plate pattern 1 and lower bolster 2 is called the matched moulds state; When being in the state that is separated from each other and riveted material 9 is not applied active force, cope match-plate pattern 1 and lower bolster 2 be called general state.
Wherein, patrix drift 3 is fixed in the cope match-plate pattern 1, the bottom of patrix drift 3, and namely an end of the lower surface of close cope match-plate pattern 1 forms the upper riveted face 5 of level, has wherein formed a upper riveted projection 6 under the mind-set.Particularly, riveted projection 6 comprises vertical side and the bottom surface of level, for prevent 6 pairs of riveted materials 9 of upper riveted projection do the time spent part of riveted material 9 push thin, the location optimization employing round-corner transition that joins in side and bottom surface.
Counterdie drift 4 is fixed in the lower bolster 2, the top of counterdie drift 4, namely an end of the upper surface of close lower bolster 2 forms the lower riveted face 7 of level, wherein form a lower riveted projection 8 under the mind-set, particularly, lower riveted projection 8 comprises vertical side and the end face of level, for prevent 8 pairs of riveted materials 9 of lower riveted projection do the time spent part of riveted material 9 push thin, the location optimization employing round-corner transition that joins on side and top.
By on address in conjunction with Fig. 1 to Fig. 4, we have understood the basic structure of exempting from the punching riveting die of the present utility model, in fact, in the riveted operation, be from relative both direction riveted material 9 to be applied active force with counterdie drift 4 by patrix drift 3, that is to say, 4 pairs of riveted materials 9 of counterdie drift apply active force upwards, and 3 pairs of riveted materials 9 of patrix drift apply downward active force, make riveted material 9 that deformation occur, be in fact with in another riveted material 9 of riveted material 9 parts " embedding ", thereby realize reliable riveted.
For with in another riveted material 9 of a riveted material 9 " embedding ", as shown in Figure 3 and Figure 4, upper riveted face 5 is greater than lower riveted face 7, and namely d2 is greater than d1, and the horizontal cross-section of upper riveted projection 6 is greater than the horizontal cross-section of lower riveted projection 8.Need to prove that upper riveted face 5 is preferably identical with the shape of lower riveted face 7, upper riveted projection 6 is also preferably identical with the shape of lower riveted projection 8.
In order to realize the matched moulds state, as a kind of preferred version, patrix drift 3 is fixed in the cope match-plate pattern 1 and relative sliding can not occur for both, and counterdie drift 4 is fixed in the lower bolster 2 and both can slide up and down relatively.
So, the detailed process of riveted operation is as follows: as shown in Figure 2, on 9 placements of riveted material and locator lower bolster 2, it is close to riveted material 9 together that cope match-plate pattern 1 drives patrix drift 3, when cope match-plate pattern 1 touches riveted material 9, namely riveted material 9 and lower bolster 2 applied active force, 2 of lower bolsters move downward, until arrive the matched moulds state, namely state shown in Figure 1 is finished the riveted operation.A baffle plate is set below lower bolster 2, the position of lower bolster 2 is limited; Can also between lower bolster 2 and baffle plate, set elastomeric element, so that lower bolster 2 can automatically reset under the general state, thereby play the effect of protecting counterdie drift 4.In the whole riveted operation, riveted material 9 can not slide, and can realize exactly riveted joint.
When riveting die is in the matched moulds state, namely during state shown in Figure 1, the bottom of upper riveted projection 6 namely is no more than the lower surface of cope match-plate pattern 1 near an end of the lower surface of cope match-plate pattern 1; The top of lower riveted projection 8, namely an end of the upper surface of close lower bolster 2 exceeds the upper surface of lower bolster 2; Simultaneously, the upper surface of lower riveted face 7 also can exceed the upper surface of lower bolster 2, helps to make riveted tightr.
For riveted material 9 is riveted together more reliably, as a kind of preferred version, when being in the matched moulds state, lower riveted projection 8 exceeds the distance of lower bolster 2 upper surfaces greater than the thick t of material of riveted material 9, and upper riveted face 5 is apart from the distance of the lower surface of the cope match-plate pattern 1 thick t of material less than riveted material 9.
As a kind of preferred version, the gap between the edge of the edge of upper riveted face 5 and lower riveted face 7, namely 60% of the monolateral gap P thick t of material that is riveted material 9, that is: P=60%*t, and P=(d2-d1)/2.Determined that in case expect thick t then monolateral gap P has also just determined thereupon, that is to say that for the thick riveted material 9 of difference material, the mould that adopts is not identical.In the utility model, patrix drift 3 can take out from cope match-plate pattern 1, and counterdie drift 4 can take out from lower bolster 2, and the thick riveted material 9 of the different material of riveted only need to replace with stamping head 3 and counterdie drift 4 gets final product, Effective Raise the versatility of mould.
Above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in the protection domain of the present utility model.
