Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
See Fig. 1 and Fig. 2, punching riveting die of exempting from of the present invention comprises cope match-plate pattern 1 and lower bolster 2, and cope match-plate pattern 1 is for fixing patrix drift 3, and lower bolster 2 is for fixing counterdie drift 4.In view of riveted construction mostly is circular, the patrix drift 3 in the present invention and counterdie drift 4 are all preferably rotary structure, or at least form rotary structure in the part for realizing riveted joint to riveted material 9.Certainly, this structure is just preferably a kind of, as long as the structure that can realize riveted all should be worked as belong to protection scope of the present invention, does not repeat herein.In addition, in the present invention " on ", D score do not limit practical structures of the present invention, the bearing change carried out based on this structure all belongs to protection scope of the present invention.
It should be noted that, the state when cope match-plate pattern 1 and lower bolster 2 have been in riveted is called matched moulds state; Be separated from each other when cope match-plate pattern 1 and lower bolster 2 are in and general state are not called to the state that riveted material 9 applies active force.
Wherein, patrix drift 3 is fixed in cope match-plate pattern 1, the bottom of patrix drift 3, namely forms the upper riveted face 5 of level near one end of the lower surface of cope match-plate pattern 1, and its center defines a upper riveted projection 6 downwards.Specifically, riveted projection 6 comprises vertical side and the bottom surface of level, and when acting on to prevent the protruding 6 pairs of riveted materials 9 of upper riveted, the local compression of riveted material 9 is excessively thin, the position connected in side and bottom surface preferably adopts round-corner transition.
Counterdie drift 4 is fixed in lower bolster 2, the top of counterdie drift 4, namely the lower riveted face 7 of level is formed near one end of the upper surface of lower bolster 2, its center forms a lower riveted projection 8 downwards, specifically, lower riveted projection 8 comprises vertical side and the end face of level, and when acting on to prevent the protruding 8 pairs of riveted materials 9 of lower riveted, the local compression of riveted material 9 is excessively thin, the position connected in side and top preferably adopts round-corner transition.
By on address composition graphs 1 to Fig. 4, we have understood the basic structure exempting from punching riveting die of the present invention, in fact, from relative both direction, active force is applied to riveted material 9 with counterdie drift 4 by patrix drift 3 in staking operation, that is, counterdie drift 4 pairs of riveted materials 9 apply active force upwards, and patrix drift 3 pairs of riveted materials 9 apply downward active force, make riveted material 9 that deformation occur, be in fact by riveted material 9 local " embedding " another riveted material 9, thus realize reliable riveted.
In order to by 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.It should be noted that, upper riveted face 5 is preferably identical with the shape in lower riveted face 7, and upper riveted projection 6 is also preferably identical with the shape of lower riveted projection 8.
In order to realize matched moulds state, as a kind of preferred version, patrix drift 3 is fixed in cope match-plate pattern 1 and both relative sliding can not occur, and counterdie drift 4 is fixed in lower bolster 2 and both can slide up and down relatively.
So, the detailed process of staking operation is as follows: as shown in Figure 2, riveted material 9 is placed and locator lower bolster 2 on, cope match-plate pattern 1 drives patrix drift 3 close to riveted material 9 together, when cope match-plate pattern 1 touches riveted material 9, namely applies active force to riveted material 9 and lower bolster 2, lower bolster 2 moves downward, until arrive matched moulds state, the state namely shown in Fig. 1, completes staking operation.A baffle plate is set below lower bolster 2, the position of lower bolster 2 is limited; Elastomeric element can also be set between lower bolster 2 and baffle plate, can automatically reset with lower bolster 2 under making general state, thus play the effect of protection counterdie drift 3.In whole staking operation, riveted material 9 can not slide, and can realize riveted joint exactly.
When riveting die is in matched moulds state, namely shown in Fig. 1 during state, the bottom of upper riveted projection 6, is namely no more than the lower surface of cope match-plate pattern 1 near one end of the lower surface of cope match-plate pattern 1; The top of lower riveted projection 8, namely exceeds the upper surface of lower bolster 2 near one end of the upper surface of lower bolster 2; Meanwhile, the upper surface in lower riveted face 7 also can exceed the upper surface of lower bolster 2, contributes to making riveted tightr.
In order to riveted material 9 is more reliably riveted together, as a kind of preferred version, when being in matched moulds state, the distance that lower riveted projection 8 exceeds lower bolster 2 upper surface is greater than the thick t of material of riveted material 9, and upper riveted face 5 is less than the thick t of material of riveted material 9 apart from the distance of the lower surface of cope match-plate pattern 1.
As a kind of preferred version, the gap between the edge in upper riveted face 5 and the edge in lower riveted face 7, namely monolateral gap P is 60% of the thick t of material of riveted material 9, that is: P=60%*t, and P=(d2-d1)/2.Once expect that thick t determines, then monolateral gap P also just determines thereupon, and that is, expect thick riveted material 9 for difference, the mould adopted is not identical.In the present invention, patrix drift 3 can take out from cope match-plate pattern 1, and counterdie drift 4 can take out from lower bolster 2, the riveted material 9 that riveted difference material is thick, only needs to replace with stamping head 3 and counterdie drift 4, effectively improves the versatility of mould.
Above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
