The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
Referring to Fig. 1 and Fig. 2, the 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 used for fixing patrix drift 3, and lower bolster 2 is used for fixing counterdie drift 4.Seeing that mostly riveted construction is circle, the patrix drift 3 among the present invention all is preferably rotary structure with counterdie drift 4, perhaps at least at the part formation rotary structure that is being used for riveted material 9 is realized riveted joint.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 scope of the present invention, does not give unnecessary details here.In addition, among the present invention " on ", D score does not limit practical structures of the present invention, is that the bearing change that carry out on the basis all belongs to protection scope of the present invention with this structure.
Need to prove that the state when cope match-plate pattern 1 and lower bolster 2 are in the completion riveted 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, and the bottom of patrix drift 3 promptly forms the last riveted face 5 of level near an end of the lower surface of cope match-plate pattern 1, wherein formed one under the mind-set and gone up riveted protruding 6.Particularly, riveted protruding 6 comprises vertical side and the bottom surface of level, does the time spent and the part of riveted material 9 is pushed thin in order to prevent 6 pairs of riveted materials 9 of riveted convexity, and round-corner transition is preferably adopted in the position that joins in side and bottom surface.
Counterdie drift 4 is fixed in the lower bolster 2; The top of counterdie drift 4 promptly forms the following riveted face 7 of level near an end of the upper surface of lower bolster 2, wherein form a following riveted protruding 8 under the mind-set; Particularly; Following riveted protruding 8 comprises vertical side and the end face of level, for prevent down the protruding 8 pairs of riveted materials 9 of riveted do the time spent part of riveted material 9 was pushed thin, in the side with push up the position that joins and preferably adopt round-corner transition.
Through on address and combine Fig. 1 to Fig. 4; We have understood the basic structure of exempting from the punching riveting die of the present invention, in fact, in the riveted operation, are from relative both direction riveted material 9 to be applied active force through patrix drift 3 and counterdie drift 4; 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 take place; Come down 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 ", like Fig. 3 and shown in Figure 4, last riveted face 5 is greater than following riveted face 7, and promptly d2 is greater than d1, and the horizontal cross-section of going up riveted protruding 6 is greater than the horizontal cross-section of riveted protruding 8 down.Need to prove that last riveted face 5 is preferably identical with the shape of following riveted face 7, last riveted protruding 6 is also preferably identical with the shape of following riveted protruding 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 slip can not take place 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 following: as shown in Figure 2, on 9 placements of riveted material and locator lower bolster 2; Cope match-plate pattern 1 drive patrix drift 3 together to riveted material 9 near, when cope match-plate pattern 1 touches riveted material 9, promptly riveted material 9 and lower bolster 2 are applied active force; 2 of lower bolsters move downward; Until arriving the matched moulds state, state promptly shown in Figure 1 is accomplished 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,, thereby play the effect of protecting counterdie drift 3 so that lower bolster 2 can automatically reset under the general state.In the whole riveted operation, riveted material 9 can not slide, and can realize riveted joint exactly.
When riveting die is in the matched moulds state, during state promptly shown in Figure 1, the bottom of last riveted protruding 6 promptly 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 following riveted protruding 8 promptly exceeds the upper surface of lower bolster 2 near an end of the upper surface of lower bolster 2; Simultaneously, the upper surface of following 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, following riveted protruding 8 exceeds the material thick t of the distance of lower bolster 2 upper surfaces greater than riveted material 9, and last 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 last riveted face 5 and following riveted face 7,60% of the thick t of material that promptly monolateral gap P is a riveted material 9, that is: P=60%*t, and P=(d2-d1)/2.Confirmed that in case expect thick t then monolateral gap P has also just confirmed thereupon, that is to say that to the thick riveted material 9 of difference material, the mould that is adopted is inequality.Among 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, and the thick riveted material 9 of the different material of riveted only needs to change patrix drift 3 and gets final product with counterdie drift 4, has effectively improved the versatility of mould.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
