Detailed description of the invention
For the technical scheme making to present invention solves the technical problem that, adopting and the technique effect reached clearly, below in conjunction with accompanying drawing, the technical scheme of embodiment of the present invention is described in further detail, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those skilled in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
In describing the invention; it will be appreciated that; term " orientation or the position relationship of the instruction such as " center ", " longitudinal direction ", " transverse direction ", "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", " outward " be based on orientation shown in the drawings or position relationship; be for only for ease of the description present invention and simplifying and describe; rather than instruction or imply indication device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that limiting the scope of the invention.
Present embodiment proposes the mould of a kind of novel backboard self-clinching standoff, as shown in Figure 1, the mould of this backboard self-clinching standoff includes upper die component and lower mold assemblies, and wherein, upper die component includes the mounting plate 1, upper bolster 2, upper padding plate 3 and the cope match-plate pattern 4 that removably connect successively from top to bottom.Lower mold assemblies includes the lower bolster 5, lower bolster 6, die shoe 7 and the bottom plate 8 that removably connect successively from top to bottom.Wherein, the setting of mounting plate 1 and bottom plate 8 can easy disassembly, more mold exchange.The setting of upper padding plate 3 and lower bolster 6 is prevented from that impulsive force is excessive and then damage upper bolster 2 and die shoe 7, plays certain cushioning effect.
In the present embodiment, lower bolster 5 is provided with three stud bolt holes 51, the setting of three stud bolt holes 51 makes product when self-clinching standoff, stud 9 be positioned, cope match-plate pattern 4 is provided with three rivet punches 41 matched with stud bolt hole 51, when upper die component and lower mold assemblies Guan Bi, stud 9 can be pressed in product (backboard 10 as shown in Figure 1) by rivet punch 41.The setting of multiple stud bolt holes 51 can realize multiple stud 9 that simultaneously presses on backboard 10, and production efficiency is further enhanced.So, the mould of the application backboard self-clinching standoff disposable can complete pressing of product upper stud 9, simple in construction, production efficiency is high, meanwhile, realize being accurately positioned by stud bolt hole 51 in self-clinching standoff process, be prevented effectively from stud 9 and press inclination, the phenomenon that product deforms, finished product rate is high.
In the present embodiment, the bottom of three stud bolt holes 51 is provided with in stud head part 52, it is possible to contacts with stud 9 in product self-clinching standoff process, is pressed in product by stud 9 smoothly.
Additionally, lower mold assemblies is provided with the Lifting Device contacting product, the Lifting Device of present embodiment has two groups, two groups of Lifting Device are symmetricly set on the both sides of lower mold assemblies, often group Lifting Device includes the jigger pin 11 being arranged on lower bolster 5 and the first support spring 12 being arranged on bottom jigger pin 11, the first bottom surface conflict die shoe 7 supporting spring 12, the top of jigger pin 11 up contacts product.
In the present embodiment, elastic positioning device it is provided with between upper die component and lower mold assemblies.Elastic positioning device includes alignment pin 13 and corresponding hole, location (not shown), hole, location is arranged on the bottom of lower bolster 5, alignment pin 13 traverse cope match-plate pattern 4, the bottom of alignment pin 13 is provided with the second support spring 14, the second end face conflict upper bolster 2 supporting spring 14, the top of alignment pin 13 down extrudes cope match-plate pattern 4.Location is provided with buffer spring bottom hole.Under buffer spring nature extended configuration, its bottom is that alignment pin 13 stretches out 2nd/to three/2nd of face length to the length between outer end of hole face, location, enables alignment pin 13 to shrink generation elastic force when inserting hole, location.It is provided with stage clip 15 between cope match-plate pattern 4 and upper bolster 2, the cushioning effect in work process can be increased, improve punching press stability.
In use, upper die component moves downward, and alignment pin 13 inserts hole, location, upper die component continues to move downward, the upper surface of alignment pin 13 and buffer spring bottom contact, and buffer spring and second supports spring 14 and all shrinks generation elastic force, and the common motion for cope match-plate pattern 4 brings buffering.Second supports spring 14 contraction makes the power of alignment pin 13 bottom squeeze cope match-plate pattern 4 be gradually reduced, namely the support force of cope match-plate pattern 4 is gradually reduced by the second support spring 14, the stage clip 15 and second of cope match-plate pattern 4 supports spring 14 common support cope match-plate pattern 4, when cope match-plate pattern 4 support force is gradually reduced by the second support spring 14, the first of lower bolster 5 supports spring 12 pressure and becomes larger and shrink generation elastic force, brings buffering when contacting lower bolster 5 for cope match-plate pattern 4.It is more fast that upper die component moves downward speed, and the first support spring 12 of lower bolster 5 gives the cushioning effect that cope match-plate pattern 4 brings more notable.Before cope match-plate pattern 4 contacts lower bolster 5, buffer spring, the second support spring 14 coordinate the double cushioning effect of generation.When cope match-plate pattern 4 contacts lower bolster 5, buffer spring, first support that spring 12, second supports spring 14, the cooperation of stage clip 15 produces cushioning effect jointly.Second supports spring 14 progressive formation to cope match-plate pattern 4 support force, improves punching press stability and yield rate, reduces die wear, increase the service life.
Guiding mechanism it is provided with between upper die component and lower mold assemblies.Guiding mechanism includes the guide pillar being arranged on cope match-plate pattern 4 and the gathering sill being arranged on lower bolster 5, and guide pillar is provided with damping spring, and gathering sill and guide pillar match.By the setting of guiding mechanism, it is possible in the course of processing, mould is accurately positioned, improve machining accuracy.
The know-why of the present invention is described above in association with detailed description of the invention.These descriptions are intended merely to explanation principles of the invention, and can not be construed to limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art need not pay creative work can associate other detailed description of the invention of the present invention, and these modes fall within protection scope of the present invention.
