The specific embodiment
Core of the present utility model is to provide a kind of diel of Auto-body Panel, and this diel can realize the buffering between patrix and work limited block, reduces the cost of diel simultaneously.
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further detailed.
As Figure 1-4, the utility model embodiment provides a kind of diel of Auto-body Panel, this diel comprises upper bolster 11, die shoe 12 and is arranged at work limited block 13, stroke limit piece 14, guide plate 15, guide pillar 16 and the elastic buffer piece 17 on die shoe 12, wherein:
Work limited block 13 can be arranged on die shoe 12 by threaded fastener, descending and with work limited block 13 while contacting under the effect of upper bolster 11 at forcing press, work limited block 13 is by the continuation campaign of restriction upper bolster 11, and then the work location of realizing upper bolster 11;
Stroke limit piece 14 is movable part, and in carrying out the process of punching operation, stroke limit piece 14 is placed in the groove of die shoe 12, so as not to upper bolster 11 when descending and upper bolster 11 interfere; Diel is when storage configuration, and stroke limit piece 14 and work limited block 13 cooperatings, be positioned over stroke limit piece 14 on work limited block 13, utilizes stroke limit piece 14 to support upper bolster 11, prevents that the flexible member in upper bolster 11 is impaired; Particularly, when stroke limit piece 14 is placed in the groove of die shoe 12, its upper level is at least than the low 15mm of upper level of work limited block 13, to avoid stroke limit piece 14 and upper bolster 11 to interfere;
Guide plate 15 and guide pillar 16 all provide guiding for the relative motion between upper bolster 11 and die shoe 12;
Elastic buffer piece 17 is made by elastomeric material, it can be adhered on die shoe 12, elastic buffer piece 17 does not occur before deformation, its end face, along the minimum range between the corresponding position of the working face of pressing direction and upper bolster 11, is less than the end face of work limited block 13 along the minimum range between the corresponding position of the working face of pressing direction and upper bolster 11; The height of elastic buffer piece 17 is: the installed position of elastic buffer piece 17, shut height between upper bolster 11 and die shoe 12 and the amount of elastic deformation sum of elastic buffer piece 17, wherein, the amount of elastic deformation of elastic buffer piece 17 can calculate according to weight of the elastic deformation coefficient of the size of elastic buffer piece 17, its manufactured materials, upper bolster 11 etc.
After so arranging, when the upper bolster 11 of diel is descending, first contact with elastic buffer piece 17, upper bolster 11 continues descending, and elastic buffer piece 17 compressive deformations are realized buffering.Along with the deflection of elastic buffer piece 17 constantly increases, upper bolster 11 will contact with work limited block 13, and then arrival closure state position.
Known by foregoing description, than the content of introducing in background technology, the diel that the utility model embodiment provides has increased elastic buffer piece 17, by the deformation realization buffering of this elastic buffer piece 17, the active force between upper bolster 11 and work limited block 13 is reduced; And than nitrogen spring, above-mentioned elastic buffer piece 17 is made by lower-cost elastomeric material, the cost of whole diel is lower.In addition, adopt after elastic buffer piece 17, noise during diel operation is less.
Further, in technical scheme, the upper surface of elastic buffer piece 17 is the plane perpendicular to pressing direction, and on upper bolster 11, the stamping surface that covers elastic buffer piece 17 along pressing direction is the plane perpendicular to pressing direction.What this structure made elastic buffer piece 17 is subject to force direction only on pressing direction, and its distortion is also just only embodied on pressing direction, and then after preventing that being out of shape from appearring in resilient snubber 17 in the other direction, the poor phenomenon of shock-absorbing capacity of elastic buffer piece 17.
In order to obtain the elastic buffer piece 17 that a kind of installation strength is higher, can on elastic buffer piece 17, offer shoulder hole, elastic buffer piece 17 is fixed on die shoe 12 by the securing member penetrating in shoulder hole.In addition, the top of above-mentioned shoulder hole makes the generation space, middle part of elastic buffer piece 17, and after elastic buffer piece 17 is stressed, deformation more easily occurs elastic buffer piece 17, and then reaches better buffering effect.
If elastic buffer piece 17 can not expectational factor cause structural failure because collision waits other, during production, may occur that the part block structure of damaging collapses the problem in diel, easily damages operating personnel.In order to alleviate this problem, the diel that the utility model embodiment provides also comprises the protective cover 18 being arranged on die shoe 12, elastic buffer piece 17 is positioned at protective cover 18 inside, and there is predeterminable range between the inwall of the sidewall of elastic buffer piece 17 and protective cover 18, the top of elastic buffer piece 17, with respect to the height of the bottom of die shoe 12, is greater than the top of protective cover 18 with respect to the height of the bottom of die shoe 12.Visible, this protective cover 18 neither can affect the distortion of elastic buffer piece 17, can also prevent from, because can not expectational factor causing, operating personnel are produced to injury.
Particularly, the protective cover 18 in a upper scheme can be barrel structure always, and its two ends are hatch frame.In another kind of embodiment, protective cover 18 can comprise base plate and the side plate fixing with base plate, has installing hole on base plate, can be through fixing with die shoe 12 after shoulder hole and installing hole for the securing member of elastic buffer piece 17 is installed.Under this structure, the installation of elastic buffer piece 17 is more convenient.
When avoiding as much as possible upper bolster 11 descending, before contacting with work limited block 13, first occur with the phenomenon of protective cover 18 effects, in the utility model embodiment, the height of protective cover 18 is less than upper bolster 11 and die shoe 12 in the shut height at elastic buffer piece 17 places, and difference is between the two 5mm-10mm.
Further, elastic buffer piece 17 is at least two, and at least two elastic buffer pieces 17 distribute along the working face of die shoe 12, with this, improve the buffering effect of whole diel.Based on die shoe 12, be roughly rectangular configuration, therefore elastic buffer piece 17 can be set to four groups, four groups of elastic buffer pieces 17 are distributed in respectively the place, four angles of die shoe 12.
The shape of aforesaid elastic buffer piece 17 and protective cover 18 can be elected triangle, rectangle etc. as according to actual conditions, in order to obtain a kind of distortion elastic buffer piece 17 comparatively uniformly, elastic buffer piece 17 can be set to cylindrical piece; For the ease of processing, protective cover 18 can be set to cylindrical structure.In addition, the manufactured materials of elastic buffer piece 17 can be set to polyurethane, with this, obtains a kind of elastic buffer piece 17 with polyurethane column structure, makes the shock-absorbing capacity of elastic buffer piece 17 better.
Only by the mode of explanation, some one exemplary embodiment of the present utility model has been described above, undoubtedly, for those of ordinary skill in the art, in the situation that not departing from spirit and scope of the present utility model, can to described embodiment, revise by various mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claim protection domain.
