Specific embodiment party formula
In order to make the technical staff of this area understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
As Figure 1-3, before a kind of automobile that the utility model embodiment provides, the drawing die of longeron, comprises die 02, and the bottom of die 02 is provided with elastic material mechanism 01, one end of elastic material mechanism 01 is telescopic end, and the end face of this telescopic end crimps along mould punching direction with plate 05. Namely one end end face of elastic material mechanism 01 can crimp with plate 05 phase, and moves along the punching press direction of mould. Drawing process stretches in the bottom profile of die 02 outside starting the telescopic end end face of front elastic material mechanism 01, die 02 is driven by slide block on lathe, in upper slide block down process, first the telescopic end of elastic material mechanism 01 contacts with plate 05, and plate 05 is pressed on punch 04, die 02 continues descending, until the telescopic end end face of elastic material mechanism 01 is concordant with the bottom profile of die 02, now mould closes, and completes the drawing of plate 05. Afterwards, die 02 moves up under the drive of upper slide block, and die 02 released by workpiece by elastic material mechanism 01. Punch and matrix described herein is general reference, and namely this punch 04 can comprise the parts such as punch insert, lower die holder, and die 02 can also comprise die insert, upper die holder etc., and corresponding elastic material mechanism 01 can be fixed on die holder.
The drawing die that the utility model provides is in drawing process, first the telescopic end of elastic material mechanism 01 contacts with plate 05, and plate 05 is pressed on punch 04, before making formation, the plate 05 of longeron bottom surface produces predeformation, thus reduce the impact that it is produced by both sides plate distortion, decrease workpiece wrinkling, and drawing complete after under the promotion of elastic material mechanism 01 workpiece easily take out.
As shown in Figure 2, elastic material mechanism 01 comprises holder 11, telescopic drive element 13 and material pressing core 12, and holder 11 is fixed on die 02, and the end face of material pressing core 12 crimps along mould punching direction with plate 05. The end surface shape of material pressing core 12 can set according to the shape of product, to obtain better predeformation effect. In addition, holder 11 and die 02 can be integral structure, namely telescopic drive element 13 is directly fixed on die 02, installation process can be simplified like this, but owing to the connection form of telescopic drive element 13 is not fixed, this kind of form is unfavorable for again the processing of die 02, therefore preferably adopts former form in the present embodiment.
Further, material pressing core 12 being provided with guiding hole, the center line in guiding hole extends along mould punching direction, and one end of telescopic drive element 13 is connected through described guiding hole with described material pressing core 12. The plate 05 that can prevent material pressing core 12 from rocking and cause like this is collected together, it is to increase structure performance.
Further, it is slidably matched between above-mentioned material pressing core 12 and die 02, specifically, one can be arranged in the bottom profile of die 02 and cross hole, the center line crossing hole extends along mould punching direction, and the outer surface of material pressing core 12, with crossing hole laminating, can achieve the above object equally. Certainly, it is also possible to while arranging guiding hole on material pressing core 12, make to be slidably matched between material pressing core 12 and die 02, to obtain better effect.
Preferably, above-mentioned telescopic drive element 13 is nitrogen spring, and nitrogen spring possesses that volume is little, elastic force is big, stable working, it may also be useful to the advantages such as life-span length, it is possible to simplify the Design and manufacture of mould, facilitate mould install and adjust, extend the mold use life-span.
Preferably, above-mentioned elastic material mechanism 01 is at least two, has prepared separation between each described elastic material mechanism 01. As shown in Figure 3, Liang Ge elastic material mechanism 01 lays respectively at the two ends of plate 05, and like this in punching course, plate 05 two ends are held down mid portion and produce certain predeformation, thus reduce the impact that it is produced by the distortion of both sides plates, it is to increase forming quality. If not taking this kind of mode and all being pushed down by bottom plate 05, then plate 05 cannot flow and subtract thin, it is easy to causes shaping insufficient, produces the quality problems such as resilience, distortion.
Only describe some one exemplary embodiment of the present utility model by the mode of explanation above, undoubtedly, for the those of ordinary skill of this area, when not deviateing spirit and scope of the present utility model, it is possible to by various different mode, described embodiment is revised. Therefore, above-mentioned accompanying drawing and description are being explanation property in essence, it should not be interpreted as the restriction to the utility model claims.
