Abstract
The utility model provides a stamping die. The stamping die comprises a pouch fixing plate, a material discharge back plate, a material discharging plate and a lower die plate, wherein the material discharging back plate is located below the material discharging back plate, the material discharging plate is fixed under the material discharging back plate, and the lower die plate is located under the material discharging plate. A plurality of level difference grooves are concavely formed in the surface, opposite to the lower die plate, of the material discharging plate, so that the contacting area of the material discharging plate and the lower die plate can be reduced, and therefore noise generated between the material discharging plate and the lower die plate in the working process of the stamping die due to impacts is lowered.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to the less diel of a kind of noise.
Background technology
Diel is the requisite technological equipment of punching production, is technology-intensive product.The quality of stamping parts, production efficiency and production cost etc. have direct relation with Design of Dies and manufacturing.The height of Design of Dies and manufacturing technology level is one of important symbol of weighing a national product manufacture level height, is determining to a great extent the development ability of quality, benefit and the new product of product.The be used for stamping instrument of diel for being made by metal and other rigid materials, it includes punch fixing plate, discharging backboard, stripper, lower bolster etc. structure.In the course of the work, can clash between each plate, the noise that produces behind bump not only has harm to staff's human body, but also causes environmental pollution.Particularly height diel, this kind noise problem is particularly serious.
Therefore, be necessary to provide a kind of improved diel to address the above problem.
The utility model content
The purpose of this utility model is to provide a kind of diel that reduces noise.
For realizing above-mentioned utility model purpose, the utility model provides a kind of diel, comprise punch fixing plate, be positioned at the punch fixing plate downside the discharging backboard, be fixed in the stripper of discharging backboard downside and the lower bolster that is positioned at the stripper downside, the side surface that described stripper is relative with lower bolster is concaved with some sections poor grooves.
As further improvement of the utility model, described section poor groove along continuous straight runs runs through described stripper.
As further improvement of the utility model, described diel also comprises the interior limited post that is fixed on the described punch fixing plate, and described interior limited post exceeds described punch fixing plate near a side surface of described discharging backboard towards the projection of described discharging backboard direction.
As further improvement of the utility model, described interior limited post is fixed on the center position of described punch fixing plate.
As further improvement of the utility model, described diel also comprises the upper padding plate that is positioned at the punch fixing plate upside, the upper bolster that is fixed on the upper padding plate upside, the die shoe that is fixed on the lower bolster of lower bolster downside and is fixed on the lower bolster downside.
The beneficial effects of the utility model are: the utility model diel is by arranging some sections poor grooves at a described stripper side surface relative with lower bolster, thereby can reduce the contact area between discharging version and the lower bolster, and then reduce the noise that produces because of bump between in the course of the work discharging version of the utility model diel and the lower bolster.
Description of drawings
Fig. 1 is the structural representation of the utility model diel;
Fig. 2 is the upward view of stripper among Fig. 1.
The specific embodiment
Below with reference to each embodiment shown in the drawings the utility model is described in detail.But these embodiments do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiments, method or the function all is included in the protection domain of the present utility model.
Please refer to Fig. 1 to a preferred embodiments that Figure 2 shows that the utility model diel 100.Described diel 100 comprises upper bolster 1 from top to bottom successively, be fixed on the upper padding plate 2 of upper bolster 1 downside, be fixed on the upper bolster 1 and be positioned at upper padding plate 2 downsides punch fixing plate 3, be positioned at punch fixing plate 3 downsides discharging backboard 4, be fixed on the upper bolster 1 and be positioned at discharging backboard 4 downsides stripper 5, be positioned at stripper 5 downsides lower bolster 6, be fixed on the lower bolster 7 of lower bolster 6 downsides and be fixed on lower bolster 7 downsides to support the die shoe 8 of lower bolster 6.Wherein said upper bolster 1, upper padding plate 2, punch fixing plate 3, discharging backboard 4 and stripper 5 form patrix.Described lower bolster 6, lower bolster 7 and die shoe 8 are fixed and the formation counterdie successively.
Described stripper 5 and lower bolster 6 relative side surfaces are concaved with some sections poor grooves 51, can reduce thus the contact area between described discharging version 5 and the lower bolster 6, and then reduce the noise that produces because of bump between the utility model diel 100 in the course of the work discharging versions 5 and the lower bolster 6.Described section poor groove 51 degree of depth are 0.2 millimeter, and described section poor groove 51 along continuous straight runs run through described stripper 5.
In addition, described diel 100 also comprises the interior limited post 31 that is fixed on the described punch fixing plate 3.Described interior limited post 31 exceeds described punch fixing plate 3 near a side surface of described discharging backboard 4 towards described discharging backboard 4 direction projections, thereby can avoid the face contact between described punch fixing plate 3 and the discharging backboard 4, and the local way of contact of limited post 31 in the utility model adopts, can avoid the large tracts of land contact between punch fixing plate 3 and the discharging backboard 4, thereby reduce the noise that both produce because of bump.Certainly, described diel 100 can be provided with a plurality of described interior limited posts 31, and described interior limited post 31 evenly is fixed on the described punch fixing plate 3.
Got by above, the utility model is by arranging some sections poor grooves 51 at described stripper 5 and lower bolster 6 relative side surfaces, thereby can reduce the contact area between discharging version 5 and the lower bolster 6, and then reduce the noise that produces because of bump between the utility model diel 100 in the course of the work discharging versions 5 and the lower bolster 6; In addition, by the interior limited post 31 that exceeds punch fixing plate 3 towards the 4 direction projections of discharging backboard is set at described punch fixing plate 3, the local way of contact of limited post 31 and discharging backboard 4 in namely adopting, can avoid the large tracts of land contact between punch fixing plate 3 and the discharging backboard 4, thereby reduce the noise that both produce because of bump.
Be to be understood that, although this specification is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technical scheme in each embodiment also can through appropriate combination, form other embodiments that it will be appreciated by those skilled in the art that.
Above listed a series of detailed description only is specifying for feasibility embodiment of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent embodiment or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.
