Abstract
The invention provides a stamping die. The stamping die comprises a punch fixing plate, an unloading rear plate, an unloading plate and a lower die plate, the unloading rear plate is located one the lower side of the punch fixing plate, the unloading plate is fixed on the lower side of the unloading rear plate, the lower die plate is located on the lower side of the unloading plate, a surface of one side of the unloading plate, which is opposite to the lower die plate, is provided with a plurality of sections of difference grooves in a concave mode, accordingly, the contact area between the unloading plate and the lower die plate can be reduced, and noises caused by clashing between the unloading plate and the lower die plate during the working process of the stamping die can be reduced.
Description
Technical field
The present invention relates to a kind of diel, relate 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 mould design and manufacturing.The height of mould design and manufacturing technology level is one of important symbol of weighing a national product manufacture level height, is determining the development ability of quality, benefit and the new product of product to a great extent.The instrument that be used for drawing of diel for being processed by metal and other rigid materials, it includes punch fixing plate, discharging backboard, stripper, lower bolster or the like structure.In the course of the work, can clash between each plate, the noise that behind bump, produces 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.
Summary of the invention
The object of the present invention is to provide a kind of diel that reduces noise.
For realizing the foregoing invention purpose; The invention 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 said stripper and lower bolster are relative is concaved with plurality of sections difference groove.
As further improvement of the present invention, said section poor groove along continuous straight runs runs through said stripper.
As further improvement of the present invention, said diel also comprises the interior limited post that is fixed on the said punch fixing plate, and said interior limited post exceeds the side surface of said punch fixing plate near said discharging backboard towards the projection of said discharging backboard direction.
As further improvement of the present invention, said interior limited post is fixed on the center position of said punch fixing plate.
As further improvement of the present invention, said 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 invention has the beneficial effects as follows: diel of the present invention is through being provided with plurality of sections difference groove at a said 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 diel of the present invention discharging version in the course of the work and the lower bolster.
Description of drawings
Fig. 1 is the structural representation of diel of the present invention;
Fig. 2 is the upward view of stripper among Fig. 1.
The specific embodiment
Below will combine each embodiment shown in the drawings to describe the present invention.But these embodiments do not limit the present invention, 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 protection scope of the present invention.
Please referring to figs. 1 through shown in Figure 2 for a preferred embodiments of diel 100 of the present invention.Said 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 patrixes.Said lower bolster 6, lower bolster 7 and die shoe 8 are fixing successively and form counterdie.
Said stripper 5 is concaved with plurality of sections difference groove 51 with lower bolster 6 relative side surfaces; Can reduce the contact area between said discharging version 5 and the lower bolster 6 thus, and then reduce the noise that produces because of bump between diel 100 discharging versions in the course of the work 5 of the present invention and the lower bolster 6.Said section poor groove 51 degree of depth are 0.2 millimeter, and said section poor groove 51 along continuous straight runs run through said stripper 5.
In addition, said diel 100 also comprises the interior limited post 31 that is fixed on the said punch fixing plate 3.Limited post 31 exceeds the side surface of said punch fixing plate 3 near said discharging backboard 4 towards said discharging backboard 4 direction projections in said; Thereby can avoid the face contact between said punch fixing plate 3 and the discharging backboard 4; And the local way of contact of limited post 31 in the present invention 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, said diel 100 can be provided with a plurality of said interior limited posts 31, and limited post 31 in said evenly is fixed on the said punch fixing plate 3.
Get by above; The present invention is through being provided with plurality of sections difference groove 51 at said stripper 5 with 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 diel 100 discharging versions in the course of the work 5 of the present invention and the lower bolster 6; In addition; Through the interior limited post 31 that exceeds punch fixing plate 3 towards the 4 direction projections of discharging backboard is set on said punch fixing plate 3; The local way of contact of limited post 31 and discharging backboard 4 in promptly 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; Though 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, and those skilled in the art should make specification as a whole; Technical scheme in each embodiment also can form other embodiments that it will be appreciated by those skilled in the art that through appropriate combination.
The listed a series of detailed description of preceding text only is specifying to feasibility embodiment of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent embodiment or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
