The anti-stamping jig for running bits so as to more the value in industry.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of for the anti-stamping jig for running bits.
For achieving the above object, this utility model is adopted the following technical scheme that：
It is a kind of to run the stamping jig considered to be worth doing for anti-, including lower template, in the lower template, offer several lower nibs, institute
State lower nib to be made up of lower die cutter mouth and material-dropping hole, the lower die cutter mouth is with material-dropping hole in lower upper integral type arrangement, the lower mould
Diameter of the diameter of the edge of a knife less than material-dropping hole, the lower die cutter mouth is provided with changeover portion between being connected with material-dropping hole, described
Changeover portion is for being in tilted layout, and changeover portion and lower die cutter mouth are formed in one arrangement.
Further, the described stamping jig for anti-race bits, wherein, the range of tilt angles of the changeover portion exists
30 ° to 45 °.
Further, the described stamping jig for anti-race bits, wherein, the angle of inclination of the changeover portion is 45 °.
Further, the described stamping jig for anti-race bits, wherein, the length range of the changeover portion is in 2 millis
Rice is to 5 millimeters.
Again further, the described stamping jig for anti-race bits, wherein, the inclination of the changeover portion is to be polished into
Type.
By such scheme, this utility model at least has advantages below：
This utility model is by passing through to arrange inclined changeover portion between lower die cutter mouth and material-dropping hole, and passes through to limit
The angle for crossing section can preferably prevent scrap from running chaotically, and so as to be effectively protected product surface not damaged, improve the yield of product.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of description, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.

In order to be illustrated more clearly that the technical scheme of this utility model embodiment, below will be to using needed for embodiment
Accompanying drawing be briefly described, it will be appreciated that the following drawings illustrate only some embodiments of the present utility model, therefore should not be by
Regard the restriction to scope as, for those of ordinary skill in the art, on the premise of not paying creative work, may be used also
To obtain other related accompanying drawings according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
In order that those skilled in the art more fully understand this utility model scheme, below in conjunction with this utility model reality
Accompanying drawing in example is applied, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described reality
Apply the example only a part of embodiment of this utility model, rather than the embodiment of whole.And show described in accompanying drawing generally herein
The component of this utility model embodiment for going out can be arranged and be designed with a variety of configurations.Therefore, below in accompanying drawing
The detailed description of the embodiment of the present utility model of middle offer is not intended to limit claimed scope of the present utility model, and
It is to be merely representative of selected embodiment of the present utility model.Based on embodiment of the present utility model, those skilled in the art are not having
The every other embodiment obtained on the premise of making creative work, belongs to the scope of this utility model protection.
Embodiment
As shown in figure 1, it is a kind of for the anti-stamping jig for running bits, including lower template 1, if offering in the lower template 1
Dry lower nib, the lower nib are made up of lower die cutter mouth 2 and material-dropping hole 3, and the lower die cutter mouth 2 is in lower upper one with material-dropping hole 3
Body formula arranges that the diameter that 2 mouthfuls of the lower die cutter is less than the diameter of material-dropping hole 3, what the lower die cutter mouth 2 was connected with material-dropping hole 4
Between be provided with changeover portion 4, the changeover portion 4 is for being in tilted layout, and changeover portion 4 and lower die cutter mouth are formed in one arrangement, logical
Cross by arranging inclined changeover portion between lower die cutter mouth and material-dropping hole, and preferably can be prevented by the angle for limiting changeover portion
Only scrap is run chaotically, so as to be effectively protected product surface not damaged.
The range of tilt angles of changeover portion 4 described in this utility model is at 30 ° to 45 °, and the changeover portion 4 in use
Angle of inclination be 45 °, using 45 ° of angle of inclination, can by scrap bumping post as far as possible, prevent scrap follow mould knife reset
When, which is together taken away to the surface of product, so as to have influence on the surface of product.
The length range of changeover portion 4 described in this utility model at 2 millimeters to 5 millimeters, according to the inclination angle of above-mentioned employing
Degree, changes the length of its changeover portion 4 so as to can also possess the situation for preventing scrap from running chaotically while angle is changed.
According to above-mentioned angle of inclination again 45 degree when, it is 3 millimeters that the length of its changeover portion 4 is relatively short, and incline
When angle is 30 °, its length is 5 millimeters, ensures the situation that scrap is run chaotically by different length and angle.
For above-mentioned angle and the structure of length, the inclination of its changeover portion is polishing molding, can be made by polishing
Changeover portion reaches rational requirement, and so as to ensure when in use, in punching, its scrap for producing is not in what is run chaotically to product
Situation, its scrap are effectively suppressed, and so as to the protection that the surface for ensureing product also obtains, further improve product
Obtain yield.
This utility model is by passing through to arrange inclined changeover portion between lower die cutter mouth and material-dropping hole, and passes through to limit
The angle for crossing section can preferably prevent scrap from running chaotically, and so as to be effectively protected product surface not damaged, improve the yield of product.
The above is only preferred implementation of the present utility model, is not limited to this utility model, it is noted that
For those skilled in the art, on the premise of without departing from this utility model know-why, can also do
Go out some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
