Description
Technical field
The utility model relates to handware stamping areas, and in particular to a kind of metal stamping die formed punch.
Background technique
Stamping die is that material (metal or nonmetallic) is processed into part (or semi-finished product) in Cold Press Working
A kind of special process equipment, referred to as cold punching die (being commonly called as cold-punching mould).Punching press is at room temperature, using being mounted on press machine
On mold to material apply pressure, make its generate separation or plastic deformation, thus obtain needed for part a kind of pressure processing
Method.
It is in the majority with handware stamping die in stamping die, it, can by punching press since metal has good ductility
It is set to generate plastic deformation, also because metal has ductility, in punching press separation, the metal that not can avoid incision generates modeling
Property deformation, to form incomplete notch.Generally punching mouth is arranged in lower die in existing hardware plate stamping mold, in upper mold
It is set to the punching matched punching block of mouth, separates hardware plate stamping by the two cooperation, this impact style is due to passing through
The pressure of punching block separates corresponding hardware plate, and the incision of hardware plate easily deforms, and causes on notch
Portion is arc-shaped after being pressurized.Therefore, we are badly in need of one kind and are capable of providing more smooth, reduce rushing of impacting of metal ductility
Head.
Utility model content
The main purpose of the utility model is to provide a kind of metal stamping die formed punch, it can efficiently solve background skill
The problem of in the presence of art.
To achieve the above object, the utility model proposes a kind of metal stamping die formed punch, including matrix is described
Matrix is in an inverted cone, and described matrix one end is provided with pressing part, and the pressing part is back taper, the pressing part and matrix
One end be flexibly connected so that the pressing part can be dismantled from the matrix, the pressing part and matrix
The size and shape of one end face of connection is adapted with the size and shape for the end face that the matrix is connect with pressing part, with
So that the outer surface of the pressing part and the smooth outer surface transition of matrix.
Preferably, the pressing part end is provided with several tips for aperture, the cross section of the tip
For triangular shape.
Preferably, the top of the tip is provided with cutter in the end face outside for starting extreme direction.
Preferably, the pressing part vertical projection is annular in shape.
Preferably, the middle position of the pressing part is provided with capaciting material groove.
The beneficial effects of the utility model are: the utility model is in an inverted cone by the way that matrix and pressing part are arranged, and rush
Splenium and matrix are detachably connected, and pressing part is separated from each other pressing part and matrix after giving the aperture of hardware plate stamping,
Matrix and pressing part can be detached from from the incision of hardware plate well, so that the notch after separating punching press is extremely smooth, essence
Degree is high.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, the structure that can also be shown according to these attached drawings obtains other attached drawings.
Fig. 1 is a kind of metal stamping die punch structure schematic diagram provided by the embodiment of the utility model.
Drawing reference numeral explanation:
| Label | Title | Label | Title |
| 1 | Matrix | 2 | Pressing part |
| 3 | Tip | 4 | Cutter |
| 5 | Holding tank |
The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute in the utility model embodiment
It is only used for explaining in relative positional relationship, the motion conditions etc. under a certain particular pose (as shown in the picture) between each component, such as
When the fruit particular pose changes, then directionality instruction also correspondingly changes correspondingly.
In addition, the description for being related to " first ", " second " etc. in the present invention is used for description purposes only, and cannot understand
For its relative importance of indication or suggestion or implicitly indicate the quantity of indicated technical characteristic.Define as a result, " first ",
The feature of " second " can explicitly or implicitly include at least one of the features.In addition, the technical side between each embodiment
