Abstract
The utility model discloses a kind of punch structure, including punch-pin, punch-pin is fixedly connected below upper die holder by punch retainer, the punch-pin is made of several section convex modules, elastic mechanism is provided between the convex module and convex module, one end of the elastic mechanism is flexibly connected with the middle position of a convex module, the other end is flexibly connected with the middle position of another convex module.The utility model is avoided that since punch-pin unstability or impulse force are excessive and lead to Punch rupture.
Description
Technical field
The utility model relates to dieparts technical fields, more particularly to a kind of punch structure.
Background technique
Square hole is rushed on more parts such as locking rocker arm, release rocker arm, screw rod in certain products or slot is punched on plate
Mouthful, and hole and notch size is smaller, shape is also had nothing in common with each other.Usually when designing the punching die of this type shape, generally
Using integral-typed punch design structure, i.e. die shank, backing plate, fixed plate, punch-pin is integrated.Integral-typed punch is in blanking process
In, the problem of being easy to appear: if one, in punching, upper die holder is subjected to displacement, it is easy to because punch-pin unstability leads to Punch rupture；
Two, during punch-pin downlink, if downstream rate is too fast, Punch rupture is easy to cause because impulse force is excessive.
Utility model content
The main purpose of the utility model is to provide a kind of punch structure, to avoid due to punch-pin unstability or impulse force it is excessive
And lead to Punch rupture.
To achieve the above object, the utility model proposes a kind of punch structure, including punch-pin, punch-pin fixed by punch-pin
Plate is fixedly connected below upper die holder, and the punch-pin is made of several section convex modules, between the convex module and convex module
Be provided with elastic mechanism, one end of the elastic mechanism is flexibly connected with the middle position of a convex module, the other end with it is another
The middle position of convex module is flexibly connected.
Preferably, the length of the elastic mechanism is set as 5-10mm.
Preferably, the elastic mechanism is elastic rubber or spring.
Preferably, backing plate is provided between the punch-pin and upper die holder.
The beneficial effects of the utility model are: since punch-pin is made of several section convex modules, and convex module and convex module it
Between be provided with elastic mechanism, if due to the flecition of elastic mechanism, enabling punch-pin if upper die holder is subjected to displacement in punching
Bending is slightly done, so that punch-pin unstability be avoided to lead to Punch rupture；If impulse force is excessive, elastic mechanism be can play a buffer role in,
It avoids and is easy to cause Punch rupture because impulse force is excessive.
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 structural schematic diagram of punch structure of the utility model.
Drawing reference numeral explanation:
| Label | Title | Label | Title |
| 1 | Punch-pin | 11 | Convex module |
| 2 | Punch retainer | 3 | Elastic mechanism |
| 4 | Backing plate |
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
Case can be combined with each other, but must be based on can be realized by those of ordinary skill in the art, when the combination of technical solution
Conflicting or cannot achieve when occur will be understood that the combination of this technical solution is not present, also not in the requires of the utility model
Protection scope within.
In the utility model embodiment, referring to Fig.1, the punch structure, including punch-pin 1, punch-pin 1 pass through punch retainer
2 are fixedly connected below upper die holder, and backing plate 4 is provided between the punch-pin 1 and upper die holder.The punch-pin 1 is by several sections
Convex module 11 forms, and elastic mechanism 3 is provided between the convex module 11 and convex module 11, and the elastic mechanism 3 is bullet
Property rubber or spring.One end of the elastic mechanism 3 is flexibly connected with the middle position of a convex module 11, the other end and another
The middle position of one convex module 11 is flexibly connected.Under preferable case, the top and bottom of the elastic mechanism 3 are respectively and up and down
11 snapping of convex module at both ends, so that the elastic mechanism 3 is removably attachable to convex module 11, elastic mechanism 3 is rushed in realization
With being detachably connected for convex module 11, convenient for the replacement of elastic mechanism 3 and convex module 11.
The present embodiment is provided between convex module 11 and convex module 11 since punch-pin 1 is made of several section convex modules 11
Elastic mechanism 3, if if upper die holder is subjected to displacement in punching, due to the flecition of elastic mechanism 3, enable punch-pin 1 slightly
Bending is done, to avoid punch-pin unstability that punch-pin 1 is caused to be broken；If impulse force is excessive, elastic mechanism 3 be can play a buffer role in, and be kept away
Exempt to be easy to cause punch-pin 1 to be broken because impulse force is excessive.
In the present embodiment, the length of the elastic mechanism 3 is set as 5-10mm, convex module when avoiding 1 downlink of punch-pin
It is easy to generate positional shift because gap is too big between 11 and convex module 11, to influence punching press effect.The foregoing is merely this
The preferred embodiment of utility model, therefore it does not limit the scope of the patent of the utility model, all in the practical of the utility model
Under novel design, equivalent structure transformation made based on the specification and figures of the utility model, or directly/be used in indirectly
Other related technical areas are included in the scope of patent protection of the utility model.
