Abstract
The utility model discloses a kind of flange punching die; relate to mould applications; this programme is proposed; mainly include upper die mechanism and the lower die mechanism being oppositely arranged up and down; described upper die mechanism includes the cope match-plate pattern that cylinder drives; it is fixed with die in cope match-plate pattern lower surface; described lower die mechanism includes the lower bolster being fixed on pedestal; this lower bolster is provided with low mold frame; this low mold frame is corresponding with flange spring catch; in low mold frame, be sliding combined with material returned mould, this material returned mould have spring upwards against, with realize flange punching one function.
Description
Technical field
This utility model relates to a kind of flange punching die, relates generally to mould applications.
Background technology
An existing part needs by mould it to be carried out deburring and the limit fixed is carried out flange, simultaneously need to former material
It is punched out in the middle part of material.Existing mould at least needs to use two secondary moulds, and wherein raw material is repaiied by a secondary mould
Limit and flange, another secondary mould carries out middle part punching.Use this scheme, on the one hand can strengthen machining tolerance, on the other hand
Working (machining) efficiency has been had a strong impact in many secondary mould exchange processing.
Utility model content
For above the deficiencies in the prior art, the utility model proposes the flange punching die of a kind of flange punching one.
For reaching above-mentioned purpose, the technical solution of the utility model is: include the upper die mechanism that is oppositely arranged up and down and under
Mold mechanism, described upper die mechanism includes the cope match-plate pattern that cylinder drives, and is fixed with die in cope match-plate pattern lower surface, in the middle of described die
It is provided with flange gap between being vertically sliding combined with on the downside of material returned spring catch, die and material returned spring catch, sets at die excircle
Having and upper framed be fixed on cope match-plate pattern, be sliding combined with flange spring catch between upper framed and die, described lower die mechanism includes
The lower bolster being fixed on pedestal, this lower bolster is provided with low mold frame, and this low mold frame is corresponding with flange spring catch, in low mold frame
Be sliding combined with material returned mould, this material returned mould have spring upwards against, in the middle part of material returned mould, be vertically provided with pin-and-hole, in pin-and-hole
Being sliding combined with punching pin, the bottom of punching pin is fixed on lower bolster, and punching pin is correspondingly arranged with material returned spring catch.
Know-why of the present utility model is as follows: processing when, first upper die mechanism and lower die mechanism is in separation
State, is placed on raw material lower die mechanism upper end, is then driven downwards by upper die mechanism by driving means, work as upper die mechanism
When touching raw-material, pressing under continuing, upper framed and low mold frame relative movement, to carrying out trimming, the material returned around raw material
Spring catch is upwards made a concession, low mold frame and die relative motion, and raw material will be to upper overturning, and flange is positioned at die and material returned spring catch
In flange gap between Xia Ce, material returned mould moves downward, and punching pin is motionless, and material returned mould moves relative to punching pin, and then is formed
Punching.The operation of flange and punching is achieved above in a secondary mould.
The beneficial effects of the utility model are as follows: use this programme, on the one hand improve the precision of work pieces process, reduce
Machining tolerance, uses a secondary mould to complete two operations, it is possible to effectively to improve working (machining) efficiency simultaneously.
Further, be sliding combined with stripper ring at low mold frame outer circumference surface, this stripper ring by spring upwards against, complete
Leftover pieces can be projected out by stripper ring when of trimming.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
In description, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only that this practicality is new
Wherein two width of type, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to root
Other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the structural representation that this utility model embodiment upper die mechanism separates with lower die mechanism；
The structural representation that Fig. 2 is the upper die mechanism of this utility model embodiment and lower die mechanism is closed up.
Wherein, 1-cope match-plate pattern, 2-is upper framed, 3-flange spring catch, 4-die, 5-material returned spring catch, 6-low mold frame, 7-
Material returned mould, 8-punching pin, 9-lower bolster, 11-stripper ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in this utility model is clearly and completely described, it is clear that retouched
The embodiment stated is only preferred embodiment of the present utility model rather than whole embodiments.Based in this utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all
Belong to the scope of this utility model protection.
Embodiment
As it is shown in figure 1, this utility model embodiment includes upper die mechanism and lower die mechanism.
This upper die mechanism includes be fixed on cope match-plate pattern 1 lower surface upper framed 2 and the die 4 being arranged in framed 2,
Upper between framed 2 and die 4, be provided with flange spring catch 3, on the downside of flange spring catch 3 and die 4 between be provided with flange gap, shape
The flange become is positioned at herein.Material returned spring catch 5 vertically it is provided with in die 4.
This lower die mechanism includes the low mold frame 6 being fixed on lower bolster 9, and the outer circumference surface in low mold frame 6 is sliding combined with
Stripper ring 11, this stripper ring 11 by spring upwards against, in low mold frame 6, be sliding combined with material returned mould 7, material returned mould 7 times
Portion be provided with spring by material returned mould 7 upwards against, be vertically provided with punching pin 8, the bottom of this punching pin 8 at middle part at material returned mould 7
It is fixed on lower bolster 9,
Flange spring catch 3 and low mold frame 6 are correspondingly arranged, and material returned spring catch 5 and punching pin 8 are correspondingly arranged.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
