Description
Technical field
This utility model relates to automobile stamping pipe fitting technical field, and specifically a kind of automobile silencing system pipe fitting straight tube is once
Circle_curling die.
Background technology
Automobile stamping pipe shape complex, fit dimension required precision is high, therefore is generally making pipe fitting
Time all use multiple operation technique to carry out rolling up round molding；It is thus desirable to put into multistation, many human users, the equipment of needs is many, accounts for
By substantial amounts of fund, take plant area big, be unfavorable for the development of enterprise；Labor intensive is many, and cost of labor is the highest.Making
During often occur capturing pull at step, garland, molding walk material inequality, upper and lower mould joint windrow, volume circle after dislocation fold
The technical barriers such as material；This will result in making complexity, and producting process difficulty is high, and quality preservation is unstable, and production efficiency is low, produces
Cost is high.
Utility model content
The purpose of this utility model is to provide a kind of automobile silencing circle_curling die of system pipe fitting straight tube, above-mentioned to solve
The problem proposed in background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of automobile silencing circle_curling die of system pipe fitting straight tube, including upper cavity die and lower cavity die, described upper cavity die is installed
On punch press, upper cavity die is positioned at directly over lower cavity die, and lower cavity die centre position is provided with nitrogen spring, and nitrogen spring is arranged over
Plug, the two ends of plug are fixed on plug buoyance lift plate, nitrogen spring drive connection plug buoyance lift plate；Lower cavity die top is provided with floating
Material positioner, tablet is placed in buoyant positioner.
As further program of the utility model: centre position and lower cavity die crown center position bottom described upper cavity die
Offer suitable U-type groove.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, reasonable in design, real
Now disposable volume circle molding, greatly reduces the producting process difficulty of former pipe fitting multiple operation volume circle molding, does not haves and capture platform
Pull at rank, the dislocation problem such as stack after material inequality, upper and lower mould joint windrow, volume circle is walked in garland, molding, reduces and is processed into
This, improve production efficiency, and product with stable quality, and yields is greatly improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-upper cavity die, 2-tablet, 3-buoyant positioner, 4-plug, 5-plug buoyance lift plate, 6-lower cavity die, 7-nitrogen
Air spring.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, a kind of automobile silencing circle_curling die of system pipe fitting straight tube, including upper cavity die 1 and lower cavity die 6, institute
Stating upper cavity die 1 to be arranged on punch press, upper cavity die 1 is positioned at directly over lower cavity die 6, and lower cavity die 6 centre position is provided with nitrogen spring
7, nitrogen spring 7 is arranged over plug 4, and the two ends of plug 4 are fixed on plug buoyance lift plate 5, nitrogen spring 7 drive connection plug
Buoyance lift plate 5, nitrogen spring 7 drives plug 4 raising and lowering；Lower cavity die 6 top is provided with buoyant positioner 3, and tablet 2 is placed on
In buoyant positioner 3.
Further, bottom upper cavity die 1 described in the utility model, centre position and lower cavity die 6 crown center position offer
Suitable U-type groove.
Operation principle of the present utility model is:
Tablet 2 is put in buoyant positioner 3, when punch press moves downward, drive upper cavity die 1 move downward, punch press to
Under move downward during, make tablet 2 contact plug 4, plug 4 rises under the effect of nitrogen spring 7, and upper cavity die 1 is transported downwards
Dynamic, plug 4 moves upward, and tablet 2 is processed into U-shaped with the relative motion of plug 4 by upper cavity die 1.Upper cavity die 1 continues to transport downwards
Dynamic, make tablet 2 continue to move downward, slider of punch moves downwardly to closing point, and tablet volume 2 has been justified.Slider of punch is upwards transported
Dynamic, under the effect of nitrogen spring 7, position replied by plug buoyance lift plate 5, and plug 4 drives product to move back, then taken out by product, complete
Rolling full portion operation.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, this practicality
Novel scope limits by claims rather than described above, it is intended that by the equivalency in claim that falls
All changes in implication and scope are included in this utility model.Any reference in claim should be considered as limit
Claim involved by system.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps
Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should
Description can also be formed those skilled in the art through appropriately combined as an entirety, the technical scheme in each embodiment
May be appreciated other embodiments.
