Description
Technical field
This utility model belongs to Stamping Forming of Metal Sheets for Automobile technical field of mold, is specifically related to a kind of flange and ejects
Mechanism.
Background technology
In recent years, along with the development of process industry, stamping die of automotive covering part gets more and more, and structure is more
Come the most complicated, product appearance and prescription more and more higher in the environment of, need one or more replace tradition turn over
Limit ejecting mechanism meets work requirements, it is ensured that product quality, it is to avoid affect complete vehicle quality
Common flange ejecting mechanism structure, it is desirable to the elastic pressure that upper mold is provided by upper mold elastic mechanism than
The elastic pressure that lower mold elastic mechanism provides is big.Bread after flange, on punch, needs flange backing-out punch handle
Plate ejects, but the tension fitted due to the face after lower mold flange and punch, the power that lower mold elastic mechanism ejects
Too small, it is impossible to plate is ejected；If the elastic force of lower mold elastic mechanism is strengthened, this flange ejecting mechanism by
In spacing few, it may appear that unstable phenomenon.
Summary of the invention
This utility model is intended at least to solve one of technical problem present in prior art.To this end, this practicality is new
Type provides a kind of flange ejecting mechanism, it is therefore an objective to optimizes structure and arranges, it is to avoid unstable phenomenon occurs.
To achieve these goals, the technical scheme that this utility model is taked is:
A kind of flange ejecting mechanism, including lower mould body, described ejecting mechanism also includes flange backing-out punch, is located at
The first aeroelasticity telescoping mechanism on lower mould body and for the first aeroelasticity telescoping mechanism is carried out spacing
Fixing fixed mechanism, described first aeroelasticity telescoping mechanism deviates from one end and the flange backing-out punch of lower mould body
Fixing connection.
Described first aeroelasticity telescoping mechanism is the first nitrogen spring.
Described fixed mechanism is fixed block.
Compressing the second aeroelasticity telescoping mechanism by upper mould body makes the second aeroelasticity telescoping mechanism contact also
Flange backing-out punch is driven to be compressed motion.
Described second aeroelasticity telescoping mechanism is the second nitrogen spring.
Described second nitrogen spring is connected with upper mould body by mounting blocks and cushion block, and the bullet of the second nitrogen spring
Property telescopic end stretch out through cushion block.
Described ejecting mechanism also includes for making the second aeroelasticity telescoping mechanism guiding movement to flange backing-out punch
Guide frame.
Described guide frame is gathering sill.
The beneficial effects of the utility model: flange ejecting mechanism operation principle of the present utility model is simple, novel；
The compact in design of each parts, simple and reasonable for structure and attractive in appearance, and reduce die space, meeting work
Efficiency is improve while requirement.Particular, it is important that the most stable during this kind of flange backing-out punch liftout, and
And the nitrogen spring on lower mould body can be bigger than original spring top lift, the work of most of mould can be met
Requirement, is the most great innovation of Press Tools for Automobiles structure design.
Accompanying drawing explanation
This specification includes the following drawings, shown content respectively:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is flange backing-out punch of the present utility model and the second nitrogen spring matched moulds motion structure schematic diagram；
Fig. 3 is flange backing-out punch of the present utility model and the second nitrogen spring die sinking motion structure schematic diagram.
Figure is labeled as:
1, upper mould body, 2, flanging die, 3, flange backing-out punch, the 4, second nitrogen spring, 5, lower mold
Body, 6, fixed block, the 7, first nitrogen spring, 8, cushion block, 9, mounting blocks.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, detailed description of the invention of the present utility model is made into one
Step detailed description, it is therefore an objective to help those skilled in the art that design of the present utility model, technical scheme are had
More complete, accurate and deep understanding, and contribute to its enforcement.
As shown in Figure 1 to Figure 3, this utility model is specifically related to a kind of flange ejecting mechanism, including upper mould body
1 and lower mould body 5, the first aeroelasticity also include flange backing-out punch 3, being located on lower mould body 5 is stretched
Mechanism and for the fixed mechanism that fixes the first aeroelasticity telescoping mechanism, the first aeroelasticity is stretched
Contracting mechanism deviates from that one end of lower mould body 5 is fixing with flange backing-out punch 3 to be connected.Is compressed by upper mould body 1
Two aeroelasticity telescoping mechanisms make the second aeroelasticity telescoping mechanism contact and drive flange backing-out punch 3 to press
Contracting motion.
It is preferred that the first aeroelasticity telescoping mechanism is the first nitrogen spring 7.Fixed mechanism is fixed block 6.
Second aeroelasticity telescoping mechanism is the second nitrogen spring.Spacing by between fixed block 6 and upper mould body 1
Effect, the elastic pressure that can make the first nitrogen spring when arranging is more relatively large than the elastic pressure of the second nitrogen spring
Some, while flange plate ejects, additionally it is possible to make this flange ejecting mechanism more stable.
Wherein, the second nitrogen spring 4 is connected with upper mould body 1 by mounting blocks 9 and cushion block 8, and the second nitrogen
The elastic telescopic end of air spring 4 stretches out through cushion block 8.Specifically, the second nitrogen spring ejects away from flange
Fixing connection is installed by mounting blocks 8 and upper mould body 1 in one end of device 3, by working in coordination with of mounting blocks and cushion block
Clamping action, makes the second nitrogen spring well fix with upper mould body.
In order to make the second aeroelasticity telescoping mechanism guiding movement contact with flange backing-out punch, this flange ejects
Mechanism also includes for making the second aeroelasticity telescoping mechanism guiding movement to the guide frame of flange backing-out punch 3.
Guide frame can be that gathering sill etc. has guiding and do not interferes the structure carrying out contact movement between the two.
Specific works principle of the present utility model:
The matched moulds stage: upper mould body 1 drives downwards, and the second nitrogen spring 4 withstands flange backing-out punch 3, and carries
Dynamic first nitrogen spring 7 starts compression, and compression process avoids flanging die 2, then by flange cutter BOB(beginning of block)
Flange；
In the die sinking stage: upper mould body 1 moves upward, the second nitrogen spring 4 allows sky, the first nitrogen spring 7
Upwards eject, drive flange backing-out punch to move upward, plate is ejected.
Above in association with accompanying drawing, this utility model is exemplarily described.Obviously, this utility model implements
It is not subject to the restrictions described above.As long as have employed method of the present utility model design and technical scheme carried out
The improvement of various unsubstantialities；Or the most improved, above-mentioned design of the present utility model and technical scheme directly should
For other occasion, all within protection domain of the present utility model.
