Description
Technical field
The present invention relates to field of machining, more particularly to a kind of punching press covering trimming fixture.
Background technology
The theoretical calculation of the process of punching press Plastic Forming is very complicated, otherwise it is formed point by CAE software at present
Analysis obtains determining stamping procedure size with reference to or by experience simple computation, no matter but it adopts and how finally all to need
Final process is determined by die trial.
The most common method of the process of final mold is determined by manufacturing mold die trial to complete.Mold is first manufactured,
It repairs a die in die trial, until going out qualified products, this pattern has very wide application.But the covering with flange is come
It says, to determine that the trimming size of the trimming process before flange, die trial process need multigroup die trial parameter, every group of die trial parameter to need
A set of edger, do so obviously it is unreasonable, the method that die trial repairs a die is unworkable.Currently, the featherer before overturning process
The die trial of sequence frequently with method be that edger, but this trimming are remanufactured after trying out suitable dimension by simple fixture trimming
Fixture is usually disposable, and every group of die trial parameter needs a set of simple fixture, to obtain suitable trimming parameter and generally require
Much cover simple fixture.The unnecessary wasting of resources is caused, die trial cost is increased.

In the use of the present invention, again as shown in Figs 1-4, the fixture of the present invention is fixed on wire cutting machine tool workbench
On；Wear silk；According to the two of stamping parts locating piece side centerings；Wire electrode is manually adjusted to suitable position；Place a need
Want the punching press covering of trimming；Programming；Cutting.Remove the punching press covering of trimming completion；A punching press for needing trimming is put again
Covering；It reprograms；Cutting.Multigroup trimming technology parameter can be obtained repeatedly, facilitate follow-up flange die trial or trimming
It draws a design.
In cutting process, detailed fixture working condition is as follows：
For convenience of description, four support shafts 2 are respectively designated as X to support shaft ,-X to support shaft, Y-direction support shaft ,-Y-direction
Support shaft.
When wire electrode close to X to support shaft when, pause cutting, pins 10 of the manual rotation X in support shaft drives X to branch
Axis rotation is supportted, until X is detached to support shaft 2 with embedded nut 7, is then moved X to a section is removed along X to support shaft, really
Protect the advance track for avoiding wire electrode.At this time fixture supporting block 3 still by-X, Y, three directions-Y support shaft 2 constraint, protect
Hold motionless, stamping parts locating piece and punching press covering also remain stationary as.Start to continue to cut, when wire electrode is close to Y-direction support shaft
When, it again pauses for cutting, X is moved inward to support shaft, and pins 10 of the manual rotation X in support shaft, drive X to support shaft
Rotation makes it be connected with corresponding embedded nut 7, then the pin 10 in manual rotation Y-direction support shaft, drives Y-direction support shaft
Rotation, makes it be detached with corresponding embedded nut 7, and Y-direction support shaft is removed a distance along Y-direction manually, avoids electrode
The advance track of silk, starts to continue to cut.P- X is similarly operated to support shaft ,-Y-direction support shaft again successively, until electricity
Polar filament returns to cutting terminating point.In entire cutting process, fixture supporting block 3 is at least by the support of the support shaft 2 in 3 directions
And constraint, it remains static always, punching press covering is also at stationary state, accurate positioning.Punching press covering trimming is completed
Afterwards, the covering after trimming is removed, another covering for needing trimming is put, reprograms, repeats same operation,
Until obtaining multigroup different trimming samples.
In the present invention, support shaft 2 is not limited to setting four, can also be five even more, is with five support shafts 2
Example, five support shafts 2 are arranged at equal intervals centered on fixture supporting block, when cut, similarly square according to above-described embodiment
Five support shafts 2 of formula pair operate, and which is in cutting process at least by the support peace treaty of the support shaft of four direction 2
Beam can keep stablizing in cutting.
In the present invention, holding screw, pin, axle sleeve, embedded nut are can be with firsthand standard component；It in this way can be with
Effectively reduce manufacturing cost.
The advantageous effect that the present invention obtains：
(1) present invention process is good, and manufacture assembles, is easy to maintenance, simple.
(2) good economy performance uses standard component, and special part is few, without selecting expensive mold materials, is manufactured into
This is low.
(3) versatility is good,, only need to be on the basis of this fixture without remaking fixture when punching press covering changes
Replace locating piece corresponding with shape face in stamping parts.
(4) flexibility is good, a sleeve clamp, and multigroup trimming parameter or trimming part can be obtained by changing wire cutting program.
The foregoing is merely a prefered embodiment of the invention, practical range not for the purpose of limiting the invention；If not departing from this
The spirit and scope of invention, modify or equivalently replace the present invention, and should all cover the protection in the claims in the present invention
In range.
