Description
Technical field
The present invention relates to a kind of machined die field, and in particular to a kind of blanking die.
Background technology
Blanking die is indispensable technological equipment in punching production, and good mould structure realizes process program
Reliable guarantee.Quality and the precision height of punching parts, depend primarily on the quality and precision of blanking die.Blanking die
Whether structure is reasonable, advanced, has a direct impact safe, side to production efficiency and blanking die service life in itself and operation
Just property etc..Because blanking part shape, size, precision and production batch and working condition are different, the structure type of blanking die is not yet
Together.Current blanking die stills need to improve in terms of precision and efficiency.
The content of the invention
To solve deficiency of the prior art, the present invention provides a kind of guiding accuracy height, a kind of high punching of production efficiency
Mould.
In order to realize above-mentioned target, the present invention is adopted the following technical scheme that：A kind of blanking die, including upper die structure is with
Mode structure, upper die structure includes the upper bolster with die shank, and punch retainer, punch-pin, punch retainer are connected with upper bolster, under
Mode structure include die shoe, cavity plate, stock guide, pin stop and the stripper playing the guiding role, the cavity plate be arranged on it is described under
Above die holder, the stock guide is located on the cavity plate, is flexibly connected with the cavity plate, between the punch-pin and the stripper
There is gap, upper and lower intermode can coordinate by the gap of the punch-pin and the stripper to be oriented to.
Preferably, the fit clearance of the stripper and the punch-pin is less than clearance between punch and die.
Preferably, the upper die structure also includes guide pin bushing and guide pillar, and the upper bolster is provided with upper bolster hole, the guide pillar
It is interference fitted, coordinates between the guide pillar and the guide pin bushing for interval with upper bolster hole.
Preferably, the die shoe is provided with die shoe hole, and the guide pillar is interference fitted with the die shoe hole.
Preferably, the stripper is oriented to stripper for rigidity.
Preferably, it is provided with banking pin on the stripper.
Preferably, the banking pin is two.
The beneficial effect that the present invention is reached：Due to the setting of the present invention, make guiding accuracy of the present invention high, production efficiency
It is high.
Brief description of the drawings
Fig. 1 is the cross section structure diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
A kind of blanking die, including upper die structure and lower die structure, upper die structure include the upper bolster 2 with die shank 1, convex
Mould fixed plate 3, punch-pin 4, guide pillar 5 and guide pin bushing 6, punch retainer 3 and upper bolster 2 can be bolt connections, and upper bolster 2 is provided with
Upper bolster hole, guide pillar 5 is interference fitted with upper bolster hole, is coordinated between guide pillar 5 and guide pin bushing 6 for interval, and lower die structure includes die shoe
7th, cavity plate 8, stock guide 9, pin stop 10 and the stripper 11 playing the guiding role, stripper 11 are oriented to stripper, rigidity for rigidity
Being oriented to the design of stripper can make workpiece realize automatic leakage in cavity plate hole.Equipped with two banking pins on stripper 11
12, die shoe 7 is provided with die shoe hole, and guide pillar 5 is interference fitted with die shoe hole, and cavity plate 8 is arranged on the top of die shoe 7, guide
Plate 9 is located on cavity plate 8, is flexibly connected with cavity plate 8, there is gap between punch-pin 4 and stripper 11, and stripper 11, which has to be oriented to, to be made
With upper and lower intermode can coordinate by the gap of punch-pin 4 and stripper 11 to be oriented to.In blanking process, material leans on stock guide 9
Realize and be properly positioned with pin stop 10, to ensure that edge-lapped value is consistent in blanking process, punch-pin 4 keeps matching somebody with somebody all the time with stripper 11
Splice grafting is touched, and the fit clearance of stripper 11 and punch-pin 4 is less than clearance between punch and die, to ensure mould guiding accuracy.Above-mentioned blanking die
The design of tool makes to be integrally improved guiding accuracy, also improves production efficiency.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these improve and deformed
Also it should be regarded as protection scope of the present invention.
