Description
Technical field
The present invention relates to a kind of mechanical mechanism for diel and diels, more particularly to one kind being used for component
The mechanism and mold of delayed ejection.
Background technology
Drawing die is the key component of all types of diels, is the first working procedure of all kinds of part punching formings, master
It includes punch-pin, cavity plate and blank holder to want building block.During using die forming, by blank holder and cavity plate by tablet pressure
Tightly, then by punch-pin and cavity plate by tablet draw forming.
In the prior art, it for the deep drawn part of moulding complexity, needs to float in punch-pin and cavity plate interior design and press
Expect core, the auxiliary control flowed for tablet in forming process.In general, actual production conditions, floating binder are limited to
Core needs to meet following demand：
During draw forming, floating material pressing core needs to provide steady and sustained pressure-pad-force, and tablet is compressed；
After draw forming, mold is opened, and floating material pressing core can not eject immediately, otherwise can be askew by part top, shadow
It rings manipulator and captures part；
After manipulator takes the part that forming finishes away, floating material pressing core needs rapid ejection, thus to draw next time
Prolong forming to be ready；
After punching parts produce, mold is moved in warehouse out of press and stores, and mould inside need to place one
Part after drawing, floating material pressing core at this time need to keep compressive state, otherwise can be askew by part top, influence under mold
A batch of production.
Presently, there are there is the floating material pressing core with delayed ejection function, but this kind of delayed ejection is by automatically controlled or gas
The one-way flow for controlling check valve control delay nitrogen gas spring internal gas, to realize that the ejection of delay nitrogen gas spring acts delay
Controllably, and then achieve the purpose that floating material pressing core delayed ejection, but find in practical applications, it is this only to pass through nitrogen gas spring
There are still some disadvantages for the floating material pressing core of realization delayed ejection, such as：
1) nitrogen gas spring pressure and stroke are non-adjustable：Since the operation principle of existing delay nitrogen gas spring prevents it from picture
Ordinary nitrogen spring is the same, changes pressure by adjusting internal gas-storing capacity, therefore its impulse stroke must be with rated travel phase
Deng without having adjusting surplus；
2) delay nitrogen gas spring ejection speed is slow, it is difficult to meet high jig frequency demand：Due to existing delay nitrogen gas spring top
When going out, all gas or medium have to flow through automatically controlled or gas control check valve, and flowing velocity is limited, cause it to eject speed and are unsatisfactory for
The punching production requirement of high beat；
3) the nitrogen gas spring fever of delay nitrogen gas spring is serious, and there are security risks：Since delay nitrogen gas spring is worked
A large amount of heat is generated in journey, heat dissipation will substantially shorten the nitrogen gas spring service life when insufficient, or even can influence mold damage；
4) delay nitrogen gas spring is bulky, is unfavorable for arranging：Since this kind delay nitrogen gas spring needs optional equipment
Corresponding delay control system and cooling system, cause own vol huge, difficult for the floating material pressing core of small volume
To install arrangement；
5) kinetic stability of delay nitrogen gas spring is poor, and debugging is difficult：Since this kind postpones the ejection speed of nitrogen gas spring
And ejecting force is determined by the gas flow that gas or medium flow through the flow velocity of check valve and have passed through check valve, thus, make
It is not definite value, poor controllability that must postpone the ejection speed of nitrogen gas spring and ejecting force；
6) under mold storing state, delay nitrogen gas spring cannot keep compression：After production, mold is by press
It is moved in warehouse and stores, all outer signals are removed at this time, automatically controlled or gas control failure of check valve, the delay of nitrogen gas spring
Locking function also accordingly disappears, at this point, floating material pressing core can be caused to be ejected.
7) delay nitrogen gas spring is expensive：It is it since this kind delay nitrogen gas spring production and purchase cost are high
Five to ten times or more of same specification ordinary nitrogen spring, thus so that the delay nitrogen gas spring price that a secondary drawing die uses
Often as high as hundreds thousand of members.
Based on this, it is expected that the shortcomings that obtaining a kind of Delayed ejection mechanism, existing delay nitrogen gas spring can be overcome.
