Stopper rod is fixedly connected with floating template, and driving floating template is slided up and down along lower guide post, and being provided centrally with for floating template is logical
Hole.
Using the technique of above-mentioned full-automatic molding hydraulic press compacting multi-step dry powder product:
(1) mold is installed
The upper punch of compacted products will be needed to be mounted on cope plate, interior bottom punch is mounted in secondary float plate, outer lower floating die
Punching is mounted on floating template, and former is mounted in former hole, and when initial bit, former, interior bottom punch, outer lower floating die are rushed to summit portion
Concordantly.
(2) it feeds
The lower lower beam living of oil cylinder driving moves up, and former moves up, and forms the charging height of interior bottom punch, and floating cylinder drives on floating template
It moves, outer lower floating die rushes to shifting, forms the charging height of outer lower floating die punching, i.e. charging position, automatic feeding send powder
Enter in negative impression.
(3) it suppresses
The cope plate that upper oil cylinder driving is mounted on beam living drives and is advanced into former mouth under upper punch, will have been charged into negative impression
Powder " Feng Mo ", upper punch continue to push under the action of upper oil cylinder, at the same former, the punching of outer lower floating die respectively lower oil cylinder,
It is moved down under the action of floating cylinder, the opposite of interior bottom punch is achieved and moves up, presses upwards, in upper punch, interior bottom punch
It is two-way that dynamic pressure system is floated downward to pressure active force, until molding position, " pressure maintaining ", " pressure release ", product compression moulding.
(4) it demoulds
Beam of living in upper oil cylinder driving moves up, and drives upper punch backhaul, moves down with the lower beam of living of the driving of oil cylinder at present, former moves down, and floats
Dynamic cylinder driving floating template moves down, and outer lower floating die sweeps away shifting, until former, interior bottom punch, outer lower floating die are rushed to summit, portion is concordant, i.e.,
Position is demoulded, bottom punch interior so just ejects shaped article outside negative impression, realizes product stripping, a technological action circulation knot
Beam；Complete the compacting of multi-step dry powder product.
The technique that two layers of dry powder product is suppressed using above-mentioned full-automatic molding hydraulic press:
(1) mold is installed
The upper punch of compacted products will be needed to be mounted on cope plate, bottom punch is mounted in secondary float plate, and former is mounted on yin
It is concordant at the top of former, bottom punch when initial bit in die hole.
(2) it feeds
The lower lower beam living of oil cylinder driving moves up, and former moves up, while secondary charging cylinder drives secondary float plate to move up, on bottom punch
It moves, forms the primary charging height of bottom punch, the first powder is sent into negative impression by automatic feeding, upper oil cylinder driving installation
It is advanced into former mouth in the case where the cope plate on upper beam living drives upper punch, by the powder " Feng Mo " for having been charged into negative impression while being carried out
" precompressed ", after the completion of precompressed, beam of living in upper oil cylinder driving is moved up, and drives upper punch backhaul；Secondary charging cylinder drives secondary floating
Plate moves down, bottom punch backhaul, forms the secondary charging height of bottom punch, and the second powder is sent into negative impression by automatic feeding
It is interior.
(3) it suppresses
The cope plate that upper oil cylinder driving is mounted on beam living drives and is advanced into former mouth under upper punch, will have been charged into negative impression
Second powder " Feng Mo " carries out " precompressed " simultaneously, and after the completion of precompressed, upper punch continues to push under the action of upper oil cylinder, while yin
Mould moves down under the effect of lower oil cylinder, the opposite of bottom punch is achieved and moves up, presses upwards, in upper punch, interior bottom punch
It is two-way that dynamic pressure system is floated downward to pressure active force, until molding position, " pressure maintaining ", " pressure release ", product compression moulding.
(4) it demoulds
Beam of living in upper oil cylinder driving moves up, and drives upper punch backhaul, moves down with the lower beam of living of the driving of oil cylinder at present, and former moves down, until
Concordant at the top of former, bottom punch, i.e., demoulding position, product stripping, a technological action circulation terminate；Complete two layers of dry powder product
Compacting.
Certainly, the product of multilayer difference dry powder can also be suppressed using the application hydraulic press, only need repeatedly floating two downwards
Secondary floating template sequentially adds different dry powder；The even product of more multilayer difference dry powder, along with installation is floated
Outer bottom punch cooperation in template.
