Abstract
The utility model discloses an air cushion device capable of fast replacing a mold, which belongs to the field of press machine. The air cushion device comprises an air storage tank and an air cushion, wherein the inner cavity of the air cushion is divided into a piston upper cavity and a piston lower cavity through a piston, the piston upper cavity and the piston lower cavity are respectively provided with an air inlet and an air outlet, a two-position five-way electromagnetic valve is arranged between the air storage tank and the air cushion, an air inlet of the two-position five-way electromagnetic valve is connected with the air storage tank, a positive action air outlet of the two-position five-way electromagnetic valve is communicated with the piston lower cavity, a reverse action air outlet of the two-position five-way electromagnetic valve is communicated with the piston upper cavity, and both a positive action air exhaust opening and a reverse action air exhaust opening of the two-position five-way electromagnetic valve are communicated with the atmosphere. When the mold needs to be replaced, the air inlet of the piston upper cavity and the air exhaust of the piston lower cavity are controlled through the two-position five-way electromagnetic valve, a lower mold and a top rod can be fast disengaged, and the replacement of the lower mold is convenient. The utility model improves the machine tool mold replacement efficiency, and saves the mold replacement time.
Description
Technical field
The utility model relates to a kind of air-cushion device of forcing press, belongs to the press technologies field.
Background technology
The air-cushion device of forcing press in the prior art, flanging prevents wrinkling when being mainly used to stretch, also can make liftout or make the locally-shaped usefulness in workpiece bottom, this device mainly comprises air accumulator and air cushion, and the air cushion inner chamber is separated into piston upper chamber and piston cavity of resorption by piston, be respectively equipped with air inlet/outlet on described piston upper chamber and the piston cavity of resorption, piston rod position is corresponding with counterdie, when carrying out punching press, stretch process, and the air inlet of piston cavity of resorption, piston rod stretches out by the push rod in the mould and withstands workpiece, makes workpiece deformation.When needs more during mold exchange, because piston easily is in the top dead-centre state, the push rod that is used for liftout in the mould partly inserts counterdie, can not directly counterdie be removed, and counterdie could be removed after needing push rod taken out one by one, and its die change speed is slow, inefficiency.
The utility model content
But the purpose of this utility model provides the air-cushion device of a kind of quick die change that can overcome above-mentioned defective, and push rod can be descended fast, breaks away from counterdie, so that quickly replacing mould.
But the purpose of this utility model is achieved in that a kind of air-cushion device of quick die change, comprise air accumulator and air cushion, the air cushion inner chamber is separated into piston upper chamber and piston cavity of resorption by piston, be respectively equipped with air inlet/outlet on described piston upper chamber and the piston cavity of resorption, be provided with two-position-five-way solenoid valve between described air accumulator and the air cushion, the air admission hole of two-position-five-way solenoid valve connects air accumulator, the direct action venthole of two-position-five-way solenoid valve and piston cavity of resorption are connected, the reverse action venthole of two-position-five-way solenoid valve and piston upper chamber are connected, and the direct action steam vent and the reverse action steam vent of two-position-five-way solenoid valve are all connected atmosphere.
The utility model adopts two-position-five-way solenoid valve to be connected between air accumulator and the air cushion, when the air inlet of piston cavity of resorption, piston stroking upward, push rod withstands workpiece, when needs more during mold exchange, by the air inlet of two-position-five-way solenoid valve control piston epicoele, the exhaust of piston cavity of resorption, counterdie and push rod are broken away from, made things convenient for the replacing of counterdie.Compared with prior art, the beneficial effects of the utility model are its die change efficient that has improved lathe, have saved mould replacing time.
During for the assurance descent of piston, can jam, cooperate in the described air cushion inner chamber and be provided with upper piston and lower piston, link to each other through piston rod between upper piston and the lower piston, upper piston top is piston upper chamber, the lower piston bottom is the piston cavity of resorption, is arranged with two air inlet/outlets on the piston upper chamber, is provided with three-way connection between the reverse action venthole of this two air inlet/outlet and two-position-five-way solenoid valve.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model fundamental diagram.
Wherein, 1 air accumulator, 2 two-position-five-way solenoid valves, 3 three-way connections, 4,5,9 air inlet/outlets, 6 piston rods, 7 upper pistons, 8 lower pistons, 10 air cushions.
The specific embodiment
As shown in the figure, but air-cushion device for a kind of quick die change, comprise air accumulator 1 and air cushion 10, cooperate in the air cushion inner chamber and be provided with upper piston 7 and lower piston 8, link to each other through piston rod 6 between upper piston 7 and the lower piston 8, upper piston 7 tops are piston upper chamber, lower piston 8 bottoms are the piston cavity of resorption, be arranged with two air inlet/outlets 4 on the piston upper chamber, 5, the piston cavity of resorption is provided with air inlet/outlet 9, be provided with two-position-five-way solenoid valve 2 between air accumulator 1 and the air cushion 10, the air admission hole I of two-position-five-way solenoid valve 2 connects air accumulator 1, the direct action venthole A of two-position-five-way solenoid valve connects two air inlet/outlets 4 of the reverse action venthole B of two-position-five-way solenoid valve and piston upper chamber through air inlet/outlet 9 and piston cavity of resorption, connect through three-way connection 3 between 5, the direct action steam vent P of two-position-five-way solenoid valve and reverse action steam vent O all connect atmosphere.
By direct action venthole A air feed, reverse action venthole B is communicated with atmosphere through direct action steam vent P when normal use, and the piston in the air cushion is in upper dead center position.When the needs mold exchange, two-position-five-way solenoid valve 10 commutations, direct action venthole A is communicated with atmosphere, and by direct action venthole B air feed, air pressure is depressed into bottom dead centre with piston.The fast changeable mould.
