It is of the invention the invention also discloses a kind of double-plate hydraulic press, including mode transfer clamping of the present invention
In the double-plate hydraulic press that mode transfer clamping is particularly suitable for use in vertical, it can be used in other similar devices.
The original state of the mode transfer clamping of the present invention is die opening state, the wherein rod chamber room 51a of lift cylinder 51
（Lower chambers i.e. in accompanying drawing）Oil is suppressed, the rod chamber room 61a and rodless cavity room 61b of master cylinder 61, which are in, freely leads to oil condition, embraces
Close nut 71 and be in releasing orientation, the piston rod 82 of ejection cylinder 81 is in receiving state, i.e. portable plate 83 is in groove 621
It is interior.The mode transfer clamping of the present invention is as follows from original state to the process for completing mode transfer mould assembling action（The wherein He of fixed mold 91
Moving mold 92 is fixed on top clamping plate 2 and portable plate 62 accordingly）.
The first step, the rod chamber room 51a oil extractions of lift cylinder 51, the 51b oil suctions of rodless cavity room, Bottom clamp plate 3 and activity
Plate 62 is declined until two moulds are bonded by conducting oneself with dignity；
Second step, Bottom clamp plate 3 continue to decline, until the upper surface of the piston rod 611 of master cylinder 61 and rodless cavity room 61b
Top fitting, now be Bottom clamp plate 3 decline extreme lower position；
3rd step, the rodless cavity room 61b oil-feeds of master cylinder 61, due to portable plate 62 is leaned by the mould of lower section can not
Move down, now, Bottom clamp plate 3 is promoted under the driving of master cylinder 61 to be risen, and is detected and moved by displacement transducer
Until reaching cohesion nut 71 and the tooth form of pull bar 1 can stop during obvolvent, cohesion nut 71 passes through obvolvent oil cylinder for the position of die holder plate 3
Altogether so that cohesion nut 72 and pull bar 2 are locked, now, Bottom clamp plate 3 is in locking state；
4th step, the rodless cavity room 61b oil-feeds of master cylinder 61, now, because Bottom clamp plate 3 is in locking state, main oil
Cylinder 61 is that portable plate 62 provides downward power, forms clamp force；
5th step, after the processing for completing workpiece, the rod chamber room 61a oil-feeds of master cylinder 61, now, the driving of master cylinder 61 are lived
Dynamic plate 62 and moving mold 92 upwardly open slightly, i.e., micro-shifting is dynamic opens mould；
6th step, micro-shifting move Qi Mohou, and obvolvent oil cylinder opens cohesion nut 71, and Bottom clamp plate 3 is in movable state,
Now, the rod chamber room 51a oil-feeds of lift cylinder 51, lift cylinder 51 drive Bottom clamp plate 3 and portable plate 62 to move upwards,
Complete die sinking action；
7th step, ejection cylinder 81 drive liftout plate 83 to stretch out groove 621, will be withdrawn after the workpiece ejection of processing, i.e., complete
Into a production cycle.
The both ends of pull bar 1 of the present invention are fixed by top clamping plate 2 and fixed mount 4 respectively, and pull bar 1 is constantly in fixing shape
State, substitute tradition and be finely adjusted by pull bar.Substitute pull bar mode transfer, the present invention is realized by master cylinder 61 and portable plate 62 and adjusted
Mould, when portable plate 62 is in extreme lower position（I.e. mould mutually leans）When, master cylinder 61 can drive Bottom clamp plate 3 to transport upwards
It is dynamic, the fine setting of Bottom clamp plate 3 can be achieved, when reaching relevant position, Bottom clamp plate 3 is locked, after the locking of Bottom clamp plate 3, main oil
Cylinder 61 can also apply coupling mechanism force to portable plate 62, form clamp force, master cylinder 61 can not only realize mode transfer function but also can produce lock
Mould power, the stability and guidance quality that must take into consideration during relatively conventional pull bar mode transfer, the present invention only need to pass through elevating mechanism 5, main oil
Cylinder 61 and obvolvent mechanism 7 achieve that mode transfer and matched moulds, and mechanism stable, the structure letter of the present invention are caused plus fixed pull bar 1
It is single, and cost can be reduced.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as
Protection scope of the present invention.
