All connection/connection relationships not singly refer to that component directly connects, and referring to can be added deduct according to specific implementation situation by adding
Few couple auxiliary, to form more preferably coupling structure.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
Referring to Fig.1, a kind of step-feeding hole-punching method, including hydraulic pump, at least two forming devices, the forming device packet
Shaping dies, hydraulic cylinder 1 are included, the shaping dies includes spaced fixed board 2, movable plate 3, and the fixed board 2 is equipped with die cavity,
The movable plate 3 is equipped with mold core, and the hydraulic cylinder 1 is sequentially connected with the mold core, the hydraulic cylinder 1 of all forming devices
It is connect in parallel with the hydraulic pump；In the same mold: movable plate 3 is known as movable plate 3 with the position where fixed board 2 is spaced maximum
Lateral limit position, position when mold core is just into die cavity where movable plate 3 is known as critical localisation, and hydraulic pump drives rear moveable plate
3 are known as diastema journey time from the time interval that lateral limit position is moved to critical localisation；At least there are two forming device quilts
It is configured with different diastema journey times.
It can be seen from the above, the present invention provides a kind of step-feeding hole-punching method, it include hydraulic pump, at least two one-tenth shape dress
It sets, in actual processing, settable two rows forming device improves processing efficiency respectively to the both sides simultaneous processing punching of workpiece,
Forming device includes shaping dies, hydraulic cylinder 1, and molding die includes spaced fixed board 2 and movable plate 3, is set on fixed board 2
There is die cavity, workpiece can be put into and be fixed in die cavity, and movable plate 3 is equipped with mold core, and according to workpieces processing needs, the structure of mold core is each
Not identical, hydraulic cylinder 1 and mold core are sequentially connected, and the hydraulic cylinder 1 of all forming devices is connect with hydraulic pump in parallel, same
In mold: the position where movable plate 3 and fixed board 2 are spaced maximum is known as the lateral limit position of movable plate 3, and mold core is just into die cavity
When movable plate 3 where position be known as critical localisation, hydraulic pump drives rear moveable plate 3 to be moved to critical localisation from lateral limit position
Time interval is known as diastema journey time, is at least configured for different diastema journey times there are two forming device, is processing
In the process, pressure suffered by the mold core first contacted with workpiece becomes larger, and pressure is approximately equal to the pressure of hydraulic pump output terminal, which pushes away
Power increases, and in the identical situation of total driving force, red needle can be easily accomplished punching, in this manner, each forming device is arranged
The time contacted with workpiece is different, completes punching one by one, and realizing once can complete multiple punchings to workpiece with lesser motive force
Hole, this delay impact style while realizing punching, can be reduced and be driven using the mutual cooperation between the component of each molding machine

Mold core transmission connection is stated, 6 length of connecting rod at least two forming devices is different, drives simultaneously by the hydraulic pump
The hydraulic cylinder 1 for moving all forming devices starts, and different forming devices produces different diastema journey times, shapes
The length of device inner link 6 is not identical, and other component structure is all the same, and when punching, the longer connecting rod 6 of length pushes mold core, makes
It is first contacted with workpiece, the moment which contacts with workpiece, and suffered pressure increases, until punching is completed, suffered oil pressure
After restoring normal, next forming device starts simultaneously at punching, so repeats, until workpiece is rushed in whole forming device completions
Hole, the method dexterously utilize 6 length of connecting rod different, and mold core reaches workpiece time difference, and the time for completing punching is different,
Realize the effect of delay punching press, and this forming device is lever construction, reaches same impulse force, required driving force is more
It is small, driving force is further saved, the load of driving part is reduced.
It is further used as preferred embodiment, this is embodiment 3, and the pipeline of the hydraulic cylinder 1 and the hydraulic pump connects
The place of connecing is provided with timing valve, and the time of at least two timing valve setting pipeline connections is not identical, passes through the hydraulic pump
The hydraulic cylinder 1 of all forming devices is driven to start simultaneously, when different forming devices produces different diastema strokes
Between, the time that timing valve regulation hydraulic pump driving hydraulic cylinder 1 starts is different, and other component structure is all the same, when punching, hydraulic cylinder
1 first starts, and mold core is pushed first to contact with workpiece, when mold core and workpiece contact, due to the also no starting of other hydraulic cylinders 1, because
Whole oil pressure of the hydraulic cylinder 1 of this starting by hydraulic pump, can easily punch, after the completion of forming device punching, other liquid
Cylinder pressure 1 starts one by one again, so repeats, until whole forming devices complete the punching to workpiece, the method dexterously utilizes liquid
Cylinder pressure 1 starts the difference of time, and mold core reaches workpiece time difference, and the time for completing punching is different, realizes delay punching press
Effect.
