First upper holder block (4.2.3) resets upwards.
4. flexible perforating press according to claim 2, it is characterised in that the drift (4.2.10) include pierce punch and
The cut-out class of drift two；
For the n drift that n roads punching unit (4) are used, by sheet material direction of advance, preceding n-1 drift be for
The pierce punch of punching on sheet material；Last drift is the cut-out drift for cutting off sheet material.
5. flexible perforating press according to claim 1, it is characterised in that n is equal to 6.
6. the flexible perforating press system of flexible perforating press described in a kind of application claim any one of 1-5, including：Uncoiler feeding
Device, leveling apparatus and flexible perforating press；The uncoiler feed device, the leveling apparatus and the flexible perforating press
It is sequentially connected.
7. the flexible hole-punching method of flexible perforating press system described in a kind of application claim 6, it is characterised in that including following step
Suddenly：
Step 1, by sheet material conveying direction, sets gradually uncoiler feed device, leveling apparatus and flexible perforating press；
Wherein, flexible perforating press includes symmetrical left punching system and right punching system；Left punching system includes：Left punching
Lower mould supporting plate, left hydraulic cylinder supporting plate, the left punching unit in n roads, left servomotor and the ballscrew that rolls left；Right punching system bag
Include：Mould supporting plate, right hydraulic cylinder supporting plate, the right punching unit in n roads, right servomotor and right ball-screw under right punching；
The left punching system includes the left punching unit in n roads, by sheet material conveying direction, the 1st road punching unit, the 2nd is designated as successively
The n-th road of road punching unit ... punching unit；The right punching system includes n roads punching unit, by sheet material conveying direction, remembers successively
It is the 1st ' road punching unit, the road punching unit of the 2nd ' road punching unit ... the n-th '；On sheet material conveying direction, adjacent punching unit
Between spacing and hole on sheet material between spacing it is identical and immobilize；According to the shape in hole to be gone out on sheet material, each road is determined
Drift and the type of lower mould that punching unit is used；
Step 2, uncoiling is carried out by uncoiler feed device to coiled sheet material；The sheet material after uncoiling is carried out by leveling apparatus again
Smoothing；Sheet material after smoothing is fed by the charging length of setting, meanwhile, control left servomotor and the right side to watch respectively by setup parameter
Take motor action；Mould supporting plate carries out left and right directions under the left servomotor drives the left punching by the ballscrew that rolls left
It is mobile, and then make the drift of the left punching unit in n roads positioned at the surface of sheet material left side setting position；The right servomotor passes through
Mould supporting plate carries out the movement of left and right directions under right ball-screw drives the right punching, and then makes rushing for the right punching unit in n roads
Head is located at the surface of sheet material right side setting position；Now, the left side of sheet material is between mould on mould under left side and left side；Sheet material
Right side be located under right side on mould and right side between mould；
Step 3, according to punching quantity demand, controls the hydraulic cylinder downward actuation setpoint distance of the left punching unit in m roads, makes in sheet material
M hole is gone out in left side simultaneously；Wherein, m is less than n, and m is natural number；Control the hydraulic cylinder downward actuation setting of the right punching unit in m roads
Distance, makes on the right side of sheet material while going out m hole；
Wherein, the action process of left punching unit or right punching unit is：
During the piston rod downward actuation of hydraulic cylinder, hydraulic cylinder attaching nut, adjustment block, the first upper holder block, the second upper holder block are promoted
The single piece downward actuation setpoint distance formed with the 3rd upper holder block；When single piece downward actuation setpoint distance, by connection
Mould downward actuation in the resiliency urged of spring, upper mould directly contact sheet material simultaneously applies flexible force, and then sheet material is downward to sheet material
Flexible pusher realizes the fixation to sheet material to the surface of lower mould；Meanwhile, drift acts on downwards sheet material, to sheet material correspondence
Position punching；Then, the piston rod of hydraulic cylinder acts reset upwards, and then drives punching to be resetted away from sheet material, thus completes
One-off hole-piercing；
Step 4, after sheet material continues to be fed to required length, by controlling left servomotor and right servomotor actuating quantity, you can
Adjustment left and right sides pitch of holes to be formed on sheet material, repeats execution step 3, and sheet material is punched out.
