Smooth board jacket has pincers of 2 hydraulic pressure (see a picture 5) . Basis board stuff is real punching position, fix logical pincers place, avoid relocation as far as possible in order to improve punching efficiency, the position of pincers wants the pincers position with software of automatic process designing to answer relatively. Graph Nextpage4 of pincers of 5 hydraulic pressure. Y axis sends into device to be Y axis along definition of direction of board makings width, y axis sends into device by send into the composition such as base, slideway, towline, towline wearing and lower margin bolt. By drive of servo electric machinery, accurate ball guide screw and slideway slide block are oriented. Develop the effect of vibration of the lead plane in reducing a process to punching precision to decrease, y axis sends be depart into device base and lathe bed. 5. Pneumatic system this machine pneumatic system yuan the pneumatic cell that parts of an apparatus uses German FESTO firm, include to enrage a source to handle unit, air cylinder, hand to accuse reversal valve, electronic-controlled switch of reversal valve, pressure-relief valve, pressure, air gun and tracheal wait for component. The processing system that enrage a source filters precision is 40mm, pressure of source of requirement plant energy of life not under 0.

5MPa, pressure of set of system of route of the gas when leaving factory is 0.

5MPa. In working process, if pipeline is baric under 0.

45MPa, systematic clew atmospheric pressure is too low call the police, the system quits the job. The executive component of this machine pneumatic system is air cylinder of 7 air cylinder that change a pattern, 7 drift restoration and a fixed position annul drive air cylinder. Condition of go back of the air cylinder that change a pattern does not choose a mould, extend condition to be choice mould, this engine control system does not allow two air cylinder to be in at the same time reach position. Air feed of the antrum on air cylinder of restoration of 7 drift when the machine tool works, assure every time the drift after punch is finished sticks close punch, assure to change when next mould, the blow space block that the air cylinder that change a pattern drives can reach the designated position smoothly. 6. System of hydraulic pressure of hydraulic pressure system includes piece of relay of watch of gasoline tank, hydraulic pump, electric machinery, accumulator, condenser, pressure, pressure, a powerful person and pipeline to wait. Have the aid of of hydraulic pressure system completes all sorts of actions at the control of numerical control system (see a picture 6) . Graph after electric machinery of principle of 6 hydraulic pressure is started, hydraulic pump begins the work, YV1, YV2, YV3, YV4 and YV5 all do not get report, a powerful person of electromagnetism of hydraulic pressure oily classics 7, condenser 5, oil purifier 4 oil sump tank, the system is condition of discharge carry on one's shoulder. If electric contact pressure is expressed 14 detect pressure of pincers oil path under 7MPa, YV3 gets report, oil pump offers oil for this oil path; Fill after approaching proper time, oil path pressure achieves 10MPa, YV3 breaks phone, pilot valve 7 in returning, the system is in condition of discharge carry on one's shoulder.
