(the data offers: Project of laser of Wuhan China labour is finite liability company) CNC of He Erbi case folds curved Electromechanical fluid synchro control and energy-saving technology CNC are electro-hydraulic and synchronous the machine that fold a turn starts in China later, but develop however in recent years swift and violent. Its core technology: The dependability of system of hydraulic pressure synchro control reachs use state is CNC one of segment with the most important dependability of the machine that fold a turn. CNC is electro-hydraulic synchronism and common the advantage with the more distinct than having the following photograph that twist an axis: 1.
With common the machine that fold a turn relies on torsional canal synchronism of compulsive slide block is different, completely the balance that relies on hydraulic pressure oil path realizes the synchronism that CNC loses curved chance. The control system of complete closed circuit makes the journey of hydraulic pressure oil cylinder is in monitoring and adjusting control condition constantly. Once oil cylinder appears,tilt, issue a statement what CNC is located in the grating feet of oil cylinder both sides with respect to meeting ground is numeric and quickly, make proportioning valve make adjust a movement, make oil cylinder keeps synchronous thereby. 2.
CNC folds curved machine to be able to come true to slant completely hold press press, below the circumstance that in an oil cylinder full load works, pressure of another oil cylinder is 0. 3.
Electro-hydraulic and synchronous system also can make slide block tilts be issued to lower levels, give the work with alterable angle in order to fold a turn, this is common the function that the machine that fold a turn cannot accomplish. 4.
The pressure that electro-hydraulic and synchronous system issues in each working status also is by basis of scale pressure valve the parameter of CNC is self-adjusting. 5.
Movement of electro-hydraulic and synchronous system does not have concussion smoothly, can come true to arrive quickly slow fast transfer smoothly, reduce hydraulic pressure impact, increase systematic stability. 6.
Because the position of oil cylinder is decided by control system, can come true same a pair of mould can have different point of view fold a turn, make the machine that fold a turn becomes a kind flexible machine tool. Can see, do not have factitious element to intervene below the whole job status of the machine that fold a turn, whole journey automation is controlled. Pass CNC parameter to be able to undertake adjust and be correctioned to each operating mode of course. Case of green jade of German congratulate Er (HOERBIGER) outside eliminating the electro-hydraulic and synchronous system that provides all sorts of specification, still develop a pressure to balance the pressure such as amplifier of proportioning valve of module, PVR5eco to balance a technology, can improve a system work efficiency and reduce hydraulic pressure oil to give out heat, come true thereby energy-saving. (the data offers: Case of congratulate Er green jade (without stannum) automation technology limited company) a machining center of efficient fast metal plate connect in Germany fast (TRUMPF) before course of study of Sheet Metal Fabrication of fashionable of metallic plate machining center, turn tower punching machine is the alternative with only people all the time, the impression that its give people is flexible with efficiency. More and more users realize now, open fast linear knife library the efficiency of metallic plate machining center is mixed higher flexible stronger. The main characteristic that opens machining center of plate of metal of CNC of fast hydraulic pressure is as follows: 1.
Structure of unique linear knife library: Mould dimension does not get work size limitation; Pincers dead band is small, the position but with mould crossing-over; The mould changes a pattern, assemble and unassemble convenient and simple, it is only between a few seconds; Expect on convenient, safeguard easily. 2.
Intelligence changes hydraulic pressure drift: 360 ° control all moulds free graduation, do not get work limitation; Electro-hydraulic and direct drive, need not clutch; The hydraulic pressure clamp of the mould can assure to be opposite accurately up and down heart, can machine ≦ even 0.
The board with 5mm large board; Direct control pace develops the trace that receive a knife; Mould but programmed control rotates, can undertake pressing expecting rush and be takinged off makings is strong; Mould length is compensated automatically. 3.
Programmed control workpiece falls makings and flotsam collect: Need not small join, the 100% generation that prevent to carry makings and waste material. 4.
High rate, Gao Rou sex, size range of pipe bent is wide: But the high speed shift of stepless adjustment and pace are strong; The standard locates 2 times function, can machine longer plank; Thin / thick board all can machine, not steel, aluminium board, mild steel and nonferrous metal are like copperplate to wait to also can be machined. 5.
The structure is unique and simple and high grade mould: Mould service life is extremely long; Lubricant function also can lengthen sparge mould life; Use press muscle and shutter figuration mould to be able to undertake the pace develops form cutting; Mould sort is rich, get used to all sorts of products. Rush besides the pace and outside floating rate, the machine tool develops the scale that cuts time to occupy whole working hours actually is the mainest factor that the user should care. Well-known, the whole working hours of the user comprises by this a few parts: Fluctuation makings time (occupy whole working hours 10% ) ; Assist time, include process designing to wait (those who take whole time 10% ) ; The mould assembles and unassemble time; Rush actually cut time. Turn the mould of tower punching machine assembles and unassemble time and machine goods lot have very big concern. According to statistic, to product of lot of moderate size, the mould assembles and unassemble 45% what time occupies whole working hours, accordingly, rush actually cut time to be occupied only 35% . Expect time and auxiliary time suffer the effect of goods lot scarcely up and down, the proportion that both the sum holds whole working hours is 20% . Apparent, the mould assembles and unassemble time proportion is smaller, strong cut time place to hold proportion taller. The structure of linear knife library that because other is distinctive,opens machining center of fast metal plate has a structure with the model, the mould assembles and unassemble the proportion that time holds whole working hours is very small, and the effect that does not get goods lot basically, this value is 5% , because this rushs actually,cut time to be as high as 75% . Namely, rush quickly cutting time is traditional turn tower punching machine is 2 times what cut time stronger.
