As microelectronics and computer technology increasingly mature, promoted the development of technology of our country numerical control, system of homebred numerical control develops a success in succession, make machine tool of our country numerical control is on character, got ensuring on function. Because numerical control machine tool is having precision of strong to the adaptability of workpiece remodel, treatment tall, raise the characteristic such as productivity, because this received promotion application in each domain. Numerical control technology got applied extensively on Ban gold machine tool, the spare parts precision that it solved the existence in Sheet Metal Fabrication tall, appearance complex, batch is big wait for a problem. Machine tool of gold of numerical control Ban includes punching machine of machine of Laser Cutting of numerical control plane shear, numerical control, numerical control, numerical control curved trigger, solder machine of cut of machine, blaze. The application of their aborning increased capacity of Sheet Metal Fabrication greatly, make Ban gold go up in quality, get assuring on crop, at the same time also greatly the labor intensity that reduced a worker. Cut board next makings are the first working procedure in process of Sheet Metal Fabrication, the accuracy that expects below is affected directly from the back the treatment quality of working procedure, the dimension that the application of numerical control plane shear assured next makings and the work of next makings diagonal are poor. Numerical control plane shear is by numerical control device, servo, measurement unit and machine tool are comprised. Servo is by 3 servo electromotor and servo actuating device are comprised. The fixed position before the machine tool has two servo electric machinery, normally one advocate electric machinery works alone, size range of pipe bent 2, 500mm, if machine deputy electric machinery of bevel edge criterion to work, numerical control system gives out two different instructions form bevel edge. Fixed position has electric machinery of a servo after, main treatment is big the product of board face, size range of pipe bent 150 ～ 4000mm. If Shanghai produces plane shear of QC12K series numerical control to provide set of Swiss CYBELEC DNC60,can store 36 order, interior stores memory measures 100 order. S punch is an important segment in Sheet Metal Fabrication, numerical control punching machine can replace the past the process capability of 3 punching machine. Improved productivity greatly. Numerical control punching machine is the machine tool with a kind of extensive use, drift having sheet and turn tower two kinds. The article with CNC1000 model for exemple, italy of producing area of this machine tool. Belong to the machine tool of C structure, size range of pipe bent: 1270 × 1000mm, turn the tower has 19 moulds to be versed in, the below two parts on cent fit the punch of the mould and sunken pattern respectively, sunken model external dimension diameter 25.

00mm, numerical control punching machine has axis of X, Y, Z3 commonly. X axis is a machine tool 0 degrees of direction, y axis is a machine tool 90 degrees of direction, z axis installation is turning is the apparatus that controls mould angle on the tower. Machine tool handlers decides according to part drawing and craft requirement treatment program writes program sheet. Handlers passes the operation face plate of the machine tool, write the program into program memory directly in EDIT means; As the development of CAD/CAM and CIMS chance method, operator can pass the computer relevant software inputs the graph the generating program inside the computer, beat inputs numerical control system through disk drive into disk. Still can use the computer and numerical control system serial methodological input. The process designing of numerical control punching machine dictates cent is code of G code M, g code is the function that uses instruction machine tool to undertake machining motion and interpolation means. Like G91 increment pace of punching of arc of absolute command of command, G90, G29, G68 develops garden arc. M code is the code that dictates the machine tool makes a few auxiliary motions. If M30 program stops. After checking program is proper, loose caliper puts workpiece to shut caliper. Starting oil pump and drift carry out a program to complete treatment. Numerical control punching machine has the following characteristic: (1) is full automatic concentration is lubricant; (Mould of 2) punching machine cools automatically and lubricate (overweighted protector screen shows 3) hydraulic pressure and install automatically afresh; (4) matchs stock pneumatic / hydraulic pressure operation presses force board makings to place changeably; (5) can prop up the especially big workbench that big template expects in the round; (6) tall accuracy, the punching machine of hydraulic pressure numerical control of high speed low noise; (7) can be simple and easy the slip workbench that undertakes the mould changes to be interlinked with safety; (8) gets together device of ball of ammoniac fat freedom, avoid material face cut. Numerical control punching machine machines craft to have the following characteristic: Treatment precision is tall. Kong Bian is apart from labour to differ 0.

2mm, pitch work is poor 0.

5mm/m. Because turn,tower jacket has a variety of patterns, make workpiece installs clip to finish full treatment content instantly. The machine tool can be machined alone to workpiece or use group of command G98 to be machined to workpiece batch, improve productivity. Workpiece is in experienced next makings, punch the working procedure that fold a turn arrives after two working procedure. Numerical control bends trigger to having the advantage that general accuracy machine tool cannot compare. Be like Italy of CASPRINI producing area, system of Xi Menzi numerical control, input method is manual process designing, (1) input directly through Control Panel board height of length of dimension of axis of date of thick, mould, tensile strength, X, angle, workpiece, journey will finish write. (2) the work with high demand of complex to a few appearance precision inputs 2D or 3D graph through Control Panel, board thick, mould date benefit defines generating program of the order that fold a turn with the function of man-machine interaction. After the program is generated, deposit the area is filled in program delay inside, if will be used even henceforth,deposit inside machine tool memory, if the program needs to be used repeatedly in great quantities should give backup through special disk beat. Numerical control curved trigger has around normally two pull work or material rest, by numerical control system control root refus folds curved angle to pull work or material rest to admire a height certainly, reduced the labor intensity of handlers so. Common numerical control curved trigger has axis of the X axis of machine tool of drive of two servo electric machinery, Y. Detect package adopts grating rule, inductive synchronized, coder normally installation is on the guide screw of the machine tool, detect feedback device changes the displacement volume of guide screw into telegraphic date, and feedback gives numerical control unit, if be worth with the instruction,have 0.

02mm error, control guide screw to make adjust. High-powered curved trigger installs an electric machinery each in X axis both sides, make X axis can machine bevel edge. On the axis each install an electric machinery to be able to machine both sides the workpiece of different point of view. An electric machinery increases to make tailgate can move up and down below tailgate more convenient operation treatment. Go up commonly trigger of the turn that use formula is as a result of hydraulic pressure system above the machine tool long-term use causes lower mould to bend, because this numerical control bends trigger to install system of a hydraulic pressure in machine tool transfer to a lower level, when fluctuation model works each other this system applies what force reduces lower mould to be out of shape to lower mould, extend the use time of lower mould. Numerical control bends the characteristic of trigger: (After 1) program is built but automatic or semi-automatic job, batch of the workpiece when the process makes treatment finished workpiece to change semi-automatic treatment thereby automatically circularly the inconvenience with big, complex process. (System of 2) numerical control is calculated automatically oil pressure avoids to exceed press pair of machine tools to cause damage. (Of function of input of graph of 3)2D, 3D introduce went to the lavatory the treatment of intricate work, rose to machine efficiency. (The addition of all sorts of 4) device improved treatment technology, reduced the labor intensity that holds the person that do. Be in as Ban gold machinery electric equipment of equipment of traffic of spaceflight, railroad, environmental protection, air conditioning, nicotian machinery, pack presswork, the wide application of a lot of industries such as project machine, spin machinery. Sheet Metal Fabrication also needs more hi-tech workers to undertake operating, good equipment adds outstanding employee ability to make a good product, make there is more and outstanding China to make a product on the world.
