Dispatch of net of machine tool of Chinese numerical control: The gold of the Ban that be not mark with the much need in the production process of the equipment that be not mark treatment, as the ceaseless progress of our country economy and science and technology, and numerical control machine tool is having precision of strong to the adaptability of workpiece remodel, treatment tall, productivity is advanced characteristic; Because technology of this numerical control got applied extensively on Ban gold machine tool, the spare parts precision that it solved the existence in Sheet Metal Fabrication tall, appearance complex, irregular, batch is big wait for a problem, the operation of numerical control system is simple at the same time also greatly the labor intensity that reduced a worker. The gold of the Ban that be not mark with the much need in the production process of the equipment that be not mark treatment, appearance of Ban gold spare parts is not fixed, difficulty of conventional treatment method is great, specific power consumption is tall. Of numerical control technology introduce 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, and have precision of strong to the adaptability of workpiece remodel, treatment tall, raise the characteristic such as productivity, and craft of Sheet Metal Fabrication is developing to diversity direction. The application of numerical control machine tool in Sheet Metal Fabrication can define Ban gold at present for: In the light of metallic thin plate (it is normally under 6mm) craft of a kind of integrated cold working, include to cut, strong / cut / compound, fold a turn, solder, riveting, joining together, shape (like car automobile body) etc. Its striking feature is same part ply agrees. Ban gold generally speaking primary facility includes punching machine of plane shear, numerical control / the machine of cut of efflux of laser, plasma, water, blaze cut machine, machine that fold a turn, and all sorts of auxiliary equipment if: Equal opportunity of uncoiler, school, go burr machine, spot welding machine, machine gnawing a mouth. Ban gold also is made sometimes pull gold, this word originates English Platemetal, it is a few metals thin plate carries handiwork or mould punch makes its produce plasticity to be out of shape commonly, form the appearance of a hope and dimension, can pass further solder or a few machining forms more complex part, the chimney that for instance domestic average uses, iron sheet furnace, still having car case is Ban gold. Normally, 3 step with Ban the most important gold are to cut, strong / cut, fold a turn. Pass in last few years the use of numerical control equipment, can increase in gold of the Ban that be not mark the process capability that go up, resemble plane shear of engine of main cut of efflux of numerical control water, numerical control, numerical control folding curved machine, numerical control to turn at present the equipment such as machine of tower punching machine, spot welding, Plasma Cutting machine can form a product line of complete Sheet Metal Fabrication. At present home uses more shears board, system of the numerical control that fold a turn is like Holand DELEM system, this control system applies relatively mature, stability. 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. 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, 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. The application of numerical control plane shear makes large quantities of quantities repeat next makings to omit underline, to line working procedure, improve labor efficiency, the dimension that assured next makings reachs the public errand of next makings diagonal. Machine of cut of efflux of numerical control water finishs complex form and gold of Ban of starting a hole treatment, machine tool handlers decides according to part drawing and craft requirement treatment program writes a program. Handlers passes the operation face plate of the machine tool to write the program into program memory directly; As microelectronics and computer technology increasingly mature, promoted the development of technology of our country numerical control. As the development of CAD/CAM 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 application of machine of cut of efflux of numerical control water makes originally sophisticated shape structure treatment becomes simple, the treatment of poriferous spare parts locates cut shapes, cut precision is as high as ± 0. 1mm. Folding a turn is Sheet Metal Fabrication shapes medium working procedure, when material bends outer get drawing, lining is compressed, with respect to meeting generation break is mixed when the intensity limit that exceeds material when outer tensile stress break off, it is very width of logical choice mould, important to curve the parameter such as value of round horn radius, pressure, dwell time; Traditional hydraulic pressure folds curved machine to be able to depend on manual estimation only each parameter. Numerical control folds curved machine basis to input parameter self-correcting board makings width of cloth, through numerical control system computation folds curved place to need the relevant parameter such as time of pressure, contact, all parameter show go up in screen. Numerical control folds curved machine to reach a machine tool to comprise by device of numerical control device, servo, hydraulic pressure. Servo is by a servo electromotor and servo actuating device are comprised, the fixed position after the machine tool has electric machinery of a servo, leave out of automatic fixed position underline artificially, the process to the line, mould of convention of the angle that fold a turn is in 78 ° - random is adjustable between 180 ° , change with special mould the smallest angle that fold a turn can amount to 30 ° , and assured treatment precision be in ± 0.
5 ° . Pass new-style mould at the same time choose make machine complex curved curved surface to become reality, machine for example a few nonstandard ark of bridge of profiled bar of angle iron, channel, C, cable, custom-built distribution, can make different specifications product according to producing need. The advantage when additionally numerical control folds a turn to be machined in big batch spare parts is more clear, but one-time all programs folding a turn that complete a work, the self-correcting after systematic set locates, fixed position root tuber changes spare parts size automatically according to the program, can reduce the amount of labor that arises because of carrying spare parts place greatly. 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. The application of their aborning increased capacity of Sheet Metal Fabrication greatly, make Ban gold go up in quality, get assuring on crop. Use with what duration charges a machine tool simplified to manufacture technology greatly, reduced handling time to improve manufacturing efficiency, raised the utilization rate of material greatly, reduced manufacturing cost to reduce labor intensity of the worker, will be henceforth the tendency that equipment application develops.
