Contemporary mould makes horizontal on any account, periodic accident depends on the support of many sided technology, basically include the technology design of the mould, affect mould design and the software of production level directly, the equipment that the mould makes, the standardization of each fittings and generalization, till mould design makes the skill standard of project technology personnel,wait for a lot of respect. But the to stretch component respect requirement in be being made with respect to the mould, basically have the development tendency of a few respects, namely more pursuit is efficient, high accuracy, and the flexibility of good economy and product, can combine a gender. Coil bedspring, get together ammoniac fat bedspring all cannot satisfy afore-mentioned requirements. DADCO company makes a technology with nitrogen bedspring of 46 years, contrive a world's top-ranking nitrogen bedspring, than the life of 40%-50% of tower above of common nitrogen bedspring and precision. It is unapproachable that its sexual price is compared. Nitrogen bedspring is a kind of part that has stretch function. It is high-pressured nitrogen hermetic seal inside affirmatory container, outside force passes force plunger lever to compress nitrogen, rely on high-pressured nitrogen to expand when outside force purify the dragoon power with will obtain certain, the state is made in the advanced mould such as Japan, United States, Korea, Germany in already general application, it can improve mould life, simplify mould design. Accordingly, only DADCO nitrogen bedspring can ensure your mould is expressed future carries top show all the time inside several years now. These year come, industrial product is older and older also to the demand of the mould, and original groovy and stretch component is certain defect, cannot satisfy the need of this kind of situation, cannot resolve the demand in punch craft ideally. This kind of circumstance often can affect the quality of stamping workpiece, make mould structure design becomes more complex, affected the time that the mould changes on compressor; The mould space that with constant compasses flexibility component has is too large, increased the cost that the mould makes. For example coil bedspring, get together ammoniac fat bedspring all is existing to need to be tightened beforehand, ability achieves the dragoon power that designs a demand, and their dragoon force is be increased along with the journey and increase apparently, this kind plays the function with not constant pressure, the likelihood causes a part cannot figuration, delaying pressure to pulling is very unfavorable. Be like coil bedspring again, get together the initiative power of ammoniac fat bedspring is not great, this initiative to the requirement power is greater bend, the craft such as flange, not ideal also. The result that produces from this is, punch is made quality is not stable, adjust mould take time arduous. To concentrated model of drift strong dismiss technology, if use coil spring, get together discharge of ammoniac fat bedspring, the discharge space that often can encounter a mould puts coil spring not quite, get together ammoniac fat bedspring, consequently need increases mould space to solve this kind of problem. OK still adduce this kind of many example. For this, people develops a kind of new-style stretch function component to replace groovy stretch component hard, complete the work that groovy and stretch component is hard to complete, nitrogen bedspring as component of new-style and stretch function also with respect to emerge as the times require. It can serve as independent component, installation is used in the mould, also can design bedspring of nitrogen of type of a kind of tube bank, the one part that serves as a mould has a job, can be in the system force of dragoon of very convenient implementation is constant with delay time movement, it is one kind is had flexible the flexible assembly of function. Nitrogen bedspring can be not only in mould industry wide application, also can use other industry field, if record the trade such as model, car, electron, appearance. Be in China, DADCO nitrogen bedspring appears with the attitude of product of a kind of new and high science and technology, whether can have an insight into first machine general becomes extensive pattern manufacturer to be in market tide a magic weapon of get the upper hand of. The structural design of nitrogen crock, sealed technology is the crucial technology of assess of nitrogen bedspring quality. Current, nitrogen bedspring makes a technology precede most with American DADCO, 60% what hold global sale, than tower above of general nitrogen bedspring the life of 50% , can achieve annual 1 million dragoon. The structure of nitrogen bedspring is type of single accent force plunger. The production of nitrogen bedspring is a kind integrated the product that each new technology uses. It is sealed and difficult that gas of long-term and sealed high pressure should compare a liquid much, this has sealed configuration among them, static sealed with use sealed method, form, the choice of technology of surface roughness of the production nicety of crock wall, surface, finishing, sealed material, sealed dependability and life. The characteristic of nitrogen bedspring is to be in lesser space, can produce greater initiative dragoon power, do not need to be tightened beforehand, the module that send force has dragoon power with contact of nitrogen bedspring force plunger at the beginning. Bedspring of a nitrogen can replace many common bedspring, to the pattern with working same route, the mould height that uses the mould height of nitrogen bedspring to want commonner than using spring is a lot of smaller; Dragoon force is in whole journey, can keep basically constant; Press working procedure to ask according to different Leng Chong, its play the size of pressure, the position of dot getting power is OK at any time accurate, convenient adjustment, in the mould is designed and be debugged, can force of dragoon of very convenient implementation and balance; Simplify the structure such as mould pressure, discharge, simplify mould design, shorten the mould makes cycle; Improve stamping workpiece quality, assure to rush make a quality stability, shorten change on compressor mould time, improve labor productivity, reduce cost, tool set definition is high; Service life is long, safe, honest, installation and maintenance are simple, reliable, convenient. The first when in mould design bedspring of choice application nitrogen should notice problem that encounter plays the option of pressure namely, choose the nitrogen bedspring of what form, the nitrogen spring that chooses much great power will satisfy the requirement of punch craft, solve such problem, normally need considers size of force of nitrogen bedspring dragoon; The amount of nitrogen bedspring; The pressure boost of nitrogen bedspring is compared. The journey of nitrogen bedspring should satisfy the requirement of punch craft, different punch process, the journey measurement of the requirement is different. Strong reduce separate process, requirement dragoon muscularity, journey is small; Pull delay working procedure to ask the distance is greater commonly, regard the nitrogen that controls edge force function as bedspring, ask its character curve is gentlier, in pull in extending a process, the force that approach a limit basically changes not quite, play pressure to keep basically constant namely; Go out to the top, discharge, that has enough power and stroke with respect to the requirement; Be in bend and in flange craft, ask normally initiative muscularity, so that can pin workpiece, prevent workpiece to produce sideslip or shift in curving a process, say the journey to also ask to compare commonly big. No matter which kind of circumstances, the total height of nitrogen bedspring does not want too tall, produce not stable phenomenon in order to avoid, when avoiding nitrogen bedspring to be installed on the mould, the structure is too complex, raise tool cost, if nitrogen bedspring installation is inside upper mould, no matter be a top board or it is the circle that approach a limit, must stay have space, in order to ensure nitrogen bedspring works smoothly; For safe for the purpose of, the situation that prevents an accident happens, personnel of design of proposal of DADCO nitrogen bedspring returns Lv of take an examination to increase safe journey when choosing nitrogen bedspring (install total travel to should be piston column journey commonly 10% ) , make sure nitrogen works normally for a long time thereby. Divide this beyond, return the alternative that should note nitrogen bedspring configuration, it is with bedspring of American DADCO nitrogen exemple can divide join for type of seat of bedspring of bedspring of independent type nitrogen, nitrogen, pipeline type a few kinds. These basic configuration have respective characteristic and certain applied limits, the cost of requirement of environment of the configuration that needs the punch craft requirement according to the spare parts, mould, use equipment, work, work, mould and adjust maintenance to go to the lavatory wait for an element, consider integratedly to choose. Additional, also want to choose nitrogen bedspring in the light of diverse demand in design of cold punch mould. Same dragoon power, use the nitrogen bedspring with constant force to want to compare force not constant expensive, the nitrogen bedspring journey of same norms grows more expensive more. Accordingly, want to ask according to different technology, choose different nitrogen characteristic curve, obtain first-rate sex price and first-class economic benefits thereby. Play pressure in mould design deliver ought to poise, bedspring of choice application nitrogen often more than, so, exert oneself nods decorate wait to need around solve problem of a balance, say from punch craft angle, also be the issue that needs to consider punch to balance, with benefit the service life at raising a pattern, assure the quality of punch spare parts. Be informed from the use of DADCO nitrogen bedspring of the United States, nitrogen bedspring is to be the same as a spare parts to produce a contact directly, it is the tip that passes a design board, very piece, the circle that approach a limit, inclined wedge piece wait for mould spare parts to transfer dragoon power mould job part, so very board the motion that waits for mould work spare parts is balanced, decorate with what force fastens about; Support on the other hand board also be the effect that has to deliver force to give nitrogen bedspring, carry to avoid generation nitrogen bedspring to slant accordingly, raise nitrogen spring slant carry bear force, assure the service life of nitrogen bedspring, should using nitrogen bedspring pressure is the design method of center and coincide of photograph of punching power center. No matter nitrogen bedspring is in when installation or it is the stability that needs to comparative when the job and dependability, comparativing because of its dragoon force big, bedspring of a nitrogen is inside not large volume, should release hundreds of kilograms even a few tons force, and this process is undertaking ceaselessly repeatedly, accordingly, what the stability that maintains its to work comparatives is important, make measure bigger nitrogen bedspring forcibly especially, must want to ensure firm, return buy nitrogen spring especially or be installation in upper mould, nitrogen bedspring needs ceaseless along with the motion of slide block opposite exercise, only firm join ability assures the work with nitrogen normal, steady bedspring. When often designing installation nitrogen bedspring accordingly, or in cylinder body or the installation heavy opening that has certain depth is offerred in force plunger, in order to ensure its, avoid to happen deflective. The working quality that ought to say nitrogen spring is to belong to flexible category, in mould job process, open and closing ought to be to compare smooth-going, ought not to appear concussion phenomenon, to achieve this goal, to using spring of independence type nitrogen, design personnel wants mature to this. Narrate because of the place before be like, the frequency of nitrogen bedspring is very tall accordingly, once the spare parts contacts lever of nitrogen bedspring force plunger to be able to produce dragoon power, need to have the process that tightens beforehand far from, so as compressor slide block go up, next motion, nitrogen bedspring open (expand) and close (compress) answering is very fast, if the design is undeserved, use nitrogen spring on small tonnage compressor especially, with respect to possible meeting occurrence nitrogen bedspring is driven slide the phenomenon of a return trip, destroyed the curve that brace compressor slide block moves, bring about appear shake concussion phenomenon. Accordingly, ought to avoid to appear as far as possible this kind of phenomenon. Whole world mould is made forward the way of nicety, complex, efficient, macrobian life develops quickly, the die manufacturer of hope home can make full use of abroad's advanced technology and product, make the world top-ranking pattern that belongs to ourselves.
