Big machine tool of half basketball field is in Wuhan ” premiere ” , nonlocal machine tool opens first 4S store in Hubei. Can go up in the machine rich that kicked off on September 23, numerous ginseng exhibits an enterprise to all express the strong interest of pair of Hubei cars and component industry, in succession layout Wuhan market. Shenyang machine tool monarchs 23 days only the biggest exhibit, show equipment of machine tool of on 10 large high end. Among them value is controlled 3 million yuan, cover an area of size of half basketball field ” horizontal machining center ” , use technically at component of sophisticated car, shipping, aerospace one-time processing. In addition, 1 million also have 34 to 2 million yuan machine tool. By factory of Shenyang machine tool of own research and development ” vertical machining center of 5 axes linkage ” also be in Wuhan ” premiere ” , according to agential Hubei Zhang Jun of president of trading company of 3 annulus whole set introduces, price of this tall accurate machine tool 1.8 million yuan, already was close to international banner level, precision amounts to 0.001 millimeter. “So luxurious battle array is to be in Wuhan to appear first. ” Zhang Jun expresses, inn of 4S of machine tool of Hubei head home already built in Wuhan this year, product of machine tool of main representative Shenyang. This year in September, be aimed at technically still have those who buy large facility need is medium small look forward to, roll out a machine tool to mortgage loan business. Zhang Jun says frankly, because dimensions of this enterprise of province car component is lesser, although dragon of east wind, god is truckload,the factory all is set in Hubei, but 80% component from provincial purchase, if enterprise of this locality component throws a product line to need 30 million yuan at least, medium and small businesses lends a money very hard from the bank. To solve this one problem, roll out machine tool equipment to mortgage business especially. At present Dun mouth developing zone has two companies, 10 lasher also have enterprise of a component to reach instalment to purchase intent. Before Japan is ranked 3 mechanical agent — the trading company also reachs hill kind first Chinese, be used at processing product of communication of car component, photoelectricity showpiece ” machining center ” , stick piece ” extend meeting special offer 430 thousand yuan ” . Appearance of equestrian field filial piety shows president of division of China of hill be apt to, this year in July, just was in Chinese establish this enterprise to be in first mid office. Introduce Japanese mechanical and electrical products Wuhan, value Hubei automobile industry to develop just about, there is thorough collaboration with this cropland in Japan, but to China as Japanese car manufacturer mid city is transferred, of mechanical trafficker ” form a complete set ” also enter subsequently Chinese, at present already with east wind this cropland undertook a butt joint.
Recently, the bureau of industry of national defence science and technology that spaceflight assumes 303 times (division of former national defence is versed in appoint) metric task ” technology of calibration of precision of geometry of space of numerical control machine tool ” passed a test to evaluate. Current, this task has prepared all checking and accept data, plan to report bureau of work of national defence family to check and accept evaluation. This task uses much general to strap laser interferometer logarithm to accuse diagonal of machine tool body to undertake metrical, use the pace that divide an axis to advance the principle of the law, through compensating the research of the principle to error of space of numerical control machine tool, make up dimensional error to compensate software and interface communication software oneself, compensate a model through built dimensional error, depart gives the 12 errors weight of numerical control machine tool, compensate a watch from error of movable unripe space, pass interface communication software, keep watch of dimensional error compensation into numerical control machine tool, realized the compensation of precision of geometry of space of numerical control machine tool, and compensation effect is apparent. With the pitch error with numerical control at present general machine tool compensation means photograph is compared, this technology achieved a big breakthrough.
Limited company of machine tool of Changchun numerical control is a business that pursues a machine tool making for years, main production general accuracy machine tool, friction welding receives machine tool and digital machine tool 3 kinds of products. From 2008 second half of the year begins, foreign order decreases, company profit exceeds now to slip. Face stagnant economic situation, this company captures its friction welding to receive technical divisions to precede at international level this one advantage, increase ” Changchun numerical control ” the productivity that friction welding receives a machine tool, benefit servantchooses a person for a job to make a brand without technology of my some core, enter the market. Authority of Jiang Hong of company chief engineer expresses, company the order Feburary does not fall to be added instead, had achieved 8. The business that strengthens own brand construction so like Changchun numerical control still has a lot of. Surpass in 100 grams, gold, amend, the enterprise such as technology of new industry photoelectricity, project controller is in in speaking of financial crisis ” go against the raise on situation ” when the reason, happen to coincide the ground mentions the value that the brand builds.
Reciprocating type odd screw mixes refine extruder is one of common plastic and mechanical equipment. In the treatment process of any polymer. Gift the fabricating characteristics with certain polymer or gift products is specific performance characteristics. Often need to undertake different polymer between be mixed in all or polymer is the same as the mixture between all sorts of auxiliary, dye. Overcome colophony of the partial gel grain that the possibility between its element produces or end melt. And puissant blender has odd screw of plastic and mechanical reciprocating type fitly cut the even, expensive dispersive, expensive stuff, characteristic such as drawing fuse-element. And integrated the advantage of extruder of odd, double screw. Unique working principle, the whorl that adds on one cycle sets component and facility of form a complete set, make its application wider, on a machine, can accomplish batch mixing, mix refine, model to change, dispersive, cut, drawing, take off gas, build bead, make the interfacial area that fuse-element flows in the machine far large flow at be being cut commonly.
Odd screw of plastic and mechanical reciprocating type mixes the structure of refine extruder and utility to be as follows:
1, leader plane canister, screw all uses building blocks type to assemble. Machine canister is comprised by much group starting a hole and closed pore cylindrical shell, analyse divides the cylindrical shell of type, can open expediently quickly, facilitate clean, overhaul; screw by cover all sorts of snail mixing refine on core axis piece and carry snail piece composition. Machine canister and screw can differ according to stock breed, what craft asks is different, comprise good form neatly.
2, gear case and sway box is designed distinctive, came true while screw is doing whirligig, undertake the reciprocate of axial, screw every turn a week, reciprocate, whorl is interrupted 3 times, produce the strong result that mix refine thereby. Its mix action is in axial is not in radial, and happen between whorl and pin. Total stock gets inside snail chamfer even shearing stress, the stock that is not one layer is cut.
3, the permutation of type of whorl cell building blocks is on core axis, can undertake permutation assorted according to diverse demand. Machine cover liner go up how to contain 3 pin, pin cent is 6 kinds of model, sincere grows pin to use fixed liner to cover, enhancing; of the effect that mix refine to grow pin action hollowly is fixed, mix refine, installation to measure lukewarm head, long pin of crop of; of inject liquid auxiliary secures liner to cover; crop pin to be used jam reserve pin of short sincere of refine action; is mixed to undertake to taking makings mouth stock since pin of aperture; sincere broken.
As the reciprocate of screw, the opposite motion contrail of pin and every snail piece shows a curve, produce axial stock exchange when mediate pin passes whorl space, pin is in the process of screw circumgyrate circuit, produced pair of stock with the opposite motion of snail shuttle side cut pair of screw and machine canister to undertake clearing in axial and radial. This is reciprocating type mixes refine extruder to mix thoroughly, foundation of action of mediate He Zijie. These pin are like the beater of same set, make stock realizes redistribution, discontinuous whorl makes stock produces circumfluence, make stock bears to be cut continuously, the process of orientaton, cut, fold, drawing.
One part fuse-element is united in wedlock afresh, one part fuse-element goes further break up, in the snail chamfer of every L/D, fuse-element wants to be broken up through 4, from this knowable, why can reciprocating type extruder be Bineishi mixes very short long way effectively of fuse-element now. And the surface inside machine canister by whorl yuan make sweep anything away pass, shed blind angle without content, have very good from clean ability, taller transportation efficiency and stable and even stock retention period.
4, fuse-element is, action is the discharge after the pressure boost of fuse-element of high temperature polymer that will come from extruder, Qing Dynasty is pressed send crowded head giving a model steadily. No matter how force of extruder internal pressure changes, how does discharge fluctuate, fuse-element pump can furnish from beginning to end the stock that modular head measures certainly. Gear is the core of fuse-element pump, the whirl of gear and respect of to bite syncretic can squash tine) the fuse-element between I, make stock carries another ground; from one aspect of the matter on the other hand the clench the teeth of gear can close low-pressure antrum, decrease to drop treatment temperature upstream, be helpful for building higher output pressure. We use involute helical gear, can increase the registration of gear clench the teeth, when clench the teeth as gear ceaseless inspiratory can undertake add, smooth extruding to stock with eduction, reduce the wave motion of pressure, achieve stability to carry the end of fuse-element. At the same time helical gear still is had certain from clean action, avoid the deposit of stock to decompose.
In fuse-element pump exterior of heat, cooling device, the purpose is control temperature inside certain limits, make its hold first-rate craft position, heat means has report to heat with oil two kinds of forms. Additional, the working principle that reciprocating type odd screw mixes refine crowded airplane and character decide this machine is used at plastic processing to be not its director, but, match after extruder with fuse-element pump, shape together modular head join, combine the modified that mix refine and processing the 2 brand-new technology that are an organic whole, decreased to build a link, mean reduce investment, reduce manufacturing cost, shorten production is periodic, saved the sources of energy, the hot course that fuse-element omited fabricating model is changed, the advanced sex of this one technology and economy are self-evident. Fuse-element pump jacket has a group of pressure sensor, measure an its pressure change well and truly, be helpful for the adjustment of craft.
5, accurate metric. , way of logical feed in raw material is the key that carries out a recipe strictly, also be assure product quality the first close, we the function according to stock, the need of the user, deserve to have a variety of feeding stuff kind, if volumenometer quantity, dynamic weightlessness is metric,wait a moment, in order to satisfy the need of different product.
6, the system deserves to have screw of compulsive feed in raw material, side direction double screw is fed makings, preventive makings piles up in mouth of feed in raw material, expect in order to make sure each constituent stock is entered in proportion at the same time, solved the environment that creates as a result of premix to pollute a problem.
7, this machine uses device of Xi Menzi frequency control, function is admirable, reliable. Cylindrical shell uses report to add hot water to cool, deserve to have 2 class pressure sensor, intelligence of 6 groups of RKC charge lukewarm unit, two-way PID adjusts, the frit temperature inside canister of quadruplet development machine spends sensor. Bona fide reflects the actual temperature of each area fuse-element, additional, have appearance of check of make one’s rounds of a many dot temperature, so this equipment accuses Wen Zhun truly, the error is small. Interlock of advanced machinery, electric equipment, have machinery and electric equipment double overload protection, can protect equipment and person security effectively, imitate is set to show drawing board on ark of device control character, circumstance of each place roll shows set intuitionistic and clear.
8, the system deserves to the water-cooling that pull silk cuts bead, eager water-cooling, eager wind is cold wait for a few kinds of means that cut bead. Can differ according to material, the requirement of the user undertakes configuration.
9, the system deserves to pair of rank type create an unit, use equidistant waiting for extruder of deep odd screw to carry fuse-element action is the model that finish change and fore-and-aft mix, those who build stability is crowded give pressure, because its rotate speed is inferior. Cut consequently inferior, avoid stock to produce advocate cut heat, accuse lukewarm optimal.
Such configuration to a few low product of sex of epispastic, heat quick will tell, the system will be mixed refine and build pressure two paces craft is handled apart, turn fuse-element model hand in after finishing constant pressure, send crowded head giving a model lukewarmly, mensurably to cut bead surely, prevent to heat up quick sex and the degradation that cut quick sex stock, have yield tall, produce character to measure stable characteristic, the process that mix refine can be optimized do not suffer create makings craft effect. In the process that enters odd screw in stock, set vacuum exhaust, exhaust of this kind of method because exhaust area is large, change of stock watch area is big, have sufficient exhaust time, compare exhaust of extruder of sheet rank exhaust to change so fruit is good.
10, in leader plane canister jacket has hopper of evacuating device and automatic exhaust, compulsive feed in raw material to go up, automatic exhaust all is set on side direction feed in raw material, all sorts of volatilization of the generation in the water portion in excluding stock in order to assure thoroughly and treatment process gas.
