High accuracy cold attracted precision tube is really a new kind of high-tech energy-saving items. In modern times, the utilization of this technology within the production associated with precision metal tube may be widely utilized in domestic hydraulic, pneumatic canister, coal my own bracket (pillar), essential oil pump tube, jack along with other manufacturing places. Application associated with high accuracy cold attracted precision metal tube in order to save steel, enhance the machining effectiveness, save power and slow up the hydraulic canister, cylinder digesting equipment expense has essential significance.
Chilly drawn technique: production associated with high accuracy cold attracted precision tube in contrast to traditional reducing technology, the hydraulic cylinder has got the following features:
(1) higher efficiency: with the standard method to make a 420 mm internal diameter, 12 yards long cylinder ought to be 154 several hours, with chilly drawn technique production just 4 min’s.
(two) higher functions: because of the effect associated with rolling stress head and also the guide from the boring, along the way of reducing, the empty pipe because of the weight from the deflection, the actual rolling mind deviate as well as boring used vinyl cutter, cause waste materials. Functions just around 60%, with cold attracted method manufacturing, functions may reach a lot more than 95%.
(3) higher utilization price of steel: made associated with traditional approach to boring canister body, steel utilization just 50-70%. When utilizing a approach to drawing manufacturing, metal not just by cutting the finish of the actual iron, it may get 30% expansion of steel utilization price can achieve 95%.
(four) can enhance the mechanical properties from the finished pipe metal: manufacturing by sketching method, make empty gets a lot more than 30% from the plastic deformation, due to operate hardening offers greatly improve the effectiveness of the completed tube steel limit. Generally within the finished pipe layer power limit improve of 60%. High accuracy cold attracted pipe consists of seamless hot-rolled metal pipe, directly seam welded tube as empty, after chemical substance treatment about the special chilly drawing device, through the actual special deformation theory of style of mildew drawing, create high accuracy tube. The actual dimensional precision of H10 ~ H8, straightness associated with 0. thirty-five ~ 0. 5 mm/m, the top roughness Ra1. 6-0. four.
Production process is really as follows: give food to, appearance examination, mechanical cleansing, mechanical cleansing, annealing, styling, tube digesting, pickling, neutralizing — water — scale alter – saponification — drawing — check — cut in order to length, honing, finish processing, styling, assembly, screening, packing
Higher precision chilly drawn accuracy pipe software:
(1) architectural hydraulic equipment, such because hydraulic pickup truck crane, excavator, bulldozer, forklift, and so on.
(two) within the coal my own hydraulic assistance: at existing the nationwide production offers 48 downhole hydraulic support from the enterprise, the actual high accuracy cold attracted pipe, the entire demand around 1. two million yards.
(3) hydropower train station gate crane device, template, especially within the Yangtze water three gorges project is really a big demand within the next decade.
(four) building machinery: the job high over the raising machinery, general creating construction repair can also be inseparable in the hydraulic equipment. oil geology tube
(5): oil fields from coast to coast each year have to pump a lot more than 30000 models, annual usage and higher precision tube a lot more than 20-40 yards, also may use this technologies finishing a myriad of drill tube.
(6) hands industry: army departments right now use weapons tube re-writing method digesting, spinning technique is reduced productivity as well as high price, production is appropriate in chilly drawing method.
(7) showing industry: presently, the production from the rolling showing race, along with round metal as uncooked material, the actual slice via stamping. Large showing race is going to be hollowed to create solid club, metal usage rate of under 40%, an urgent have to high-precision, showing steel heavy wall tube. Drive base, automobile business
(8): 95 6000 a lot of precision pipe, axle pipe 10000 lots and a number of pipeline, and so on.
(9) aviation business: aluminum metal aircraft getting gear as well as thick walls steel tube, etc.
(10) jack port: jack production in The far east has substantial strength, good potential customers to earn foreign currency through exports. Our manufacturing enterprises at the moment several thousand catties Ding Gang utilizing solid club processing, reduced production effectiveness, high materials waste, immediate demand with regard to high accuracy cold attracted pipe.
(11) the areas: all types of printing roller, roller roller pipe, stainless metal pipe, light weight aluminum pipe, copper mineral pipe, special pipe and also the inner as well as outer pipe Article Distribution, and the like can be made by this technologies.
