Description
Technical field
The utility model relates to a kind of metal band coiling band head coil-position structure, particularly relates to a kind of asymmetrical positioned curved-surface structure that metal coil tape is taken into volume position impression that reduces.
Background technology
In the metallic plate cold-rolling process of iron and steel and non-ferrous metal strip manufacturing enterprise etc., comprise that the metallic plate behind the cold rolling is smooth, when degreasing, coating, finishing, metallic coil will be carried out the production operations such as batching repeatedly, uncoiling.In the operation process, if uncoiling and batch main shaft and do not use the rubber-like resilient sleeve, then the metal core surface of steel plate of rolling is through the uncoiling of uncoiling main shaft expansion and after batching that main shaft (work) expansion is lower and batching, and can produce tens even the secter pat impression (claiming spool to print) of hundreds of rice and take the lead to impress because bearing taking the lead that larger pressure reflects with the master metal between centers of incompressible deformation; In addition, also can may invar volume core and main shaft frictional force deficiency because of two metal surfaces in running, can not keep good stress condition and the surface that produces combination slides over each other, and cause the wiping scuffing of surfaces of metallic strip.
Uncoiling batch main shaft adopt meet the rubber-like sleeve that operating mode requires material after, generally present higher coefficient of friction because of such material, in certain tensile strength and certain deflection scope, be included in plant equipment and can be provided for providing the main shaft expansion, the sleeve expansion, supporting steel coils, dynamic operations (comprising tension force) etc. are enough, reasonably under the dynamic condition, rubber bush and rotary main shaft and coil of strip can be accomplished synchronous operation, coil of strip and rubber bush can not appear namely, the speed of service of rubber bush and master metal between centers is poor, can not skid, and after the wall thickness of sleeve reaches certain value (generally more than 20 millimeters), the secter pat impression is that the spool seal can be eliminated fully, and the belt end seal of metal tape also has improvement to a certain degree.Skidding in the time of also can overcoming the metal tape uncoiling when adopting 6 sleeves (such as＜20 millimeters) thick than thin-walled caused scuffing to surfaces of metallic strip and avoid skidding.
After unit has configured conventional qualified rubber-like resilient sleeve, although " spool seal " and wiping scuffing problem have obtained solution, belt end seal has also had certain improvement, but the existence of taking the lead to impress just becomes the subject matter that affects the strip quality, do not take special technical measures if do not take for taking the lead to impress quality problems, even if the metal tape of thin specification, such as Automobile Plate or high-grade appliance plate, adopt the oilstone polishing to visually observe check, also have tens or even hundreds of meters take the lead impression; And thick specification, even if do not adopt the oilstone polishing, when visual examination is observed, hundreds of meters the impression of taking the lead is arranged also.A coil of strip for thick specification, in 2 millimeters of thickness, 1200 millimeters of width, as long 1000 meters, then coil of strip heavily has 18 tons, that is to say 18 tons only 1000 meters of coil of strip length, wherein, length with folding line probably just has 200 meters, is waster such as band folding line product, and then its these quality problems just produce 20% bad qualification rate, add other quality problems, total product qualified rate is lower.This is that institute of manufacturing enterprise is unacceptable, also is that market institute is unacceptable.
" a kind of metal coil tape is taken into the volume bit architecture " (patent No. ZL200820154098.6) and " a kind of metal coil tape is taken into volume position adjustable structure " (patent No. ZL20102018146.2) batches taking the lead in the production process at the solution metal tape and obtained world first-class technical indicator aspect the impression.
What patent No. ZL200820154098.6 described is a kind of so nonmetal (rubber-like) sleeve, it processes the constant curved surface of a special setting (the induction part of circumferential position identification upwards is installed in the footpath of this curved surface position) at the outer forming cylinder face of nonmetal sleeve along generatrix direction, after the non-metal kind sleeve is installed in and batches on the main shaft, under the respective signal identification and control of equipment, the position of processing curve will stop the original position of taking the lead of batching to being about to enter, and then enter load operation, make and have the tolerant space of rational curved surface when taking the lead initial batching, nonmetal sleeve is reduced bear take the lead when main shaft harmomegathus, to produce from radially extruding force and take in and take the lead relatively more suitable position, thereby realize reducing a pressure head seal rice number that produces in the metal plate and belt coiling process.
Technology according to patent 200820154098.6 patents can design the sheet material that satisfies the corresponding thickness specification of producing with the sleeve location curved surface of a series of lower different sizes, and its mass effect of eliminating belt end seal all can be guaranteed the complete of downstream user or be satisfied in the main.Patent 200820154098.6 is based on such principle, it is designed locating slot symmetry, the requirement of taking the lead to depart from into volume symmetrical centre is generally ± (15-25) millimeter, 2 distances of R1, R2 and R0 inscribe are between the 50-85 millimeter, and this produces so-called shoulder seal (on start-stop 2 points (line) at this opening) apart from crossing conference at metal tape.
Because the equipment of domestic each cold rolling enterprise is different, also different in order to the Technology Ways that improves the quality of products, even if some unit is designed with and takes the lead positioning function, but owing to having certain difference between the precision that unit working control precision and Operation and Maintenance level and technology itself can realize, even if use the resilient sleeve of similar technology quality, owing to having departed from the control accuracy requirement of setting and can reaching in the patent 200820154098.6, take the lead during actual production into biased from and exceed the control requirement, the product quality indicator of producing just is difficult to guarantee, the quantity that exists of particularly, taking the lead to impress more can not be received by the user.In this case, how to make this class take the lead batching also of unit of positioning accuracy poor (or do not reach designing requirement) and can obtain better quality index, reduce to greatest extent belt end seal rice number, need again original technical realization in-depth and break through the target that the application that Here it is will realize.
