Description
Technical field
The utility model relates to a kind of novel roll gap adjustable flattening machine, particularly relate to a kind of for improving cut deal plate shape, roller number is variable, limit roll spacing is adjustable, backing roll row is many, and can realize the roll gap adjustable flattening machine of fast roll changing.
Background technology
Straightener is one of main finishing equipment on Heavy Plate Production line, for straightening steel plate, makes its glacing flatness meet national standard and client's requirement.In order to improve plate shape, improve the quality of products, modern straightener has adopted multiple technologies and means.
The aligning process of steel plate is exactly repeatedly to bend and the process of spring-go, after the press-bending and spring-go of several times, the glacing flatness of steel plate will reach the requirement of standard, because thickness and the original curved of every block plate are not quite similar, so the press-bending number of times of demand and press-bending degree are not identical yet, can realize every smoothing roll of participation work to the press-bending degree of steel plate by multi-form aligning roll gap is set.For the setting of aligning roll gap, what generally use at present is that upper roller system entirety is depressed, then by upper roller system along rolling line direction and vertical rolling line direction fascinate realize; Part straightener is designed with upper roller system cambering roll function, before every block plate aligning, certain roller amount is set, to compensate the strain of roll gap in aligning process or to eliminate certain bilateral wave and middle unrestrained defect according to knowhow in the past; But to upper roller system roller, and pre-bending before aligning, can not adjust, online so practical effect is unsatisfactory due to only.
The steel plate specification limit of Heavy Plate Production is wider, the aligning scope of straightener is difficult to meet the demands simultaneously at present, for aligning roll gap that various ways is set is more flexibly to adapt to the steel plate specification of wide region, SMS-SIEMAG company of Germany has released nine-five roller cold straighteners in recent years, nine rollers or the five roller participation work that are by converting same set of roller, can effectively improve steel plate and steel-sheet aligning scope, only have the new cold straightener of going into operation of several families such as Yingkou 5m, Baosteel 5m to adopt this structure at China at present.But such straightener using is at present in the process of variation roller quantity, the distance between roller cannot change, and the scope of straightening steel plate is had to certain restriction.In the time of multi-roll straightening machine aligning thick steel plates, can realize by the smoothing roll quantity that reduces participation work, but in reducing smoothing roll quantity, there will be the inhomogeneous situation of spacing, nine-five-roll machine of for example this version is in the time using as 5 roller straighteners, limit roller roll spacing is much smaller than other roll spacing, and this makes in the time of aligning slab to the press-bending degree of steel plate not or the undercapacity of limit portion smoothing roll, limited the scope of aligning slab on largely; Passage can only be aligned by increase in the time of aligning slab by the producer of this structure type straightener of certain applications now, just can make the glacing flatness of steel plate reach the requirement of standard.For the larger straightener of straightening steel plate specifications vary, only rest on theory stage, propose can practice change roll spacing structure.
In addition, adopt of the smoothing roll of existing straightener divided work or transmission separately more, by spline transmitting torque; When roll change, old roller is that its smoothing roll spline tooth is deviate from from universal-joint spindle splined sleeve by changing rig pull-out memorial archway; In the time that new roller system pushes, easily cause each spline tooth not mate with the position of splined sleeve, cause new roller system directly accurately not insert, extend roll changing time, reduce production efficiency.Existing part straightener has configured the special tool(s) designing for fast roll changing, as pair roller spline template, but these operations also need to spend a large amount of human assistance time, and need to guarantee that the rear all smoothing rolls of old roller system's extraction can not have the rotation of any angle, otherwise pair roller spline template will arrange wrong initial angle for new roller system smoothing roll spline tooth, can delay on the contrary more roll changing time.
Because the above-mentioned problems of existing straightener, the design people is based on being engaged in Machine Design manufacture rich experiences and excessively strong professional knowledge for many years, in conjunction with the application reality of plate leveler, actively research and innovation in addition, to overcome the shortcoming of prior art in structure aspects, provide that a kind of roller number is variable, limit roll spacing is adjustable, roll change rapidly, maintenance convenience, compact conformation, roll gap adjustable flattening machine that production efficiency is high.
