Background technology
China is big steel country, but also is not iron and steel power.In the common iron surplus, the wide cut of high rigidity material (as stainless steel, silicon steel etc.), high accuracy size, high-quality template shape, as thin as a wafer (≤0.15mm) cold-reduced sheet still needs import.Produce high rigidity, the whole imports of high accuracy cold-rolling mill of this series products.In the non-ferrous metal field, be used for the rolling wide cut Copper Foil (cold-rolling mill of thickness≤0.05mm), and the small-sized ultraprecise stiff mill that is used for superhard materials such as rolling titanium, titanium alloy, tungsten, molybdenum does not still have off-the-shelf equipment and can use.At present international existing 20 cold mills such as ZR milling train, 4 column milling trains and hybrid milling train are by being installed in the camber that another set of tooth bar eccentric adjusting mechanism on two backing cloth bearing rollers in top (or sidepiece) regulates backing cloth bearing roller, realization is regulated control to the plate shape of rolled piece, has brought following point:
The requirement of (1) two cover tooth bar eccentric adjusting mechanism installing space, the interval between the adjacent back lining bearing is strengthened, and makes the stressed increase on the axial unit length of back lining bearing, and promptly bearing load strengthens.
(2) interval between the back lining bearing is strengthened, and the discontinuity degree axial to second intermediate calender rolls strengthens, reduce by two in the middle of roll shaft service life.
(3) back lining bearing roller core shaft cylindrical contacts with the saddle inner ring through two-layer eccentric bushing, and the saddle inner ring diameter has to strengthen, and the saddle outer ring must be less than the back lining bearing external diameter.Like this, two-layer eccentric bushing and saddle all are thin-walled parts, and machining deformation is difficult to control.
(4) and complex structure, can not effectively carry out convexity fine tuning, cause rolling thin plate quality product rate low driving backing cloth bearing roller, less than 30% usually, production efficiency is low.
Summary of the invention
The purpose of this utility model is a kind of cold-rolling mill hydraulic direct drive backing cloth bearing roller convexity fine tuning structure of design, can overcome the deficiency of existing cold-rolling mill convexity fine tuning structure, has reasonable in design, having the backing cloth bearing roller of making can finely tune by segmentation hydraulic pressure, to realize high precision rolling, the advantage that transverse gage sum of errors plate shape is effectively controlled.For this reason, the utility model adopts in cold-rolling mill roller system on two in outer end, the last left and right sides and is provided with backing cloth bearing roller convexity fine tuning structure between the backing cloth bearing roller and whole frame.Described backing cloth bearing roller convexity fine tuning structure is by the backing cloth bearing roller piston seat, the hydraulic pressure stationary cylinder, piston packing ring, hydraulic pressure chamber, hydraulic circuit and elasticity bolt constitute, go up the back lining bearing roll shaft admittedly on backing cloth bearing roller piston seat separately for two of outer end, the last left and right sides, be connected with elasticity bolt elasticity between backing cloth bearing roller piston rear end and the whole frame, recessed hydraulic pressure chamber is set at backing cloth bearing roller piston rear end middle part, corresponding with hydraulic pressure chamber whole frame is provided with the sliding hydraulic pressure stationary cylinder that fits in the hydraulic pressure chamber, piston packing ring is between the hydraulic pressure stationary cylinder and backing cloth bearing roller piston seat of periphery, the hydraulic circuit front end hydraulic pressure chamber that communicates, the hydraulic circuit of every pair of symmetrical hydraulic pressure stationary cylinder is by with 1 hydraulic servo control valve control.Said structure has reached the purpose of this utility model.
The utility model has the advantages that the deficiency that can overcome existing cold-rolling mill convexity fine tuning structure, has reasonable in design, having the backing cloth bearing roller of making can finely tune by segmentation hydraulic pressure, to realize high precision rolling, the advantage that transverse gage sum of errors plate shape is effectively controlled.The present invention reaches more than 98% rolling thin plate quality product rate, has improved production efficiency greatly.
