Abstract
The utility model provides a roller control device of a rolling mill. The utility model is characterized in that the upper part of an upper roller and the lower part of a lower roller are respectively provided with a bearing wheel group, and each bearing wheel is connected with a hydraulic cylinder. The utility model can control the pressure force of the corresponding hydraulic cylinder according to requirements in the proper time to balance the pressure force of the rollers, which is applied by the bearing wheels; therefore, the defects that the uneven thickness of steel plates is caused by the integral bending deformation of the rollers, the cross sections of the steel plates are easy to become a waist drum shape with thick middle and thin edges or a concave shape with thin middle and thick edges, etc. are fundamentally eliminated; the thickness of the rolled steel plates always keep consistent, and the quality of products is further improved; the arrangement of the other bearing wheel group can not affect the surface of each of the rollers. The utility model has the advantages of high response speed of the hydraulic cylinder, high control precision, high stability simple operation, etc. The utility model is an ideal roller of a rolling mill.
Description
Technical field
The utility model relates to a kind of control device of rolling mill roll, especially a kind of roller controller of cold-rolling mill.
Background technology
Double-roll rolling mill ubiquity following point: the one, the surface elasticity problem on deformation of roll, the 2nd, the integral, flexible flexural deformation problem of roll.The elastic bending deflection of roll integral body will directly affect the transverse shape of steel plate, it can make, and the cross section of steel plate is that the edge is thick, intermediate thin dolioform.This dolioform steel plate is little to the steel plate influence, but then can produce tangible influence to sheet metal or iron sheet etc., even can reduce the serviceability of product quality and product.People did following improvement for this reason: the one, change double-roll rolling mill into four-high mill or multi-roll mill, and plate quality is obviously increased, dolioform cross section also is greatly improved; The 2nd, with the shape of roll itself by cylindrical change into dolioform, thereby the transverse shape of the steel plate that rolls out is made moderate progress, but this roll is more inflexible, can't control at any time as required, especially when the Strength Changes of steel plate, shut out the steel plate cross section of coming with this roll and still can change, even can shut out spill steel plate (that is: the steel plate of thick, the intermediate thin in both sides).But above-mentioned all improvement all do not tackle the problem at its root.Because the bearing capacity of existing roll is all at the two ends of roll, strain takes place this also is inevitable in roll in the operation of rolling like this, Here it is place at all.Therefore, be necessary fully prior art is improved.
Summary of the invention
For overcoming existing roll because of the quality problems such as product distortion that strain is brought take place, the utility model provides a kind of rolling mill roll control device that can keep each stressed place equilibrium in the rolled plate process.
The utility model is realized by following technical proposal: a kind of rolling mill roll control device, it is characterized in that above the topping roll and bottom roll below be respectively equipped with the carrying wheels, and each bearing wheels all links to each other with hydraulic cylinder.By the pressure of the corresponding hydraulic cylinder of control (increase or reduce), eliminate the distortion of roll integrally bending, thereby make the steel plate thickness that rolls out remain unanimity.
The carrying wheels of described topping roll top and the carrying wheels of bottom roll below are symmetrical arranged or asymmetric setting, so that come the corresponding bearing wheels of balance to give the roll applied pressure by the pressure that changes each hydraulic cylinder, thereby the roll-force at each position of balanced roll, guarantee rolling steel plate transverse shape constant, improve plate quality.
The surface of described each bearing wheels adds nylon jacket, is used to prevent that bearing wheels breaker roll surface from causing excessive pressure and the distortion that produces.
The wheel face material selection hardness of described each bearing wheels is lower than the material of roller surface hardness, is used to prevent that bearing wheels breaker roll surface from causing excessive pressure and the distortion that produces.
The utility model compared with prior art has following advantage and effect: after adopting such scheme, can control the pressure of corresponding hydraulic cylinder as required in good time, with each bearing wheels breaker roll applied pressure of balance, fundamentally eliminated the steel plate uneven thickness that brings because of the distortion of roll integrally bending, easily make its cross section thick middle occur, dolioform or the intermediate thin of thin edge, the deficiencies such as spill that the edge is thick, make the steel plate thickness that rolls out remain unanimity, further improved product quality, the setting that other carries wheels can not impact on the breaker roll surface, the response speed of hydraulic cylinder is fast, the control accuracy height, good stability, simple to operate or the like, be a desirable rolling mill roll in fact.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Specific embodiment
Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.
As figure, topping roll 1 is symmetrical arranged with bottom roll 2, be used for steel plate is rolled, above the topping roll 1 and bottom roll 2 below be arranged with the carrying wheels 3, each bearing wheels surface is provided with nylon jacket 4, and with the influence that prevents that bearing wheels breaker roll surface from causing, each bearing wheels links to each other with plunger-type cylinder 6 by support 5, the pressure size of control hydraulic cylinder 6 can balance bearing wheels 3 breaker rolls 1,2 applied pressures.
Claims (4)
1, a kind of rolling mill roll control device, it is characterized in that above the topping roll and bottom roll below be respectively equipped with the carrying wheels, and each bearing wheels all links to each other with hydraulic cylinder.
2, roller controller according to claim 1 is characterized in that the carrying wheels of described topping roll top and the carrying wheels of bottom roll below are symmetrical arranged or asymmetric setting.
3, roller controller according to claim 1 is characterized in that the surface of described each bearing wheels adds nylon jacket.
4, roller controller according to claim 1 is characterized in that the wheel face material selection hardness of described each bearing wheels is lower than the material of roller surface hardness.
