Abstract
The utility model relates to a cold rolling field of belted steel especially relates to a roll bearing structure. A cold rolling mill roll bearing structure, includes and erects the roll on a pair of bearing frame through the pivot, and is a pair of the bearing frame on be provided with independent vertical motion respectively, vertical motion drives one end along the vertical direction motion of roll, the outside terminal surface of bearing frame is the wedge inclined plane, and the outside of bearing frame is provided with auto -lock motion and auto -lock clamp plate, the auto -lock clamp plate cooperatees with the wedge inclined plane, the auto -lock motion drives auto -lock clamp plate along horizontal direction motion for the auto -lock clamp plate compresses tightly the laminating on the wedge inclined plane. The utility model discloses cold rolling mill roll bearing structure utilizes the latching characteristics on inclined plane to set up an auto -lock clamp plate in the side of roll support, has thoroughly stopped the possibility that the roll kick -backs through the auto -lock clamp plate, has greatly improved rolling mill rigidity in other words, has reduced roll gap control's the degree of difficulty, and then has improved the plate -type quality.
Description
Technical field
The utility model relates to cold rolling of strip steel field, particularly relates to a kind of roll support structure.
Background technology
In order to realize, to the control of version type, freely controlling roll gap, the support both sides of rolling mill roll are respectively by one group of hydraulic mechanism self contained function, and when regulating, the precision of roll gap is directly connected to the template parameters such as slab thickness, lateral thickness difference, Bian Lang.
In order to improve strip shape quality in prior art, usually all according to online template data, roll gap can be regulated, need to consider a lot of coefficient in adjustment, wherein housing rigidity is a wherein important ring, directly affects the accuracy of control, housing rigidity is higher, pressurized resilience is less, then easier when determining control program, therefore the roll support structure that a kind of rigidity is large, resilience is little is needed, to improve strip shape quality.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of cold-rolling mill roll support structure and utilizes the latching characteristics on inclined-plane to arrange a self-lock pressing plate in the side of roller bracket, the possibility of roll resilience has thoroughly been stopped by self-lock pressing plate, be equivalent to greatly improve mill stiffness, reduce the difficulty of gap preset, and then improve strip shape quality.
The utility model is achieved in that a kind of cold-rolling mill roll support structure, comprise the roll be located at by spindle housing in pair of bearing, bearing block described in a pair is respectively arranged with independently vertical motion mechanism, vertical motion mechanism drives one end of roll vertically to move, the end face outside of described bearing block is tapered ramp, the arranged outside of bearing block has self-locking motion and self-lock pressing plate, described self-lock pressing plate matches with tapered ramp, described self-locking motion drives self-lock pressing plate to move in the horizontal direction, self-lock pressing plate is compressed be fitted on tapered ramp.
The tapered ramp of described end face outside and the angle of horizontal plane are 30 ~ 75 °.
Described vertical motion mechanism is hydraulic cylinder.
Described self-locking motion is hydraulic cylinder.
The utility model cold-rolling mill roll support structure utilizes the latching characteristics on inclined-plane to arrange a self-lock pressing plate in the side of roller bracket, the possibility of roll resilience has thoroughly been stopped by self-lock pressing plate, be equivalent to greatly improve mill stiffness, reduce the difficulty of gap preset, and then improve strip shape quality.

Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model statement.
Embodiment 1
As shown in Figure 1, a kind of cold-rolling mill roll support structure, comprise the roll 3 be erected at by rotating shaft 1 in pair of bearing 2, bearing block 2 described in a pair is respectively arranged with independently vertical motion mechanism 4, vertical motion mechanism 4 drives one end of roll 3 vertically to move, the end face outside 5 of described bearing block 2 is tapered ramp, the arranged outside of bearing block 2 has self-locking motion 6 and self-lock pressing plate 7, described self-lock pressing plate 7 matches with tapered ramp, described self-locking motion 6 drives self-lock pressing plate 7 to move in the horizontal direction, self-lock pressing plate 7 is compressed be fitted on tapered ramp.
During layout, top and bottom rolls arranges same self-lock pressing plate, simplifies the variable of required consideration during Strip Shape Control, is conducive to improving strip shape quality.
In the utility model, the tapered ramp of described end face outside 5 is relevant with the coefficient of friction chosen between end face outside 5 of the angle angle of horizontal plane, this angle is not more than 75 ° under normal circumstances, but considers the factor in field apparatus space, is 30 ~ 75 ° at set angle.
In the present embodiment, described vertical motion mechanism 4 is hydraulic cylinder, and described self-locking motion 6 is hydraulic cylinder.
