Technical field

The present invention relates to a kind of rolling-mill housing, this rolling-mill housing such as can be used in hot rolling such as metal band or trim panel etc. The device of flat articles.

Being applied to the rolling-mill housing of the present invention can be traditional for reversible, but can also to be not limiting as the present invention.

Background technology

Known rolling-mill housing is used in the device of hot rolled flat product, and rolling-mill housing includes at least two roller, metal Band or trim panel pass through and along with metal band or trim panel move ahead and be rolled between described at least two roller.

It is also known that rolling-mill housing includes four rollers, i.e. top working roll, bottom working roll, top braces roller and Bottom support roller.

These rollers are supported on its respective end by respective roll chock, and roll chock is through being arranged on supporting construction Or on shoulder, slide in the direction orthogonal along expansion direction axial with roller.

Flat articles is made to pass through between top working roll and bottom working roll.Top braces roller abuts against top work Roller, and bottom support roller abut against bottom working roll.Top braces roller and/or bottom support roller facing to top working roll and/or Bottom working roll and move, in order to limit the predetermined and required degree of crook of top working roll and/or bottom working roll, Thus with the deformation contrast produced because of roll-force.

Under normal circumstances, linear actuators top braces roller and/or the predetermined movement of bottom support roller are controlled.

Known reversible rolling-mill housing, such as, reversible rolling-mill housing has bigger hole between the rolls, wherein, as Generally this area as, linear actuators is hydraulic cover, hydraulic cover be positioned at the bottom of shoulder window and adjust bottom prop up Support roller position, and screw mechanical adjustment can be positioned at shoulder window top adjust top braces roller position.Known Solution be to be adjusted the position of top braces roller by linear actuators or hydraulic cover.

Linear actuators can be simple effect type or double effect type.

As it is shown in figure 1, the bottom support roller indicated by reference 24 can be in end by the first roll chock 40 Support.First roll chock 40 is fixed against respective supporting construction or shoulder 22.Each shoulder 22 is configured to allow first to roll Roll bearing seat 40 moves along the direction orthogonal with bottom support roller 24 axis direction.

Linear actuators 30 is arranged on shoulder 22, and provides to support the first roll chock 40, and may with What bottom support roller 24 axis direction was orthogonal just moves the first roll chock 40 upwardly along shoulder 22.To this end, linear actuators 30 are provided with activation axis line along the direction orthogonal with bottom support roller 24 axis direction.

One typical defect of known rolling-mill housing 10 is due to the fact that in the operation of rolling, distributed load effect On bottom support roller 24, this produces thrust and causes bottom support roller 24 to produce downward flexural deformation.

Act on the distributed load on bottom support roller 24 to transmit successively as acting on the stress on linear actuators 30.

The bending that bottom support roller 24 bears can allow the Stress decomposition acted on linear actuators 30 for acting axially on The stress of linear actuators 30 and act laterally on the stress of linear actuators 30 axis, i.e. shown in Fig. 1 with T indicate tangential Power.

Owing to having frictional force between thrust plate 14 and gripper shoe 12, therefore, tangential force T is also delivered to linear actuators On 30, produce the tilting moment of a pair active force that Fig. 1 indicates with F.

The tilting moment acted on this linear actuators 30 can be discharged into such as the linear actuators such as sealing member and guidance tape In the sealing of 30 and director element 38, determine the hydraulic packing of infringement linear actuators 30 with this thus cause permeability or leakage of oil Premature abrasion and/or its disrepair phenomenon.

Additionally, the tilting moment acted on linear actuators 30 can also be discharged into those of composition linear actuators 30 On element, such as piston 34 and chuck 32, the most for good and all destroy these elements and/or make it deform.

In the worst hypothesis, the abrasion of composition those elements of linear actuators and parts can motion portion and fixed part it Between produce mechanical interference, and rolling device can be blocked subsequently, or be likely to destroy other elements or the mechanism of rolling-mill housing.

According to an aspect of the present invention, rolling-mill housing 10 includes that at least one puts element 20, described between put element 20 Extending between two relevant to roller linear actuators 30, the most described roller is shown as bottom support roller 24.Between Put element 20 to be positioned to be fixed against two linear actuatorss 30.Additionally, two the first roll chocks 40 are positioned sequentially to rely on Element 20 is put in.So, putting element 20 is inserted between linear actuators 30 and the first roll chock 40, but to them also Unrestrictedly, i.e. it is not attached to linear actuators 30 or the first roll chock 40, but is only in contact with it.

According to possible solution, putting element 20 is substantially integrated into plate.

Between put element 20 and continuously extend to the top of linear actuators 30, at least cover between the distance of linear actuators 30 is Put element 20 and the separate distance of linear actuators 30.

According to variant, a direction putting the main edge of element 20 parallel with the direction that rotation axis of roller X determines is launched.

According to feasible embodiment, can propose, linear actuators 30 and roll chock with put contacting of element 20 District size-constrained, and put the expansion on the whole surface of element 20 between being less than.This solution makes to reduce between acting on and puts Element 20, frictional force between linear actuators 30 and roll chock.

According to the solution shown in Fig. 3, Fig. 4 and Fig. 5, the first roll chock 40 be positioned to by thrust plate 14 and Put element 20 and contact (in this case for relying on).Thrust plate and put the contact surface of element 20 have be less than between put element The extension size of 20.

According to the solution in Fig. 2 to Fig. 5, putting element 20 can include central body 21, and this central body 21 sets Being equipped with core 11 and expansion 15, the thickness of expansion 15 is thicker than core 11, during expansion 15 is arranged on The end of heart part 11 position consistency of the first roll chock 40 with dependence setting.

Expansion 15 thickeies the first roll chock 40 and puts between element 20 and linear actuators 30 and put unit Contact area between part 20, strengthens the toleration of stress suffered by the latter with this.Possible solution according to one, one or many Individual first contact element 16 can put element 20 between being attached to, during use, face and be positioned to contact with its gripper shoe 12, line Property actuator 30 contacts, and is fixed against linear actuators 30 in this case, such as, is fixed against gripper shoe 12.

According to other variants, one or more second contact elements 18 can be put between being attached on element 20, such as, position Cheng Yuqi thrust plate 14 contacts, and the first roll chock 40 is fixed against described contact element 18 in this case.

Gripper shoe 12, thrust plate 14, for the first time osculating element 16 and second time osculating element 18 can be by high-abrasive material systems Become, i.e. use adamantine material, to tolerate the abrasion being subject to during they use.Additionally, gripper shoe 12, thrust plate 14, the first contact element 16 and the second contact element 18 all can be detachably attached to the first roll chock 40, Put element 20 and linear actuators 30, thus be replaced.

When rolling-mill housing 10 works, i.e. when flat articles 19 at least bottom support roller 24 and top braces roller 26 it Between and bottom working roll 28 and top working roll 29 between compacting time, due to the existence of suppression power, at bottom support roller Create distributed load above in the of 24, indicate (Fig. 4) with arrow L.

The distributed load L acting on bottom support roller 24 determines that the flexing of bottom support roller 24, flexing often lead to bending.

The effect of bending also can affect the first roll chock 40 supporting bottom support roller 24.

Owing to there is flexing, bottom support roller 24 often makes the first roll chock 40 tilt, and makes the first roll chock The vertical axis (axis that the i.e. first roll chock 40 is movable along) of 40 rotates an angle (Fig. 4) in plane Z.

According to variant, if arranging thrust plate 14, owing to it is associated with the first roll chock 40, therefore as towards The result of the external rotating of rolling-mill housing 10, it moves according to arrow T target direction.

If thrust plate 14 equally directly contacts with gripper shoe 12 with prior art, then due to thrust plate 14 and gripper shoe 12 Between frictional force, it will produce tangential force, use arrow T labelling.Additionally, due to the existence of tangential force, the power of toppling also can be produced Square, acts on linear actuators 30.

Unlike the prior art, i.e. if the combination acting on the arrow F of identical linear actuators 30 produces tilting moment (seeing Fig. 1), then tangential force T produced in rolling-mill housing 10 can because of between put the existence of element 20 without generation tilting moment (seeing Fig. 4).

Element 20 is put, it is allowed to discharge tangential force T between inserting between the first roll chock 40 and linear actuators 30, anti- Only active force is loaded into linear actuators 30, thus avoids the generation of tilting moment.

With act on bottom support roller 24 opposite end provide support the first roll chock 40 tangential stress compared with, The tangential force T substantially size acting on the first roll chock 40 is identical, and has contrary direction.This can cancel out each other Completely by between put tangential force T that element 20 absorbs.This situation distributed load L act on substantially with in bottom support roller 24 Occur more time on the bottom support roller 24 that line is symmetrical.This stress condition puts element 20 between avoiding having to and being provided with Laterally contain device associating, thus prevent from along between the direction horizontal transfer parallel with rotation axis line X, putting element 20 and producing Tangential force T.

According to variant, putting element 20 must not be along the direction translation parallel with rotation axis X, and only along vertical axis Direction is vertically moved, in order to allows discharge to act axially on linear actuators 30, is i.e. parallel to the stress of described direction D.

According to some conceptions of the present invention, if the load acting on its surface is unequal, then it is proposed that, put element 20 Arrange and laterally contain element to put, between accommodating, the transverse shifting that element 20 may produce because of tangential stress.

According to the variant used described in Fig. 5, put element 20 and can and be only allowed in and between described direction D parallel direction moves Put element 20 and with rotation axis X parallel direction or be different from receiving and the guiding that the direction of described direction D stops it to move Element 46 is associated.This receiving and director element 46 may be installed in supporting construction 25, thus allow between discharge, to put element 20 can Shearing stress T that can be subject to.Accommodate and the existence of director element 46 although describing with reference to the structure shown in Fig. 2 to Fig. 5, but Can not get rid of and they can also be set under the conditions of doing necessary modification for other solutions described here and unshowned.

According to the solution described in Fig. 5, accommodate and director element 46 includes at least one guide finger 50 and determines slidably Position, guide and control the directed cavity 51 of guide finger 50.Guide finger 50 and directed cavity 51 are such as, consistent with supporting construction 25, or phase Anti-inconsistent with supporting construction 25, put between being arranged on element 20 and be separately positioned on the fixed part of rolling-mill housing 10, with Limit the most dual guide frame.

According to the solution described in Fig. 5, element 20 put by guide finger 50 between being attached to, highlight cantilever, example relative to the latter As, consistent with its perimeter side.On the contrary, directed cavity 51 is formed on bracing frame 52, it is possible to be attached in supporting construction 25, this In the case of, it is possible to it is attached to shoulder 22.

In the actuation process of linear actuators 30, guide finger 50 slips in directed cavity 51 with guidance mode, uses restraint To keep substantially parallel with vertical axis Z.

Guide finger 50 puts element 20 along except the direction in the limited direction of vertical axis Z between may be configured to prevent, i.e. remove The direction of described direction D is moved.

Obviously, as described above, rolling-mill housing 10 can be carried out change and/or the interpolation of parts, without departing from this Bright field and scope.

Such as, although in current description, putting element 20 has been depicted as being associated with bottom support roller 24, i.e. rolls Roll bearing seat 40 and linear actuators 30 are associated with bottom support roller 24, but, it is not excluded that putting element 20 can be with top Support in roller 26, bottom working roll 28 or top working roll 29 or the respective roll chock being associated and actuator One or another one or a combination thereof be associated.

Obviously, although the present invention is explained according to some specific examples, but those skilled in the art one are surely Enough realize a lot of other equivalent form of values of rolling-mill housing, these equivalent form of values have in claims propose feature, therefore, All these equivalent form of values belong to the protection domain thus defined.
