Description
Technical field
The utility model belongs to technical field of metallurgical equipment, relates in particular to a kind of working roll axial locking device.
Background technology
The axial force that working roll axial locking device is used for axial restraint working roll and bears working roll, it can eliminate the axial displacement between working roll, reduces the shock loading of working roll, improves the stability of working roll in frame, increases the service life of bearing.
On tandem mill, for adapting to the requirement of fast roll changing, existing working roll axial locking device is arranged in fore side frame, adopts movable separately clamp or pressing plate axial locking working roll, with Driven by Hydraulic Cylinder clamp or pressing plate, carries out stretching motion.Hydraulic cylinder is connected with frame by hydraulic cylinder leg, and clamp or pressing plate can move under fixed block guide effect.According to These characteristics, situation when this axial locking scheme is relatively applicable to working roll without horizontally moving functions.The milling train for working roll with horizontally moving functions, when working roll moves horizontally, need to first open working roll axial locking device conventionally, moves horizontally the complete axial locking that carries out again.Therefore for the sake of security, these operations all can only complete by off-line.And due to moving horizontally of working roll, the stroke of axial locking hydraulic cylinder also must be increased, certainly will cause unnecessary side direction additional force to working roll bearing block.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of working roll axial locking device, the technical problem that is intended to solve existing apparatus complex operation and has certain risk.
The utility model adopts following technical scheme:
Described working roll axial locking device comprises roller bending block, described roller bending block has been opened guide hole, described guide hole is built-in with the locking cylinder of bore coupling, described roller bending block is also fixed with clamp, described locking cylinder comprise cylinder body and with the piston rod of cylinder body cooperating, described piston rod is vertically fixed on described clamp, cylinder body telescopic moving under the guide effect of roller bending block described in locking cylinder when work, and extended roller bending block is to the recess on working roll bearing block.
The beneficial effects of the utility model are: the utility model is arranged on axial locking device on roller bending block, concrete, piston rod is fixed by clamp and roller bending block, by cylinder body mobile locking working roll of realizing in roller bending block of locking cylinder, therefore locking cylinder can move horizontally with roller bending block, the stroke of locking cylinder can not change, and working roll axial locking is not moved horizontally by working roll to be affected; In addition, this working roll axial locking device is simple and reliable for structure, maintenance economical and practical and easy to operate.
Accompanying drawing explanation
Fig. 1 is the top view of the working roll horizontally moving device that provides of the utility model embodiment;
Fig. 2 is the front view of the working roll horizontally moving device that provides of the utility model embodiment;
Fig. 3 is that the AA of the working roll horizontally moving device that provides of the utility model embodiment is to cutaway view;
Fig. 4 is the structure chart of the working roll axial locking device that provides of the utility model embodiment.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
For technical scheme described in the utility model is described, below by specific embodiment, describe.
Fig. 1-Fig. 4 is respectively the top view, front view, AA of working roll horizontally moving device to the partial enlarged drawing of cutaway view and B part, the structure of the working roll axial locking device that the amplifier section showing in Fig. 4 provides for the utility model embodiment, only shows the part relevant to the utility model embodiment for convenience of explanation.
With reference to Fig. 1-Fig. 3, in thering is the milling train of working roll horizontally moving device, horizontally moving device generally all comprises that one for driving the driving mechanism 10 of roller bending block, when work, roller bending block 1 is clamped working roll bearing block 6 by roll-bending cylinder 11, then under the driving of driving mechanism, drive roller bending block, working roll bearing block to move horizontally; On the other hand, also need to fix working roll bearing block by rack-mounted working roll locking device, because existing working roll locking device is arranged in frame, when moving horizontally working roll, conventionally need to first open working roll locking device, move horizontally the complete axial locking that carries out again; And due to moving horizontally of working roll, the stroke of axial locking hydraulic cylinder also must be increased, certainly will cause unnecessary side direction additional force to working roll bearing block.
For head it off, it is a kind of by working roll axial locking device that the present embodiment provides, comprise roller bending block 1, described roller bending block 1 has been opened guide hole, described guide hole is built-in with the locking cylinder of bore coupling, the external diameter that is locking cylinder is slightly less than guide hole bore, described roller bending block is also fixed with clamp 4, described locking cylinder comprise cylinder body 2 and with the piston rod 5 of cylinder body 2 cooperatings, described piston rod 5 is vertically fixed on described clamp 4, because piston rod 5 is fixing, when therefore locking cylinder is worked, cylinder body 2 meeting telescopic movings under the guide effect of roller bending block 1, described working shaft bearing 6 correspondence positions are provided with recess, the top of described cylinder body is boss structure, and boss bore is not more than the recess bore on working roll bearing block, when needs locking action, cylinder body 2 stretches out roller bending block 1 to 6 recess on working roll bearing block, realizes axial locking, when cylinder body rollback, locking device is opened.
The present embodiment is arranged on locking device in roller bending block 1, and roller bending block 1, can be in the interior movement of fixed block 7 under the driving of driving mechanism 10, and this locking cylinder can move with roller bending block.When moving horizontally working roll, without unclamping locking device, directly mobile, operate more conveniently, and the stroke of locking cylinder can not change yet, the unnecessary side direction additional force of avoiding generation to cause working roll bearing block.
As a kind of concrete preferred structure, described clamp 5 is fixed on described roller bending block 1 by nut, is convenient to for convenience detach and installation locking device; Between described locking cylinder and roller bending block, be also provided with wear-resistant slide plate 3, described wear-resistant slide plate 3 can reduce friction on the one hand, can reduce the wearing and tearing to roller bending block and locking cylinder on the other hand.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
