Abstract
The invention discloses an edging roll device of a rolling mill. The edging roll device comprises edging motors, speed reducers and edging rolls connected with the speed reducers. The edging rolls are arranged on an edging roll base, and an overrunning clutch is arranged between each edging motor and the corresponding speed reducer. Owning to the overrunning clutch added between each edging motor and the corresponding speed reducer, a strip stops advancing and the overrunning clutches are closed once the strip slip from the rolls, and the edging rolls are driven to edge actively and feed the strip to the rolls forcedly; once the strip is engaged and rolled by the rolls, the overrunning clutches are separated automatically due to the fact that the rolling speed is higher than the edging speed, and thus, damage to equipment due to internal stress generated by mismatching of speeds of the strip drive by the rolling motor and the edging motor is avoided. The rolls and the edging rolls have good synchronism, the quantity of the edging rolls is not required to be reduced, and broadsiding fluctuation of the rolled strip is small and is convenient to control.
Description
Technical field
The present invention relates to sheet metal strip rolling equipment technical field, especially relate to a kind of Edger roll device of milling train.
Background technology
At present, in the hot rolling production of sheet metal strip, particularly the hot rolling of copper plate/strip is produced, and controls the change of spreading by using Edger roll device.Existing Edger roll device comprises motor, decelerator, Hooks coupling universal coupling, edger roll, in the actual operation of rolling, edger roll is driven by the motor of edging, edger roll is nipped after setting roll gap copper plate/strip edging force feeding to milling train, the roll of milling train is nipped after copper plate/strip and is continued rolling, and stop the motor of edger roll to drive, drag copper plate/strip advance by roll bite force and realize edging.
Existing Edger roll device is in actual use due to the backward pull pulling function of edger roll, roll is made often to occur skidding in the dragging sheet metal strip operation of rolling, only have and realize edging by reducing edger roll quantity, edger roll quantity spreads fluctuation greatly less, spreads and is difficult to control.
As do not stopped the motor of edging to drive after copper plate/strip nipped by roll, reducing the backward pull of edger roll, speed can be caused to be difficult to coupling because of the advancing slip and rear cunning existed in rolling and edging process, form very large internal force and be difficult to eliminate, cause device damage.Be difficult to realize roll and edger roll active drive simultaneously, do not interact again in the operation of rolling.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of Edger roll device of milling train, and to reach roll and edger roll, to rotate synchronism good, rolled strip spread fluctuation little, be convenient to the object that controls.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of Edger roll device of milling train, the edger roll comprising edging motor and decelerator and be connected with decelerator, edger roll is located on edger roll support, is provided with freewheel clutch between described edging motor and decelerator.
Also comprise edging roll gap governor motion, described edging roll gap governor motion comprises hydraulic cylinder, bearing block, bearing, and bearing block can the track on edger roll support move, and hydraulic cylinder is connected with bearing block.
Described freewheel clutch is wedge overrunning clutch.
The present invention compared with prior art, have the following advantages: by setting up a freewheel clutch between the motor and decelerator of edging, once occur skidding between roll and band, when band halts, freewheel clutch can be in conjunction with, drive edger roll active edging and force feeding to roll system, band is once again be nipped rolling by roll, because mill speed is higher than the speed of edging, freewheel clutch can be thrown off automatically, prevent band under rolling and edging two motors drive because speed does not mate generation internal stress, cause the damage of equipment.It is good that roll and edger roll rotate synchronism, need not reduce edger roll quantity, rolled strip spread fluctuation little, be convenient to control.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this description and the mark in figure are briefly described:
Fig. 1 is strip-rolling operating diagram of the present invention.
Fig. 2 is Edger roll device organigram of the present invention.
In figure: 1. band, 2. edger roll, 3. roll, 4. edging motor, 5. freewheel clutch, 6. decelerator, 7. Hooks coupling universal coupling, 8. edger roll support, 9. bearing block connection bracket, 10. hydraulic cylinder.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of Edger roll device of milling train, comprise edging motor 4, freewheel clutch 5, decelerator 6, Hooks coupling universal coupling 7, edger roll 2, edging motor and freewheel clutch, to be all connected by power transmission shaft between freewheel clutch and decelerator, decelerator is fixed on the top of mill housing by flange, edger roll 2 is arranged on edger roll support 8, and one end of decelerator and edger roll is connected by Hooks coupling universal coupling.
Further, this device also comprises edging roll gap governor motion, and edging roll gap governor motion comprises hydraulic cylinder 10, bearing block, bearing, and the two ends of edger roll 2 are arranged on bearing block by bearing, bearing block can the track on edger roll support 8 move, and hydraulic cylinder 10 is connected with bearing block.Further, be provided with bearing block connection bracket 9 between bearing block and hydraulic cylinder 10, the bearing block at same edger roll two ends links together by bearing block connection bracket 9, Synchronization Control.By the piston rod impeller-hub bearing connection bracket of hydraulic cylinder, and then change the A/F between a pair edger roll, thus reach the object of the width of adjustment band edging.
Preferably, freewheel clutch 5 is wedge overrunning clutch, good operating stability.
In the present invention, in band 1 operation of rolling, band 1 is first nipped by edger roll 2 and is forced feeding to roll 3 direction, roll is rolled with band of nipping higher than the speed of edger roll, because the speed of roll rolling is higher than the speed of edger roll, after band is nipped by roll, edger roll is in the passive as-rolled condition dragged by band, at this moment the speed of edger roll actual rotation is higher than the actuating speed of edging motor, freewheel clutch is in disengagement released state automatically, and edging motor is in running no load state.The power pulling band to carry out edging relies on the bite force of roll to provide.
Because the coefficient of friction between roll and band is by various factors such as temperature, emulsion, mill speeds, carry out in the process of edging at dragging edger roll, due to the pulling force effect backward that edging produces, easily cause and skid between roll and band and the operation of rolling cannot be continued.Once occur skidding between roll and band, when band halts, freewheel clutch can recombine, drive edger roll active edging and force feeding to roll system, band is once again be nipped rolling by roll, because mill speed is higher than the speed of edging, freewheel clutch can be thrown off again automatically, prevents band under rolling and edging two motors drive because speed does not mate generation internal stress, causes the damage of equipment.It is good that roll and edger roll rotate synchronism, need not reduce edger roll quantity, rolled strip spread fluctuation little, be convenient to control.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
