Abstract
The utility model relates to forging and pressing equipment for shaping metal material. A roller plate flattening machine comprises a movable row working roller, a row fixed working roller, a rack, a lifting apparatus of the movable row working roller, a main driving apparatus and an electric controlling apparatus, which is characterized in that a carrying roller is not arranged in the movable working roller row, respective vertical lifting apparatus is arranged on each roller of the movable row, all or part the fixed row working roller are provided with carrying rollers, the roller plate flattening machine with three rollers can adopt parallel flattening method or unparallel flattening method, and can adopt the art of variety number of rollers, so that the utility model is suitable for the condition of bigger inclined quantity of the movable row working roller thereby improving the flattening precision.
Description
Affiliated technical field
The utility model relates to a kind of forging equipment-gaugger of metal material shaping, specifically roller type leveling machine.
Background technology
Number of patent application 200510019391.2 " roller type leveling machine " discloses a kind of sheet material that dwindles in the difference of the deflection of both direction up and down, adopt not parallel rectification mode, improve and correct precision, can adopt simultaneously to become the roller type leveling machine that roller is counted triple rollers of technology; Triple rollers are meant that the two rows working roll adds row's backing roll down.The utility model is the expansion that this patent is used.One of feature of this patent " roller type leveling machine " is: adopt hinged connected mode between the elevating screw bottom of activity row working roll bearing block and movable row's working roll, satisfy the movable horizontal displacement that produces when arranging the working roll integral inclination by the strain of elevating screw and movement clearance that screw mandrel is paid; The mutual slip that does not produce horizontal direction between the elevating screw bottom of movable row's working roll bearing block and movable row's working roll.Be not suitable for the big situation of movable row's working roll tilt quantity in this way.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of roller type leveling machine can adopt parallel rectification mode and not parallel rectification mode, can adopt simultaneously and become the roller type leveling machine that roller is counted triple rollers of technology, and be fit to the big situation of movable row's working roll tilt quantity, improve and correct precision.
The technical solution of the utility model is, a kind of roller type leveling machine, comprise movable row's working roll, fixing row's working roll, frame, movable row's working roll lowering or hoisting gear, main drive, electric control gear etc., it is characterized in that: movable row's working roll is not established backing roll, movable each working roll of row is established independent vertical lift device, all or part of backing roll that is provided with of fixing row's working roll.Because movable row's working roll is not established backing roll, movable each working roll of row is established independent vertical lift device, movable row's working roll can adopt parallel rectification mode also can adopt not parallel rectification mode, mode such as can adopt that bolt is connected between the bearing block of independent vertical lift device and movable row's working roll, can not adopt hinged connected mode, can adopt the change roller to count technology easily, and be fit to the big situation of movable row's working roll tilt quantity, arbitrarily the drafts of each working roll is arranged in the adjustment activity.
The diameter of the part working roll of described activity whole working rolls of row or centre is greater than the diameter of the part working roll of fixing whole working rolls of row or centre.Can dwindle sheet material in the difference of the deflection of both direction up and down, the possibility that sheet material is elastic-plastic deformation at the 3rd roller place reciprocal increases, and improve and correct precision,
Described working roll is provided with the branch roll driving apparatus or divides row drive unit.The mechanical interference of avoiding not parallel rectification mode to cause.
Movable row's working roll is not established backing roll, does not have bigger local contact stress, and concentrated wear is little, and the life-span prolongs.Do not establish the rolling friction resistance that backing roll has also reduced working roll and backing roll, reduce main driving motor power.
The beneficial effects of the utility model are that the roller type leveling machine of triple rollers can adopt parallel rectification mode and not parallel rectification mode, can adopt the change roller to count technology simultaneously, is fit to the big operating mode of movable row's working roll tilt quantity, improves the rectification precision.
Description of drawings
Fig. 1 is one of the utility model embodiment: seven roller plate flattening machine working roll structural plans.Wherein: roller 1,2,3,4,5,6,7 is a working roll, and A1, A2 are backing roll.
Fig. 2 is two: nine roller plate flattening machine working roll structural plans of the utility model embodiment.Wherein: 8,9 is working roll, and A3, A4 are backing roll.
The specific embodiment
Fig. 1 is one of embodiment of the present utility model, seven roller plate flattening machines, among the figure 1,2,3,4,5,6,7 is working roll, 2,4,6 is movable row's working roll, no backing roll, two-way vertical arrows is represented working roll 2, working roll 4, working roll 6 respectively is provided with independent vertical lift device, arbitrarily the drafts of each working roll is arranged in the adjustment activity, owing to be vertical lift, lowering or hoisting gear can adopt bolt to be connected with movable row's working roll bearing block, the big tilt quantity peace row rectification mode of realization activity row working roll and the conversion of not parallel rectification mode, working roll 2, working roll 6 is provided with independent vertical lift device, can adopt the change roller to count technology easily; Become five rollers, three rollers by seven rollers; 1,3,5,7 are fixing row's working roll, be installed on the frame, A1, A2 is a working roll 3,5 backing roll, be installed on the sill or chassis between two frames, the whole working rolls 2 of movable row, 4,6 diameter is greater than the whole working rolls 1 of fixing row, 3,5,7 diameter, sheet material is the 2nd, 3,4,5,6 roller place co-variation shapes five times, the 6th roller place in discharging is a strain, the 2nd, 3,4,5 roller places are elastic-plastic deformation, and drafts successively decreases successively, the 2nd, 4 roller place sheet materials are bent downwardly, the 3rd, 5 roller place sheet materials are bent upwards, at the 2nd roller place drafts maximum, roller 1,3 diameters are less, at the 3rd roller place drafts second, but roller 2,4 diameters are bigger, dwindled sheet material in the difference of the deflection of both direction up and down, and sheet material at the 5th roller place because roller 4,6 diameter moderate finite deformation amounts increase, sheet material is that the possibility of elastic-plastic deformation increases at the 5th roller place, and precision is corrected in favourable raising.
Fig. 2 is two of embodiment of the present utility model, nine roller plate flattening machines, 2,4,6,8,9 is movable row's working roll among the figure, A1, A2, A3, A4 are the fixing backing roll of arranging working roll 3,5,1,7, two-way vertical arrows is represented working roll 2,4,6,8,9 vertical displacement movement separately, the diameter of the part working roll 2,4,6 in the middle of the movable row is greater than the diameter of the whole working rolls 1,3,5,7 of fixing row, after working roll 8,9 is raised to the disengaging duty, become seven roller plate flattening machines, identical with one of embodiment.Sheet metal thickness is less when being nine roller plate flattening machines, and roller 2,4,6,8,9 no backing rolls also can meet the demands.
Roller 1,3,5,7 is main driving, adopts and divides the roller actuation techniques, and roller 2,4,6 adopts auxilliary driving or passive, and main drive does not draw.
