Abstract
The invention discloses a rotary roll synchronizer for a levelling machine and belongs to the field of steel rolling machinery. The rotary roll synchronizer comprises a rack, a static part, a moving part and a working roll, wherein the static part comprises a pair of bearing seats fixed on the rack and synchronous rolls of which two ends are arranged in the bearing seats; the moving part comprises a flat plate; two sides of the flat plate are slidably arranged on the rack through a linear guide rail; two ends of the synchronous rolls are matched with the flat plate through gear rack structures; and a pair of oil cylinders are arranged between the rack and the flat plate and are used for driving the flat plate to move linearly; and the working roll and the synchronous rolls are parallelly arranged on the flat plate. By utilizing such a structure, the two oil cylinders are enabled to ascend and descend synchronously, so that anti-wrinkle rolls or anti-vibration rolls can be kept at horizontal positions, and the band steel rolling precision can be improved.
Description
Technical field
The present invention relates to a kind of synchronized, a kind of specifically planisher is used the transfer roller synchronized.
Background technology
In rolling process, at the entrance side and the outlet side of planisher a crease-resistant roller and a vibration-resistant roller are provided respectively, by two hydraulic cylinders and slideway its rising of control and decline, hydraulic cylinder is a power source respectively for they, its position is by these hydraulic cylinders lockings.In the process of using, because two hydraulic cylinders possible generation time in actual moving process is poor, because the asynchronous of hydraulic cylinder caused crease-resistant roller and vibration-resistant roller inclination, and then the rolling accuracy of influence band steel, need further make improvements.
Summary of the invention
The object of the present invention is to provide a kind of planisher to use the transfer roller synchronized, it can make two transmission devices keep rising synchronously or descending, thereby improves the rolling accuracy of band steel.
The present invention solves the technical scheme that its technical problem takes: a kind of planisher is used the transfer roller synchronized; It is characterized in that; Comprise frame, quiet portion, moving portion and working roll; Described quiet comprises that the pair of bearing and the two ends that are fixed on the frame are installed in the synchronous roller in the bearing block, and roller is rotatable synchronously; Described moving portion comprises a flat board; Said dull and stereotyped both sides slidably are installed on the frame through line slideway; And cooperate through gear & rack structure between roller two ends and the flat board synchronously; Like this in the process of treadmill exercise, because the existence of rack-and-pinion acting in agreement of can guaranteeing that moving plate moves up and down; A pair of oil cylinder is arranged between frame and the flat board, is power source, drives dull and stereotyped rectilinear motion; Said working roll laterally arranges with synchronous roller and is installed on the flat board, and dull and stereotyped rectilinear motion finally develops into the feeding and the setback of working roll.
Described flat board is a door shape.
Described working roll is crease-resistant roller or vibration-resistant roller.
Compared with prior art, the present invention has following beneficial effect:
Owing to be provided with synchronous roller, this synchronous roller can make dull and stereotyped acting in agreement of rising or descend, and improves its stability, thereby makes crease-resistant roller or vibration-resistant roller can remain on horizontal level, has improved the rolling accuracy of band steel.
Description of drawings
Fig. 1 is an agent structure sketch map of the present invention;
Among the figure: 1 frame, 2 bearing blocks, 3 first oil cylinders, 4 second oil cylinders, 5 flat boards, 6 line slideways, 7 synchronous rollers, 8 gear & rack structures, 9 working rolls.
The specific embodiment
Below in conjunction with Figure of description the present invention is done further description:
As shown in Figure 1, a kind of planisher is used the transfer roller synchronized, comprises frame 1, quiet portion, moving portion and working roll.
Quiet comprises that the pair of bearing 2 that is fixed on the frame is installed in the synchronous roller 7 in the bearing block with two ends, because the roller two ends are that bearing cooperates synchronously, so roller is free to rotate synchronously.
Moving portion comprises a flat board 5, and flat board is a door shape.Dull and stereotyped 5 both sides slidably are installed on the frame through line slideway 6, and line slideway is made up of chute and slide block, and concrete pattern belongs to existing mature technology, and specifications and models can be selected according to actual needs.A pair of oil cylinder is arranged between frame and the flat board, is labeled as first oil cylinder 3 and second oil cylinder 4, is power source, drives dull and stereotyped rectilinear motion, and wherein two oil cylinders and frame are articulated and connected, and piston cylinder is articulated and connected with dull and stereotyped 5.Working roll 9 laterally arranges and is installed on the flat board with roller synchronously, and the working roll two ends also connect through bearing, and dull and stereotyped rectilinear motion finally develops into the feeding and the setback of working roll.
Crucial part is; Cooperating through gear & rack structure 8 between roller two ends and the flat board synchronously, be exactly to be provided with tooth simultaneously specifically at the two ends of synchronous roller; The gear that is integrally formed; On flat board, be provided with it corresponding tooth bar, like this in the process of treadmill exercise, because the existence of rack-and-pinion acting in agreement of can guaranteeing that moving plate moves up and down.
The improvement of said mechanism can be used for crease-resistant roller or vibration-resistant roller mechanism, and so corresponding working roll is crease-resistant roller or vibration-resistant roller.
The course of work is such:
At first, under the control of control system, two oil cylinder synchronization actions are with dull and stereotyped jack-up; Working roll just rises to certain height like this, in this course, if the step of two oil cylinders has a little deviation, is reflected to synchronous roller two ends and is exactly; The stressed dynamics at roller two ends is different synchronously, because the rigidity of roller is bigger synchronously, span is less, so through about synchronous roller; Will between two oil cylinders, reach a balance, form synchronously preferably, realize synchronous purpose.
The above; Principles more of the present invention just explain through diagrams; This specification be not be to the present invention be confined to shown in described concrete structure and the scope of application, so every the modify and equivalent that might be utilized, the claim that all belongs to the present invention and applied for.
