Description
Technical field
This utility model belongs to the electric automatization field for shaped steel and Heavy-rail Production, particularly relates to a kind of multiple roll shaped steel heavy rail straightening machine and controls system.
Background technology
In shaped steel and Heavy-rail Production, aligning is important procedure, by smoothing roll, the steel after rolling cooling is carried out extruding and makes it change linearity, eliminates residual stress.See Fig. 1, multi-roll straightening machine adopts two row's smoothing rolls, top roll 5, lower roll 4 (horizontal smoothing roll), left and right also sets up vertical smoothing roll, and axial, radial direction location, sharing of load, smoothing roll angle, the hole shape etc. of smoothing roll are the key factors affecting leveling effect.Leveller equipment is complicated, and control requirement and precision to equipment are all significantly high.
For straightener drive system, it is common to adopt motor, reduction gearing distributor box, safety coupling, Hooks coupling universal coupling to the kind of drive of smoothing roll.During aligning, due to length direction generation plastic deformation, cause existing between steel and smoothing roll speed difference, thus produce additional torque；Simultaneously when smoothing roll produces speed difference with steel, steel skidding meeting injured surface, in order to avoid the generation of these phenomenons, smoothing roll adopts driven separately.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of multiple roll shaped steel heavy rail straightening machine and controls system, it is achieved the Collaborative Control of all smoothing rolls of straightener, it is prevented that shaped steel and heavy rail skid, and improve leveling effect.
For achieving the above object, this utility model is achieved through the following technical solutions:
A kind of multiple roll shaped steel heavy rail straightening machine controls system, including control smoothing roll converter, drive smoothing roll drive motor, adjust smoothing roll axial/the adjustment motor of depressing position, also include PLC, man machine interface, encoder, each smoothing roll is by the Frequency Converter Control of a platform independent, and each smoothing roll is adjusted position by single adjustment motor；Converter is connected with drive motor, PLC is connected with converter, and PLC is connected with adjusting motor by catalyst, and PLC is connected with man machine interface by netting twine, encoder is connected with the adjustment motor of smoothing roll, drive motor, and encoder and PLC communicate.
Described man machine interface is provided with PORT COM, and PORT COM connected with network cable is passed through in man machine interface.
Compared with prior art, the beneficial effects of the utility model are:
Each smoothing roll is by the Frequency Converter Control of a platform independent, each smoothing roll is driven by a drive motor, the independent control of smoothing roll can be realized, when smoothing roll produces speed difference with steel, can adjust in time, avoid skidding, achieve the Collaborative Control of all smoothing rolls of straightener, utilize PLC control realization speeds match, spatial load forecasting during different drafts, management to the axial of different steel grades and pressure data, automatic Zero positioning, efficiency and the straightening quality of straightener in heavy rail and Section Steel Production process can be effectively improved, reduce percent defective, and it is avoided that strong disconnected phenomenon, alleviate labor strength.

In figure: the 1-heavy rail 2-horizontal smoothing roll vertical smoothing roll of 3-.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in detail, it should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 2, a kind of multiple roll shaped steel heavy rail straightening machine controls system, including control smoothing roll converter, drive smoothing roll drive motor, adjust smoothing roll axial/the adjustment motor of depressing position, also include PLC, man machine interface, encoder, each smoothing roll is by the Frequency Converter Control of a platform independent, and each smoothing roll is adjusted position by single adjustment motor；Converter is connected with drive motor, PLC is connected with converter, and PLC is connected with adjusting motor by catalyst, and PLC is connected with man machine interface by netting twine, encoder is connected with the adjustment motor of smoothing roll, drive motor, and encoder and PLC communicate.
Man machine interface is provided with PORT COM, and PORT COM connected with network cable is passed through in man machine interface, and by Ethernet and PLC communication, controls parameter by man machine interface adjustable PLC, can show smoothing roll duty in real time simultaneously.
Automatically controlling of straightener is realized by PLC.PLC is by PLC machine frame, CPU, communication controller, fieldbus network, remote I/O.PLC, by communication network and man machine interface exchange data, stirs and make muddy data with converter by fieldbus network.
The adjustment motor of smoothing roll is mounted on axial encoder, pressure encoder, is used for measuring axial location.Straightener top roll has press function (radial motion), with pressure encoder, is used for measuring depressing position.Axially control axially to adjust motor with pressure respectively through PLC realize with the adjustment of depressing position.PLC is according to pressure and axial setting value, and is read calculated positional value by encoder, automatically controls the action of pressure and axially adjustable motor so that it is reach the setting value of hole shape requirement.Produce after adjusting the position of smoothing roll, during production, control converter by PLC, by Frequency Converter Control drive motor.According to spatial load forecasting state modulator drive motor set in advance.
In straightening process, the linear velocity at each smoothing roll edge must be consistent, otherwise can produce smoothing roll skidding, due to the roller footpath of each smoothing roll inconsistent (being determined by steel grade and steel specs), it is necessary in a control program aligning speed to be converted the speed preset of each smoothing roll.
As the control system of straightener, use with multiple roll heavy rail section straightener mechanical equipment coordination.When equipment uses for the first time, must determine that smoothing roll is axially and depressing position demarcation in man machine interface.After first use or replacing smoothing roll, smoothing roll roller footpath parameter must be inputted in man machine interface, in man machine interface, then call mark zero power energy automatically.After mark zero completes, can determine axially and depressing position setting value according to steel specs, steel grade, then control program and will be automatically performed location.The setting data of different steel grades and specification can preserve, and can call at any time.When calling data, raising by previously saved data in man machine interface, after confirmation, these data will become current setting value.
Its drive motor power of the smoothing roll of diverse location is not quite identical, according to smoothing roll its load coefficient of drive motor power setting, it is therefore desirable to converter adjusts in real time.Due to smoothing roll drive motor and arrangements for speed regulation characteristic thereof, in order to ensure that start and stop synchronize, in control program, each roller start-stop time of ascent algorithm may be inconsistent, must finely tune in conjunction with practical situation.
The Collaborative Control of all smoothing rolls of straightener can be realized, spatial load forecasting during including speeds match, different drafts, to different steel grades axially and the pressure management of data, automatic Zero positioning, efficiency and the straightening quality of straightener in heavy rail and Section Steel Production process can be effectively improved, reduce percent defective, and be avoided that strong disconnected phenomenon, alleviate labor strength.
