Description
Technical field
The utility model relates to the Electrical Control Technology of aluminium process equipment, specifically a kind of stretch bending-straightening machine set control system of aluminium strip process equipment.
Background technology
Tension levelling line is be used to improving the aluminium processing finishing equipment of aluminium sheet template glacing flatness.The aluminium sheet blank of producing with hot rolling or casting is after cold rolling, because the shape of technological parameter, equipment level, roll forming roll gap, the reaction force of metal pair roller make the roll bending, the distortion heat of metal expands roll, although roll is ground to certain convexity according to technological requirement, but the fluctuation due to some rolling factor, the larger variation that also can cause roll forming makes extending longitudinally inhomogeneous on width of aluminium strip, this is arranged and the internal stress that produces, will cause aluminium strip to produce wave.What on general technology, often occur has: bilateral wave, monolateral wave, middle wave, both sides of the chest wave etc. even also have warpage, lateral bending and the defects such as wooden dipper song and potential bad plate shape end to end.If these defects are not eliminated, will affect the deep processing of band, more can not the high-level requirement of satisfying the market.The surface and the bad various defects of plate shape that for eliminating aluminium strip, produce in cold-rolled process, clean and stretch-bend leveller the aluminium strip after cold rolling with regard to using stretch bending to rectify machine.
Stretch bending-straightening machine is according to the elastoplasticity of material, to extend theory band is carried out to leveling.Its basic principle is the bending roll of many groups minor diameter of arranging by alternatively up and down continuously under the tension force effect that the jockey pulley group applies of band, under in combining of stretching and bending, using, produced along its length the extending longitudinally of plasticity, the length of each longitudinal fiber of band is trended towards unanimously, thereby reduce the inhomogeneities that the inner vertically internal stress of band distributes, improve the glacing flatness of band.Stretch bending-straightening machine is comprised of roll leveller and tension flattening machine two parts, therefore combine well the advantage of roll leveller and tension flattening machine, in the situation that tensile stress level can be realized than large plastometric set far below Materials Yield Limit, when improving the glacing flatness of thin plate, also help the anisotropy of improving material and avoid yield point elongation and stop the formation of skid wire, for the aluminium strip rolling continuous straightening of wider range provides may.
Tension levelling line mainly is comprised of uncoiler, cleaning, drying, entrance jockey pulley group, outlet jockey pulley group, smoothing roll, end trimming shears, coiling machine etc.By tension force and the speed control specific elongation steadily of controlling jockey pulley group and uncoiling, coiling machine, produce ejecting plate shape and the qualified finished product volume of surface quality.
Aspect Electrified Transmission control, owing to all using now direct current generator as transmission device, although it has good speed adjusting performance and startability, it is higher to environment for use and attendant's level requirement, needs often maintenance and fault rate also higher.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of stretch bending-straightening machine set control system that can the aluminium strip process equipment that simplified apparatus is safeguarded, good to power adaptation, energy consumption is low is provided.
The stretch bending-straightening machine set control system of aluminium strip process equipment of the present utility model, include the entrance tension motor that is connected with one group of entrance jockey pulley of smoothing roll entrance side, with one group of outlet tension motor, uncoiling motor, reel-motor that the outlet jockey pulley is connected of smoothing roll outlet side; Described uncoiling motor, entrance tension motor, outlet tension motor, reel-motor are alternating current generator, and by inversion unit, are connected on dc bus respectively, and dc bus connects AC network by rectification unit; During aluminium strip process stretch bending-straightening machine, outlet tension motor and reel-motor consume electric energy as motor, and uncoiling motor and entrance tension motor are exported electric energy by inversion unit to dc bus as generator.
On described dc bus, also be connected with brake unit.
Advantage applies of the present utility model exists: 1, utilize the different operating state of entrance side and outlet side motor, make the motor of entrance side when for aluminium strip, providing tension force, can be used as generator and input electric energy to system, thereby saved equipment energy consumption; 2, utilize alternating current generator as power source, plant maintenance facilitates, has strengthened the adaptability to power supply.
