Abstract
A rolling mill tension device after coil-opening comprises a coil opener, and is characterized in that one end of the coil opener is connected and fixed with one end of an output shaft of a speed reducer, one end of an input shaft of the speed reducer is connected and fixed with one end of a hollow shaft of a magnetic particle clutch, a constant current power supply is further assembled besides the magnetic particle clutch, and two output terminals of the constant current power supply are respectively and electrically connected with corresponding magnetic particle clutch coil terminals throughcables. The rolling mill tension device after coil-opening of the utility model can conveniently and effectively achieve the purpose of controlling tension force after coils are opened to enable rolled strip steel to have flat surface, even thickness and higher precision. The rolling mill tension device after coil-opening of the utility model is suitable for being applied on coil openers.
Description
Technical field:
The utility model relates to a kind of uncoiler, particularly relates to a kind of milling train decoiling back-tension device.
Background technology:
In the coil rolling process of band, employed equipment mainly includes uncoiler, band and strip rolling mill and winder, when sheet metal strip is rolling, the tension fluctuation that uncoiler unreels and winder batches directly has influence on the quality of product, unreeling of traditional uncoiler is generally free uncoiling or adopts the main shaft to uncoiler to increase damping, so change in coil diameter, during velocity variations, the control that promptly produces backward pull does not reach desirable effect, the strip-rolling poor stability promptly appears, precision is low, also can cause the band sideslip, phenomenons such as rolling thickness inequality even fracture make the quality of product can not get ensureing that product percent of pass also greatly descends simultaneously.Control is to adopt Programmable Logic Controller or single-chip microcomputer to realize that so not only complex structure, and cost height had both increased the weight of the investment burden of enterprise, also influenced Enterprises'Competitiveness to present employed uncoiler to tension force.
Summary of the invention:
The purpose of this utility model is that a kind of improved milling train decoiling back-tension control device will be provided, and it not only can make the milling train decoiling back-tension be effectively controlled, and, in the operation of rolling, also keep the stable of backward pull, and guaranteed the quality of product.
In order to realize that above-mentioned purpose the utility model proposes following design: milling train decoiling back-tension device of the present utility model comprises a uncoiler, one end of one end of the main shaft of described uncoiler and the output shaft of decelerator forms and is connected and fixed, one end of one end of described input shaft of speed reducer and the hollow shaft of magnetic powder cluth forms and is connected and fixed, the other stabilized current supply that also is equipped with of described magnetic powder cluth, two lead-out terminals of described stabilized current supply form by cable with the coil terminals of corresponding magnetic powder cluth respectively and are electrically connected.
Because the utility model has improved existing milling train decoiling back-tension device, adopt decelerator and magnetic powder cluth to realize jointly decoiling back-tension is controlled, magnetic powder cluth is according to electromagnetic principle and utilizes magnetic to pass on torque, the torque of its reception and registration and exciting curent are linear substantially, when exciting curent remains unchanged, the torque of its reception and registration is not subjected to the influence of slippage rotating speed between driving member and the driven member, be statical moment and kinetic moment indifference, can stably pass on constant torque, simultaneously, only need to regulate the size of exciting curent for tension force control, just can accurately control and pass on required torque, therefore, can be easy, reach the purpose of control decoiling back-tension effectively with decelerator, make institute's strip surfacing, thickness is even, can avoid coil diameter to change, velocity variations and no-load torque etc. are to the influence of backward pull, and precision is higher.
Description of drawings:
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of milling train decoiling back-tension device of the present utility model.
The specific embodiment:
Below with reference to accompanying drawing milling train decoiling back-tension device of the present utility model is described in further detail.
With reference to Fig. 1, the milling train decoiling back-tension device of this utility model comprises described uncoiler 1, described decelerator 3, described magnetic powder cluth 6 and described stabilized current supply 7.
One end of one end of the main shaft 2 of described uncoiler 1 and the output shaft 4 of described decelerator 3 forms and is connected and fixed, one end of one end of the power shaft 5 of described decelerator 3 and the hollow shaft of described magnetic powder cluth 6 forms and is connected and fixed, described stabilized current supply 7 is placed in one side of described magnetic powder cluth 6, and two lead-out terminals 8 of described stabilized current supply 7 form by cable 10 with the coil terminals 9 of corresponding described magnetic powder cluth 6 respectively and are electrically connected.
The use of milling train decoiling back-tension device of the present utility model, when the strip-rolling process, uncoiler 1 unreels action, band and strip rolling mill is rolling, be that uncoiler 1 forms backward pull, the big I of backward pull is by the knob 11 on the rotation stabilized current supply 7, regulate the size of the exciting curent of magnetic powder cluth 6, just can control the size of the torque of magnetic powder cluth 6, obtain suitable backward pull,, thereby obtain consistent tension force along with the knob 11 that the variation of coil diameter can be operated on the stabilized current supply 7 is stage by stage adjusted the exciting curent of magnetic powder cluth 6, synchronous with the linear velocity that guarantees uncoiling with the linear velocity of input mill milling band, the quality of ultimate guarantee output product.
Milling train decoiling back-tension apparatus structure of the present utility model is simple, easy to use, and the precision height.
Milling train decoiling back-tension device of the present utility model is suitable for using on the uncoiler.
