The invention is further described with reference to the following detailed description and accompanying drawings.
Referring to fig. 1 to 5, a copper straightening variable frequency roller with a brake includes a straightening wheel 1, a flywheel 2, a brake mechanism 3, an electric control cabinet 4, a variable frequency motor 5, a speed sensor 6, and a controller 7, wherein:
the flywheel 2 is coaxially connected with the straightening wheel 1 and is driven to rotate by the variable frequency motor 5, so that the rotation inertia of the straightening wheel 1 is increased, the rotation is more stable, and the straightening effect is improved;
the number of the brake mechanisms 3 is at least two, and the brake mechanisms are arranged on the outer side of the flywheel 2 to generate pressure on the flywheel 2 so as to reduce the speed of the flywheel;
the speed sensor 6 is a photoelectric sensor, is arranged on the flywheel 2 and is electrically connected with the controller 7, so that the rotating speed of the flywheel 2 is fed back to the controller 7 in real time, and the brake release time is determined;
the electric control cabinet 4 is electrically connected with the variable frequency motor 5, a frequency converter and a variable frequency knob are arranged on the electric control cabinet, and the input frequency of the variable frequency motor 5 can be adjusted according to production requirements, so that the output rotating speed of the variable frequency motor 5 can be adjusted in an electrodeless way;
the controller 7 is electrically connected with the brake mechanism 3 and the electric control cabinet 4 so as to set according to the frequency of the electric control cabinet 4 and timely release the brake when the rotating speed of the flywheel 2 reaches a set value.
As shown in fig. 3 and 4, the brake mechanism 3 includes a pressing roller assembly 31, a fixing plate 32 and a pushing device 33, the pressing roller assembly 31 includes two side plates 311, a bottom plate 312, two pressing rollers 313 and a connecting block 315, the two side plates 311 are fixed on two sides of the bottom plate 312 in parallel, the two pressing rollers 313 are fixed between the two side plates 311 in a rotatable manner, the connecting block 315 is fixed on the other side of the bottom plate 312 far from the pressing rollers 313, and a connecting hole 316 is formed in the connecting block 315; the pushing device 33 is fixed on one side of the fixing plate 32, the telescopic shaft thereof passes through the fixing plate 32 and is fixed in the connecting hole 316, and the pushing device 33 is electrically connected with the controller 7 so as to control the movement of the pressing roller assembly 31.
In order to ensure the smooth rotation of the compression roller 313, two ends of the compression roller 313 are connected with the side plates 311 through bearings, and an end cover 314 is arranged on the outer side to prevent metal chips from entering to influence the rotation of the compression roller 313.
Because the outer side of the flywheel 313 is arc-shaped, in order to ensure that the compression roller 313 is attached to the side wall of the flywheel 2, the side plate 311 is concave-shaped with a low middle part and high two ends, and the compression rollers 313 are arranged at the two ends of the side plate 311.
In order to improve the braking force and enable the compression roller 313 to be separated from the surface of the flywheel 2 in time after the flywheel 2 is decelerated, the pushing device 33 is driven by hydraulic pressure, can rapidly push the compression roller assembly 31 when the flywheel 2 is decelerated, enables the compression roller 313 to decelerate the flywheel 2, can instantly relieve pressure when the deceleration is completed, timely cancels the limitation on the rotation of the flywheel 2, and avoids the situation that the deceleration excessively leads to the re-acceleration.
Because the compression roller 313 generates larger friction with the flywheel 2 when in use, the abrasion is larger, in order to facilitate the replacement of the compression roller 313, the telescopic shaft of the pushing device 33 is matched with the connecting hole 316 through threads, and when the compression roller 313 needs to be replaced, only the thread structure needs to be loosened, the compression roller assembly 31 is adjusted to be transverse, so that the compression roller 313 is completely exposed out of the flywheel 2; in order to prevent the screw thread from loosening in the using process, a round nut and a stop washer are further arranged on the telescopic shaft of the pushing device 33.
The rotating shaft of the compression roller 313 is provided with a rotating sensor which is electrically connected with the controller 7, so that the state of the compression roller 313 can be monitored in real time, and the compression roller is prevented from rubbing with the flywheel 2 when the speed is not reduced, and the straightening wheel 1 is prevented from running abnormally to influence production.
In order to improve the braking performance and the speed reduction speed of the flywheel 2, the number of the braking mechanisms 3 is three, and the braking mechanisms are uniformly distributed around the flywheel 2.
The principle of the invention is as follows: winding the copper material on the straightening wheel 1 and passing through related straightening equipment, and meanwhile, slowly increasing the rotating speed of the variable frequency motor 5 through the electric control cabinet 4 to assist the traction of the copper material; when the copper material reaches a rolling position, the variable frequency motor 5 is enabled to be at a rated working rotating speed through the electric control cabinet 4 for straightening; when the copper material slips due to over-high rotating speed or the tension of the copper material needs to be adjusted due to other reasons, the input frequency of the variable frequency motor 5 is reduced through a variable frequency knob in the electric control cabinet 4, the controller 7 obtains a set value of the electric control cabinet 4 at the moment, when the speed sensor 6 learns that the rotating speed of the flywheel 2 is greater than the set value, the controller 7 starts the pushing device 33 to push the compression roller assembly 31 to the flywheel 2, so that the compression roller 313 is in contact with the flywheel 2, and the compression roller 313 rotates in a compressed state to generate resistance, so that the flywheel 2 is decelerated; when the rotating speed of the flywheel 2 reaches a set value, the controller 7 controls the pushing device 33 to release pressure, the compression roller 313 is in a free rotating state at the moment, the rotation of the flywheel 2 cannot be hindered, excessive deceleration is avoided, then the controller 7 controls the pushing device 33 to enable the telescopic shaft of the compression roller 313 to contract, the compression roller 313 is separated from the flywheel 2, and the phenomenon that resistance is generated due to excessive abrasion or unsmooth rotation of the compression roller 313 to influence the rotation of the flywheel 2 is avoided.
The design key point of the invention is that the flywheel is coaxially arranged on the straightening wheel, so that the rotation inertia of the straightening wheel is increased, the rotation of the straightening wheel is more stable, and the straightening effect is favorably improved; the brake mechanisms are arranged around the flywheel and controlled by the controller, so that resistance can be applied to the flywheel during deceleration, the deceleration of the flywheel is accelerated, and the straightening effect is ensured.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
