Abstract
The invention discloses a speed mechanical control structure which comprises a rack, position guiding rollers, a tensioning roller, a flywheel, a rack wheel, and pinions. At the front end of rolling mill equipment, the rack is arranged at an ultra-thin strip rolling inlet, and the two position guiding rollers and the tensioning roller are arranged in the rack. The two position guiding rollers are mounted at the upper part of the rack, and the tensioning roller is mounted at the lower part of the rack and between the two position guiding rollers. Each pinion is mounted at the roll neck at one end of each position guiding roller, the rack wheel is mounted on the shaft neck of the flywheel, and the pinions on the position guiding rollers and the rack wheel on the flywheel are meshed. The speed mechanical control structure is simple and easy to maintain, the effect of controlling the speed fluctuation of the ultra-thin strip rolling inlet is good, and the principle and method have feasibility.
Description
Technical field
The present invention relates to a kind of speed mechanical control structure, belong to rolling technical field.
Background technology
In high-speed rolling process, the fluctuation of fast mill rolling entrance velocity, causes the fluctuation of roll-force, causes the flutter of fast mill, has a strong impact on the quality of rolled steel product.Due to the defect of the rolling aluminium foil product surface quality that the flutter of milling train causes, as rolled products vibration line, being ubiquitous problem during rolling aluminium foil is produced, is also the technical barrier of puzzlement rolling industry in world wide.Vibration line refers to the light and dark striped that band milling material surface is formed, the quality of the generation not only influence of rolled product of vibration line, and the violent flutter of milling train also can cause broken belt or device damage accident, threatens production safety also to cause huge economic loss.
Therefore, improve the surface quality of rolled steel product, suppressing the open defects such as vibration line, fundamentally, is by various device controlled rolling entrance velocity.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of speed mechanical control structure.
The technical scheme that technical solution problem of the present invention is taked is:
A kind of speed mechanical control structure, comprises frame, leads a roller, idler roller, flywheel, gear wheel and pinion.
In milling equipment front end, the rolling porch of ultra-thin strip is provided with frame, is provided with two and leads a roller and an idler roller, wherein lead the top that a roller is arranged on frame for two in frame, idler roller is arranged on the bottom of frame, and idler roller is installed on two and leads in the middle of a roller.
Pinion is arranged on the roll neck place, one end leading a roller, and gear wheel is arranged on the axle journal of flywheel, leads the fit system that the pinion on a roller and the gear wheel on flywheel are gears meshing.
Beneficial effect of the present invention: a kind of speed mechanical control structure that the present invention proposes, the frame for movement of its device is simple, is easy to maintenance, and control the effective of ultra-thin strip rolling entrance velocity fluctuation, its Principle Method has feasibility.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of speed mechanical control structure, its structure comprises: frame 1, lead a roller 4, idler roller 5, flywheel 3, gear wheel 11, pinion 12 and milling equipment.
As shown in Figure 1, in milling equipment front end, the frame 1 of the rolling porch setting device of ultra-thin strip 2, its sprocket bit roller 4 is arranged on the upper part of frame 1, and idler roller 5 is arranged on the lower part of frame 1, and idler roller 5 is installed on two and leads in the middle of a roller 4;
As shown in Figure 2, pinion 12 is arranged on the left end roll neck place leading a roller 4, on the axle journal of gear wheel 11 Flywheel 3, leads the kind of drive that the pinion 12 on a roller 4 and the gear wheel 11 on flywheel 3 are gears meshing.
As depicted in figs. 1 and 2, lead a roller 4 one and have two, two structures leading a roller are identical, at the left end roll neck place leading a roller, install pinion 12; Described idler roller 5 pairs of rolling ultra-thin strips 2 have the effect supporting tensioning.
As shown in Figure 2, gear wheel 12 is installed at the axle journal place of flywheel 3, and flywheel 3 has a large the moment of inertia.
As shown in Figure 1, milling equipment comprises rolling-mill housing 6, upper backup roll 7, top working roll 8, bottom working roll 9 and lower backing roll 10.
As depicted in figs. 1 and 2, in the operation of rolling of ultra-thin strip 2, in the rolling porch of milling equipment rolling ultra-thin strip 2, the horizontal movement of ultra-thin strip 2 is through the support tensioning of idler roller, the rotation of a roller 4 is led in drive two, the pinion 12 of leading on a roller 4 drives the gear wheel 11 on flywheel 3 by meshed transmission gear mode, thus drive flywheel 3 to rotate, flywheel 3 has a larger the moment of inertia, therefore the present invention can make the rolling entrance velocity of ultra-thin strip more stable, serves the effect of the fluctuation of ultra-thin strip rolling entrance velocity in controlled rolling process.
