Structure Flying Shear And Working Principle


With the rapid development of rolling mills, flying shear has become indispensable equipment in continuous rolling lines, mainly for hot-rolled and cold-rolled, cutting head, cutting tail, cutting the sample as well as incident handling, including cold-rolled strip steel drum flying shear.


A steel rolling mill operation frequently appeared on the shears that cannot cut the strip normally phenomenon, causing huge economic losses.

To make concerned people fully understand the roller structure and working principle, therefore, it is necessary that summed up its maintenance and repair experience to maintain the normal operation of the production and improve the economic efficiency of enterprises.


Structure Flying Shear and Working Principle  

Typical Structure

Generally, the drum-type mill bearing is composed of three parts flying shear body gear and equipment lubrication piping, which chassis and rotating hub into one. As whole equipment, it is not only set up to replace the pair but often transfer hub, simple structure rigidity, and high cutting precision. The body of the flying shear machine, including the transmission mechanism, and cutting mechanism. Flying shear drive mechanism, mainly by the electric motor, gearbox, and synchronous transmission gear mounted on the upper and lower rollers on the drive side of the composition.

When flying shear is worked by a 1 or 2-motor drive inverter that controls two rollers. Flying shear cutting mechanism by bladed upper and lower rollers composed by relative rotation, to achieve the upper and lower blade cutting edge dislocation on the strip shear. At the same time, in the terms of the same unit of production strip thickness and strength will change. In order to meet the production needs of the unit flying shear mechanism.

All in all, further comprising means for adjusting the gap side, we must improve the function of shear capacity to achieve changes in the blade gap.
