The disc shear is a process device of a continuous annealing unit, can shear the edge of the strip steel and ensures the width of the strip steel. The continuous annealing unit in certain factory 2150 is the widest domestic strip steel production line at present, see fig. 1, strip steel enters the edge cutting shears through the deviation correcting roller before the cutting of the disc shears, the edge of the strip steel weld joint is cut through the edge cutting shears, and then the edge is cut through the disc shears, so that the continuous production is ensured. 2150 continuously moves back the disc shear of production line and is disc double shear disc shear, its main advantage is steady operation, the clearance numerical control of cutting edge can carry out quick tool change. When thin strip steel with the width of more than 1800mm and the thickness of less than 0.6mm is produced from the production, after crescent bending shearing is carried out on the welding seam, the edge clamping occurs when the disc shear feeds for many times, the sagging of the strip steel edge causes poor shearing effect, the sheared edge material deforms, and the chute blocks the edge. The reason for this is that after the strip steel is cut, the strip steel cannot enter between the upper cutting edge and the lower cutting edge to cause edge clamping when the disc shear feeds due to the fact that the strip steel is small in tension and the sagging phenomenon occurs at the edge of the strip steel under the influence of gravity. After the accident occurs, the treatment time is long, and more degradation products are generated. Therefore, the cutting edge clamping of the circle shear is effectively avoided, and the method has positive significance for the stable operation of the unit.
In order to solve the problem of cutting edge clamping of the rotary shears, the cutting condition of the edge part of the strip steel is generally monitored on line by adopting manpower, and the edge part of the strip steel is required to be lifted manually for cutting when the sagging of the strip steel is found. But there is a risk of handling the edges of the strip on-line.
