Description
Technical Field
The invention relates to the field of metallurgical machinery, in particular to a shear blade gap adjusting device.
Background
In a steel rolling production line, flying shears for shearing rolled pieces are one of key devices of the steel rolling production line, the flying shears are generally used for cutting heads, tails, double-length, segmentation and accident breaking of the rolled pieces, one of important indexes of finished rolled material quality is the size of burrs during shearing by the flying shears, and therefore the numerical value of the cutting edge gap of the flying shears is required to be accurate. At present, the adjustment of the blade clearance of the crank flying shear mostly adopts an adjustment method of adding or subtracting a gasket between the shear and a tool rest, and the adjustment of the blade clearance of the existing crank flying shear is as follows: and measuring the gap and the contact ratio between the upper and lower shear blades, calculating the thickness to be increased or decreased according to the process requirement, then unscrewing the screw for fixing the scissors, adding the vertical gasket and the horizontal gasket between the tool rest and the scissors, and screwing the screw. If it is not suitable to add the clearance between the measuring scissors sword behind the gasket, still need take off the scissors again, the operation of repetition first time, operating procedure is many, and dismouting bolt is in large quantity, wastes time and energy very much, influences output.
