Method for improving grinding efficiency of shear blade

Abstract

The invention provides a technology for improving the grinding efficiency of a shear blade, which comprises the steps of carrying out group grinding on shear blade curved surfaces with similar curves; increasing the using space of a grinding wheel, increasing the thickness of a grinding wheel piece to enable the thickness to be in a range of 80-100mm; adjusting the height of a grinding wheel dresser for dressing other grinding curved surfaces when the second new grinding curved surface is formed on the same grinding wheel; when the grinding wheel piece has an inclination angle and is scrapped, forming the second new grinding curved surface on the same grinding wheel, and coping the grinding wheel again after uninstallation is carried out, wherein each grinding wheel can be used for carrying out correction grinding on four identical curved surfaces, the middle grinding thickness range of the grinding wheel piece is greater than or equal to 20mm, and the thickness of a ground curved surface is smaller than or equal to the distance from a flange of the grinding wheel piece to the excircle of the grinding wheel piece. Compared with the prior art, the technology has the beneficial effects that the labor intensity can be reduced, the depreciation speed of a machine tool is effectively reduced, the auxiliary installing time is greatly reduced, and the energy consumption, the electricity consumption, the water consumption and the cutting fluid consumption are greatly reduced.

Description

technical field [0001] The invention relates to the field of metallurgical processing, in particular to a method for improving the grinding efficiency of shear blades. Background technique [0002] In the hot strip steel production line, the cutting blades used on the flying shear equipment for cutting the head and tail before the finish rolling, each flying shear has 3 to 4 pairs of cutting blades that work alternately, and the rough rolling blanks are used in the finishing rolling Before cutting the irregular head and tail of the blank. The structure of the cutting edge is complex, each cutting edge is composed of 4 to 6 curved surfaces, and the grinding requires high processing precision. During the grinding process, each forming curved surface must be ground with a special curved surface grinding wheel, and the grinding process is complicated. , The dressing of the grinding wheel is difficult, the auxiliary process is too long, the processing efficiency is low, and the ...
