Double-sided rough and fine polishing device for steel strip

Abstract

The invention discloses a double-sided rough and fine polishing device for a steel strip. The double-sided rough and fine polishing device comprises a rack and a polishing assembly, wherein the polishing assembly comprises rough polishing wheels and fine polishing wheels. The polishing device further comprises two groups of dust cleaning devices, wherein the dust cleaning devices are arranged at steel strip outlet sides of the rough polishing wheels and the fine polishing wheels respectively; each dust cleaning device comprises a fixed rod, a connecting element and a cleaning brush, each fixed rod is fixedly connected to the rack, and each cleaning brush is connected with the corresponding fixed rod through the corresponding connecting element; each fixed rod is fixedly connected with the corresponding connecting element, and each cleaning brush is detachably connected with the corresponding connecting element; and the axis of each fixed rod is parallel to the axis of the corresponding rough polishing wheel / fine polishing wheel, and the cleaning brush on the corresponding connecting element is intersected with a tangent line between the corresponding rough polishing wheel and the corresponding fine polishing wheel at the same side as the steel strip. The polishing device is high in working efficiency, and capable of avoiding the phenomena of the burning of waste heat on the steel strip for the steel strip after polishing, and the damages of the subsequent procedures to the steel strip; and moreover, the polishing device disclosed by the invention is also capable of preventing the dust generated after polishing from floating everywhere and polluting environment.

Description

technical field [0001] The invention belongs to the technical field of polishing, in particular to a double-sided thickness polishing device for a steel strip. Background technique [0002] Steel strip is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Steel strips are generally supplied in rolls, and have the advantages of high dimensional accuracy, good surface quality, easy processing, and material saving. However, both the inner and outer surfaces of the newly produced steel strip usually need to be polished. Traditional polishing machines usually only polish one side of the steel strip, and after the polishing is completed, the reverse side needs to be polished again, which not only has low work efficiency, but also causes damage to the steel strip after repeated operations. In addition, there will be steel debris and dust lef...
