Instrument for metal piece surface low-temperature grinding derusting and polishing treatment

Abstract

The invention discloses an instrument for metal piece surface low-temperature grinding derusting and polishing treatment. The instrument comprises an upper control cabinet, a grinding device and a lower draining box; a sliding rod motor in the upper control cabinet drives an upper sliding rod and a lower sliding rod to rotate, a sliding groove is formed between the upper sliding rod and the lower sliding rod, the lower sliding rod is sleeved with a grinding groove, a pressing block in sliding connection with the grinding groove is sleeved with the grinding groove, a magnet in sliding connection with the pressing block is arranged in the pressing block, a grinding disc is arranged below the grinding groove, a material piece is arranged between the magnet and the grinding disc, and a water injection pipe is arranged on the draining box. The instrument has the beneficial effects that gravity is used for enabling the pressing block to be arranged in the grinding groove, the magnet is used for enabling the material piece to be attracted in a bottom face groove of the pressing block, the parallelism degree of the surface of the material piece is ensured, after upward moving and retracting of a lower sliding rod in the sliding groove, a rotating shaft is rotated to enable a grinding device to move, the grinding disc can be conveniently replaced, a wet grinding method is adopted in the instrument, in the grinding process, cooling is achieved through cooling liquid, and the lattice structure changing caused by too high temperature of the material piece in the grinding process can be effectively prevented.

Description

technical field [0001] The invention relates to a device for grinding and removing oxide film and derusting a material sheet, in particular to an instrument for grinding, derusting and polishing the surface of a metal sheet at low temperature. Background technique [0002] At present, most of the metal sheets used in chemical experiments need to be polished with sandpaper before the experiment. The surface of the artificially polished metal sheets is not smooth enough and cannot guarantee that the oxide film and rust on the surface will be completely removed, which will affect the accuracy of the experiment. Heat can cause changes in the shape of the metal lattice to affect the experiment, requiring a wet grinder that cools down through cooling fluid during the grinding process. Contents of the invention [0003] The object of the present invention is to provide an instrument for low-temperature grinding, derusting and polishing treatment of the surface of a metal sheet, s...
