Drying box of test grinding wheel

Abstract

The invention discloses a drying box of a test grinding wheel. The box comprises a box body, a control switch and a temperature button are arranged on the left side of the box body, a plurality of heating tubes are correspondingly hoisted on the side wall and the rear wall of the drying box, a rotating disc is arranged at the bottom of the box body, a driving mechanism is arranged on one side of the rotating disc, a drying rack with a plurality of layers of separating plates is installed on the rotating disc, and the included angle between each layer of the separating plate of the drying rackand the horizontal plane is 30-45 degrees; and a limiting hole is formed in the other side of the rotating disc, and a lifting mechanism is arranged at the position, corresponding to the limiting hole, of the bottom plate of the box body; and a spring is installed on the lifting mechanism, a positioning block is installed on the spring, and the outer diameter of the positioning block is smaller than the diameter of the limiting hole. According to the box, the structure is simple, the design is ingenious, through the arrangement of the rotating disc at the bottom of the drying box, the drying rack is arranged on the rotating disc, and then the test grinding wheel is arranged on the separating plate of the drying rack, the rotation of the rotating disc realizes omni-directional and uniform drying of the grinding wheel, so that cracks generated on the surface of the grinding wheel due to non-uniform drying are avoided, and the rejection rate is reduced.

Description

technical field [0001] The invention relates to the technical field of grinding wheel testing equipment, in particular to a drying box for testing grinding wheels. Background technique [0002] The grinding wheel is a circular bonded abrasive with a through hole in the center made of abrasives and bonds. Grinding wheel is the most widely used type of grinding tool. It rotates at high speed during use and is suitable for processing various metal and non-metal materials. The grinding wheel is a porous body made by adding a binder to the abrasive, compacting, drying and firing. [0003] The drying of the grinding wheel is a process of heat transfer and mass transfer. The hot air as the heat transfer medium transfers heat to the surface of the grinding wheel by convection heat transfer, and then the heat on the surface of the grinding wheel is transferred to the inside of the grinding wheel in the form of heat conduction. On the one hand, the heat is used to heat the grinding ...
