Dry-cold grinding device for grinding machine

Abstract

The invention relates to a cooling system for grinding process of a grinding machine, in particular to a dry-cold grinding device for the grinding machine. The dry-cold grinding device for the grinding machine comprises an infrared thermo detector, a controller, a nozzle and an air cooling mechanism. The infrared thermo detector and the nozzle are arranged over a grinding area where the grinding wheel and work piece are engaged with each other; the nozzle is connected with the air cooling mechanism; and the infrared thermo detector outputs signals and then connected with the controller after the signals are converted into voltage signals, and the controller controls the flow output to the nozzle by the air cooling mechanism. The air cooling mechanism comprises an air compressor, an air storage cylinder, an air drier, an air purifier, an air refrigerating unit and a flow adjusting valve, which are sequentially connected; and the output end of the flow adjusting valve is connected with the nozzle, and the controller outputs signals to be connected with the flow adjusting valve. The device takes hypothermal compressed air as a cooling medium to remove the heat produced in the grinding process, thereby overcoming the defects caused by a grinding fluid, improving the working environment and reducing the production cost.

Description

technical field [0001] The invention relates to a cooling system for grinding processing of a grinding machine, in particular to a dry cooling grinding device of the grinding machine. Background technique [0002] Due to the high cutting speed and fine chips and abrasive dust in grinding, it is easy to dust the surrounding air. To prevent dusting of the air, cutting fluid is required; at the same time, in order to prevent the workpiece from being burned and cracked, cooling is required, and cooling and cooling also require cutting fluid. liquid. However, during the use, treatment and discharge of cutting fluid, it not only causes serious pollution to the environment, but also causes harm to the health of operators, and the related costs are very high. Relevant studies have shown that: the active additives contained in the cutting fluid have a degreasing effect on human skin, and long-term contact with operators will make the skin rough and dry; the organic amines and inorga...

Problems solved by technology

[0004] With the development of manufacturing technology, the processing efficiency of metal cutting machine tools is getting higher and higher, and the amount of cutting fluid is increasing. Simply relying on increasing the amount of cutting fluid to reduce the cutting temperature can no longer meet the needs of production. Further aggravating the impact on the environment has attracted more and more attention from the society
