Description

technical field [0001] The invention relates to the technical field of machine tool cooling, in particular to a machine tool temperature control system. Background technique [0002] A machine tool is a machine that processes metal blanks into mechanical parts. Due to frequent cutting, extrusion and friction between the workpiece and the processing tool, the temperature of the processing tool and the workpiece is very high. When the temperature at the processing place is too high, it will It will affect the processing tool and workpiece, resulting in the decrease of processing accuracy and damage of the tool. At this time, it is necessary to cool down the processing place; at present, the liquid spray pipe is usually used to spray the processing part to cool the processing tool and the workpiece. Some machine tools use coolant with lubricating effect, so that during the cooling process, the lubrication of the processing tool and the workpiece can be realized; but this coolin...

[0002] A machine tool is a machine that processes metal blanks into mechanical parts. Due to frequent cutting, extrusion and friction between the workpiece and the processing tool, the temperature of the processing tool and the workpiece is very high. When the temperature at the processing place is too high, it will It will affect the processing tool and workpiece, resulting in the decrease of processing accuracy and damage of the tool. At this time, it is necessary to cool down the processing place; at present, the liquid spray pipe is usually used to spray the processing part to cool the processing tool and the workpiece. Some machine tools use coolant with lubricating effect, so that during the cooling process, the lubrication of the processing tool and the workpiece can be realized; but this cooling method is to continuously cool the processing area, often to achieve better However, the temperature change is complex and the temperature change trend is changeable, resulting in a variety of temperature distributions in the process of cooling the processing place. At this time, it is difficult to manually The temperature distribution regulates the working status of each component in stages, and it is even more difficult to select a suitable cooling mode according to different temperature distributions, which affects the cooling effect of the processing area to a large extent, and also hinders the processing of the processing area to a certain extent.
